What is the area that she paints
Andre45 [30]
To determine this, we need to multiply 8 by 36 and 3 by 4 to get the total area.
8 x 36 = 288
3 x 4 = 12

Subtract the two to get the total area she is painting.
288-12 = 276
Your total area is 276 sq ft.
Your answer is D.)
I hope this helps!

4/7(21/8 x + 1/2) = -2(1/7 - 5/28x)<br> What is x in decimal form?
frez [133]

Answer:

x=1.22930

Step-by-step explanation:

47(218 x+12 ) =−2(17 −528 x)

Simplify 47(218 x+12 ) :    327(21x+4) 327(21x+4) =−2(17 −528 x)

Multiply both sides by 7(21x+4)

327(21x+4) · 7(21x+4)=−2(17 −528 x)· 7(21x+4)

Simplify, 32=−14(17 −528 x)(21x+4)

Solve  32=−14(17 −528 x)(21x+4):    x=32+4√589105 , x=32−4√589105 x=32+4√589105 , x=32−4√589105

I will use the binomial distrubion to find the probability.

\displaystyle&#10;P(A)=\binom{n}{k}p^k(1-p)^{n-k}

------------------------------------------------------

A - selecting a red checker exactly 7 times in 10 selections

n=7\\&#10;k=10

\displaystyle&#10;P(A)=\binom{10}{7}\cdot\left(\dfrac{12}{15}\right)^7\cdot\left(1-\dfrac{12}{15}\right)^{10-7}\\\\&#10;P(A)=\dfrac{10!}{7!3!}\cdot\left(\dfrac{4}{5}\right)^7\cdot\left(1-\dfrac{4}{5}\right)^3\\\\&#10;P(A)=\dfrac{8\cdot9\cdot10}{2\cdot3}\cdot\dfrac{16384}{78125}\cdot\left(\dfrac{1}{5}\right)^3\\\\&#10;P(A)=120\cdot\dfrac{16384}{78125}\cdot\dfrac{1}{125}\\\\&#10;P(A)=\dfrac{393216}{1953125}\approx0.2=20\%

<u />(x/6) + 42 + (2x/5) - (8x/3) - 19   

Change the denominators (numbers below the fraction bar to a to a common number for the three numbers: 6, 5, and 3... in other words to a number that is divisible by all three numbers)

(5x/30) + (12x/30) - (80x/30) + 23
(-63x/30) + 23
