Answer:

-1

Step-by-step explanation:

-1 (9-4) divided by 5. First you would subtract 9 by 4 to get 5, that would leave you with the equation -1 (5) divided by 5. Now -1(5) also means -1 multiplied by 5 and the answer to that would be -5, now your new equation is -5 divided by 5. Divide those and you get the answer of -1

What is meant by​ confounding?
ankoles [38]

Answer:

a)

Step-by-step explanation:

In a study, if we want to measure of establish a relation between two variables, we say that there is a confounding variable when there is a third variable that is having an effect on our original two variables but this third variable wasn't originally measured in our study. Therefore our results are misleading because the relation between our two variables is being influenced by the confounding one.

This is why the correct answer would be the a) An explanatory variable has a great effect on a response variable. And this causes a misleading interpretation between the two variables.

What two numbers multiply to 16 and add to 4?
alukav5142 [94]

You said that (xy) = 16, and (x+y) = 4 .

From the second equation you can get [ x = 4 - y ],
then substitude that for 'x' in the first equation, and
finally, rearrange the first equation to read
                                                                   <u>x² - 4x + 16 = 0</u>

Don't even try to factor that quadratic equation.  Go straight
to the quadratic formula, and the two solutions you find are ...

         <em>x = 2 + i 2√3</em>
and
         <em>x = 2 - i 2√3</em> .

Those are the two number that do what you want.

There are no <u>real</u> numbers that can do it.

The entire output of a factory is produced on three machines. The three machines account for 20%, 30%, and 50% of the output, re
Sliva [168]

Answer: 0.20833

Step-by-step explanation:

This is a case of inverse probability.

We first determine the probability that an item is defective generally.

To do this we sum the possible options of having the item produced from the first machine and is defective or having the item produced by the second machine and is defective or having the item produced by the third machine and is defective.

Mathematically,this becomes :

(0.2 * 0.05) + (0.3 * 0.03) + (0.5 * 0.01)

0.01 + 0.009 + 0.005 = 0.024.

Probability an item is defective in general = 0.024

Probability a third machine produces a defective item = 0.5 * 0.01 = 0.005.

Hence, given that the item is defective, the probability that it was produced by the third machine becomes:

= (probability of the item being produced from the third machine and is defective) / (probability of the item being defective in general)

= 0.005/0.024

= 0.20833.

Sasha's bank account earns 4% simple interest. How much must she deposit in the account today if she wants it to be worth $1,000
Serhud [2]

If Sasha wants her account to be worth $1,000 in 5 years, then she must deposit $833.34.

<h3>What is simple interest?</h3>

Simple interest is a method of calculating interest on an amount for n period of time with a rate of interest of r. It is calculated with the help of the formula,

SI = PRT

where SI is the simple interest, P is the principal amount, R is the rate of interest, and T is the time period.

Sasha's bank account earns 4% simple interest. Therefore, if she wants it to be worth $1,000 in 5 years then the principal amount must be,

Account balance = PRT + P

$1,000 = P[(0.04×5)+1]

$1,000 = 1.2 P

P = $833.34

Hence, if Sasha wants her account to be worth $1,000 in 5 years, then she must deposit $833.34.
