Answer B is correct. She forgot to use a variable for 1.49. The correct equasion would be:
1.25x + 1.49y = 100

Answer:

B. Barbara’s equation did not consider the number of iced tea drinks.

Step-by-step explanation:

Barbara sells iced tea for a $1.49 per bottle and water for $1.25 per bottle.

She wrote a equation to find the number of drinks she needs to sell to earn $100.

1.25x+1.49=100 ; here x is the number of water bottles sold.

She forgot to write a variable with 1.49 like :

1.25x+1.49y=100

Therefore, the answer is : Barbara’s equation did not consider the number of iced tea drinks.

Suppose the true proportion of high school juniors who skateboard is 0.18. If many random samples of 250 high school juniors are
madreJ [45]

Answer:

0.024

Step-by-step explanation:

Central Limit Theorem

The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean \mu and standard deviation \sigma, the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean \mu and standard deviation s = \frac{\sigma}{\sqrt{n}}.

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean \mu = p and standard deviation s = \sqrt{\frac{p(1-p)}{n}}

Suppose the true proportion of high school juniors who skateboard is 0.18.

This means that p = 0.18

Samples of 250 high school juniors are taken

This means that n = 250

By how much would their sample proportions typically vary from the true proportion?

This is the standard error, so:

s = \sqrt{\frac{p(1-p)}{n}}

s = \sqrt{\frac{0.18*0.82}{250}}

s = 0.024

So 0.024 is the answer.

The area of a sector of a circle with a radius measuring 15 cm is 75(pi) cm2. What is the measure of the central angle that form
anyanavicka [17]

The sector of the circle is bounded by 2 radii, and the measure of the central angle that forms the sector is 120 degrees

<h3>How to determine the central angle?</h3>

The given parameters are:

  • Area = 75π cm^2
  • Radius, r = 15 cm

The area is calculated using

Area = α/360 * πr^2

So, we have:

α/360 * π * 15^2 = 75π

Evaluate the exponent

α/360 * π * 225 = 75π

Divide both sides by 75π

α/360 * 3 = 1

Multiply

α/120  = 1

Multiply both sides by 120

α = 120

Hence, the measure of the central angle that forms the sector is 120 degrees
