Answer:
7
Step-by-step explanation:
the traezoid has congruent legs moving from the top to the bottom
and length is increasing by 2 each for each base, so the bottom base
is 14.

A standard six-sided die was rolled a number of times, and the results were recorded in the table below. Use this information to answer the question. Type your answer into the box as a decimal, rounded to the nearest thousandth.
Side: 1 2 3 4 5 6
Frequency: 42 51 39 52 44 48
What is the probability that an even number was rolled?
Answer:
[tex]P(Even) = 0.547[/tex]
Step-by-step explanation:
Given
[tex]\begin{array}{ccccccc}{Sides} & {1} & {2} & {3} & {4} & {5} & {6} \ \\ {Freq} & {42} & {51} & {39} & {52} & {44} & {48} \ \end{array}[/tex]
Required
P(Even)
The even sides are: 2, 4, 6
So:
[tex]P(Even) = P(2) + P(4) + P(6)[/tex]
This is then calculated as:
[tex]P(Even) = \frac{n(2)}{Total} + \frac{n(4)}{Total} + \frac{n(6)}{Total}[/tex]
Replace n(2), n(4), n(6) with their frequencies
[tex]P(Even) = \frac{51}{Total} + \frac{52}{Total} + \frac{48}{Total}[/tex]
The total frequency is:
[tex]Total =42+51+39+52+44+48[/tex]
[tex]Total =276[/tex]
So:
[tex]P(Even) = \frac{51}{Total} + \frac{52}{Total} + \frac{48}{Total}[/tex]
[tex]P(Even) = \frac{51}{276} + \frac{52}{276} + \frac{48}{276}[/tex]
Take LCM
[tex]P(Even) = \frac{51+52+48}{276}[/tex]
[tex]P(Even) = \frac{151}{276}[/tex]
[tex]P(Even) = 0.547[/tex] --- approximated

Answer:

Step-by-step explanation:
The segments WX and WY are congruent, so ...
5n -2 = 2n +7
3n = 9 . . . . . . . . . . add 2-2n to both sides
n = 3 . . . . . . . . . . . .divide by 3
WY = 2n +7 = 2(3) +7 . . . . substitute for n in the expression for WY
WY = 13
If y=4, what does x equal??
Answer:
since y=4
from one of the equations
6x+4y=46
substitute y=4 In the equation
6x+4(4)=46
6x+16=46
6x=46-16
6x=30
divide both sides by the co efficient of'x'

Answer:
Step-by-step explanation:
x = 2
step-by-step explanation:
if sr parallel to ba then the sides bc and ac are in proportion, that is
\frac{sb}{cs} = \frac{ra}{cr} ← substitute values
\frac{4x+1}{2x} = \frac{13.5}{6} ( cross- multiply )
27x = 6(4x + 1)
27x = 24x + 6 ( subtract 24x from both sides )
3x = 6 ( divide both sides by 3 )
x = 2

please help solving x
Answer:
x = -7
Step-by-step explanation:
m<MLP + m<PLK = m<MLK (angle addition postulate)
(x + 31) + (x + 147) = 164 (substitution)
Solve for x
x + 31 + x + 147 = 164
Add like terms
2x + 178 = 164
2x = 164 - 178
2x = -14
x = -14/2
x = -7
Question: The graph of a second-order polynomial is shown below, and the intercepts with the axes are marked. Explain how you can use the graph to write the polynomial as a product of linear factors (x-a)(x-b). Be sure to state the values of a and b. NEED HELP ASAP
Hello!
Here we are given a second-order polynomial, and the root form of the function.
[tex]y=a(x-c)(x-d)[/tex]
Where c and d are zeros of the function, which is where the graph intersects the x-axis.
[tex]y=a(x+4)(x-3)[/tex]
[tex]-6=a(2+4)(2-3)[/tex]
[tex]-6=-6a[/tex]
[tex]a=1[/tex]
Therefore, the equation of this polynomial would be [tex]y=(x+4)(x-3)[/tex], and the values of a and b would be the x-intercepts.
Hope this helps!

The table shows the number of points scored by a football team in each quarter of the game. Write and simplify an expression to represent how many points the team scored during the entire game.
Expression:
Simplified (combined) expression:
Answer:
Total score → (9p + m - 1)
Step-by-step explanation:
Points scored by the football team in quarter 1 = 3p
Score in quarter 2 = (5p + 2)
Points scored in quarter 3 = (p - 4)
Score of quarter 4 = (m + 1)
Total points scored in entire game = 3p + (5p + 2) + (p - 4) + (m + 1)
= (3p + 5p + p) + m + (2 - 4 + 1)
= 9p + m - 1
Expression representing the total score by the team in entire game will be,
(9p + m - 1)

The radius of a cylindrical construction pipe is 1.5 ft. If the pipe is 17 ft long, what is the volume?
Use the value 3.14 for π and round your answer to the nearest whole number.
Answer:
The volume of the cylinder is 120.10 square feet.
Step-by-step explanation:
Given that the radius of a cylindrical construction pipe is 1.5 ft, to determine its volume if the pipe is 17 ft long, the following calculation must be performed, knowing that the volume of a cylinder arises from multiplying the number pi by the radius at square of the cylinder, and that result by the height of the same:
3.14 x 1.5 ^ 2 x 17 = X
3.14 x 2.25 x 17 = X
7.065 x 17 = X
120.105 = X
Thus, the volume of the cylinder is 120.10 square feet.

What are percentages?A percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate the percent of a number, divide the number by the whole and multiply by 100. Hence, the percentage means, a part per hundred. The word percent means per 100. It is represented by the symbol “%”
Given here Laurie charges her customers a commission fee of 2.5% on the selling price of the house. Let the selling price of the house be x then according to the question we have
2.5% of x = 14,050
x= 14,050 × 100/2.5
= $562000
Hence, the cost of the house is $562000

How much money would you have to invest at 7% compounded semiannually so that the total investment has a value of $2,090 after one year?
Answer:
$1,951.03.
Step-by-step explanation:
To determine how much money would you have to invest at 7% compounded semiannually so that the total investment has a value of $ 2,090 after one year, the following mathematical calculation must be performed:
X x (1 + 0.07 / 2) ^ 1x2 = 2,090
X x 1,035 ^ 2 = 2,090
X x 1.071225 = 2,090
X = 2,090 / 1.071225
X = 1,951.03
Thus, $ 1,951.03 must be invested at 7% per annum compounded semiannually to have $ 2,090 in the account after one year.
