Answer:
1020 students
Step-by-step explanation:
Given the trend line equation :
y = 0.1x + 18,
where y is the total number of staff members and x is the total number of students.
Using the equation, the predicted number of students in a school with 120 staffs ;
y = 120
y = 0.1x + 18
120 = 0.1x + 18
120 - 18 = 0.1x
102 = 0.1x
x = 102 / 0.1
= 1020 students
Eunice wanted to save up for a mountain bike that costs £250. She baby-sits each week for 6 hours for £2.75 an hour, and does a Saturday job that pays £27.50. She saves 3/4 of her weekly earnings. How many weeks will it take her to save enough to buy the bike?
Answer:
Approximately 2 weeks
Step-by-step explanation:
Given data
Cost of bike= £250
Assuming she works for 6 days
1.Babysitting
6*2.75=£16.5 per day
for 6 days
=16.5*6
=£99
2. Saturday Job
=£27.50
Total earnings for the week
=£27.50+£99
=£126.5 weekly
Hence it will take her
=250/126.5
=1.97 week
Approximately 2 weeks to save up the amount

Find the average rate of change of g(x) =-x²+2x+2 from x=2 to x = 6.
Simplify your answer as much as possible.
Solve the equation replacing x with 2 and the 6:
-2^2 + 2(2) + 2 = 4 + 4 + 2 =10
-6^2 + 2(6) + 2 = 36 + 12 + 2 = 50
Difference between the answers: 50-10 = 40
Difference between 2 and 6 = 6-2 = 4
Average rate of change = 40/4 = 10
The answer is 10

Step-by-step explanation:
the slope is the rise over the run from one point to another.
i hope this helps :)
Each line is 1 unit.
Use the dots A and B
A is located at (-3,3)
B is located at (3,-3)
Slope is the change in y over the change in x
Slope = (-3 -3) / (3 - -3)
Slope = -6/6
Slope = -1
The answer is D -1

find the area of the circle. round to the nearest tenth. please help and please show work!!!!!
Answer:
A = 254.5 mm^2
Step-by-step explanation:
The radius of this circle is 9 mm.
Using the formula A = (pi)r^2, we find the area of this particular circle to be:
A = (pi)(9 mm)^2, or
A = 254.5 mm^2

Find the sum of the first 47 terms of the following series, to the nearest integer.
12, 16. 20. ...
Answer:
The sum of the first 47 terms of the series, 12, 16, 20, ... S₄₈ is 4,888
Step-by-step explanation:
The given series is;
12, 16, 20, ...,
Therefore, the first term of the series is, a = 12
The common difference of series is found as follows;
The difference between subsequent terms, 12 and 16 is 16 - 12 = 4
The difference between subsequent terms, 16, and 20 is 20 - 16 = 4
Therefore, the common difference, d = 4
The series is therefore an arithmetic projection, AP
The sum of the first 'n' terms of an AP, Sₙ, is given as follows;
[tex]S_n = \dfrac{n}{2} \cdot \left [2 \cdot a + (n - 1)\cdot d \right ][/tex]
(47/2)*(2*12+(47-1)*4)
The sum of the first 47 terms is therefore given as follows;
[tex]S_n = \dfrac{47}{2} \cdot \left [2 \times 12 + (47 - 1)\times 4 \right ] = 4,888[/tex]
The sum of the first 47 terms of the series, 12, 16, 20, ... S₄₈ = 4,888

A triangular prism and its dimensions are shown in the diagram. What is the lateral surface area of this triangular prism in square centimeters? F 192 cm2 G 128 cm2 H 152 cm2 J 144 cm
Answer:
G
The lateral surface area of the triangular prism is 128 square centimeters. The correct answer would be an option (G) 128 cm².
What is the triangular prism?A triangular prism is a three-sided prism consisting of a triangular base, a translated duplicate, and three faces connecting similar sides.
As per the question, we have dimension are:
side legth of base = 6 cm, 5 cm, and 5 cm
height = 8 cm
Lateral surface area = (a+b+c)h
Substitute the values and we get
Lateral surface area = (6+5+5)8
Lateral surface area = 16 × 8
Lateral surface area = 128 cm².
Hence, the lateral surface area of the triangular prism is 128 square centimeters.

Find the indicated probability
The probability that Luis will pass his statistics test is 0.4. Find the probability that he will not pass his statistics test
O A. 20.00
OB. 2.50
O C. 0.6
OD. 66.67
Answer:
C. 0.6
Step-by-step explanation:
If the probability of him passing is 0.4 then thats a 40% chance. But they're asking the probability of him failing so 100%-40%= 60%
60% = 0.6 in this scenario.
There is a 0.6 chance he will fail.
