Answer:

k=4-p\frac{p}{x}

Step-by-step explanation:

Given : Expression x(4-k)=p

To find : Solve for k?

Solution :

Step 1 - Write the expression,

x(4-k)=p

Step 2 - Divide by x both side,

\frac{x(4-k)}{x}=\frac{p}{x}

4-k=p\frac{p}{x}

Step 3 - Taking k to one side,

k=4-p\frac{p}{x}

Therefore, k=4-p\frac{p}{x}

If cot theta= 4/3, find csc theta
Marrrta [24]

Answer: Option d.

Step-by-step explanation:

The trigonometric identity needed is:

csc^2\theta=cot^2\theta+1

Knowing that cot\theta=\frac{4}{3}:

Substitute it into csc^2\theta=cot^2\theta+1:

csc^2\theta=(\frac{4}{3})^2+1

Simplify the expression:

csc^2\theta=(\frac{4}{3})^2+1\\\\csc^2\theta=\frac{16}{9}+1\\\\csc^2\theta=\frac{25}{9}

Solve for csc\theta. Apply square root at both sides of the expression:

\sqrt{csc^2\theta}=\±\sqrt{\frac{25}{9}}

csc\theta=\frac{5}{3}

A random sample of n = 16 professors from a university has been selected; salaries have been plotted on the following Q-Q plot.
Semenov [28]

Answer:

The objective of the confidence interval is to give a range in which the real mean of the population is placed, with a degree of confidence given by the level of significance.

The conclusion we can make is that there is 95% of probability that the mean of the population (professor's average salary) is within $99,881 and $171,172.

Step-by-step explanation:

This is a case in which, from a sample os size n=16, a confidence interval is constructed.

The objective of the confidence interval is to give a range in which the real mean of the population is placed, with a degree of confidence given by the level of significance. In this case, the probability that the real mean is within the interval is 95%.

the profit of a business are RM 29,000. It is shared between two partners A &amp; B. If A receives 9/20 of the profit, how much
Aneli [31]
B earns 11/20 of the profit.

(20-9)/20 = 11/20.

If the actual value is needed. You could do it one of two ways.

1---> 29000*11/20 = 15,950


2---> 29000*9/20 = 13,050
               29,000 - 13,050 = 15,950
