Answer:
x = 61
Step-by-step explanation:
Formula:
(N {which is the number of sides in the polygon] - 2) * 180 = the sum of all the angles in the polygon.
Simply add the known angles together, subtract that from the above equation and you get the value of x.
(5 {which is N] - 2) * 180
3 * 180 = 540
82 + 121 + 129 + 147 = 479
540 - 479 = x
540 - 479 - 61
x = 61

Jolly measured the cake. Then she calculated that it has a circumference of 15cm. what is the cake's diameter? Use 3.14 for pi.
Will mark brainlest.
Answer:
4.76cm
Step-by-step explanation:
Given data
circumference= 15cm
The expression for circumference is
C= 2πr
substitute and solve for r
15= 2*3.14*r
r= 15/ 2*3.14
r=15/ 6.28
r= 2.38 cm
Hence the diameter is
D= 2r
D= 2*2.38
D=4.76cm

Answer:
31/15
Step-by-step explanation:
First, find the common multiplier of 20 and 12 (the lowest number that both fractions can be increased to). This is 60 (12 x 5 = 60, 20 x 3 = 60) and adjust the numerators accordingly: multiply 17 by five to get 85, and multiply 13 by three to get 39. Add them up to get 124/60, and then simplify - the answer will be 31/15! Hope this helps! Sorry if this was tough to understand, typing off my phone, so feel free to ask any questions :)

Peele is interested in the average price of an entree at a French restaurant, but only has a random sample of 9 prices (prices are not listed on the menu). Using this random sample, Key calculates that a 90% confidence interval for the true mean is given by (65, 88). (You can assume the prices follow a normal distribution). Use this information to do the following:
a) Calculate 7. (Hint, what does a confidence interval look like?)
b) Calculate s.
c) Construct a 95% confidence interval for the true mean price of all the entrees, f.
Answer:
Xbar = 76.5
s = 24.70
(61.19 ; 91.81)
Step-by-step explanation:
Given that :
Confidence interval = (65, 88)
Recall:
Confidence interval = xbar ± margin of error
Margin of Error = (upper boundary - lower boundary) / 2
Margin of Error = (88 - 65) /2 = 11.5
Taking the lower boundary :
Lower boundary = xbar - margin of error
xbar = lower boundary + margin of error
Xbar = 65 + 11.5
Xbar = 76.5
Margin of Error = Tcritical * s/sqrt(n)
s = sample standard deviation
Tcritical at 90% confidence, df = 9-1= 8 = 1.397
11.5 = 1.397 * s/sqrt(9)
11.5 = 1.397 * s/3
34.5 = 1.397s
s = 34.5 / 1.397
s = 24.695
s = 24.70
C.) 95% confidence interval :
Tcritical at 95%, df = 8 = 1.860
Margin of Error = 1.860 * 24.70/sqrt(9) = 15.311
Confidence interval :
Lower boundary = 76.5 - 15.311
Upper boundary = 76.5 + 15.311
(61.19 ; 91.81)

Find four rational numbers between -3/2 and 5/3
Answer:
Four rational numbers between [tex]-\frac{3}{2}[/tex] and [tex]\frac{5}{3}[/tex] are [tex]x_{1} = -\frac{13}{15}[/tex], [tex]x_{2} = -\frac{7}{30}[/tex], [tex]x_{3} = \frac{2}{5}[/tex] and [tex]x_{4} = \frac{31}{30}[/tex].
Step-by-step explanation:
First, we calculate the distance between [tex]-\frac{3}{2}[/tex] and [tex]\frac{5}{3}[/tex]:
[tex]r = \frac{5}{3}-\left(-\frac{3}{2}\right)[/tex]
[tex]r = \frac{5}{3}+\frac{3}{2}[/tex]
[tex]r = \frac{10+9}{6}[/tex]
[tex]r = \frac{19}{6}[/tex]
Then, we find four rational numbers by using the following formula:
[tex]x = -\frac{3}{2}+\left(\frac{n}{5})\cdot \left(\frac{19}{6} \right)[/tex]
First number ([tex]n = 1[/tex])
[tex]x_{1} = -\frac{13}{15}[/tex]
Second number ([tex]n = 2[/tex])
[tex]x_{2} = -\frac{7}{30}[/tex]
Third number ([tex]n = 3[/tex])
[tex]x_{3} = \frac{2}{5}[/tex]
Fourth number ([tex]n = 4[/tex])
[tex]x_{4} = \frac{31}{30}[/tex]
Oriole Rental Company provided the following information to its auditors. For the year ended March 31, 2017, the company had revenues of $876,223, general and administrative expenses of $352,479, depreciation expenses of $131,455, leasing expenses of $108,195, and interest expenses equal to $78,122. If the company's average tax rate is 34 percent, what is the cash flow from operating activity for Oriole Rental? (Round intermediate calculations and final answer to the nearest whole dollar, e.g. 5,275.) Cash flow from operation
Answer:
the cash flow from operation is $267,397
Step-by-step explanation:
Given that
Revenues be $876,223
General and admin expense $352,479
Depreciation expense $131,455
Leasing expense $108,195
Interest expense $78,122
Tax rate is 34%
We need to find out the cash flow from operation
As we know that
Cash flow from operation = (Revenue - general & admin expense - depreciation - leasing - interest) × (1 - tax rate) + depreciation
= ($876,223 - $352,479 - $131,455 - $108,195 - $78,122) × (1 - 0.34) + $131,455
= $205,972 × (1 - 0.34) + $131,455
= $267,397
Hence, the cash flow from operation is $267,397

