Homemade applesauce is one of Jared's favorite foods, so he stocked up on 10 pounds of

Vanyuwa [196]

Answer:

<h2>5 quarts</h2>

Step-by-step explanation:

Let's think through this bit by bit.

<em>10 lbs * 16 oz/lb = 160 oz. of apples.</em>

In the proportion below, we can see we simply divide by 8, in terms of magnitude.

8 oz -> 1 cup

160 oz -> 160/8 -> 20 cup

20 cups! Is it the answer? NO! They're asking for it in units of <em>quarts, not cups.</em>

We must remember that 1 quart = 4 cups.

20 cups * 1/4 qt/cups = 5 quarts

A set of data items is normally distributed with a mean of 400 and a standard deviation of 60. Find the data item in this distri

Softa [21]

Answer:

The data item is $X = 580$

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the z-score of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

Mean of 400 and a standard deviation of 60.

This means that $\mu = 400, \sigma = 60$

z=3

We have to find X when Z = 3. So

$Z = \frac{X - \mu}{\sigma}$

$3 = \frac{X - 400}{60}$

$X - 400 = 3*60$

$X = 580$

The data item is $X = 580$

What is the answer please please help me

Part A: the answer is C. They only converted milligrams to grams instead of going to kilograms. There are 6 steps between milligrams and kilograms, so 25,000 should've been divided by 1,000,000.
Part B
9.58 kg+1.25 kg+0.025 kg = 10.855 kg
So the bag, water bottle, and sleeping bag weigh 0.145 kg less than 11 kg
