Answer:
Geographic Features of Ancient Greece
Step-by-step explanation:
Greece has all these attributes on the list
To do so you find the opposites of each number so it would be
2a-3b
Simple, since your equation is y=35x+45, it's quite simple to see what is the y-intercept.
It's written in y=mx+b form, the b being the y-intercept.
Thus, your y-intercept, is 45.
Answer: B = 100 - a^2
Solution:
Step 1: Substitute all the values that are given in the equation
that would be C = 25 and S = a
Step 2: when substituted the equation would be
B = 4 (25) - (a)^2
B = 100 - a^2 Would be the answer
Note: if there was a numerical value to s then the answer would be a number but since s=a so the answer has variable too.
Answer:
a) the probability of A students study for more than 10 hours per week
P(X>10) = 0.117
b) The probability that an student spends between 7 and 9 hour
P(7<x< 9) = 0.9522
Step-by-step explanation:
Step(I):-
Let 'X' be random variable of the normal distributed with a mean of 7.5 hours and standard deviation of 2.1 hours
mean of the Population is = 7.5 hours
standard deviation of the Population = 2.1 hours
Z = 1.1904
The probability of A students study for more than 10 hours per week
P(X>10) = 0.5-A(Z₁) = 0.5 -A(1.1904) = 0.5 - 0.3830 = 0.117
Step(ii):-
Put x=7
put x=9
The probability that an A student spends between 7 and 9 hour
P(7 < x< 9) = A(9) - A(7)
= 0.7142 +0.238
= 0.9522
