The total number of photos on Hannah's camera is a linear
2 answers:
Answer:
The linear function is y = 44 + 24x
The rate of change of the linear function is 44.
Step-by-step explanation:
Hannah already had 44 photos in her camera so this is the initial value of the linear function.
She took 24 photos each day for 6 days. Which means she took:
24 x 6 = 144 photos in those 6 days.
We multiplied 24 with the number of days she took the photos so, considering 'x' as the number of days we can write '24x' to represent the number of photos she took. the linear function can be represented as:
y = 44 + 24x
To find out the rate of change, we need to differentiate this equation. So,
The rate of change of the linear function is 44.

Answer:
<u>0.9524</u>
Step-by-step explanation:
<em>Note enough information is given in this problem. I will do a similar problem like this. The problem is:</em>
<em>The Probability of a train arriving on time and leaving on time is 0.8.The probability of the same train arriving on time is 0.84. The probability of the same train leaving on time is 0.86.Given the train arrived on time, what is the probability it will leave on time?</em>
<em />
<u>Solution:</u>
This is conditional probability.
Given:
- Probability train arrive on time and leave on time = 0.8
- Probability train arrive on time = 0.84
- Probability train leave on time = 0.86
Now, according to conditional probability formula, we can write:
= P(arrive ∩ leave) / P(arrive)
Arrive ∩ leave means probability of arriving AND leaving on time, that is given as "0.8"
and
P(arrive) means probability arriving on time given as 0.84, so:
0.8/0.84 = <u>0.9524</u>
<u></u>
<u>This is the answer.</u>
