Step-by-step explanation:
1) AGI deductions are subtracted from the gross income to calculate the taxable income. Not all the individual's earnings are subject to taxation, therefore some expenses are deducted to calculate the Adjusted Gross Income, the one that will be taxed.
All of the three options listed ( Standard deduction, Itemized deduction, and personal exemption) are AGI deductions.
2) False
The potential qualifying relative does not have to be family/biologically related with the taxpayer. The IRS condition states that he/she is either family related or have lived in the taxpayer's abode for a whole year to be a qualified relative of the taxpayer. So far any of the two conditions are met, it is fine.
C. For a student to be regarded as a qualifying relative of her parents, she must not be up to 24 years at the end of the year according to IRS. Jane is already 25, she is too old and fails the test as a qualifying relative.
A recreational equipment supplier inds that among orders that include tents, 40% also include sleeping mats. Only 5% of orders that do not include tents do include sleeping mats. Also, 20% of orders include tents. Determine the following probabilities:
a. The order includes sleeping mats.
b. The order includes a tent given it includes sleeping mats.
Answer:
a. 12%
b. 2/3
Step-by-step explanation:
Given data regarding orders that do and don't include tents and/or mats, you want to find the probabilities of (a) the order includes mats; (b) the order includes a tent given that it includes mats.
Two-way tableThe given data is summarized in the attached two-way table. The value in blue is given in the problem statement. The values in purple are computed from values given in the problem:
40% of the 20% of orders include a tent and mat = 8% of orders
5% of the 80% of orders with no tent = 4% of orders include a mat
The numbers in black make the totals come out right.
a. Includes matThe table shows that 8% +4% = 12% of all orders include sleeping mats.
P(m) = 12%
b. Includes tent, given includes mats8% of the 12% of orders that include mats also include a tent. The probability of an order including a tent given that it includes a mat is ...
P(t|m) = 8%/12% = 2/3
Alicia drove at a constant speed and traveled 182.4 miles in 3 hours. How many miles
would Alicia travel in 11 hours at the same speed?
Answer:
[tex] V = \frac{182.4 mi}{3 hr}= 60.8 \frac{mi}{hr}[/tex]
And then we can find the distance travelled in 11 hours with this formula:
[tex] D = Vt[/tex]
And replacing we got:
[tex] D = 60.8 \frac{mi}{hr} *11 hr =668.8 mi[/tex]
So then after 11 hours she will travel 668.8 mi
Step-by-step explanation:
For this case w eknow that Alicia drove at a constant speed 182.4 mi in 3 hours. We can find the speed with this formula:
[tex] V= \frac{D}{t}[/tex]
Where V is the velocity, D the distance and t the time if we replace we got:
[tex] V = \frac{182.4 mi}{3 hr}= 60.8 \frac{mi}{hr}[/tex]
And then we can find the distance travelled in 11 hours with this formula:
[tex] D = Vt[/tex]
And replacing we got:
[tex] D = 60.8 \frac{mi}{hr} *11 hr =668.8 mi[/tex]

The number of miles a motorcycle, X, will travel on one gallon of gasoline is modeled by a normal distribution with mean 44 and standard deviation 5. If Mike starts a journey with one gallon of gasoline in the motorcycle, find the probability that, without refueling, he can travel more than 50 miles. Round your answer to four decimal places.
Answer:
[tex]P(X>50)=P(\frac{X-\mu}{\sigma}>\frac{50-\mu}{\sigma})=P(Z>\frac{50-44}{5})=P(z>1.2)[/tex]
And we can find this probability using the normal standar distribution and with the complement rule we got:
[tex]P(z>1.2)=1-P(z<1.2) =1-0.8849= 0.1151[/tex]
Step-by-step explanation:
Let X the random variable that represent the number of miles a motorcycle of a population, and for this case we know the distribution for X is given by:
[tex]X \sim N(44,5)[/tex]
Where [tex]\mu=44[/tex] and [tex]\sigma=5[/tex]
We are interested on this probability
[tex]P(X>50)[/tex]
And we can use the z score formula given by:
[tex]z=\frac{x-\mu}{\sigma}[/tex]
And using this formula we got:
[tex]P(X>50)=P(\frac{X-\mu}{\sigma}>\frac{50-\mu}{\sigma})=P(Z>\frac{50-44}{5})=P(z>1.2)[/tex]
And we can find this probability using the normal standar distribution and with the complement rule we got:
[tex]P(z>1.2)=1-P(z<1.2) =1-0.8849= 0.1151[/tex]

