Subtraction, 989.99 - 311.25 = $678.74 (answer)

$678.74 because you need $989.99 but you only have $311.25 so you need to subtract what you have and what you need( $989.999 $311.25 ) and you would get $678.74 now to check you have to add what you have and what you need($678.74 $311.25) and get $989.99

Find the value of x Using parallel cut by the transversal (show your work)
V125BC [204]

Answer:In the following diagram, two parallel lines are cut by a transversal. What is the value of x x? Solution: The two angles 3x −15 3 x − 15 and 2x +7 2 x + 7 are equivalent. That is: 3x −15 = 2x +7 3 x − 15 = 2 x + 7

12x +7 < −11 OR 5x −8 > 40
r-ruslan [8.4K]

For this case we must resolve each of the inequalities and find the solution set.

Inequality 1:

12x + 7

We subtract 7 from both sides of the inequality:

12x

We divide between 12 on both sides of the inequality:

x

Thus, the solution is given by all values of x less than- \frac {3} {2}.

Inequality 2:

5x-8> 40

We add 8 to both sides of the inequality:

5x> 40 + 8\\5x> 48

We divide between 5 on both sides of the inequality:

x> \frac {48} {5}

Thus, the solution is given by all values of x greater than\frac {48} {5}.

The solution set is given by:

(-∞, - \frac {3} {2}) U (\frac {48} {5},∞)

Answer:

(-∞, - \frac {3} {2}) U (\frac {48} {5},∞)

What are the relative frequencies, to the nearest hundredth, of the rows of the two-way table? Drag and drop the values into the
quester [9]

Answer:

.25             .75

.44            .56

Step-by-step explanation:

To find the relative frequency, we take the part over the total.

Since this  is a relative frequency table, the total for each row is 1

Group 1 A  = 15/ (15+45) = 15/60 = .25

Group 1 B = 45/(15+45) = 45/60 = .75

Group 2 A = 20 /(20+25) = 20/45 =.44

Group 2B = 25/(20+25) = 25/45 =.56
