a.) Approximately 80.67% of the shoppers have an e-mail account.
b.) Approximately 19.33% of the shoppers do not have computer access at home.
How are percentages calculated?(a) To find the percentage of shoppers who have an e-mail account, we need to add the number of people who have an e-mail account (44) to the number of people who do not have a computer at home but may still have an e-mail account (77).
44 + 77 = 121
So, 121 out of 150 shoppers have an e-mail account. To find the percentage, we can divide 121 by 150 and multiply by 100:
121/150 * 100 = 80.67%
Therefore, approximately 80.67% of the shoppers have an e-mail account.
(b) To find the percentage of shoppers who do not have computer access at home, we need to add the number of people who do not have a computer at home (7) to the number of people who have an e-mail account but may or may not have computer access at home (22).
7 + 22 = 29
So, 29 out of 150 shoppers do not have computer access at home. To find the percentage, we can divide 29 by 150 and multiply by 100:
29/150 * 100 = 19.33%
Therefore, approximately 19.33% of the shoppers do not have computer access at home.

The half-life of Palladium-100 is 4 days. After 16 days a sample of Palladium-100 has been reduced to a mass of 2 mg.
What was the initial mass (in mg) of the sample? --------------
What is the mass 7 weeks after the start?-------------
Answer:
32 mg6.57 µg or 0.00657 mgStep-by-step explanation:
You want the initial mass, and the mass after 7 weeks, of a sample of Palladium-100 with a half-life of 4 days and a mass of 2 mg after 16 days.
ModelThe amount of Palladium-100 remaining after t days can be modeled by ...
a(t) = (initial amount)·(1/2)^(t/(half-life period))
a(t) = a0·(1/2)^(t/4) . . . . . . where t is in days, and a0 is the initial amount
ApplicationUsing this model to find a0, we have ...
a(16) = 2 mg = a0·(1/2)^(16/4) = a0/16
a0 = 32 mg . . . . . . multiply by 16
The initial mass of the sample is 32 mg.
7 weeksThe mass after 7 weeks (49 days) will be ...
a(49) = (32 mg)·(1/2)^(49/4) ≈ 0.0065698 mg
The mass after 7 weeks is about 6.57 µg or 0.00657 mg.

in a kite, the measurements of the angles are 3x, 75, 90, and 120. Find the value of x. What are the measures of the angles that are congruent
x is 25 and the congruent angles in the kite are 25 and 155 degrees.
What is quadratic equation?
it's a second-degree quadratic equation which is an algebraic equation in x.
In a kite, the two pairs of adjacent angles are congruent. Let's call the congruent angles x and y:
x y
+---+ +---+
/ \ / \
+-------+-------+
\ / \ /
+---+ +---+
y x
We know that the measurements of the angles in the kite are 3x, 75, 90, and 120, so we can set up an equation based on the sum of the angles in a quadrilateral:
3x + 75 + 90 + 120 = 360
Simplifying this equation, we get:
3x + 285 = 360
Subtracting 285 from both sides, we get:
3x = 75
Dividing both sides by 3, we get:
x = 25
So x is 25. To find y, we know that the sum of x and y must be 180 (because they are congruent angles that add up to a straight line). So we can set up another equation:
x + y = 180
Substituting x = 25, we get:
25 + y = 180
Subtracting 25 from both sides, we get:
y = 155
Therefore, x is 25 and the congruent angles in the kite are 25 and 155 degrees.

Samuel went to the grocery store and purchased cans of soup and frozen dinners. Each can of soup has 300 mg of sodium and each frozen dinner has 450 mg of sodium. Samuel purchased 5 more frozen dinners than cans of soup and they all collectively contain 6000 mg of sodium. Write a system of equations that could be used to determine the number of cans of soup purchased and the number of frozen dinners purchased. Define the variables that you use to write the system.
the system of equations is: [tex]300x + 450y = 6000[/tex]
[tex]y = x + 5[/tex]
What best define about variables?Let's define the variables:
Let "x" be the number of cans of soup purchased by Samuel.
Let "y" be the number of frozen dinners purchased by Samuel.
According to the given information, each can of soup has 300 mg of sodium and each frozen dinner has 450 mg of sodium. Samuel purchased 5 more frozen dinners than cans of soup, so we can write the following equations:
The total sodium from cans of soup: 300x mg
The total sodium from frozen dinners: 450y mg
The total sodium from both cans of soup and frozen dinners: [tex]6000 mg[/tex]
So the first equation is:
[tex]300x + 450y = 6000[/tex] (since the total sodium from cans of soup and frozen dinners is 6000 mg)
Since Samuel purchased 5 more frozen dinners than cans of soup, we can write the second equation:
[tex]y = x + 5[/tex] (since y is 5 more than x)
Therefore, the system of equations is:
[tex]300x + 450y = 6000[/tex]

