Jalen says that 60% of his teammates are over 70 inches. Is Jalen's statement correct? 73, 61, 62, 59, 75, 60, 74, 75, 78, 69, 70

A. No, because there are 5 players with a height greater than 70 inches and that's about 45% of the players B. Yes, there are at least 9 players with a height of at least 70 inches and that is 60% of the players C. No, there is one player with a height of 70 inches and that is 9% of his teammates. D. Yes, because the median height of the ponies is 60 and 60% of the ponies would be taller​

Answer:

y = 4

Step-by-step explanation:

distribute

10 + 2y = 18

minus 10 from both sides

2y = 8

divide by 2

y = 4

Answer: y=4

Step-by-step explanation:

2(5+y)=18

youre going to start by distributing the 2 to (5+y)

10+2y=18

then subract 10 from 18

2y=8

and then divide 2 on both sides

y=4

Step-by-step explanation:

Tr+1 = nCr * a^(n-r) * b^r.

Therefore the coefficients of the binomial expansion of (p + q)⁶ are 6C0, 6C1, 6C2, 6C3, 6C4, 6C5 and 6C6.

=> 1, 6, 15, 20, 15, 6, 1.

You can also look up Pascal's triangle which gives shortcuts in finding the coefficients for binomial expansions.

Answer:

Answer:

NO

Step-by-step explanation:

The answer is no because the first column is 1 times 1 which is 1. The second column is 2 times 1 which is not 4. So this table is not proportional.

Step-by-step explanation:

7 [tex]\frac{1}{2}[/tex] ÷ 2

A. 2 × ? = 7[tex]\frac{1}{2}[/tex]

   Divide 2 on both sides to bring all the constants on one side...

   ? = 7 1/2 ÷ 2

B. 7 1/2 x ? = 2

  Divide 7 1/2 on both sides to isolate the ?

  ? = 2 ÷ 7 1/2

C. 2 x 7 1/2

    You already know that the initial problem is asking for an answer that is half of 7 1/2 not twice 7 1/2

D. ? x 7 1/2 = 2

   Divide 7 1/2 on both sides

    ? = 2÷ 7 1/2

E. It's basically the same thing as A

Answer:

100 cm²

Step-by-step explanation:

In a square

length of the sides (L) = 10 cm

Area of square (A) = L² = ( 10 ) ² = 100 cm²

Answer:

100cm^2

Step-by-step explanation:

10×10 is 100

so it's 100cm squared

Answer:

x squared over 4 plus y squared over 8 equals 1

Step-by-step explanation:

The general equation of ellipse is given as;

(x²/a²) + (y²/b²) = 1

The coordinates of a foci are: (±c, 0) where;

c² = b² - a²

However, we know that equation of directrix is; x = ±a/e

Now, Directrix is given ±4

Thus, a/e = 4

a = 4e

We also know that c = ae from ellipse foci coordinates.

Thus, ae = 2

since ae = 2, then (4e)e = 2

4e² = 2

e² = 2/4

e = 1/2

Thus;

a = 4 × 1/2

a = 2

Since c² = b² - a²;

2² = b² - 2²

4 = b² - 4

b² = 8

From (x²/a²) + (y²/b²) = 1, we can put our values to get;

x²/4 + y²/8 = 1

Answer:

[tex]Probability = \frac{1}{792}[/tex]

Step-by-step explanation:

Given

[tex]Questions = 12[/tex]

[tex]Selection = 5[/tex]

Required

Probability of grading the selected 5 by Andrew

First, we need to determine the total number of selections.

This is calculated as: [tex]^{12}C_{5}[/tex]

Solving further:

[tex]^{12}C_{5} = \frac{12!}{(12-5)!5!}[/tex]

[tex]^{12}C_{5} = \frac{12!}{7!5!}[/tex]

[tex]^{12}C_{5} = \frac{12*11*10*9*8*7!}{7!*5*4*3*2*1}[/tex]

[tex]^{12}C_{5} = \frac{12*11*10*9*8}{5*4*3*2*1}[/tex]

[tex]^{12}C_{5} = \frac{95040}{120}[/tex]

[tex]^{12}C_{5} =792[/tex]

There is only 1 for Andrew's question selection.

