The two triangles are congruent to each other, meaning they’re proportional to each other but not equal.
The question is asking you to list the angles that are congruent to each other (when talking about angles and congruency, if two angles are congruent, they are equal) and the sides that are congruent to each other (as long as all sides are proportional to each other, they are congruent (Triangle ABC has side lengths of 1, 2, 3 and Triangle DEF has side lengths of 2, 4, 6; these two triangles are congruent))

Pearl uses 9.8 pints of blue paint and white paint to paint her bedroom walls. 2 5 of this amount is blue paint, and the rest is

Ratling [72]

Answer:

She use <u>5.88 pints</u> of white paint.

Step-by-step explanation:

Given:

Pearl uses 9.8 pints of blue paint and white paint to paint her bedroom walls. $\frac{2}{5}$ of this amount is blue paint, and the rest is white paint.

Now, to find the pints of white paint she use.

Pearl uses total pint of paint = 9.8 pints.

The amount of blue paint

= $\frac{2}{5}\ of\ 9.8\ pints.$

= $\frac{2}{5} \times 9.8$

= $\frac{19.6}{5}$

= $3.92\ pints.$

Thus, the amount of blue paint = 3.92 pints.

Now, to get the white paint we subtract the amount of blue paint from the total pint of paint:

$9.8-3.92\\\\=5.88\ pints.$

Therefore, she use 5.88 pints of white paint.

US consumers are increasingly using debit cards as a substitute for cash and checks. From a sample of 100 consumers, the average

scoray [572]

Answer:

A. Margin of error = 128.79

B. The 99% confidence interval for the population mean is (7661.21, 7918.79).

Step-by-step explanation:

We have to calculate a 99% confidence interval for the mean.

The population standard deviation is know and is σ=500.

The sample mean is M=7790.

The sample size is N=100.

As σ is known, the standard error of the mean (σM) is calculated as:

$\sigma_M=\dfrac{\sigma}{\sqrt{N}}=\dfrac{500}{\sqrt{100}}=\dfrac{500}{10}=50$

The z-value for a 99% confidence interval is z=2.576.

The margin of error (MOE) can be calculated as:

$MOE=z\cdot \sigma_M=2.576 \cdot 50=128.79$

Then, the lower and upper bounds of the confidence interval are:

$LL=M-t \cdot s_M = 7790-128.79=7661.21\\\\UL=M+t \cdot s_M = 7790+128.79=7918.79$

The 99% confidence interval for the population mean is (7661.21, 7918.79).
