Answer:

8 ounces of canned tomatoes and 1 cup of cooked macaroni.

Step-by-step explanation:

Since the recipe makes 8 servings and you only want to make 2 servings, all you have to do is divide the amount of ingredients by 4.

If 8 servings call for 32 ounces of canned tomatoes, we only need 8 ounces of canned tomatoes to make 2 servings.

If 8 servings call for 4 cups of cooked macaroni, we only need 1 cup of cooked macaroni to make 2 servings.

Hi! The answer is 8 ounces of canned tomatoes and 1 cup of cooking macaroni.

This is because you want a quarter (1/4) of the servings so you only need a quarter of the ingredients and to get a quarter of something you just need to divide it by 4 so

32 / 4 = 8

4 / 4 = 1

Hope this helps:)

Answer:

9%

Step-by-step explanation:

10kg=R 20

5kg= R 15

??kg=R22

You add kgs it gives you 15kg and the and money it will give you R35 then

15kg=R35

???=R22

22/35×15 = 9,428571429

In a clinical trial of 268 subjects treated with a​ drug, 11​% of the subjects reported dizziness. The margin of error is plus o
Mariulka [41]

Answer:

\hat p =0.11 represent the proportion estimated of subjects reported with dizziness

n = 268 represent the random sample selected

\hat q = 1-\hat p = 1-0.11= 0.89 represent the proportion of subjects No reported with dizziness

E= 0.04 = 4% represent the margin of error for the confidence interval

\alpha= 1-0.90 =0.1 and this value represent the significance level of the test or the probability of error type I

Step-by-step explanation:

Previous concepts

A confidence interval is "a range of values that’s likely to include a population value with a certain degree of confidence. It is often expressed a % whereby a population means lies between an upper and lower interval".  

The margin of error is the range of values below and above the sample statistic in a confidence interval.  

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".  

The population proportion have the following distribution

p \sim N(p,\sqrt{\frac{p(1-p)}{n}})

Solution to the problem

The confidence interval for the mean is given by the following formula:  

\hat p \pm z_{\alpha/2}\sqrt{\frac{\hat p (1-\hat p)}{n}}

The margin of error is given by:

ME= z_{\alpha/2}\sqrt{\frac{\hat p (1-\hat p)}{n}}

Lower= 0.11-0.04 = 0.07

Upper= 0.11+0.04 = 0.15

And for this case we have the following info:

\hat p =0.11 represent the proportion estimated of subjects reported with dizziness

n = 268 represent the random sample selected

\hat q = 1-\hat p = 1-0.11= 0.89 represent the proportion of subjects No reported with dizziness

E= 0.04 = 4% represent the margin of error for the confidence interval

\alpha= 1-0.90 =0.1 and this value represent the significance level of the test or the probability of error type I

Find the area of the composite figure.
Tanzania [10]

Answer:

90 m

Step-by-step explanation:

The piece on the right side fits perfectly in the left side so you can move the triangle to the left in order to make a square. After that, you can do 10 times 9 because 5+4=9 to get 90m as the area.
