Answer:

$10

Step-by-step explanation:

4%  of 500 is 5 dollars  and two years is 10

1. Sample

2. Population

3. Parameter

4. Statistic

Answer:

84 months

Step-by-step explanation:

I × 100 = P × R × T

I = interest = $245

P = principal = $1750

R = rate = 2%

T = time(in years) = ??

245 × 100 = 1750 × 2 × T

24500 = 3500T

24500/3500 = T

7 = T

To convert the time to month:

7 × 12 = 84 months

Answer:

74

Step-by-step explanation:

Both angles x and 106 are supplementary which means

x+106=180

x=180-106

x=74

Answer:

74°

Step-by-step explanation:

In the image you have provided, angle 'x' and 106° are co-interior angles. This mean that both the angles add up to 180°. We can easily identify co-interior angles because the angles would be inside. The other types of angles you can get is vertical and corresponding. Using the information in the second sentence we can set up an equation,

⇒ Form an equation

→ x + 106 = 180

⇒ Minus 106 from both sides to isolate x

→ x = 74°

The values of angle x is 74°

Answer:

19

you divide 266 by 14

Answer:

19

Step-by-step explanation:

266 ÷ 14 = 19

Answer:

62.83 cm squared

Step-by-step explanation:

A = 2πrh+2πr^2

A = 2π(2)(3)+2π(2)^2

A = 2π(6)+2π4

A = 12π+8π

A = 20π

A = 20(3.14)

A = 62.83 cm squared

Answer:

The age of the car in years is the independent variable

The average miles is the dependent variable

Step-by-step explanation:

Typically, the age of the car will have an affect on the number of miles per gallon. However, the number of miles per gallon will not make it gain or lose more years, so the age is independent because it does not depend on another variable.

Hope this makes sense :)

Answer:

1. Geometric sequence

2. 4,096

3. 5,460

Step-by-step explanation:

Part 1

Since the number of letters sent is multiplied by 4 for any subsequent term, the sequence is an example of a geometric sequence as it grows exponentially.

Part 2

Given a geometric sequence, the nth term is determined using the formula:

[tex]T_n=ar^{n-1},$ where r=common ratio, a=first term, n=number of terms[/tex]

In this case,

a=1 (i.e. Nyah)

r=4

Since we want to determine how many letters will be sent on the sixth mailing(i.e after Nyah), n=7

Substituting

[tex]T_6=1*4^{7-1}\\=4^6\\=4096[/tex]

Part 3

To determine how many people would have participated by the sixth mailing, we are required to find the sum of the first seven terms of the geometric sequence.

We use the sum of a geometric sequence formula

[tex]S_n=\dfrac{a(r^n-1)}{r-1} \\S_7=\dfrac{1(4^7-1)}{4-1} \\=\dfrac{16383}{3}\\\\=5461[/tex]

Therefore, excluding Nyah, 5460 people would have participated by the sixth mailing.

Answer:

=4.8875a

Step-by-step explanation:

c(a) = 4.25 a

m(c) = 1.15c

We want to find m(c(a) )= 1.15(4.25a) =4.8875a

Answer:

supplementary angles

Step-by-step explanation:

Supplementary angles add to 180

Complementary angles add to 90

Answer:

187.5 doughnuts (about 188)

62.5 candy bars (about 63)

Step-by-step explanation:

So the proportion of middle schoolers who prefer doughnuts is p = 9/12. That means the proportion of middle schoolers who prefer candy is 1 - 9/12 = 3/12.

The number of middle schoolers is n = 250.

Let X represent the number of doughnuts you need. The expected number is E(X) = np, so multiply them together:

E(X) = np

E(X) = 250 * 9/12 = 187.5 doughnuts

Let Y represent the number of candy bars you need. The expected number is E(Y) = np, so multiply them together:

E(Y) = np

E(Y) = 250 * 3/12 = 62.5 candy bars

Answer:

250/12=20.83

so there is about 21 times more people

20.8333 x 9 = 187.5

250-187.5=62.5

(I am going to put 62 so when you add up it will be 250 instead of 251)

about 188 people will have donuts and about 62 candy bars

Answer:

8 meters

Step-by-step explanation:

8 × 24 = 192, 960 - 192 = 728.

The width of the path will be  8, and the length of the path will be 91, but since the question is just talking about the path's width, then the answer is 8 meters.

Answer:

B

Step-by-step explanation:

The volume of the cone is defined as 

Volume = pi * r^2 * (h/3)

Volume = pi * 1.2^2 * (2.9/3)

Volume = 4.37310 in^3

If the answer is rounded to the nearest tenth of a cubic inch,

then the final answer is letter (B) 4.4 in^3

Answer:

yes

Step-by-step explanation:

Answer: 1) 4:1  2) 60/48

Step-by-step explanation:

1.  12: 3 is the same as 12/3 so you can diving both side by 3.

12:3 ÷ 3/3=4/1

2. 30:24 is the same as 30/24 so you can divide both sides by 6 or multiply both sides by 2.

30/24 * 2/2= 60/48

We just count squares.  Those two half-squares will add to one whole square.  So this is a 3x4 rectangle plus a triangle of area 2.

Answer: 14

Answer:

I believe it is B. n<-5

Step-by-step explanation:

Answer:

n>-5

Step-by-step explanation:

Imagine the< is an equal sign Solve it as you would normally do

3(1-2n) < 33

3(1-2n) = 33

Then use the distributive property

3 - 6n = 33

-3. -3

-6n = 30

Inverse operations

-6n = 30

When you use inverse operations and you divide l

or múltiply by a negative number the signs change around < will change to >

-6n = 30

÷-6. ÷-6

n > -5

Answer:

It's 37

Step-by-step explanation:

The given data set is ;

40,33,37,54,41,34,27,39,35

We arrange the data set in ascending order to obtain;

{27,33,34,35,37,39,40,41,54}

The median is the middle number {37}

Answer:

22

Step-by-step explanation:

Answer:

A

Step-by-step explanation:

To find the mean you have to do the sum of all of the numbers divided by the number of days there are (in this case there are 5: Monday, Tuesday, Wednesday, Thursday, and Friday)

So,

23 + 18 + 24 + 15 + 25 = 105

Then,

105/5 = 21

Answer:

350

Step-by-step explanation:

if you add

22+35+26+17=100

well 100×10=1000

so just multiply 35 by 10= 350
