Mean=total/the number of values =>total=mean*the number of values
the total of the first set of 8 numbers is : total=8*8=64
the total of the second set of 12 numbers is: 12m
the total of the 20 numbers is: 64+12m
the mean of the 20 number is: (64+12m)/20=5
solve for m: 64+12m=100
12m=36
m=3
Answer:
C
Step-by-step explanation:
The triangle is an equilateral triangle, which is equal on all three sides in both side length and angle. since one of them of 60 degrees, then all of them would also be 60 degrees. Since the total amount of degrees in a triangle is 180, 60*3=180 so the answer is C.
Answer: $32
Step-by-step explanation:
No. You can’t add the two lower numbers up to make the bigger number making them not a triangle.
y = 5x + 4 is the equation of the line whose slope is 5 and y intercept is (0,4)
<em><u>Solution:</u></em>
Given that, we have to write the equation of the line whose slope is 5 and y intercept is (0,4)
<em><u>The equation of line in slope intercept form is given as:</u></em>
y = mx + c ---- eqn 1
Where, "m" is the slope of line and "c" is the y - intercept
Given that, slope = m = 5
y intercept is (0, 4)
So, c = 4
<em><u>Substitute c = 4 and m = 5 in eqn 1</u></em>
y = 5x + 4
Thus the equation of line is found
