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:
3 years ago
Step-by-step explanation:
let m be Musa's age and d be Dayo's age
let x be number of years ago
m = 47
d = 22
(m - x)(d - x) = 836
(47 - x)(22 - x) = 836
1034 - 69x + x² = 836
x² - 69x + 198 = 0
This is in standard from ax² + bx + c = 0
Factor to be (x+q)(x+p)=0
p*q = c = 198
p+q = b = -69
198 = (-3)*(-66)
(-3) + (-66) = -69
Factored form is:
(x - 66)(x - 3) = 0
Set each bracket to 0
x - 66 = 0
x = 66 <= This number is inadmissable because neither Musa nor Dayo reached age 66.
x - 3 = 0
x = 3
The product of their ages was 836 3 years ago.

Answer:
Michael took his 6th sip at 4 : 05
Step-by-step explanation:
Duration in which Michael takes a sip of water = 20 minutes
Therefore, he will take his sixth sip after (20 × 6) = 120 minutes Or after 2 hours
If he takes first sip of water at 3 : 05
Then he will take his sixth sip at ( 3 : 05 + 2 : 00)
Time at his sixth sip = 5 : 05
