Since 1 hour is equal to 3/4 Batch of cupcakes, then you would have to divide
Answer:
5 11/12
Step-by-step explanation:
2 4/16 = 2 1/4
2 1/4 + 3 2/3 = 9/4 + 11/3
27/12 + 44/12 = 71/12 = 5 11/12
Answer:
No. When all you want to do is estimate a population parameter, you should construct a confidence interval.
Step-by-step explanation:
In this case, there is no other prior estimation about the population to test (a hypothesis to nullify). The only thing you can do is construct a confidence interval of the proportion, where the standard deviation can be calculated in function of the proportion and the sample size.
The right answer is E: "No. When all you want to do is estimate a population parameter, you should construct a confidence interval."
Step-by-step explanation:
The expressions are not properly written
Given
RS = 4x – 9
ST = 19
RT = 8x – 14
Based on the given parameters, the addition postulate below is true
RS+ST = RT
Substitute
4x-9+19 = 8x-14
collect like terms
4x-8x = -14-19+9
-4x = -33+9
-4x = -24
x = -24/-4
x = 6
Get RS:
RS = 4x-9
RS = 4(6)- 9
RS = 24-9
RS = 15
Get RT:
RT = 8x - 14
RT = 8(6)-14
RT = 48-14
RT = 34
Note that they together ate all of the pizza.
Therefore the total fractions they ate should add up to 1.
By letting the fraction Jodie ate be x.
x + 2/5 + 1/4 = 1
x = 7/20
The answer is 7/20.
