Answer:

A

Step-by-step explanation:

f = 1/2s

Let s = 2  that means f = 1  That means for 2 cups of sugar there is 1 cup of flour.

This point must be on the graph

It is on A,  not on B, not on C

Which symbol can be used to correctly compare the two fractions?
tatyana61 [14]
<span> The real question you need to solve is "Is 1/4 greater than, equal, or less than 15/100?" At first glance it's hard to determine how they relate to each other. So first make both fractions use the same denominator. The easiest way to do this is multiply both the numerator and denominator of each fraction by the denominator of the other fraction. So 1/4 * 100/100 = 100/400 and 15/100 * 4/4 = 60/400 Now ask yourself "Is 100/400 greater than, equal, or less than 60/400?" and the answer is pretty obvious. 100/400 > 60/400. So the answer is ">".</span>

Licemer1 [7]

Answer:

Each person would get 29.25 pounds of chicken

Step-by-step explanation:

John is cooking 234 pounds of chicken.

He is making a dinner for 8 people, including himself.

This means that he wants to make dinner for just 8 people.

Hence, he would need to divide the 234 pounds of chicken into 8 places.

234 / 8 = 29.25 pounds

Each person would get 29.25 pounds of chicken.

A city planner wants to estimate the average monthly residential water usage in the city. He selected a random sample of 100 hou
hodyreva [135]

Answer:

The 90% confidence interval for the average monthly residential water usage for all households in this city is between 4401.3 gallons and 4598.7 gallons.

Step-by-step explanation:

We have that to find our \alpha level, that is the subtraction of 1 by the confidence interval divided by 2. So:

\alpha = \frac{1-0.9}{2} = 0.05

Now, we have to find z in the Ztable as such z has a pvalue of 1-\alpha.

So it is z with a pvalue of 1-0.05 = 0.95, so z = 1.645

Now, find the margin of error M as such

M = z*\frac{\sigma}{\sqrt{n}}

In which \sigma is the standard deviation of the population and n is the size of the sample.

M = 1.645*\frac{600}{\sqrt{100}} = 98.7

The lower end of the interval is the sample mean subtracted by M. So it is 4500 - 98.7 = 4401.3 gallons

The upper end of the interval is the sample mean added to M. So it is 4500 + 98.7 = 4598.7 gallons

The 90% confidence interval for the average monthly residential water usage for all households in this city is between 4401.3 gallons and 4598.7 gallons.
