Kimberly is a program director for the channel KID. She tracked the cartoons shown on the channel for a week. The probability that the show had animals in it was 0.7. The probability that the show aired more than 10 times was 0.4. The probability that the show had animals in it and aired more than 10 times was 0.2. Which equation shows the correct use of the addition rule to determine the probability that a randomly selected show had animals in it or aired more than 10 times?
Answers
Options
- 0.7+0.2−0.4=0.5
- 0.7+0.2=0.9
- 0.7+0.4=1.1
- 0.4+0.2=0.6
- 0.7+0.4−0.2=0.9
Answer:
Step-by-step explanation:
In probability theory
Let the event that the show had animals in it = A
P(A)=0.7
Let the event that the show aired more than 10 times =B
P(B)=0.4
P(A and B)= 0.2
Therefore, the equation which shows the correct use of the addition rule to determine the probability that a randomly selected show had animals in it or aired more than 10 times is:
The correct option is E.

What’s the LCD Of 5/8
In tilapia, an important freshwater food fish from Africa, the males actively court females. They have more incentive to court a female who has already laid all of her eggs, but can they tell the difference? an experiment was done to measure the male tilapia's response to the smell of female fish. Water containing feces from females that were either pre-ovulatory (they still had eggs) or post-ovulatory (they had already laid their eggs) was washed over the gills of males hooked up to an electro-olfactogram machine which measured when the senses of the males were excited. The amplitude of the electro-olfactogram was used as a measure of the excitability of the males in the two different circumstances. Six males were exposed to the scent of pre-ovulatory females; their readings average 1.51 with a standard deviation of .25. Six different males were exposed to post-ovulatory females; their average readings of 0.87 with standard deviation is .31. Assume that the electro-olfactogram readings were approximately normally distributed within the groups.(A) test for a difference in the excitability of the males with exposure to these two types of females(B) what is the estimated average difference in electro-olfactogram readings between the two groups? What is the 95% confidnece limit for the difference between population means?
a. 1.275
b. 8
c. 10.2
d. 10.24

Answer:
1.275
Explanation:
The given equation is:
f(x) = 0.01(2)ˣ
We want to find the rate of change from 2 to 10 which means that we need to find the slope from 2 to 10.
We start by getting the y-values for each of the given x-values:
at x = 2 ..........> y = 0.01(2)² = 0.04 ...........> point is (2, 0.04)
at x = 10 .........> y = 0.01(2)¹⁰ = 10.24 .........> point is (10, 10.24)
Now, we get the slope as follows:
slope =
Hope this helps :)
Answer: a. 1.275
Step-by-step explanation:
Let f(x) be any function.
Then the average rate of change from x= a to x= b is given by :-
The given function :
Then, the average rate of change from x = 2 to x = 10 will be :-
Hence, the average rate of change from x = 2 to x = 10 is 1.275.

Answer:
There are 9,000,000 seven-digit positive integers.
Explanation:
For the first digit, we have 9 choices: 1, 2, 3, 4, 5, 6, 7, 8, 9.
For each remaining digit, we have 10 choices: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9.
Each choice is independent of the others. So, the number of total 7-digit positive integers is the product of all the numbers of choices for each digit.

Since 0 cannot be put as the first digit, there are 9 choices for the first digit, and the next 6 digits have 10 choices. So, there are 9 × 10^6 = 9000,000 numbers.
