Suppose the dosage for an adult is 150 mg.
(a) Find the slope of the graph of e. (Round your answer to two decimal places.)
P
What does it represent?
The slope represents the Select of the dosage for a child for each change of 1 year in age.
(b) What is the dosage for a newborn? (Round your answer to two decimal places.)
ma
a) The slope shows that the appropriate dose c for an older child increases by 6.225 mg if the child is one year older.
b) The dose for newborn baby is: 6.225 mg
How to interpret the slope?The equation of a line in slope intercept form is:
y = mx + c
where:
m is slope
c is y-intercept
(a) Let a be an age of an child in years. Then:
c = 0.0417Da + 0.0417D

The diamond suit from a standard deck of cards are taken out. You draw 2 cards from only the diamonds. What are the chances that you draw a king on your first draw and an ace on your second?
Answer:
There are 13 diamonds in a deck of cards, including one king and one ace.
The probability of drawing a king on the first draw is 1/13, since there is one king among 13 diamonds.
Assuming that the king is not replaced, there are now 12 diamonds left, including one ace. The probability of drawing an ace on the second draw is 1/12, since there is one ace among 12 diamonds.
The probability of drawing a king on the first draw and an ace on the second draw is the product of these probabilities:
P(king first, ace second) = P(king first) * P(ace second|king first not replaced)
P(king first, ace second) = (1/13) * (1/12)
P(king first, ace second) = 1/156
Therefore, the chances of drawing a king on your first draw and an ace on your second draw, when drawing 2 cards from only the diamonds, is 1/156.

Fwam and Eva are both driving along the same highway in two different cars to a stadium in a distant city. At noon, Fwam is gar miles away from the stadium and Eva is 396 miles away from the stadium. Fwam is driving along the highway at a speed of 42 miles per hour and Eva is driving at speed of 65 miles per hour. Let F represent Fwam's distance, in miles, away from the stadium t hours after noon. Let E represent Eva's distance, in miles, away from the stadium t hours after noon. Write an equation for each situation, in terms of t, and determine how far both Fwam and Eva are from the stadium at the moment they are an equal distance from the stadium.
Fwam and Eva are an equal distance of 69 miles away from the stadium when the time t = 3 hours
Given data ,
The formula for the distance (F) of Fwam from the stadium is:
F(t) = 327 - 42t
Since Fwam is travelling at a 42 mph pace, his distance from the stadium is reducing at a 42 mph rate.
The formula for Eva's separation from the stadium is:
E(t) = 396 - 65t
Eva's distance from the stadium also shrinks at a pace of 65 miles per hour as she drives at a speed of 65 mph.
Set F(t) = E(t) and solve for t to get the time at which Fwam and Eva are equally far from the stadium
On simplifying the equations , we get
327 - 42t = 396 - 65t
Adding 65t to both sides:
65t + 327 - 42t = 396
23t + 327 = 396
Subtracting 327 from both sides:
23t = 396 - 327
23t = 69
Dividing both sides by 23:
t = 69 / 23
t = 3 hours
Hence , at t = 3 hours after noon, both Fwam and Eva are an equal distance of 69 miles away from the stadium.

Construct a sinusoidal function that rises from a minimum point at (3,-2) to a maximum point at (7, 8)
The sinusoidal function that rises from a minimum point at (3,-2) to a maximum point at (7, 8) is y = 5 sin(π/2(x - 3)) + 3
We are given that;
Minimum point= (3,-2)
Maximum point= (7, 8)
Now,
To construct a sinusoidal function that rises from a minimum point at (3,-2) to a maximum point at (7, 8), we can use the following steps:
Find the amplitude A. The amplitude is the distance from the midline of the function to the maximum or minimum point. The midline is the average of the maximum and minimum values, which is (8 + (-2))/2 = 3. The distance from 3 to 8 or -2 is 5, so A = 5.
Find the period P. The period is the length of one cycle of the function, or the horizontal distance between two consecutive maximum or minimum points. In this case, the period is 7 - 3 = 4. The constant B is related to the period by the formula B = 2π/P, so B = 2π/4 = π/2.
Find the horizontal shift C. The horizontal shift is the amount that the function is shifted left or right from its standard position. In this case, we want the function to have a minimum point at x = 3, so we need to shift it right by 3 units. This means that C = 3.
Find the vertical shift D. The vertical shift is the amount that the function is shifted up or down from its standard position. In this case, we want the function to have a midline at y = 3, so we need to shift it up by 3 units. This means that D = 3.
Putting it all together, we get:
y = 5 sin(π/2(x - 3)) + 3
Therefore, by the function the answer will be y = 5 sin(π/2(x - 3)) + 3.

