Find the area of the trapezoid. Round your answer to the nearest hundredth.
Answer:
42.50 units²
Step-by-step explanation:
Area of the trapezoid = ½(AB + DC)×AD
AB = 6
DC = 11
AD = ?
Use trigonometric function, TOA to find AD:
Tan 45 = Opp/Adj
Opp = AD
Adj = 11 - 6 = 5
Tan 45 = AD/5
5 × tan 45 = AD
AD = 5
✔️Find Area of trapezoid.
Area = ½(AB + DC)×AD
= ½(11 + 6)×5
= 42.50 units²
Clint is going to open up a private practice where he will make $100 per client that he sees. How many clients does he have to see each week to earn $50,000, assuming he works 48 weeks per year? (Round to two decimal places)
Answer:
10 clients per week
Step-by-step explanation:
We know that there are 4 week in a month
48/4 = 12
And we know that there are 30 days in a month.
12*30 = 360
There are 365 days in a year
360x = 50,000
x = 139 (rounded)
We know he makes $100 per clients
139*100 = $13,900
To get to $50,000 we must divide
50,000 / 13,900 = 3.6
Now multiple 139 by 3.6
139*3.6 = 500
Divide by the week worked
500/48 = 10 (rounded)
So....
48 weeks * 10 clients = 480 total clients he saw
480 clients saw * $100 = $48,000
Clint needs to see 10.42 clients each week to earn $50,000 a year.
What is a unitary method?A unitary method is a mathematical way of obtaining the value of a single unit and then deriving any no. of given units by multiplying it with the single unit.
Given, Clint makes $100 per client that he sees.
∴ He needs to see (50000/100) clients to make $50,000.
= 500 clients per year.
Also given, he works 48 weeks a year.
∴ He needs to see (500/48) clients each week.
= 10.42 clients each week.

Of the 16 children in the park, seven-eighths are wearing a red shirt. How many children in the park are wearing a red shirt?
Answer:
14 children are wearing a red shirt in the park.
Step-by-step explanation:
The fraction 7/8 is 7 out of 8 but your total kids is 16 so we can go ahead and multiply by 2.
(7*2)/(8*2)
14/16
So now it's 14 out of 16 kids which is the total you have.
Conclusion: 14 Children are wearing a red shirt in the park.
Two investments totaling $15,500 produce an annual income of $1450. One investment yields 10% per year, while the other yields 5% per year. How much is invested at each rate?
Answer:10% rate:
Principal = p
Rate = 0.10
Interest = 0.10p
5% rate:
Principal = 15500 - p
Rate = 0.05
Interest = 0.05(15500 - p) = 775 - 0.05p
0.10p + (775 - 0.05p) = 1450
0.05p + 775 = 1450
0.05p = 675
p = 13500
10% rate:
Principal = p = $13,500
5% rate:
Principal = 15500 - p = 15500 - 13500 = $2000

