Mathematics

1 answer:

Pie3 years ago

7 0

Answer:

A, B, C

Step-by-step explanation:

The parent function of a linear equation is

y=x

where the y intercept is at the origin therefore A applies

linear lines are straight lines

and the slope of the equation is 1 since we can assume the coefficient before the x in the equation =1

It is NOT choice D because if this would mean that the equation of the parent function has a negative slope which is not true

hope this helps

A circle has a radius of 12 inches. Find the length of the arc intercepted by a central angle of 120 degrees to the nearest tent

OlgaM077 [116]

Answer:

25.12 inches

Step-by-step explanation:

We have given the radius of the circle =12 inches

The central angle intercepted by the arc =120°

We have to find the length of the arc

So length of the arc is given by $2\pi \times r\times \frac{central\ angle}{360}$

$=\frac{2\times \pi \times 12\times 120}{360}=25.12inches$

So the length of the arc will be 25.12 inch

Of all individual tax returns, 37 percent include errors made by the taxpayer. If IRS examiners are assigned randomly selected r

Dima020 [189]

Answer:

mean=4.44

standard deviation=1.67

Step-by-step explanation:

The mean and standard deviation for the number of erroneous returns per batch can be calculated using binomial distribution. The binomial distribution is used because

i) There are one of two possible outcomes( error or no error) that can be categorized into success and failure.

ii) The experiment is repeated fix number of times 12.

iii) The probability of success remains constant at each trial i.e. 37%

iv) The trails are independent.The mean and standard deviation of binomial distribution are np and √npq

Here, n=12, p=0.37 and q=1-0.37=0.63

mean=12*0.37=4.44

standard deviation=√12*0.37*0.63=√2.8=1.67
