Answer:

[tex]\frac{5}{2} ; -4[/tex]

Step-by-step explanation:

2x² + 3x - 20 = 0

a = 2 ; b = 3 ; c = -20

[ -b ± √(b² - 4ac) ] /2a = [-3±√(3²-4*2*-20]/2*2

                                 = [-3±√(9+160)]/4

                                = [-3±√169 ]/4

                                = [-3± 13]/4

                                = [tex]\frac{-3+13}{4} ;\frac{-3-13}{4}\\\\=\frac{10}{4} ; \frac{-16}{4}\\\\=\frac{5}{2} , -4[/tex]

2x² + 3x - 20 = 0

2x² + 8x - 5x - 20 = 0

2x(x+4) - 5(x+4) = 0

(x+4)(2x-5) = 0

x+4 = 0

x = -4

2x - 5 = 0

2x = 5

x = 5/2

Answer:

0.6 - 1/4

Convert the decimal to fraction

Thus

0.6 = 3/4

3/5 - 1/4

Find the LCM

the LCM is 20

We get

3/5 - 1/4 = (3(4) - 5)/ 20

= 12-5/20

= 7/20

2/5 + 0.75

0.75 = 3/4

Find the LCM

The LCM is 20

Thus

3/4 +2/5 = ( 3(5) + 2(4))/20

= 15 + 8 /20

= 23 / 20 or 1 3/20

1.75 - 1/6

Convert the decimal to fraction

1.75 = 7/4

Thus we get

7/4 - 1/6

Find the LCM

The LCM is 12

Thus

7/4 - 1/6 = ( 7(3) - 2)/12

= 21 - 2 / 12

= 19/ 12 or 1 7/12

3/10 + 2.125

Convert the decimal to fraction

2.125 = 17/8

Thus

3/10 + 17/8

Find the LCM

the LCM is 40

Thus

3/10 + 17/8 = ( 3(4) + 17(5))/40

= 12 + 85/40

= 97 /40 or 2 17/40

Answer:

A-23,702,805

B- 562,003.722

The standard forms of the given numbers are: Twenty three million seven hundred two thousand eight hundred five can be written as 23,728,805. Five hundred sixty two thousand three and seven hundred twenty two thousandths can be written as 562,003.722. (2 x 1 000 000) + (9 x 10 000) + (1 x 1000) + (4 x 100) + (7 x 0.1) can be written as 2,094,727.

Here is the explanation for each of the answers:

A) Twenty three million seven hundred two thousand eight hundred five can be written as 23,728,805 by grouping the digits into millions, thousands, hundreds, tens, and units.

B) Five hundred sixty two thousand three and seven hundred twenty two thousandths can be written as 562,003.722 by placing the decimal point after the three and then adding two zeros to the right of the decimal point. The thousandths digit is 722, so we need to add two zeros to the right of the decimal point to make sure that the number is accurate to the thousandths place.

C) (2 x 1 000 000) + (9 x 10 000) + (1 x 1000) + (4 x 100) + (7 x 0.1) can be written as 2,094,727 by collecting like terms together. The first term, 2 x 1 000 000, is equal to 2,000,000. The second term, 9 x 10 000, is equal to 90,000. The third term, 1 x 1000, is equal to 1000. The fourth term, 4 x 100, is equal to 400. The fifth term, 7 x 0.1, is equal to 7. Adding all of these terms together, we get 2,094,727.

Answer:

The average speed on this trip was 46.15 mph. The correct option is A.

Step-by-step explanation:

In order to calculate the average speed, we need to apply the following formula:

[tex]v_{avg} = \frac{\text{distance}}{\text{time}}[/tex]

We were given the distance between the two cities in miles, therefore we can directly apply it to the expression. Although the time was given in the hh:mm 12 h format and we need a diference in hours, so we will convert that as shown below:

[tex]\text{time departure} = 9 + \frac{50}{60} = 9.83 \text{ h}[/tex]

[tex]\text{time arrival} = 12 + 5 + \frac{30}{60} = 17.5[/tex]

The elapsed time of the trip is the difference between these:

[tex]\text{time} = 17.5 - 9.83 = 7.67 \text{ h}[/tex]

We can now apply it to the formula:

[tex]v_{avg} = \frac{354}{7.67} = 46.15 \text{ mph}[/tex]

The average speed on this trip was 46.15 mph. The correct option is A.

Answer:

Answer:

( a ) 463 " human resource professionals " believe that the appearance of a job applicant is most important for a good first impression

( b )  Percent wise the confidence interval should be from about 86.6% to 93.4%

Step-by-step explanation:

I believe these first two parts here is sufficient enough to get you started!

" In a Harris poll of 514 human resource professionals, 90% said that the appearance of a job applicant is most important for a good first impression. Part A: Among the 514 human resource professionals who were surveyed, how many of them said that the appearance of a job applicant is most important for a good first impression?

