To get the number of standard deviation that 77 is from the mean, we get the z-score:
z-score is given by
z=(x-μ)/σ
where:
μ-mean
σ-standard deviation
thus the value of z from the information above is:
x=77
μ=58
σ=7
z=(77-58)/7=2.7143
Answer:
x = -4y

Answer:
the slope of the line=0/6
Step-by-step explanation:
you can use the formula `y-y/`x-x, where (-8,5)=(x,y) and (-2,5)=(`x,`y)
5-5/-2--8
5-5/-2+8
0/6
Therefore, the slope of the line=0/6

Step-by-step explanation:
Answer:
138.16 square feet
Step-by-step explanation:
The surface area of the cylinder consists of one rectangle and two circles.
1. The radius of the circle is 4 ft, then the area of the circle is
2. The width of the rectangle is 1.5 ft, the length of the rectangle is the circumference of the circle.
Find the circumference:
Hence,
3. The surface area of the cylinder is
