The angle that will be formed by the cable based on the information given will be 15°.
How to calculate the angle?From the complete information, it's important to divide the total angle by 12. This will be:
= 360°/12 = 30°
Then, the relations that will be used will be:
= 1/2(60° - 30°)
= 1/2 × 30°
= 15°

y = -6x+2
-12x-2y = -4
How many solutions does this linear system have?
O one solution: (0, 0)
O one solution: (1,-4)
Ono solution
O infinite number of solutions
Answer:
infinite number of solutions
Step-by-step explanation:
Given equations:
y = -6x+2-12x - 2y = -4Rearrange the second equation to make y the subject:
⇒ -12x - 2y = -4
⇒ -12x - 2y + 2y = -4 + 2y
⇒ -12x = -4 + 2y
⇒ -12x + 4 = -4 + 2y + 4
⇒ -12x + 4 = 2y
⇒ (-12x + 4) ÷ 2 = 2y ÷ 2
⇒ y = -6x + 2
Comparing the rearranged equation with the first equation, we can see that both equations are the same.
Therefore, as there is only one line, there are an infinite number of solutions.

Jasmine deposited $700 in an account earning 9% interest compounded annually,
To the nearest cent, how much will she have in 1 year?
At the end of one year Jasmine will have the sum of $763
Calculation of interest rateThe principal amount (P)= $700
The interest rate(R) = 9%
The period of investment (T) = 1 year
Therefore simple interest
= P×T×R/100
= 700×1×9/100
= 6300/100
= $63
Therefore, the total amount she will receive at the end of a year = 700 + 63
= $763

The ratio of the length of candle A to the length of candle B at first will be 3 / 5.
What are ratios and proportions?A ratio is an ordered set of integers a and b expressed as a/b, with b never equaling 0. A proportional is a mathematical expression in which two things are equal.
Candle A and candle B were lit at the same time. candle a could last 3 hours and candle b could last 5 hours. after 1 hour, both candles were equal in length.
Then the ratio of the length of the candle A to the length of candle B at first will be
Let the length of candle A is x and the length of candle B be y.
The common speed will be S.
Then we have
Time = length / speed
For candle A, we have
Candle A = x / S = 3 ...1
For candle B, we have
Candle B = y / S = 5 ...2
From equations 1 and 2, we have
x / 3 = y / 5
x / y = 3 / 5

The statements about the design that are true are:
each sprinkler head is placed more than 3 feet from the walkwaythe total area watered by each sprinkler is approximately 63.6 square feet. the total area watered by all the sprinklers is approximately 254 square feet.How to explain the design?As we can see the distance from the sprinklers head to the walkway is more than one grid and length of one grid is 3 feet, so each sprinkler is placed more than 3 feet from the walkaway.
The radius of the area watered by each sprinkler = 1.5 grid = 1.5×3 = 4.5 feet. So area watered by each sprinkler = π×r² = (3.14)(4.5)² = 63.58 ≈ 63.6 feet². Area watered by one sprinkler = 63.6 feet², therefore total area covered by four sprinklers = 4×63.6 = 254 feet²

The proportion of all US adults who eat popcorn when they go to the movie theater is p = 0.87. A random sample of 20 US adults was selected and asked if they eat popcorn when they go to the movie theater. Which of the following is the shape of the sampling distribution of p hat ?
The sampling distribution of p hat is approximately Normal because n p = 17.4 greater-than 10.
Because n (1 minus p) = 20 (1 minus 0.87) = 2.6 less-than 10, the sampling distribution of p hat is not approximately Normal. The sampling distribution of p hat is skewed right and centered at 0.87.
Because n (1 minus p) = 20 (1 minus 0.87) = 2.6 less-than 10 , the sampling distribution of p hat is not approximately Normal. Because p = 0.87 is closer to 1 than 0, the sampling distribution of p hat is skewed to the left.
Because n (1 minus p) = 20 (1 minus 0.87) = 2.6 less-than 10, the sampling distribution of p hat is not approximately Normal. Because p = 0.87 is closer to 1 than 0, the sampling distribution of p hat is skewed to the right.
The option third is correct because nx(1-p)=2.6 less than equal to 10 then the sampling distribution [tex]\rm \hat{p}[/tex] is not approximate normal because p=0.87 is closer to 1 than zero.
Sampling distribution [tex]\rm \hat{p}[/tex] is skewed to the left.
What is a normal distribution?It's the probability curve of a continuous distribution that's most likely symmetric around the mean. On the Z curve, at Z=0, the chance is 50-50. A bell-shaped curve is another name for it.
Because the requirement for normal is greater than 10, n×p is greater than 10 and nx(1-p) is also greater than 10.
This situation is abnormal because it is not valid. If p is close to 1 in a normal graph, then p is left skewed.
Thus, the option third is correct because nx(1-p)=2.6 less than equal to 10 then the sampling distribution [tex]\rm \hat{p}[/tex] is not approximate normal because p=0.87 is closer to 1 than zero. Sampling distribution [tex]\rm \hat{p}[/tex] is skewed to the left.

