Answer:

[tex]\sf\frac{-4+6}{2}[/tex] = 1

Step-by-step explanation:

Let's solve the problem,

→ (-4 + 6)/2

→ 2/2 = 1

Hence, the solution is 1.

The null hypothesis is [tex]H_0:\mu=3[/tex] and the alternative hypothesis is [tex]H_1:\mu > 3[/tex]

There are two hypothesis considered in a statistical test. They are:

Formulation of null and alternative hypothesis are considered as the first step of a statistical procedure. The whole procedure, then, continues on testing whether to accept or reject these hypotheses.

Null Hypothesis is the actual hypothesis which is tested. Alternative hypothesis, as its name suggests, is the hypothesis accepted when the null hypothesis is rejected in the test carried out.

Here the sociologist is carrying out the test on the mean number of cars, [tex]\mu[/tex].

So to check whether the families own more than 3 cars in average,

the null hypothesis will be ,[tex]\bold{H_0:\mu=3}[/tex]  

and the alternate hypothesis will be,  [tex]\bold{H_1:\mu > 3}[/tex]

So if the null hypothesis is rejected, then there is the possibility for only more than 3 cars in average.

Answer:

66.8 inches

Step-by-step explanation:

The mean height of 16 students is 67.0"

Total height of 16 students = 67 x 16 = 1,072"

When Danielle walks into the class an additional height of 63.6" is added to the total and the new total becomes 1072 + 63.6 = 1135.6"

Since there are now 17 students, mean = 1135.6/17 = 66.8"

The Perimeter of the polygon = 22.43 units.

Given the vertices of the polygon as:

The perimeter of the polygon is the sum of all its sides, UV + VW + UW.

Apply the distance formula, d = [tex]\sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex] to find the length of each of the three sides of the polygon as shown below:

UV = √[(3−(−2))² + (4−4)²]

UV = √[(5)² + (0)²]

UV = √25

UV = 5 units

VW = √[(3−3)² + (4−(−4))²]

VW = √64 = 8 units

UW = √[(−2−3)² + (4−(−4))²]

UW = √89 = 9.43 units

Answer:

Step-by-step explanation:

The slope of the line = rise/run = 2/3.

To determine the slope of a line, we can find the ratio of the rise of the line to that of its run.

Therefore, slope (m) of a line = rise/run.

Rise = vertical distance across the line

Run = horizontal distance across the line

In the graph given, we have:

Rise is the blue line = 6 units

Run is the red line = 9 units

Slope of the line (m) = 6 units/9 units

Slope of the line (m) = 2/3

Therefore, In simplest form, the slope of the line = rise/run = 2/3.

Answer:

x = 5

Step-by-step explanation:

Because an isosceles triangle's angles will always add up to 180, it's quite simple plugging in angle J into a formula to find our answer.

Before we begin, recall that the bottom two angles of an isosceles triangle are equal to the other. Thus:

Unknown angle (H) = 14x+1

So...

38 + 14x + 1 + 14 x + 1 = 180

40 + 28x = 180
-40             -40
28x = 180

28x/28 = 180/28

We get:
x = 5

Answer:

[tex]x = 5[/tex]

Step-by-step explanation:

Note that:

Calculating For the Value Of X

(14x + 1)° + (14x +1)° +38° = 180°

14x + 1 + 14x + 1 + 38 = 180°

28x + 2 + 38 = 180°

28x + 40 = 180°

28x = 180 - 40

28x = 140

x =5

Therefore the value of x is 5

If the grid and tanya start typing at the same time, tanya have typed 14.67 pages.

A ratio indicates how many times one number contains another. If a and b are to objects then ratio of a to the b is given as a : b.

Now it is given that,

Pages typed by Ingrid = 3

Pages typed by Tanya = 4

So, the ratio of pages, Ingrid : Tanya = 3 : 4

So,  If the grid and tanya start typing at the same time Ingrid has typed 11 pages

Thus, dividing the ratio be 3 we get,

3 : 4 = 1 : 1.33

Now for 11 pages multiplying 1.33 with 11 we get,

1.33 x 11 = 14.67

Step-by-step explanation:

To tell if something is longer than another object is to find the difference between the two objects.

If the difference is < 0, then the object is shorter

If the difference is = 0, then the objects are equal in length

If the difference is > 0, then the object is longer

[tex]6.5 * 10^{-9}[/tex] - [tex]4.75 * 10^{-9}[/tex] = [tex]1.75*10^{-9}[/tex]

[tex]f(3)=(3)^2-5(3)+14\\f(3)=8\\\\f(5)=(5)^2-5(5)+14\\f(5)=14[/tex]

We conclude that the frist trip takes 2.75 hours and the second one 2.5 hours.

Remember the relation:

Distance = Speed*Time.

Here the total distance of the trip is 55mi + 50mi = 105mi

And the total time is 5 hours and 15 minutes, remember that:

60 min = 1 hour

Then; 15 min = 0.25 hours.

So the total time is 5.25 hours, with that we conclude that the average speed is:

S = 105mi/5.25 h = 20 mi/h

The first trip is 55 miles long, then the time in which it is travelled is:

T = (55 mi)/(20 mi/h) = 2.75 hours

The second trip is 50 miles long, then:

T' = (50mi)/(20 mi/h) = 2.5 hours.

We conclude that the frist trip takes 2.75 hours and the second one 2.5 hours.

For you and your sister to reach bottom at the same time, the large Ferris wheel has to take 7 revolutions and the small Ferris wheel has to take 10 revolutions.

Time taken by the large Ferris wheel to complete 1 revolution = 10 seconds.

Time taken by the small Ferris wheel to complete 1 revolution = 7 seconds.
