we need to calculate [tex]\Delta = \sqrt{b^2-4ac}[/tex]

and if [tex]\Delta[/tex] is positive we have 2 distinct roots

if [tex]\Delta[/tex] is 0 then we have two identical roots.

Nico has $11.50 deducted from his weekly paycheck for health care. If his employer pays 90% of the premium, how much is his annual premium ?

A) $5980

B) $2990

C) $665

D) $115

Answers

Answer:

Nico's annual premium is A) $5980.

Nico has $11.50 deducted from his weekly paycheck for health care.

So,

Nico's annual deduction are:

Since there are 52 weeks in a year.

So,

11.50*52=$598

His employer pays 90% of the premium, means Nico pays 10%.

And $598 is 10% of total annual premium.

Let annual premium is x.

10%of x =$598

10/100*x=$598

x=$598*10

x=$5980

Hence, Nico's annual premium is $5980

Drawing a Card: If one card is drawn from a deck, find the probability of getting a red 6. Leave your answer in non reduced fraction.

Answers

Answer:

Well assuming its playing cards

There are 54 playing cards including jokers.

There are only 2 red 6 cards.

The hearts and the diamonds.

Now so techincially its a 2/54 chance

So 2/54 chance of drawing a red card

Answer:

2/52

Step-by-step explanation:

52 cards in a deck as jokers are not used in professional card places   red = 1/2 of 52 = 26/52   drawing red 6   = 1/2 of  4/4   =  2/4      26/52  /  2/52  = 13 which proves 13 cards in each red and 2/52   red 6's in a full deck

[tex]\mathsf{\frac{4}{3} \:\times\frac{1}{2}\: =\: \frac{4}{3} \:\div\frac{2}{1}}[/tex]

Step-by-step explanation:

The mathematical operation of division is the opposite of multiplication. When you divide two fractions, you will have to take the reciprocal of the divisor, and multiply it with the dividend.  

In the given equation, [tex]\mathsf{\frac{4}{3} \:\times\frac{1}{2}\: =\: \frac{4}{3} \:\div\:?}[/tex], we can rewrite this as:  [tex]\mathsf{\frac{4}{3} \:\div\:?\:=\:\frac{4}{3} \:\times\frac{1}{2}}[/tex].

As previously mentioned, division is opposite of multiplication. Since the multiplicand  in the multiplication of two fractions is ½, then we can assume that the divisor (or the missing fraction) must be the reciprocal of ½, which is  [tex]\mathsf{\frac{2}{1}\:or\:2}[/tex].

Therefore, the missing fraction that completes the given mathematical statement is [tex]\mathsf{\frac{2}{1}\:or\:2}[/tex].  

[tex]\mathsf{\frac{4}{3} \:\times\frac{1}{2}\: =\: \frac{4}{3} \:\div\frac{2}{1}}[/tex]

4(x -4)(2x +1)

Step-by-step explanation:

8x² -16 -28x , rearrange it so the exponents will be going form highest to lowest

8x²-28x -16, factor 4

4(2x² -7x -4),

            to get 2x² we need to multiply an x and a 2x

            to get -4 we need to multyply 1 and -4 or -1 and 4 or 2 and -2 (can use       trial and error method here)

4(x -4)(2x +1)

Check

4(x-4)(2x+1) = (4x -16)(2x+1) = 8x² +4x -32x -16 = 8x²-28x -16

So on solving the provided question we can say we can plotting data by x = 0.83; y = 0.79; z = 0.83

Here, we have,

The most typical approach to display data using a chart is a graph that shows the relationship between two additional variables.

Diagrams created by hand or on a computer are also acceptable.

Move 2 units to the right after starting at the origin before going 3 units up.

The coordinates for the points 2, 3, should be shown on the coordinate plane. Clearly state your points.

The pink dot with the letter P thus stands for 2.3.

Before creating a line chart, you need first generate a number line for each value in your data collection.

Put an X (or dot) over each value of the data on the number line after that. For each instance when a value appears in a record, place an X over the corresponding number.

x = 0.83

y = 0.79

z = 0.83

xa = 0.85

ya = 0.85

za = 0.85

Answer:

2, 32

Step-by-step explanation:

The question is asking where X could be (what value it could have) to make it 15 away from W, making a line segment of that length if they were to be connected. This can be solved by individually adding and subtracting 15 to/from the value of W: 17. Adding 15 to 17 gives you 32, while subtracting gives you 2, and X could be either of these, so your answer is 2, 32. (It's common to order them in increasing order, but you shouldn't be marked off if you do it in reverse.)

Trey runs 3 miles in 25 minutes. At the same rate, how many miles would he run in 20 minutes?

Answers

Answer:

Step-by-step explanation:

Set up a proportion.

3/25 = x / 20      Notice that both times are in the denominators. Be sure you always set up a proportion that way. Like units in the denominator. Like units in the numerator.

Cross multiply

3 * 20 = 25 * x                        Combine

60 = 25x                                 Divide by 25

60/25 = x

x = 2.4 miles in 20 minutes.

Answer:

In 20 minutes, Trey would run 2.4 miles.

Step-by-step explanation:

20x = 25

x = 4/5

This means we multiply the number by 0.8

3 * 0.8 =

3/25 = 2.4/20
