08.01 MC)Below are the data collected from two random samples of 500 American students on the number of hours they spend in school per day (rounded to the nearest hour):


Number of hours in school per day 4 5 6 7 8
Sample A: Number of students 70 100 125 135 70
Sample B: Number of students 80 90 120 125 85


Meg concludes that students spend a mean of 7 hours in school each day. Tara thinks the mean is 6 hours. Who is correct—Meg or Tara? Explain your answer in two or three sentences. Make sure to use facts to support your answer.

Number of years between 1960 to 2010 = 2010-1960=50

So, average change will be = Difference in salaries of both years divided by difference in number of years(50)Answer:

Step-by-step explanation:

Answer:

it is c>7

Step-by-step explanation: hopefully that is the correct answer.

Answer:

B

Step-by-step explanation:

To solve this problem, first create an equation that you can use to find the answer. It would look like this:

510 = 60x + 150

Then, subtract 150 from each side to isolate x.

360 = 60x

Now, divide both sides by 60 to get the number of cars he needs to sell.

6 = x

Since he needs to make MORE than 510 dollars, he has to sell at least 7 or more cars, thus making B the correct answer. Hope this helps and please add a "Thanks!" if it did! :)

Answer:

74%

Step-by-step explanation:

looking left to right the each verticle "line "marks 25%

Notice how the entire line segment is split into 4 sections.

Section 1: 50 - 100

Section 2: 100 - 140

Section 3: 140 - 170

Section 4: 170 - 190

Since it's 4 sections, each section equals 25%

Here we need to find the percentage from 100 - 170

That means sections 2 - 3

Section 2 + Section 3 = 25% + 25% = 50%

Answer:

Answer:

0.54723 divided by 2 = 0.273615

Step-by-step explanation:

0.54723/2 = 0.273615

There is not much to show regarding steps, but this might help:

Dividing something by 2 means spliting the original value in half. This means that the product of the number of the original value that was divided by two is half of the orginial value. This means that 0.273615 + 0.273615 = 0.54723(the original value) because two halves make a whole.

0.54723 divided by 2 = 0.273615

Step-by-step explanation:

0.54723/2 = 0.273615

Dividing something by 2 means splitting the original value in half. This means that the product of the number of the original value that was divided by two is half of the original value. This means that 0.273615 + 0.273615 = 0.54723(the original value) because two halves make a whole.

Answer:

5 cm

Step-by-step explanation:

Area = length x width

40 = 8 x w

40/8 = w

5 = w

Rectangle A has area of 40cm² and length 8cm. The area of rectangle B is one-half the area of rectangle A. The rectangle have the same length. What is the width of rectangle B ?

Given:

[tex] \quad [/tex][tex] \quad [/tex] [tex] \quad [/tex] [tex] \quad [/tex][tex]{\large{\rm{{ \frac{1}{2} \times 40{cm}^{2} = 20{cm}^{2}}}}}[/tex]

Rectangle A :-

Rectangle B :-

Width :

[tex] \quad [/tex] [tex] \quad [/tex] [tex] { \large{ \sf {\frac{Area (A)}{Length (L)}}}} \longrightarrow \frac{{ \cancel{20}}^{5} }{{ \cancel{8}} ^{2}} = \frac{5}{2} [/tex]

Thus, Width of Rectangle B is 5/2 cm.

[tex] \: [/tex]

[tex] \: [/tex]

We know,

[tex] \quad [/tex] Area of Rectangle = length × breadth

➛ 8 × [tex] \frac{5}{2} [/tex]

➛ [tex] {\large{ \frac{40}{2}}} [/tex]

➛ [tex] {\large{ \frac{ \cancel{40}^{20} }{ \cancel{2}^{1} }} = { \boxed{ \red{20}}}} [/tex]

Step-by-step explanation:

Answer:

Answer:

x-intercept: (-1, 0)

y-intercept: (0, -3)

Step-by-step explanation:

The x-intercept is where the graph touches the x-axis(which is horizontal). Looking at the graph, it is observable that the graph touches the x-axis at (-1, 0).

The y-intercept is where the graph touches the y-axis(which is vertical). Looking at the graph, it is observable that the graph touches the y-axis at (0, -3).

Helpful hint: The x-intercept always has a y value of zero and the y-intercept has an x value of zero.

Answer:

x-intercept = (-1,0)

y-intercept = (0, -3)

Answer:24

Step-by-step explanation:Exponential functions are of the form f(x) = ab^x

The complete statements: Function f → the linear function f(x) = 6x and consecutive differences are constant and  function g → the exponential function g(x) =  6(2)ˣ and consecutive quotients are constant.

When b > 0 and b ≠ 1, an exponential function has the form f(x) = (b)ˣ. The base is b, and the exponent is x, just as in any exponential equation.

Linear functions have constant first differences.

Here,  if a and b is the first and second term.

Then the first difference is b-a.

Exponential functions have a constant ratio.

The ratio of first term and second term is b/a.

Let f(x) = y

Here, from the table;

y₂-y₁ = 12 - 6 = 6

y₃-y₂ = 18 - 12 = 6

y₄-y₃ = 24 - 18 = 6

Consecutive differences are constant.

And the linear function is f(x) = 6x

From the first differences, we have linear function.

To find the common ratio, b :

Let g(x) = g

Then,

g₂/g₁ = 12/6 = 2

g₃/g₂ = 24 / 12 = 2

g₄/g₃ = 48 / 24 = 2

b =2

And the exponential function g(x) = 6(2)ˣ.

Therefore, the complete statements: Function f → the linear function f(x) = 6x and consecutive differences are constant and  function g → the exponential function g(x) =  6(2)ˣ and consecutive quotients are constant.

The probability that temperature goes above 80 F =P= Success = 2/3.

The probability that the temperature goes below 80 F or 80 F =Q= Not Success= 1-2/3

=1/3

Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates the impossibility of the event and 1 indicates certainty.

Number of Days in June = 30 Days

Probability, that it will be above 80 F for 20 or more days this June

[tex]=C\left(30,20\right)P^{20}Q^{10}+C\left(30,21\right)P^{21}Q^9+C\left(30,22\right)P^{22}Q^8....+C\left(30,30\right)P^{30}Q^0.[/tex]

The best way to perform stimulation if we use a number cube with the numbers 1-6 and assign 1-4 as a temperature above 80 F and 5-6 as a temperature 80 F or below, Shows that we have marked four numbers i.e (1-4) as the temperature above 80 F, so the maximum number of days in June are of temperature above 80 F and less number of days are of the temperature, which is below 80 F or equal to 80 F.By converting it into a cube then playing the game in the classroom by collecting money from classmates by making five groups and rolling cube five times, if the number from (1-4) comes after rolling the cube you will win $5 money and if the number from (5-6) comes you win $10.The group that has the maximum correct answers wins the game.
