Answer:

4 is right yur

Step-by-step explanation:

Mean = 110

Sample size = 45

Standard deviation = 6

Z score for 90% is 1.645 ( from Z-table).

Lower Limit = Mean - Z(SD/√Sample size))

Lower limit = 110 - 1.645(6/√45)

Lower limit = 108.5

Upper Limit = Mean + Z(SD/√Sample size))

Lower limit = 110 +1.645(6/√45)

Lower limit = 111.5

The interval is (108.5, 111.5)

The required number of trays.

Explanation:

Let [tex]x[/tex] be the required number of trays.

Total quantity of muffins in [tex]x[/tex] trays is [tex]6x[/tex].

Total quantity of required muffins is:

[tex]8\times 3=24[/tex]

Answer:

5 inches

Step-by-step explanation:

V = (b² h) ÷ 3

Given that V = 25 and h = 3:

25 = (b² × 3) ÷ 3

25 = b²

b = 5

Therefore, the length of the base's sides is 5 inches.

The expression to show how many hours Kyle practices is 2.5t, where t equals the number of hours Grant practices.

If Kyle practices 2.5 times as many hours as Grant does, and we let t represent the number of hours Grant practices, then the expression to show how many hours Kyle practices would simply be 2.5t. This is because we are given the ratio of Kyle's practice time to Grant's practice time, which we can use to express Kyle's practice time in terms of Grant's.

Answer:

-6/5

Step-by-step explanation:

solution;

let,the number be x,

product of twice of x and six = the difference

difference of eleven times x and 6/5

or, (2x×6)=(11×x)-(6/5)

or, 12x = 11x - 6/5

or, 12x - 11x = -6/5

therefore,x =-6/5

Therefore, the number required is (-6/5) whose product of twice a number and six is the same as the difference of eleven times the number and 6/5 .

Answer:

8.6

Step-by-step explanation:

basically just do the order of operations

Median: The middle number when all the numbers are listed in order.

To find the median of the data set shown here, we can first start by putting all the numbers in order from least to greatest.

Least to greatest - 5, 5, 7, 10, 13

Next, we locate the number that is exactly in the middle and if there is no number exactly in the middle, we find the two numbers and find halfway point between them.

The number that is exactly in the middle of the data set is 7 so our median is 7.

Step-by-step explanation:

8x-2-(9x+2)

8x-2-9x-2

-x-4

Function h(x) = f(x) – g(x) = -x - 4

Function, in mathematics, an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

Given functions

f(x) = 8x – 2

g(x) = 9x + 2

h(x) = f(x) – g(x)

h(x) = (8x – 2) - (9x + 2)

h(x) = 8x - 2 -9x - 2

h(x) = (8x - 9x) + (-2 - 2)

h(x) = -x - 4

Hence, h(x) = -x - 4

Answer:

6s

Step-by-step explanation:

sx6 = 6s

Using a system of equations, it is found that:

If Ben is x years old, the expression 3x + 5 gives the sum of Ben’s and Teresa’s ages. If Ben is 7 years old, the sum of Ben’s and Teresa’s ages is 26 years.

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

In this problem, the variables are given by:

Teresa’s age is 5 years more than twice Ben’s age, hence:

y = 2x + 5

The sum of their ages is:

x + y = x + 2x + 5 = 3x + 5.

Ben is 7 years old, hence the sum is given by:

3(7) + 5 = 26.

Then:

If Ben is x years old, the expression 3x + 5 gives the sum of Ben’s and Teresa’s ages. If Ben is 7 years old, the sum of Ben’s and Teresa’s ages is 26 years.

More can be learned about a system of equations at https://brainly.com/question/24342899

The sum of Ben's and Teresa's ages is represented by the expression 3x + 5, and when Ben is 7 years old, their total age is 26 years.

The expression to represent the sum of Ben's age and Teresa's age, given that Ben is x years old and Teresa's age is 5 years more than twice Ben's age, is 2x + 5 + x. This can also be simplified to 3x + 5.

When Ben is 7 years old, we plug in the value 7 for x in the simplified expression to calculate the sum of their ages: 3(7) + 5, which equals 21 + 5.

Therefore, the sum of Ben's and Teresa's ages when Ben is 7 years old is 26 years.

Answer:

-9

The problem:

If h(x)=-7x and h(x)=63, the what is the value of x?

Step-by-step explanation:

h(x)=-7x

You are asked to find x such that h(x)=63.

So you are solving:

h(x)=63 for x:

-7x=63

Divide both sides by -7:

x=63/-7

Simplify:

x=-9

Let's check:

h(x)=-7x

h(-9)=-7(-9)

h(-9)=63

So -9 is the answer.

The value of x in the equation y = 9 + 3x for a given y value can be found by rearranging the equation to x = (y - 9) / 3, and substituting the desired y value.

The subject of this question is determining the value of x in the equation y = 9 + 3x. In this equation, the b term is 9 and the m term is 3, representing the y-intercept and the slope respectively. To find the value of 'x' that gives a specific 'y' value, one must rearrange the equation to solve for 'x': x = (y - 9) / 3. For example, if we wanted the y value to be 15, we would substitute into the equation and find that x = (15 - 9) / 3 = 2

Answer:

Step-by-step explanation:

v= 1/3 bh

multiply by : 3

3v = bh

dividid by b : h = 3v/b

To solve for h in the equation v = (1/3)bh, you need to isolate h on one side. Multiply both sides by 3 to eliminate the fraction, then divide both sides by b to solve for h.

To solve the equation v = (1/3)bh for h, we need to isolate h on one side of the equation.

First, we can multiply both sides of the equation by 3 to get rid of the fraction: 3v = bh.

Next, to solve for h, we divide both sides of the equation by b. This gives us the final answer: h = 3v / b.

Now, we are given that their sum is 441.

So,

(x) + (x+1) + (x+2) = 441

3x + 3 = 441

3x = 438

x = 438/3

x = 146

The most accurate summary of nationalism in the Middle East during the 1920s is option c: Broken Western promises and conflicting nationalist goals set the nations of the former Ottoman Empire on the path to conflict.

After World War I, the Middle East experienced a surge in nationalist aspirations as the Ottoman Empire collapsed. However, the promises of self-determination made by Western powers, particularly through the Sykes-Picot Agreement and the Balfour Declaration, were largely unfulfilled.

This led to widespread discontent and conflicting nationalist goals, creating tensions and setting the stage for regional conflicts. Additionally, the imposition of artificial borders and the interference of Western powers further fueled nationalist sentiments, contributing to a turbulent period of political, social, and economic unrest in the Middle East during the 1920s.

The failure of Western promises and the clash of nationalist ambitions indeed played a pivotal role in shaping the trajectory of the region.

Answer:

depending on the national/ regional legal provisions in favour of the tax contributor where either the work is provided/ the computer was aquired/ placed, repaired/ the repair company has declared fiscal residency the cost ( in hours) could be determined by 0.07 ( 40h)

Final answer:

The expression 0.07(40h) in the equation represents the amount of tax Deborah has to pay. 0.07 stands for the 7% tax rate applied to the cost of repair, which is denoted by 40h.

Explanation:

The student has asked to identify the part of the expression in 0.07(4 0h) + 4 0h, which represents the tax Deborah has to pay for her computer repairs, where h represents the number of hours it takes to repair the computer. In this expression, the tax component is given by 0.07(40h).

The 0.07 represents the 7% tax rate on the cost of repair. The cost of repair, before tax, is represented by the term 40h. When you multiply 40h by 0.07, you are calculating 7% of the repair cost which equates to the tax amount.
