Describe the steps used to graph the equation 4x-2y=8 with an x- and y- intercepts.
hram777 [196]

Answer:

x=1/2y+2

y=2x-4

Explanation:

For x-intercept:

4x-2y=8

-> subtract -2y on both sides

4x=2y+8

-> divide 4 on both sides to isolate the x

x=1/2y+2

For y-intercept:

4x-2y=8

-> subtract 4x on both sides

-2y=-4x+8

-> divide -2 on both sides to isolate the y

y=2x-4

Large birds like pheasants often walk short distances. Small birds like chickadees never walk. They either hop or fly. Why might
nevsk [136]

Answer:

Large birds can't fly due to higher weight and weak wings.

Why large birds can't fly?

Large birds like pheasants often walk short distances whereas small birds like chickadees never walk but fly because the large birds have more weight which can't support by the wings to fly in the sky so they walk on the land instead of flying.

While on the other hand, small birds have lower weight and easily fly in the sky so they don't need to walk on the ground so we can conclude that large birds can't fly due to higher weight and weak wings.

Suppose that IQ scores have a bell-shaped distribution with a mean of 101 and a standard deviation of 12. Using the empirical ru
7nadin3 [17]

95.44% IQ scores are between 77 and 125

We're given,

Mean (a)=101

standard deviation (b)=12

To find : P[77 < x < 125]

Using Empirical Rule:

∴ P[77 < x < 125]  = P[\frac{77-101}{12} < \frac{x-a}{b} < \frac{125-101}{12}]\\

=P[-2 < z < 2]\\

=P[Z < 2]-P[Z < -2]\\

=0.9772-0.0228\\

=0.9544 =95.44% (approx)
