Nuetrik [128]

Answer:

The company's chocolate bars weigh 1.6 ounces on average.

Step-by-step explanation:

We are given that  a company claims that its chocolate bars weigh 1.6 ounces on average.

It took many large samples, and each time the mean weight of the sample was within the 95% confidence interval.

95% confidence level means a range of values that you can be 95% certain contains the true mean of the population.

A teacher needs 70 lengths of string cut to 40cm each. If balls of string are 10 m long, how many balls will be needed.
Genrish500 [490]

Answer:

3

Step-by-step explanation:

A ball is 10 meters. Since 100 centimeters are in a meter, each ball has 100*10 = 1000 centimeters.

The teacher needs 70 strings each 40 centimeters. The total amount they need is 70*40 = 2800 centimeters.

Since a ball has 1000 centimeters, 2800 centimeters will need 3 balls for a total of 3000 centimeters.

the sum of two numbers is 31. 2/3 of one of the numbers added is equal to 5/8 of the other.find the two numbers
Jet001 [13]
One number is 15 and the other is 16. You get this answer by first finding a factor of 3(15) that when it's subtracted from 31 gives you a factor of 8(16). Then you divide in this case 15 by 3 and get 5 and 16 by 8 and get 2. The reason you divided the numbers is because now you have 5 which is 1/3 of 15 and 2 which is 1/8 of 16. Now that you have your numbers that equal your fractions multiply 5 which is your 1/3 by the 2 from your 2/3 to get 10 which is 2/3 of 15 and 2 which is 1/8 by the 5 from you 5/8 to get 10 which is 5/8 of 16
