Answer:

-2

Step-by-step explanation:

2p+8= -2p

Subtract 8 from both sides:

2p+8-8= -2p -8

Simplify:

2p= -2p-8

Add -2p to each side:

2p+2p= -8

Simplify:

4p= -8

Divide by 4:

p= -2

This question is incomplete because it was not written properly

Complete Question

A teacher gave his class two quizzes. 80% of the class passed the first quiz, but only 60% of the class passed both quizzes. What percent of those who passed the first one passed the second quiz? (2 points)

a) 20%

b) 40%

c) 60%

d) 75%

Answer:

d) 75%

Step-by-step explanation:

We would be solving this question using conditional probability.

Let us represent the percentage of those who passed the first quiz as A = 80%

and

Those who passed the first quiz as B = unknown

Those who passed the first and second quiz as A and B = 60%

The formula for conditional probability is given as

P(B|A) = P(A and B) / P(A)

Where,

P(B|A) = the percent of those who passed the first one passed the second

Hence,

P(B|A) = 60/80

= 0.75

In percent form, 0.75 × 100 = 75%

Therefore, from the calculations above, 75% of those who passed the first quiz to also passed the second quiz.

WILL GIVE BRAINLIEST<br>What is the value of a in the problem 4a-3=D<br>explain answer
mixas84 [53]
In this case, you aren't going to get an integer for the value of a, but you can rearrange the equation to equal a.

4a-3=D       add 3 to both sides
4a=D+3      divide both sides by 4
a=(D+3)/4   here's your answer

Can someone please help me ASAP.....
tester [92]

We have to start with a number x, compute f(x), and then use this result as input for g(x)

When you give x as input to f, it returns -x^2-1:

x\mapsto f(x)-x^2-1

Now, g(x)=x+5 simply means that g will return its input plus five.

In this case, the input is f(x), so we have

g(f(x))=f(x)+5 = -x^2-1+5=-x^2+4