The states C and D spend a total of $56.8 million for tourism. The state C spends $1.8 million more than the state D. Find the amount that each state spends on tourism.
D spends $___ million on tourism , and state C spends $___million on tourism.
Let's denote the amount that state D spends on tourism as "x" million dollars. According to the given information, state C spends $1.8 million more than state D, so state C would spend "x + 1.8" million dollars on tourism.
The total amount spent by state C and state D combined is $56.8 million. So we can write the equation:
x + (x + 1.8) = 56.8
Now, we can solve this equation to find the values of x and x + 1.8, which represent the amount spent by state D and state C, respectively.
x + x + 1.8 = 56.8
2x + 1.8 = 56.8
2x = 56.8 - 1.8
2x = 55
x = 55 / 2
x = 27.5
So, state D spends $27.5 million on tourism, and state C spends $27.5 + $1.8 = $29.3 million on tourism.

The equation a² + b² = c² represents the Pythagorean theorem.
What is the Pythagorean theorem?This is a theorem that states that in a right-angled triangle, the square of the length of the hypotenuse (c) is equal to the sum of the squares of the lengths of the other two sides (a and b).
The Pythagorean theorem is used to find the length of one of the sides of a right-angled triangle when the lengths of the other two sides are known.
To solve the problem, you need to have at least two side lengths given. Then, you can use the equation to find the length of the third side. For example:
If you know the lengths of sides a and b and need to find the length of the hypotenuse (c):
Plug in the known values for a and b into the equation and solve for c.
Example: If a = 3 and b = 4, then 3² + 4² = c², which gives 9 + 16 = c², so c² = 25, and c = sqrt(25) = 5.

A certain coin is a circle with diameter 18 mm. What is the exact area of either face of the coin in terms of pie?
Answer:
[tex]81\pi[/tex] [tex]mm^2[/tex]
Step-by-step explanation:
Let's recall the formula for the area of a circle:
[tex]A = \pi r^2[/tex]
We are given the diameter, but the formula uses the radius. Since the radius is equal to one-half of the diameter, we can find the radius by doing this:
[tex]r = \frac{1}{2}d=\\\\r=\frac{1}{2}(18)= \\\\r=9[/tex]
Now that we've found the radius is 9 mm, let's substitute the values into the formula for the area of a circle. We have:
[tex]A = \pi r^2=\\A=\pi (9^2)=\\A=\pi (81)=\\A=81\pi[/tex]
So, we've found that the exact area, in terms of pi, of either face of the coin is [tex]81\pi[/tex] [tex]mm^2[/tex].
To find the area of the coin/a circle use this equation:
(a = area, r = radius, d = diameter)
[tex]\text{a = r}^2[/tex]
So we need to do for the radius.
[tex]\text{r} = \dfrac{\text{d}}{2}[/tex]
[tex]\text{r} = \dfrac{18}{2}[/tex]
[tex]\text{r} = 9[/tex]
Then solve
[tex]\text{a = 9}^2[/tex]

What is the value of x in this equation?
2x + 6
5
= −1(x - 11)
Answer:
To solve the equation 2x + 6/5 = -1(x - 11), we can use the distributive property of multiplication over addition/subtraction to simplify the right-hand side of the equation:
2x + 6/5 = -x + 11
Next, we can rearrange the terms so that all the x terms are on one side of he equation and all the constant terms are on the other side:
2x + x = 11 - 6/5
Combining like terms and simplifying the right-hand side, we get:
3x = 49/5
Dividing both sides by 3, we get:
x = 49/15
Therefore, the value of x in the equation 2x + 6/5 = -1(x - 11) is 49/15.

