Answer: I think the answer is B

Step-by-step explanation:

Answer:

The correct option is;

Exactly 3 of the 12 soccer players practiced for at least 75 hours last week,

Step-by-step explanation:

The given information are;

The number of soccer players that practiced = 12 soccer players

The first quartile of the data of the recorded number of hours each soccer player practiced = 75

Therefore, given that that there are 12 soccer players, the number of data points = 12

The value of the 1st quartile is the value of the (n + 1)/4th term

When n = 12, we have;

The 12th quartile = (12 + 1)/4 = 3.25 th term with the values arranged in increasing order;

Therefore, the first quarter has the values for the first 3 players, with the lower practiced hour recorded while the recorded time for the remaining 9 players come after the first quartile;

The correct option is therefore that it must be true that exactly 3 (since we do not represent a player with the remaining fraction of 0.25 in 3.25) of the 12 soccer players practiced for at least 75 hours last week.

Answer:

4x+7 = 5x-20                  

(reason: vertical angles are congruent; property used: distributive)

7 = 1x-20

1x = 7+20

1x = 27

x = 27

Answer:

Step-by-step explanation:

Given

Solving for x

Answer:

x = -6

Step-by-step explanation:

4(1 - x) + 3x = -2(x + 1)

~Distribute both sides

4 - 4x + 3x = -2x - 2

~Combine like terms

4 - x = -2x - 2

~Add x to both sides

4 = -x - 2

~Add 2 to both sides

6 = -x

~Divide -1 to both sides

-6 = x

Best of Luck!

Answer:

the answer is3xy+9-4x. -3x+3xy

Answer:

3xy+9-4x-7+x. -2x+3xy-(x-2)

=3xy+(9-7)+(-4x+x). = -2x+3xy-x+2

=3xy+2-3x. = (-2x-x)+3xy+2

= -3x+3xy+2

Answer:

120

Step-by-step explanation:

Answer:

-20x - 12

Step-by-step explanation:

times -4 by everything inside the bracket

-4 times 5x = -20x

-4 times +3 = -12

-4(5x+3) = -20x - 12

(a positive times a negative is a negative)

Step-by-step explanation: 8 can go into 24 perfectly but not 15 and 5 can go into 15 perfectly but not 24 but 24/3 is 8 and 15/3 is 5

You might say two could do the same thing which is true but we are talking about the GCF, they are asking for the greatest common factor so that's why the answer is 3

Answer:

3

basically,  8 can go into 24 exactly but 15 and 5 can not go into 15 perfectly neither can 24.  24/3 is 8 and 15/3 is 5

You might say two could do the same thing which is true but we are talking about the GCF, they are asking for the greatest common factor so that's why the answer is 3  :D

Answer:

5/72

Step-by-step explanation:

Answer: 24 is the least number of gloves and baseball need to purchase .

Step-by-step explanation:

Given:  Gloves are sold in cases of 8 and baseballs are sold in cases of 12.

To get the  exact same number of gloves as baseballs, the least number of gloves and baseball need to purchase = L.C. M. (8,12)

[L.C.M.= Least common multiple]

Since 8 = 2 x 2 x2

12 = 2 x 2 x 3

So,  L.C. M. (8,12) = 2 x 2 x 2x 3 = 24

Hence, the least number of gloves and baseball need to purchase = 24

Answer:

Step-by-step explanation:

∠A and ∠B are vertical => ∠A=∠B

20x+10=30x-10

20x-30x= -10-10

-10x= -20

x= -20 / -10 = 20 / 10 = 2

x=2

Good luck!

Answer:

2

Step-by-step explanation:

Ok remember this because its going to appear alot in geometry. Vertical angles are ALWAYS congruent and congruent means when two things are equal/ are the same.

If angle a and b are vertical angles what does that mean?

they are CONGRUENT!

you know A = 20x+ 10 and B= 30x-10

so you can write it as

20x+10 = 30x-10

because Angle A and B equal each other

then get the variable by itself so subtract -20x on both sides

10 = 10x-10

then add 10 to both sides which is

20 = 10x

and divide 10 on both side and 20 divided by 10 is 2

so 2 =x

which is the same as x =2  

Answer: Male population = 26,000

               Female population = 24,000

Step-by-step explanation: Male population = X

                                             Female population = Y

               x+y=50,000

               y=50,000-x-(1st equation)

Again (x+x X 5%) + (y+y X 3%) = 52,020

-> x+5x/100 + y+3y/100 = 52020

->  100x+5x+100y+3y =52020

   ________________

                100

-> 105x+103y = 52020-( 2nd Equation)

Putting Eq 1 into 2 ,

105x+103 ( 50,000-x)= 52,020

-> 105x + 5,150,000-103x = 52,020

->2x = 52,020-5,150,000

->2x = 52,000

    x = 26,000 (Male population)

    y = 50,000-26,000

       = 24,000 (Female population)

Answer:

- 72x-1 /8x

Step-by-step explanation:

Answer: -15+1/8x

Step-by-step explanation:

-9+1/4x-6-1/8x

You must add the 9 and 6 because they are both negative numbers and you get -15. You would multiply 1/4 by two in order to subtract 1/4 from 1/8. You would have 2/8-1/8 which would get you 1/8.

Answer: 5489

Step-by-step explanation:

Given the following :

Growth rate (r) = 19% per hour

Sample culture in population = 2300

Size of sample after 5 hours =?

Using the exponential relation:

P = Po * r^t

P = population after 5 hours

Po = Initial sample population

t = time

P = 2300 * (1 +19%)^t

P = 2300 ×(1 + 0.19) ^5

P = 2300 * 1.19^5

P = 2300 * 2.3863536599

P = 5488.61341777

P = 5489 (nearest integer)

Answer:

Step-by-step explanation:

Given the expression [tex]\frac{1}{2} - 1\frac{1}{5}[/tex], we are to find the difference

First convert the mixed fraction [tex]1\frac{1}{5}[/tex] to improper fraction

[tex]1\frac{1}{5}[/tex] = [tex]\frac{6}{5}[/tex]

The expression becomes;

[tex]\frac{1}{2} - \frac{6}{5}[/tex]

Find LCM

[tex]\frac{5-6}{10}[/tex]

Evaluate the resulting expression

[tex]\frac{5-12}{10}\\\\\frac{-7}{10}[/tex]

Hence the correct option is C i.e Negative StartFraction 7 over 10 EndFraction
