Answer:

( 2 , \frac{1}{2} )

Step-by-step explanation:

A(-2, 4) , B(6, -3)

\boxed{midpoint = ( \frac{x1 + x2}{2}, \frac{y1 + y2}{2})  }

Midpoint between points A and B

= ( \frac{ - 2 + 6}{2} , \frac{4 - 3}{2} )

= ( \frac{4}{2} , \frac{1}{2} )

= (2 , \frac{1}{2} )

Answer:

The midpoint between A and B is a point with coordinates (2, 0.5).

Step-by-step explanation:

The "y" coordinate of the midpoint will be equal to the sum of A's and B's y coordinates divided by 2,  and the x coordinate of the midpoint will be equal to the sum of A's and B's x coordinates divided by 2.

x coordinate of the midpoint = (6 - 2) / 2 = 4 / 2 = 2

y coordinates of the midpoint = (4 - 3) / 2 = 1 / 2 = 0.5

Therefore midpoint between A and B is a point with co0rdinates (2, 0.5).

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%.
