The probability that a person could not give up cell phone but could give up television can be expressed as the probability of No could give up cell phone and Yes could give up television, P(NnY) = 0.39
<u>From the two way probability table given</u> :
- Let, probability that a person could not give up cell phone = N
- Probability that a person could give up television = Y
The intersection of Y and N = P(Y n N)
- The probability value at the intersection point using the table given ls 0.39
Therefore, the probability of YnN is 0.39

The percentage would be 75% that carpenters that showed up for work
because when dividing 200 x 4 you will get 50 and 50 would equal to 25% of the total of carpenters and if you multiply 50 by 3 would get 150 and a percentage wise that would be 25% times three which is 75 and that’s how you get the answer
Answer:a valid solution is (1,3)
Explanation:First, let' simplify the given equation:
14mn = 55 - 7m - 2n
14mn + 2n = 55 - 7m - 2n + 2n
n (14m + 2) = 55 - 7m
n =
![\frac{55-7m}{14m+2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B55-7m%7D%7B14m%2B2%7D%20)
Now, we have only one equation in two unknowns. Therefore, the only way to solve this is by assuming one of the variables and solving for the other taking into consideration that both should be positive integers.
1- Assume m = 2:
n =
![\frac{55-7(2)}{14(2)+2} = \frac{41}{30}](https://tex.z-dn.net/?f=%20%5Cfrac%7B55-7%282%29%7D%7B14%282%29%2B2%7D%20%3D%20%20%5Cfrac%7B41%7D%7B30%7D%20)
.....> n is not a positive integer .........> This assumption is rejected
2- Assume m = 1:
n =
![\frac{55-7(1)}{14(1)+2} = 3](https://tex.z-dn.net/?f=%20%5Cfrac%7B55-7%281%29%7D%7B14%281%29%2B2%7D%20%3D%203)
.......> both m and n are positive integers ........> This assumption is accepted ...........> Therefore, the solution would be (1,3)

Answer:
Null Hypothesis: ![H_0:\mu=171](https://tex.z-dn.net/?f=H_0%3A%5Cmu%3D171)
Alternative Hypothesis: ![H_1:\mu\neq 171](https://tex.z-dn.net/?f=H_1%3A%5Cmu%5Cneq%20171)
Step-by-step explanation:
It is given that the mean height of a certain kind of plant is 171 centimeters.
Null Hypothesis: A hypotheses of no statistical significant difference is known as null hypothesis. The null hypotheses for this test is
![H_0:\mu=171](https://tex.z-dn.net/?f=H_0%3A%5Cmu%3D171)
Alternative Hypothesis: If a hypothesis is used in hypothesis testing that is contrary to the null hypothesis is known as alternative hypotheses. The alternative hypotheses for this test is
![H_1:\mu\neq 171](https://tex.z-dn.net/?f=H_1%3A%5Cmu%5Cneq%20171)
