Step-by-step explanation:

Set of Data (Prioritized):

3.8, 3.9, 4.0, 4.1, 4.2

To find the mean:

Add up all the scores and divide the total by the number of scores.

(3.8 + 3.9 + 4.0 + 4.1 + 4.2) ÷ 5

PLEASE HELP ASAP Greg wants to earn more than $50 trimming trees. He charges $6 per hour and pays $4 In equipment fees. What are the possible numbers of hours Greg could trim trees? Use t for the number of hours. ​

Answers

Answer:

Step-by-step explanation:

h = number of hours, e = number of equipment

50 > 6t - 4e

I tried my best

Answer:

Greg could trim trees anywhere more than 7.67 hours for more than $50.

Step-by-step explanation:

First, set up the equation. Since he doesn't have a fixed number of dollars to earn (it is more than $50, not just $50), this would be an inequality.

50 < 6t - 4

50 is the principle goal, 6t because t is hours, and he gets $6 every hour, and - 4 because he pays a one time fee for equiment.

Then, you solve the inequality the way you would with one-variable inequalities:

50 < 6t - 4

46 < 6t

7.67 < t

The scores for today's math quiz are 75, 95, 60, 75, 95, and 80. Explain the steps needed to create a histogram for the data. PLEASE MAKE THE ANSWER SCHOOL APPROPRIATE.

Answers

Answer:

Chill, it ain't complicated

Step-by-step explanation:

A histogram is basically a bar graph but there's no space between the bars.

The graph has to be the dependent component (the score) against the independent component (the number of students who took the math quiz)

Depending on your size of paper pick a simple scale (1 cm could be either 5% or 10%)

Leave some space between the y (vertical) axis and the first bar.

Do them in the order they appear, i.e 75, 95... 80

As an estimation we are told 5 miles is 8 km.
Convert 84 km to miles.

Suppose the movie theater you work at sells popcorn I'm three different sizes. A small cost $2, a medium cost $5, and a large cost $10. On your shift, you sold 250 containers of popcorn and brought in $1726. You sold twice as many large containers as small ones. a. How many of each popcorn size did you sell? B. How much money did you bring in from selling small size containers?

Answers

Let, number of small, medium and large popcorn sold are s, m and l respectively.

So, s + m + l = 250    ....1)

Also, l = 2s     ....2)

Total sum = $1726 = 2s + 5m + 10l     .....3)

Putting value of l from 2) to 1) is :

s + m + 2s = 250

m + 3s = 250    

m = 250 - 3s      ....4)

Putting value of m and l in terms of s in equation 3)

We get :

2s + 5( 250 - 3s ) + 20s = 1726

7s = 1726 - 1250

s = 68

l = 136

m = 250 -3(68) = 46

Now,

[tex]P_s=68\times 2 = \$136\\\\P_m = 46\times 5 = \$230\\\\P_l = 136\times 10 = \$1360[/tex]

Hence, this is the required solution.

Answers

Answer:

Since the diagonal is the maximum dimension in a square, if the length of the diagonal is less than the diameter of the circle which is 9cm, then the square can fit inside the circle.

Step-by-step explanation:

Given:

A circle that has a diameter of 9cm

Square that has a side length of 5cm

Find:

First, find the length of the diagonal of the square.

Solve:

Let D represents the length of the diagonal of square

Using the Pythagora's Theorem

D² = side² + side²

D² = 2side²

Since the length of square is equal to 5cm then,

D² = 2 × 5²

D² = 50

√D² = √50

D = √25 ×2

D = 5√2

D = 7.07106781187

D = 7.07

We can see that the length of the diagonal of the square is less than the diameter of the circle, so the square can fit inside the circle.

The inequality expressions x < -2 and x < -5 are used to illustrate unequal values

How to determine the number lines

Number lines are used to represent numbers at regular intervals

The expressions are given as:

x < -2 and x < -5

The above expression means that:

x is less than -2 and x is less than -5

Both statements cannot always be true.

However, x is less than -5 is true for the expressions x < -2 and x < -5

So, we represent the inequality x < -5 on the number line
