There are infinite amount of solutions and you can not determine prices of either. So 3 and 6.

Answer:

There are infinite solutions because they are the same equation

2D + 1G = 12

and

4D + 2G = 24 (divide by 2) 2D + G = 12

2D + 1G = 12 is the same as 2D + 1G = 12

The physical plant at the main campus of a large state university recieves daily requests to replace florecent lightbulbs. The d
zaharov [31]

Answer:

P(61≤ X≤94) = 49.85%

Step-by-step explanation:

From the given information:

The mean of the bell shaped fluorescent light bulb μ = 61

The standard deviation σ = 11

The objective of this question is to determine the approximate percentage of light bulb replacement requests numbering between 61 and 94 i.e P(61≤ X≤94)

Using the empirical (68-95-99.7)rule ;

At 68% , the data lies between  μ - σ and μ + σ

i.e

61 - 11 and 61 + 11

50 and 72

At  95%, the data lies between  μ - 2σ and μ + 2σ

i.e

61 - 2(11) and 61 + 2(11)

61 - 22 and 61 +22

39   and   83

At 99.7%, the data lies between  μ - 3σ and μ + 3σ

i.e

61 - 3(11) and 61 + 3(11)

61 - 33 and 61 + 33

28   and   94

the probability equivalent to 94 is when  P(28≤ X≤94) =99.7%

This implies that ,

P(28≤ X≤94) + P(61≤ X≤94) = 99.7%

P(28≤ X≤94) = P(61≤ X≤94) = 99.7 %    

This is so because the distribution is symmetric about the mean

P(61≤ X≤94) = 99.7 %/2

P(61≤ X≤94) = 49.85%

What is the area of this trapezoid?
Sonja [21]

Answer:

\boxed{Area \: of \: trapezoid = 126 \: {in}^{2}}

Given:

AB = 12 in.

DF = 2 in.

FE = 12 in.

EC = 2 in.

BE = 9 in.

Step-by-step explanation:

Area \: of \: trapezoid =  \frac{1}{2} (sum \: of \: parallel \: sides) \times height

Parallel sides are:

AB = 12 in

DC = DF + FE + EC

= 2 + 12 + 2

= 16 in.

Height:

BE = 9 in.

Area \: of \: trapezoid =  \frac{1}{2}(12 + 16) \times 9 \\  \\  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:   =  \frac{1}{2 }   \times 28 \times 9 \\  \\  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:   = 14  \times 9 \\  \\  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:   = 126  \: {in}^{2}

Anyone know how to do this?
juin [17]

Answer:

Gonna say B

Step-by-step explanation:

-0.01 (65)+110 = 109.35

It was the predicted value of the 65 year old's vision score.

Since the equation has an equal sign

y (=)

And not more than nor less than, answer choices C and D are eliminated.

The exact value for the 65 year old's vision score is 102. So, A isn't right.

Prove if the test point (2,-3) is a solution to the system:4x+3y > -6x-3y < -9
RoseWind [281]

If the point (2,-3), then it must satisfy both inequalities.

Let's replace it with the first one

\begin{gathered} 4x+3y>-6 \\ 4\cdot2+3\cdot(-3)>-6 \\ 8-9>-6 \\ -1>-6 \end{gathered}

As you can observe, the test point satisfies the first inequality.

Let's evaluate the second one

\begin{gathered} x-3y

The test point doesn't satisfy the second inequality.

<h2>Hence, the test point is not a solution to the given system because it doesn't satisfy both inequalities.</h2>