f(x) = 7
Answer: An even function is a function that satisfies the condition:
f(-x) = f(x)
Let's check which of the given functions satisfies this condition:
f(x) = (x - 1)^2
f(-x) = (-x - 1)^2 = x^2 + 2x + 1
f(x) = (x - 1)^2
The two expressions are not equal, so f(x) is not an even function.
f(x) = 8x
f(-x) = -8x = -f(x)
f(x) = 8x
The two expressions are equal with opposite signs, so f(x) is an odd function.
f(x) = x^2 - x
f(-x) = (-x)^2 - (-x) = x^2 + x
f(x) = x^2 - x
The two expressions are not equal, so f(x) is not an even function.
f(x) = 7
f(-x) = 7 = f(x)
f(x) = 7
The two expressions are equal, so f(x) is an even function.
Therefore, the only even function among the given functions is:

nterpretation of the number -24.
A. How many cupcakes she sold.
B. How much it cost to buy the ingredients for the cupcakes.
C. How much each cupcake cost.
D. What her profit is.
Answer: The best interpretation of the number -24 in the equation p = 2.75c-24 is option D: What her profit is.
The equation is in slope-intercept form, where the coefficient of c (2.75) represents the profit per cupcake and the constant term (-24) represents the fixed costs or expenses that Violet incurs regardless of how many cupcakes she sells.
In this case, the constant term of -24 represents the fixed costs such as the cost of ingredients, supplies, and other expenses that Violet incurs to make the cupcakes. This cost is subtracted from the total revenue generated by selling cupcakes to determine the profit. Therefore, the number -24 represents the fixed costs or expenses and its inclusion in the equation allows us to determine Violet's profit as a function of the number of cupcakes sold.

A set of exam scores is normally distributed and has a mean of 74.4 and a standard deviation of 8.3. What is the probability that a randomly selected score will be between 63 and 66?
The probability that a randomly selected score will be between 63 and 66 is approximately 0.0718, or 7.18%.
What is mean?
In statistics, the mean is a measure of central tendency, which is a way of describing the typical or central value of a set of data. The mean is also known as the average, and it is calculated by adding up all the values in a set of data and then dividing by the number of values in the set.
To find the probability that a randomly selected score will be between 63 and 66, we need to calculate the z-scores for these values and then find the area under the normal curve between these z-scores.
The z-score for a score of 63 is:
z = (63 - 74.4) / 8.3
z = -1.37
The z-score for a score of 66 is:
z = (66 - 74.4) / 8.3
z = -1.01
We can use a standard normal distribution table or calculator to find the area under the normal curve between these z-scores.
Using a standard normal distribution table, we find that the area to the left of a z-score of -1.01 is 0.1562, and the area to the left of a z-score of -1.37 is 0.0844. To find the area between these z-scores, we subtract the area to the left of -1.37 from the area to the left of -1.01:
P(-1.37 < z < -1.01) = 0.1562 - 0.0844 = 0.0718
So the probability that a randomly selected score will be between 63 and 66 is approximately 0.0718, or 7.18%.

