Answer:

7.73cm^2

Step-by-step explanation:

The equation for area of a circle is a= pie r^2. Now plug in pie as 3.14 and you radius which would be 3 because the image is showing the diameter as 6 and radius is half the diameter. The equation is now a=3.14 x3x3. The area of the circle would be 28.27cm^2.

Now we must find the area of the square. To do this multiple the diameter which is 6 times itself. 6x6=36. The area of the square is 36cm^2.

Now subtract the square area from the circle area. 36 - 28.27 = 7.73. The left over plywood would be 7.73cm^2.

I hope this helps! If you have anymore questions feel free to ask! :D

The probability that a lab specimen contains high levels of contamination is 0.12. A group of 4 independent samples are checked.

sergiy2304 [10]

Answer:

0.5996 is the probability that none contain high levels of contamination.

Step-by-step explanation:

We are given the following information:

We treat lab specimen containing high levels of contamination as a success.

P( lab specimen containing high levels of contamination) = 0.12

Then the number of lab specimens follows a binomial distribution, where

$P(X=x) = \binom{n}{x}.p^x.(1-p)^{n-x}$

where n is the total number of observations, x is the number of success, p is the probability of success.

Now, we are given n = 4

We have to find the probability that none of the lab specimen consist of high level of contamination.

We have to evaluate:

$P(x = 0)\\= \binom{4}{0}(0.12)^0(1-0.12)^{(4-0)}\\= 0.5996$

0.5996 is the probability that none contain high levels of contamination.

Deidre bought a car in California. The price of the car was $32,000. California has an 8% sales tax. How much did Deidre pay for

MrRa [10]

Given:

Price of car = $32,000

Sales tax = 8%

To find:

The price of car including sales tax.

Solution:

We have,

Price of car = $32,000

Salas tax = 8%

Amount of sales tax = 8% of price of car

$\text{ Sales Tax}=\dfrac{8}{100}\times 32000$

$\text{Sales Tax}=2560$

Now,

Total price of car including tax = Price of car + Sales tax

$\text{Total price of car including tax}=32000+2560$

$\text{Total price of car including tax}=34560$

Therefore, the price of car including tax is $34560.

The owner of a grocery store finds she can sell about 982 gallons of milk in a week if she prices it at $2.99 per gallon. If she

julia-pushkina [17]

Answer:

g = -1110p +4300.9
804 gallons

Step-by-step explanation:

a) Price is the independent variable, so the data we are given can be written as ...

(price, gallons) = (2.99, 982) and (2.79, 1204)

Using the 2-point form of the equation for a line, we have ...

g = (g2 -g1)/(p2 -p1)(p -p1) +g1

g = (1204 -982)/(2.79 -2.99)(p -2.99) +982

g = -1110(p -2.99) +982 = -1110p +4300.9

g = -1110p +4300.9

b) When p = 3.15, the predicted sales volume is ...

g = -1110(3.15) +4300.9 = 804.4

Weekly sales are predicted to be 804 gallons at a price of $3.15.
