Answer: 54
Step-by-step explanation:
Volume is found when you multiply length times width by height, so you multiply all three numbers.
The easiest way to do this is to combine these into easier to multiply terms.
If you multiply two by three, you will end up with six.
When you multiply six by your last number, nine, you end up with fifty four, which is your volume.
Step-by-step explanation:
Circumference = 2πr
Therefore 2πr = 28π and r = 14in.
Answer:
C
Step-by-step explanation:
thee equation they give us is 2x + 18 = 32. Our goal is to isolate x.
First, subtract 18 from both sides to eliminate it.
2x + 18 = 32 ---> 2x + 18 - 18 = 32 - 18 ----> 2x = 14
Next, separate the 2 from the x by dividing it from both sides:
2x = 14 ----> 2x/2 = 14/2 ----> x = 7
By solving this equation, we find that x, or one sandwich, costs $7.
Step-by-step explanation:
First, find the expected value.
μ = 0 (0.28) + 1 (0.37) + 2 (0.22) + 3 (0.08) + 4 (0.05)
μ = 1.25
Now find the standard deviation.
σ² = (0−1.25)² (0.28) + (1−1.25)² (0.37) + (2−1.25)² (0.22) + (3−1.25)² (0.08) + (4−1.25)² (0.05)
σ² = 1.2075
σ = 1.099
If we were to select many boxes of bulbs randomly, the number of defective bulbs would typically vary about 1.099 from the mean.
These are in y=mx+b form where m=slope
sometimes b=0
vertical intercept means the y-intercept and the horizonatl intercept is the x intercept so the x intercept is when y=0 and the y intercept is when x=0 so the first one is
y=5x-15
slope=5
y-intercept=-15
x-intercept=3
y=7-x
this can be written as
y=-1x+7
slope=-1
y-intercept=7
x-intercept=7
4x=2y=12
we must get it into slope intercept form
divide the whole thing by 2x=y=12
we can disregard the 12 and get
2x=y or y=2x+0
slope=2
y-intercept=0
x-intercept=0
