More data can be applied to the frequency distribution table. You can measure the "midpoint" (or "class mark") of each class as: Midpoint = Lower class limit + Upper class limit 2 . . The proportion of the data that falls in that class is the "relative frequency" of each class.
Answer:
<h2>The answer is 32</h2>
Step-by-step explanation:
3( 2c + d) - 4( c - d) + d²
when
c = 1
d = 3
Substitute the values of c and d into the expression and solve
That's
3[ 2(1) + 3 ] - 4( 1 - 3) + 3²
= 3( 2 + 3) - 4( - 2) + 9
= 3(5) + 8 + 9
= 15 + 17
We have the final answer as
<h3>32</h3>

Answer:
B)-4
Step-by-step explanation:
y=mx+c
sub in a point and gradient/slope to get c
-7=3(-1)+c
-7=-3+c
-7+3=c
c=-4
y=3x-4
if u looking for the y intercept make x=0
y=3(0)-4
y=-4
Answer:
D. 4.5%.
Step-by-step explanation:
Interest earned in 6 months = 572.6 - 560 = $12.60.
As a percentage this is (12.60 * 100) / 560
= $ 2.25%.
So the annual interest is 2 * 2.25
= 4.5%.
Answer:
x=1
Step-by-step explanation:
Simplify:
24x-12=12
add 12 on both sides:
24x=24
divide both sides by 24
x=1
