Select all the terms that are like terms.
timama [110]

Answer:

-8 x2

1.25 x2

x2

Step-by-step explanation:

Like terms are those which have the same variable. For example x²= x ² but x³≠x² functions having the same variable are called like terms. Terms vary with the change in exponents.

-8 x2

1.25 x2

x2

These three are like terms because they have the same variable with the same exponent.

The following are not like terms. They are unlike terms each having a different variable with a different exponent.

5 yx2

-3.4 x3

4 x

5

Like terms         -8 x2       1.25 x2          x2

Unlike terms :5 yx2             -3.4 x3           4 x                   5

Assume that the heights of women are normally distributed with a mean of 64.9 inches and a standard deviation of 1.6 inches. Fin
bulgar [2K]

Answer:

Q3 = 65.98 inches.

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean \mu and standard deviation \sigma, the zscore of a measure X is given by:

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

The Z-score 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. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

Normally distributed with a mean of 64.9 inches and a standard deviation of 1.6 inches.

This means that \mu = 64.9, \sigma = 1.6

Find Q3, the third quartile that separates the bottom 75% from the top 25%.

This is X when Z has a pvalue of 0.75. So X when Z = 0.675.

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

0.675 = \frac{X - 64.9}{1.6}

X - 64.9 = 1.6*0.675

X = 65.98

Q3 = 65.98 inches.

Tresset [83]
If you would like to know what expression would show the length of the poster, you can calculate this using the following step:

Amanda's poster ... 0.85 meter long
Orlando's poster ... 0.55 meter less than 1 meter long: 1 meter - 0.55 meter = 0.45 meter
