Write an equation in slope intercept form that is perpendicular to 3x + 2y equals 12 and passes through the point (1,2)
Answer:
The equation is y = (2/3)x + (4/3).
Step-by-step explanation:
First, you have to change the equation into slope-intecept formula to find its gradient (slope) :
[tex]3x + 2y = 12[/tex]
[tex]2y = - 3x + 12[/tex]
[tex]y = - \frac{3}{2}x + 6[/tex]
Given that when a line is perpendicular to the other line, their slope value multiplied, will form -1. Next, we have to find the slope for line :
[tex]m1 \times m2 = - 1[/tex]
[tex] - \frac{3}{2} \times m2 = - 1[/tex]
[tex]m2 = - 1 \div - \frac{3}{2} [/tex]
[tex]m2 = \frac{2}{3} [/tex]
Lastly, we have to subatitute the x and y values into the equation, to find its intercept value :
[tex]y = \frac{2}{3}x + b[/tex]
[tex]let \: x = 1,y = 2[/tex]
[tex]2 = \frac{2}{3} (1) + b[/tex]
[tex]b = 2 - \frac{2}{3} [/tex]
[tex]b = \frac{4}{3} [/tex]
[tex]y = \frac{2}{3} x + \frac{4}{3} [/tex]

what is the solution to the equation 5/8(4x-16)=20
The solution of the expression will be;
⇒ x = 14
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The expression is,
⇒ 5/8 (4x - 16) = 20
Now,
Since, The expression is,
⇒ 5/8 (4x - 16) = 20
Solve for x as;
⇒ 5 (4x - 16) = 20 × 8
⇒ 4x - 16 = 20 × 8/5
⇒ 4x - 16 = 40
⇒ 4x = 40 + 16
⇒ 4x = 56
⇒ x = 14
Thus, The solution of the expression will be;
⇒ x = 14

what is 3f + 8f + 4f simplified?
Answer:
Step-by-step explanation:
Simplifying
3f + f + 4f = 0
Combine like terms: 3f + f = 4f
4f + 4f = 0
Combine like terms: 4f + 4f = 8f
8f = 0
Solving
8f = 0
Solving for variable 'f'.
Move all terms containing f to the left, all other terms to the right.
Divide each side by '8'.
f = 0
Simplifying
f = 0

A researcher collected data from male and female Caucasian, African American, and Hispanic graduate students using quantitative measurs of extraversion, academic self-efficacy, dissertation anxiety, and math anxiety, each on a scale of 0 to 100 with higher scores indicating more of the specific latent attribute (e.g., more anxiety). Each participant was also asked if they intended to conduct a qualitative or quantitative dissertation study and how many months they estimated it would take to finish the dissertation.
Dissertation anxiety and number of months to finish a dissertation are not related.
a. Correlation
b. Paired samples t test
c. Analysis of Variance (ANOVA)
d. Multiple linear regression
e. Chi square test of independence
Answer:
a. Correlation
Step-by-step explanation:
Correlation is the measure of the degree to which any two variables vary together.In simple words two variables are correlated if they vary simultaneously in some direction.
We have two variables here . One is the measure of anxiety and the other is the number of months.
Paired sample t- test is conducted when we have the paired data. So this option is incorrect.
ANOVA is used for determining the total partitions or total variations.
Multiple Linear regression is used for indpendent variables.
Chi square distribution contains only one variable .
So the correct answer is option a.

What is the highest common factor (HCF) of 72 and 96?
1
Answer:
HCF of 72 and 96 is 24
Step-by-step explanation:
What is the highest common factor (HCF) of 72 and 96
HCF
Highest Common factor(HCF) is the biggest number that is divisible by both numbers.
First we will write prime factors of both 72 and 96
72: 2x2x2x3x3
96: 2x2x2x2x2x3
Now, writing the common factors: 2x2x2x3
Multiplying them we get: 24
So, HCF of 72 and 96 is 24

If bcd~gef find value of x
Answer:
[tex]x = 13[/tex]
Step-by-step explanation:
Given
See attachment
Required
Find x
From the attachment, we have:
[tex]BC = x + 4[/tex]
[tex]BD = 2x - 7[/tex]
[tex]GE = 51[/tex]
[tex]GF = 57[/tex]
Because both triangles are similar, we use the following equivalent ratios:
[tex]BC : BD = GE : GF[/tex]
Substitute values for each parameter
[tex]x + 4 : 2x- 7 = 51 : 57[/tex]
Convert to fractions
[tex]\frac{x + 4}{2x- 7} = \frac{51 }{ 57}[/tex]
Simplify the right-hand side
[tex]\frac{x + 4}{2x- 7} = \frac{17}{19}[/tex]
Cross Multiply
[tex]19(x + 4) = 17(2x - 7)[/tex]
[tex]19x + 76 = 34x - 119[/tex]
Collect Like Terms
[tex]19x - 34x = -76 - 119[/tex]
[tex]-15x = -195[/tex]
Solve for x
[tex]x = \frac{-195}{-15}[/tex]
[tex]x = 13[/tex]
Answer: x=13
Step-by-step explanation:
:(x+4) 57 = (2x-7) 5157x + 228 = 102x - 357357+228 = 102x - 57x585 = 45x13 =

Mr. Kazadi said that in his 2nd-period class, 23 out of 25 students passed the test. What percent of the students passed the test?
%
[tex]\text{Hello there!}[/tex]
To find a percentage, you will need to divide both numbers by each other. In this case, it would look similar to this:
[tex]\text{23 / 25 = ???}[/tex]
Once you divide the two numbers, you should end up with a result of [tex]0.92[/tex]
Now, we are going to move the decimal two spaces to the right to end up with the result:
[tex]\text{092.}[/tex]
Now, we are going to remove the [tex]0[/tex] as it is no longer required. Next, add a percentage symbol to the last number, and remove the decimal from the number.
Now, you should end up with something like this:
[tex]92\%[/tex]
[tex]\fbox{So your final answer is going to be 92\%}[/tex]

A professor grades a set of exams and then computes the quartiles:
Q0 = 60. Q1 = 70. Q2 = 80 Q3 = 87. Q4 = 95
If the professor curves every grade up by 10 points, then how will Q2 be affected by the curve?
I. It will increase by 10 points
ii. It will be 10 points higher than the median for the noncurved data
III It will be halfway between Q1 and Q3 for the curved data
a. I only
b. II and III
c. I, II and III
d. I and II
e. I and III
Answer:
Answer is c. I, II and II
Step-by-step explanation:
Solution:
Answer is c. I, II and II
It will be increase by 10 points and it will be 10 points higher than the median for the noncurved data. and it will be halfway between Q1 and Q3 for the curved data.
Median for noncurved data = Q2 = 80
Median for curved data = 90
It will increase by 10 points = 90
It will be 10 points higher than the noncurved data = 90-80 = 10 points
if the set contains 20 values then, noncurved data will be:
60 _ _ _ _ 70 _ _ _ _ 80 _ _ _ _ 87 _ _ _ _ 95
Curved data will be: (all grades increased by 10 points)
70 _ _ _ _ 80 _ _ _ _ 90 _ _ _ _ 97 _ _ _ _ 105
Here, we can see median = Q2 = 90, exactly, halfway between Q1 =80 and Q3 = 97
Hence, C is the right answer

4. Liza wants to have more than $750 in her
savings account before she will leave for college.
Right now she has $300, and she is going to
babysit to earn $12.00 an hour. How
many
hours
will Liza need to babysit before she leaves for
college?
750 - 300 = 450
She needs to save $450 more.
$450 / $12 per hour = 37.5 hours
She needs to babysit 37.5 hours.
