A rectangle is transformed according to the rule r0, 90º. the image of the rectangle has vertices located at r'(–4, 4), s'(–4, 1

Korvikt [17]

Answer:

Clockwise vertices of q' ( -3 ,4) →→ q( 4 , 3 ).

Counter clock wise rule : q' (-3 ,4 ) →→ q( -4 , -3 ).

Step-by-step explanation:

Given : rectangle has vertices located at r'(–4, 4), s'(–4, 1), p'(–3, 1), and q'(–3, 4)

To find : transformed according to the rule 90º , what is the location of q?

Solution : we have given that

vertices located at r'(–4, 4), s'(–4, 1), p'(–3, 1), and q'(–3, 4).

By the rule of 90º rotation clock wise rule : (x ,y ) →→ ( y , -x )

90º rotation counter clock wise rule : (x ,y ) →→ ( -y , x ).

Then Clockwise vertices of q' ( -3 ,4) →→ q( 4 , 3 ).

counter clock wise rule : q' (-3 ,4 ) →→ q( -4 , -3 ).

Therefore, Clockwise vertices of q' ( -3 ,4) →→ q( 4 , 3 ).

counter clock wise rule : q' (-3 ,4 ) →→ q( -4 , -3 ).

The result after adding a set of numbers or is called a ___.

german

Answer:

The result after adding a set of numbers or is called a sum.

Step-by-step explanation:

Consider the provided information.

The four mathematical operations are:

$+,-,\times ,\div$

The sign + is used to add numbers.

The sign - is used to subtract the numbers.

The sign × is used for the product of the numbers.

The sign ÷ is used for division of the numbers.

When we add two or more number by using the operator + the obtained number or value is called the sum of the numbers.

For example:

Consider the number: 2 + 5 if we add the number the resulting value will be 7.

The number 7 is the sum of 2 and 5.

Thus, the result after adding a set of numbers is called a sum.

galben [10]

Answer:

The mean is 27.8

The required variance is 23.9358

Step-by-step explanation:

Consider the provided information.

Here the random sample size, n = 200

Unemployment rate is 13.9% = p = 0.139

Part (a) expected number of grads who are unemployed.

$Mean = np\\Mean = 200\times 0.139\\Mean = 27.8$

Hence, the mean is 27.8

Part (b) variance of the random variable "number of grads who are unemployed.

$Variance = np(1-p)\\Variance = 200\times 0.139(1-0.139)\\Variance = 27.8(0.861)\\Variance = 23.9358$

Hence, the required variance is 23.9358