Quadrilateral IJKL is dilated by a scale factor of to form quadrilateral I'J'K'L'. What
is the measure of side LI?
Answer:
The measurement of side LI = 24
Step-by-step explanation:
In the question, it is given that Quadrilateral IJKL is reduced to quadrilateral I'J'K'L' which is 1/2 the times of measurement of side of the Quadrilateral IJKL
I'L' = 12
And IL will be 2 times the measurement of I'L'
Hence, IL = 2*12 = 24
A researcher is interested in estimating the mean weight of a semi tracker tractor truck to determine the potential load capacity. She takes a random sample of 17 trucks and computes a sample mean of 20,000 pounds with sample standard deviation of 1,500. The 95% confidence interval for the population mean weight of a semi tracker tractor truck is ______________.
Answer:
(19228.737 ; 20771.263)
Step-by-step explanation:
Given that:
Sample size, n = 17
Sample mean, m = 20,000
Sample standard deviation, s = 1500
α = 95%
The confidence interval,
Mean ± margin of error
Margin of Error : Tcritical * s/sqrt(n)
Tcritical at α = 0.05 ; df = n-1 = 17 - 1 = 16 ; 2 - tailed test = 2.120
Margin of Error = 2.120 * 1500/sqrt(17) = 771.263
Lower boundary :
20,000 - 771.263 = 19228.737
Upper boundary :
20,000 + 771.263 = 20771.263
Confidence interval :
(19228.737 ; 20771.263)
One of the following is a regression example for which Entity and Time Fixed Effects could be used: ________
a. minimum wages on teenage employment using annual data from the 48 contiguous states in 2006.
b. various performance statistics on the (log of) salaries of baseball pitchers in the American League and the National League in 2005 and 2006.
c. inflation and inflationary expectations on unemployment rates in the United States, using quarterly data from 1960-2006.
d. drinking alcohol on the GPA of 150 students at your university, controlling for incoming SAT scores.
Answer:
b
Step-by-step explanation:
The regression which comprises of both entity & time effect can be expressed as;
[tex]Y_{it} = B_1X_{it} + \alpha_i + \lambda_i + \mu_{it}[/tex]
Where;
take charge of the state-explicit qualities that don't change over the long run
controls the variables that differ after some time yet not across substances,
[tex]u_{it}[/tex] controls state-specific qualities which shift after some time.
Thus, from the options given above:
The first option lacks or does not involve the time effect as we are only looking for a particular year.
The second option comprises only 2 years of data which implies that we have a time effect involved. In addition to that, there exist a few variables in executing measurements that join fixed effects. In this case, we can utilize regression with time and fixed effect.
(c) The information here is quarterly over an extended period of time. Hence, it would prefer a period arrangement information than a fixed and time impact information. Thus, this is incorrect.
(d) Since no time variable is associated, we reject the option.

During an economic downturn, 11 companies were sampled and asked whether they were planning to increase their workforce. Only 2 of the 11 companies were planning to increase their workforce. Use the small-sample method to construct an 80% confidence interval for the proportion of companies that are planning to increase their workforce. Round the answers to at least three decimal places.
An 80% confidence interval for the proportion of companies that are planning to increase their workforce is _______ < p< ________
Answer:
An 80% confidence interval for the proportion of companies that are planning to increase their workforce is 0.033 < p < 0.331.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which
z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].
Only 2 of the 11 companies were planning to increase their workforce
This means that [tex]n = 11, \pi = \frac{2}{11} = 0.182[/tex]
80% confidence level
So [tex]\alpha = 0.2[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.2}{2} = 0.9[/tex], so [tex]Z = 1.28[/tex].
The lower limit of this interval is:
[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.182 - 1.28\sqrt{\frac{0.182*0.818}{11}} = 0.033[/tex]
The upper limit of this interval is:
[tex]\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.182 + 1.28\sqrt{\frac{0.182*0.818}{11}} = 0.331[/tex]
An 80% confidence interval for the proportion of companies that are planning to increase their workforce is 0.033 < p < 0.331.

(numerator times numerator)/(denominator times denominator).
(2 * 11)/(5 * 4)
22/20
We can now reduce this fraction to the lowest terms.
The greatest factor of 22 and 20 is 2.
22 divided by 2 = 11.

