Answer:

Numbers are 9 and 5

Step-by-step explanation:

x + y = 14

x - y = 4

Rewrite 1st equation

x = 14 - y

Put this into the other

14 - y - y = 4

14 - 2y = 4

14 = 4 + 2y

10 = 2y

<u>y = 5</u>

<u />

x + y  = 14

x + 5 = 14

<u>x = 9</u>

<u />

<u>Check answers both equations!!</u>

9 + 5 = 14 Correct

9 - 5 = 4 Correct

Name the property the equation illustrates. 8 + 5.3 = 5.3 + 8
VMariaS [17]
The answer to the question is letter "D. Commutative Property of Addition". The property states that if there are two numbers which we may represent by a and b, the value of a + b is equal to the value of b + a. The given, 8 + 5.3 = 5.3 + 8 is an example of this property.

You recently took a statistics exam in a large class. The instructor tells the class that the scores were Normally distributed,
Lunna [17]

Answer:

b. the area to the right of 2

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean \mu and standard deviation \sigma, the zscore 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, which is also the area to the left of Z. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X, which is the area to the right of Z.

In this problem:

X = 96, \mu = 72, \sigma = 12

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

Z = \frac{96 - 72}{12}

Z = 2

Percentage who did better:

P(Z > 2), which is the area to the right of 2.
