Answer:
Step-by-step explanation:
Apply the Pythagorean Theorem:
85^2 = 67^2 + h^2, where h is the height of the TV
Then 7225 = 4489 + h^2, or
h^2 = 2736, or h = +√2736 = 52.3 inches
The TV is 52.30 inches tall if the television is advertised as an 85-inch TV if the width of the TV is 67.
What is a right-angle triangle?It is defined as a triangle in which one angle is 90 degrees and the other two angles are acute angles. In a right-angled triangle, the name of the sides are hypotenuse, perpendicular, and base.
We have:
A certain television is advertised as a 85 inch TV
It means the diagonal length is 85 inches.
Width of the TV = 67 inches
Let's suppose the TV is x inches Tall
So from the Pythagoras theorem:
[tex]\rm 85^2 = x^2+67^2[/tex]
7225 = x² + 4489
x = 52.30 inches
Thus, the TV is 52.30 inches tall if the television is advertised as an 85-inch TV if the width of the TV is 67.

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
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

What is the area of this compound shape? I need a step-by-step answer.
Answer:
The area is 96cm²
Area 1
A= 2(L+w)
A= 2( 15+7)
A=2(22)
A=44cm²
Area 2
A=2(L+W)
A= 2(11+15)
A=2(26)
A=52cm²
Total area=52+44=96cm²

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.
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.

Write an exponential function in the form y=b^x that goes through the points (0,9) and (3,4608)
Answer:
y = 9 * bˣ
Step-by-step explanation:
y = a * bˣ
9 = a * b⁰ = a * 1
a = 9
4608 = 9 * b³
b³ = 512
b = 8
y = 9 * bˣ
10)
A) x + 2 y = 1
C) x - 2y = 10
B) x-1= 2
D) x – 2y=
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

what is the least common multiple of the two denominators 32 18 8 12
Answer:
288
Step-by-step explanation:
32 = 2 × 2 × 2 × 2 × 2
8 = 2 × 2 × 2
18 = 2 × 3 × 3
12 = 2 × 2 × 3
LCM(32, 8, 18, 12)
= 2 × 2 × 2 × 2 × 2 × 3 × 3
= 288
the length of a rectangle is twice its width if the perimeter of the rectangle is 72 inches, find its area.
length = 2 x width
permiter = length x width x 2
perimeter = 72
72 ÷ 2 = 36
36 = 1 length and 1 width
(2 x width) + width = 36
width = x
2x + x = 36
3x = 36
x = 12
width = 12
length = 2 x width = 2 x 12 = 24
so
width = 12
length = 24

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