Find the value of X

Mathematics
1 answer:
kap26 [50]2 years ago
7 0

Answer:

x = 27

Step-by-step explanation:

We can say that sum of all interior angles adds up to: 180°, therefore;

(3x - 17) + (2x - 5) + (x + 40) = 180°

=> now add like terms together:

=> 3x + 2x + x = 6x

=> -17 + (-5) + 40 = 18

Therefore;

6x + 18 = 180°

6x = 180 - 18

6x = 162

x = 162/6

<u>x = 27</u>

Hope this helps!

What is the probability that in a randomly selected game, the first goal is scored in less than 4 minutes?
kogti [31]

Based on the characteristics of the distribution, the probability that the first goal is scored in less than 4 minutes is 0.

<h3>What is the probability?</h3>

For us to be able to calculate the probability that the first goal is scored in less than 4 minutes, the distribution needs to satisfy the requirements of the Central Limit Theorem(CLT).

Based on the fact that the distribution here is extremely right skewed, then it does not satisfy the requirements of CLT so the probability is 0.

First part of question:

The distribution of the time it takes for the first goal to be scored in a hockey game is known to be extremely right skewed with population mean 12 minutes and population standard deviation 8 minutes.

astra-53 [7]

Answer: C.186


Step-by-step explanation:

1. You know that he read 6 books when he was 6 years old and every year he doubled the number of books he read the previous year.

2. Let's call n the number of book he read each year and n_t the number of books he read between the ages of 6 and 10, then:

 - At 6 years old:

n=6

- At 7 years old:

n=6*2=12

- At 8 years old:

n=12*2=24

- At 9 years old:

n=24*2=48

- At 10 years old:

n=96

The total books he read between the ages of 6 and 10 is:

n_t=6+12+24+48+96\\n_t=186
