Answer:
H
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
3x + 2y = 19 ( subtract 3x from both sides )
2y = - 3x + 19 ( divide all terms by 2 )
y = - [tex]\frac{3}{2}[/tex] x + [tex]\frac{19}{2}[/tex] ← in slope- intercept form
with slope m = - [tex]\frac{3}{2}[/tex]
Given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{-\frac{3}{2} }[/tex] = [tex]\frac{2}{3}[/tex] → H

A recent survey suggests that 47% of all televisions are connected to the internet, 32% are voice controlled, and 22% are both connected to the internet and voice controlled. Suppose a television is selected at random and it is voice controlled. What is the probability that a randomly selected voice-controlled television is also connected to the internet?
A. 0.15
B. 0.47
C. 0.69
D. 0.79
Answers
Answer:
0.69
Step-by-step explanation:
Here, we want to find the probability that a randomly selected television is connected to the internet given that it is voice-controlled
let P(V) is the probability of selecting a voice controlled television
P(I) is the probability that a selected television is connected to the internet
So the probability we want to calculate according to Baye’s theorem will be;
P(I|V) = P(I n V)/P(V)
P( I n V) = 22%
P(V) = 32%
So the probability is;
22%/32% = 0.6875 which is approximately 0.69
Answer: 0.69

A number increased by three is the same as quadrupling that number increased by five all divided by four. What is le number?
Answers
Answer:
The number is infinity
Step-by-step explanation:
Let the unknown number be x
if the number increased by three, then we have;
x + 3
Also quadrupling that number increased by five all divided by four is expressed as;
(4x+5)/4
Equating bith expressions and calculating x;
x+3 = (4x+5)/4
cross multiply;
4(x+3) = 4x + 5
4x+12 = 4x + 5
4x-4x = 5 - 12
0x = -7
x = -7/0
x = ∞
Hence the number is infinity

5x + 1 = 6x - x
I need help on this problem may you help
Answers
Answer:
Step 1: Simplify both sides of the equation.
5x+1=6x−x
5x+1=6x+−x
5x+1=(6x+−x)(Combine Like Terms)
5x+1=5x
5x+1=5x
Step 2: Subtract 5x from both sides.
5x+1−5x=5x−5x
1=0
Step 3: Subtract 1 from both sides.
1−1=0−1
0=−1
Answer:
There are no solutions.
Step-by-step explanation:
Answer:
no solution
Step-by-step explanation:
Given
5x + 1 = 6x - x , that is
5x + 1 = 5x ( subtract 1 from both sides )
5x = 5x - 1 ( subtract 5x from both sides )
0 = - 1 ← not possible
This indicates the equation has no solution

Josh was packing to move to another office. He packed 3 2/5 boxes on Tuesday and 2 9/10 boxes on Wednesday. After everything was moved to his new office on Wednesday afternoon, he only found 4 1/4 boxes. How many boxes were missing?
Answers
Answer:
2 1/10 boxes were missing.
Step-by-step explanation:
It is given that,
Josh packed [tex]3\dfrac{2}{5}[/tex] boxes on Tuesday
Josh packed [tex]2\dfrac{9}{10}[/tex] boxes on Wednesday
After everything was moved to his new office on Wednesday afternoon, he only found [tex]4\dfrac{1}{4}[/tex] boxes.
We need to find the no of boxes that are missing.
Total no of boxes packed on Tuesday and Wednesday,
[tex]3\dfrac{2}{5}+2\dfrac{9}{10}\\\\=\dfrac{17}{5}+\dfrac{29}{10}\\\\=\dfrac{63}{10}[/tex]
Missing boxes :
[tex]M=\dfrac{17}{4}-\dfrac{63}{10}\\\\=\dfrac{41}{20}\\\\=2\dfrac{1}{20}[/tex]
Hence, 2 1/10 boxes were missing.

Answers
Answer:

Sean multiplied two numbers and the resulting product was an irrational number. If the first number was 7/3, which of the following could be the second number? Two apply. 3/7, 2pie, 1, square root of three
Answers
Answer: 2*pi and √3.
Step-by-step explanation:
We know that when we multiply a rational number different than zero and an irrational number, the product will be also an irrational number.
Then if one of the numbers for this case is 7/3 (A rational number), the other must be an irrational number.
The given options are:
3/7 (is a rational number, so this is not the correct option)
2*pi (pi is an irrational number, then 2*pi is also an irrational number)
Then (2*pi)*3/7 will be an irrational number.
1 (this is a rational number, then this is not the correct option)
√3 (This is an irrational number, then this will be a correct option)
Then the two correct options are:
2*pi and √3.