Brian Vanecek, VP of Operations at Portland Trust Bank, is evaluating the service level provided to walk-in customers. Accordingly, his staff recorded the waiting times for 45 randomly selected walk-in customers, and calculated that their mean waiting time was 15 minutes. If Brian concludes that the average waiting time for all walk-in customers is 15 minutes, he is using a ________.
Answer:
statistical parameter
Step-by-step explanation:
In this scenario, Brian Vanecek is using a statistical parameter also known as a population parameter. This is the best explanation to what Brian is using since he is calculating the average waiting time based on the information gathered from a randomly selected sample of the population. Since this sample was random it exemplifies the entire population and therefore allows for the data to be generalized to that population. Using the statistics gathered he can calculate the average waiting time as a statistical parameter of the population.

A carbon filter is used by a scientist to filter out small particles of soil and rocks from
a water sample taken from a stream. The exponential function F(x) = 500(0.35) can
be used to model the function. Which of the following could be represented by the
value 500 in the function rule?
Answer:
The number of particles of soil and rock particles found in the water.
Step-by-step explanation:
Since we are filtering out small particles of soil and rocks, then we can assume that they are being reduced greatly with each filter. So we can assume that since the 500 is being reduced by 65%, then the 500 is the only other thig being reduced, which in this case is the particles of soil and rocks.

The Damon family owns a large grape vineyard in western New York along Lake Erie. The grapevines must be sprayed at the beginning of the growing season to protect against various insects and diseases. Two new insecticides have just been marketed: Pernod 5 and Action. To test their effectiveness, three long rows were selected and sprayed with Pernod 5, and three others were sprayed with Action. When the grapes ripened, 400 of the vines treated with Pernod 5 were checked for infestation. Like- wise, a sample of 400 vines sprayed with Action were checked. The results are: EXERCISES Republicans Democrats Number sampled 1,000 800 Number in favor 200 168 Number of Vines Checked Number of Insecticide (sample size) Infested Vines Pernod 5 400 24 Action 400 40 At the .05 significance level, can we conclude that there is a difference in the pro- portion of vines infested using Pernod 5 as opposed to Action
Answer:
Please find the attached file of the complete question:
Step-by-step explanation:
Given:
[tex]Pernod \ 5: n_1= 400\\\\ p_1=\frac{29}{400}=0.0725\\\\Action: \ n_2= 400\\\\ p_2=\frac{38}{400}= 0.095\\\\[/tex]
Calculating the value of the test hypothesis:
[tex]H_{O} \ :p_1-p_2=0\\\\ \ H_{a}:p_1-p_2 \neq 0[/tex]
Let [tex]a=0.02[/tex] is the critical value [tex]Z(0.01)= -2.33[/tex]
[tex]H_0[/tex] rejects when[tex]z <-2.33 \ \ or\ \ z >2.33 .[/tex]
Calculating the Pooled proportion:
[tex]= \frac{(29+38)}{(400+400)}\\\\ = \frac{(67)}{(800)} \\\\ = 0.08375\\\\=0.084[/tex]
