Answer:

OX = 7 1/11

Step-by-step explanation:

m∠BOX = 90 - m∠BOL

m∠POD = 90 - m∠POL

m∠BOL = m∠POL

m∠BOX = m∠POD

m∠XBO = m∠DPO

ΔBXO similar to ΔPDO

12/10 = OX / (13 - OX)

10 * OX = 12 * 13 - 12 * OX ... add 12 * OX both sides

22 * OX = 156

OX = 7 1/11

Nike reported a profit of $28,951,000 for one quarter (3 months), a profit of $20,570,000 for the second quarter, a profit of $1

Olenka [21]

Answer:

$\$16,826,000$ .

Step-by-step explanation:

We have been given that Nike reported a profit of $28,951,000 for one quarter (3 months), a profit of $20,570,000 for the second quarter, a profit of $15,342,000 the third quarter, and a loss of $48,037,000 for the fourth quarter.

To find the net profit for year, we will subtract the loss in the 4th quarter from the sum of profit in 3 quarters as:

$\text{Net profit for the year}=\$28,951,000+\$20,570,000+\$15,342,000-\$48,037,000$

$\text{Net profit for the year}=\$64,863,000-\$48,037,000$

$\text{Net profit for the year}=\$16,826,000$

Therefore, the net profit for the year was $\$16,826,000$ .

The average time a subscriber spends reading The Wall Street Journal is 49 minutes (The Wall Street Journal Subscriber Study). A

erica [24]

Answer:

$P(X>60)=P(\frac{X-\mu}{\sigma}>\frac{60-\mu}{\sigma})=P(Z>\frac{60-49}{16})=P(z>0.6875)$

And we can find the probability with the complement rule and the normal standard distirbution and we got:

$P(z>0.6875)=1-P(z$

Step-by-step explanation:

Let X the random variable that represent the time spent reading of a population, and for this case we know the distribution for X is given by:

$X \sim N(49,16)$

Where $\mu=49$ and $\sigma=16$

We are interested on this probability

$P(X>60)$

And we can use the z score formula given by:

$z=\frac{x-\mu}{\sigma}$

Using this formula we got:

$P(X>60)=P(\frac{X-\mu}{\sigma}>\frac{60-\mu}{\sigma})=P(Z>\frac{60-49}{16})=P(z>0.6875)$

And we can find the probability with the complement rule and the normal standard distirbution and we got:

$P(z>0.6875)=1-P(z$

Will the following side lengths make a triangle? 7, 5, 4

Greeley [361]

Okay too answer this you have to take the two smallest numbers and add them, in this case the answer would be 5 + 4 = 9. The answer has to be greater than the last number, In this case, 7. So the answer is yes.
