In a sequence, the first term is 4 and the common
difference is 3. The fifth term of this sequence is
1) -11
2) -8
3) 16
4) 19
Answers
Answer:
16
Step-by-step explanation:
Apply the arithmetic series formula, with A=4, d=3 and n=5 as n represents the number of terms.
An = A+(n-1)d
This shows that: A5 = 4+ 4(3) = 16.
Fifth term of the arithmetic sequence is 16.
What is arithmetic sequence?"Arithmetic sequences are ordered sets of numbers that have a common difference between each consecutive term."
Given
First term a1 = 4
Common difference d = 3
n = 5
Formula to find fifth term in the arithmetic sequence
[tex]a_{5} = a_{1} +(n-1)d[/tex]
[tex]a_{5}= 4+(5-1)3[/tex]
[tex]a_{5}= 4+(4)3[/tex]
[tex]a_{5}= 4+12[/tex]
[tex]a_{5}= 16[/tex]
Hence, fifth term of the arithmetic sequence is 16.

A survey was done of 160 households to find out if they watch cable television, internet television, or
both. Of the 160 households, 109 watched cable television, 88 watched internet television, and 7
watched neither. If a household was selected randomly, what would be the probability that they
watched both cable and internet television?
1) 0.175
2) 0.275
3) 0.375
4) 0.475
Answers
Answer: 2) 0.275
Step-by-step explanation:
Total households = 160
Watch Cable TV: 109
Watch internet TV: 88
Watch neither: 7
We want to find the number that watch both of them.
Now, the total number of housholds that watch at least one thing is:
160 - 7 = 153.
Now, if we add the number that watch by cable and the number that watch by internet we have:
109 + 88 = 197
The difference is:
197 - 153 = 44
This means that we have 44 households that watch both things.
This is because we are counting those 44 in the 109 for cable and also in the 88 for internet (because they watch both) and this is why we have a surpass.
Then the number that watch both things is 44, then the probability that a random household watched both things is equal to:
P = 44/160 = 0.275
The correct option is 2

Answer:
point - slope form: y+1 =2(x+2)
slop - intercept form: y =2x +3
standard form : 2x -y = -3 or -2x+y = 3
Step-by-step explanation:
find slope from given points using slope formula y₂ -y₁ / x₂ -x₁
slope m =5-(-1)/1-(-2) =6/3 =2
point - slope form is y - y₁ =m (x - x₁) where x₁ and y₁ are coordinates of one of the given points so
y - (-1) = 2(x -(-2))
y+1 =2(x+2)
slop - intercept form is y =mx +b where m is a slope and b is y intercept
now if you rearrange y+1 =2(x+2) as y =......
y+1 =2(x+2) → y+1=2x+4 → y = 2x+4-1 → y =2x +3
standard form is Ax +By = C where A,B,C are numbers; then by rearranging the equation again, it will be
2x -y = -3
graphing is done by using slop - intercept form: y =2x +3

11. 760.38 +0.38
Exact Answer:
Estimate:
Answers
Answer
10) 36
11)2001
Step-by-step explanation:
Answer:
10. 36 (exact answer), 30 or 30.16 (estimated answer).
11. 2001 (exact answer), Undefined, or 1900 (estimated answer).
Step-by-step explanation:
For number 10, the exact answer is 36 and the estimated is 30 or 30.16. Why?
-To have the exact answer we have to divide 903.6 ÷ 25.1 = 36.
-To have the estimated answer we have to round 903.6 and 25.1, as 903.6 is close to 900 and not 1,000, and 25.1 is close to 30 and not to 20. The equation is 900 ÷ 30 = 30.
-To make sure that the exact answer is correct, we have to multiple 25.1 and 36 = 903.6.
-To make sure that the estimated answer is correct, we have to multiple 30 and 30 = 900.
-But there's a problem, they can be two answers for the estimated answer 1). 30, and 2). 36.16. Process: 904 ÷ 25 = 36.16. Why? As they are decimal points, it may be that we have to round them but not the whole number, but the question doesn't specify how we have to round them, so I'm not so clear about it.
For number 11, the exact answer is 2001 the estimated is 1900 or Undefined. Why?
-To have the exact answer we have to divide 760.38 ÷ 0.38 = 2001.
-To have the estimated answer for the undefined we have to round 760.38 and 0.38, as 760.38 is close to 800 and not to 700, and 0.38 is close to 0 (0.00) and not to 1 (1.00). The equation is 800 ÷ 0.00 = Undefined.
-To make sure that the exact answer is correct, we have to multiple 2001 and 0.38 = 760.38.
-But there's a problem, they can be two answers for the estimated answer 1). Undefined, and 2). 19. Process: 760 ÷ 0.40 = 1900. Why? As they are decimal points, it may be that we have to round them but not the whole number, but the question doesn't specify how we have to round them, so I'm not so clear about it.

