The card one is 4/52 for kings but then 20/51 because you take a card the first time and you do not replace it.
The marbles is 1/4 chance. 10 green 10 not. For ball 1 it’s a 1/2 (50:50) chance of picking green. that’s reduce because you want to pick 2 green balls (25% chance)
Answer:
This is example of cluster sampling.
Step-by-step explanation:
The commissioner randomly selects 2 teams from all 30 MLB teams and has everyone on that team drug tested.
This is an example of Cluster sampling.
Cluster sampling is a sampling method, where population is divided into clusters and then each sample from a selected cluster is sampled.
Yes this is also a random sample.
<h3>Explanation:</h3>
(16^4 -2^13 -4^5) mod 11 = ((2^4)^4 -2^13 -(2^2)^5) mod 11
= (2^16 -2^13 -2^10) mod 11
= (2^10 mod 11)·((2^6 -2^3 -1) mod 11)
= (1024 mod 11)·(55 mod 11)
= 1 · 0 = 0
When the sum shown above is divided by 11, its remainder is zero. Hence the sum is divisible by 11.
1)
c=(107.5/100)(79.95+2(19.99))
c=1.075(79.95+39.98)
c=1.075(119.93)
c=128.92475
c≈$128.92 (to nearest cent)
2)
w=1700(10.5/100)
w=$178.50
3)
m=1700(1.25/100)
m=$21.25
4)
ss=1700(5.7/100)
ss=$96.90
5)
I=175(.035)*5+175(.035)*4+175(.035)3...
I=175(.035)(5+4+3+2+1)
I=175(.035)(15)
I≈$91.89 to nearest cent
6)
I=Pr^t-P
I=500(104.2/100)^7-500
I=500(1.042^7-1)
I≈$167.00 to nearest dollar
7)
A=(50+11*0.89)/11≈$5.44 per lb
B=(57+11*0.49)/11≈$5.67 per lb
C=(60-5)/11=$5.00 per lb
D=(58*(100-10)/100)/11≈$4.75 per lb
So D is the best deal at just $4.75 per lb.
Hi there!
Since the formula for finding the perimeter of a rectangle is length×2 + width × 2, we can follow this rule.
2 (4x + 5) + 2 (8x - 4)
= 8x + 10 + 16x - 8
= 24x + 2
So, the perimeter is 24x + 2.
Hope this helps!
