What is the value of x?
A. x = 94
B. x = 49
C. x = 86
D. x = 36
Answers
Answer: A
Step-by-step explanation: angle LJK says x subtract 8 degrees and since angle LJH is bigger than angle LJK the one over 90 degrees is the only logical one
Answer:
A. x = 94
Step-by-step explanation:
Add up angles to equal 180 because that is how much a line measures.
x + (x - 8) = 180
Simplify.
2x -8 = 180
Solve for x.
2x -8 = 180
+8 = +8
2x = 188
2 = 2
x = 94

ive manufacturer wants to know the proportion of new car buyers who prefer foreign cars over domestic. Step 2 of 2: Suppose a sample of 2017 new car buyers is drawn. Of those sampled, 484 preferred foreign over domestic cars. Using the data, construct the 95% confidence interval for the population proportion of new car buyers who prefer foreign cars over domestic cars. Round your answers to three decimal places.
Answers
Answer:
0.2305 ; 0.2495)
Step-by-step explanation:
Sample size, n = 2017
Number who preferred foreign over domestic cars, x = 484
Phat = 484 / 2017 = 0.2399603 = 0.240
The confidence interval :
Phat ± Margin of error
Margin of Error = Zcritical * √(phat(1-phat)/n)
Zcritical at 95% = 1.96
1 - phat = 1 - 0. 240 = 0.76
Margin of Error = 1.96 * √((0.240*0.76)/2017) = 0.0095095
Confidence interval :
Lower boundary : 0.240 - 0.0095 = 0.2305
Upper boundary : 0.240 + 0.0095 = 0.2495
(0.2305 ; 0.2495)

They will walk 6 laps and run 10 laps for a total of 16 miles considering each lap is of 1 mile.
What is mile?The mile is a customary unit of measurement in both the United States and the United Kingdom that is based on the older English unit of length equal to 5,280 English feet, or 1,760 yards. It is also referred to as the international mile or statute mile to distinguish it from other miles.
In 1959, the statute mile was formally redefined with respect to SI units as exactly 1,609.344 metres, establishing a standard between the British Commonwealth and the United States.
With qualifications, mile is also used to describe or translate a wide range of units derived from or approximately comparable to the Roman mile, such as the nautical mile (now exactly 1.852 km), the Italian mile (roughly 1.852 km), and the Chinese mile (now 500 m exactly).
6 laps + 10 laps = 16 laps
1 mile each laps = 16 miles

How many solutions does 10+5x=5x+10 have?
Answers
10 + 5x = 5x + 10
Reorder the terms:
10 + 5x = 10 + 5x
Add '-10' to each side of the equation.
10 + -10 + 5x = 10 + -10 + 5x
Combine like terms: 10 + -10 = 0
0 + 5x = 10 + -10 + 5x
5x = 10 + -10 + 5x
Combine like terms: 10 + -10 = 0
5x = 0 + 5x
5x = 5x
Add '-5x' to each side of the equation.
5x + -5x = 5x + -5x
Combine like terms: 5x + -5x = 0
0 = 5x + -5x
Combine like terms: 5x + -5x = 0
0 = 0

A Norman window is a window with a semi-circle on top of regular rectangular window. (See the picture.) What should be the dimensions of the rectangular part of a Norman window to allow in as much light as possible, if there are only 12 ft of the frame material available? I'm reporting you if you send be a bitly link
Answers
Answer:
length = 4 feet, and width = 2 feet
Step-by-step explanation:
Given that 12 feet of the frame material is available for the rectangular part of Norman's window. Then,
Perimeter = 2 (length + width)
Perimeter of the frame = 12 feet
So that,
Perimeter = 2 (length + width)
12 = 2 (length + width)
length + width = [tex]\frac{12}{2}[/tex]
length + width = 6 feet
Therefore, to allow much light as possible, the dimensions of the window would be; length = 4 feet, and width = 2 feet.
Seven television sets are chosen at random (i.e without replacement) from a shipment of 240 television sets of which 15 are defective. Calculate the probability that at least 1 of the chosen televisions are defective
Answers
Answer:
7/16
Step-by-step explanation:
Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.
For example, the probability that it would rain on Friday is between o and 1. If it rains, a value of one ids attached to the event. If it doesn't a value of zero is attached to the event.
Proportion of defective televisions in the shipment = 15/240 = 1/16
Probability that 1 of the 7 chosen is defective = 1/16 x 7 = 7/16

C) range: {-3, 1, 5, 7}
D) domain: {-3, 1, 5, 7}
Answers
The domain and range of the function on the table are the ones in options B and C.
Domain: {-3, 1, 5, 7}
Range: {2, 4, 5, 9}
How to find the domain and range of the function?For a function y = f(x), we define the domain as the set of the inputs, this is, the set of the possible values of x.
On the other hand, the range is the set of the outputs, this is, the set of the possible values of y.
Then the domain is just the set of the values of x on the table:
Domain: {-3, 1, 5, 7}
And the range is the set of the values of y on the table:
Range: {2, 4, 5, 9}
Then the correct options are C and B.