The angle measure of 3 is 140 degrees.
4 and 3 may not be in congruent spots but 4 and 2 are. Remember two of these angles next to each other equal 180 degrees. If 2 is also 40 degrees than 180 - 40 = 140. Alternate angles are equal meaning 3 is 140 degrees.

Answer:
The angle of depression is found.
θ = 26.56°
Step-by-step explanation:
Let point A be the entrance of a Deli.
Let point C be the location of camera.
Let point B be the horizontal distance from entrance to the camera.
It forms a right angled triangle. where Base = 16 ft and Perpendicular = 8 ft.
Let θ be the angle of depression at point B which is always equal to the angle of elevation at point A.
Using tan θ

9) Add all the numbers and divide by the total number of numbers
10) Bimodal
Step-by-step explanation:
1)Use the data to calculate the mean. 24, 31, 12, 38, 12, 15 *
To calculate mean you add all the numbers up and divide by the total number of numbers.
[tex]\frac{24 + 31+12+38+12+15}{6} = 22[/tex]
2) Use the data to calculate the median. 24, 31, 12, 38, 12, 15 *
For median, arrange the numbers from lowest to largest
12, 12, 15, 24, 31, 38
use (n+1) / 2 to figure out which value is the median
(6+1) / 2 = 3.5 (median is in between the 3rd and 4th value)
(15+24) / 2 = 19.5
3) Use the data to calculate the range. 24, 31, 12, 38, 12, 15 *
Range is max value - min value
38 is max and 12 is min
38 - 12 = 26
4) Use the data to calculate the mode. 24, 31, 12, 38, 12, 15 *
Mode is the value that appears most frequently
In this case 12 appears 2 times, therefore it is the mode
5) the mode represents the number that appears the least *
False, mode is the number that appears the most
6) To calculate the range we use the highest and lowest number ? *
True
7) Average is another word for *
mean
8) the range indicates the middle number ? *
False, range is the max value - min value

Ishmail jogs around a track that is in the shape of a regular pentagon. One side of the pentagon is ¼ mile long. How far does Ishmail jog if he completes 6 laps around the track?
If the track was a hexagon, how far would Ishmail jog in 6 laps?
Answers
Answer:
Ishmail will jog 7 1/2=7.5 miles if he completes 6 laps around the track if the track is pentagon.
Ishmail will jog 9 miles if he completes 6 laps around the track, if the track is hexagon .
Step-by-step explanation:
length of one side of pentagon = 1/4 miles
we know that number of sides of pentagon = 5
thus, total length of pentagon = number of sides * length of one side of pentagon = 5* 1/4 = 5/4
If anyone takes 1 lap of pentagon he will travel 5/4 miles
then,If anyone takes 1*6 lap of pentagon he will travel (5/4)*6 miles
thus, in 6 laps 15/2 miles will be traveled.
Ishmail will jog 15/2 ( 7 1/2 )miles if he completes 6 laps around the track.
_______________________________________
we know that number of sides of hexagon = 6
thus, total length of hexagon = number of sides * length of one side of hexagon = 6*( 1/4) = 3/2 miles
If anyone takes 1 lap of hexagon he will travel 3/2 miles
then,If anyone takes 1*6 lap of hexagon he will travel (3/2)*6 miles
thus, in 6 laps, 9 miles will be traveled.
Ishmail will jog 9 miles if he completes 6 laps around the track.

The students in Mrs. Willow's reading class are all reading the same novel independently. Four students create a graph of their reading rates, in words per minute, as shown below.
Which student reads the fastest?
Answers
Answer:
Sarah.
Step-by-step explanation:
Do not be fooled by how sharp the incline is, all of these graphs are labeled at different increments on both the x and y axes.
We will now solve this problem by figuring out each student's words per minute by dividing their words read (y-axis) by their time (x-axis).
Since the graphs are all linear, meaning they are constant and will never change. No matter what point we use on either graph we will come to the same words per minute for that student. For the sake of this explanation I will use the last point on each graph.
Charlie: Charlie read 1,750 words in 10 minutes, meaning he read at 175 words per minute. 1,750 / 10 = 175
Riley: Riley read 10,000 words in 50 minutes, meaning she read at 200 words per minute. 10,000 / 50 = 200
Sarah: Sarah read 1,300 words in 6 minutes, meaning she read at 216.67 words per minute. 1,300 / 6 = 216.67
Mason: Mason read 1,000 words in 5 minutes, meaning he read at 200 words per minute. 1,000 / 5 = 200
In conclusion, Sarah reads the fastest at 216.67 words per minute!
