Answer:

Answer is 904

Refer below.

Step-by-step explanation:

5650 total,

And 4:1 which adds up and make 5. So,

5x = 5650

x=5650/5

x=1130

As pichard part is 4:1 so his part is 4 overall the money so,

Richard got 4x = 4 × 1130 = 4520

4520 now dividing in 6:3:1

10a = 4520

A= 452

Wife amount is 3a = 3 ×452 = 1356

Son is 1a so its,

Son = 452

Minus= 1356 -452 = 904

Wife got 904 more than son

Answer:

3. \displaystyle 4,12

2. \displaystyle \: \: \: \: \: - \\ 0,46

1. \displaystyle 0,875

Step-by-step explanation:

3. Every 25 is worth 4, and since 3 by 4 is 12, 3⁄25 gets set to ",12", then attach the <em>whole number</em> [4] to it, giving you 4,12.

2. Every 15 is worth 6⅔, and since 7 by 6⅔ is 46⅔, moving the decimal mark twice to the <em>left</em> will give you the above answer, in <em>bar</em><em> </em><em>notation</em>, since it is a repeated decimal.

1. Every 8 is worth 12½, and since 7 by 12½ is 87½ [87,5], moving the decimal mark twice to the <em>left</em><em> </em>will give you 0,875.

I am joyous to assist you anytime.

A soup can has a 3 and one eighth in diameter and is 5 in tall. What is the area of the paper that will be used to make the labe
Mamont248 [21]

Answer: 49.09 cm2

Step-by-step explanation:

Hi, to answer this question we have to apply the next formulas:

Circumference of a circle = π x diameter = 3.14159x 3 1/8 = 9.81746 in

The circumference of the can is equal to the length of the rectangular label:

Surface area (S)= circumference(length) x height  

Replacing with the values given:

S = 9.81746 x 5 = 49.09 cm2

Feel free to ask for more if needed or if you did not understand something.

Which of the following scores has the better relative position ( as measured by the z score) a. A score of 53 on a test for whic
Kisachek [45]

Answer:

d. Cannot be determined with the information provided.

Step-by-step explanation:

Z-score:

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.

Finding the better relative position:

The score with the better relative position is the one with a higher z-score.

To find the z-score, the mean and the standard deviation is needed, and in this question, the standard deviation is not given, and thus, the correct answer is given by option d.