A spinner has 4 equally sized sectors that are numbered 3, 3, 4 and 6. The spinner is spun twice and the sum of the outcomes is found.
A fair decision is to be made about which one of 4 vacation destinations will be planned, using the sum of the outcomes.
The vacation destination options are New Mexico, Alaska, Puerto Rico and London.
Which description accurately explains how a fair decision can be made in this situation?
If the sum is 6, the vacation destination will be London. If the sum is 8, the vacation destination will be Alaska. If the sum is 9, the vacation destination will be New Mexico. If the sum is 7, 10 or 12, the vacation destination will be Puerto Rico.
If the sum is 6, the vacation destination will be London. If the sum is 7, the vacation destination will be Alaska. If the sum is 10, the vacation destination will be New Mexico. If the sum is 8, 9 or 12, the vacation destination will be Puerto Rico.
If the sum is 6, the vacation destination will be London. If the sum is 7, the vacation destination will be Alaska. If the sum is 9, the vacation destination will be New Mexico. If the sum is 8, 10 or 12, the vacation destination will be Puerto Rico.
If the sum is 10, the vacation destination will be London. If the sum is 7, the vacation destination will be Alaska. If the sum is 9, the vacation destination will be New Mexico. If the sum is 6, 8 or 12, the vacation destination will be Puerto Rico.
Answer:
If the sum is 6, the vacation destination will be London.
If the sum is 7, the vacation destination will be Alaska.
If the sum is 9, the vacation destination will be New Mexico.
If the sum is 8, 10 or 12, the vacation destination will be Puerto Rico.
Step-by-step explanation:
Create a sample space for the 2 spins (see attached).
From the sample space, the probabilities are:
P(sum is 6) = 4/16P(sum is 7) = 4/16P(sum is 8) = 1/16P(sum is 9) = 4/16P(sum is 10) = 2/16P(sum is 12) = 1/16Therefore, to make a fair decision:
As the sum of 6, 7 and 9 each have equal probabilities (4/16), they should each be attritbuted to one destination.
As the sum of 8, 10 and 12 combined equal the same probability as the sum of 6, 7, and 9 individually, the sum of 8, 10 and 12 should be assigned to one destination combined.
Solution
If the sum is 6, the vacation destination will be London.
If the sum is 7, the vacation destination will be Alaska.
If the sum is 9, the vacation destination will be New Mexico.
If the sum is 8, 10 or 12, the vacation destination will be Puerto Rico.

how to find a length with perimeter 400cm and breadth 50cm.
Step-by-step explanation:
Asuming object is a rectangle. We know that to find the perimeter of a rectangle we must add all the sides.
Therefore the formula wound be "b + b + l + l". To simplify this equation we can goup the similar sides as "2b + 2l".
Since we know the perimeter of the rectangle lets equate this simplified formula to 400:
2b + 2l = 400
Now because we know the breath lets replace it with the b position in tge formula.
2(50) + 2l = 400
Now lets use simple algebra to solve.
100 + 2l = 400
2l = 400 - 100
2l = 300
l = 150
Therefore, the lenght is 150cm
