In circle O, central angle COD has a measure of 48. Find the measure of arc BC. In your final answer, include all your work
Answers
Answer:
Measure of arc BC = 132°
Step-by-step explanation:
Measure of the central angle COD = 48°
Therefore, measure of arc AB = 48°
Since, segment AC is a diameter and central angle for a diameter is 180°.
Measure of major arc ABC = 180°
measure of arc AB + measure of arc BC = 180°
48° + measure of arc BC = 180°
Measure of arc BC = 180° - 48°
= 132°

2,995 or 35,940(?)
Step-by-step explanation:
I don't exactly remember how to do this so, I'll show you two different ways I solved this
Use the formula I=P*r*t
I=Interest
P=Principal
r=rate
t=time
To solve this you'll have to...
The principal is 29,950, the rate is 5% but it'll become a decimal which is 0.05, and the time is 2
Put it into the formula form 29,950*0.05*2= 2,995 in interest
Or...
You'll use the same formula, but this time multiply 0.05 by 12 since there are 12 months in one year which is 0.6, so...
29,950*0.6*2=35,940 in interest

Answers
Step-by-step explanation:
hope it will help you......
Answer:
p = 17
Step-by-step explanation:
→ Expand out (21)² - (17)²
21² = 441 and 17² = 289 therefore 441 - 289 = 152
→ Plug value back into equation
441 - p² = 152
→ Minus 441 from both sides
- p² = -289
→ Square root both sides
p = 17

Answers
Answer:
1. a. z test for means and t test for means.
2. C. HA : mu1 - mu2 > 0
Step-by-step explanation:
Hypothesis testing is used in a situation where there are more than 1 alternative available. The t test is conducted in the mean which determines the t value and then this value is compared with p value to identify the situation whether to accept or reject the null hypothesis. The alternative hypothesis in this situation is is represented by mu.

A) 1,812
B) 6,988
C) 6,188
D) 7,200
Answers
The answer will be option B. The net pay for the jacob will be equal to $6,188.
What is gross pay?The amount paid by any company to the employees without any deductions like taxes or charges is called as the gross pay.
It is given that:-
Gross pay for the year was $8000
The federal tax rate he’ll need to pay is 10%.
Jacob will need to pay 5% and the FICA rate is 7.65%
So the total deductions from the gross pay will be calculated as:-
Deductions = 8000 X 10% +8000 x 5% +8000 x 7.5%
Deductions = 800+400+612=$1812
The net pay will be = 8000-1812 =$ 6188
Hence the net pay for the jacob will be equal to $6,188.

The botanist would like to estimate the average weight of mustard seeds grown in a certain type of soil; weight of the seeds is known to follow a normal distribution. The botanist collects a random sample of 10 mustard seeds and finds that the sample average and sample standard deviation are 528 mg and 49 mg respectively. Select from the following the correct 90% confidence interval for the true average weight of mustard seeds grown in Soil Type A using the above sample data.
a. (480.1, 539.9)
b. (525.2, 534.8)
c. (479.4, 540.6)
d. (473.6, 546.4)
e. The necessary assumptions have not been satisfied and the calculation cannot be performed.
f. (469.4, 550.6)
Answers
Answer:
The correct 90% confidence interval for the true average weight of mustard seeds grown in Soil Type A using the above sample data is (499.6, 556.4).
Step-by-step explanation:
We have the standard deviation for the sample, so we use the t-distribution to solve this question.
T interval
The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So
df = 10 - 1 = 9
90% confidence interval
Now, we have to find a value of T, which is found looking at the t table, with 9 degrees of freedom(y-axis) and a confidence level of [tex]1 - \frac{1 - 0.9}{2} = 0.95[/tex]. So we have T = 1.833
The margin of error is:
[tex]M = T\frac{s}{\sqrt{n}} = 1.833\frac{49}{\sqrt{10}} = 28.4[/tex]
In which s is the standard deviation of the sample and n is the size of the sample.
The lower end of the interval is the sample mean subtracted by M. So it is 528 - 28.4 = 499.6 mg
The upper end of the interval is the sample mean added to M. So it is 528 + 28.4 = 556.4 mg
The correct 90% confidence interval for the true average weight of mustard seeds grown in Soil Type A using the above sample data is (499.6, 556.4).

I have attached an image showing the triangle with angle and distance depicted in the question.
Answer:
151 miles
Step-by-step explanation:
We have to first find the unknown angle in the triangle.
Sum of angles in a triangle is 180°.
Thus, if we call angle at Norfolk A, we have;
A = 180 - (83 + 31)
A = 66°
Using sine rule, we can find the distance which we will term as a.
Thus;
a/sin 83 = 139/sin 66
a = (139 × sin 83)/sin 66
a = 137.963915/0.913545
a ≈ 151 miles

x denotes the variable
a denotes the constant
So according to the given options, the option C would represent the exponential function

A certain process for manufacturing integrated circuits has been in use for a period of time, and it is known that 12% of the circuits it produces are defective. A new process that is supposed to reduce the proportion of defectives is being tested. In a simple random sample of 100 circuits produced by the new process, 11 were defective.
a. If the proportion of defectives in the sample is less than 12%, it is reasonable to conclude that the new process is better.
1. True
2. False
b. If the proportion of defectives in the sample is only slightly less than 12%, the difference could be due entirely to sampling variation, and it's not reasonable to conclude that the new process is better.
1. True
2. False
c. If the proportion of defectives in the sample is a lot less than 12%, it is very unlikely that the difference is due entirely to sampling variation, so it is reasonable to conclude that the new process is better.
1. True
2. False
Answers
Answer:
a. If the proportion of defectives in the sample is only slightly less than 12%, the difference could be due entirely to sampling variation, and it's not reasonable to conclude that the new process is better
b. True
c. True
Step-by-step explanation:
a. The percentage of defective circuits produced = 12%
Given that the percentage of defective circuits produced in the new process is 11% which is only slightly less than the observed 12%, the difference may be due to variation in the sample, as another sample of 100 in the new process cold produce more than 11 defective circuits
b. True. In every sample, there is a slight variation which can account for the difference
c. Given that the defectives in the sample is considerably less than 12%, then it would be more statistically evident that there is a difference in the two processes and the new process can be considered reasonably better
Therefore, the answer is; True