Part B: Construct a 99% confidence interval estimate of the proportion of all human resource professionals believing that the appearance of a job applicant is most important for a good first impression. "

_____

( a ) We are given that n = 514, and p = 90%. The number of human resource professionals that said that the appearance of a job applicant is most important for a good first impression, should be the following -

514 x [tex]\frac{90}{100}[/tex]

= [tex]\frac{46260}{100}[/tex]

= 462.6

As the count of people can't be expressed as a fraction, the solution should be about 463 " human resource professionals. "

_____

( b ) Here the confidence level is 0.99 percent. Knowing that -

1 - ∝ = 0.99,

∝ = 1 - 0.99... = 0.01

Therefore, a 99% confidence interval estimate of the proportion of all human resource professionals believing that the appearance of a job applicant is most important for a good first impression should be calculated as directed in the attachment. By that the interval ranges as such -

0.8659 < p < 0.9341

And percent wise the confidence interval should be from about 86.6% to 93.4%

No.  She only estimated instead of hovering over the intersection to find the exact point.

Step-by-step explanation:

I used a graphing tool to graph the two lines. They pass at (6.25, -6.25). Since Keisha said the solution was (6, -6), which is not correct, she has most likely rounded the two values instead of finding the exact one.

Answer:

1/2

Step-by-step explanation:

If the locker has 3 non zero digits, this means the digits will take values from 1 to 9. If the first digits is 3, the remaining digits can take any of the values in the set {1, 2, 4, 5, 6 7, 8, 9}

Total elements in the set = 8

Total odd numbers there = {1, 5, 7, 9} = 4 odd numbers

If the next digit is odd, probability that the next digit is odd will be Total odd numbers/Total elements in the set = 4/8 = 1/2

Answer:

Step-by-step explanation:

hello

a) Pop as this is the one with the most CDs

b) 30 as this is a full one 20 + half 10 = 30

c) POP  5*20= 100

Jazz 2*20=40

Classical 1.5*20=30

Rock 3*20=60

so the total is 100+40+30+60 = 230

hope this helps

Answer:

a) The Pop CD is the mode (as it has higest sold )

b) no. of rock CDs sold = 20 × 3 = 60

  no. of classical CDs sold = 20+ 10 = 30

∴The no of Rock CDS more than Classical CDs = 60 - 30 = 30

c)  Pop CDs = 20 × 5 = 100

   JazzCDs = 20 ×2 = 40

   Classical CDs = 20 + 10 = 30

   Rock CDs = 20 × 3 = 60

∴ Total no.of CDs sold =  100 + 40 + 30 + 60 = 230

Answer:

a. Let's call the first number x which would make the other 2 numbers x + 2 and x + 4. Since they have a sum of 54 we can write:

x + x + 2 + x + 4 = 54

3x + 6 = 54

3x = 48

x = 16 so the numbers are 16, 18, 20.

d. We can write:

30 + x = 4(3 + x)

30 + x = 12 + 4x

18 = 3x

x = 6 years

Answer:

x = 1 1/4

Step-by-step explanation:

sqrt( 7x+2) = sqrt(3x+7)

Square each side

(sqrt( 7x+2))^2 = (sqrt(3x+7))^2

7x+2 = 3x+7

Subtract 3x from each side

7x-3x +2 = 3x+7-3x

4x+2 = 7

Subtract 2 from each side

4x+2-2 = 7-2

4x = 5

Divide by 4

4x/4 = 5/4

x = 1 1/4

Check for extraneous solution

sqrt( 7*5/4+2) = sqrt(3*5/4+7)

sqrt( 35/4 + 8/4) = sqrt(15/4+28/4)

sqrt( 43/4) = sqrt(43/4)

Solution is valid

Answer:

25 sweets.

Step-by-step explanation:

If you have 56 sweets and you give 2/7 to Adam, you will have 5/7 of the sweets left. 56 * (5 / 7) = 8 * 5 = 40. So, you have 40 sweets left from giving 2/7 away to Adam.

If you eat 3/8 of the 40 sweets, you will have 5/8 of the 40 left. 40 * (5/8) = 5 * 5 = 25. You will have 25 sweets left; yum!

Hope this helps!

Answer:

19 sweets left

Step-by-step explanation:

Add the fractional amount of how many you gave to Adam and the fractional amount of how many you ate.

2/7 + 3/8

16/56 + 21/56

37/56

You used/gave 37 sweets out of 56.

56 - 37 = 19

Step-by-step explanation:

The statement “The supplement of an acute angle is an obtuse angle.” is always true because the sum of any two supplementary angles is 180°, so if one of them less than 90° (acute), then the other must be greater than 90° (obtuse)

Answer:

The statement is always true because the sum of the two angles must be 180 degrees to be supplementary. If the first angle is an acute angle, then it has a measure of less than 90 degrees. To sum 180 degrees, the second angle would need to be more than 90 degrees, making it an obtuse angle.

Answer:

5

Step-by-step explanation:

LM + MN = LN

4+5x = 9x

Subtract 5x from each side

4+5x-5x = 9x-5x

4 = 4x

Divide by 4

4/4 = 4x/4

1 =x

We want MN

5x =5*1 = 5

MN =5

Answer:

the length of MN is 5(1), or 5

Step-by-step explanation:

Segments add up to 9x here:  4 + 5x = 9x, so 4 = 4x and x must therefore be 1.

Then the length of MN is 5(1), or 5, and the length of LN is 9(1) = 9.
