A, B and C

Answers

Answer:

a) Set up triangles where the hypotenuse is 16ft (the ladder) and one of the two edges are 1, 2, 3, 4, 5ft (the base of the ladder).  Use a^2 + b^2 = c^2 where a is the base length, c is the hypotenuse and b is the value you are trying to find.

Ex w/ 1ft base:

1^2 + b^2 = 16^2

1 + b^2 = 256

b^2 = 255

b = 15.97ft.

b) Simply take your answers from part a) and add 5.5ft (the height of the girl) to them.

Ex w/ 1ft base:

15.97ft + 5.5ft = 21.47ft

c) Using logic here think about it.  Let's take the 1ft base as the example.  Marissa standing on top of the ladder is 21.47ft.  That's clearly not high enough to reach the cat . . . but what happens if Marissa reaches upwards.  As long as her arms can reach roughly 1.53ft above her head she should be able to reach it.

Find the probability of rolling an odd number on a fair number cube and drawing a 7 of any suit from a standard deck of cards.

Answers

Answer:

A deck of cards contains RED cards numbered 1,2 and BLUE cards numbered ... Patricia will draw 8 cards from a standard 52-card deck with replacement. ... Outcome: any of the possible results of an experiment in probability. ... Correct answers:$\frac{7}{9}$7/9​​ ... Event A: rolling a 6-sided fair number cube and getting 1Step-by-step explanation:

The probability of rolling an odd number on a fair number cube and drawing a 7 of any suit from a standard deck of cards is 1/26.

To find the probability of rolling an odd number on a fair number cube and drawing a 7 of any suit from a standard deck of cards, we need to calculate the probabilities of each event and then multiply them together since the events are independent (the outcome of one event does not affect the outcome of the other event).

1. Probability of rolling an odd number on a fair number cube:

A fair number cube has 6 faces with numbers 1 through 6. Out of these, three numbers are odd: 1, 3, and 5. So, the probability of rolling an odd number is 3/6, which simplifies to 1/2.

2. Probability of drawing a 7 of any suit from a standard deck of cards:

A standard deck of cards has 52 cards. There are four 7s in the deck (one for each suit: hearts, diamonds, clubs, and spades). So, the probability of drawing a 7 is 4/52, which simplifies to 1/13.

Now, multiply the probabilities together:

Probability = (Probability of rolling an odd number) * (Probability of drawing a 7)

Probability = (1/2) * (1/13)

Probability = 1/26

Therefore, the probability of rolling an odd number on a fair number cube and drawing a 7 of any suit from a standard deck of cards is 1/26.
