$<span>1,241 is my answer. I used a calculator for interest, so I'm sure this is the correct answer. Rounding it to the nearest hundredth I suppose it would be $1,200. I'm not good at rounding, but I hope this has helped you some.</span>

a. Jan

f.Susan

d)

a. Jan: 140

b. Joel: 156

c. Juan: 196

d. Linda: 191

e. Robert: 183

f. Susan: 110

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, positive z-scores are above the mean, negative are below the mean and 0 is 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.

Question a:

Robert, Juan and Linda had positive z-scores, so they scored above the mean, and the correct options are c,d,e.

(b) Which of these students scored on the mean?

Joel, which had a z-score of 0, so the correct option is b.

(c) Which of these students scored below the mean?

Jan and Susan had negative z-scores, so them, options a and f.

Question d:

We have that $\mu = 156, \sigma = 24$ , so we have to find X for each student.

Jan:

Z = -0.65. So

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

$-0.65 = \frac{X - 156}{24}$

$X - 156 = -0.65*24$

$X = 140$

b. Joel

Z = 0, so:

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

$0 = \frac{X - 156}{24}$

$X - 156 = 0*24$

$X = 156$

c. Juan

Z = 1.66, so:

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

$1.66 = \frac{X - 156}{24}$

$X - 156 = 1.66*24$

$X = 196$

d. Linda

Z = 1.46. So

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

$1.46 = \frac{X - 156}{24}$

$X - 156 = 1.46*24$

$X = 191$

e. Robert

Z = 1.11. So

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

$1.11 = \frac{X - 156}{24}$

$X - 156 = 1.11*24$

$X = 183$

f. Susan

Z = -1.9. So

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

$-1.9 = \frac{X - 156}{24}$

$X - 156 = -1.9*24$

$X = 110$

Mark, Paul and Brian share some sweets in the ratio 3:4:2. Mark gets 27 sweets. How many sweets are there altogether.

Lelu [443]

Answer:

Hello!

~~~~~~~~~~~~~~~~~

Your answer would be x = 81

Step-by-step explanation:

given ratio = 3:4:2

sum of the terms of the ratio = 3+4+2=9

no. of sweets mark got = 27

3/9 × x =27

x = 81

no.of sweets paul got = 4/9 × 81 = 36

no. of sweets brian got = 2/9 ×81 = 18

total number of sweets = 81

So your answer would be x = 81

Hope this helped you!

Given that YX=YZ write an inequality that relates m

Westkost [7]

Answer:

C. m<XYA > m<ZYA.

Step-by-step explanation:

Since XY = YZ, as indicated in the information given, the angles opposite XY and YZ would also be of equal measure of degrees.

Thus, XA = 5. The angle opposite XA is m<XYA.

ZA = 3. The angle opposite ZA is m<ZYA.

Since XA > ZA, therefore,

m<XYA > m<ZYA.
