Answer: for number 1 is 72

Step-by-step explanation:

1. The rectangle‘s formula is b x w so it would be 8x6 which equals 48.

2. The formula for each Triangle is b x h and you would divide it by two (3 x 8 divided by 2 = 12) but you have 2 triangles that were put together to make it seem like 1 triangle if you can see it. 12 x 2 is 24

The selected statistical questions are as follows:

<em>A what is the typical amount of rainfall for the month of June in the Galapagos islands</em>

<em />

<em>D how many songs does the class usually listen to each day</em>

<em />

<em>G how long does it typically take for 2nd graders to walk a lap around the track</em>

Statistical questions are known by these two main characteristics:

  • they are answered by the collection of data
  • there is always variability in the data collected

This means that the data vary.  They are not the same data.  For example, "How old is Monday?" is not a statistical question because it has one answer.

Thus, statistical questions are not answered by a single number or answer, especially when the correct answer is just one.

A train is traveling at a constant speed and goes 17 kilometers in 8 minutes. How far will the train travel in 60 minutes.
allsm [11]

Answer:

Distance B = 1275 kilometers.

Step-by-step explanation:

Let the two distances and time be A and B respectively.

Given the following data;

Distance A = 17 kilometers.

Time A = 8 minutes.

Distance B =?

Time B = 60 minutes.

First of all, we would find the constant speed;

Speed = distance/time

Substituting into the equation, we have;

Speed = 17/8

Speed = 2.125 km/m

Now, to find the distance B;

Distance B = speed * time

Distance B = 2.125 * 60

<em>Distance B = 1275 km</em>

Carter Motor Company claims that its new sedan, the Libra, will average better than 26 miles per gallon in the city. Use μ, the
Aleonysh [2.5K]

Answer:

The true average mileage of the Libra  Using Null hypothesis is as ;

H0:μ≤26

(Ha):μ >26

Step-by-step explanation:

Given:

Libra, will average better than 26 miles per gallon in the city

To Find:

Average mileage of the Libra.

Solution:

This problem is related to the null hypothesis  and alternate hypothesis.

i.e Null Hypothesis is the statement which is true and statement which contradictory is called alternate hypothesis.

<em>“reject H0” if the sample information favors the alternative hypothesis. </em>

<em>“do not reject H0” / “decline to reject H0” if the sample information is insufficient to reject the null hypothesis</em>

So given that condition is libra will have average better than 26

So it will include 26 and above values .

i.e. True  condition is called as null hypothesis (H0)

so true average will be greater than 26

So H0:μ≤26

And the Alternate hypothesis will be the contradictory to true condition

(Ha):μ >26 .