Answer:
m = 13.
Step-by-step explanation:
Recall that adding logarithmic equations, (ex: log a + log b) is the same as log (a·b). Therefore:
log 12 + log 5 = log (4m + 8)
log (12·5) = log (4m + 8)
log (60) = log (4m + 8) **Ignore 'Log' to solve for 'm'
60 = 4m + 8 **Subtract both sides by 8
52 = 4m **Divide both sides by 4
m = 13.

Aunt Ga Ga gave you $5,500 to save for college. You deposit the money in a savings account that earns 4% annual interest, compounded quarterly. (Show your work for each question)
a. Write an exponential function to model this situation. Define your variables.
b. What will the value of the account be after 2 years?
c. how long would it take the account to be worth $10,000?
Answer:
(a)[tex]A(n)=5500(1.01)^{4n}[/tex]
(b)$5955.71
(c)15.02 years
Step-by-step explanation:
For an initial principal P deposited in an account at an annual interest r compounded for a number of period k, the amount in the account after n years is given by the model:
[tex]A(n)=P(1+\dfrac{r}{k})^{nk}[/tex]
(a)Aunt Ga Ga gave you $5,500 to save for college.
P=$5,500
Annual Interest, r=4%=0.04
Since interest is compounded quarterly, Number of Periods, k=4
Therefore, an exponential function modeling this situation is:
[tex]A(n)=5500(1+\dfrac{0.04}{4})^{4n}\\A(n)=5500(1+0.01)^{4n}\\$Simplified\\A(n)=5500(1.01)^{4n}[/tex]
(b)After 2 years, i.e. when n=2
[tex]A(2)=5500(1.01)^{4*2}\\=\$5955.71[/tex]
(c)When A(n)=$10000, we have:
[tex]10000=5500(1.01)^{4n}\\$Divide both sides by 5500\\(1.01)^{4n}=\dfrac{10000}{5500} \\$To solve for n, we change to logarithm form\\Log_{1.01}\dfrac{10000}{5500}=4n\\= \dfrac{ Log \dfrac{10000}{5500}}{Log 1.01}=4n\\4n=60.08\\n=60.08 \div 4\\n=15.02\\$Therefore, in 15.02 years, the account would be worth $10,000.[/tex]

MegaPhone Design Inc. designs megaphones with sport team stickers on opposite sides
of the megaphone. Estimate the percent of the surface area of the megaphone
covered by the stickers. Round to the nearest percent.
*see attachment for the megaphone being referred to here
Answer:
9%
Step-by-step explanation:
==>Given:
Conical megaphone with the following dimensions:
Slant height (s) = 2.25 ft
Diameter (D) = 1.2 ft (radius r = 0.6 ft)
π = 3.1
Area covered by sticker on one side = area of square = 6 in × 6 in = 0.5 ft × 0.5 ft = 0.25 ft²
==>Required
% of the surface of area of the conical megaphone that is covered by the sticker = area covered by the sticker ÷ surface area of megaphone × 100
==>SOLUTION
Area covered by sticker on both sides = 0.25 ft² + 0.25 ft² = 0.5 ft²
Surface area of the megaphone = surface area of a cone = πrs + πr²
S.A of megaphone = (3.14 × 0.6 × 2.25) + (3.14 × 0.6²)
S.A = 4.239 + 1.1304
S.A = 5.3694 ft²
Therefore, % of the surface of area of the conical megaphone that is covered by the sticker = 0.5 ÷ 5.3694 × 100
= 9.31202741
= 9%
Answer:
Statistics show the megaphone was a success in South Carolina.

