angle 6 and angle 7 form a linear pair . Twice the measure of angle 6 is twelve more than four times the measure of angle 7 . Find the measure of each angle
Answer:
m∠7 = 58°
m∠6 = 122°
Step-by-step explanation:
Linear Pairs add up to equal 180°.
Step 1: Define
m∠6 + m∠7 = 180°
2m∠6 = 4m∠7 + 12
Step 2: Rewrite systems of equations
I will set m∠6 = x and m∠7 to y
x + y = 180°
2x = 4y + 12
Step 3: Rewrite 2nd equation
2x = 2(2y + 6)
x = 2y + 6
Step 4: Use Substitution
2y + 6 + y = 180
3y + 6 = 180
3y = 174
y = 58°
Step 5: Find x by plugging y back into an original equation
x + 58 = 180
x = 122°
Step 6: Rewrite
x = m∠6
y = m∠7
m∠6 = 122°
m∠7 = 58°

A Statistics professor assigned 10 quizzes over the course of the semester. He wanted to see if there was a relationship between the total mark of all 10 quizzes and the final exam mark. There were 213 students who completed all the quizzes and wrote the final exam. The standard deviation of the total quiz marks was 15, and that of the final exam was 17. The correlation between the total quiz mark and the final exam was 0.61. Based on the least squares regression line fitted to the data of the 213 students, if a student scored 17 points above the mean of total quiz marks, then how many points above the mean on the final would you predict her final exam grade to be?
Answer:
Her final exam grade would be 11.7521 above the mean
Step-by-step explanation:
We have:
The number of students = 213
Standard deviation of total quiz = 15
Standard deviation of final exam = 17
Correlation = 0.61
0.61x17/15
= 0.6913
If the student scored 17 points above the mean of total quiz marks
17 x 0.6913
= 11.7521
Her final exam grade would be 11.7521 above the mean

The radius of a circle measures 15 ft. What is the circumference of the circle?
Use 3.14 for n, and do not round your answer. Be sure to include the correct unit in your answer
Answer:
[tex]\boxed {\tt 94.2 \ feet}[/tex]
Step-by-step explanation:
The circumference of a circle can be found using the following formula:
[tex]c= \pi d[/tex]
where d is the diameter. We are given the radius, so let's find the diameter.
The diameter is twice the radius.
[tex]d=2r[/tex]
The radius is 15 feet.
[tex]d= 2 * 15 \ ft[/tex]
Multiply.
[tex]d= 30 \ ft[/tex]
Now we know the diameter. Substitute 30 feet in for d.
[tex]c= \pi d[/tex]
[tex]c=\pi * 30 \ ft[/tex]
We are using 3.14 for pi, so substitute it in.
[tex]c=3.14 * 30 \ ft[/tex]
Multiply.
[tex]c= 94.2 \ ft[/tex]
The circumference of the circle is 94.2 feet.
We have formula for this type Questions
c = πdc = πd
Here:-d is the diameter.We have radius in the Question so we can easily find diameter.
According to Question:-The diameter is twice the radius.
=> d = 2rd = 2r
Also we know that the radius is 15 feet.
So:-=> d = 2 * 15 \ ftd
=> d = 2∗15 ft
On Calculation:-=> d = 30 \ ftd = 30 ft
=> c= \pi dc=πd
=> c=\pi * 30 \ ftc=π∗30 ft
=> c=3.14 * 30 \ ftc=3.14∗30 ft
=> c= 94.2 \ ftc=94.2 ft
Therefore:-The required answer is 94.2 feet.What is the correct meaning of the word gripe?

In △ABC, m∠CAB = 60°, AD is the angle bisector of ∠BAC with D ∈ BC
and AD = 8ft. Find the distances from point D to the sides of the triangle.
pls don't use trigonometry
Answer:The distances from D to the both sides(AB and AC) of the triangle are 4 ft.
explanation:
In the diagram below, ABC is a triangle in which ∠CAB = 60°
As, AD is the angle bisector of ∠CAB, that means ∠CAD = ∠DAB = 30°
The distance from D to side AC is DE and distance from D to side AB is DF. That means both ∠AED and ∠AFD are right angle.
Given that, the length of AD = 8 ft.
So, in right angle triangle AED.....
Also, in right angle triangle AFD....
So, the distances from D to the both sides(AB and AC) of the triangle are 4 ft.
The distance from point D to the sides of the triangle is 4 feet.
What is an angle bisector?An angle bisector is defined as a line that divides an angle into two equal angles.
Draw the given angle first, then cut it in half, and then draw the angle's bisector.
Given that
In △ABC, m∠CAB = 60°,
AD is the angle bisector of ∠BAC with D ∈ BC
and AD = 8ft.
Angle CAB is 60 degrees, and AD bisects it, so angles CAD and BAD are each 30 degrees.
Let E be the point on AB for which DE is perpendicular to AB.
Then triangle ADE is a 30-60-90 right triangle with hypotenuse 8;
⇒ sin30° = DE/AD
⇒ 1/2 = DE/8
⇒ DE = 4
So the short-leg DE has a length of 4.
But since DE is perpendicular to AB, that is the distance of D from side AB.
So the distance of point D from sides AB and AC is 4.
Thus, the distance from point D to the sides of the triangle is 4 feet.

