examine the spinner at right. If the central angle of region A is 7 calculate the expected value of one spin.Round to the nearest hundredth..pls hurry
Answers
Answer:
The whole angle on a circle is equal to 360°.
This means that:
∠A + ∠B = 360°.
Here we know that ∠A = 7°
Then ∠B = 360° - 7° = 353°
Now, if the probability is evenly distributed for all the angles, then the probability that the spinner lands in A is equal to the quotient between the measure of the angle A, and the measure of the total circumference, this will be:
Pa = 7°/360° = 0.019
And the same for B:
Pb = 353°/360° = 0.981
Now, the expected value can be calculated as:
Ev = ∑xₙ*pₙ
Where xₙ is the event n, and pₙ is its probability.
Then:
x₁ = A = 100
p₁ = Pa = 0.019
x₂ = B = 2
p₂ = Pb = 0.981
The expected vale will be:
Ev = 100*0.019 + 2*0.981 = 3.862
Rounding to the nearest hundredth, the second digit after the decimal point, we have:
Ev = 3.86

Aubrey and Charlie are driving to a city that is 120 miles from their house. They have already traveled 20 miles, and they are driving at a constant rate of 50 mi/h. Part A Write the function that models their distance from home as a function of time. f(x) = x + Part B What is a reasonable domain for this situation? ≤ x ≤
Answers
y= 50x + 20
120 = 50(2) + 20
0 <(or equal to) x <(or equal to) 2
their distance from home as a function of time
[tex]f(x)=50x+20[/tex]
The reasonable domain for this situation is
[tex]0\leq x\leq 2[/tex]
Given :
Aubrey and Charlie are driving to a city that is 120 miles from their house. They have already traveled 20 miles, and they are driving at a constant rate of 50 mi/h.
Given driving speed is 50 miles per hour
They already travelled 20 miles. We need to frame linear equation because we are given with constant rate.
Linear equation is [tex]f(x)=mx+b[/tex]
where m is the constant rate and b is the initial miles travelled
m=50 and b=20
the function f(x) is the distance from home
[tex]f(x)= 50x+20[/tex]
Now we find out the domain x. Given that they travelled 120 miles
so f(x) is 120
[tex]120=50x+20\\120-20=50x\\100=5x\\x=2[/tex]
Domain is the number of hours travelled
hours cannot be negative . So the domain x for this situation is
[tex]0\leq x\leq 2[/tex]

At a candy store, you can buy pre-filled bags of candy that weigh 2 1/4 pounds for $8. At this same rate, how much would a 4 pound
bag of candy cost?
Answers
Answer:
$14.22Step-by-step explanation:
step one:
given data
we are told that 2 1/4( 2.25 pound) of candy cost $8
let us find the cost of 1 pound first
so
2.25 pound cost #8
1 pound will cost x
cross multiply
x=8/2.25
x=$3.55 for one pound.
step two:
Hence if 1 pound cost $3.55
4 pound will cost = 3.55*4= $14.22
A fair spinner has 9 equal sections: 3 red, 4 blue and 2 green. It is spun twice. What is the probability of getting not green then green?
Answers
I am given that p || q. ∠1 and ∠4 are supplementary angles because they form a linear pair, so m∠1 + m∠4 = 180°. ∠4 and ∠8 are also supplementary because of the Same-Side Interior Angles Postulate, so m∠4 + m∠8 = 180°. You can substitute m∠4 + m∠8 for 180° in the first equation above. The result is m∠1 + m∠4 = m∠4 + m∠8. After subtracting m∠4 from each side, I see that m∠1 = m∠8.

A teacher divided 60 stickers among 3 students in a ratio of 2:3:5. How many stickers did each student receive?
Answers
Answer:
12:18:30
Step-by-step explanation:
I do RSM too, have a good day :)
The number of stickers did each student receive get is 12, 18 and 30 respectively.
Given that, a teacher divided 60 stickers among 3 students in a ratio of 2:3:5.
What is the ratio?The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.
Here, 2+3+5=10
Number of stickers student 1 get
= 2/10 × 60
= 12
Number of stickers student 2 get
= 3/10 × 60
= 18
Number of stickers student 3 get
= 5/10 × 60
= 30
Therefore, the number of stickers did each student receive get is 12, 18 and 30 respectively.

Janet can do a job in 3 hours, and Garry can do the same job in 2 hours. If Janet works for 1 hour before Garry comes to help, how long will it take them to do it together.
Answers
Answer:
48 minutes
Step-by-step explanation:
Given that:
Time taken by Janet = 3 hours
Janet's rate = 1/3 job / hour
Time taken by Garry = 2 hours
Garry's rate = 1/2
Rate of working together :
1/3 + 1/2 = (2 + 3) /6 = 5/6 job/hour
If Janet works for one hour before Garry joins ;
1/3 of the job has been done by Janet
1 - 1/3 = 2/3 of the job left
Hence to finish the job together, it will take :
Fraction of JOB left ÷ rate of working together
(2/3 ÷ 5/6)
= 2 /3 * 6/5
= 12 / 15
= 4 / 5 hours

Equation parallel y= -3 also passes through the point (2,5)

Answer:
When somethins is parallel it never crosses each other, this means the new equation has to have the same slope but, since y=-3 is a straight line we just have to make the new line also a straight line, maknig sure it passes through (2,5).
To do this make y equal the y-coordinate of the points it needs to pass through. This would make the answer y=5

Answer:
x= -3
y= -2
From the first one, if you add 2y to both sides you can plug that into the second one and solve for y. Then, plug y to the first one and solve for x.
X=1+2y
2(1+2y)+3y=-12
2+4y+3y=-12
2+7y=-12
7y=-12-2
7y=-14
y=-2
