Which statement is true? Question 2 options: All parallelograms are rectangles. All rectangles are squares. All quadrilaterals a
alekssr [168]

For this case, we have that:

  • By definition, a rectangle is a parallelogram. So, we discard the first option.
  • On the other hand, we have that all rectangles can not be squares, since a square has all its sides equal, while the rectangle, poir definition, no.So, we discard the second option.
  • All quadrilaterals are not rectangles because there are other figures with four sides that are not necessarily rectangular. We discard the third option.
  • Finally, we have that all squares are rectangles. This statement is true since squares can be rectangles with pairs of equal sides.

Answer:

Option D

Sati [7]

Answer:

The expression 3p⁵ ₓ 8p³ / 2p can be simplified to 12p⁷.

Step-by-step explanation:

To simplify:

3p⁵ ₓ 8p³ / 2p

= (3 ₓ 8)(p⁵ ₓ p³) / 2p

= 24p⁸ / 2p

= 12p⁷

Answer is 5

Explanation:

To go from (-1,0) to (0,5) we have to go up 5 units and right one unit.

Rate of change means slope, which is change in y over change in x.
If our change in y is positive 5 and our change in x is positive one, we can put the rate of change as 5/1

This simplifies to 5.

Suppose that replacement times for washing machines are normally distributed with a mean of 9.4 years and a standard deviation o
Nezavi [6.7K]

Using the normal distribution, it is found that the replacement time that separates the top 18% from the bottom 82% is of 11.23 years.

<h3>Normal Probability Distribution</h3>

The z-score of a measure X of a normally distributed variable with mean \mu and standard deviation \sigma is given by:

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

  • The z-score measures how many standard deviations the measure is above or below the mean.
  • Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.

In this problem, the mean and the standard deviation are, respectively, given by \mu = 9.4, \sigma = 2.

The desired value is the 82nd percentile, which is X when Z = 0.915, hence:

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

0.915 = \frac{X - 9.4}{2}

X - 9.4 = 0.915(2)

X = 11.23

The replacement time that separates the top 18% from the bottom 82% is of 11.23 years.