A quality analyst wants to construct a sample mean chart for controlling a packaging process. He knows from past experience that whenever this process is in control, package weight is normally distributed with a mean of 20 ounces and a standard deviation of two ounces. Each day last week, he randomly selected four packages and weighed each: Day Weight (ounces) Monday 23 22 23 24 Tuesday 23 21 19 21 Wednesday 20 19 20 21 Thursday 18 19 20 19 Friday 18 20 22 20 What is the standard deviation of the sampling distribution of sample means for whenever this process is in control?
Answer:
1 ounce
Step-by-step explanation:
Given that :
mean = 20 ounces
standard deviation = 2 ounces
sample size = 4 ounces
The standard deviation of the sampling distribution = [tex]\dfrac{Standard \ deviation}{\sqrt{sample \ size}}[/tex]
= [tex]\dfrac{2}{\sqrt{4}}[/tex]
= 2/2

In the past, 49% of those taking a public accounting qualifying exam have passed the exam on their first try. Lately, with the availability of exam preparation books and tutoring sessions may have improved the likelihood of an individual's passing on his or her first try. In a sample of 281 recent applicants, 154 passed on their first attempt. Using the 0.10 level of significance, conduct the analysis to determine whether we can conclude that the proportions passing on their first try has increased. What is the test statistic value from the analysis?
Answer:
The test statistic Z = 2 < 2.576 at 0.10 level of significance
Null hypothesis is accepted
Step-by-step explanation:
Step(i):-
Given Population proportion P = 0.49
Q = 1 - P = 1 - 0.49 = 0.51
Given sample proportion
[tex]p^{-} = \frac{x}{n} = \frac{154}{281} = 0.548[/tex]
Level of significance = 0.10
Null hypothesis : H₀ : P = 0.49
Alternative Hypothesis :H₁: P≠ 0.49
Step(ii):-
Test statistic
[tex]Z = \frac{p^{-} -P}{\sqrt{\frac{PQ}{n} } }[/tex]
[tex]Z = \frac{0.548-0.49}{\sqrt{\frac{0.49 X 0.51}{281} } }[/tex]
Z = 2
The tabulated value = 2.576
The calculated value Z = 2 < 2.576 at 0.10 level of significance
Null hypothesis is accepted

Which graph is the solution to the inequality –3x − 6 > 9?
Answer:
See attachment
Step-by-step explanation:
First solve this like a normal equation:
-3x - 6 > 9
Add 6 to both sides:
-3x > 9 + 6
-3x > 15
Divide by -3 and remember to switch the inequality sign:
x < 15/(-3)
x < -5
Think about the graph of x = -5. It's a vertical line crossing the y-axis at x = -5. Now, we have x is less than -5. That means all the values less than -5 should be viable solutions. So, shade the part of the graph to the left of the vertical line.
Also, since we have x < -5 and not x ≤ -5, the line should be dotted.

Select each statement that is true for all polynomials
Answer: When two polynomials are multiplied, the product is always a
polynomial.
Step-by-step explanation:
The only true property for polynomials is the third options because when you do multiply polynomials, you can only get a polynomial.
For instance;
Multiply (5x – 6y) by (7x – 4y)
= (5x – 6y)(7x – 4y)
= 35x² - 20xy - 42xy + 24y²
= 35x² - 62xy + 24y²
The result is a polynomial.
The rest of the options will not always yield polynomials.

the sum of two numbers is 90. their difference is 28. what are the numbers?
Hey there! ☺
[tex]Answer:\boxed{59\text{ and }31}[/tex]
[tex]Explanation:[/tex]
The first number can be written as x. The two numbers have a difference of 28, so the other number can be written as x-28. The total sum of the two numbers is 90. This can be written as an equation:
[tex]x+x-28=90[/tex]
Add 28 to both sides to leave the variable by itself:
[tex]x+x-28+28=90+28\\x+x=118[/tex]
Add the two x's:
[tex]x+x=118\\2x=118[/tex]
Divide both sides by 2:
[tex]\frac{2x}{2} =\frac{118}{2} \\x=59[/tex]
The first number is 59. The other number can be found by subtracting 28 from 59, since the difference between the two numbers is 28.
[tex]59-28=31[/tex]
To make sure the answer is correct, you can try adding the two numbers to check if they equal 90.
[tex]59+31=90\ \checkmark[/tex]
The answer is 59 and 31.
Hope this helps! ☺
