Answer:
18in.,2ft.,1yd.,2yd.,9ft.
Step-by-step explanation:
18 inches is 1 foot and 6 inches so its the smallest. 2 feet is smaller than a yard so it goes next.After that is the yard it is 3 feet so thats why it goes after 2 feet.2 yards is 6 feet and 9 feet is bigger than 6 so thats why its the last.

A simple random sample of electronic components wil be selected to test for the mean lifetime in hours. Assume that component lifetimes are normally distributed with population standard deviation of 16 hours. How many components must be sampled so that a 99% confidence interval will have margin of error of 3 hours
Answer:
189 components must be sampled.
Step-by-step explanation:
We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:
[tex]\alpha = \frac{1 - 0.99}{2} = 0.005[/tex]
Now, we have to find z in the Ztable as such z has a pvalue of [tex]1 - \alpha[/tex].
That is z with a pvalue of [tex]1 - 0.005 = 0.995[/tex], so Z = 2.575.
Now, find the margin of error M as such
[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]
Assume that component lifetimes are normally distributed with population standard deviation of 16 hours.
This means that [tex]\sigma = 16[/tex]
How many components must be sampled so that a 99% confidence interval will have margin of error of 3 hours?
n components must be sampled.
n is found when M = 3. So
[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]
[tex]3 = 2.575\frac{16}{\sqrt{n}}[/tex]
[tex]3\sqrt{n} = 2.575*16[/tex]
[tex]\sqrt{n} = \frac{2.575*16}{3}[/tex]
[tex](\sqrt{n})^2 = (\frac{2.575*16}{3})^2[/tex]
[tex]n = 188.6[/tex]
Rounding up:
189 components must be sampled.
What is the perimeter of parallelogram RSTU, rounded to the nearest whole number?
Given:
The vertices of the parallelogram RSTU are R(-4,4), S(2,6), T(6,2) and U(0,0).
To find:
The perimeter of parallelogram RSTU, rounded to the nearest whole number.
Solution:
Distance formula:
[tex]D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Using the distance formula, we get
[tex]RS=\sqrt{(2-(-4))^2+(6-4)^2}[/tex]
[tex]RS=\sqrt{(6)^2+(2)^2}[/tex]
[tex]RS=\sqrt{36+4}[/tex]
[tex]RS=\sqrt{40}[/tex]
[tex]RS=6.32[/tex]
Similarly,
[tex]ST=\sqrt{\left(6-2\right)^2+\left(2-6\right)^2}[/tex]
[tex]ST\approx 5.66[/tex]
[tex]TU=\sqrt{\left(0-6\right)^2+\left(0-2\right)^2}[/tex]
[tex]TU\approx 6.32[/tex]
[tex]RU=\sqrt{\left(0-\left(-4\right)\right)^2+\left(0-4\right)^2}[/tex]
[tex]RU\approx 5.66[/tex]
Now, the perimeter of the parabola is:
[tex]P=RS+ST+TU+RU[/tex]
[tex]P=6.32+5.66+6.32+5.66[/tex]
[tex]P=23.96[/tex]
[tex]P\approx 24[/tex]
The perimeter of the parallelogram RSTU is 24 units.
Therefore, the correct option is C.
Note: Unit of perimeter cannot be in square.

Winston typically spends about $200 per year playing the lottery. If he took that same
amount of money, for 30 years, and invested it in an index fund earning an average of
6%, approximately how much money would Winston have?
A. More than $12,000, because the investment will grow faster over time as the interest
compounds.
B. Less than $6000, because inflation would make his money less valuable.
C. Exactly $6000.
D. Approximately $6360, because he earns almost $400 in interest.
Answer:
point!!!!!!!
Step-by-step explanation:
Winston would have A. More than $12,000, because the investment will grow faster over time as the interest compounds.
If Winston invested $200 every year at 6% for 30 years, the $200 would be an annuity and the future value of an Annuity is calculated as:
= Annuity x ( (1 + rate) ^ number of years - 1) / rate
= 200 x ( ( 1 + 6%) ³⁰ - 1) / 6%
= $15,811.64
Winston would have $15,811.64 which is more than $12,000 because compounded interest makes investments grow faster.

For [tex]x=\frac{1}{12}[/tex]
[tex]f(\frac{1}{12})=\frac{1}{3(\frac{1}{12})}[/tex]
[tex]=\frac{1}{\frac{1}{4}}[/tex]
[tex]=1\times\frac{4}{1}[/tex]
[tex]=4[/tex]
[tex]g(x)=\frac{1}{x^2}[/tex]
For [tex]x=\frac{1}{5}[/tex],
[tex]g(\frac{1}{5})=\frac{1}{(\frac{1}{5})^2}[/tex]
[tex]=\frac{1}{\frac{1}{25}}[/tex]
[tex]=25[/tex]
[tex]f(\frac{1}{12})-g(\frac{1}{5})=4-25[/tex]
[tex]=-21[/tex]
5). f(x) = -2x² + 3x - 8
f(k + 4) = -2(k + 4)² + 3(k + 4) - 8
= -2(k² + 8k + 16) + 3(k + 4) - 8
= -2k² - 16k - 32 + 3k + 12 - 8
= -2k² - 13k - 28

