Answer:
mean = 2.55
Standard deviation = 1.118
Step-by-step explanation:
Probability of babies who are boys
P = 0.51
Then we have q = 1-p
= 1-0.51
= 0.49
We have n = 5
We calculate the mean as:
np
= 0.51x5
= 2.55
Therefore mean = 2.55
The standard deviation
= √variance
= √npq
= √0.51x5x0.49
=√1.2495
= 1.118
First of all, if we want to graph this we will need to make it into slope intercept form
2x - y = 3
add y to both sides
2x = y + 3
subtract 3 from both sides
2x - 3 = y
flip the equation
y = 2x -3
we now know that the y-intercept is at (0, -3)
using that we plot the first point
The slope is 2
(this means up 2 over 1)
using that we make a line
(I'm sure you can graph it ;D)
Hope this helps :)
Answer:
p = 5.88/3 –.75
The original be price was $1.21 per lb pound
Step-by-step explanation:
To find the new price per pound, divide 5.88 by 3.
Then subtract .75 from the new be price to find the original price.
5.88/3 = 1.96
1.96 –.75 = 1.21
Dimensions possible are:
80x1
40x2
20x4
10x8
5x16
The dimension that makes most sense is the 5 by 16 for a pot holder.
