There is a pair of parallel sides in the following shape.
9. 5. 3

Answer:

Christine has $18, Kareem has $23, and Trey has $92.

Step-by-step explanation:

This can be solved by using variables to represent the unkown values.

x = Christine's money

x + 5 = Kareem's money.

4(x + 5) = Trey's money.

x + (x + 5) + 4(x + 5) = 133

2x + 5 + 4x + 20 = 133

6x = 108

x = $18

This means that Christine has $18, Kareem has $23, and Trey has $92.

Hope this helps

Answer:

10 + 7 + 4 + . . .; n = 5​

The series is arithmetic

Common difference between terms = (-3)

10 - 3 = 7

7 - 3 = 4

Or:

10 + (-3) = 7

7 + (-3) = 4

--------------------------------------------------------------------------

Another example:

Arithmetic:

5, 9, 13, 17

common difference = 4

5 + 4 = 9

9 + 4 = 13

Geometric:

4, 8, 16, 32

4 × 2 = 8

8 × 2 = 16

16 × 2 = 32

common ratio = 2

--------------------------------------------------------------------------

10 + 7 + 4 + . . .; n = 5​

a₁ = 10

a₂ = 7

a₄ = a₃ + d = 4 + (-3) = 4 - 3 = 1     (d = common difference)

a₅ = a₄ - 3 = 1 - 3 = -2

Or with formula:

[tex]d=a_{n} -a_{n-1}[/tex]

d = a₂ - a₁ = 7 - 10 = -3

aₙ = a₁ + (n - 1)d

fourth term = a₄ = 10 + (4 - 1)(-3) = 10 + 3(-3) = 10 + (-9) = 10 - 9 = 1

fifth term = a₅ = 10 + (5 - 1)(-3) = 10 + 4(-3) = 10 + (-12) = 10 - 12 = -2

Sum of the finite series (if n = 5):

[tex]S_{n} =\frac{n(a_{1} +a_{n} )}{2} \\S_{5} =\frac{5(a_{1} +a_{5} )}{2} \\S_{5} =\frac{5(10 +(-2) )}{2} \\S_{5} =\frac{5(8 )}{2} =\frac{40}{2} =20[/tex]

~pinetreee

The mean absolute deviation for the data set is 51.5.

The mean is the average value which can be calculated by dividing the sum of observations by the number of observations

Mean = Sum of observations/the number of observations

Median represents the middle value of the given data when arranged in a particular order.

We are given that;

Mean= 59

{419,450,462,499,520,521,589,612}

Now,

Count the number of data values in the set. In this case, n = 8.

Subtract the mean from each data value and take the absolute value. For example:

∣419−509∣=90

∣450−509∣=59

∣462−509∣=47

∣499−509∣=10

∣520−509∣=11

∣521−509∣=12

∣589−509∣=80

∣612−509∣=103

Add up all the absolute differences and divide by n. For example:

MAD=890+59+47+10+11+12+80+103​

MAD=412​/8

MAD=51.5

Therefore, by mean the answer will be 51.5.

The total number of student tickets were sold is 183 if the theater production cost $18 for students and $25 for non-students.

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

Let's suppose the x number of students tickets were sold and

y number of tickets were sold for non students.

Then we can frame two linear equations:

x + y = 320 ...(1)

18x + 25y = 6719 ...(2)

From equation (1) take the value of y and plug into the equation (2)

18x + 25(320 - x) = 6719

18x + 8000 - 25x = 6719

7x = 1281

x = 183 tickets

Thus, the total number of student tickets were sold is 183 if the theater production cost $18 for students and $25 for non-students.

Answer:

12^2x = 7^4 = 2401

7^2=12^x

We know that a^x * a^x = a^(x+x) or a^2x

Multiply each side by 12^x

7^2 * 12^x=12^x * 12^x

7^2 * 12^x = 12^(x+x)

Replace 12^x with 7^2 on the left hand side since they are equal

7^2 * 7^2 = 12^ (2x)

7^(2+2) = 12^(2x)

7^4 = 12^2x

  ∠B = 40°

Step-by-step explanation:

The given angle relations can be expressed in two equations.

__

  A + B = 90° . . . . . . . . angles are complementary

  A×(1 -20%) = B . . . . . B is 20% smaller

__

Using the second equation to substitute for B in the first equation, we get ...

  A + 0.80A = 90° . . . . . . substitute for B

  A = 90°/1.8 = 50° . . . . . collect terms, divide by the coefficient of A

  B = A(0.80) = 40° . . . . find B from A

The measure of angle B is 40°.

The questions are all illustrations of conditional probabilities, and they can be solved using the general conditional probability formula; P(A|B) = P(A and B)/P(B)

The conditional probability P(A|B) is calculated using:

P(A|B) = P(A and B)/P(B)

Using the above formula, we have:

P(has at least 4 sides| not a hexagon) = 38/50

P(has at least 4 sides| not a hexagon) = 0.76

P(not a square | has less than 7 sides) = 30/45

P(not a square | has less than 7 sides) = 0.67

P(not an octagon | not a triangle) = 39/51

P(not an octagon | not a triangle) = 0.76

P(octagon | sum of interior angle measures is at least 600) = 9/25

P(octagon | sum of interior angle measures is at least 600) = 0.36

The conditional probability is calculated using:

P = P(perfect attendance and honor roll)/P(Honor roll)

So, we have:

P = 25%/38%

Evaluate

P = 0.66

Hence, the probability that a student has a perfect attendance, given that he made the honor roll is 0.66

The conditional probability is calculated using:

P = P(Home has a pool and at least 3 bedrooms)/P(at least 3 bedrooms)

So, we have:

P = 25%/70%

Evaluate

P = 0.36

Hence, the probability that a home has a pool, given that it has at least 3 bedrooms is 0.36

Using the conditional probability formula in (a), we have:

P(uses Ins tag ram| does not use Sna pch at) = 45/(20 + 45)

P(uses Ins tag ram| does not use Sna pch at) = 0.69

P(does not use Ins tag ram| uses Sna pch at) = 25/(30 + 25)

P(uses Instag ram| does not use Sna pch at) = 0.45

Using the conditional probability formula in (a), we have:

P(plays sport| has a part-time job) = 22/68

P(plays sport| has a part-time job) = 0.32

P(has a part-time job| plays sport) = 22/40

P(has a part-time job| plays sport) = 0.55
