Sample 1 12 13 11 8 9 7 4
8 9 10 Mean = 9.1
Sample 2 7 12 11 8 9 8 12 8 9 10 Mean = 9.4
Sample 3 11 9 8 12 8 10 7 8 7 9 Mean = 8.9
Which statement is most accurate based on the data?
A. A prediction based on the data is reliable, because the means of
the samples are close together.
OB. A prediction based on the data is reliable, because each sample
has 10 data points.
O C. A prediction based on the data is not completely reliable, because
the means are not the same.
D. A ediction based on the data is not completely reliable, because
the means of samples 1 and 2 are greater than 9 and the mean of
sample 3 is less than 9.

Answer:
A prediction based on the data is reliable, because the means of the samples are close together.
Step-by-step explanation:
Test approved
The most accurate statement is A. A prediction based on the data is reliable, because the means of the samples are close together.
What is Mean?Mean of a set of data is defined as the average of all the values. It gives the exact middle point of the data set.
Given three data sets.
All the samples have 10 data points.
Number of data points = 10
Mean of sample 1 = 9.1
Mean of sample 2 = 9.4
Mean of sample 3 = 8.9
We can see that the mean of the three samples is so close to each other.
So the data is reliable.
Hence the option is A.

Answer:
[tex]After\ Tax = 7490[/tex]
Step-by-step explanation:
Given
[tex]Days = 2[/tex]
[tex]Rent = 3500[/tex] daily
[tex]Tax = 7\%[/tex]
Required
The total amount paid
For a day, he pays (without tax)
[tex]Rent = 3500[/tex]
For 2 days, he pays
[tex]Rent = 3500 * 2[/tex]
[tex]Rent = 7000[/tex]
After tax, his bills is:
[tex]After\ Tax = Rent + Rent * Tax[/tex]
[tex]After\ Tax = 7000 + 7000* 7\%[/tex]
[tex]After\ Tax = 7000 + 490[/tex]
[tex]After\ Tax = 7490[/tex]
2. Adam borrows $6,000 from his parents today for university fees and he promises
to pay a lump sum of $6,900 in 3 years' time. Calculate the following quantities
for the repayment arrangement:
(a) the effective annual interest rate.
(b) the equivalent simple annual interest rate.
Answer:
A) 4.77%.
B) 5%.
Step-by-step explanation:
Given that Adam borrows $ 6,000 from his parents today for university fees and he promises to pay a lump sum of $ 6,900 in 3 years' time, to calculate the effective annual interest rate and the equivalent simple annual interest rate the following calculations must be performed:
A)
6,900 = 6,000 x (1 + X / 1) ^ 3x1
6,900 = 6,000 x 1X ^ 3
6,900 = 6,000 x 1 x 4.77 ^ 3
Thus, the interest rate of said investment is 4.77% per year.
B)
(6,900 - 6,000) / 3 = 300
6,000 = 100
300 = X
300 x 100 / 6,000 = X
30000 / 6,000 = X
5 = X
Thus, the simple interest rate would be 5% per year.

how many shapes of size A are in B ?
I counted 9.5
then just multiply the count * the size of A
got it?
Step-by-step explanation:
area of shape A = 3cm²
number of A shape in shape B = 9 and half
1 shape A = 3cm²
9 shape A = 3×9 = 27cm²
1 half shape A = 3 ÷ 2 = 1.5cm²
area of shape B = 27cm² + 1.5cm² = 28.5cm²

big circle of radius
35cm
Answer:
Let get x as a number of small circles.
Area of big circle = Area of all small circles
(Here . implies multiplication)
22/7 . 35 cm .35cm = 22/7 . 7cm .7cm .x
x = (22/7 . 35 cm .35cm) / (22/7 . 7 cm .7cm)
x = (35 . 35) /(7.7)
x = 25

Mary always saved 45% of his salary. When his salary decreased by 20% in April, his savings decreased by $180.
How much was Mary’s salary before the decease?
Answer:
Step-by-step explanation:
Answer:
Is Mary a guy? :|
Step-by-step explanation:
I did this by just a good guess , not really the right way
2000*.45=900 ( 900 is the old savings)
2000*.2 =400 ( how much her salary went down by )
2000-400=1600 ( new salary )
1600*.45 = 720 ( 45% of new salary is new savings
900-720=180 ( change in savings is 180 , the amount the question asks for)
Mary's old salary was 2,000
