The frequency table below shows the amount of left and right handed people there are in the 3rd grade. How many total right handed students are there?

Answer:

24 cars

Step-by-step explanation:

Given

[tex]Red:Blue = 3:2[/tex]

[tex]Cars = 40[/tex]

Required

Determine the number of red cars

Number of red cars is calculated using:

[tex]Red\ Cars = \frac{Red\ Ratio}{Total\ Ratio} * Cars[/tex]

[tex]Red\ Cars = \frac{3}{3 + 2} * 40[/tex]

[tex]Red\ Cars = \frac{3}{5} * 40[/tex]

[tex]Red\ Cars = \frac{3 * 40}{5}[/tex]

[tex]Red\ Cars = \frac{120}{5}[/tex]

[tex]Red\ Cars = 24[/tex]

Answer:

xy = 16

Step-by-step explanation:

[tex]\frac{1}{x}[/tex] + [tex]\frac{1}{y}[/tex] = [tex]\frac{1}{2}[/tex] ( multiply through by 2xy to clear the fractions )

2y + 2x = xy ← factor out 2 from each term on the left side

2(y + x) = xy

substitute x + y = 8 into the left side

2(8) = xy , that is

xy = 16

Answer:

x=1 and y=−1

Counting the terms already shown, we would need 59 more. Since each term adds ten, let's make each term 10 added to the previous.

The value of i, the interest rate per period(monthly here)  that should be used in the considered formula is given by: Option B: 0.71

If we're given that:

Then, we get:

[tex]P = P_v\left(\dfrac{i}{1-(1+i)^{-n}}\right)[/tex]

For this case, we're provided that:

i = interest rate per period

And we have:

Interest rate compounding monthly = 8.5%

The interest rates are usually given for annual basis. Since i represents the rate per period, which is monthly here, thus, we will convert the rate 8.5% from annually to monthly.

Since 1 year = 12 months,

so 8.5% per year compounding monthly = (8.5/12)% per month compounding monthly

Thus, i = interest per period = interest per month = 8.5/12≈ 0.71 (in percentage)

Thus, the value of i, the interest rate per period(monthly here)  that should be used in the considered formula is given by: Option B: 0.71

Step-by-step explanation:

as you want to find the square root of 100, by using a calculator you will find out that it is 10, also in other way you can check whether it is true by multiply 10 with 10, which you will get 100. in other way, square root of 100 means what value times with what value will get 100

Hey there!

First of all, what is this "√" sign?

It means "square root"

Wow, numbers have square roots? Yes.

The square root of a number is the opposite of squaring a number.

Squaring a number simply means multiplying it times itself.

So taking the square root of a number is the opposite of squaring a number.

So, we have

[tex]\bold{\sqrt{100} }[/tex]

What is the square root of 100? in other words, what number times itself equals 100?

That's right, 10.

Hence, the answer is:

The equation 4x+8 = -2-2+5x has only one solution x=12.

Given equation is:

4x+8 = -2-2+5x

An equation is an operator (denoted by =) that equates the two expressions.

On bringing variables to the left side and constants on the right side

4x-5x = -2-2-8

-x = -12

x =12

Therefore, the equation 4x+8 = -2-2+5x has only one solution x=12.

Answer:

To reduce bias when estimating mean commuting time

Step-by-step explanation:

Given that the selection of adults is based on the three strata found in the region; urban, suburban, and rural areas where the population and proportion of adults commuting to work is progressively decreasing, using a uniform number or sample size will not increase sample error as there are more commuters in the urban areas than in the suburban or rural areas, likewise, there are more commuters in the suburban area than in the rural areas, and as such the proportion of those sampled in the urban  areas should be more than those surveyed in the suburban while those surveyed in the suburban areas should be more than those surveyed in the rural areas to reduce bias when estimating the mean as there will be more general representation.

Z-score of given data comes to be -5.30.

It is given that

Population mean μ= 310

Standard deviation σ= 20

Mean of sample data X= 295

Sample size n= 50

A Z-score is a numerical measurement that describes a value's relationship to the mean of a group of values.

For a hypothesis test

Z-score = (X-μ)/(σ/√n)

Where, X = observed value

μ= mean

σ = standard deviation

n =sample size

Z-score of above data = (295-310)/(20/√50)

Z-score = -5.30

Therefore, Z-score of given data comes to be -5.30.
