I think it’s B because the total he could spend is 52.50, so it could be less than that or equal to that very amount. The passage directly says he spent 31.75 on a coat. The only thing it didn’t give you a clear number on was the shirts, but it gives you the price so you put the price and the variable “s” together because you don’t know have many shirt he got.

Assume X is normally distributed with a mean of 5 and a standard deviation of 2. Determine the value for x that solves each of t
mihalych1998 [28]

Answer:

U = 5

S = 4

1.) P(X>x) = 0.5

Prob = 1-0.5 = 0.5

We have z = 0, that is the z score with the probability of 0.5

X = u + z(s)

= 5+0*4

= 5

2.) 1-0.95 = 0.05

Z score having this probability

Z = -1.64

X = 5-1.64*4

= 5-6.56

= -1.56

3.) P(z<1.0) - p(X<x) = 0.2

0.841345-0.2 = .641345

We find the z score given this probability

Z= 0.36

X = 5+0.36*4

= 5+1.44

= 6.44

4.) P(X<x)-P(Z<-.5)

0.95 = p(X<x)-0.308538

p(X<x) = 0.308538 + 0.95

= 1.258538

There is no x value here, given that the probability is more than 1.

5. 1-0.99/2 = 0.005

We get the z score value

= -2.58

U - 5 = 5-5 = 0

-x = 0-2.58(4)

X = 10.32

Please help mei really need this here is the picture
ANTONII [103]

Answer:

The length is 7.2 feet.

Step-by-step explanation:

It is a ratio of 10:18. Therefore you can simplify the ratio to 18/10 or 1.8. This then becomes 4 (width) times 1.8, or 7.2 feet. :)
