Answer:

For the experimental outcomes to be closer to the predicted outcome, the number of trials should be increased.

If the number of trials is changed, the experimental probability also changes.

If the number of trials is changed, the predicted number of outcomes also changes.

If the number of trials is changed, the number of experimental outcomes also changes.

A line passes through the point (-2, -6) and has a slope of
lapo4ka [179]

ANSWER: y = 2x + -6

EXPLANATION

Slop intercept for is

Y = Mx + b

Where Mx is the slope and b is they y intercept

The slope is 2 and the y intercept is -6

We know the y intercept cause it’s written (x,y) and -6 is in the y value spot.

So just plug in the numbers and you get

Y= 2x + -6

A line passes through (1, 9) and has a slope of 5, what is the equation of this answer? 20 Points.
ddd [48]

Because it has a slope of 5, we can already set up part of the equation:

y = 5x

Now, we need to find the y-intercept.

We can do that by subtracting 1 from the x value of the provided coordinate pair, and subtracting 5 from 9.

1 - 1 = 0

9 - 5 = 4

The y-intercept is 4.

<h3><u>Our equation is y = 5x + 4</u></h3>

Given that the net of the square pyramid is as shown above, the surface are of the pyramid will be given by:
SA=(number of triangles)*(area of triangle)*(area of square base)
area of one triangle will be:
A=1/2*base*height
A=1/2*0.8*0.75
A=0.3 sq. inches

area of the square base will be:
A=0.75*0.75
A=0.5625
Therefore the surface area will be:
SA=4*0.3*0.5625
SA=0.675 sq. inches
