At a certain middle school, there are 200 5th graders, 220 6th graders, 180 7th graders, and 150 8th graders. The Dean of Students chooses a scholar at random to help run Community Circle. What is the probability that a 7th grader is chosen?
Answer:
6/25
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.
probability that a 7th grader is chosen = total number of 7th graders / total number of students
total number of 7th graders = 180
total number of students = 200 + 220 + 180 + 150 = 750
180 / 750
To transform to the simplest form. divide both the numerator and the denominator by 30
6 / 25
Trig homework. Find the two missing sides and write your answer as in simplified radical form.
Answer:
u = 8, v = 4[tex]\sqrt{2}[/tex]
Step-by-step explanation:
Using the sine ratio in the right triangle and the exact value
sin45° = [tex]\frac{1}{\sqrt{2} }[/tex] , then
sin45° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{4\sqrt{2} }{u}[/tex] = [tex]\frac{1}{\sqrt{2} }[/tex] ( cross- multiply )
u = 8
The triangle is right isosceles with legs congruent, so
v = 4[tex]\sqrt{2}[/tex]

Use the rectangle FOUR to find the value of x.
in FU = 38, RQ = 2x + 9.
Answer:
x = 5
Explanation:
2x + 9 = 19
2x = 10
x = 5
Applying the properties of the diagonal of a rectangle, the value of x is determined as: 5.
Diagonals of a RectangleThe diagonals of a rectangle are of equal length.The diagonals of a rectangle bisects each other into two equal halves.FU and RO are diagonals of rectangle FOUR.Therefore:
2(RQ) = FU
Substitute
2(2x + 9) = 38
4x + 18 = 38
4x = 38 - 18
4x = 20
x = 5
Thus, applying the properties of the diagonal of a rectangle, the value of x is determined as: 5.

Aretha's teacher will choose two students from a class of 10 to prepare a display. Assuming the teacher chooses these students at random,
what is the probability that Aretha will not be chosen?
Answer:
80% chance she will not be chosen
Step-by-step explanation:
the ratio of students picked would be 2:10 so there would be 8:10 students not chosen that is 80%. 20% chance she would be chosen.
I hope this is correct!
The probability that Aretha will not be chosen is 0.8.
What is the probability?Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.
Given that, Aretha's teacher will choose two students from a class of 10 to prepare a display.
We know that, probability of an event = Number of favourable outcomes/Total number of outcomes
Probability of choosing 2students =2/10
Probability of not choosing students = 1-2/10
= 8/10
= 0.8
Therefore, the probability that Aretha will not be chosen is 0.8.

39 divided by 60 is 65 percent .
Answer:
Phil did better on his History test.
Step-by-step explanation:
In the history test, he scored a 28/40. There are many ways to do this, but here is my way. Convert this to decimal to make comparison easy.
28/40 = 0.7
In the Geography test, he scored 39/60. Convert this to decimal as well.
39/60 = 0.65.
Since 0.7 > 0.65, Phil did better on his history test.

PLEASE HELP ASAP ILL GIEV BRAINLIEST
Answer:
D. 8 times
Step-by-step explanation:
lmk if its right bc im not too confident </33
D. The new volume will be 8 times the original volume.
The measurements of the rectangular prism are 5m ( length ), 3m ( width ), and 2m ( height ). To find the volume of the rectangular prism, you have to multiply the length, width, and height altogether. That gives you ( 5*3*2= ) 30 cubic meters. However, if the measurements were doubled for each edge, the new measurements would be ( 5*2= ) 10m ( new length ), ( 3*2= ) 6m ( new width ), and ( 2*2= ) 4m ( new height ). Multiplying those new measurements together would get you the volume of ( 10*6*4= ) 240 cubic meters. Now, in order to find out how it affects the volume of the prism, you divide 240 cubic meters by 30 cubic meters and get 8. Therefore, the answer will be D. The new volume will be 8 times the original volume.

Arthur's brother wants to borrow some money. Arthur decided to lend him $1000 at 2% simple interest. If the loan will cost his brother $50, how much time does he have before he has to pay Arthur back. (See Example 2 in your notes.)
a
2 years
b
2.5 years
c
3 years
d
3.5 years
Answer:
2.5
Step-by-step explanation:
Answer: b. 2.5 years
Step-by-step explanation:
The formula for Interest is:
= principal × rate × time
Then, we slot in the values given which will be:
Interest = principal × rate × time
50 = 1000 × 2% × Time
50 = 1000 × 0.02 × Time
50 = 20 × Time
Time = 50/20
Time = 2.5 years

Fred purchased a cone filled with cinnamon pieces. The cone is 7 inches tall and has a diameter of 2. How many cubic inches does the cone hold? Leave your answer in terms of pi
Answer:
V = 9.33 π m³
Step-by-step explanation:
Given: The cone is 7 inches tall and has a diameter of 2
To find: How many cubic inches the cone can hold
Formula: The formula for the volume of a cone is V = [tex]\frac{1}{3} h\pi r[/tex]².
Solution: A cone is a solid that has a circular base and a single vertex. To calculate its volume you need to multiply the base area
(area of a circle: π × r²) by height and by [tex]\frac{1}{3}[/tex]:
volume = ([tex]\frac{1}{3}[/tex]) × π × r² × h.
In terms of pi V = 9.33 π m³

The main diagonal of any cube can be found by multiplying the length of one side by the square root of 3.
Given: side x = 3 cm
Use the diagonal formula,
Diagonal of cube = 3–√x
Diagonal of cube = 3–√ × 3
We know that the value of √3 is 1.734
Therefore, the diagonal of a cube = 1.734 (3)
Diagonal of cube = 5.20 cm

(suggested by my sister plz help her ty)
Answer:
The answer is letter A and letter F.
Step-by-step explanation:
The question is asking if any of these choices are less than 300 centimeters. To find this out, first, you have to convert the meters to centimeters, to make it easier. (1 centimeter is equal to 0.01 meters) Multiply the meters by 100. For example 1.8m x 100 = 180cm. Do the rest for the other meters and then add them to the centimeters. Example: 180cm + 110cm = 290cm, which is less than 300cm.
