Answer:
what I think it is it's -4
Answer:
n = 3
Step-by-step explanation:
6(8 - 2n) = 2n + 6
48 - 12n = 2n + 6
-12n - 2n = 6 - 48
-14n = -42
n = -42/-14
n = 3

Find the measure of the missing angle.
Answer: a=
Answer:
a = 60
Step-by-step explanation:
The two angles form a right angle so the add to 90 degrees
a+30 =90
Subtract 30 from each side
a = 90-30
a = 60
Answer:
Hello! answer: a = 60
Step-by-step explanation:
This is a complementary angle meaning it will add up to 90 degrees so...
90 - 30 = 60 therefore a = 60 hope that helps!

Finding the area of a triangle is stralghtforward if you know the length of the base and the helght of the triangle. But is it possible to
find the area of a triangle if you know only the coordinates of its vertices? In this task, you'll find out. Consider /_\ABC, whose vertices
are A(2, 1), B(3, 3), and C(1,6); let line segment AC represent the base of the triangle.
Part A
Find the equation of the line passing through B and perpendicular to AC.
Part B
Let the point of intersection of AC with the line you found in part A be point D. Find the coordinates of point B.
Part C
Use the distance formula to find the length of the base and the height of /_\ABC.
Part D
Find the area of /_\ABC.
Answer:
Step-by-step explanation:

Answer:
A. Nonlinear function
Step-by-step explanation:
No vertical line intersects the graph in more than one place, so it is a function (not a "relation").
The graph is not a straight line, so is not a linear function. It is a nonlinear function.
Answer:

Step-by-step explanation:
A linear function is a straight line, a nonlinear function is a curved line, and a relation is a relationship between two points on a graph, such as an equation.

Algebraically manipulating the formula I = Prt, find the principal (PV) deposited in a savings account which earned $11,000 in interest at a simple interest rate of
9.5% for 15 years to the nearest whole cent).
$7,312.07
$8,083.92
$7.719.30
$6,987.44
None of these choices are correct.
Answer: the required principal value is $7,719.30
Step-by-step explanation:
Given: Formula to calculate interest : I= Prt, P=principal value, r = rate of interest, t = time.
I = $11,000
r= 9.5% = 0.095
t= 15 years
Substitute in formula, we get
[tex]11000=(P)\times (0.095)\times(15)\\\\\Righatrrow\ P=\dfrac{11000}{0.095\times15}\approx\$7719.30[/tex]

Suppose aggressive behavior is the dependent variable in a regression model and the other variables are independent variables. Is there evidence of extreme Multicollinearity
Answer and explanation:
Multicollinearity happens when multiple independent variables are correlated and therefore it is hard to determine which independent variable has the most impact or is most significantly affecting the dependent variable. This could be a source of confusion as the coefficients become less reliable.
Extreme multicollinearity occurs when there is exaggerated standard errors or increased variance of coefficient estimates.
Which two steps could be taken to simplify the expression y/3 + 2 = 11?
Answer:
y = 27
Step-by-step explanation:
y/3 + 2 = 11
First subtract 2 from each side
y/3 + 2-2 = 11-2
y/3 = 9
Then multiply each side by 3
y/3 *3 = 9*3
y = 27
Answer:
Answer is below :)
Step-by-step explanation:
y/3 + 2 = 11 is the Expression
Only two steps:
step 1 = subtract 2 from both the sides
y/3 = 9
Step 2 = multiply 3 from both sides
y = 27

It is believed that students who begin studying for final exams a week before the test score differently than students who wait until the night before. Suppose you want to test specifically that students who study earlier have an average score that is less than the average score for students who wait to study. What are the hypotheses for this test if early studiers are group 1 and procrastinators are group 2
Answer:
H0 : μ1 = μ2
H0 : μ1 < μ2
Step-by-step explanation:
Given :
Early studiers, group 1, mean μ1
Late studiers, group 2 ; mean, μ2
To test the claim that students who study earlier have an average score that is less than the average score for students
The null hypothesis ; there is no difference in average score
H0 : μ1 = μ2
Alternative hypothesis is early studiers means is less than average score of late studiers
H0 : μ1 < μ2
to rent a car a company will charge customers a $50.00 fee and then $29.99 per day to rent a car. Which expression represents the total cost for n days to rent a car?
A= n+50.00+29.99n
B=n+29.99+50.00
C=50.00n+29.99
D=29.99n+50.00
Answer:
D
Step-by-step explanation:
Because n is the number of days and 29.99 is the cost per day.
Also, $50 is the fee so you add that too.

Methods of statistics show that if a vegetarian diet had no effect on blood pressure, there would be less than 1 chance in 100 of getting these results. Does the result have statistical significance? Why or why not? Does the result have practical significance?
Answer: hi your question is incomplete below is the complete question
answer:
The result has a statistical significance because from the results obtained from the sample of people whom followed vegetarian diet and the people whom followed non-vegetarian diet we can see the different effects on blood pressure.
The result has a practical significance because the large difference in mean values.
Step-by-step explanation:
Sample size = 85 followed a vegetarian diet
Period = 4 months,
Mean systolic blood pressure= 124 mmHg
Sample size = 75 followed non-vegetarian diet
Period = 4 months
Mean systolic Bp = 138 mmHg
Reasons/explanations
Given that p -value < 0.01 we will reject the null hypothesis
The result has a statistical significance because from the results obtained from the sample of people whom followed vegetarian diet and the people whom followed non-vegetarian diet we can see the different effects on blood pressure.
The result has a practical significance because the large difference in mean values.
Solve -3(2-5w)=9w+66 for w
Answer:
w = 12
Step-by-step explanation:
-3(2-5w) = 9w + 66
Complete the parenthesis:
-6 + 15w = 9w + 66
Switch the numbers and group them with like terms;
15w - 9w = 66 + 6
6w = 72
w = 12
