5 0

Answer:

(C)  c(sin(B))=b(sin(C))  

Step-by-step explanation:

Given: In ΔABC, AD⊥BC.

To prove: \frac{sinB}{b}=\frac{sinC}{c}

Proof:

Statement                                     Reason

1. In ΔABC, AD⊥BC.                      Given

2. In ΔADB, sinB=\frac{h}{c}              Definition of sine

3. c(sinB)=h                            Multiplicative property of equality

4. In ΔACD, sinC=\frac{h}{b}              Definition of sine

5.  b(sinC)=h                            Multiplicative property of equality

6. c(sin(B))=b(sin(C))              Substitution

7. \frac{sinB}{b}=\frac{sinC}{c}   Division property of equality.

Hence proved.

Therefore, option C is correct.

Can anybody show me the steps to answering this question? 7x - 2z = 4 - xy<br> (solve for x)
Fed [463]

Answer: 2z+4/y+7

Step-by-step explanation:

We are trying to solve for x

7x-2z=4-xy

Add xy to both sides:

7x-2z+xy=-xy+4+xy= xy+7x-2z=4

Then you add 2z to both sides:

xy+7x-2z+2z=4+2z

xy+7x=2z+4

Then you factor out variable x

x(y+7)=2z+4

You divide both sides by y+7

x(y+7)/y+7= 2z+4/y+7

Which we would get x=2z+4/y+7

Since 12 friends share four pizzas equally,

3 friends share a pizza equally.

Hence, each friend gets 1/3 of a pizza.

A simple random sample of size n=10 is obtained from a population that is normally distributed with a mean of 40 and a standard
Eva8 [605]

Yes, the sampling distribution is normally distributed because the population is normally distributed.

A sampling distribution is a chance distribution of a statistic obtained from a larger variety of samples drawn from a specific populace. The sampling distribution of a given population is the distribution of frequencies of a variety of various outcomes that would probable occur for a statistic of a populace.

A sampling distribution is a probability distribution of a statistic this is obtained via drawing a huge variety of samples from a particular populace. Researchers use sampling distributions so that you can simplify the technique of statistical inference.

Solution :

mean = μ40

standard deviation σ σ= 3

n = 10

μx =  40

σ x = σ√n =  3/√10  = 0.9487

μ x =  4σ\x = 0.9487

σx = 0.9487

Yes, the sampling distribution is normally distributed because the population is normally distributed.