Kyla finds a pair of roller blades that she would like to purchase. They are originally priced at $110 but are marked 30% off. What is the final price Kyla will pay for the roller blades if the tax rate is 5%?
To find the final price Kyla will pay for the roller blades, we first need to calculate the amount of the discount.
Discount = 30% of $110Discount = 0.30 x $110Discount = $33So Kyla will get a discount of $33 off the original price of $110.
Next, we need to calculate the pre-tax price of the roller blades after the discount.
Pre-tax price = Original price - DiscountPre-tax price = $110 - $33Pre-tax price = $77So the pre-tax price of the roller blades after the discount is $77.
Finally, we need to calculate the final price Kyla will pay, including the 5% tax.
Tax amount = 5% of $77Tax amount = 0.05 x $77Tax amount = $3.85Final price = Pre-tax price + Tax amountFinal price = $77 + $3.85Final price = $80.85Therefore, the final price Kyla will pay for the roller blades, including tax, is $80.85.50 POINTS ANSWER FOR BRAINLIST SHOW YOUR WORK

a) Two real solutions.
b) Solutions: y = -6, y = 12
Step-by-step explanation:
The discriminant is defined as the expression b² - 4ac, which appears under the square root sign in the quadratic formula.
The value of the discriminant determines the nature of the solutions to the quadratic equation:
[tex]\boxed{\begin{minipage}{12 cm}\underline{Discriminant}\\\\$b^2-4ac$ \quad when $ax^2+bx+c=0$\\\\when $b^2-4ac > 0 \implies$ two real solutions.\\when $b^2-4ac=0 \implies$ one real solution.\\when $b^2-4ac < 0 \implies$ no real solutions (two complex conjugate solutions).\\\end{minipage}}[/tex]
To find the number and type of solutions of the given quadratic equation, first rewrite the equation in the form ax² + bx + c = 0.
[tex]\begin{aligned}(y-3)^2-10&=71\\y^2-6y+9-10&=71\\y^2-6y-1&=71\\y^2-6y-72&=0\end{aligned}[/tex]
Compare the coefficients:
a = 1b = -6c = -72Substitute the values of a, b and c into the discriminant formula:
[tex]\begin{aligned}b^2-4ac&=(-6)^2-4(1)(-72)\\&=36-4(-72)\\&=36+288\\&=324\end{aligned}[/tex]
As the discriminant of the given equation is greater than zero, there are 2 real solutions.
To solve the equation, we can use the quadratic formula:
[tex]x=\dfrac{-b \pm \sqrt{b^2-4ac}}{2a}\quad\textsf{when}\;\;ax^2+bx+c=0[/tex]
As we have already calculated that the discriminant is 324, we can substitute this, along with the values of a and b, into the formula:
[tex]\implies y=\dfrac{-(-6) \pm \sqrt{324}}{2(1)}[/tex]
[tex]\implies y=\dfrac{6 \pm \sqrt{324}}{2}[/tex]
Solve for y:

Solve m^2 − 6m = 3. Use the Quadratic Formula. Leave your answers as simplified radicals.
Show ALL your work.
Answer:
m = 3 + 2√3 or m = 3 - 2√3
Step-by-step explanation:
The given equation is:
m^2 - 6m = 3
We can rewrite the equation in standard quadratic form as:
m^2 - 6m - 3 = 0
We can use the quadratic formula to solve for m:
m = [-b ± √(b^2 - 4ac)] / 2a
where a = 1, b = -6, and c = -3.
Substituting these values, we get:
m = [-(-6) ± √((-6)^2 - 4(1)(-3))] / 2(1)
m = [6 ± √(36 + 12)] / 2
m = [6 ± √48] / 2
m = [6 ± 4√3] / 2
Simplifying the expression, we get:
m = 3 ± 2√3
Therefore, the solutions to the equation are:
m = 3 + 2√3 or m = 3 - 2√3

According to a National Center for Health Statistics, the lifetime odds in favor of dying from heart disease are 1 to 5, so the probability of dying from heart disease is
Answer:
The probability of dying from heart disease based on the given information is 1/6 or approximately 0.1667. This is because the odds in favor of dying from heart disease are 1 to 5, which means there is 1 chance of dying from heart disease for every 5 chances of not dying from heart disease.

it is biased because not everyone has accessible to modern technology, or that particular social media app. Not all park users use social media. It is biased because it is targeting a younger demographic, but excludes the youngest demographic as well, that are not allowed ot have social media.

Step-by-step explanation:
4 identical glasses and 4 identical jugs hold a total of 11.12 ℓ of water.
Each glass holds 0.33 ℓ of water.
How much water does each jug hold ?
Answer:
2.45ℓ
Step-by-step explanation:
0.33ℓ x 4 = 1.32ℓ (1ℓ 320 ml)
11.12ℓ - 1.32ℓ = 9.8ℓ (total in 4 jugs)
9.8ℓ ÷ 4 = 2.45ℓ (each jug)
hope this helped :)
