Nimfa-mama [501]

Answer:

Option a

Step-by-step explanation:

Given that all of the seniors and none of the freshmen voted for it.

Some of the juniors and some of the sophomores voted for the proposal and some voted against it.

If the proposal was to be adopted then a simple of majority of votes should have been cast.

Since all seniors voted for it, and no freshmen number of freshmen has to be less than seniors then only majority would have voted.

Regarding juniors and sophomores we assume some voted and some against thus approximately nullifying their votes.

So the correct option would be

a. There are more seniors than freshmen on the council.

Option b wrong since only some voted for it.

C is wrong because actual seniors were not given.

D is wrong because while seniors voted for sophomores voted against.

e is wrong since sophomores and freshmen nullified each other

Box 1 contains 3 blue and 5 red balls, whereas Box 2 contains 2 blue and 4 red ball. A ball is randomly chosen from Box 1 and th

muminat

Answer:

0.32

Step-by-step explanation:

Let A be the event that the transferred ball was blue.

B be the event that the red ball is selected from box 2

C be the event that the transferred ball was red

Then:

P(A) be the probability that the transferred ball was blue, which is 3/8

P(C) be the probability that the transferred ball was red, which is 5/8

P(B|A) is the probability that selected ball is red, given that the transferred ball was blue, which is 4/7

P(B|C) is the probability that selected ball is red, given that the transferred ball was red, which is 5/7

P(B) is the probability that the selected ball is red, which there are 2 scenarios, given that the transferred ball is blue and red

P(B) = P(B|A)P(A) + P(B|C)P(C)

$P(B) = \frac{4}{7}\frac{3}{8} + \frac{5}{7}\frac{5}{8}$

$P(B) = \frac{3}{14} + \frac{25}{56} = \frac{37}{56}$

P(A|B) is the probability that the transferred ball was blue, given that a red ball is selected from Box 2, which can be solved using Bayes theorem

$P(A|B) = \frac{P(B|A)P(A)}{P(B)} = \frac{\frac{4}{7}*\frac{3}{8}}{\frac{37}{56}} = \frac{3}{14}\frac{56}{37} = \frac{12}{37} = 0.324$

Harman [31]

Answer:

<h2>see below</h2>

Step-by-step explanation:

<h3>to understand this</h3><h3>you need to know about:</h3>

algebra
PEMDAS

<h3>let's solve:</h3>

given function:

$\quad \rm\: f(x) = - 2x +8$

when x is 0

$\sf \:f(0) = - 2.0 + 8$

simplify multiplication:

$\sf f(0) = 8$

when x is 3

$\sf f(3) = - 2.3 + 8$

simplify multiplication:

$\rm \: f(3) = - 8 + 8$

add:

$\rm \: f(3) = 0$

when x is 6

$\quad \rm\: f(6) = - 2.6 +8$

simplify multiplication:

$\quad \rm\: f(6) = - 12 +8$

simplify addition:

$\quad \rm\: f(6) = -4$

when x is 9:

$\quad \rm\: f(9) = - 2.9 +8$

simplify multiplication:

$\quad \rm\: f(9) = - 18 + 8$

simplify addition:

$\quad \rm\: f(9) = - 10$
