lesser x=
greater x =

Answers

Answer 1

Answer:

lesser x = -6

greater x = 12

Step-by-step explanation:

(x - 3)^2 - 81 = 0

(x - 3)^2 = 81

x - 3 = +/- 9

x - 3 = 9   or   x - 3 = -9

x = 12   or   x = -6

Brenda bought three time more black fabric than red fabric. She bought 72 inches of red fabric. If fabric costs 7.25 per yard, how much did Brenda spend on fabric

Answers

Answer:

$58 dollars

Step-by-step explanation:

Step 1: Find price of Red Fabric. So Brenda bougt 72 inches. So we convert that to amount of yards.(36 inches=1 yard). So the equation is 72/36=2 yards. Then do 7.25x2= $14.50 for red fabric.

Step 2: Find price of Black Fabric. So Brenda bought 3 times more the red favric. So she 216(72x3 is how I got the number). Now divide 216 by 36. That equals 6. So now do 7.25x6= $43.50

Step 3: Add the prices. So now add the price of the red and black fabric to find the answer. So $43.50 + $14.50= $58

Hence, the answer is $58 dollars.

Answer:

Step-by-step explanation:

They add up to 180. You have a 90 degree angle and a 68 degree angle.

Your equation is: 180-90-68=x

x=22

For what value of x is line / parallel to line m in this figure?

Answers

Answer:

132

Step-by-step explanation:

The angle with a measure of 48 degrees and the angle labeled "x" are supplementary angles. Supplementary angles add up to equal 180

This means that we can find the value of the missing angle by subtracting the measure of the known angle from 180

So x = 180 - 48

180 - 48 = 132

Hence, x = 132

For a 95% confidence interval what would the sample size need to be as it's most conservative to have a 2% margin of error

Answers

Answer:

The size of the sample 'n' = 2401

Step-by-step explanation:

Step:1

Given that the margin of error = 2 % = 0.02

The margin of error is determined by

              [tex]M.E = \frac{Z_{0.05} \sqrt{p(1-p)} }{\sqrt{n} }[/tex]

we know that the proportion

               [tex]\sqrt{p(1-p)} < \frac{1}{2}[/tex]

Step:2

The margin of error is determined by

              [tex]0.02 = \frac{1.96( \frac{1}{2} ) }{\sqrt{n} }[/tex]

              [tex]\sqrt{n} = \frac{1.96}{2 X 0.02}[/tex]

              √n  = 49

Squaring on both sides, we get

                n = 49 × 49

                n = 2401

Final answer:-

The size of the sample 'n' = 2401

Answer:

2) 39.76

Answer:

solution given;

let

AB=a

AC=b=30ft

AB=c=20ft

<A=115°

By using Cosine rule.

a²=b²+c²-2bc cos angle

a²=30²+20²-2*30*20 Cos 115°

a²=1807.1419

a=√[1807.1419]

a=42.51

Side A is 42.51ft.

Again

Answer:

15

Step-by-step explanation:

The fraction computed shows that the number of his next 20 free-throw attempts that you expect Vijay to miss is 15.

How to solve the fraction?

From the information given, Vijay missed 12 out of his last 16 free throws. The fraction missed will be:

= 12/16

= 3/4

Therefore, the number of his next 20 free-throw attempts that you expect Vijay to miss will be:

= 3/4 × 20

A) x + 2 y = 1
C) x - 2y = 10
B) x-1= 2
D) x – 2y=

Answers

Answer:

B)

Step-by-step explanation:

y-intercept = -2

slope = 1

in slope-intercept form the line would be:  y = x - 2

if we subtract 'x' from each side we get:

-x + y = -2

we don't want to leave 'x' as negative so we can multiply each term by -1 to get:

x - y = 2

Mekala has an MP3 player called the Jumble. The Jumble randomly selects a song for the user to listen to. Mekala's Jumble has 4 techno songs, 2 country songs, and 3 jazz songs on it. Mekala plans to listen to 270 songs.

Answers

Answer:

Mekala Jumble has 4 techno songs, 2 country songs, and3 jazz songs on it.

Ratio of techno songs,to country songs,to jazz songs= 4: 2 : 3

Whatever be total  number of songs, let the number of techno songs, country songs,and jazz songs be  4 x,  2 x, and  3 x.

Total number of songs that Mekala plans to Listen = 2 70

Then , 4 x + 2 x + 3 x= 270

9 x = 270

Dividing both sides by 9, we get

x = 30

So, Number of techno songs = 4 × 30= 120

Number of techno songs = 2 × 30= 60

Number of jazz songs = 3 × 30= 90

Option (b) b) Close to 60 country songs but probably not exactly 60 country songs  ,is true option regarding number of songs listen by Mekala.
