Answer:
X elevated to 21/25
Step-by-step explanation:
Exponent law say you have to multiplied the exponents:
(3/5)*(7/5) =
21/25
The mistake was using sumatory instead multiplication.

Somewhat true but I need more information to this problem
Answer:
1.16
Step-by-step explanation:
Given that;
For some positive value of Z, the probability that a standardized normal variable is between 0 and Z is 0.3770.
This implies that:
P(0<Z<z) = 0.3770
P(Z < z)-P(Z < 0) = 0.3770
P(Z < z) = 0.3770 + P(Z < 0)
From the standard normal tables , P(Z < 0) =0.5
P(Z < z) = 0.3770 + 0.5
P(Z < z) = 0.877
SO to determine the value of z for which it is equal to 0.877, we look at the
table of standard normal distribution and locate the probability value of 0.8770. we advance to the left until the first column is reached, we see that the value was 1.1. similarly, we did the same in the upward direction until the top row is reached, the value was 0.06. The intersection of the row and column values gives the area to the two tail of z. (i.e 1.1 + 0.06 =1.16)
therefore, P(Z ≤ 1.16 ) = 0.877
Answer:
B(2)
Step-by-step explanation:
SO basically think of it as x is a teenager that wants to be alone. so have to figure out how to get everyone on the otehr side of their bedroom door (>)
so you are going to do this
-1/2x>6
/-1/2x /-1/2x
x<6/-1/2
x<6*-2/1
x<-12
