Jamie and Hudson took a road trip to the beach. Their total distance traveled after getting on the highway can be found using th

lukranit [14]

The total distance is an illustration of a linear function.

(1) Why the relationship is a function

The relationship is a function because all input values of h, have exactly one corresponding output value of d

(2) The function type

The function is a discrete function, because the number of hours is an integer, and it cannot take decimal values (in this case)

(3) The domain for a drive of 8 hours

The domain is the set of time the girls drive.

So, the domain is: [0,8]

(4) The range

The function is given as:

$d = 55h +10$

When h = 0,

$d = 55(0) +10 = 10$

When h = 8,

$d = 55(8) +10 = 450$

So, the range is: [10,450]

(5) The graph

See attachment

(6) The slope

A linear function is represented as:

$y = mx + c$

Where:

m represents the slope.

So, by comparison:

$Slope = 55$

The slope in this case represents the distance travelled per hour

(7) The y-intercept

In (6) above, c represents the y-intercept.

So, by comparison:

$c = 10$

The y-intercept in this case represents the initial distance

) furnace repair bills are normally distributed with a mean of 272 dollars and a standard deviation of 15 dollars. if 36 of thes

nexus9112 [7]

To evaluate the given probability we proceed as follows:
The z-score is given by:
z=(x-μ)/σ
where:
μ-mean
σ-standard deviation
from the question:
mean=272, sig=15
but the sample is n=36, thus we shall have:
√σ/n
=15/√36
=2.5
thus the z-score will be as follows:
x=272
z=(272-272)/2.5=0
x=274
z=(274-272)/2.5==0.8
thus
P(272<x<274)
=P(z<0.8)-P(z<0)
=0.7881-0.5
=0.2881
Hence the answer is 0.2881
