An elementary school bus comes at 8:15 am every morning to pick up children in a neighborhood. The probability that the bus will be late is 0.19 and the probability that the bus will be early is 0.02.
What is the probability that the bus will arrive early next two days?
What is the probability that the bus will arrive on time next two days?
In two or more complete sentences, explain your calculations for parts A and B. In your explanation, include their similarities and differences.

Answers

Answer:

a. .02 * .02 = .0004  

b. (1 - .02 - .19) = .79; .79*.79 = .6241

Step-by-step explanation:

The probability that the bus will arrive on time next two days is 0.79, The probability that the bus will arrive early next two days is 0.0004.

What is Probability?

Probability is the likeliness of an event to happen, it has a range from 0 to 1.

Probability that the bus will be late is 0.19

Probability that the bus will be early is 0.02.

The probability that the bus will arrive early next two days is

= 0.02 * 0.02

=0.0004

The probability of coming early one day is small and the probability that it will come early two days in a row is smaller.

The probability that the bus will arrive on time next two days

= (1 - 0.02 -0.19) = 0.79

The probability that the bus will come on time is more as the probability of coming early or late is less.

jim can paint 5 chairs with 11.3 gallons of paint how many chairs can he paint with 24.86 gallons​

Answers

Jim can paint 11 chairs. if 5 chairs is 11.3 then 10 chairs are 22.6 and if you want to know how much is on 24.86 you divide 11.3 with 5 because then you can add with 1 chair at a time which is 2.26 and then you add 2.26 which is exactly 24.86. 5+5+1 is 12.


5 chairs=11.3
10 chairs=22.6

Answers

Answer:

a = 49°

Step-by-step explanation:

From the figure attached,

In ΔBOC,

OB = OC = Radii of the circle O

Therefore, m∠OBC = m∠OCB = 41° [Opposite angles of the equal sides of a triangle]

By triangle sum theorem,

m∠OBC + m∠OCB + m∠BOC = 180°

41° + 41° + m∠BOC = 180°

m∠BOC = 180° - 82°

              = 98°

Since, "angle subtended by an arc at the center is twice the angle subtended at the circumference",

m∠BOC = 2(m∠BAC)

98° = 2(a)

a = 49°

Point M is between points L and N on LN. LN
6x, LM 4x + 8, and
MN 27. Use the information to solve for x, and then find LN.

Answers

Answer:

Step-by-step explanation:

     4x+8                  27

L-------------M-------------------------N

<------------------ 6x -------------------->

LM = 4x+8

MN = 27

LN = 6x

LM + MN = LN

4x+8 + 27 = 6x

35 = 2x

17.5 = x

LN = 6x = 6(17.5) = 105

The correct answer to the question is: x = 17.5, LN = 105

From the question given above, we obtained the following:

LN = 6x

LM = 4x + 8

MN = 27

x =? LN =?

The value of x can be obtained as follow:

LN =  LM + MN

6x = 4x + 8 + 27

6x = 4x + 35

Collect like terms

6x – 4x = 35

2x = 35

Divide both side by 2

x = 35 / 2

x = 17.5

Finally, we shall determine the value of LN.

x = 17.5

LN =?

LN = 6x

LN = 6(17.5)

LN = 105

SUMMARY:x = 17.5LN = 105

Therefore, the correct answer to the question is: x = 17.5, LN = 105
