Answer:

Step-by-step explanation:

let 4th number = X

mean = 7

observations = 5, 7, 7, X

..............................................

mean = sum of observations ÷ numbers of observations

7 = 5+7+7+X ÷ 4

28 = 19 + X

28 - 19 = X

9 = X

The mean of the four numbers is 7. Three of the numbers are 5, 7, and 7. So, the 4th number would be 9.

The mean value of the data set is the ratio of the sum of the data set's values to the number of values it has.

If the data set consists of values

[tex]x_1, x_2, ..., x_n[/tex]

, then we get the mean value as:

[tex]\overline{x} = \dfrac{x_1 + x_2 + \cdots + x_n}{n}[/tex]

The mean of the four numbers is 7. Three of the numbers are 5, 7, and 7.

let 4th number = X

Mean = 7

observations = 5, 7, 7, X

Mean = sum of observations / numbers of observations

[tex]7 = 5+7+7+X / 4\\28 = 19 + X\\28 - 19 = X\\9 = X[/tex]

Step-by-step explanation:

Answer:

53.12ft

Step-by-step explanation:

Area of triangle:

The formula to find the area of a triangle is 1/2bh

- We plug in the values given.

1/2 x 8 x 7

Which is 28ft.

Area of semicircle:

The formula to find the area of a semicircle is 1/2[tex]\pi[/tex][tex]r^{2}[/tex]

- We plug in the values given

1/2 x [tex]\pi[/tex] x [tex]4^{2}[/tex]

1/2 x 16[tex]\pi[/tex]

8[tex]\pi[/tex] or 8 x 3.14 = 25.12

                    In order to get the total area of the whole shape we need to add the areas of those two, which will be 25.12 + 28 = 53.12

Answer: D. -9

Step-by-step explanation:

The median is the middle point in a dataset half of the data points are smaller than the median and half of the data points are larger. To find the median Arrange the data points from smallest to largest. If the number of data points is odd the median is the middle data point in the list.

Answer: 50 cases per minute

Step-by-step explanation:

1. Select one of the points on the graph. Let's use (2, 100) in this case.

2. Divide the number of cases (y) by the amount of minutes (x) This means the equation would be 100 ÷ 2.

3. Since 100 cases ÷ 2 minutes = 50 cases per minute, that means that is unit rate, which can be expressed by y = 50x or f(x) = 50x.

Answer:

I think T is the independant and B is the dependant

Step-by-step explanation:

the amount of time they have is not changed, however the amount of bands they can fit into that time slot is undetermined and relies on the time they have

Answer:

the first option

Step-by-step explanation:

independent is something you can change OR determine

dependent is something that will happen BECAUSE of the independent and you can not change it

in this case- the sentence states that " the amount of time that the venue has been reserved for DETERMINES how many bands will play"

You can change or schedule how long you want to reserve the venue but how many bands that will play depends on the independent variable (t)

Thats why it say determines, because (t) determines or changes (b)

Answer:

okay I'm not 100% sure but I have a good idea (it's okay if u remove me it's just an educated guess)

89%

Step-by-step explanation:

if there were 100 students that would mean 1 student represented 1% of the results. so if there were 50 students 1 student would represent 2% of the results. so if two students were removed then that would mean the result would improve by a total of 4% which would get you 89%
