Answer:

answer 1 and 4

Step-by-step explanation:

1:because you would want to add the number of dots above each age in the dot plot to find the number of players on the team: 2 + 1 + 3 + 2 + 3 + 2 = 13.

2:The median appears clearly on the box plot at the line within the box: 10.

so there for its answer 1,4 hope this helps!

The sum of two numbers is 65 and the difference of those two numbers is -18

joja [24]

Answer:

41.5

23.5

Step-by-step explanation:

Let's start by calling the two numbers we are looking for x and y.

The sum of x and y is 65. In other words, x plus y equals 65 and can be written as equation A:

x + y = 65

The difference between x and y is -18. In other words, x minus y equals -18 and can be written as equation B:

x - y = -18

Now solve equation B for x to get the revised equation B:

x = -18 + y

Then substitute x in equation A from the revised equation B and then solve for y:

x + y = 65

-18+y+y=65

-18 + 2y = 65

2y = 83

y = 41.5

Now we know y is 41.5. Which means that we can substitute y for 41.5 in equation A and solve for x:

x + y = 65

x + 41.5= 65

X = 23.5

DIfference : 23.5 - 41.5 = 18

Sum: 41.5 +23.5 = 65

Hence, The two number are 23.5 and 41.5

You have to read 1012

Lyrx [107]

We read $3\frac{1}{2}$ pages .

Step-by-step explanation:

Correct Question: You have to read 10 1/2 pages for homework. So far, you have read 1/3 of the assignment. How many pages did you read?

We have , to read 10 1/2 pages or $10\frac{1}{2}$ pages for homework . Till now we have read 1/3 of the assignment or $\frac{1}{3}$ of the assignment . We need to find How many pages did you read . Let's find out:

Basically we read 1/3 part of the 10 1/2 pages assignment i.e.

⇒ $10\frac{1}{2}(\frac{1}{3})$

⇒ $\frac{20+1}{2}(\frac{1}{3})$

⇒ $\frac{21}{2}(\frac{1}{3})$

⇒ $\frac{3(7)}{2}(\frac{1}{3})$

⇒ $\frac{7}{2}$

⇒ $3\frac{1}{2}$ pages

Therefore , We read $3\frac{1}{2}$ pages .

m∠CED = 180° − m∠DEB= 90 degrees, by reason corresponding angles of parallel lines are congruent
m∠CFD = 180° − m∠AFD = 90 degrees by reason corresponding angles of parallel lines are congruent

Ken has a rectangular shaped vegetable garden that is 15 feet by 9 feet. He would like to increase the length and width by the s

tigry1 [53]

The current area is 15 x 9 = 135 square feet.

He wants to increase both the length and width by X:

Set up an equation:

(15 +x) * (9 +x) = 135 * 2

Simplify :

x^2 + 24x + 135 = 270

Subtract 270 from both sides:

x^2 + 24x - 135 = 0

Use the quadratic formula to solve for x:

-24 +/- √(24^2 - 4(1*-135) / 2*1

x = 4.7 or -28.7

The answer has to be a positive value, so x = 4.7 feet.

A snack food manufacturer buys corn for tortilla chips from two cooperatives, one in Iowa and one in Illinois. The price per uni

aleksandrvk [35]

Answer:

a. x1 = No. of units to purchase from Iowa

x2 = No. of units to purchase from Illinois

b. Min 6x1 + 5.5x2

c. x1 + x2 ≥ 12000

x1 ≤ 8000

x2 ≥ 6000

Step-by-step explanation:

a. We can consider the variables x1 and x2 as:

x1 = No. of units to purchase from Iowa

x2 = No. of units to purchase from Illinois

b. Price per unit of Iowa corn = $6

Price per unit of Illinois corn = $5.5

Objective function that would minimize the total cost can be written as:

Min 6x1 + 5.5x2

c. The manufacturer needs at least 12000 units of corn which means that the combined number of units from Iowa and Illinois must be greater than or equal to 12000. So, we can write:

x1 + x2 ≥ 12000

The Iowa cooperative can supply up to 8000 units which means that the value of x1 must not be greater than 8000. So, we can write:

x1 ≤ 8000

Similarly, the Illinois cooperative can supply at least 6000 units which means that the value of x2 must not be less than 6000. So, we can write:

x2 ≥ 6000.

The constraints for these conditions are:

x1 + x2 ≥ 12000

x1 ≤ 8000

x2 ≥ 6000
