Answer:
A) In 4 hours the tempature would both be the same
B) The tempature then would be 3 degreees Fahrenheit
Step-by-step explanation:
SO for the first step just make a list
In my format
x (hour): Coldspit and Frostberg in temperature
1st hour: -4.5 and 15
2nd hour: -2 and 11
3rd hour: 0.5 and 7
4th hour: 3 and 3
Indirect material cost: y
explained by units produced: x
Linear regression. Cost estimation equation: y=mx+b
Constant: b=$15,640
Standard error of y estimate=$3,600
r^2=0.7704
Number of observations: n=22
x coeffient: m=11.25
Standard error of x coefficient=2.19
m=11.25, b=15,640 → y=11.25x+15,640
Answer: The cost estimation equation is y=11.25x+15,640
C. It would be around 2.33 yards per bracelet.
Answer:
A would be 13
So the full point would be (13,-3)
To evaluate the radius of the cone we proceed as follows:
V=1/3 πr²h
plugging in the values, v=88π, h=8 ft
step 1
88π1/3πr²(8)
step 2
88π=8/3πr²
step 3
divide both sides by π
88=8/3r²
multiply both sides by 3/(8)
88(3/8)=r²
step 4
simplify
33=r²
step 5
get the square root
r=√33
Thus the mistake that Fatima made was:
<span> In step 3, Fatima did not multiply 88 by the reciprocal of 8/3 </span>
