Answer:

5

Step-by-step explanation:

The incenter is the point where all of the angle bisectors meet in the triangle

Using that definition, since point S is the incenter, we know segments RS and SQ are congruent.

1. We can use the Pythagorean Theorem to solve for segment RS first.

a^2+b^2=c^2      or           MR^2+RS^2=MS^2

12^2+b^2=13^2

144+b^2=169

b^2=169-144

b^2=25

b=5                    or                  RS=5

Since segment RS is congruent to segment SQ, SQ=5

Answer:

$142 ; 0.749 ; Normal ; 0.090938

Step-by-step explanation:

Mean and standard deviation :

The mean of the distribution x = $142, because the sample size is sufficiently large, the distribution will be approximately normal (central limit theorem).

Standard deviation of distribution : σ/ sqrt(n)

= 29 / sqrt(1500)

= 0.749

B.)

Shape of sampling distribution of X.

The shape of the sampling distribution will be approximately normal due to the large sample size used. This is according to the central limit theorem whereby distribution of sample converges to normal with increasing sample size. Mean ~ N(142, 0.749²)

C.)

P(X > 143)

Using the relation :

Z = (x - mean) / standard error

Z = 143 - 142) / 0.7489

Z = 1.335

P(Z > 1.335) :

Using the Z probability calculator :

P(Z > 1.335) = 0.090938

Answer:

B

Step-by-step explanation:

Answer:

we conclude that:

Step-by-step explanation:

Given

u = {1,2,3,4,5,6,7,8,9, 10}

X= {1,2,4,6,7,8,9}

Y= {1,2,3,4,7,9)

Z= {2,3,4,7,9)

To determine

X∩Y∩Z = ?

We know that the intersection of three given sets represents the largest set which consists of all the elements that are common to all the sets.

The intersection of sets is denoted by the symbol '∩'.

Thus,

X= {1,2,4,6,7,8,9}

Y= {1,2,3,4,7,9)

Z= {2,3,4,7,9)

X∩Y∩Z = {2, 4, 7, 9}

Therefore, we conclude that:

The slope in the first, second, third, and fourth cases will be 2, -3, 5, and 1, respectively. Then the correct options are A, B, F, and H.

The slope is the ratio of rising or falling and running. The difference between the ordinate is called rise or fall and the difference between the abscissa is called run.

The slope of the line is given as,

m = (y₂ - y₁) / (x₂ - x₁)

The slope in the first case will be given as,

m = (1 + 1) / (1 - 0)

m = 2

Answer:

28 hats

Step-by-step explanation:

We can solve this using a system of equations:

14.95s + 12.95h = 1588.50

s + h = 110

Let's isolate the shirt variable in the second equation:

s + h = 110

s = -h + 110

Now that we have isolated s we can plug it back into the first equation:

14.95(-h + 110) + 12.95h = 1588.50

Solve for h

-14.95h + 1644.5 + 12.95h = 1588.50

-2h + 1644.5 = 1588.50

-2h = -56

h = 28

The football team sold a total of 28 hats.

Hope this helps!!

- Kay :)

The number of hats did they sell should be considered as the 28 hats when the received amount is given.

Since

The football team had a fundraiser .

They received $1588.50 from the sale of 110 shirts and hats .

shirts sold for 14.95 each. hats sold for 12.95 each .

So, the following equations are applied

14.95s + 12.95h = 1588.50

s + h = 110

We can write like

s = -h + 110

Now

14.95(-h + 110) + 12.95h = 1588.50

-14.95h + 1644.5 + 12.95h = 1588.50

-2h + 1644.5 = 1588.50

-2h = -56

h = 28

Hence, The football team sold a total of 28 hats.

Answer:

x = 1

Step-by-step explanation:

( 6^2 + 1 ) 6^x = ( 36 + 1 ) x " multiply by "  6^x = 222

so 37 x 6^x = 222

divide by 37

6^x = 6^1

so

x = 1

The coordinates appear kinda wonky on my screen but are these the correct coordinates? (4,-8) and (-4,2)

What you will need is the mid-point formula.

The midpoint formula is:

(x1 + x2)/2, (y1 + y2)/2

x1 = 4, x2 = -4, y1 = -8, y2 = 2

We just need to plug in the known values and solve

(4 + -4)/2, (-8+2)/2

0/2, -6/2

The answer is (0,-3)

Answer:

680,000

Step-by-step explanation:

Population before growing rate: 400,000

Growing rate: 7%

Duration: 10 years

___

First, you will have to calculate how much does the population increase each year with the said rate, so you will have to multiply the rate by the population to determine that amount.

400,000 x 7/100 = 28,000

So the population increases by 28,000 each year, now you will have to multiply that amount by the amount of years to determine how much the amount of increase.

28,000 x 10 = 280,000

This means that the population has increased by 280,000 in these 10 years. Finally, you will have to add that number to the population amount to get the answer.

400,000 + 280,000 = 680,000

Answer:

a) A = 36π in² ≈ 113.09 in²

b)  $0.98 per slice

c) $0.09 per square inch

Step-by-step explanation:

a) area = πr²

    r= diameter/2 = 12/2 = 6

    A = π(6)²

    A = 36π in² ≈ 113.09 in²

b) s = price per slice

   s = 9.75 ÷ 10

   s = $0.975 ≈ $0.98

c) price per square inch = price ÷ area

   = 9.75 ÷ 113.09

   = $0.086 ≈ $0.09 per square inch

Answer:

Number is 4536

Step-by-step explanation:

Assume;

Same number = a

Multiply of 7 = b

So,

a+a+a+b = 39

3a + b = 39

Use b = 7

3a + b = 39

3a + 7 = 39 (Not possible)

Use b = 14

3a + b = 39

3a + 14 = 39 (Not possible)

Use b = 21

3a + b = 39

3a + 21 = 39

a = 6

So,

Number is 6 x 6 x 6 x 21

Number is 4536

Answer: The first 6 terms are = 8, 10, 12,14,16,18

Step-by-step explanation:

The NTH term of an Arithmetic Sequence is given as

an = a1 + (n - 1 ) d

where a1 = First term  given as 8 and

d=  common difference given as 2

Therefore  We have that

the first term

an = a1 + (n - 1 ) d = 8+(1-1) 2

a1= 8

second term=

an = a1 + (n - 1 ) d= a2= 8 + (2-1) 2

= 8+ 2(1) = 10

3rd term

an = a1 + (n - 1 ) d= a3= 8 + (3-1) 2

= 8+ 2(2)= 8 + 4=12

4th term

an = a1 + (n - 1 ) d= a4= 8 + (4-1) 2

= 8+ 2(3)= 8+6=14

5th term

an = a1 + (n - 1 ) d= a5= 8 + (5-1) 2

= 8+ 2(4)=8+ 8=16

6th term

an = a1 + (n - 1 ) d= a6= 8 + (6-1) 2

= 8+ 2(5)=8 +10 =18
