Replace n in the equations with 1 and then 3 and see which one will equal 60 for 1 night and 150 for 3 nights.

The equation that works is B. c = 45n +15

Answer: Option B

Step-by-step explanation:

$60 per 1 night

$150 per 3 nights

If this is a linear c(n) function, que can obtain the slope by:

s = (c2 - c1)/(n2 - n1)

where c2 = c(n2) and c1 = c(n1)

in this case y is the price and n is the number of nights.

s = ($150 - $60)/(3 - 1) = $90/2 = $45

Then c(n) = $45*c + b

we know that c(1) = $60 = $45*1 + b

b = $60 - $45 = $15

then the linear equation is:

c(n) = $45*n + $15

3√24= 3√2^2*6 = 3*2√6 = 6√6

2√384= 2√8^2*6 = 2*8√6 = 16√6

√96= √4^2*6 = 4√6

6√6 -16√6- 4√6 = -14√6

Final answer: -14√6

Which model best fits the set of data shown on this graph?
Blizzard [7]

Answer:

C

Step-by-step explanation:

Quadratic model is shaped like a "U", or a parabola

Quartic model is shaped like a "W", highest degree is 4 (x^4).

Linear model is a line.

Cubic model is x^3, shaped like a curvy snake.

Looking at the graph, it <em>clearly</em> shows a line. So, linear model is the answer.

C is the correct answer.

HEY GUYS I NEED THIS ANSWER NOW
Sergio [31]

Let

x-------> the number of fiction books

y-------> the number of nonfiction books.

we know that

x+y=26 -----> equation 1

x=y+12

x-y=12 -----> equation 2

Add equation 1 and equation 2

x+y=26\\x-y=12\\ ------\\ 2x=38\\ x=38/2\\x=19\ fiction\ books

<u>find the value of y</u>

x+y=26

19+y=26

y=26-19=7\ nonfiction\ books

therefore

<u>the answer is</u>

Part a)  the number of fiction books is 19\ fiction\ books

Part b)  the number of nonfiction books is 7\ nonfiction\ books

Let x have a normal distribution with mean µ = 30 and standard deviation σ = 10. calculate p(x &gt; 40), and round your answer t
Gnesinka [82]

The random variable X is normally distributed with mean μ=30 and standard deviation σ =10. Use the transformation \frac{X-\mu}{\sigma} for calculating the probability. This value is called Z-score.

The Z score is Z=\frac{40-30}{10} =1.

Refer to the standard normal distribution table.

The probability

P(X>40)=P(Z>1)=1-P(Z
