Answer:

y = 10x + 100

Step-by-step explanation:

The 100 bonus points are guaranteed, no matter if you use the site for 0 months or more. Thus, 100 is the constant, the y-intercept in a graph.

The 10 points you earn for each month is the rate of change, or slope.

The equation is:

y = 10x + 100

where x represents the number of months used, and y is the total points.

As a function, the equation is:

p(x) = 10x + 100

where x is the number of months, and p meaning points.

For f(x)=3x+1 and g(x)=x^2-6, find (f o g)(x)

Eddi Din [679]

The answer is: " <span>3x² − 17 " .
______________________________________</span>
f(x) = 3x + 1 ;
________________________________________________
If g(x) = x² − 6 ;

then: (f o g)(x) = f(x² − 6) = 3x + 1 ;

= 3(x² − 6) + 1 = 3x² − 18 + 1 ;

= 3x² − 17 .

Suppose you want to estimate the proportion of traditional college students on your campus who own their own car. From research

Lapatulllka [165]

Answer:

2,655 students

Step-by-step explanation:

The z-score for a 99% confidence interval is z = 2.576

The standard error for a proportion p is:

$SE = z*\sqrt{\frac{p*(1-p)}{n} }$

For a proportion of p =0.20, in order to ensure a standard error of 0.02, the sample size 'n' must be:

$0.02 = 2.576*\sqrt{\frac{0.2*(1-0.2)}{n}}\\n=2,654.31$

Rounding up to the next whole student, the sample size needed is 2,655 students.

LiRa [457]

Answer:

The correct answer option is 192

Step-by-step explanation:

We are given the results of a random survey about the preferred service for streaming movies.

We are to find the number of people we would expect to prefer Company B.

Number of people using service B = 32

Total number of people = 125

Number of people expected to prefer Company B =32/125 x 750 = 192

PLEAZE HELP IM FAILING THIS CLASS 9) The volume of a box is represented by x' +11x² + 20x – 32. The width of the box is x – 1, a

In-s [12.5K]

Answer:

Step-by-step explanation:

Volume of the box = x³ +11x² + 20x – 32 I think the ' is a typo for ³

the width is x-1 and the height is x+8

Find an expression for the length

Vol = LWH solve L

Vol / (WH) = L so

L = (x³ +11x² + 20x – 32) / (x-1) (x+8)

so it would help to factor the numerator

(x³ +11x² + 20x – 32) I'm willing to bet (x-1) and (x+8) are factors

but I will plot the equation to find the three roots

(x³ +11x² + 20x – 32) = (x-1) (x+8) (x+4)

L = (x³ +11x² + 20x – 32) / (x-1) (x+8)

= (x-1) (x+8) (x+4) / (x-1) (x+8) the (x-1) and (x+8) cancel out leaving

L = (x + 4)

Emanuel added two integers.

Temka [501]

A. When you add to negative numbers, it is always negative. A positive + a positive is positive. In D, the answer is always 0. 1 + -1 is 0. In C, it varies. The bigger number not including the negative sign is the sign the number has. For example, -6 + 5 = -1. 6 is bigger than 5. You subtract the smaller number from the bigger number and that is the answer. You would then tack on the negative sign because it is -6, and 6 is bigger than 5.
