is (0,1) a solution of -10x+4y≥-4

Answer: Yes, they are mutually exclusive. You cannot have 2+ heads and 0 heads at the same time. They are not independent. The result of 2+ heads nullifies the chance that 0 heads are flipped!

Answer:

Ans is 120

Step-by-step explanation:

25 x 4 is a 100

therefore multiply 4 by 30 to find the 100%

or the ? value that makes the statement true

Ans is 120

Answer:

25% of 120 is 30

Step-by-step explanation:

25% = 0.25

0.25 y = 30

y= 30/0.25

y= 120

A prediction based on the data is reliable, because the means of the samples are close together.

Step-by-step explanation:

Test approved

The most accurate statement is A. A prediction based on the data is reliable, because the means of the samples are close together.

Mean of a set of data is defined as the average of all the values. It gives the exact middle point of the data set.

Given three data sets.

All the samples have 10 data points.

Number of data points = 10

Mean of sample 1 = 9.1

Mean of sample 2 = 9.4

Mean of sample 3 = 8.9

We can see that the mean of the three samples is so close to each other.

So the data is reliable.

Hence the option is A.

Answer: number of girls = 21 & number of boys = 15

                     21 - 15 = 6 ( the difference is 6 )

Step-by-step explanation:

Answer:

add the ratios together. this gives 5+7 which is 12. divide 36 by 12, this gives 3. this tells us it's three students for every value of the ratio, so the ratio is 5(3):7(3). it becomes 15 boys to 21 girls. to find out how many more girls, we subtract 15 from 21. our answer is 6.

Answer:

1). $27.50 2). $200

Step-by-step explanation:

1). 100 - 2(35) - 2.50 = x so x= $27.50

2) x * 7 + 345 = 1,745.00

x= (1,745 - 345) / 7

x= $200

Answer:

Are you looking to calculate whether 2/10 is greater than 11/20? One of the most common calculations you'll make in math is to compare fractions. In this really simple guide, we'll teach you how to compare and determine if 2/10 is bigger than 11/20 and walk you through the step-by-process of how the calculation is made.

As we always do in these tutorials, let's recap and remind ourselves that the number above the fraction line is called the numerator and the number below the fraction line is called the denominator.

Depending on the math problem you want to solve, there are two methods to calculate if 2/10 is larger than 11/20:

Convert the fractions to have the same denominator

Convert the fractions to a decimal number

Let's start with the first method: converting the fractions to the same denominator. First, we'll set up 2/10 and 11/20 side by side so they are easier to see:

Converting Denominator

2

10

&

11

20

Our denominators are 10 and 20. What we need to do is find the lowest common denominator of the two numbers. This is the smallest number that can be divided by both 10 and 20. In this case, the lowest common denominator is 20.

If we multiply the first denominator (10) by 2 we will get 20. If we multiply the second denominator (20) by 1 we will also get 20. We also need to multiply the numerators above the line by the same amounts so that the fraction values are correct:

2 x 2

10 x 2

11 x 1

20 x 1

This is what 2/10 and 11/20 looks like with the same denominator:

4

20

&

11

20

Now that these fractions have been converted to have the same denominator, we can clearly see by looking at the numerators that 4 is NOT greater than 11 which also means that 2/10 is NOT greater than 11/20.

Converting to Decimal

You can also compare these fractions by first converting them to decimal format. This is a lot faster than working out the lowest common denominator. All we do here is divide the numerator by the denominator for each fraction:

2/10 = 0.2

11/20 = 0.55

Now that these fractions have been converted to decimal format, we can compare the numbers to get our answer. 0.2 is NOT greater than 0.55 which also means that 2/10 is NOT greater than 11/20.

Hopefully this tutorial has helped you to understand how to compare fractions and you can use your new found skills to compare whether one fraction is greater than another or not!

[tex]After\ Tax = 7490[/tex]

Step-by-step explanation:

Given

[tex]Days = 2[/tex]

[tex]Rent = 3500[/tex] daily

[tex]Tax = 7\%[/tex]

Required

The total amount paid

For a day, he pays (without tax)

[tex]Rent = 3500[/tex]

For 2 days, he pays

[tex]Rent = 3500 * 2[/tex]

[tex]Rent = 7000[/tex]

After tax, his bills is:

[tex]After\ Tax = Rent + Rent * Tax[/tex]

[tex]After\ Tax = 7000 + 7000* 7\%[/tex]

[tex]After\ Tax = 7000 + 490[/tex]

[tex]After\ Tax = 7490[/tex]
