What is the answer or solution-15-3p=6
murzikaleks [220]

Answer:

P = - 7

Step-by-step explanation:

To solve we must put all the literals (letters) on one side of the operation and all the free numbers on the other. To do this we are going to do the same operations on both sides of the equal sign

- 15 - 3p = 6

So, we are going to add 15 on both sides

- 15 - 3p + 15 = 6 + 15

- 3p = 21

We are goint to divide everything by -3

-3p/-3 = 21/-3

It result:

<h2>p = -7</h2><h2 />

We check as follows:

We are going to replace the unknown (p) by the value we gave it already (-7)

-15 - 3(-7) = 6

-3 × -7 = +21

-15 + 21 = 6

6 = 6

we have the correct result

A university is applying classification methods in order to identify alumni who may be interested in donating money. The univers
HACTEHA [7]

The accuracy in the research done by university is 0.81, sensitivity is 0.93, specificity is 0.81 and precision is 0.047.

Given sample size of 58205 and proportion of people donated 576. Cutoff is 0.5.

Probability is the chance of happening an event among all the events possible. It lies between 0 and 1.

TP=total people donated in sample, TN=total number of people,FP=donation,FN=No donation

Accuracy is calculated as under:

=(TP+TN)/(TP+TN+FP+FN)

=(268+23439)/(238+23439+5375+20)

=23707/29102

=0.81

Accuracy=0.81

Sensitivity is calculated as under:

=TP/(TP+FN)

=268/(268+20)

=268/288

=0.93

Precision is calculated as under:

=TP/(TP+FP)

=268/(268+5375)

=268/5643

=0.047

Their values are the probabilities in itself.

Hence accuracy is 0.81, sensitivity is 0.93, specificity is 0.81 and precision is 0.047.

What are th zeros of f(x)=x(x-8)
Andrews [41]
Hi there!

Let's solve this problem step by step!
The zeros of a function are the input values that produce an outcome of 0. To find this input values we must set up and solve an equation.

f(x) = x(x - 8)
Set up the equation

f(x) = 0 thus x(x - 8) = 0

Now use the rule AB = 0 gives A = 0 or B = 0. This rule basically means that if we have a product that equals 0, at least one of the factors must be 0.

Hence, we get the following:
x = 0 \: \: or \: \: x - 8 = 0

Finally add 8 to both sides in the right equation.
x = 0 \: \: or \: \: x = 8

The zeros of the function are 0 and 8.
~ Hope this helps you!
