Point KK is located at (5,-4)(5,−4) on the coordinate plane. Point KK is reflected over the xx-axis to create point K'K
What ordered pair describes the location of K'?K
Answer:
The ordered pair that describes the location of K' is (5,4).
Step-by-step explanation:
Reflection over the x-axis:
When a point is reflected over the x-axis, it's x-coordinate stays the same, while the signal of the y-coordinate is changed. So
(x,y) -> (x,-y)
In this question:
Point K(5,-4)
Reflection over the x-axis:
(5,-4) -> (5,-(-4)) -> (5,4)
The ordered pair that describes the location of K' is (5,4).

Answer:
B) ∠SBY = 117°
Step-by-step explanation:
interior angles in a pentagon = (5x180) - 360 = 540°
each angle = 540/5 = 108°
interior angles in a octagon = (8x180) - 360 = 1080°
each angle = 1080/8 = 135°
∠SBY = 360 - 108 - 135 = 117°
A group of 20 students attempting a MathematicalChallenge have an average age of 11. When their teacher is included their average age is12. What is the age of the teacher?
Answer:
32.
1st get the total age of the students
x/20 = 11
x=11x20
x =220 (total age of students)
add y ( teachers age) to the equation
(220 + y)/21=12
y= 32
Answer:
32
Step-by-step explanation:
20 * 11= 220
21 * 12= 252
252-220=32

Silas brought an ice chest to the picnic. A model of the ice chest is shown below . 15in Width, 30 inches length, and 15 inches height. What is the volume, in cubic inches of the ice chest?
Answer:
6,750 in.³
Step-by-step explanation:
The ice chest is a rectangular prism or a cuboid.
Volume of the ice chest = volume of rectangular prism = l*w*h
Where,
l = 30 in.
w = 15 in.
h = 15 in.
Volume = 30*15*15 = 6,750 in.³
A rectangular balcony is 10 feet long and 4 feet wide. What is its area?
Olivia has 2 gallons and 3 quarts of vanilla ice cream and 1 gallon and 2 quarts of chocolate ice cream left over from a party What is the total number of gallons and quarts of ice cream that Olivia has left over?
Answer:
4 gallons 1 quart total ice cream
first you add the gallons and the quarts.
so, 2 gallons vanilla + 1 gallon chocolate is 3 gallons.
3 quarts vanilla + 2 quarts chocolate is 5 quarts.
4 of the 5 quarts are taken to make up another gallon.
so the answer is 4 gallons 1 quart total ice cream.

If the bill is divided evenly how much will each person pay? (Round to the nearest cent)
Please show work!
Answer:
$13.20
Step-by-step explanation:
7% = 0.7 so you add that to $32.85 = $33.55
18% of $33.55 is 6.039 so you add that to $33.55 = 39.589
That is the total of the bill so you divide it by 3
39.589 /3 =13.1963
rounded to the nearest cent is $13.20
a company that sells annuities must base the annual payout on the probability distribution of the length of life of the participants in the plan. suppose the probability distribution of the lifetimes of the participants in the plan is approximately normal with mean equal to 66.3 years and standard deviation equal to 3.6 years. nine participants are randomly selected. what is the probability that the average age at death of these nine participants will exceed 68 years
Answer:
0.0778 = 7.78% probability that the average age at death of these nine participants will exceed 68 years
Step-by-step explanation:
To solve this question, we need to understand the normal probability distribution and the central limit theorem.
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
Central Limit Theorem
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
Approximately normal with mean equal to 66.3 years and standard deviation equal to 3.6 years.
This means that [tex]\mu = 66.3, \sigma = 3.6[/tex]
Sample of 9:
This means that [tex]n = 9, s = \frac{3.6}{\sqrt{9}} = 1.2[/tex]
What is the probability that the average age at death of these nine participants will exceed 68 years?
This is 1 subtracted by the pvalue of Z when X = 68. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
By the Central Limit Theorem
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{68 - 66.3}{1.2}[/tex]
[tex]Z = 1.42[/tex]
[tex]Z = 1.42[/tex] has a pvalue of 0.9222
1 - 0.9222 = 0.0778
0.0778 = 7.78% probability that the average age at death of these nine participants will exceed 68 years

plane?
find the area of the triangle
Answer:
Step-by-step explanation:
You know two sides and the angle between them. Use the Law of Cosines to find the third side.
q = √(p²+r²-2pr·cosQ) ≅ 8.533 units
Use Heron's formula to find area
semi-perimeter s = (p+q+r)/2 ≅ 10.317 units
area = √(s(s-p)(s-q)(s-r)) ≅ 16.3 units²

Answer and Step-by-step explanation:
To convert degrees into radians, we multiply by [tex]\frac{\pi }{180}[/tex].
13.
40° × [tex]\frac{\pi }{180}[/tex] = [tex]\frac{2\pi }{9}[/tex]
14.
80° × [tex]\frac{\pi }{180}[/tex] = [tex]\frac{4\pi }{9}[/tex]
15.
100° × [tex]\frac{\pi }{180}[/tex] = [tex]\frac{5\pi }{9}[/tex]
16.
12° × [tex]\frac{\pi }{180}[/tex] = [tex]\frac{\pi }{15}[/tex]
These are the answers.
