Answer:
Step-by-step explanation:
list of prime numbers from 1-21
2,3,5,7,11,13,17,19
he has 21 students
the only numbers he can divide by is 3 and 7
21/3=7
21/7=3
1. 4(n+3)=16, n+3=4, n=1
2. m/4+3=24, m/4=21, m=84
1. three added to a number n implies n+3, 4 times that sum is 4 (n+3), to solve divide both sides by 4 then subtract three from both sides.
2. a number divided by 4 means n/4 adding it to three n/4+3, to solve subtract 3 from both sides then multiply both sides by 4
Answer:
1.
A) Graph the points (length is x, weight is y)
B) Find slope and substitute 75 for x value
c) the relationship between length and weight is... (define the slope)
d)
2.
a) draw line through (0,40) and (6,70)
b) First find the slope and put it into y=mx+b (i guess you know this). then put slope into slope int. form and yeah.
c) just put x as 18 and solve for y, monthly revenue.

I was too lazy so i just gave instructions in the answer. Follow them and you should be fine. Good Night.
Answer:
40.96
Step-by-step explanation:
x/10.24=4
times 10.24 on both sides
10.24 times 4
x=40.96
Answer:
i) P(X<33) = 0.9232
ii) P(X>26) = 0.001
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given that the mean of the Population = 30
Given that the standard deviation of the Population = 4
Let 'X' be the Normal distribution
<u>Step(ii):-</u>
i)
Given that the random variable X = 33
>0
P(X<33) = P( Z<1.5)
= 1- P(Z>1.5)
= 1 - ( 0.5 - A(1.5))
= 0.5 + 0.4232
P(X<33) = 0.9232
<u>Step(iii) :-</u>
Given that the random variable X = 26
>0
P(X>26) = P( Z>3.5)
= 0.5 - A(3.5)
= 0.5 - 0.4990
= 0.001
P(X>26) = 0.001