From a train station, one train heads north, and another heads east. Some time later, the northbound train has traveled 12 miles, and the eastbound train has traveled 16 miles. How far apart are the two trains, measured in a straight line?
9514 1404 393
Answer:
20 miles
Step-by-step explanation:
The north and east distances form the legs of a right triangle. The straight-line distance between the trains is the hypotenuse of that triangle. The Pythagorean theorem can be used to find the length of the hypotenuse (d).
d² = 12² +16²
d² = 144 +256 = 400
d = √400 = 20
The two trains are 20 miles apart.
__
Additional comment
You may recognize the given distances are in the ratio 3 : 4. You may recall that side ratios of 3 : 4 : 5 make a right triangle. If so, you recognize that the straight-line distance is (4 miles)×5 = 20 miles. (3:4:5 right triangles show up often in algebra and geometry problems, so might be something you want to look for.)
Two alloys A and B are being used to manufacture a certain steel product. An experiment needs to be designed to compare the two in terms of maximum load capacity in tons (the maximum weight that can be tolerated without breaking). It is known that the two standard deviations in load capacity are equal at 5 tons each. An experiment is conducted in which 30 specimens of each alloy (A and B) are tested and the results recorded as follows:
x¯A = 49.5, x¯B = 45.5, x¯A − x¯B = 4
The manufacturers of alloy A are convinced that this evidence shows conclusively that muA & muB and strongly supports the claim that their alloy is superior. Manufacturers of alloy BB claim that the experiment could easily have given x¯A − x¯B = 4 even if the two population means are equal. In other words, "the results are inconclusive!"
(a) Make an argument that manufacturers of alloy B are wrong. Do it by computing
P(x¯A − x¯B > 4 | muA - muB
(b) Do you think these data strongly support alloy A?
Answer:
Step-by-step explanation:
From the given information, we can compute the table showing the summarized statistics of the two alloys A & B:
Alloy A Alloy B
Sample mean [tex]\bar {x} _A = 49.5[/tex] [tex]\bar {x} _B = 45.5[/tex]
Equal standard deviation [tex]\sigma_A = 5[/tex] [tex]\sigma_B= 5[/tex]
Sample size [tex]n_A = 30[/tex] [tex]n_{B}= 30[/tex]
Mean of the sampling distribution is :
[tex]\mu_{\bar{X_1}-\bar{X_2}}= 49.5-45.5 \\ \\ = 4.0[/tex]
Standard deviation of sampling distribution:
[tex]\sigma_{\bar{x_1}-\bar{x_2} }= \sqrt{\sigma^2_{\bar{x_1}-\bar{x_2} }} \\ \\ = \sqrt{\dfrac{\sigma_1^2}{n_1} + \dfrac{\sigma^2_2}{n_2} } \\ \\ =\sqrt{\dfrac{25}{30}+\dfrac{25}{30}} \\\\=\sqrt{1.667} \\ \\ =1.2909[/tex]
Hypothesis testing.
Null hypothesis: [tex]H_o: \mu_A -\mu_B = 0[/tex]
Alternative hypothesis: [tex]H_A:\mu_A -\mu_B > 4[/tex]
The required probability is:
[tex]P(\overline X_A - \overline X_B>4|\mu_A - \mu_B) = P\Big (\dfrac{(\overline X_A - \overline X_B)-\mu_{X_A-X_B}}{\sigma_{\overline x_A -\overline x_B}} > \dfrac{4 - \mu_{X_A-\overline X_B}}{\sigma _{\overline x_A - \overline X_B}} \Big) \\ \\ = P \Big( z > \dfrac{4-0}{1.2909}\Big) \\ \\ = P(z \ge 3.10)\\ \\ = 1 - P(z < 3.10) \\ \\ \text{Using EXCEL Function:} \\ \\ = 1 - [NORMDIST(3.10)] \\ \\ = 1- 0.999032 \\ \\ 0.000968 \\ \\ \simeq 0.0010[/tex]
This implies that a minimal chance of probability shows that the difference of 4 is not likely, provided that the two population means are the same.
b)
Since the P-value is very small which is lower than any level of significance.
Then, we reject [tex]H_o[/tex] and conclude that there is enough evidence to fully support alloy A.

use the distributive property to multiply 3(-2m+1)
Answer:
-6m+3
Step-by-step explanation:
"use the distributive property to multiply 3(-2m+1)"
--------------------------------------------------------------------------------------------------------------
The distributive property states that the product of an expression and a sum is equal to the sum of the products of the expression and each term in the sum. For example, a(b + c) = ab + ac. The division property of inequality states that two unequal values divided by a positive number retain the same relationship.
--------------------------------------------------------------------------------------------------------------
We can simplify this into-
3(-2m) + 3(1)
Now, we can multiply.
-6m + 3
