If we double the sum of the numbers x and -21, we get the number -100. What is x?
Step-by-step explanation:
2{x + (-21) }= –100
= 2x – 42 = –100
= 2x= –100 + 42
= 2x= –58
= x = –58/2
x= –29

A random sample of 17 hotels in Boston had an average nightly room rate of $165.40 with a sample standard deviation of $21.70. The critical value for a 98% confidence interval around this sample mean is ________.
Answer:
153.158 ; 177.642
Step-by-step explanation:
Given the following:
Sample mean (m) = 165.40
Sample standard deviation (s) = 21.70
Sample size (n) = 17
α = 98%
Confidence interval = m ± z(SE)
z at 98% = 2.326
SE = s/√n
SE = 21.70/√17 = 5.2630230
Hence,
Confidence interval = 165.40 ± 2.326(5.2630230)
165.40 - 12.241791498 OR 165.40 + 12.241791498
153.158 ; 177.642

Write an equation of the line passing through the point (8,-5) that is parallel to the line 2x – 6y=-3.
y = mx + b
Answer:
y=[tex]\frac{1}{3}\\[/tex]x - [tex]\frac{23}{3}[/tex]
Step-by-step explanation:
Ist put the first equation in y=mx+b form
2x-6y=-3
subtract 2x on both sides
2x-6y=-3
-2x =-2x
-6y=-2x-3
then divide both sides by -6
-6y=-2x-3
-6
that gives y=[tex]\frac{1}{3}[/tex]x+[tex]\frac{1}{2}[/tex] for the original equation
Then plug in the point and slope in y=mx+b
Use the same slope since the lines are parallel
(-5)=([tex]\frac{1}{3}[/tex])(8)+b
-5=[tex]\frac{8}{3}[/tex]+b
then subtract 8/3 on both sides and that gives
-23/3 = b
then you can make the new equation using -23/3 for you b and 1/3 for your slop m
How many times does three go into 35 m
Answer:
11 times
Step-by-step explanation:
35 divided by 3 = something like 11.6666666666. . .
That means that 3 only goes into 35 11 times since you don't count the 0.666666666. . .

We have the question...
How many times does 3 go into 35?
Well, this is pretty simple all you have to do is count up by 3s until you get to the number. Remember, it doesn't have to be exact though. So, here we go count by threes 11 times. We get 33 from 3*11. Therefore, your answer will be 11 times.

A day care center has 52 children. Each teacher has the same number of children. How many children could each teacher at the center have.
Answer:
The answer to this question would depend on how many teachers are available in the day care center.
If every teacher is to have the same number of children then the number of teachers will be factors of 52 which are more than 1;
2, 4, 13, 26, 52
If there are 2 teachers, each teacher will have 26 children
If there are 4 teachers, each teacher will have 13 children
If there are 13 teachers, each teacher will have 4 children
If there are 26 teachers, each teacher will have 2 children
If there are 56 teachers, each teacher will have 1 child

For f(x) = −2x + 12, find f(x) when x = −3.
Answer:
f(-3)= 18
Step-by-step explanation:
step 1: sub -3 in the equation f(x).
f(x)= -2x+12
f(-3)= -2×-3+12
step2: simplify to solve for f(-3).
=6+12
=18

Find the 15th term of the arithmetic sequence if the first term is -3 and the common difference is 2. Write the equation first, then substitute to find the answer
Answer:
25.
Step-by-step explanation:
f(x)=-3+2(x-1)
f(15)=-3+2(15-1)
f(15)=-3+2(14)
f(15)=-3+28
f(15)=25

Answer:
Kindly check explanation and attached picture
Step-by-step explanation:
Given the data:
Age(months) : 1 2 3 4 5 6 7 8 9 10 11 12
Weight (kg) : 4.3 5.1 5.7 6.3 6.8 7.1 7.2 7.2 7.2 7.2 7.5 7.8
a. Make a scatter plot of mean weight against age.
Scatter plot of mean weight against age can be found in the attached picture
b. Is there a positive or negative association between the two variables
There is a positive association between the weight and age variable ; as weight increases as age increases. Also the slope of the best fit line is positive

Graph the solution of the inequality 2x - (3 – x) > x + 1 on the number line.
Answer:
do multiply
Step-by-step explanation:
and take line in right side
The solution of the inequality 2x - (3 – x) > x + 1 is the values greater than 2. Therefore, option D is the correct answer.
The given inequality is 2x - (3 – x) > x + 1.
What is the solution of the inequality?A solution for an inequality in x is a number such that when we substitute that number for x we have a true statement.
Now, 2x - (3 – x) > x + 1 can be solved as follows:
2x -3+x>x+1 (Simplify the bracket)
⇒3x-3>x+1
Subtract x on both the sides of the inequality.
That is, 3x-3-x>x+1-x
⇒2x-3>1
Add 3 on both the sides of the inequality.
That is, 2x>4
Divide 2 on both the sides of the inequality.
That is, 2x÷2>4÷2
⇒ x > 2
The solution of the inequality 2x - (3 – x) > x + 1 is the values greater than 2. Therefore, option D is the correct answer.
