What is Jackie's monthly salary if her annual gross pay is $65,400

3. A carpenter is framing a window with wood trim where the length of the window is 6 and 2\3 feet. If the width of the window i

wel

We can see that window is in shape of rectangle. So the length of the required wood to frame window is equal to the perimeter of rectangle.

SO the length of rectangular window is $= 6 \frac{2}{3} = \frac{20}{3}$ feet.

Width of the rectangular window is = $7 \frac{3}{4} = \frac{31}{4}$ feet.

In general parameter of rectangle is = $2(l+b)$

So the parameter of window is = $2( \frac{20}{3} + \frac{31}{4}) = 2* \frac{(80+ 93)}{12} = 2* \frac{173}{12} = 28.834$

So the required length of wood to frame window is = 28.834 feet

Question 7(Multiple Choice Worth 2 points)

agasfer [191]

The approximate value of 九十√70 is 11.51, correct option is 11.51.

<h3>What is an approximation?</h3>

An approximation is anything that is similar, but not exactly equal, to something else.

Now, the value of 九 is given as 22/7 is 3.142

To the nearest hundredth, it can be written as 3.14

The value of +√70 is given as 8.366

To the nearest hundredth as 8.37

For the required value of the expression we can write,

九十√70

Put the value of 九 = 3.14

and value of √70 = 8.37

Putting values in expression we have,

九十√70 = 3.14 + 8.37

⇒九十√70 = 11.51

Hence,the approximate value of 九十√70 is 11.51.

So,the correct option is 11.51.

A polygraph (lie detector) is an instrument used to determine if an individual is telling the truth. These tests are considered

Leya [2.2K]

Answer:

A) P(Type I error) = 0.045

B) P(Type II) error = 0.1

Step-by-step explanation:

We are told that the reliability of the test is 90% reliable.

Also, we are told that the probability that the test erroneously detects a lie even when the individual is actually telling the truth is 0.045.

Thus;

A) To calculate the probability of type I error:

From statistics, in this question we can say that the probability of a type I error is the probability that the test will erroneously detect a lie even though the individual is actually telling the truth. Thus;

Probability of (type I error) = P(rejecting true null) = 0.045

B) For probability of type II error, it is defined as the error where we accept a null hypothesis that is false. We can say that it produces a false negative and the formula is;

P(Type II) error = 1 - reliability

Reliability in the question is 0.90

Thus;

P(Type II) error = 1 - 0.9

P(Type II) error = 0.1
