The total number of students is 24 and the total number of boys is 6, therefore

Number of girls = 24 – 6 = 18

Therefore the ratio of the boys to girls is

Number of boys/ number of girls = 6/18 ~ 1/3

The ratio suggests that there is 1 boy for every 3 girls

To solve this, all we need to do is substitute the values of x and y at which they are the same into each equation and see if it holds true.

A.

Since this is not true, we can scratch choice A off our list.

B.

This is true, so choice B is one of the correct answers.

C.

This equation also holds true, so choice C is also correct, but let us do the final option just for the sake of completion.

D.

This is obviously not true, so choice D is also false.

**The correct answer choices are B and C.**

QUESTION POSTED AT 18/01/2020 - 12:54 PM

**Answer:**

Option D. (120, 80, 40)

**Step-by-step explanation:**

Let the cost of 3 baseball cards bought by Andrew are $x, $y and $z.

Now we will form the equations to find the unknown values of x, y, and z.

**Statement 1** - Andrew bought 3 baseball cards for $240

Equation will be **(x + y + z) = 240 --------(1)**

**Statement 2** - Jack offered a deal to buy the first card for the double of its original value along with the second card for $320.

Equation will be **2x + y = 320 --------(2)**

**Statement 3** - Jack offered another deal to buy first card for the double of its original value along with third card for $280

Equation formed** 2x + z = 280 ------(3)**

Now we can solve these equations to get the values of x, y and z.

**From equation 2**

y = 320 - 2x

**From equation 3**

z = 280 - 2x

Now we can replace the values of y and z in equation number 1.

Equation 1 becomes after substitution of y and z values

x + (320 - 2x) + (280 - 2x) = 240

Now we will group the similar terms

(x - 2x - 2x) + (320 + 280) = 240

-3x + 600 = 240

-3x = 240 - 600

-3x = - 360

x =

x = 120

Now we put x = 120 in the value of y

y = 320 - 2x

y = 320 - 2×120

= 320 - 240

= 80

Similarly we put the value x = 120 in value of z

z = 280 - 2x

= 280 - 2×120

= 280 - 240

= 40

So the original values of 3 baseball cards are (120, 80, 40)

**Option D**. will be the answer.

40%

__Explanation__

A parentage value is a value that has been compared to 100.

Percentage = (change in the value)/(the original value) × 100%

= (35-25)/25 × 100%

= 10/25 × 100%

To compare the two classes, the Coefficient of Variation (COV) can be used. The formula for COV is this:

C = s / x

where s is the standard deviation and x is the mean

For the first class:

C1 = 10.2 / 75.5

C1 = 0.1351 (13.51%)

For the second class:

C2 = 22.5 / 75.5

C2 = 0.2980 (29.80%)

The COV is a test of homogeneity. Looking at the values, the first class has more students having a grade closer to the average than the second class.

The *correct answer* is:

d.) 1040-A

**Explanation**:

A 1040-EZ is used if you are single or married filing jointly, make less than $100,000, and have no adjustments to your income. Sandy and Alex wish to deduct student loan interest, so they cannot use this form.

The next one is the 1040-A. This one can be used to deduct student loan interest, so this would be the one they should use. It is the simplest form that will allow them to claim what they wish to claim.
