Step-by-step explanation:

By Question :-

Sum of numbers = 90 .
Difference of numbers = 18 .

Let :-

First Number be x .
Second number be y .

According to 1st condition :-

$: \implies$ x + y = 90

According to 2nd condition :-

$: \implies$ x - y = 18

Adding the equations :-

$: \implies$ 2x = 18 + 90

$: \implies$ 2x = 108

$: \implies$ x = 54

In a sample of 1000 randomly, selected consumers who had opportunities to send in a rebate claim form after purchasing a product

Alexxx [7]

Answer: $=(0.2232,0.2768)$

Step-by-step explanation:

The confidence interval for population proportion is given by :-

$p\ \pm z_{\alpha/2}\sqrt{\dfrac{p(1-p)}{n}}$

Given : Sample size : $n=1000$

The proportion of people selected consumers who had opportunities to send in a rebate claim form after purchasing a product said they never did so = $\dfrac{250}{1000}=0.25$

Significance level : $1-0.95=0.05$

Critical value : $z_{\alpha/2}=1.96$

Now, the 95% confidence Interval for the true proportion of such consumers who never apply for a rebate will be :-

$0.25\ \pm (1.96)\sqrt{\dfrac{0.25(1-0.25)}{1000}}\\\\\approx0.25\pm0.0268\\\\=(0.2232,\ 0.2768)$

Hence, a confidence Interval for the true proportion of such consumers who never apply for a rebate .

It is 17 miles to the mall how many inches is that on a map

Alona [7]

In order to answer that question, we need to know the scale of the map.
Without that information, no answer is possible.

I think you have it in the first part of the question ... the part you decided
not to post.
_________________________

OK. Now that you've provided the scale of the map,
answering the question is a piece-o-cake.
Use a proportion:

(1 inch on the map) / (4 miles on the ground) = ('x' on the map) / (17 miles on the ground)

Hailey is making 36 mini- pumpkin pies. Each pie takes 6 ounces of pumpkin. The cans of pumpkin are 2 pounds each. How many can

serious [3.7K]

1 pound = 16 ounces

6 ounces each pie

36 mini pies to make

36 × 6 = 216 ounces needed to make 36 mini pies

216 ÷ 16 = 13.5 pounds
if each can of pumpkin is 2 pounds,
13.5 ÷ 2 = 6.75 so that would be 7 cans of pumpkin
