Answers

1. 78 = 0.15x
78 / 0.15 = x
520 = x.....so 78 is 15% of 520

2. | 3x - 2 | = 8 | x + 1 | = 1

3x - 2 = 8 -(3x - 2) = 8 x + 1 = 1 -(x + 1) = 1
3x = 8 + 2 -3x + 2 = 8 x = 1 - 1 -x - 1 = 1
3x = 10 -3x = 6 x = 0 -x = 2
x = 10/3 x = -2 x = -2

ur answer is : x = -2

3. 3y - 4x + 5 = 0
3y = 4x - 5
y = 4/3x - 5/3
slope = 4/3

There are two college entrance exams that are often taken by students, Exam A and Exam B. The composite score on Exam A is approximately normally distributed with mean 20.5 and standard deviation 4.9. The composite score on Exam B is approximately normally distributed with mean 1022 and standard deviation 214. Suppose you scored 27 on Exam A and 1209 on Exam B. Which exam did you score better on? Justify your reasoning using the normal model.

Answers

Answer: Exam A

Step-by-step explanation:

We must analyze how far are you from the mean in both cases, where the "step" that we will use to measure is the standard deviation.

In exam A, the mean is 20.5 and the standard deviation is 4.9.

If you scored a 27; then you need to see:

20.5 + 4.9 = 25.4

20.5 + 4.9 + 4.9 = 30.3

So you are within two times the standard deviation (more than the mean).

In the B exam, the mean is 1022 and the standard deviation is 214, where you scored 1209.

1022 + 214 = 1236

So in this exam, you are by one standard deviation away from the media.

With this, you can see that you did score better in exam A.

Adina has a rectangular garden that measures 9 m wide by 13 m long. She wants to increase the area to 192 m2 by increasing the width and length by the
same amount. What will be the dimensions of the new garden?

Answers

Answer: 16 m by 12 m.

Step-by-step explanation:

Given: The length of garden l = 13 m

The width of the garden w= 9 m

The area of the rectangular garden is given by :-

$\text{Area}=l* w\n\Rightarrow\text{Area}=13*9\n\Rightarrow\text{Area}=117\ m^2$

It she wants to increase the garden, the dimensions of the new garden will be (13+x) m by (9+x) m , then according to the question we have :-

$(13+x)\cdot(9+x)=192\n\Rightarrow\ 117+x^2+22x=192\n\Rightarrow\ x^2+22x=75\n\Rightarrow\ x^2+22x-75=0\n\Rightarrow\ x^2+25x-3x-75=0\n\Rightarrow\ x(x+25)-3(x+25)=0\n\Rightarrow\ (x+25)(x-3)=0\n\Rightarrow\ x=-25\ x=3$

Since, $x\neq-25$

Hence, x=3

Therefore, the dimensions of the new garden will be (13+3) m by (9+3) m=16 m by 12 m.

A jar contains 4 red marbles, 4 green marbles, and 5 blue marbles.If we choose a marble, then another marble without putting the first one back in the jar, what is the probability that the first marble will be blue and the second will be green?

Answers

Answer:

20/156 or 5/39

Step-by-step explanation:

the first part of the equation will be:

5/13 (5 is how many blue and 13 is altogether)

the next part of this equation is the green marble. Because we didn't put the blue marble back, the next part of the equation will be:

4/12 (4 is how many green and 12 is altogether now that one blue was taken out)

and from there, you multiply 5/13 with 4/12, with will give you 20/156, or 5/39 if you simplify.

Eight oranges cost $1.00.How much will 5 dozen oranges cost?

Answers

1 dollar is to 8
1:8
so 5 dozen
1 dozen=12
5 dozen=12 times 5=60
1:8 and x:60
1/8=x/60
multiply both sides by 60
60/8=x
30/4=15/2=7.5=x
$7.50 is how much you pay

5x12=60 60 divided by 8=7.5
