Answer:
So Height of the box is 5.906
Step-by-step explanation:
Given:
Volume of box = 567
Length = 12
Width = 8
To Find:
Height = ?
Solution:
We know that a box is in the shape of a cuboid so
We know that
Volume of the cuboid is given by the formula which is
Volume = Length * Width * Height
Now we are given all the values in the question
putting in those values
Volume = Length * Width * height
Putting the values
567 = 12 * 8 * Height
567 = 96 * Height
Dividing both sides by 96 we get
Height = 567 / 96
So We get
Height = 5.906
So Height of the box is 5.906
Answer:
P(x) = (x - 1)(x + 2)(x - 3)(3x + 1)
Step-by-step explanation:
Since P(1) = 0 and P(- 2) = 0, then
(x - 1) and (x + 2) are factors of P(x)
(x - 1)(x + 2) = x² + x - 2 ← is also a factor of P(x)
dividing 3 - 5x³ - 17x² + 13x + 6 by x² + x - 2 gives
P(x) = (x - 1)(x + 2)(3x² - 8x - 3) = (x - 1)(x + 2)(x - 3)(3x + 1)
5X+yb=zmh
5x+yb-yb=zmh-yb
5x=zmh-yb
5x/5=zmh/5-yb/5
x=mhz-by/5
Answer:
(i) The student who weighed the rock 20 times.
Step-by-step explanation:
The margin of error of a confidence interval is:
In which z is related to the confidence level, is the standard deviation of the population and n is the size of the sample.
From the equation above, the larger the size of the sample, the lower the margin is, that is, the narrower the interval is.
In this question:
A student weighed the rock 20 times and other the 5. From above, the one who weighed the rock 20 times will have the more precise interval.
So the correct answer is:
(i) The student who weighed the rock 20 times.
