Answer:

The next step is;

Label the two intersection points

Step-by-step explanation:

To make a copy of an angle, the steps are;

1) Draw the rays of the original angle passing through the point B

2) Open the compass slightly and place the compass point on the vertices G where the two rays meet to draw an arc that intersect both rays

3) Label the point of intersection of both rays points C and D

4) With the compass still opened to the same width, move the compass to the point B on the line the angle is to be copied and draw a similar arc intersecting the ray at J

5) Open the compass to the width of C and D on the original angle and place the compass at point J to mark the arc on the copied angle location at M

6) Draw a line from B passing through M to complete the second ay of the copied angle.

Supposethat z is a normally distributed variable with variance 4. You collect a sample of size n for which you get a sample aver
Nikitich [7]

Answer:

The sample size is 4

Step-by-step explanation:

Null hypothesis: The mean is 2

Alternate hypothesis: The mean is less than 2

Mean = 3

sd = sqrt(variance) = sqrt(4) = 2

At 95% confidence level, t-value is 1.960

Assuming the lower bound of the mean is 1.04

Lower bound = mean - (t×sd/√n)

1.04 = 3 - (1.96×2/√n)

3.92/√n = 3 - 1.04

3.92/√n = 1.96

√n = 3.92/1.96

√n = 2

n = 2^2

n = 4

Write the equation of the linear function for which f(0)=3 and f^-1(0)=-2
Semmy [17]
We know that if f(a)=b then f^{-1}(b)=a
and
if f^{-1}(a)=b then f(b)=a
so


since f^{-1}(0)=-2 therefor, f(-2)=0

we have 2 points, (-2,0) and (0,3)

we can use slope intercept form
y=mx+b
m=slope
b=y intercept

we have when x=0, y=3, that is the y intercept
y=mx+3

substitute the other point
(-2,0)
x=-2, y=0
0=-2m+3
-3=-2m
divide both sides by -2
\frac{3}{2}=m


the equation is
y=\frac{3}{2}x+3
or
3x-2y=-6 in standard form

An athlete runs 8 miles in 50 minutes on a treadmill. At this rate, how long will it take the athlete to run 9 miles? *
I am Lyosha [343]

Answer:

50 minutes = 50/60 hours = 0.8333333333 hours

8 miles / 0.8333333333 hours = 9.60 miles per hour

9 miles / 9.60 miles per hour =

0.9375 hours = 56.25 minutes

The boeing 747 airplane is 250 feet in length. If a model of this airplane is 8 inches long, what scale was used to create the m
Deffense [45]

answer: The wingspan is 36 m.

Using a proportion to solve this, we write the scale factor as a ratio first:  19/38, since 19 is the size of the model's length and 38 is the real length.  For the second ratio, we have 18 for the size of the model wingspan and x for the real wingspan:

19/38 = 18/x

Cross multiply:

19*x = 38*18

19x = 684
