Whenever you have __% more of something and want to find the new value, first convert the percent to a decimal. Then multiply the original value by (1.00+that decimal).

You have 6480 kg of sugar. 75%=0.75. If you want 75% more sugar, you would want 6480*(1.00+0.75) = 6480*(1.75) = 11,340 kg of sugar.

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

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).

Find the distance between (5, 6) and (-9, -2)

kolbaska11 [484]

Answer:

So we must determine the distance between our two given points and that can be found using the distance formula $d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$ .

Plugging the values into the equation and solve

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

$d=\sqrt{(-9-5)^2+(-2-6)^2}$

$d=\sqrt{(-14)^2+(-8)^2}$

$d=\sqrt{196+64}$

$d=\sqrt{260}$

$d=16.125\ units$

Therefore, our final answer is that the distance is 16.125 units
