Answer:
2.60
Step-by-step explanation:
z-score is the difference between the score and mean, divided by the standard deviation.
So 2.6 is an answer close enough.
Answer:
Step-by-step explanation:
We can write the equation of a line in 3 different forms including slope intercept, point-slope, and standard depending on the information we have. We have two standard form equations which we will get a slope and a y-intercept from. We will convert each to slope intercept form to get the information. We will then write a new slope-intercept equation and convert to standard form.
3x-5y=7 has the same slope as the line. Let's convert.
The slope is .
2y-9x=8 has the same y-intercept as the line. Let's convert.
The y-intercept is 4.
We take and b=4 and substitute into y=mx+b.
We now convert to standard form.
For standard form we need the coefficients of x and y to be not zero or fractions. We need integers but the coefficient of x cannot be negative. So we multiply the entire equation by -5 to clear the denominators.
Answer:
120?
Step-by-step explanation:
-5 times -2 equals 10 (since a negative times negative equals positive)
10 times -3 equals -30
-30 times -4 equals 120
