The answer is C. x=3 2(3)^3=54
Answer:
x = 2 1/4 or 2.25
Step-by-step explanation:
to start we can make an equation
9lbs = 4x
divide by 4
9/4 = x
x = 2.25 or 2 1/4
Answer:
Step-by-step explanation:
From the information given,
Mark: 6,7,8,9,10
frequency:5,4,7,10,4
a) Range = highest mark - lowest mark
Range = 10 - 6 = 4
b) The number of students in the group is the sum of the frequency. Therefore,
Number of students = 5 + 4 + 7 + 10 + 4 = 30 students
c) Mean mark = (mark × frequency)/total frequency
[(6 × 5) + (7 × 4) + (8 × 7) + (9 × 10) + 10 × 4)]/ 30
Mean mark = (30 + 28 + 56 + 90 + 40)/30 = 244/30
Mean mark = 8.1
Answer:
I believe it would be, 410
explanation:
Inputs are x’s
Substitute the 18 where you see the x
y = 23(18) – 4
y= 414 – 4
y = 410
