Answer:

S(7, -37)

Step-by-step explanation:

Let the coordinates of point S be (x, y).

(14 + x)/2 = 7

14 + x = 14

x = 0

(21 + y)/2 = -8

21 + y = -16

y = -37

What is the answer to this
Arisa [49]

Answer:

x = 20, <S = 47 degrees, <P = 131 degrees

Step-by-step explanation:

27 + x + 119 + 63 + 3x + 71 = 360

4x + 280 = 360

4x = 80

x = 20

<S = 27 + x = 27 + 20 = 47 degrees

<P =  3x + 71 = 3(20) + 71 = 131 degrees

Which statement is true about f(x) = -6|x+5| - 2?
Y_Kistochka [10]
Some schools do this differently, but since I don’t have any of the answer choices I’ll show you how to

Factor: -6|x+5|-2

Factor out the two

2(-3|x+5|-1)

A researcher was testing the number of popcorn kernels that popped out of a mini bag of 100 kernels after being cooked for the s
Lelechka [254]

Answer:

The percentage of the bag that should have popped 96 kernels or more is 2.1%.

Step-by-step explanation:

The random variable <em>X</em> can be defined as the number of popcorn kernels that popped out of a mini bag.

The mean is, <em>μ</em> = 72 and the standard deviation is, <em>σ</em> = 12.

Assume that the population of the number of popcorn kernels that popped out of a mini bag follows a Normal distribution.

Compute the probability that a bag popped 96 kernels or more as follows:

Apply continuity correction:

P( X\geq 96)=P( X>96+0.50)

                 =P( X>96.50)\\=P(\frac{X-\mu}{\sigma}>\frac{96.50-72}{12})\\=P(Z>2.04)\\=1-P(Z

*Use a <em>z</em>-table.

The probability that a bag popped 96 kernels or more is 0.021.

The percentage is, 0.021 × 100 = 2.1%.

Thus, the percentage of the bag that should have popped 96 kernels or more is 2.1%.
