Answer: 669
Step-by-step explanation:
Given, In a Gallup poll of randomly selected adults, 66% said that they worry about identity theft.
i.e. The proportion of adults said that they worry about identity theft. (p) = 0.66
Sample size : n= 1013
Then , Mean for the sampling distribution of sample proportion = <em>np</em>
= (1013) × (0.66)
= 668.58 ≈ 669 [Round to the nearest whole number]
Hence, the mean of those who do not worry about identify theft is closest to 669 .
(3x-4y)^2=9x^2-24x+16y^2
(3x-2)(9x^2+6x+4)=27x^3-8
It says decreasing so you have to turn it into a percent (.06%) and then sub tract that from 1. After that you put that into an equation.
Answer:
<u>Marcelino will have $7.50: his costs are more than his profits. </u>
Step-by-step explanation:
22.50 + 7.50 + 15.00
In total Marcelino spent $45 to make these balloons.
He wants to sell each balloon for $1.25.
If he sells the 30 balloons he bought for $1.25 he will make:
30 * 1.25 = $37.50... okay he made some money, BUT he spent $45 dollars for the items.
45 - 37.50 = $7.50, Marcelino made no profit... he still needs to make $7.50 to pay off his own costs.
