Answer:

80 gifts

Step-by-step explanation:

Maddison hid 12 of her sister's birthday gifts around the house. If this was 15% of the gifts, how many total gifts did her sister have?

Let the Total gifts that her sister has be represented by x

Hence:

15% of x = 12

15/100 × x = 12

15x /100 = 12

Cross Multiply

15x = 100 × 12

15x = 1200

x = 1200/15

x = 80 gifts

Hence, the total gifts her sister has is 80 gifts

Answer:

80 total gifts

Step-by-step explanation:

Step one:

given data

Maddison hid 12 of her sister's birthday gifts

we are told that 12 gift is 15% of the total gifts

let the total gifts be x

so

=15/100*x= 12

=0.15x= 12

divide both sides by 0.15

x= 12/0.15

x=80 total gifts

Branda and Laurie have rectangular shaped backyards. Branda's yard measures 35 feet by 90 feet. Laurie's yard measures 40 feet b
tia_tia [17]
To find the area of each backyard, we need to multiply the length and width together.

For Branda, her yard is 35 by 90, which means the area is 35*90 which = 3150.

For Laurie, her yard is 40 by 65, which means the area is 40*65 which = 2600.

Now, we are asked to find the difference between Branda and Lauries yard areas. The difference means how much larger Branda's area is than Lauries. 

This means we have to subtract Laurie's area from Branda's.

So, we do 3150 - 2600 = 550 

So, our answer is 550ft^2

Based on information from Consumer Reports, a random sample of 35 thirty-gram cookies had a sample mean of 146 calories. The sta
Nonamiya [84]

Using the z-distribution, it is found that the 90% confidence interval for mean calories in a 30-gram serving of all chocolate chip cookies is (143, 149).

We are given the <em>standard deviation</em> for the population, which is why the <em>z-distribution </em>is used to solve this question.

The information given is:

  • Sample mean of \overline{x} = 146.
  • Population standard deviation of \sigma = 12.
  • Sample size of n = 65.

The confidence interval is:

\overline{x} \pm z\frac{\sigma}{\sqrt{n}}

The critical value, using a z-distribution calculator, for a <u>95% confidence interval</u> is z = 1.645, hence:

\overline{x} - z\frac{\sigma}{\sqrt{n}} = 146 - 1.645\frac{12}{\sqrt{35}} = 143

\overline{x} + z\frac{\sigma}{\sqrt{n}} = 146 + 1.645\frac{12}{\sqrt{35}} = 149

The 90% confidence interval for mean calories in a 30-gram serving of all chocolate chip cookies is (143, 149).
