I think it’s b because if you add all of them up, you get 23 (total) and you just put the amount of blue cars over it so 6/23 .

kvv77 [185]

The reportable square footage for Kinsey's home = 2150square feet.

The main floor of Kinsey's home is 1,425 square feet.

The upper level is 875 square feet with one unfinished bedroom that measures 150 square feet.

The finished basement is 1,425 square feet with 7.5-foot ceilings.

That means the square footage of the upper floor plus the main floor (minus the unfinished laundry area).

Kinsey should report square feet (1425+875- 150)

= 2150square feet.

Hence, The reportable square footage for Kinsey's home = 2150square feet.

The sum of two numbers is 13 and there difference is 5 what are the 2 numbers?
Zielflug [23.3K]
X + y = 13
x - y = 5

x = (13 - y)

(13-y) - y = 5

13 - 2y = 5
-2y = -8
y = 4

x - 4 = 5
x = 9

x=9, y = 4

a student either knows the answer or guesses. Let 3434 be the probability that he knows the answer and 1414 be the probability t
Arlecino [84]

Answer:    \dfrac{12}{13}

Step-by-step explanation:

Let A = he known the answer then A' = he guess the answer.

B = he answered it correctly

As per given , we have

P(A)=\dfrac{3}{4}\ \ ,\ \ P(A')=\dfrac{1}{4}

P(B|A)=1

P(B|A')=\dfrac{1}{4}

By Bayes theorem , we have

P(A|B)=\dfrac{P(B|A)P(A)}{P(B|A)P(A)+P(B|A')P(A')}\\\\ P(A|B)=\dfrac{1\times\dfrac{3}{4}}{1\times\dfrac{3}{4}+\dfrac{1}{4}\times\dfrac{1}{4}}\\\\= \dfrac{12}{13}

The probability that the student knows the answer given that he answered it correctly is  \dfrac{12}{13} .

Number 8 Please!!!!!<br> Thank You!!!
lbvjy [14]

Answer:

x = 2 + 5i√2 / 6 and x = 2 - 5i√2 / 6

Step-by-step explanation:

If this isn't right, I'm sorry. Also, you can put x = 2 ± 5i√2 /6 to make it shorter and not have two answers. Hope this helps :)

Katy used 3/4 of a 6 ft board for a science fair project. How many inches did she use?
adoni [48]
She used 54 inches. 3/4 is equal to .75 so you can find 3/4 of the board by taking the fool length and multiplying it by .75 so 6•.75=4.5. So 3/4 of the board is 4.5 ft. However, the answer has to be in inches so since there are 12 inches in a foot you multiply 4.5•12 and that gives you your answer:54 inches.
