1 answer:
SVEN [57.7K]3 years ago
3 0

Answer:

Answer is C, 7/20

Step-by-step explanation:

There are total 60 days and on the first 39 days she arrives before 8:30 am this means that we have only 21 days where she arrives after 8:30 am.

Now the question is asking: What are the chances of her arriving after 8:30 am that means that we only have 21 days where its \frac{21}{60}.

Dividing the numerator and denominator by 3 we end up with C.

Hope this helps

The equation of circle having a diameter with endpoints (-3, 1) and (5, 7) is
nydimaria [60]
The equation of a circle:
(x-h)^2+(y-k)^2=r^2
(h,k) - the coordinates of the center
r - the radius

The center is the midpoint of the diameter.
(-3,1) \\
x_1=-3 \\ y_1=1 \\ \\
(5,7) \\
x_2=5 \\ y_2=7 \\ \\
\hbox{the midpoint: } (\frac{x_1+x_2}{2},\frac{y_1+y_2}{2}) \\
\frac{x_1+x_2}{2}=\frac{-3+5}{2}=\frac{2}{2}=1 \\
\frac{y_1_y_2}{2}=\frac{1+7}{2}=\frac{8}{2}=4 \\
\Downarrow \\
(1,4) \\ h=1 \\ k=4

The radius is half the diameter, or the distance from one of the endpoints to the center.
r=\sqrt{(x_1-h)^2+(y_1-k)^2}=\sqrt{(-3-1)^2+(1-4)^2}=\\
=\sqrt{(-4)^2+(-3)^2}=\sqrt{16+9}=\sqrt{25}=5 \\ \Downarrow \\
r^2=5^2=25

The equation of the circle:
\boxed{(x-1)^2+(y-4)^2=25}

Which of the following statements best describes the effect of replacing the graph of y = f(x) with the graph of y = f(x + 6)? T
Alenkasestr [34]

Answer:

The graph of y = f(x) will shift left 6 units, as shown in figure a.

Step-by-step explanation:

A translation means we are able to move the graph of a function up or down - normally called Vertical Translation -  and right or left - commonly called Horizontal Translation.

If we replace the graph of y = f(x) with the graph of y = f(x + 6). It means we have added 6 units to the input, meaning the graph y = f(x) will shift left by 6 units as 6 is being added directly to the  x, so it is f(x + 6).

For example, if y = x² is the original function and of 6 is directly added to x i.e. f(x + 6), making it y = (x + 6)². So, we can easily observe that there will be a horizontal translation left of 8 units, as shown in figure a.

So, the graph of y = f(x) will shift left 6 units.
