Answer:
Step-by-step explanation:
You are given the linear regression equation as y = -.36x + 12.6, where y is the wind chill and x is the wind speed. We are being asked for the wind chill when the wind speed is 22; therefore, we are being asked to plug in 22 for x and solve for y:
y = -.36(22) + 12.6 and
y = -7.92 + 12.6 so
y = 4.68F
Answer: The highest labor cost per hour that he can afford is $34
Step-by-step explanation:
Hi, to answer this question we simply have to solve the inequality:
4x + 260 < 400
4x < 400-260
4x < 140
x < 140/4
x < 35
Since x represents the labor cost per hour , The highest labor cost per hour that he can afford is $34 (using whole numbers, because x must be less than 35, not less or equal)

Answer:
Step-by-step explanation:
Let x be the normal body temperature
X is N(99, sigma)
Sample mean x bar = 98.2 and s = 0.63
Margin of error = Z critical * 0.63 = 1.95 *0.63 = 1.2285
It is safe since 1.5 <1.96 critical value of z at 95%
