Step-by-step explanation:
is one prime or composite?
It's neither prime or composite.
1 only has a single factor which is 1, so you can't really say.
One is a prime number because it can only be gotten in multiplication equation by using 1x1 to get 1! If it was 12 where multiple equations could get it like 3x4 then it would be composite!

Multiplying a number by 2 two and then dividing by 3 is the same as multiplying by what number?
Answer:
2/3
Step-by-step explanation:
Let x be number
Multiply by 2 = x * 2
Now, divide by 3 = 2x ÷ 3 = [tex]\frac{2x}{3}[/tex]
So, this is same as multiplying 'x' by [tex]\frac{2}{3}[/tex]
What is meant by the term observed frequencies (O)?
a. The frequencies found in the population
b. The frequencies that are hypothesized for the population being examined
c. The frequencies calculated from the null hypothesis
d. The frequencies found in the sample
Answer:
The term observed frequencies are found in the sample.Hence, option 'd' is correct.
Step-by-step explanation:
Unlike the expected frequency which is obtained based on prediction, the observed frequency is the actual frequency that is determined from the experiment.
Therefore, we conclude that
The term observed frequencies are found in the sample.Hence, option 'd' is correct.

Step-by-step explanation:
A recipe uses 4 cups of milk to make 12 servings. If the same amount of milk is used for each serving, how many servings can be made from three gallons? Before you try that problem, answer the question below. How many cups will you need to find the number of servings for?
Answer:
144 servings
Step-by-step explanation:
Step 1
We convert 3 gallons to cups
1 gallon = 16 cups
3 gallons = x cups
x = 3 × 16 cups
x = 48 cups
Step 2
If
4 cups of milk = 12 servings.
48 cups of milk = x servings
Cross Multiply
4 × x = 48 × 12
x = 48 × 12/4
x = 144 servings
Therefore, 3 gallons of milk(48 cups) = 144 servings

Solve the equation. 2 + |t+ 6| = 12
Answer:
t = 4 or t = -16
Step-by-step explanation:
Let's solve your equation step-by-step.
2+|t+6|=12
|t+6|+2=12
Step 1: Add -2 to both sides.
|t+6|+2+−2=12+−2
|t+6|=10
Step 2: Solve Absolute Value.
|t+6|=10
We know eithert+6=10 or t+6=−10
t+6=10(Possibility 1)
t+6−6=10−6(Subtract 6 from both sides)
t=4
t+6=−10(Possibility 2)
t+6−6=−10−6(Subtract 6 from both sides)
t=−16

Suppose commute times in a large city are normally distributed and that 63.70% of commuters in this city take more than 22 minutes to commute one-way. If the standard deviation of such commutes is 6.3 minutes, what is the mean commute?
Answer:
The mean is 24.205
Step-by-step explanation:
Firstly, we need to get the z-score
From the question, the probability we have is the probability that commuters take more than 22 minutes to commute one-way
So the probability we had was;
P( x > 22)
So we need the z-score corresponding to 63.70% or simply 0.637
We can use the standard normal distribution table to get this
Mathematically, from the standard normal distribution table this is -0.35
z-score = (x- mean)/SD
-0.35 = (22-mean)/6.3
22-mean = -2.205
mean = 22 + 2.205 = 24.205

