Y + 4 + 3(y+2) first distribute the 3
y + 4 + 3y + 6 then add like terms
4y + 10
therefore your answer should be 4y + 10

Answer:
0.03593
Step-by-step explanation:
We solve using z score formula
z = (x-μ)/σ, where
x is the raw score = 17,340
μ is the population mean = 15,000
σ is the population standard deviation = 1300
z score:
z = 17340 - 15000/1300
z =1.8
Probability value from Z-Table:
P(x<17340) = 0.96407
P(x >17340) = 1 - P(x<17340)
= 1 - 0.96407
= 0.03593
The probability that the life span of the monitor will be more than 17,340 hours is 0.03593
Answer:
25.1 in (nearest tenth)
Step-by-step explanation:
<u>Formula</u>
Circumference = πd (where d is the diameter)
From inspection of the diagram:
⇒ Circumference = 8π
= 25.1 in (nearest tenth)
Answer:
21,000 people preferred regular toothpaste
Step-by-step explanation:
28,000x1/4= 7000
7,000 people preferred baking soda toothpaste
