Step-by-step explanation:

1075 students were asked how close they live to the college. The table shows the results below with some values missing. Enter the correct values in the boxes remembering to use the % symbol where necessary.

20 to 25: given 20%

20% of 1,075 = 215

15 to 19: given 12%

12% of 1,075 = 129

10 to 14: given 516 students

(516/1,075)*100 = 48%

5 to 9: given 162 students

(162/1,075)*100 = 15.07%

< 5: given 53 students

(53/1,075)*100 = 4.93%

= 21.825

triangle
A = 0.5(2.7)4.5
= 6.075

rectangle
A = 1.8(4.5)
= 8.1

Total Area = 21.825 + 6.075 + 8.1

In an experiment, a ball is drawn from an urn containing 12 purple balls and 13 green balls. If the ball is purple, two coins ar

UNO [17]

Answer:

4 elements of the sample space will have a purple ball

There are 10 elements altogether

Step-by-step explanation:

Probability is given by number of possible outcomes ÷ number of total outcomes

Number of purple balls = 12, number of green balls = 13, total number of balls = 12+13 = 25

Probability (a ball drawn is purple) = 12/25

If a purple ball is drawn, two coins are tossed

1 coin has 2 elements

2 coins have 2×2 = 4 elements

Probability (a ball drawn is not purple) = 1 - 12/25 = (25-12)/25 = 13/25

If a ball drawn is not purple, three coins are tossed

1 coin has 2 elements

3 coins have 3×2 = 6 elements

Total elements = 4 + 6= 10 elements

Solve for x 20 points

torisob [31]

Answer:

x = 21 units

Step-by-step explanation:

The tangent squared is equal to the secant's total length multiplied by the secant's length without the part inside the circle.

So here, that will look like: 36² = 27 * (27 + x)

Expansion and multiplication gives us: 1296 = 729 + 27x

Subtract from both sides: 567 = 27x

Divide from both sides: x = 21.
