This graph has a positive correlation. This means that as the temperature increases along the bottom, the values on the vertical axis also increase.

This could be the number of ice cream cones sold at a shop. This makes sense, because as it gets warmer people are generally likely to buy more ice cream.

Answer d is 65 c is 63 b is 33 a is 31

frosja888 [35]

Answer:

c. 63 toothpicks

Step-by-step explanation:

ok so the base for 16 would be 16 toothpicks

when i first see it that no matter what we would be multiplying 16 by 3 for that triangle shape

16 x 3 = 48

then we would have 15 for the connection toothpicks

48 + 15 = 63

16 would have 63 toothpicks

Find the midpoint of the line segment with end coordinates of:<br> (-3,-1) and (-4,2)

fgiga [73]

Answer:

(- 3.5, 0.5 )

Step-by-step explanation:

Given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is

( $\frac{x_{1}+x_{2} }{2}$ , $\frac{y_{1}+y_{2} }{2}$ )

Here (x₁, y₁ ) = (- 3, - 1) and (x₂, y₂ ) = (- 4, 2) , then

midpoint = ( $\frac{-3-4}{2}$ , $\frac{-1+2}{2}$ ) = ( $\frac{-7}{2}$ , $\frac{1}{2}$ ) = (- 3.5, 0.5 )

The distribution of the number of siblings for students at a large high school is skewed to the right with mean 1.8 siblings and

morpeh [17]

Answer:

E. Approximately normal with standard deviation less than 0.7 sibling

Step-by-step explanation:

To solve this question, we use the Central Limit theorem.

Central Limit Theorem

The Central Limit Theorem estabilishes that, for a random variable X, with mean $\mu$ and standard deviation $\sigma$ , a large sample size can be approximated to a normal distribution with mean $\mu$ and standard deviation $s = \frac{\sigma}{\sqrt{n}}$

In this problem, we have that:

Skewed right distribution, with $\mu = 1.8, \sigma = 0.7$

Sampling distribution of the sample mean for samples of size 100

By the Central Limit Theorem, they will be approximately normal, with mean $\mu = 1.8$ , and standard deviation $s = \frac{0.7}{\sqrt{100}} = 0.07$

So the correct answer is:

E. Approximately normal with standard deviation less than 0.7 sibling
