<u>Answer:</u>

<u>Step-by-step explanation:</u>

We are given the data of number of cars observed waiting in line at the beginning of 2 minute intervals between 3 and 5 p.m. on Friday.

We are to find the probability (in percent) that there is no one in line.

Sum of frequencies = 2 + 9 + 16 + 12 + 8 + 6 + 4 + 2 + 1 = 60

Frequency of no car in line = 2

P (no car in line) = 2 / 60 × 100 = 3.3% ≈ 3%

An exponential relationship has a growth factor of3and y-intercept of 4.Evalute the function that represents the function that r

Murrr4er [49]

Answer:

$f(10)= 236196$

Step-by-step explanation:

Given

$(x,y) = (0,4)$ --- y intercept

$b = 3$ --- growth factor

Required

$f(10)$

An exponential function is represented as:

$y = ab^x$

$(x,y) = (0,4)$ means

$4=a * b^0$

$4=a *1$

$a= 4$

So, we have:

$y = ab^x$

$y = 4(3)^x$

$f(x)= 4(3)^x$

When x is 10, the value of the function is:

$f(x)= 4(3)^x$

$f(10)= 4(3)^{10$

$f(10)= 236196$

Can you please help me. I think it is x=0 and x=3

stiks02 [169]

When the graph is constant, you have to look for when it draws a straight line.
Look at the x axis, since it asks for the x value.

Your answer is correct! When x = 0, to x = 3, the function is constant.

If two angles are abtuse then they must be congruent

guajiro [1.7K]

Answer:

False

Step-by-step explanation:

An obtuse angle is an angle greater than 90 and smaller than 180.

Both 120 and 135 are obtuse angles.

But they are not congruent.