3/4 + ((1/3)/(1/6)) -(-1/2)
= 3/4 + ((2/6)/(1/6)) + 2/4

Q) 3/4 + {(1/3) ÷ (1/6)} - ( - 1/2) = ?
→ 3/4 + {(1/3) ÷ (1/6)} - ( - 1/2)
→ 3/4 + {(1/3) × (6/1)} - ( - 1/2)
→ 3/4 + 6/3 - ( - 1/2)
→ {(3/4) + (6/3)} + 1/2

What is the P(A and B) given that P(A) = 0.53, P(B) = 0.39, and P(A or B) = 0.48
Answer:
P(A and B) = 0.44
Step-by-step explanation:
Venn probabilities:
Suppose that we have two events, A and B. The probability of A and B is:
[tex]P(A \cap B) = P(A) + P(B) - P(A \cup B)[/tex]
In which [tex]P(A \cup B)[/tex] is P(A or B).
In this question:
[tex]P(A) = 0.53, P(B) = 0.39, P(A \cup B) = 0.48[/tex]
Then
[tex]P(A \cap B) = P(A) + P(B) - P(A \cup B) = 0.53 + 0.39 - 0.48 = 0.44[/tex]
So
P(A and B) = 0.44

please help!
The transformation of a function may involve any change. The correct option is D.
How does the transformation of a function happen?The transformation of a function may involve any change.
Usually, these can be shifted horizontally (by transforming inputs) or vertically (by transforming output), stretched (multiplying outputs or inputs) etc.
If the original function is y = f(x), assuming horizontal axis is input axis and vertical is for outputs, then:
Horizontal shift (also called phase shift):
Left shift by c units: y=f(x+c) (same output, but c units earlier)Right shift by c units: y=f(x-c)(same output, but c units late)Vertical shift:
Up by d units: y = f(x) + d Down by d units: y = f(x) - dStretching:
Vertical stretch by a factor k: y = k \times f(x)Horizontal stretch by a factor k: y = f\left(\dfrac{x}{k}\right)The given function f(x)=x² is transformed to h(x)=(1/8)x^2-13, therefore, the graph or f(x) is horizontally stretched by a factor of 8 and shifted 13 units to the right.
Hence, the correct option is D.

Answer:
C. (-1, 2) and (4, 7)
Step-by-step explanation:
It may be simplest just to try the answer choices.
We notice that y = x+3 is not satisfied by the points in choices A or D, so those can be eliminated.
__
The second equation can be written in vertex form as ...
y = (x -1)^2 -2
This equation is not satisfied by the points of choice B.
Using (-1, 4) (from choice B), we get 4 = (-1-1)^2 -2 = 4-2 = 2 . . . FALSE.
However it is a good match for the points of choice C.
Using (-1, 2) (from choice C), we get 2 = (-1-1)^2 -2 = 4 -2 = 2 . . . True
The appropriate choice is ...
(-1, 2) and (4, 7)
Miguel draws a square on a coordinate plane. One vertex is located at (5,4). The length of each side is 3 units. Circle the letter by all the ordered pairs that could be another vertex. A. (5,1) B. (5,7) C. (7,8) D. (2,6) E. (2,1)
I will give brainliest if you answer both questions!
Answer:
A, B, and E.
Step-by-step explanation:
We know that one vertex is at (5, 4), and each side of our square is 3 units long.
Then the distance between the known vertex and another vertex is 3 units (if those vertexes are connected by a side of the square) or (√2)*3 units (if those vertexes are connected by the diagonal of the square).
Also remember that the distance between two points (a, b) and (b, c) is:
distance = √( (a - c)^2 + (b - d)^2)
So we need to find the distance between our point and all the ones given in the options:
A) the distance between (5, 4) and (5, 1) is:
distance = √( (5 - 5)^2 + (4 - 1)^2) = 3
Then point (5, 1) can be a vertex.
B) The distance between (5, 4) and (5, 7) is:
distance = √( (5 - 5)^2 + (4 - 7)^2) = 3
Then (5, 7) can be a vertex.
C) The distance between (5, 4) and (7, 8) is:
distance = √( (5 - 7)^2 + (4 - 8)^2) = √( 2^2 + 4^2) = √20
Point (7, 8) can not be a vertex.
D) The distance between (5, 4) and (2, 6) is:
distance = √( (5 - 2)^2 + (4 - 6)^2) = √( 3^2 + 2^2) = √13
Point (2, 6) can not be a vertex.
E) The distance between (5, 4) and (2, 1) is:
distance = √( (5 - 2)^2 + (4 - 1)^2) = √( 3^2 + 3^2) = √18 = √(2*9) = √2*√9 = √2*3
Then point (2, 1) can be a vertex.
