Answer:
Step-by-step explanation:
From the question we are told that:
Percentage of Green beads 
Percentage of Red beads 
Percentage of Purple beads 
Therefore
Probability of choosing a Green bead is
Probability of choosing a Red bead is
Generally the equation for choosing a green bead then a red bead is mathematically given by
Since Outcomes are independent
we have that
−4+8−16+32−.....
a1=-2*(-2)-----> -4
a2=-4*(-2)-----> +8
a3=+8*(-2)-----> -16
a4=-16*(-2)----> +32
a5=+32*(-2)----> -64
a6=-64*(-2)-----> +128
a7=+128*(-2)-----> -256
The sum of the first 7 terms of the series is
<span>[a1+a2+a3+a4+a5+a6+a7]-----> [-4+8-16+32-64+128-256]------->
-172</span>
<span>
the answer is -172</span>
Answer:
5824
Step-by-step explanation:
10% of 6400 =640
1% 0f 6400 = 64
640-64=576
6400-576= 5824
Answer:
Example: the median is not affected by very large or very small values (outliers).
Step-by-step explanation:
Suppose my income for 5 months is $1000, $1500, $1550, $2000, $90,000. (I hit the lottery in the last month!).
The median is the number in the middle: $1550. That $90,000 would increase the <u>mean</u> ("average") by a lot, but the median is unchanged.
If a newspaper story reports the median house price in a neighborhood is $93,000, that million dollar mansion on the corner won't change the median. Half the prices are less than $93,000 and half are greater.
We are asked to evaluate dx/dy of the function x^2y+xy^2=6
we use implicit differentiation here:
2xy dx + 2xy dy = 0we can cancel 2xy from both terms in the left-hand side such that what is left is dx/dy = 0
