The total number of adult tickets sold for the school play is 205 tickets if the total of 337 tickets were sold for the school play.

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

Let's suppose the number of adult tickets is x

So the number of student tickets is (x-73)

x + (x-73) = 337

2x—73 = 337

2x = 410

x = 205 tickets

Thus, the total number of adult tickets sold for the school play is 205 tickets if the total of 337 tickets were sold for the school play.

Using the t-distribution, it is found that the 90% confidence interval is (48.3, 48.7), hence 48.8 is not within the interval.

The confidence interval is:

[tex]\overline{x} \pm t\frac{s}{\sqrt{n}}[/tex]

In which:

The critical value, using a t-distribution calculator, for a two-tailed 90% confidence interval, with 225 - 1 = 224 df, is t = 1.6517.

The other parameters are given as follows:

[tex]\overline{x} = 48.5, s = 1.8, n = 225[/tex].

Hence the bounds of the interval are given by:

[tex]\overline{x} - t\frac{s}{\sqrt{n}} = 48.5 - 1.6517\frac{1.8}{\sqrt{225}} = 48.3[/tex]

[tex]\overline{x} + t\frac{s}{\sqrt{n}} = 48.5 + 1.6517\frac{1.8}{\sqrt{225}} = 48.7[/tex]

The 90% confidence interval is (48.3, 48.7), hence 48.8 is not within the interval.

4: likely

Step-by-step explanation:

Question 3:

the spinner has 1, 2, 3, 4, 5, 6

2, 4, 6 are all even number which is 3 / 6 = 1 / 2

so half a chance can be odd or half even possibility of landing

Question 4:

- 13 yellow

- 4 green

- 3 blue

total marbles: 13 + 4 + 3 = 20

yellow / total = 13 / 20

which is more than half of the marbles are yellow

If the volume of the popcorn box is 74 cubic inches. Then the length of the popcorn box in inches will be 0.3 inches.

A rectangular prism is a closed solid that has two parallel rectangular bases connected by a rectangle surface.

Gabriel models the volume of a popcorn box as a right rectangular prism and the box can hold 74 cubic inches of popcorn when it is full.

Its width is 3 and 1/2 in and its height is 77 in.

Then the width of the prism will be

[tex]\rm W = 3 + \dfrac{1}{2}\\\\W = \dfrac{7}{2}[/tex]

Then the length of the popcorn box in inches will be

[tex]\rm V \ = LWH\\\\\\74= L \times \dfrac{7}{2} \times 77\\\\\\L\ = 0.2745 \approx 0.3[/tex]

Answer: the real answer is 3 inches not 0.3.

Step-by-step explanation:

Formula: V=lwh

You are searching for its length, so if width is 3 1/2 then it will convert to 3.5

V=lwh

75=L(3.5)(7)

The value of minor arc, major arc and central angles given below:

An arc measure is an angle the arc makes at the center of a circle, whereas the arc length is the span along the arc.

Given: BOF= 126

angle BOF= angle COE= 126 (Vertically opposite angle)

Now,  

angle BOF + angle BOC= 180   (Linear pair)

     BOC=180-126= 54

and, COE= COD+ DOE

              = COD+COD

        126       =2COD

      COD= 63

now, BOD= BOC++COD

                 = 54+63

                = 117

Arc length of BCD= 87/360*2πr

= 2.041r

2. minor arc:

arc BF= 126/360* 2πr

           = 2.198r

arc FE= 54/360*2πr

          = 0.942r

arc DE= 63/360*2πr

          = 1.099r

arc CD= 63/360*2πr= 1.099r

arc CDE=126/360*2πr

             = 2.198 r

3. major arc

 arc BFED= 243/360*2πr

                 = 4.239r

arc FBCD=  243/360*2πr

                 = 4.239r

arc DCBFE= 297/360*2πr

                  = 5.181r

arc CBFE= 234/360*2πr

Based on the game involving rolling a number cube, the applicable statements are:

There are six sides of a number cube which means that the sample space is all the sides the cube can land on which are 1,2,3,4,5, and 6.

Because there are 3 odd numbers which can give you a negative point, and 3 even numbers which can give a point, the expected value is 0 as these cancel each other out.

This makes the game fair because situations that have an expected value of 0 are considered fair because there are no expected losses or profits.
