Answer:

Correct option: A -> Horizontal or vertical reflection

Step-by-step explanation:

We can observe that the value of x in f(x) gives a value that is the same value we have in g(x) with the value -x.

That is, x = 1 in f(x) gives the same result as x = -1 in g(x)

So this means that these functions are a reflex of each other in relation to the y-axis, as the x values of one have the same result as (-x) values for the other one.

So the correct option is A: Horizontal or vertical reflection

(It is a horizontal reflection)

78% of U.S. adults think that political correctness is a problem in America today. You randomly select six U.S. adults and ask

nikdorinn [45]

Answer:

mean= 4.68

variance= 1.0296

Step-by-step explanation:

mean= n×p

n=6

p=0.78

mean= 6×(0.78)

= 4.68

variance= n×p×(1-p)

= 6 × 0.78×(1-0.78)

= 1.0296

A survey of 250 homeless persons showed that 14 were veterans. Find a point estimate for the population proportion of homeless p

snow_lady [41]

Answer:

$\hat p =\frac{14}{250}= 0.056$

And for this case that represent the 5.6% of the homeless persons who are veterans

Step-by-step explanation:

We know that in a survey of 250 homeless persons 14 were veterans. We can find the estimated proportion of homeless persons who are veterans with the following formula:

$\hat p =\frac{X}{n}$

The last one is an unbiased estimator of the true population proportion p

And replacing the info given we got:

$\hat p =\frac{14}{250}= 0.056$

And for this case that represent the 5.6% of the homeless persons who are veterans

Find the surface area and volume of a cylinder with a diameter equal

dangina [55]

Answer:

Volume = 1539.38 cm³

Surface Area = 747.7 cm²

Step-by-step explanation:

Volume = πr² h

V = π(7)²(10)

V = π(49)(10)

V = 490π

V = 1539.38 cm³

Surface Area = 2πrh + 2πr²

SA = 2π(7)(10) + 2π(7)²

SA = 2π(70) + 2π(49)

SA = 140π + 98π

SA = 238π

SA = 747.7 cm²
