Calculate the distance between the points N=(-5, 9) and P=(-1, 2) in the coordinate plane.

One card is selected at random from a deck of cards. Determine the probability that the card selected is a card greater than 3 a

Svetlanka [38]

Answer:

4/13

Step-by-step explanation:

Count all cards that are 4, 5, 6, and 7 (each of 4 different suits) so the number of cards that is greater than 3 and less than 8 = 4(4) = 16.

There are 52 cards in a standard deck of cards.

P(greater than 3 and less than 8)

= 16/52

= 4/13

Jackie is practicing free throws after basketball practice. She makes a free throw shot with probability 0.7. She takes 20 shots

Sergeu [11.5K]

Answer:

n = 20 q = 0.7, q = 0.3

Step-by-step explanation:

For each shot that she takes, there are only two possible outcomes. Either she makes or, she does not make is. The probability of making each shot is independent from other shots. So we use the binomial probability distribution to solve this problem.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

In which $C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

And p is the probability of X happening.

We also ahve that q = 1-p.

Jackie is practicing free throws after basketball practice. She makes a free throw shot with probability 0.7.

This means that $p = 0.7$ and $q = 1-p = 0.3$

She takes 20 shots.

This means that $n = 20$

So the correct answer is:

n = 20 q = 0.7, q = 0.3

Answer question 10( I do not understand stand it)

omeli [17]

You would have to plot the vertices and play a sort of game of connect the plots ( *Or connect the dots but more literally, the plots*) Then decide whether or not your final illustrations have the potential to be similar. If so, why?

EXAMPLE ANSWER: DO NOT USE ANY IF THEM BELOW FOR I DO NOT KNOW THE UNIT LENGTH OR SHAPE THE CONNECTED DOTS WOULD CREATE!!!

The two triangles could be similar due to the identical amount of units between each vertice. Furthermore, you could connect the units in a certain orientation, keeping the units in mind, and produce two identical triangles.

Or...

The two triangles could be similar due to the type of triangle. Each triangle has the potential to be a (right/scalene/isosceles/obtuse/acute, etc).
