The SECA taxes for the income $57000 will be $7068.
What is SECA?SECA stands for Self Employed Contributions Act. These taxes are computed from the net earnings, which in this case is $57000.
The basic rate for SECA taxes is 6.2% for employeer and 6.2% for employee. In the case of people who are self employed, the taxes are double, because they are employee and employeer at the same time.
So, Doug have to pay 12.4% taxes, which is equivalent to:
[tex]\rm SECA=57000\times 12.4\%= $7067[/tex]
Therefore, the SECA deduction for Doug is $7068.

Use a t-distribution to answer this question. Assume the samples are random samples from distributions that are reasonably normally distributed, and that a t-statistic will be used for inference about the difference in sample means. State the degrees of freedom used.
Find the proportion in a t-distribution less than −1.4 if the samples have sizes n1=30 and n2=40.
Enter the exact answer for the degrees of freedom and round your answer for the area to three decimal places.
Using the t-distribution, it is found that the proportion in a t-distribution less than −1.4 if the samples have sizes n1=30 and n2=40 is of 0.083.
How to find a proportion in a t-distribution?The proportion is found using a calculator, with three inputs:
The tail of the test, if it is left, right, or two-tailed.The test statistic.The amount of degrees of freedom.In this problem, we have a left-tailed proportion, as we want the proportion that is less than a value, with test statistic t = -1.4 and 30 + 40 - 2 = 68 df, hence the proportion is of 0.083.

Parent function: [tex]f(x)=|x|[/tex]
The vertex of the parent function is at (0, 0) as [tex]f(0)=|0|=0[/tex]
From inspection of the graph, the vertex of the transformed function is at (3, 0). Therefore, there has been a translation of 3 units right:
[tex]\implies g(x)=f(x-3)=|x-3|[/tex]
(There has not been any vertical translation since the y-value of the vertex of the parent function and the translated function is the same)
From inspection of the graph, we can see that it has been stretched parallel to the y-axis:
[tex]\implies g(x)=a\:f(x-3)=a|x-3|[/tex]
The line goes through points (10, 2) and (-4, 2).
Substituting one of these points to find a:

if a rhombus has an area of 264 square units. If DB=12 units, find AC
Using the formula for calculating the area of a rhombus, the length of /AC/ is 44 units
Calculating the area of a RhombusFrom the question, we are to determine the length of AC
The area of a rhombus is given by
[tex]A = \frac{pq}{2}[/tex]
Where A is the area
p and q are the diagonals
Then, for the given diagram,
[tex]A = \frac{/DB/ \times /AC/}{2}[/tex]
From the given information,
A = 264 square units
/DB/ = 12 units
∴ [tex]264 = \frac{12\times /AC/}{2}[/tex]
[tex]264 = 6\times /AC/[/tex]
[tex]/AC/ = \frac{264}{6}[/tex]
/AC/ = 44 units

According to universal law of gravitation every object in the universe attracts every other particles that surrounds it with a force which is inversely proportional to the square of their distance of separation & directly proportional to
the product of their masses, given by standard formula.
[tex]A = G \cdot \frac{m_1.m_2}{ {d}^{2} } [/tex]

A2 = 8 units
To find:
Distance of separation when the force of attraction is 8 units d2 = ?
Solution:
Substituting the given values in above at each point,

Answer:
25/33
Step-by-step explanation:
Answer:
[tex]\frac{25}{33}[/tex]
Step-by-step explanation:
we require 2 equations with the repeating digits placed after the decimal point.
let x = 0.7575..... (1) ← multiply both sides by 100
100x = 75.7575... (2)
subtract (1) from (2) thus eliminating the repeating digits

a local pizzaria offers 15 toppings for their pizzas you can choose any 4 of them for a fixed price how many different types of pizzas can you order with 4 toppings
Since we can choose 4 of the 15 toppings, we can order 1365 different types of pizzas with 4 toppings
Since the question says 'choose', it is a combination question and order is not important.
What is combination?This is the number of ways in which x objects can be selected from n objects.
It is given mathematically as ⁿCₓ = n!/[r!(n - r)!]
Number of different types of pizzasNow given that we have 15 toppings for pizza and we want to choose any 4, So, we are choosing 15 toppings in 4 ways. So,
n = 15 and r = 4So, ¹⁵C₄ = 15!/4!(15 - 4)!
= 15!/4!11!
= 15 × 14 × 13 × 12 × 11!/4!11!
= 15 × 14 × 13 × 12/24
= 15 × 7 × 13

The equation is [tex]y = 2500*1.035^x[/tex] as it is in the form [tex]y = a*b^x[/tex]
Plug in y = 5000 and solve for x.
[tex]y = 2500*1.035^x\\\\5000 = 2500*1.035^x\\\\1.035^x = 5000/2500\\\\1.035^x = 2\\\\\log(1.035^x) = \log(2)\\\\x\log(1.035) = \log(2)\\\\x = \log(2)/\log(1.035)\\\\x \approx 20.148792\\\\x \approx 21\\\\[/tex]

t=10When Josiah buys a ticket at the local movie theater, he receives 100 reward points to use toward future purchases. He is offered a scratch-off card instead of the points, which will allow him to try for a higher point value. The three possible point awards on the scratch-off card are 25, 100, and 120. There is an equal number of cards for each point award in the stack he chooses the card from.
Which statement is true?
A
The best option is to take the 100 points because the expected value of the points from the scratch-off card is less than 100 points.
B
The best option is to take the scratch-off card because two of the three possible point values on the card are the same or greater than the 100 points.
C
The best option is to take the scratch-off card because the 120-point value that is on the card is greater than 100 points.
D
The best option is to take the 100 points because the probability of being awarded more than 100 points on the scratch-off card is zero.
The best option is to take the 100 points because the expected value of the points from the scratch-off card is less than 100 points option (A) is correct.
What is probability?It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words the probability is the number that shows the happening of the event.
Since, there is an equal number of cards of point 25, 100, and 120
P(x =25) = P(x =100) = P(x =200) = 1/3
x: 25 100 120
P(x): 1/3 1/3 1/3
The expected value is:
E(x) = 25×(1/3) + 100×(1/3) + 125×(1/3)
E(x) = 245/3 < 300/3 = 100
Thus, the best option is to take the 100 points because the expected value of the points from the scratch-off card is less than 100 points option (A) is correct.

Darren is making veggie burgers for his family. He will use all the burgers mix he made to form 4 burgers of equal weight. The recipe only makes 32 oz burger mix but Darren made more than that to make extra big burgers
Answer:
4 > 32
Step-by-step explanation:
The variable x represents how much each of Darren's burgers will weigh. Since he will form 4 burgers of equal weight, the expression 4x represents the total weight of the burgers.
And, since Darren will use more than 32 ounces of burger mix, 4x must be greater than 32.
This inequality shows the relationship.
4x > 32
Now, solve for x.
4x > 32
4x/4 32/4
divide 32 by 4
So the answer is x > 8