What is complex number?"The number of the form a + ib, where a, b are real numbers and [tex]i=\sqrt{-1}[/tex]"
What is De Moivre's theorem?"This theorem gives a formula for computing powers of complex numbers.
[tex](r(cos\theta+i~sin\theta))^n=r^n~(cos(n\theta)+i~sin(n\theta))[/tex] "
For given question,
We need to divide two complex numbers.
[tex]56(cos(33^{\circ}) + i sin(33^{\circ})) \div 7(cos(11^{\circ}) + i sin(11^{\circ}))[/tex]
Consider,
[tex]56(cos(33^{\circ}) + i~ sin(33^{\circ})) \div 7(cos(11^{\circ}) + i ~sin(11^{\circ}))\\\\=8[(cos(33^{\circ}) + i~ sin(33^{\circ})) \div (cos(11^{\circ}) + i ~sin(11^{\circ}))][/tex] ...........(i)
Consider the first complex number.
[tex](cos(33^{\circ}) + i sin(33^{\circ}))[/tex]
We can write this complex number as,
[tex]cos(3(11^{\circ}) )+ i sin(3(11^{\circ}))[/tex]
By De Moivre's theorem,
[tex]cos(3(11^{\circ}) )+ i~ sin(3(11^{\circ}))\\\\=(cos(11^{\circ})+ i~ sin(11^{\circ}))^3[/tex]
Substitute this value in (i),
[tex]56(cos(33^{\circ}) + i~ sin(33^{\circ})) \div 7(cos(11^{\circ}) + i ~sin(11^{\circ}))\\\\=8[(cos(33^{\circ}) + i~ sin(33^{\circ})) \div (cos(11^{\circ}) + i ~sin(11^{\circ}))]\\\\=8[(cos(11^{\circ}) + i~ sin(11^{\circ}))^3 \div 7(cos(11^{\circ}) + i~ sin(11^{\circ}))]\\\\=8[(cos(11^{\circ}) + i~ sin(11^{\circ}))^2]\\\\=8[(cos(2\times 11^{\circ}) + i~ sin(2\times 11^{\circ}))]~~~~~~~~~.............(De~Moivre's~theorem )\\\\=8(cos(22^{\circ}) + i~ sin(22^{\circ}))[/tex]
Therefore, [tex]56(cos(33^{\circ}) + i sin(33^{\circ})) \div 7(cos(11^{\circ}) + i sin(11^{\circ}))[/tex] is [tex]8(cos(22^{\circ}) + i~ sin(22^{\circ}))[/tex]

Which statement BEST describes how muscles respond to weight training? A. Weight training stretches the muscles' limits and makes the muscles longer. B. Weight training pushes the muscles' abilities, making the muscles gain endurance. C. Weight training stimulates the muscles and causes the muscle fibers to sit closer together. D. Weight training overloads muscles, which causes the body to respond by making muscle fibers larger. Please select the best answer from the choices provided. A B C D
Answer:B
Step-by-step explanation:
The statement that best describes how muscles respond to weight training is:
Weight training overloads muscles, which causes the body to respond by making muscle fibers larger.
Option D is the correct answer.
What is weight training?Weight training, also known as resistance training, involves performing exercises that place a load or resistance on the muscles.
This load creates small tears or damage to the muscle fibers, which the body then repairs and adapts to by making the muscle fibers larger and stronger.
We have,
Option A:
Weight training stretches the muscles' limits and makes the muscles longer, which is not an accurate description of how muscles respond to weight training.
While stretching exercises can increase muscle flexibility, weight training typically does not cause the muscles to become longer.
Option B
Weight training pushes the muscles' abilities, making the muscles gain endurance, which is partially true.
Weight training can increase muscle endurance by strengthening the muscles, but the primary response of the muscles to weight training is hypertrophy, not increased endurance.
Option C:
Weight training stimulates the muscles and causes the muscle fibers to sit closer together, which is not an accurate description of how muscles respond to weight training.
While weight training does stimulate the muscles, it does not cause the muscle fibers to sit closer together.
Thus,
Weight training overloads muscles, which causes the body to respond by making muscle fibers larger.

What is an equation of the line that passes through the points (6, -7)(6,−7) and (-6, 3)(−6,3)? Put your answer in fully reduced form.
Given:
A line passes through the points (6,-7) and (-6,3).
To find:
The equation of line.
Solution:
If a line passes through two points [tex](x_1,y_1)\text{ and }(x_2,y_2)[/tex], then the equation of line is
[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]
The line passes through the points (6,-7) and (-6,3). So, the equation of line is
[tex]y-(-7)=\dfrac{3-(-7)}{-6-6}(x-6)[/tex]
[tex]y+7=\dfrac{3+7}{-12}(x-6)[/tex]
[tex]y+7=\dfrac{10}{-12}(x-6)[/tex]
[tex]y+7=-\dfrac{5}{6}(x-6)[/tex]
Using distributive property, we get
[tex]y+7=-\dfrac{5}{6}(x)-\dfrac{5}{6}(-6)[/tex]
[tex]y+7=-\dfrac{5}{6}x+5[/tex]
Subtract 7 from both sides.
[tex]y=-\dfrac{5}{6}x+5-7[/tex]
[tex]y=-\dfrac{5}{6}x-2[/tex]
Therefore, the equation of line is [tex]y=-\dfrac{5}{6}x-2[/tex].
