Answer:
1/4
Step-by-step explanation:
Answer: a) The probability is approximately = 0.5793
b) The probability is approximately=0.8810
Step-by-step explanation:
Given : Mean : 
Standard deviation : 
a) The formula for z -score :
Sample size = 1
For x= 63 in. ,
The p-value = 
Thus, the probability is approximately = 0.5793
b) Sample size = 35
For x= 63 ,
The p-value = 
Thus , the probability is approximately=0.8810.
Circumference = π * d
π=3.14
diameter = 6
3.14 * 6 = 18.84.
The answer is A.

Answer:
(2,-1)
y= -1
x= 2
Step-by-step explanation:
y= -2x+3
4x-3y=11
substitute the value of y into an equation
4x-3(-2x+3)=11
distribute by multiplying numbers in parenthesis by -3
4x+6x-9=11
add 4x to 6x
10x-9=11
add 9 from both sides
10x=20
divide both sides by 10
x=2
substitute the value of x into an equation
y= -2•2+3
multiply -2 to 2
y= -4+3
add -4 to 3 but 4 is negative, so subtract
y= -1
