Answer:
f-1 (1/2) =2, f-1(8) = 6
Step-by-step explanation:
i did it on edge
The total amount of people who ordered a large is 5 + 12 + 8 = 25 people.
The amount of customers who bought a large cold drink is 5.
The probability that someone bought a large cold drink is 5 out of 25 people.
This is 5/25 which is 1/5 which is .2
Convert the decimal to a fraction by multiplying by 100 and adding a percent sign at the end.
.2 x 100 = 20%
Edit:
The probability was supposed to be if the customer ordered a cold drink based on people who ordered large.
The amount of people who ordered a large drink is 22 + 5 = 27.
The amount of people who ordered a cold large is 5.
To find the percent, divide the people who ordered cold large by the total people who ordered large.
This would be 5/27 which in decimal form is .185185
To convert to a percent, multiply by 100 and add a percent sign after it.
.185185 x 100 = 18.5185%
The question says to round to the nearest percent so your answer is:
19%
Answer:
10/3
Step-by-step explanation:
-1(6h + 7) = -6h - 7
-6h - 7 + 8 = -6h + 1
-6h + 1 = -19
-1 -1 <em>- Subtract 1 from both sides.</em>
-6h = -20
-6 -6<em> - Divide both sides by negative 6</em>
h = 10/3

Answer:
Internal validity
Step-by-step explanation:
The internal validity here is weak
Internal validity describes the extent to which an evidence weighs the cause and effect claim. In this study, the internal validity that brought about failure in the new exam is mainly due to the environment where the exam was written and not the new exam itself.
So this validity is weak in claiming that the new exam is not a good substitute for the old exam.
Putting them in the same good environment might help the researchers to draw a better conclusion.
