Answer:

Step-by-step explanation:

Step 1 ) Convert 25%% to a decimal : 0.25

Step 2 ) Multiply that by amount (0.25×64=16.00)(0.25×64=16.00)

Step 3 ) Subtract from amount (64−16.00)=$48.00

Write a problem that requires multiplying two decimals to find the answer. The product must have two decimals places.

julsineya [31]

Answer:

3.5 * 6.7 = 23.45

Step-by-step explanation:

(I am assuming you know how to do 2-digit by 2-digit problem, but just in case you don't I am putting in how to do it.)

You would multiply the problem like a normal 2-digit by 2-digit problem.

- multiply the ones places (5*7=35)

- you bring the 3 of the 35 and put it above the other 3

- you then do 7*3=21+3 because you moved it.

-so the first part of the question would be 35*7=245

-you go below the 5 and put a zero because you dont need the ones place anymore.

-you then do the same thing but with the tens place instead.

- You would then get 35*6=210, but you can't forget the zero.

- you would then add 245+2100=2,345

- But don't forget the decimals. you have to add the decimals to the answer.

- you count how many numbers that are behing both numbers, in this case it would be two.

- you then put the decimal after the ones and tens place.

A data set includes 108 body temperatures of healthy adult humans having a mean of 98.3degrees°F and a standard deviation of 0.6

mylen [45]

<h2>Answer with explanation:</h2>

The confidence interval for population mean is given by :-

$\overline{x}\pm z_{\alpha/2}\dfrac{\sigma}{\sqrt{n}}$

Given : Sample size : n=106

Sample mean : $\overline{x}=98.3^{\circ}\ F$

Standard deviation : $\sigma= 0.69^{\circ}F$

Significance level : $\alpha: 1-0.99=0.01$

Critical value : $z_{\alpha/2}=2.576$

Then , 99% confidence interval estimate of the mean body temperature of all healthy humans will be :-

$98.3\pm (2.576)\dfrac{0.69}{\sqrt{106}}\\\\\approx98.3\pm0.173=(98.3-0.173,\ 98.3+0.173)=(98.127,\ 98.473)$

Since 98.6 is higher than the upper limit of the confidence interval (98.473), then this suggest that the mean body temperature could be lower then 98.6 degrees.

The best estimate of population mean is always the sample mean. $\mu=\overline{x}=98.3^{\circ}\ F$

I WILL GIVE BRAINLIEST PLEASE HELP!!!

luda_lava [24]

Answer:

Step-by-step explanation:

interchange x and y

y= 1/(x - 2)

x = 1 / (y - 2) Multiply both sides by y - 2

x(y - 2) = 1 Remove the brackets

xy - 2x = 1 Add x to both sides

xy = 1 + 2x Divide by x

y = (1 + 2x)/x

The brackets have been destroyed. The answer is as I've given it.

y = (1/x) + 2
