The value of can be get in two way.

For the column G, the total value is given by 58%.

In the row of F and column of G, the value is 31%.

Hence, the value of y is (58 - 31) = 27%.

Again, In the row of E, the total value is given by 51%.

The E-th row and H-th column shows the value 24%.

Hence, the value of y is (51 - 24) = 27%.

Answer:

-8 + 3.2z

Step-by-step explanation:

-8 + 6.45z - 3.25z

collect like terms

-8 + 3.2z

Therefore,the expression −2+6.45z−6+(−3.25z) reduces to −8+3.2z

To simplify the expression −2+6.45z−6+(−3.25z) , combine like terms by performing addition and subtraction:

Given expression:−2+6.45z−6+(−3.25z)

Group the like terms together:

(−2−6)+(6.45z−3.25z)

Combine the constants:

−8+(6.45z−3.25z)

Combine the z terms:

−8+3.2z

Therefore, after simplification, the expression −2+6.45z−6+(−3.25z) reduces to −8+3.2z

The solution to the inequality is 1 < x ≤ 8.

The given inequality can be split into two components:

The difference of 2x and 5 is greater than -3: This can be written as:

2x - 5 > -3

To solve for x, we first add 5 to both sides of the inequality:

2x > 2

Then, we divide both sides by 2:

x > 1

This indicates that the values of x which satisfy this part of the inequality are greater than 1.

The difference of 2x and 5 is less than or equal to 11: This can be written as:

2x - 5 ≤ 11

Adding 5 to both sides:

2x ≤ 16

Dividing both sides by 2:

x ≤ 8

Therefore, the common range that satisfies both parts is 1 < x ≤ 8.

Omar will buy at least 5 pounds of candy. To find this, divide his minimum spending ($40) by the cost per pound of candy ($8). The inequality solved for p is p \geq 5, meaning Omar can buy 5 or more pounds of candy.

To find out the possible number of pounds of candy Omar will buy, we can set up an inequality using the given information. We know the cost per pound of candy is $8, and Omar is going to spend at least $40 on candy. Therefore, the inequality representing the situation can be written as:

8  imes p \\(cost per pound \\ times number of pounds)\\ \geq 40 (Omar's minimum spending)

To solve for p, the number of pounds, we divide both sides of the inequality by 8:

p \geq \frac{40}{8} \Rightarrow p \geq 5

So, Omar will buy at least 5 pounds of candy. This means that the possible numbers of pounds he may buy are 5 or more.

Hours Spent at Water Park

       4              4

       5              5

       6              3

       7              4

These data could be the results of a survey whose target was to detemine how many hours people spent at a water park.

The size of the sample should be the number of tally, which is 4 + 5 + 3 + 4 = 16.

And the question most likely was made at the exit of a water park, when the people were leaving the park.

Thus, the statistical question could be How much time do people spend in the water park?

It is a statistical because the survey is made to a sample of the people who went to the water park instead to all the people. All the people who go to the water park is the population about whom you want to determine how much time they spend in the water park, but,since it is impossible to survey all the people, you need to survey a sample.

The resulting values from a sample are named statistical. The values for an entire population are named parameters. A statistical permits to draw conclusions for populations using just one or more samples, which should be random samples.

Answer:

Step-by-step explanation:

“How many hours did you spend at the water park today?” It is statistical because the responses will vary among individuals and the responses will be numeric.

if there are twins born every 250 births take your large number (2,750) and divide it by 250 to get your answer

There are 11 pairs of twins at a school with 2750 students.

Repetitive subtraction is the process of division. It is the multiplication operation's opposite. It is described as the process of creating equitable groups. When dividing numbers, we divide a larger number down into smaller ones such that the larger number obtained will be equal to the multiplication of the smaller numbers.

Given identical  twins happen once in 250 births,

total number of students in school = 2,750

to find the pair of twins divide the total number of students by 250

= 2750/250 = 11

Hence there are  11 pairs of twins in 2,750 students.

The area of the storage facility is [tex]20x^2-4x-16\:\:square\:feet[/tex].

From the attached diagram, it is clear that

The area of the storage facility in square feet can be calculated by finding the area of rectangle.

So, using the area of rectangle formula

To find the area of the storage facility, calculate the area of each shape and add them together. The correct expression is 36x^2+24x.

To find the area of the storage facility, we need to find the area of each individual shape and add them together. Looking at the diagram, we can see that the storage facility is composed of two rectangles and one square. Let's calculate the area of each shape:

Area of first rectangle = length x width = 4x(4x+4) = 16x^2+16x

Area of second rectangle = length x width = 4x(4x+2) = 16x^2+8x

Area of square = side x side = (2x)^2 = 4x^2

To find the total area, we add the areas of the three shapes:

Total area = (16x^2+16x) + (16x^2+8x) + 4x^2 = 36x^2+24x

Therefore, the correct expression that represents the area of the storage facility is 36x^2+24x, which is option B.

Hope this helps.

The required simplified value of the given number (-5)² would be 25.

A perfect Square is defined as an integer multiplied by itself to generate a perfect square, which is a positive integer. Perfect squares are just numbers that are the products of integers multiplied by themselves.

When an expression can be seen as the difference of two perfect squares, i.e. a² -b², we can factor it as (a+b) (a-b).

The number is given in the question,

(-5)²

We have to determine the simplified value of the given number (-5)².

⇒ (-5)²

⇒ (-5)(-5)

⇒  5 × 5 × (-1) × (-1)

⇒ 25 × 1

⇒ 25

Thus, the required simplified value of the given number (-5)² would be 25.

Answer:

26/100 which is simplified to 13/50

Step-by-step explanation:

you have to get equal denominators so multiply 2/10 by 10 on top and bottom to get 20/100 then you can add 6/100 plus 20/100 which is 26/100 . denominators stay the same 26/100 can be simplified to 13/50

The sum of 2/10 and 6/100 is 13/50.

To find the sum of 2/10 and 6/100, we'll first find a common denominator and then add the fractions together.

The common denominator for 10 and 100 is 100, as it is the smallest multiple that both denominators can evenly divide into.

Now, we'll rewrite both fractions with the common denominator of 100:

2/10 = (2/10) * (10/10) = 20/100

6/100 = 6/100

Now that both fractions have the same denominator, we can add them together:

20/100 + 6/100 = (20 + 6)/100 = 26/100

Now, we have the sum of the fractions as 26/100. To simplify this fraction, we can divide both the numerator and denominator by their greatest common divisor, which is 2:

(26 ÷ 2) / (100 ÷ 2) = 13/50
