<span>Your bowl contains 8 red balls, and 9 blue balls, and you draw 4 balls. in how many ways can the selection be made so that at least one of each color is drawn.</span>
Answer:
-30/15 or -2
Step-by-step explanation:
2+8 = 10
3+2 = 5
14-2 = 12
4-1 = 3
10/5 - 12/3
(Find GCF)(GCF = 15)(5 times 3)
30/15 (10/5 times 3)
60/15 (12/3 times 5)
30/15 - 60/15 = -30/15 --> -2(simplified to 2)
Answer:
Cluster sampling.
Step-by-step explanation:
Samples may be classified as:
Convenient: Sample drawn from a conveniently available pool.
Random: Basically, put all the options into a hat and drawn some of them.
Systematic: Every kth element is taken. For example, you want to survey something on the street, you interview every 5th person, for example.
Cluster: Divides population into groups, called clusters, and each element in the cluster is surveyed.
Stratified: Also divides the population into groups. However, then only some elements of the group are surveyed.
In this question:
People divided into groups, by households.
Each member of the households(group) is surveyed, so cluster sampling.
Answer: 6(17+14) or 186
Step-by-step explanation: I provide with you two answers since not sure what u mean .And the first answer is distributive it and the second answer is the sum.
Also 102 + 84 is an expression already so I don't know what your asking and if this help u are welcome !
M= y2-y1?x2-x1
m=4-(-1)/(-7)-8
m=5/-15
m=-3
The slope is -3
