Answer:
Large number from two numbers = 1,440
Step-by-step explanation:
Given:
Ratio of two numbers = 9 : 2
Smaller number from two numbers = 320
Find:
Large number from two numbers
Computation:
Large number from two numbers / Smaller number from two numbers = Ratio of two numbers
Large number from two numbers / 320 = 9 / 2
Large number from two numbers = 2,880 / 2
Large number from two numbers = 1,440

The area of a greeting card is 25.62 square inches. If the length of the card is 6.1
inches, find its width.
Answer:
width = 4.2 inches
Step-by-step explanation:
Area rectangle = wl
l= 6.1 inches
w= ?
6.1 * w = 25.62
Divide both sides by 6.1
w= 4.2
6.1 x 4.2 = 25.62 square inches
If the surface area of a cube is 150 cm2, what is the volume of the cube
Answer:
V = 125 in^3
Step-by-step explanation:
A cube has 6 sides, and the area of each is equal to the side length squared:
A = 6x^2
A is given as 150 cm^2, and so is equal to 6x^2. Thus, x = the side length = 5 cm.
The volume of the same cube is given by V = x^3, which here is 5^3 in^3, or V = 125 in^3
You want to be able to withdraw $25,000 each year for 20 years. Your account earns 5% interest.
a. How much do you need in your account at the beginning? Do not include units!
b. How much total money will you pull out of the account? Do not include units!
C. How much of that money is interest? Do not include units!
Answer:
a. $311,555.26
b. $500,000
c. $188,444.74
Step-by-step explanation:
The computation is shown below:
a. Here we have to determine the present value
Given that
PMT = $25,000
NPER = 20
RATE = 5%
FV = $0
The formula is shown below:
= -PV(RATE;NPER;PMT;FV;TYPE)
after applying the above formula, the amount that need in the beginning is $311,555.26
b. The total money should be
= $25,000 × 20 years
= $500,000
c. The amount of interest is
= $500,000 - $311,555.26
= $188,444.74

Find the measure of Arc PQ
The measure of arc PQ is 120°
What is circle geometry?A circle is a special kind of ellipse in which the eccentricity is zero and the two foci are coincident.
There is a theorem in circle geometry that states that angle formed by an arc is twice the angle formed at the circumference.
arc RQ = 2 × 50
= 100°
Also, the total angle on the circumference of a circle is 360°. Circumference is the outer part of a circle.
Therefore;
arc RP + arc RQ + arc PQ = 360°
140 +100 + x = 360°
x = 360 -240
x = 120°
Therefore the value of arc PQ is 120°

A cylindrical jar of jam has a diameter of 6cm and a height of 8cm if the jar is 70% full how many cubic centimeters of jam is in the jar?
Answer:
[tex] 158.256 \: {cm}^{3} [/tex]
Step-by-step explanation:
For cylindrical jar:
Diameter = 6 cm
Radius (r) = 6/2 = 3 cm
Height (h) = 8 cm
[tex]V_{cylindrical \: jar} = \pi {r}^{2} h \\ \\ = 3.14 \times {(3)}^{2} \times 8 \\ \\ = 3.14 \times 72 \\ \\ = 226.08 \: {cm}^{3} \\ \\ \because \: jar \: is \: filled \: upto \: 70 \% \\ \\ \therefore \: V_{jam} = 70 \% \: of \: V_{cylindrical \: jar} \\ \\ \therefore V_{jam} = 0.70 \times 226.08 \\ \\ \therefore V_{jam} = 158.256 \: {cm}^{3} [/tex]

Account II:
The balance in the account after 2 years will be ...
A = P(1 +r)^t
A = $3000(1 +0.04)^2 = $3244.80

a total of 12,650 voters completed an online survey that asked if they are going to vote for a certain political canidate in an upcoming
election. how many said they are not going to vote for the candidate
Answer:You have roughly the same chance of being called as anyone else living in the United States who has a telephone. This chance, however, is only about 1 in 154,000 for a typical Pew Research Center survey. To obtain that rough estimate, we divide the current adult population of the U.S. (about 235 million) by the typical sample size of our polls (usually around 1,500 people). Telephone numbers for Pew Research Center polls are generated through a process that attempts to give every household in the population a known chance of being included. Of course, if you don’t have a telephone at all (about 2% of households), then you have no chance of being included in our telephone surveys.

Part 1 of 2
(a) How large a sample must be drawn so that a 99.9% confidence interval for u will have a margin of error equal to 4.1? Round the answer up to the nearest integer. (Round the critical value to no less than three decimal places.) A sample size of is needed to be drawn in order to obtain a 99.9% confidence interval with a margin of error equal to 4.1.
Part 2 of 2
(b) If the required confidence level were 95%, would the necessary sample size be larger or smaller? (Choose one) V , because the confidence level is (Choose one) V .
Answer:
a) A sample of 198 must be drawn.
b) Smaller, because the confidence level is smaller.
Step-by-step explanation:
Question a:
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 - 0.999}{2} = 0.0005[/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 - 0.0005 = 0.9995[/tex], so Z = 3.291.
Now, find the margin of error M as such
[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]
How large a sample must be drawn so that a 99.9% confidence interval for u will have a margin of error equal to 4.1?
This is n for which M = 4.1. So
[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]
[tex]4.1 = 3.291\frac{17.5}{\sqrt{n}}[/tex]
[tex]4.1\sqrt{n} = 3.291*17.5[/tex]
[tex]\sqrt{n} = \frac{3.291*17.5}{4.1}[/tex]
[tex](\sqrt{n})^2 = (\frac{3.291*17.5}{4.1})^2[/tex]
[tex]n = 197.3[/tex]
Rounding up:
A sample of 198 must be drawn.
(b) If the required confidence level were 95%, would the necessary sample size be larger or smaller?
We have that:
[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]
Solving for n
[tex]\sqrt{n} = \frac{z\sigma}{M}[/tex]
That is, n and z are directly proportion, meaning that a higher value of z(higher confidence level) leads to a higher sample size needed.
95% < 99.9%, so a smaller confidence interval.
Smaller, because the confidence level is smaller.
