Answer:

<u>1/ 130 is the probability that they are the 4 oldest people in the group. </u>

Step-by-step explanation:

In the question, we are given; group of 11 people, 4 are selected randomly, find probability they are the 4 oldest people from the group

P(O)= <em>favorable number of outcomes / total number of outcomes </em>

<h3>= 1 / 11C4</h3>

=  11! / (11-4)! 4!

=  7! *4! / 11!

=1/ 130

<em>Therefore, 1 / 130 is the probability that they are the 4 oldest people in the group. </em>

stealth61 [152]

Answer:

C. y=\frac{4}{5}x+7

Step-by-step explanation:

Alan and his classmates found that the line of best fit through the data had the equation y=-\frac{5}{4}x+18

The slope of this line is m=-\frac{5}{4}

If a line would intersect this line of best fit at right angles, then the two lines are perpendicular to each other.

The slopes of perpendicular lines are negative reciprocals of each other,

Hence that line must have slope \frac{-1}{-\frac{5}{4}} =\frac{4}{5}

Therefore we look for a line whose slope is \frac{4}{5} from the given options.

That line is the third option y=\frac{4}{5}x+7

You pick one card from a standard deck of 52 cards. What is the probability that the card will be a two?
Natali [406]

Answer:

4 out of 52 or simplified 2 out of 26

Step-by-step explanation:

There are 4 suites of cards, spades, hearts, clubs, diamonds and there is one card for two in each suite, so we therefore know that the probability of picking a two out of a 52 card deck will be four out of 52 or the simplified answer would be 2 out of 26. Hope this helps, have a great day!
