We need to add 100% to it so now it's: 106.5%

Now we need to change it to a decimal and we do that by moving the decimal two spaces to the left.

106.5 = 1.065

We now multiply 1.065 and $7.50

7.50 × 1.065 = 7.9875

We need to round it so now it's $7.99

Assume a random variable x is normally distributed with mean = 90 and standard deviation = 5. Find the indicated probability.
nikklg [1K]

Answer:

16%

Step-by-step explanation:

The indicated probability is actually the area under the standard normal curve to the left of the mean.  I used the function normalcdf( on my TI-83 Plus calculator to find this quantity:

normalcdf(-1000,85,90,5) = 0.1587.

Note #1:  This quantity (area / probability) is the area to the left of 85.

Note #2:  by the Empirical Rule, 68% of data lies within 1 s. d. of the mean, so the area between the mean (90) and the score (85) is half of 68%, or 34%.  Subtracting this from 50% (the area to the left of the mean), we get 16%, which is roughly equivalent to the 0.1587 we got earlier.

sammy [17]

Answer:

5) 9

6) 11 2/3

Step-by-step explanation:

Use the Pythagorean Theorem.

5)  a²+5.6²=10.6²

a²+31.36=112.36

a²=81

a=√81

a=9

6) a²+4²=12.3333²

a²+16=152.11111

a²=152.11111-16

a²=136.1111

a=√136.1111=11.6666
