Answer: Probability that they will both occur is 25%.

Step-by-step explanation:

Since we have given that

There are two non simultaneous events.

Probability of each event = 50%

Since both are independent to each other.

Let A and B be two events.

We need to find the probability that they will both occur i..e P(A∩B).

As we know the rule of independence of events:

P(A\cap B)=P(A).P(B)\\\\P(A\cap B)=0.5\times 0.5\\\\P(A\cap B)=0.25\\\\P(A\cap B)=25\%\\

Hence, Probability that they will both occur is 25%.

80% of x is equal to 100.<br><br> Find x.
xeze [42]

The number is 125 and the equation is 0.8x = 100

Step-by-step explanation:

80% of x is equal to 100.

Write an equation that shows the relationship of 80%, x, and 100

80% = 0.8

0.8x = 100

x = 100/0.8

x = 125

The number is 125 and the equation is 0.8x = 100

Fynjy0 [20]

Answer:

2x-3y=2

x=6y-5

2(6y-5)-3y=2

use the distributive property.

2*6y=12y

2*-5=-10

12y-10-3y=2

combine like terms

12y-3y=9y

9y-10=2

add 10 to both sides.

9y-10+10=9y

2+10=12

9y=12

divide both sides by 9

9y/9=y

y=about 1.33

plug in the value of y in the expression equal to the value of x.

x=6(1.33)-5

solve

6*1.33=7.98

x=7.98-5

7.98-5=2.98

Step-by-step explanation:

x=2.98

y=1.33

A middle school has an oval track with the dimensions shown. What is the distance around the track? use 3.14 for π. show your wo
Snezhnost [94]

Answer:

10859.94

Step-by-step explanation:

To solve this, you need to know the formula for solving the area of a circle: πr²

The first thing you should do is find the area of the square: 78 x 78 = 6084

Then, we find the area of the circle. To do this, we must figure out the radius. Luckily, the problem states that the combined diameter of both half circles is 78, which means the radius is 39. Then, we can apply the formula: π39².

39² = 1521

1521 x 3.14 = 4775.94

This is the combined area of both half circles.

Finally, we have to add: 4775.94 + 6084 = 10859.94