Answer:
A. h'(2) = 5
B. m'(2) = -24
C. y = 8x - 31
D. j'(2) = 3/25 = 0.12
Step-by-step explanation:
When differentiating composite functions, use the chain rule.
[tex]\boxed{\begin{minipage}{5.4 cm}\underline{Chain Rule for Differentiation}\\\\$\left[f\left(g(x)\right)\right]'=f'\left(g(x)\right) \cdot g'(x)$\\\end{minipage}}[/tex]
Chain Rule: The derivative of a composite function is the product of the derivative of the outer function evaluated at the inner function and the derivative of the inner function.
Part AUsing the chain rule, if h(x) = g(f(x)) then h'(x) = g'(f(x)) ⋅ f'(x).
To find h'(2), substitute x = 2 into the differentiated equation:
[tex]\begin{aligned}h'(x)& = g'(f(x)) \cdot f'(x)\\\\\implies h'(2)& = g'(f(2)) \cdot f'(2)\\& = g'(5) \cdot 1\\& = 5 \cdot 1\\&=5\end{aligned}[/tex]
Therefore, h'(2) = 5.
Part BUsing the chain rule, if m(x) = f(x²) then m'(x) = f'(x²) ⋅ 2x.
To find m'(2), substitute x = 2 into the differentiated equation:
[tex]\begin{aligned}m'(x) &= f'(x^2) \cdot 2x\\\\\implies m'(2) &= f'(2^2) \cdot 2(2)\\&=f'(4) \cdot 4\\&=-6 \cdot 4\\&=-24\end{aligned}[/tex]
Therefore, m'(2) = -24.
Part CTo find the slope of the tangent line to the graph of k at x = 4, substitute x = 4 into the derivative of k(x).
If k(x) = f(g(x)) then k'(x) = f'(g(x)) ⋅ g'(x).
Therefore, the slope of the tangent line is:
[tex]\begin{aligned}k'(x) &= f'(g(x)) \cdot g'(x)\\\\\implies k'(4) &= f'(g(4)) \cdot g'(4)\\&= f'(5) \cdot 4\\&= 2 \cdot 4\\&= 8\end{aligned}[/tex]
Now calculate k(x) when x = 4:
[tex]\begin{aligned}k(x)&=f(g(x))\\\\\implies k(4) &= f(g(4))\\&=f(5)\\&=1\end{aligned}[/tex]
To write the equation of the tangent line, substitute the found slope m = 8 and point (4, 1) into the point-slope equation:
[tex]\begin{aligned}y-y_1&=m(x-x_1)\\y-1&=8(x-4)\\y-1&=8x-32\\y&=8x-31\end{aligned}[/tex]
Therefore, an equation for the line tangent to the graph of k at x = 4 is:
y = 8x - 31Part DTo find the derivative of j(x) use the quotient rule.
[tex]\textsf{If\;\;$j(x)=\dfrac{g(x)}{f(x)}$\;\;then:}\\\\\\j'(x)=\dfrac{f(x)g'(x)-g(x)f'(x)}{(f(x))^2}[/tex]
To calculate j'(2), substitute x = 2 into the equation:
[tex]\begin{aligned} \implies j'(2)&=\dfrac{f(2)g'(2)-g(2)f'(2)}{(f(2))^2}\\\\&=\dfrac{5 \cdot 1-2 \cdot 1}{(5)^2}\\\\&=\dfrac{5-2}{25}\\\\&=\dfrac{3}{25}\\\\&=0.12\end{aligned}[/tex]
Therefore, j'(2) = 3/25 = 0.12.
2À candy company claims that its jelly bean mix contains 15% blue jelly beans. Suppose that the candies are packaged at random in small bags containing about 200 jelly beans. What is the probability that a bag will contain more than 20% blue jelly beans?
We find that P(Z > 2.46) is roughly 0.007 using a calculator or a basic normal distribution table. The probability that a bag will contain more than 20% blue jellybeans is therefore approximately 0.007 or 0.7%.
Define probability?The probability of an event is the ratio of good outcomes to all other potential outcomes. The number of successful outcomes for an experiment with 'n' outcomes can be expressed using the symbol x.
Here in the question,
We can utilise the binomial distribution formula to resolve this issue. In a bag of 200 jelly beans, let X represent the proportion of blue jelly beans. Following that, X exhibits a binomial distribution with parameters of n = 200 and p = 0.15, where p is the likelihood of drawing a blue jellybean.
The formula for determining the likelihood of finding more than 20% blue jellybeans in a bag is:
P (X > 0.2 × 200) = P (X > 40)
Since n is large (200) and p is not too near to 0 or 1, we can utilise the usual approximation to the binomial distribution. We may determine the equivalent mean and standard deviation of the normal distribution by using the mean and variance of the binomial distribution:
μ = np = 200 × 0.15 = 30
σ = √ (np(1-p)) = √ (200 × 0.15 × (1-0.15)) = 4.07
Then, we can standardize the random variable X as:
Z = (X - μ) / σ
So, we have:
P(X > 40) = P((X - μ) / σ > (40 - μ) / σ)
= P(Z > (40 - 30) / 4.07)
= P(Z > 2.46)
We find that P(Z > 2.46) is roughly 0.007 using a calculator or a basic normal distribution table. The likelihood that a bag will contain more than 20% blue jellybeans is therefore approximately 0.007 or 0.7%.
