Answer:

3) b= 11 3/5

4) n= 1/18

5) 5/12 feet

Step-by-step explanation:

3) add -3 2/5 to both sides

4) multiply both sides by 3n, divide by -42, then divide 7/42 by 3 (or multiply it by the reciprocal: 1/3)

5) convert the height to inches by multiplying by 12, subtract 69 from 74, then divide answer by 12

Omar has 2 3/4 cups of dough to make dumplings. If he use 3/16 cup of dough for each dumpling, how many whole dumplings can Omar
andrey2020 [161]

Answer:

14

Step-by-step explanation:

Omar can make 14 whole dumplings. You change 2 3/4 cups to an improper fraction ( multiply the denominator and add the numerator ) and you get 11/4. Since you need 3/16 cups for one dumpling you have to find the greatest common denominator which is 16. You multiply 4 by 11 to get the numerator and end up with 44/16. Since you need 3/16 for one whole dumping you divide 44 by 3 and get 14.6 repeating. You cannot have a fraction of a dumpling so you round down and get the answer 14.

If the critical z-value for a hypothesis test... If the critical z-value for a hypothesis test equals 2.45, what value of the te
schepotkina [342]

Answer: z score = 0.00714

Step-by-step explanation: the value of test statistics is gotten using the standard normal distribution table.

Z= 2.45 has area to the left (z<2.45) and area to the right (z>2.45).

Level of significance α is the probability of committing a type 1 error. The area under the distribution is known as the rejection region and it is the area towards the right of the distribution.

The table I'm using is towards the left of the distribution.

But z>2.45 + z<2.45 = 1

z> 2.45 = 1 - z<2.45

But z < 2.45 = 0.99286

z > 2.45 = 1 - 0.99286

z >2.45 = 0.00714

Hence the test statistics that would produce the least type 1 error is 0.00714
