Answer: B, C, AND A
Step-by-step explanation:
<u>Answer:
</u>
The standard form of is 20,00,0000
<u>Solution:
</u>
Given that ---- eqn 1
To write in standard form,
We know that .So becomes .
Now eqn 1 becomes,
----- eqn 2
We know that , so
Now eqn 2 becomes,
---- eqn 3
Expanding :
Here 10 is the base term and 7 is the exponent value. So base term 10 is multiplied by itself 7 times.
Now eqn 3 becomes,
= 20,00,0000
Hence the standard form of is 20,00,0000
Step-by-step explanation:
consider k the numbe of correct answers
P(k) = kC8×(0,2)^k×(0,8)^(8-k)
example:
The probability of having 2 correct answers = 2C8×(0,2)^2×(0,8)^(6) = 0.294
the probability that the number x or correct answer is fewer than 4 =
p(0) + p(1) + p(2) + p(3) = 0.944
Answer: x = 29
Step-by-step explanation:
The four angles of a Parallelogram equal to 360. Its name is derived from the fact that its made up of two sets of parallel lines which means that its opposite angles are equivalent. Fortunately, you are given the values for the angles that are not equivalent which means you can create an equation and solve for x.
5x - 23 + 5x - 23 + 2x + 2x = 360
14x - 46 = 360
14x = 406
x = 29
Answer:
The probability of randomly select an adult that has between 18 and 29 years old and use social media is 22.3%
Step-by-step explanation:
As the test is targeted to 18-to-29-year-old adults using social media, we want to know the probability that a randomly selected adult uses social media and belong to the study group.
To achieve this, we have this data:
- 36% of all adults do not use social media
- 75% of all adults are >30 years old.
- The percentage of population that is <em>either</em> 18-29 years old <em>or</em> uses social media is 66.7%
Using the last data we have that
The probability of randomly select an adult that has between 18 and 29 years old and use social media is 22.3%
