Y=15x + 35

$35 is the upfront charge for the boat rental.  it has nothing to do with the # of hours the boat is rented.

$15/hr is the hourly rental rate.

If you rent the boat for 1 hour, you'll pay y = $35 + ($15/hr)(1) = $50.

If you rent the boat for 2 hours, you'll pay y = $35 + ($15/hr)(2) = $65.

And so on.

The demand for a daily newspaper at a newsstand at a busy intersection is known to be normally distributed with a mean of 150 an
AURORKA [14]

Answer:

171 newspapers.

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean \mu and standard deviation \sigma, the zscore of a measure X is given by:

Z = \frac{X - \mu}{\sigma}

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this problem, we have that:

\mu = 150, \sigma = 25

How many newspapers should the newsstand operator order to ensure that he runs short on no more than 20% of days

The number of newspapers must be on the 100-20 = 80th percentile. So this value if X when Z has a pvalue of 0.8. So X when Z = 0.84.

Z = \frac{X - \mu}{\sigma}

0.84 = \frac{X - 150}{25}

X - 150 = 0.84*25

X = 171

So 171 newspapers.

What is the vertex of the graph of y = −1(x − 2)2 + 3?<br> (3,-2)<br> (-2,3)<br> (3,2)<br> (2,3)
aleksley [76]
The vertex form is y=a(x-h)²+k
the vertex is (h,k)
so

y=-1(x-2)²+3
compare to
y=a(x-h)²+k
2=h and 3=k
the vertex is  (2,3)

Solve for a. Correct answer gets BRAINLIEST
Darina [25.2K]

Hey there!!

Equation given :

A = h ( a + b ) / 2

Multiply by 2 on both sides

2A = h ( a + b )

Divide by h on both sides

2A / h = a + b

Subtract by b on both sides

2A / h - ( b ) = a

Hence, the option ( a ) is the correct answer

Hope my answer helps!

Answer:

<h3>          The second:   f(-5) = 2</h3>

Step-by-step explanation:

x = -5

-5 < -4  and if x<-4 then  f(x) = - 2x - 8

so:

    f(-5) = - 2(-5) - 8 = 10 - 8 = 2
