Given triangle JKL,write the coordinates of the vertices of a triangle J’K’L’ that result from a translation of triangle JKL two

sweet [91]

Step-by-step explanation:

since I don't have any data about the coordinates, I am simply calling them xj, yj, and xj' and yj'.

J = (xj, yj)

K = (xk, yk)

L = = (xl, yl)

a translation (shift) 2 units to the left just means, that the y coordinates regain the same, but the x coordinates are decreased ("to the left" = getting smaller) by 2.

J' = (xj - 2, yj)

K' = (xk - 2, yk)

L' = (xl - 2, yl)

The lengths of 3-inch nails manufactured on a machine are normally distributed with a mean of 3.0 inches and a standard deviatio

otez555 [7]

Using the normal distribution, it is found that 2.64% of all the nails produced by this machine are unusable.

In a normal distribution with mean $\mu$ and standard deviation $\sigma$ , the z-score of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

It measures how many standard deviations the measure is from the mean.

After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.

In this problem:

The mean is of 3 inches, hence $\mu = 3$ .

The standard deviation is of 0.009 inches, hence $\sigma = 0.009$ .

Nails that are more than 0.02 inches from the mean are unusable, hence:

$Z = \frac{0.02}{\sigma}$

$Z = \frac{0.02}{0.009}$

$Z = 2.22$

The proportion is P(|Z| > 2.22), which is 2 multiplied by the p-value of Z = -2.22.

Z = -2.22 has a p-value of 0.0132.

2 x 0.0132 = 0.0264

0.0264 x 100% = 2.64%

2.64% of all the nails produced by this machine are unusable.

Hardy's plant grows rapidly. It grows by 10cm every 2 years. How much taller will Hardy's plant be in 5 years?

Angelina_Jolie [31]

The answer is 25centimeters. This is the answer because you have to multiply 10cm by 5 years then divide that by 2 since it grows 10 cm every 2 years.
