Answer:
Option d) 840
Step-by-step explanation:
Given that a test to measure psychotic tendencies was given to a group of 1,000 air force cadets who wished to work in nuclear silos.
If Score ≥64 would be eliminated.
X is N(52, 12)
Probability for any random person to get eliminated
=
Now coming to sample size of 1000 people, we find each person is independent of the other and there are two outcomes either >64 or < 64
So Y no of persons who get more than 64 is binomial with n =1000 and p = 0.1587
Mean of Y = E(Y)
= no of people who were not accepted
No of people accepted
Approximately we get 840 so option d
Hi there! :)
Answer:
y = -2x + 3
Step-by-step explanation:
We can write an equation in slope-intercept form. Use the slope formula to find the rate of change in the table:
Plug in values from the table:
Simplify:
m = -2 (rate of change)
Use a point from the table (-2, 7) and the slope to solve for the equation for the linear function:
7 = -2(-2) + b
7 = 4 + b
7 -4 = b
b = 3
Rewrite:
y = -2x + 3 is the equation for the linear function.
Answer:
The answer is Y=0x+5 Please mark me brainliest :D
All 4 digit numbers beginning with 0, start with 0000 and end with 0999.
The first 100 numbers will always repeat, as they will have more than one 0
The first number will be 0123
From 0100 to 0100 there are no numbers possible
From 0101 to 0999, there are 7 numbers out of every 10 that could be an outcome, 700/1000 numbers are possible
There are 700 out of 1000 that could be outcomes
70%
