Answer:
a.) 145°
Step-by-step explanation:
First, we need to understand that ∠5 = ∠4 because they are alternate interior angles, therefore, ∠5 = 35°. Then since ∠5 and ∠6 are supplementary angles, we know that ∠5 + ∠6 = 180°, therefore ∠6 = 180° - ∠5 = 180° - 35° = 145°. Now we need to understand that ∠6 and ∠7 are vertical angles, therefore they are equal to each other, so now we know that the right answer is a.) ∠7 = 145°.

The table shows the game scores of five players. Andy’s brother, Kevin, also plays and gets a score of 9. Find the mean, median, and mode of the data in the table. Then, find the mean, median, and mode of the data in the table and Kevin’s score.
Answers
Answer:
The third one
Step-by-step explanation:
Median - Middle number in terms of value
Mode - outcome that appears the most
Mean - average ( add the numbers together and divide that by the amount of numbers )
Data without Kevins score
13, 21, 28, 9, 31
First let's find the mean
To find the mean we simply add the numbers up and divide that by the total amount of numbers ( there are 5 numbers )
13 + 21 + 28 + 9 + 31 = 102
102/5=20.4
So the mean without Kevins score is 20.4
Next let's find the mode
The mode is the number that appears the most
Looking at the data no number appears more than once so there is no mode
Finally let's find the median.
To make it easier to find let's list the numbers in order from least to greatest
9, 13 , 21 , 28, 31
We then go to the middle number ( which would be 21 )
The mode is 21
So for data without Kevins score the mean would be 20.4, the median would be 21 and the mode would be none
Now let's add in Kevin's score and repeat this process
Data with Kevin's score
13, 21, 28, 9, 31, 9
First let's find the mean
( Note that there is 6 numbers this time )
13 + 21 + 28 + 9 + 31 + 9 = 111
111/6 = 18.5
So mean with Kevin's score = 18.5
Next let's find the mode
The number 9 appears the most so the mode is 9
Finally let's find the mean
Once again let's list the numbers from least to greatest
9, 9, 13 , 21 , 28, 31
Because there is an even amount of numbers we will take the sum of the two middle numbers and divide that by 2
The two middle numbers would be 21 and 13
21 + 13 = 34
34/2=17
So median = 17
In the end we get the following
Without Kevins score
Mean = 20.4
Median = 21
Mode = none
With Kevin's score
Mean = 18.5
Median = 17
Mode = 9
This information corresponds with the third table
What method would I use? I am confused on how to solve it. [tex]9k^2+3=-20[/tex]
Answers
9k² + 3 + 20 = 0 [reverse the sign when you carry over]
9k² + 23 = 0 [add the 3 and 20]
solve as a quadratic eqn and you’ll get
k = 0-1.59861050777i
or
k = 0+1.59861050777i
since there’s an i in the answers, it means this equation has no solution (or in terms of graphs, does not intercept/touch the x-axis)

Mean
Median

Answers
Answer:
mean = 5
median = 4.5
mode = 4
Step-by-step explanation:
Mean :
n = 8
sum of all items = 4+6+5+4+4+5+4+8
= 10+9+9+12
= 19+ 21
= 40
so,
mean = sum of all items/ n
= 40/8
= 5
mean = 5
Median:
ascending order: 4,4,4,4,5,5,6,8
n = 8
md = (n+1)/2 the term
= (8+1)/2 th term
= 9/2 th term
= 4.5 th term
= (4th + 5th) / 2
= (4+5)/2
= 9/2
= 4.5
median = 4.5

