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
The zeros are x=-2.25 and x=0.25
ANSWER
EXPLANATION
The given triangle is a right triangle.
It was given that,
and
Using the Pythagoras Theorem, we can determine the value of c.
The ratio is the adjacent over the hypotenuse.
We rationalize to get:
Answer:
19 < x < 31
Step-by-step explanation:
The range for the third side is
25-6 < x < 25+6
19 < x < 31
Take the other two sides and subtract and take the other two sides and add
Answer:
75 cheeseburgers and 86 french fries
Step-by-step explanation:
This is a guessing math problem so do a random amount and change amount of items to get closer to the answer
81 x 3 = $243
80 x 1.50 = $120
243 + 120 = 363 -354 = 9 dollars
we need nine less dollars so 9/1.5 = 6 so six more fries
86 x 1.5 = 129
75 x 3 = 225
129 + 225 = $354
