Answer 1

Answer:

The probability of chosen student choosing apple wedges and he is from high school is 9% so option (A) is correct.

What is probability?

The probability of an event occurring is defined by probability.

Probability is also called the chance because if you flip a coin then the probability of coming head and tail is nothing but chances that either head will appear or not.

Do not take underestimate probability it has several uses in daily life whether forecasts or like that.

In our daily time, there are several instances in the everyday world where we may need to draw conclusions about how everything will turn out.

Probability of choosing apple wedges and he is from high school ⇒

P(Apple wedge and high school) = P(Apple wedge) × P(high school/apple wedge)

Now,

Probability = desired/total

So,

P(Apple wedge) = 90/400

Now,

P(high school/apple wedge) = 36/90

So,

P(Apple wedge and high school) = (90/400) × (36/90)

P(Apple wedge and high school) = 0.09 ⇒ 9%

Hence "The probability of chosen student choosing apple wedges and he is from high school is 9%".

PLEASE HELP The table below represents the distance of a car from its destination as a function of time.

Time
(hour)
x
Distance (miles)
y
0
900
1
850
2
800
3
750

Part A: What is the y-intercept of the function and what does this tell you about the car? (4 points)

Part B: Calculate the average rate of change of the function represented by the table between x = 1 to x = 3 and what does the average rate represent? (4 points)

Part C: What would be the domain of this function if the car traveled the same rate until it reached its destination? (2 points)

Answers

First we have to determine a linear equation. We will take two points (0,900) and (1,850):
y=mx+b
900=m*0+b, b=900
850=m*1+900
m=-50
Linear equation is:
y=-50x+900
Part A: y-interception is y=900 or(0,900).
It means that a car has to travel a distance of 900 miles to reach a final destination.
Part B:Average rate of change: $(y2-y1)/(x2-x1) = (750-850)/(3-1)= (-100)/(2)$ =-50. It represents how many miles per one hour changes the distance from a destination.
Part C: Domain of this function if the car traveled the same rate until it reached its destination:
0=-50x+900
50x=900
x=900/50=18
Domain: x∈ [0, 18].

Answer:

Step-by-step explanation:

First we have to determine a linear equation. We will take two points (0,900) and (1,850):

y=mx+b

900=m*0+b, b=900

850=m*1+900

m=-50

Linear equation is:

y=-50x+900

Part A: y-interception is y=900 or(0,900).

It means that a car has to travel a distance of 900 miles to reach a final destination.

Part B:Average rate of change:=-50. It represents how many miles per one hour changes the distance from a destination.

Part C: Domain of this function if the car traveled the same rate until it reached its destination:

0=-50x+900

50x=900

x=900/50=18

Domain: x∈ [0, 18
