Answer:
C) 1/4
Step-by-step explanation:
P(Y,Y) = 3/6 x 3/6 = 1/2 x 1/2 = 1/4
Answer:
x = 
Step-by-step explanation:
The question states that it is the square root of the sum of both n and 6. That means n and 6 are added first before square rooted. Between B and C, choose the answer that has the parenthesis around x and 6, like (x + 6).
Answer to the first question is A. X = 10 and y = -2. Plug it into the equation.
-2 + 2 = 3/5(10 - 10)
0 = 0
Answer to the second question is A. It is going up "rise" by 4. And left "run" by -5
Answer to the third question is A. 2x will represent the slope. 5 will represent the y intercept.
Answer to the fourth question is C.
Answer to the last question is B. y = 5(1) y = 5. y = 5(0) y = 0.
Hope that helps
Answer: the probability that fewer than 100 in a random sample of 818 men are bald is 0.9830
Step-by-step explanation:
Given that;
p = 10% = 0.1
so let q = 1 - p = 1 - 0.1 = 0.9
n = 818
μ = np = 818 × 0.1 = 81.8
α = √(npq) = √( 818 × 0.1 × 0.9 ) = √73.62 = 8.58
Now to find P( x < 100)
we say;
Z = (X-μ / α) = ((100-81.8) / 8.58) = 18.2 / 8.58 = 2.12
P(x<100) = P(z < 2.12)
from z-score table
P(z < 2.12) = 0.9830
Therefore the probability that fewer than 100 in a random sample of 818 men are bald is 0.9830
Answer:
The rate of change will be the number of bags Fred fills for 1 customer.
Write a ratio.
21 : 3
x : 1
To solve for x, cross multiply.
3x : 21
Divide both sides by 3.
x = 7
Fred’s average rate of change is 7 bags.