So, the required probability is:

[tex]Probability = \frac{1}{792}[/tex]

Answer:

3x-x+2=4

Step-by-step explanation:

Children = x

Adults = y

x + y = 754...1

1.50x + 2.25y = 1422...2

Multiply (1) by 2.25

2.25x + 2.25y = 1696.50...3

1.50x + 2.25y = 1422...2

Subtract (2) from (3)

0.75x = 274.50

x = 366

Substitute x = 366 in (1)

x + y = 754

366 + y = 754

y = 388

366 children and 388 adults swam at the pool.

Answer:

6 hours

Step-by-step explanation:

she played game 25% of the time.

25% of 30 hours is 7.5 hours

she researched 5% of the time.

5% of 30 hours is 1.5 hours

so she played game 7.5-1.5=6 more hours than she researched

Answer: ↓↓↓Btw sorry its not in order

Step-by-step explanation:

m∠62 and ∠g are vertical angles so they're congruent.

∠g = 62°

∠f and m∠62 are linear pairs so they're supplementary

∠f + 62 = 180

∠f = 118°

∠e is a right angle and is supplementary to a 90° angle

∠e = 90°

Adding ∠e, m∠28° and the missing angle should sum up to 180° since its a triangle. x = missing angle

x + ∠e + m∠28 = 180°

x + 90 + 28 = 180

x + 118 = 180

x = 62°

∠h ≅ x

∠h ≅ 62

∠h = 62°

∠b and m∠28 are vertical angles so they're congruent.

∠b ≅ m∠28

∠b = 28°

∠b and ∠a are linear pairs so they are supplementary.

∠a + ∠b = 180

∠a + 28 = 180

∠a = 152°

∠c and ∠a are corresponding angles so they're congruent.

∠c ≅ ∠a

∠c ≅ 152

∠c = 152°

∠c and ∠j are vertical angles so they're congruent.

∠j ≅ ∠c

∠j ≅ 152

∠j = 152°

The corresponding angle of c is 152° as well. Let's call it y. Y corresponds to the angle with a bisector. Call that whole angle z.

z ≅ y

z ≅ 152

z = 152°

Z has a bisector meaning the two angles that formed because of the bisector are congruent.

∠d and the other angle add up to 152°. They're equal.

∠d = 152 ÷ 2

∠d = 76°

Hope I helped!

Answer:

Polly has 10 yo-yos.

Step-by-step explanation:

Since Eureka has 20 yo-yos, and has twice as many yo-yos as Polly, to determine the number of yo-yos that Polly has it is necessary to perform the following equation:

Polly's Yo-yos = X

Eureka's Yo-yos = 2X

20 = 2X

20/2 = X

10 = X

Therefore, Polly has 10 Yo-yos, half the number Eureka has.

9514 1404 393

Answer:

  C

Step-by-step explanation:

Corresponding angles are listed in the same order in the mapping statement.

C' is the third vertex named in A'B'C'D'. It corresponds to the third vertex named in ABCD, which is C.

  angle C' corresponds to angle C

Answer:

B would be the answer.

Step-by-step explanation:

Use what they said. All angles in a triangle would sum to 180 degrees.

So based on that, 107 + 33 + <x = 180

140 + <x = 180

<x would then be 40 degrees

Answer:

4!

Step-by-step explanation:

40 x 4 = 160

160+ 140 = 300

Answer:

4 dresses

Step-by-step explanation:

If she starts with $300 and ends up with $140, that means that she spent $160. So, since each dress costs $40, you divided $160 by $40, which equals 4. So Michelle bought 4 dresses.

Answer:

12/ x^2+7x

Step-by-step explanation: Took the test and got it right

The product of the expression 3/(x+7) and 4/x is equivalent to the expression 12/(x^2+7x) option 12/(x^2+7x) is correct.

Polynomial is the combination of variables and constants in a systematic manner with "n" number of power in ascending or descending order.

The polynomial can be represented as:

[tex]\rm a_1x+a_2x^2+a_3x^3+a_4x^4..........a_nx^n[/tex]

We have polynomial:

[tex]\rm = \frac{3}{x+7}\times \frac{4}{x}[/tex]

[tex]=\rm \frac{3\times4}{x(x+7)}[/tex]

[tex]\rm = \frac{12}{x^2+7x}[/tex]

Thus, the product of the expression 3/(x+7) and 4/x is equivalent to the expression 12/(x^2+7x) option 12/(x^2+7x) is correct.
