Answer: 11x + 5y
Step-by-step explanation:
FInd the perimeter by adding all the expressions together.
4x + 5x + 2.8y + 2x + 2.2y Combine like terms
(4x + 5x + 2x) + (2.8y + 2.2y)
11x + 5y
Answer:
I'd say you had a better chance going 5:8
Hello! So if Toby makes 7$ an hour and every piece work he makes they pay him 8 cents. And he worked a total of 39 1/2 hours and assembles 203 pairs of sunglasses, First find the anwser to how much money he made in 39 1/2 hours, you multiply 7 by 39 1/2 and you get = 276.50$ dollars. Then 8x203 equals to = 1,624, Lastly you add them up together and you get = 1,900.5$ dollars.

Answer: the probability the mean weight will exceed 2.1 ounces is 0.09
Step-by-step explanation:
Let x be the random variable representing the amount of icing on a Cuppie Cake large cupcake. Since it is normally distributed and the population mean and population standard deviation are known, we would apply the formula,
z = (x - µ)/(σ/√n)
Where
x = sample mean
µ = population mean
σ = standard deviation
n = number of samples
From the information given,
µ = 2
σ = 0.3
n = 16
x = 2.1
the probability that the mean weight will exceed 2.1 ounces is expressed as
P(x ≥ 2.1)
For x = 2.1
z = (2.1 - 2)/(0.3/√16) = 1.33
We would determine the probability for the area above z = 1.33 from the normal distribution table. It would be
p = 1 - 0.91 = 0.09
P(x ≥ 2.1) = 0.09
