The value of an item is greater than or equal to 5. This statement is represented by the inequality [tex]x\geq 5[/tex] .

An inequality is a mathematical relation which compares the values of two different entities.

The various symbols used in expressing inequalities are

Linear inequalities in one variable are represented on the number line.

For example: a>100 represents all numbers greater than 100 along the number line

Linear inequalities in two variables are represented as a region in a cartesian plane.

For example: 2x+3y<6 represents a region below the straight line 2x+3y=6.

The given statement denotes that the value of the item is greater than or equal to 5.

Therefore the required inequality is : [tex]x\geq 5[/tex].

Answer: No solution

Step-by-step explanation:

5r + 5 = 3(5r - 4) - 10r  Do multiplication

5r + 5 = 15r - 12 - 10r  combine like terms

5r + 5 = 5r - 12        This is impossible. 5r cannot equal 5 and 12 meaning there is no value of r that makes this equation true so there's No Solution.

You could continue

5r + 17 = 5r

Answer:

No, because there is an output value with more than one input value.

Step-by-step explanation:

If you are using the same function equation, than you should not get the same output if you use two different inputs.

The linear equation in terms of the variable R is determined as x = R/10.

Given data:

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

The given equation is:

R = x + 9x

First, let's combine the like terms on the right side of the equation:

R = 1x + 9x

R = 10x

Now, we want to solve for x. To isolate x, divide both sides of the equation by 10:

R/10 = x

So, the solution for x is:

x = R/10

Hence, the expression for in terms of R is x = R/10.

The slope of a line is written as a fraction of the vertical distance to the horizontal distance. The line drops down from (0,1) to (4,-2). This is a vertical distance of -3 and a horizontal distance of 4. The slope if the fraction -3/4.

Answer:

[tex] \sf \: b) \: \frac{ - 3 \: }{ 4} [/tex]

Step-by-step explanation:

The coordinates are,

→ x1 = 4, y1 = -2

→ x2 = -4, y2 = 4

Formula we use,

→ Slope(m) = (y2 - y1)/(x2 - x1)

Now the required slope will be,

→ m = (y2 - y1)/(x2 - x1)

→ m = (4 -(-2))/(-4 - 4)

→ m = (4 + 2)/-8

→ m = 6/-8

→ [ m = -3/4 ]

Hence, the option (b) is correct.

Answer: There are 12 volleyball players

Step-by-step explanation:

If the ratio of basket to volleyball players is 5:2 and there are 30 known basket ball players that means the ratio can be written as 30:x.

If 30 is 5 parts (5x) and volleyball players is 2 parts (2x)  we need to figure out the value of 1 part (x)

This can be done by

5x=30

x=6

Now we know what 1 part is, we can now use that two figure out 2 parts

2x or 2(6)

2(6) = 12

So the ratio is 30:12. This can be confirmed by dividing both sides of the radio by 6 to get 5:2

Step-by-step explanation:

The total number of notebooks on Sasha's notebook is 2c - 6.

Unitary method:

The unitary method is used to solve problems by first determining the value of a single unit and then multiplying that value by the required value.

So, this method is basically used to find the value of a unit and then the value of a required number of units.

Given,

Sasha has c green notebooks.

She has 6 fewer red notebooks then green notebooks.

So, here we need to find how many notebooks does Sasha have in all.

We know that.

Sasha has c green notebooks.

The number of red notebooks on her is  

=> c − 6.

Here Sasha has either green or red notebooks.

The total number of notebooks on Sasha's notebook is  

=> c + c − 6

The sample proportion, p-hat, of engineers who have master's degrees is   68.5% out of 200 engineers.

p-hat proportion:

In this proportion,  "p" denotes the probability of a certain event occurring or a certain parameter being true for a certain population, but when a population is large, it may be impractical or impossible to measure it directly. So, we have used the proportion for that cases.

The general form for calculating p-hat proportion is,

[tex]\hat{p}=\frac{x}{y}[/tex]

where

x  is the number of successes in the sample, and

y is the size of the sample.

Given,

In a random sample of 200 engineers, 137 have a master's degree.

Here we need to find the the sample proportion, p-hat, of engineers who have master's degrees

According to the question,

x = 137 (number of successes in the sample)

and y = 200 (size of the sample)

Now apply the value on the formula then we get,

[tex]\hat{p}=\frac{137}{200}[/tex]

So, the value of p-hat is

[tex]\hat{p}=0.685[/tex]

The results are usually reported as a percentage, which in this case would be

=> 0.685 x 100 = 68.5%

Therefore, the sample proportion, p-hat, of engineers who have master's degrees is 68.5% out of 200 engineers.

The population parameter being estimated is the confidence coefficient.

The confidence coefficient is the confidence level stated as a proportion, rather than as a percentage. For example, if you had a confidence level of 99%, the confidence coefficient would be . 99. In general, the higher the coefficient, the more certain you are that your results are accurate.

probability is the likelihood that something will occur. When we don't know how an event will turn out, we can discuss the likelihood or likelihood of several outcomes. Statistics is the study of events that follow a probability distribution.

The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.

Hence, The probability that the interval estimation procedure will generate an interval that does not contain the actual value of the population parameter being estimated is the confidence coefficient.

Part(A) Leslie's initial investment was $500 and

Part(B) The quarterly interest rate is 10.4 %

What is compound interest?

Compound interest is the interest calculated on the principal amount , which also considers all the accumulated interest of previous periods of deposit or loan.

If P is the principal amount and rate of compound interest is r  then after t years of time , the present amount (if the interest is compounded annually) will be = P(1+(r/100))^n

If the interest is compounded quarterly, then the present amount be A

Where A = [tex]P (1+\frac{r/4}{100} )^{4t}[/tex]

Given that Leslie invests in a bank that earns interest quarterly , and account balance after t years is given as 500(1.026)^(4t)

A= [tex]P (1+\frac{r/4}{100} )^{4t} = 500(1.026)^{4t\\[/tex]

Comparing both sides we get P = 500

And 1+(r/400)=1.026

(r/400)=1.026-1

(r/400)=.026

r=400(0.26) = 10.4 %

Therefore , Leslie's initial investment was $500 and the quarterly interest rate is 10.4 %

The current percentage in comparison to in the year 2000 is 88.22%.

We are given the percentage of death in the year 2000, 2015 and the difference. Now, we have to find the percentage of donors between change and the original deaths in the year 2000.

To find this, we will use the following formula -

Percentage change = Difference between the percentage change in the year 2000 to 2015 ÷ Percentage of deaths in the year 2000 ×100

Now, keep the values in formula to find the percentage change.

Percentage change = [tex]\frac{8.24}{9.34} *100[/tex]

Performing division to find the percentage change

Percentage change = 0.882*100

Further performing multiplication to get the answer in the form of percentage