At the airport, d airplanes flew away, and b were still there. How many more airplanes stayed at the airport than flew away?
Answer:
b-d
Step-by-step explanation:
At the airport, d airplanes flew away, and b were still there.
Number of airplanes which flew away =d Number of airplanes which stayed at the airport =bWe are required to determine how many more airplanes stayed at the airport than flew away.
To do this, we subtract the number of airplanes which flew away from the number which stayed.
Therefore:
Number of more airplanes which stayed than flew away
=Number of airplanes which stayed-Number of airplanes which flew away

Based on an indication that mean daily car rental rates may be higher for Boston than for Dallas, a survey of eight car rental companies in Boston is taken and the sample mean car rental rate is $47, with a standard deviation of $3. Further, suppose a survey of nine car rental companies in Dallas results in a sample mean of $44 and a standard deviation of $3. Use alpha = 0.05 to test to determine whether the average daily car rental rates in Boston are significantly higher than those in Dallas. Assume car rental rates are normally distributed and the population variances are equal. The null hypothesis for this problem is ______.
a) μ1 - μ2 < 0
b) μ1 - μ2 > 0
c) μ1 - μ2 = 1
d) μ1 - μ2 ≠ 0
e) μ1 - μ2 = 0
Answer:
Step-by-step explanation:
This is a test of 2 independent groups. The population standard deviations are not known. Let μ1 be the mean daily car rental rates for Boston and μ2 be the mean daily car rental rates for Dallas.
The random variable is μ1 - μ2 = difference in the mean daily car rental rates for Boston and the mean daily car rental rates for Dallas
We would set up the hypothesis.
The null hypothesis is
H0 : μ1 = μ2 H0 : μ1 - μ2 = 0
The alternative hypothesis is
H1 : μ1 > μ2 H1 : μ1 - μ2 > 0
Since sample standard deviation is known, we would determine the test statistic by using the t test. The formula is
(x1 - x2)/√(s1²/n1 + s2²/n2)
From the information given,
μ1 = 47
μ2 = 44
s1 = 3
s2 = 3
n1 = 8
n2 = 9
t = (47 - 44)/√(3²/8 + 3²/9)
t = 1.41
The formula for determining the degree of freedom is
df = [s1²/n1 + s2²/n2]²/(1/n1 - 1)(s1²/n1)² + (1/n2 - 1)(s2²/n2)²
df = [3²/8 + 3²/9]²/[(1/8 - 1)(3²/8)² + (1/9 - 1)(3²/9)²] = 4.515625/0.28571428571
df = 16
We would determine the probability value from the t test calculator. It becomes
p value = 0.09
Since alpha, 0.05 < than the p value, 0.09, then we would fail to reject the null hypothesis.

Shianne is looking up at the flag on the top of the sailboat she is sailing on. She is sitting 16 feet from the bottom
of the flag, and her line of sight is 58° from horizontal. Her eyes are 6 feet above the bottom of the sail boat.
To the nearest foot, how high up is the flag from the bottom of the sailboat?
Answer:
height of the flag from the bottom of the boat ≈ 32 ft (nearest foot)
Step-by-step explanation:
She is on her boat and the angle of elevation to the top of the flag is 58°. Her eyes her 6 ft above the bottom of the boat she is sailing on. The height of the flag from the bottom of the boat is the sum of the height of the flag and the remaining height from the horizontal line of sight upward to the flag top.
A right angle triangle was formed Shianne line of sight. The angle from her line of sight is 58° from the horizontal. Therefore,
the adjacent side of the triangle formed is 16 ft which is the distance from the boat to the flag.
adjacent side = 16 ft
opposite angle = ?
using tangential ratio
tan 58° = opposite/adjacent
tan 58° = h/16
cross multiply
h = 16 × 1.60033452904
h = 25.6053524647
height of the flag from the bottom of the boat = 25.6053524647 + 6 = 31.6053524647
