Answer:

Total tickets = 70

Total cost = $550

Adult's ticket = $9

Child's ticket = $5

Difference = 9 - 5 = $4

Assume all 70 are child's tickets

5 x 70 = 350

But the total cost was 550

550 - 350 = $200

The $200 must have come from Adult's tickets, which has a difference of $4.

200 ÷ 4 = 50

So there are 50 adult's tickets.

70 - 50 = 20

And there are 20 child's tickets.

Step-by-step explanation:

Using the t-distribution, as we have the standard deviation for the sample, we have that the test statistic is given by:

[tex]t = \frac{-20 - 0}{\sqrt{\frac{32.66}{7}}}[/tex]

At the null hypothesis, it is tested if there is no difference, that is:

[tex]H_0: \mu = 0[/tex]

At the alternative hypothesis, it is tested if there is a difference, that is:

[tex]H_1: \mu \neq 0[/tex]

The test statistic is given by:

[tex]t = \frac{\overline{x} - \mu}{\frac{s}{\sqrt{n}}}[/tex]

The parameters are:

In this problem, [tex]\mu = 0[/tex] is tested at the null hypothesis, and the sample is: 20, -40, -40, 0, 20, - 60, -40, hence:

[tex]\overline{x} = -20, s = \sqrt{32.66}, n = 7[/tex].

Hence, the test statistic is:

[tex]t = \frac{\overline{x} - \mu}{\frac{s}{\sqrt{n}}}[/tex]

[tex]t = \frac{-20 - 0}{\frac{\sqrt{32.66}}{\sqrt{7}}}[/tex]

[tex]t = \frac{-20 - 0}{\sqrt{\frac{32.66}{7}}}[/tex]

The number of bread loves to sell to break even is 19, thus, Joan is practical in this situation, so option D is correct.

A graph is a structure made up of a collection of things, where some object pairs are conceptually "connected." The items are represented by mathematical abstractions known as vertices, and each pair of connected vertices is referred to as an edge.

Given:

Joan determines that she will need to sell 19 loaves of bread in order to break even,

As you see from the graph,

The coordinate of the cost line can be determined by (0, 80) and (11, 110) and the coordinates of the income line can be determined as (0, 0) and (10, 70)

Write the equation of the line as shown below,

y - 80 = 110 - 80 / 11 - 0 (x - 0)

y - 80 = 30 / 11 x

And y = 70 / 10 x

Solve the above equation, you will get the value of x and y,

x = 18.72 and y = 7 × 18.72 = 131.06

Joan can break even when she sold  18.72 of bread, but the bread loaves can't be divided into further pieces, thus she has to sell 19 to break even.

The distance in miles the boat traveled for the modeled function of speed and time is,

[tex](f .g)(2) = 44[/tex]

The rate of speed is the rate at which the total distance is travelled in the time taken.

The function which represents the rate of a boat traveling with the current in miles per hour is,

[tex]f(x) = 2x^2+ 3[/tex]

The function which represents the time the boat traveled in hours is,

[tex]g(x) = x+ 2[/tex]

The distance traveled by boat is the product of rate of speed of the boat and time taken by the boat. Thus, the multiplication function for the above two function can be given as,

[tex](f.g)(x)=(2x^2+3)(x+2)[/tex]

Solve the above function for (f • g)(2) as,

[tex](f.g)(2)=(2(2)^2+3)(2+2)\\(f.g)(2)=(8+3)(4)\\(f.g)(2)=44[/tex]

Interpret the above answer with the given option we get,  (f • g)(2) = 44, the distance in miles the boat traveled

Hence, the distance in miles the boat traveled for the modeled function of speed and time is,

[tex](f .g)(2) = 44[/tex]

Answer:

T(n) = 9n - 24

Step-by-step explanation:

The first term is -15, therefore a = -15

The difference between the 1st and 2nd term is 9, therefore d = 9.

Set up the equation with T(n) = a + (n-1)d

T(n) = -15 + (n-1)(9) = 9n - 24

The mean amount of precipitation from 2005 to 2013 is 5.33 inches.

It is given that

precipitation in 2005 = 5.98 inch

precipitation in 2006 = 6.05 inch

precipitation in 2007 = 7.59 inch

precipitation in 2008 = 5.27 inch

precipitation in 2009 = 3.11 inch

precipitation in 2010 = 7.18 inch

precipitation in 2011 = 2.95 inch

precipitation in 2012 = 7.22 inch

precipitation in 2013 = 2.61 inch

The mean value is the ratio of the sum of all observations to the number of observations.

Sum of observation = 47.96

Number of observations = 9

Mean = 47.96/9 = 5.33 inches

Therefore mean amount of precipitation from 2005 to 2013 is 5.33 inches.
