Write an 27, 31, 35, .... explicit formula for an, the n th term of the sequence
Answer :
See below ~
Explanation :
Common difference (d) between terms is :31 - 27 = 4Then the recursive formula is :
aₙ = aₙ₋₁ + 4Match y = 3x – 1 with its graph
Select the graph that matches the equation y = 8
5
10
x + 9.
Answer:
option C
Step-by-step explanation:
y = mx + b → y = 8.5x + 9
b is the y intercept: 9
m is the slope: 8.5
to identify this on the graph, the y intercept is when x = 0
crossing the vertical bold (y) line
so which one is at 9? c is the only one at 9

A sequence is defined recursively by the formula f(n 1) = –2f(n). the first term of the sequence is –1.5. what is the next term in the sequence? –3.5 –3 0.5 3
Given that the first term of the sequence is –1.5, the next term of the sequence would be 3
How to determine the next term?The recursive function is given as:
f(n + 1) = -2f(n)
Substitute 1 for n
f(1 + 1) = -2f(1)
Evaluate
f(2) = -2f(1)
Given that the first term is -1.5, the equation becomes
f(2) = -2 * -1.5
Evaluate
f(2) = 3
Hence, the next term of the sequence is 3

The measures of the angles of a triangle are shown in the figure below solve for X
Answer:
29 degrees
Step-by-step explanation:
The interior angles of all triangles equals 180. We know already that we have 101 and 50 degrees. If we add that, we get 151. To find x, we have to simply subtract 151 from 180. If we do this, we get 29. x=29.

An experimental study involves the researcher seeking to affect the results on purpose. The given situation is an observational study.
What are surveys, experiments, and observational studies?Surveys are one type of observational study since the researchers have no control over the results. Statistical surveys collect data from a sample group in order to learn more about the overall population.The sample population being examined is measured, or surveyed, in observational research. The researcher watches the individuals and measures variables but makes no attempt to influence the population or intervene in the study.In contrast to an observational study, an experimental study involves the researcher seeking to affect the results on purpose. The objective is to find out what influence a certain therapy has on the result.Since the researcher needs to find if a certain medicine improves the symptoms of the flu, therefore, the objective is to find out what influence a certain therapy has on the result.

what time did she leave home?
Answer:
She left at 7:55
Step-by-step explanation:
She travels 150 miles at 50 miles an hour, it takes her 3 hours to get to stoke but she stopped for 20 minutes. Subtract 20 minutes from 11:15, and you get 10:55, then subtract 3 hours. You get 7:55. This means she left the house at 7:55.

I assume that you know what the question is asking to solve for.
The net profit margin for Korey's Comics is 42.5%.
Option A is the correct answer.
What is a profit?Profit is the difference between the selling price and the cost price.
We have,
Net profit margin is calculated by dividing net income by net sales and multiplying the result by 100 to get a percentage.
Net Profit Margin = (Net Income / Net Sales) x 100%
Substituting the given values.
Net Profit Margin = (1,850 / 4,350) x 100%
Net Profit Margin = 0.425 x 100%
Net Profit Margin = 42.5%
Therefore,
The net profit margin for Korey's Comics is 42.5%.

Answer:
x = 10
Step-by-step explanation:
The sum of the angles of a triangle is 180 degrees
6x-6 + 7x+1 +55 = 180
Combine like terms
13x+50=180
Subtract 50 from each side
13x+50-50=180-50
13x = 130
Divide by 13
13x/13 =130/13
x = 10
The answer is A!
From this, we will get the equation
(13x -5) + 55 = 180
+ 5 on both sides
13x + 55 = 185
-55 on both sides
13x = 130
Divide by 13 on both sides
x = 10

1. it has at least 10 values. 2. it has at least 3 values that are different. 3. it has a mean and median of 12.
Answer: 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17
Step-by-step explanation:
First, we can ensure that 12 is the median by putting it in the middle and putting the same amount of numbers to its left and right side. To make the values have a mean of 12, the easy why to do it is to subtrate one as you move to the left and add one as you move to the right, that way they will cancel each other out and keep the mean at 12. The answer has a total of 11 values, has more than 3 values that are different, and has a mean and median of 12.
7+8+9+10+11+12+13+14+15+16+17=132
132/11=12
There are 5 values to each side of 12, making 12 the median.

bag contains eight red marbles and
seven blue marbles. You randomly pick a
marble and then pick a second marble
without returning the marbles to the bag.
The first marble is red and the second
marble is blue.
The probability of getting first marble is red and the second
marble is blue is 4/15.
What is probability?
Probability is simply how likely something is to happen. Whenever we're unsure about the outcome of an event, we can talk about the probabilities of certain outcomes.
Given that:
Number of red marbles= 8
Number of blue marbles= 7
Total Number of marbles= 8+7 = 15 marbles.
P(red Marble) =[tex]\frac{8}{15}[/tex]
No replacement, now the total marbles = 14
P( blue marbles) = 7/14
Now, P( first marble is red and the second marble is blue.)
= 8/15*7/14
= 4/15
Hence, the probability of getting first marble is red and the second
marble is blue is 4/15.

The two dot plots below compare the forearm lengths of two groups of schoolchildren:
Two dot plots are shown one below the other. The title for the top dot plot is Forearm Length, Group A and the title for the bottom plot is Forearm Length, Group B. Below the line for each dot plot is written Length followed by inches in parentheses. There are markings from 11 to 14 on each line at intervals of one. For the top line there are 3 dots above the second mark, 4 dots above the third mark, and 3 dots above the fourth mark. For the bottom line there are 3 dots above the first mark, 5 dots above the second mark, and 2 dots above the third mark.
Based on visual inspection of the dot plots, which group appears to have the longer average forearm length?
Group B, because three children in the group have the least forearm length of 11 inches
Group A, because three children in the group have the least forearm length of 11 inches
Group A, because seven children have a forearm length longer than 12 inches
Group B, because two children have a forearm length longer than 12 inches
Using the dot plot, the correct option regarding the group that appears to have the longer average forearm length is:
Group A, because seven children have a forearm length longer than 12 inches
What does a dot plot show?A dot plot shows the number of times each measure appears in the data-set.
In this problem, Group A has 3 students with forearm length of 14 inches, while group B have none. Group A also has more students with forearm length of 13 inches, and less of 11 and 12(lower values). Hence the correct option is given by:
