Answer:
718
Step-by-step explanation:
It can be done this way:
4% of 50.0 is 2.0
4% of 900 is 36
4% of 7000 is 280
4% of 10,000 is 400
add them all up and we have:
400 + 280 + 36 + 2 = 600 + 110 + 8 = 718
Answer: C) H0 : μ = 250 , Ha: μ < 250
Step-by-step explanation:
The questions is incomplete. The correct question is
A restaurant advertises that its burritos weigh 250 g. A consumer advocacy group doubts this claim, and they obtain a random sample of these burritos to test if the mean weight is significantly lower than 250 g. Let u be the mean weight of the burritos at this restaurant and ĉ be the mean weight of the burritos in the sample. Which of the following is an appropriate set of hypotheses for their significance test? Choose 1 answer:
A) H0 : x = 250 , Ha : x < 250
B) H0 : x = 250 , Ha : x > 250
C) H0 : μ = 250 , Ha: μ < 250
C) H0 : μ = 250 , Ha: μ > 250
Solution:
The null hypothesis is the hypothesis that is assumed to be true. The restaurant advertises that its burritos weigh 250. This is the null hypothesis. 250 is the population mean,μ . Thus, the null hypothesis is
H0 : μ = 250
The alternative hypothesis is what the researcher expects or predicts. The consumer advocacy group tests if the mean weight is significantly lower than 250g. This is the alternative hypothesis. It is expressed as
H0 : μ < 250
Answer:
32 degree
Step-by-step explanation:
total pentagon exterior angles = 360 degrees
2x + 3x + 71 + 85 + 44 = 360
5x + 200 = 360
5x = 160
x = 32 degree
Mia gives $80 as tip to the movers.
<em><u>Explanation</u></em>
The moving company charged $500 for its service.
Suppose, the amount of tip is 
dollar, which is 16% of the total charge.
So, the equation will be.....
So, the amount of tip Mia gives the movers is $80
Given:
Rolling a fair dice.
To find:
The theoretical probability of rolling a number less than 5.
Solution:
The possible numbers of rolling a dice are 1, 2, 3, 4, 5, 6.
Total outcomes = 6
Numbers less than 5 are 1, 2, 3, 4.
Favorable outcomes = 4
Now, the theoretical probability of rolling a number less than 5 is:
In decimal form, it can be written as:
In percentage form, it can be written as:
Therefore, the theoretical probability of rolling a number less than 5 in the fraction, decimal and percent are 
and 
respectively.