here the highest frequency is 4 and 4 is corresponding to 4

The circumference of a circle is 19π in. What is the area, in square inches? Express your answer in terms of π.
Answers
Answer:
A = 90.25 pi in^2
Step-by-step explanation:
The circumference is given by
C = 2*pi*r
19pi = 2*pi*r
Divide each side by 2 pi
19pi / 2 pi = 2*pi*r/ 2pi
9.5 = r
The area is given by
A = pi r^2
A = pi ( 9.5)^2
A = 90.25 pi in^2
Answer:
The area of circle is 90.25 π inches².
Step-by-step explanation:
Given :-
Circumference of circle is 19 π in.
To Find :-
Area of circle
Solution :-
Firstly, we need to find radius of circle
Using formula
Circumference of circle = 2 π r
substitute the value
19 π inches = 2 π r
Divide each side by 2 π
19 π inches / 2 π = 2 π r / 2 π
9.5 inches = r
Now, Finding the area of circle
Using formula
Area of circle = π × r²
Where,
r, radius of circle = 9.5 inchesSubstitute the values
Area of circle = π × ( 9.5 inches)²
Evaluate the exponent
Area of circle = π × 90.25 inches ²
multiply ,we get
Area of circle = 90.25 inches²
Hence, the area of circle is 90.25 π inches².

a)
FBC is half the circle, so the angle would = 180.
180 - 135 = 45, so thats the angle between BC
its a vertical angle, so it would be the same on the other side, between FE
the only angle left is betweeen DC, so add them all up and minus by 360
360 - 306 = 54
b)
a triangle's angles add up to 180, so
49 + 70 = 119
180 - 119 = 61
since this is an inscribed angle that isnt connected to the center, the arc will be double the angle
so ? = 122
d)
5(8) = 40
40/4 = 10
x = 10
f)
the rest of the circle is 243 bc 360-117=243
243 - 177 = 126

If IK is the whole length of the line segment, then IJ + JK = IK.
IJ + JK = IK
(3x - 5) + (2x - 1) = (3x + 2)
3x + 2x - 5 - 1 = 3x + 2
5x - 6 = 3x + 2
2x - 6 = 2
2x = 8
x = 4
Now that we know the value of x, we can plug this value back into the expression for JK and evaluate.
JK = 2x - 1
JK = 2(4) - 1
JK = 8 - 1
JK = 7
Hope this helps!
This is because JK + IJ = IK which means 2x-1+3x-5=3x+2
When you simplify this you will get x=4
You then plug 4 into your equation for JK so 2(4)-1 which equals 7

Step-by-step explanation:
Given
[tex]\frac{1}{4}[/tex] x - [tex]\frac{1}{2}[/tex] y = 8
[tex]\frac{1}{2}[/tex] x + [tex]\frac{3}{4}[/tex] y = - 5
Multiply both equations through by 4 to clear the fractions
x - 2y = 32 → (1)
2x + 3y = - 20 → (2)
Multiplying (1) by - 2 and adding to (2) will eliminate the x- term
- 2x + 4y = - 64 → (3)
Add (2) and (3) term by term to eliminate x
0 + 7y = - 84
7y = - 84 ( divide both sides by 7 )
y = - 12
Substitute y = - 12 into either of the 2 equations and solve for x
Substituting into (1)
x - 2(- 12) = 32
x + 24 = 32 ( subtract 24 from both sides )
x = 8
solution is (8, - 12 )

Nishi invests £4700 at 6% interest per year. Work out how much she will have altogether after: 2 years- £ 5 years- £ 7 years- £ 10 years- £
Answers
Answer:
Step-by-step explanation:
To calculate the compound interest we want to multiply the amount of money (£4700) by the interest (6%) which would be the percentage multiplier!
To get the new amount we do:
Original amount × (percentage multiplier)ⁿ
The amount of years would be the indices.
For the first year:
£4700x1.06= £4982.
But we want to find out how much she will have altogether in different years.
So for two years:
£4700x1.03²= £5280.90 (rounded)
As you can see the amount of years will be the indices with the interest as our multiplier.
We do this again for 5 years and 10 years:
£4700x1.06⁵= £6289.70 (rounded)
£4700x1.06¹⁰=£8416.20 (rounded)

There are 5+48+22 = 75 hot drinks ordered. Of that total, 22 hot drinks are large.
The probability of getting a large drink, given it was a hot beverage, is 22/75 = 0.2933 approximately.
This converts to 29.33% and that rounds to 29%
