Answer:
x ≈ 18.9
Step-by-step explanation:
using the cosine ratio in the right triangle
cos19° = =
( multiply both sides by 20 )
20 × cos19° = x , then
x ≈ 18.9 ( to the nearest tenth )

Answer:
56 as a product of primes using index notation is:
Step-by-step explanation:
We need to write 56 as a product of primes.
Prime Numbers:
<em>Numbers that are divisible by 1 or itself.</em>
Now, writing 56 as product of primes
56 = 2 x 2 x 2 x 7
Now, Use index notation when giving your answer.
Index Notation:
<em>Express elements in power form i.e. if we have 2 x 2 we can write it as 2^2</em>
So, answer will be:
So, 56 as a product of primes using index notation is:
Answer:
1. The required information are
The average annual bonuses, received by employees from company A
The average annual bonuses, received by employees from company B
The standard deviation, σ₁, of the average annual bonuses for employees from company A
The standard deviation, σ₂, of the average annual bonuses for employees from company A
The number of employees in company A, n₁
The number of employees in company B, n₂
2. The null hypothesis is H₀: -
≤ 100
The alternative hypothesis is Hₐ: -
> 100
Step-by-step explanation:
1. The required information are
The average annual bonuses, received by employees from company A
The average annual bonuses, received by employees from company B
The standard deviation, σ₁, of the average annual bonuses for employees from company A
The standard deviation, σ₂, of the average annual bonuses for employees from company A
The number of employees in company A, n₁
The number of employees in company B, n₂
2. The null hypothesis is H₀: -
≤ 100
The alternative hypothesis is Hₐ: -
> 100
The z value for the hypothesis testing of the difference between two means is given as follows;
At 0.5 level of significance, the critical = ± 0
The rejection region is z > and z < -
Therefore, the value of z obtained from the relation above more than or less than 0, we reject the null hypothesis, and we fail to reject the alternative hypothesis.
