The marks that have to be scored in 6th test to make the average 85 is 105 .
Average of a data set is the ratio of sum of all the data to the number of data in the set.
It is given that the average score = 81
Total tests up till now = 5
Total tests overall = 6
New Average = 85
Let the sum of the score for 5 tests is x
Then by the formula of average
x / 5 = 81
x = 405
Now let the marks scored in the 6th test is y
then ( 405 +y) / 6 = 85
405 + y = 510
y = 105
Therefore , the marks that have to be scored in 6th test to make the average 85 is 105 .

false... even if you got 100 on the next test, you would only have an 84 average
Hope this helped!!! :) (comment if you don't understand)
Answer:
Banana recipe will require 12 table spoons of butter.
Step-by-step explanation:
Banana bread recipe requires the butter = cups
Since cup = 1 table spoon
Therefore, 1 cup = = 16 table spoons
Therefore, cup of butter =
= 12 table spoons of butter
So Banana recipe will require 12 table spoons of butter.
A sailfish can swim a distance of 204 miles in 3 hours if it maintains its top speed of 68 miles per hour throughout.
In order to determine how far a sailfish can swim in 3 hours, we can use the speed given which is 68 miles per hour. This speed implies that the sailfish can swim 68 miles every one hour.
Therefore, it's reasonable to estimate that a sailfish can cover 204 miles in a span of 3 hours, assuming it maintains its top speed the entire time.

of the popular vote and candidate B would receive 46
%
of the popular vote. The margin of error was reported to be 5
%.
The group reported that the race was too close to call. Use the concept of a confidence interval to explain what this means.
Answer:
Step-by-step explanation:
number of likely voters = 2022
candidate A = 49%
candidate B = 46%
margin of error = 5%
using the concept of a confidence interval to explain
from the result of the poll conducted candidate A scored 49% of the votes while Candidate B scored 46% therefore the difference between the two voters is 3%.
also the margin of error is 5% which is higher than the 3% difference between the candidates. this margin error means that the 5% can vote for either candidate A or candidate B .which makes the results TOO CLOSE TO CALL

The ratio surface area of toy A : surface area of toy B is 7:9
The volume of toy B is 20 cm

Work out the volume of toy A.
Give your answer correct to 3 significant figures.
The volume of toy A will be equal to 13.7 cubic centimetres.
An ordered pair of numbers a and b, represented as a / b, is a ratio if b is not equal to 0. A proportion is an equation that sets two ratios at the same value.
The numerical relationship between two values demonstrates how frequently one value contains or is contained within another.
Given that the ratio surface area of toy A: to the surface area of toy B is 7:9. The volume of toy B is 20 cm
The computation of the volume of toy A is shown below:
7 × k²=9
k²= 9 ÷ 7
k=√(9 ÷ 7)
k = 1.133893419
Now
The volume of toy A = 20 ÷ 1.133893419³
The volume of toy A = 13.7 cubic centimetres
Therefore, the volume of toy A will be equal to 13.7 cubic centimetres.
The missing figure is attached with the answer below.

Answer:
13.7
Step-by-step explanation:
7*k²=9
k²=9/7
k=√9/7
k=1.133893419
20/1.133893419³=13.7
A.
10
B.
12
C.
24
D.
40
the answer is B.12 because 8*2=16 and 28-16=12
