An employee works 22 days per month. if they work an average of 8 1/4 hours per day how many hours do they work per month?

Schach [20]

Answer:

181 $\frac{1}{2}$

Step-by-step explanation:

To find how many hours they work per month multiply the amount of hours they work each day by the amount of days they work in a month:

$22 *8\frac{1}{4} = 181\frac{1}{2}$

They work $181\frac{1}{2}$ hours per month.

Hope this helps :)

The following lists the joint probabilities associated with smoking and lung disease among 60-to-65 year-old men. Has Lung Disea

Anna71 [15]

Answer:

4.11% probability that he has lung disease given that he does not smoke

Step-by-step explanation:

We use the conditional probability formula to solve this question. It is

$P(B|A) = \frac{P(A \cap B)}{P(A)}$

In which

P(B|A) is the probability of event B happening, given that A happened.

$P(A \cap B)$ is the probability of both A and B happening.

P(A) is the probability of A happening.

In this question:

Event A: Does not smoke

Event B: Lung disease

Lung Disease/Nonsmoker 0.03

This means that $P(A \cap B) = 0.03$

Lung Disease/Nonsmoker 0.03

No Lung Disease/Nonsmoker 0.7

This means that $P(A) = 0.03 + 0.7 = 0.73$

What is the probability of the following event: He has lung disease given that he does not smoke?

$P(B|A) = \frac{0.03}{0.73} = 0.0411$

4.11% probability that he has lung disease given that he does not smoke

In ΔLMN, \overline{LN} LN is extended through point N to point O, m∠NLM = (x+1)^{\circ}(x+1) ∘ , m∠LMN = (x+15)^{\circ}(x+15) ∘

mixer [17]

Answer:

26 degree

Step-by-step explanation:

We are given that in triangle

$\angle NLM=(x+1)^{\circ}$

$\angke LMN=(x+15)^{\circ}$

$\angle MNO=(4x+6)^{\circ}$

$\angle MNO+\angle MNL=180^{\circ}$

By using linear pair angles property

$\angle MNL=180-\angle MNO=180-(4x+6)$

$\angle MNL+\angle NLM+\angle LMN=180^{\circ}$

By using triangle angles sum property

$180-(4x+6)+x+15+x+1=180$

$2x+16=180-180+4x+6$

$16-6=4x-2x=2x$

$2x=10$

$x=\frac{10}{2}=5$

Substitute the value

$\angle MNO=4(5)+6=20+6=26^{\circ}$
