The total rainfall in Forks, Washington, this October was 8 3/8 in. In September, 60% less rain fell than in October.
lakkis [162]
Given:
October: 8 3/8 inches
September : 60% less rain fell than in October.

This means that only 40% rain fell in September based on the amount of rain that fell in October.

8 3/8 ⇒ (8*8)+3/8 = 67/8
40% is 4/10

67/8 * 4/10 = 268/80 = 3 28/80 or 3 7/20 or 3.35

28 ÷ 2 = 14
80 ÷ 2 = 40
14 ÷ 2 =   7
40 ÷ 2 = 20

In September 3 7/20 inches or 3.35 inches of rain fell.

A dietitian wants to know the average time spent on breakfast in a primary school. The dietitian randomly samples 25 students an
blsea [12.9K]

Answer:

The right options are:

a. The margin of error is 0.632

f. There is a 95% chance that the true mean is between 11.968 and 13.232 minutes.

<em />

Step-by-step explanation:

<em>The question is incomplete:</em>

<em>Select one or more:</em>

<em>a. The margin of error is 0.632</em>

<em>b. The margin of error is 1264.</em>

<em>C. The margin of error is 0.600.</em>

<em>d. We believe that the true mean time spent on breakfast is between 11.968 and 13.232 minutes.</em>

<em>e. If we take many other samples from this population, 95% of them will have a sample mean that is between 11968 and 13232.</em>

<em>f. There is a 95% chance that the true mean is between 11.968 and 13.232 minutes.</em>

The margin of error can be calculated from the bounds of the confidence interval as:

E=\dfrac{UL-LL}{2}=\dfrac{13.232-11.968}{2}=\dfrac{1.264}{2}=0.632

As the confidence interval is calculated at 95% confidence, we are 95% confident that the true mean is within the calculated interval. We are not 100% confident although (that's why Option d is false).

This interval does not give us information about the sampling distribution (option e is false).

5x + 19.95 = 35 <br> Solve x
solniwko [45]

Answer:

Answer is x=3+0.05/5

Step-by-step explanation:

5x+19.95=35

We move all terms to the left:

5x+19.95-(35)=0

We add all the numbers together, and all the variables

5x-15.05=0

We move all terms containing x to the left, all other terms to the right

5x=15.05

x=15.05/5

x=3+0.05/5

I hope it's helpful!!
