Answer is
<span>g(x) = 2.5x + 25
</span>5 newspapers, 2.5(5) + 25 = 12.5 + 25 = 37.5
20 newspapers, 2.5(20) + 25 = 50 + 25 = 75
Let x represent gallons of $19 paint
let y represent gallons of $3 paint
first you make your 2 equations
x+y=16, y=16-x
(19x+3y) ÷ 16 = 14
then you use substitution
14 = (19x + 3(16-x) ) ÷16
224 = 19x + 48 - 3x
176 = 16x
11 = x, so there's 11 gallons of $19 paint
recall that x+y=16
11+y=16
5=y
so there are 11 gallons of $19 paint and 5 gallons of $3 paint
C.
Because the given condition required to have a flower garden first and then the probability of having a vegetable garden is calculated.
Answer: The correct option is d
Step-by-step explanation:
Standard error measures how far the sample mean is from the population mean.
The formula for determining the standard error of the distribution of difference in means is expressed as
Standard error = √(s1²/n1 + s2²/n2)
where
s1 = sample 1 standard deviation
s2 = sample 2 standard deviation
n1 = number of samples 1
n2 = number of samples 2
From the information given
s1 = 2 pounds
n1 = 43 pounds
s2 = 1.7 pounds
n2 = 40 pounds
Standard error = √(2²/43 + 1.7²/40)
