Answer:
We have a 52 card deck:
a. Find the probability that both cards are clubs.
The probability of drawing a club will be equal to the quotient between the number of clubs in the deck divided by the total number of cards in the deck.
We initially have 13 clubs and 52 cards, then the probability of drawing a club in the first draw is:
p1 = 13/52.
Now the probability of drawing a club in the second draw will be:
p2 = 12/51
Where each number is decreased by one because we already drew a card, and that card was a club.
Then the probability of both events happening will be equal to the product of the individual probabilities:
P = p1*p2 = (13/52)*( 12/51) = 0.059
b. Find the probability that the first card is a spade and the second is a club.
Same as before, the probability of first drawing a spade is:
p1 = 13/52
And the probability of drawing a club in the second draw will be:
p2 = 13/51
This case differs from the prior one because for the second draw we have 13 clubs in the deck, and as we already drew one card (that was not a club) the total number of cards in the deck is 51.
Now the joint probability will be:
P = p1*p2 = (13/52)*(13/51) = 0.064

200z + 50 = 8000 solve this problem
Answer:
39.75
Step-by-step explanation:
First, subtract 50 from both sides
200z + 50 - 50 = 8000 - 50
200z = 7950
Then isolate the variable by dividing both sides by 200
200z/200 = 7950/200
z=39.75
A rectangular garden is divided into four sections. Some dimensions are shown in the diagram, and the distance from
point A to point Cis 16 ft.
12 it

15 ft
What is the distance from point A to point B in feet?
A. 8ft B.7ft c.9ft D.6ft
Answer:9 ft
Step-by-step explanation:
The requried measure of the AB is given as 7ft. Option B is correct.
What are Pythagorean triplets?In a right-angled triangle, its sides, such as hypotenuse, and perpendicular, and the base is Pythagorean triplets.
Here,
From the diagram, applying Pythagoras' theorem to the right rectangle,
BC² = 15² - 12²
BC² = 81
BC = 9
Now,
AC = 16
AB + BC = 16
AB + 9 = 16
AB = 7 ft
Thus, the requried measure of the AB is given as 7ft. Option B is correct.

the geometric mean (altitude) theorem
the geometric mean (leg) theorem
the right triangle altitude theorem
the SSS theorem
Answer:
C: the right triangle altitude theorem
Step-by-step explanation:
In proof of the Pythagorean theorem using similarity, the right triangle altitude theorem allows us to state that the triangles are similar.
What is geometric mean(altitude) theorem?We know that the geometric mean (altitude) theorem states that the altitude is equal to the geometric mean of the two segments.
We know that the geometric mean (leg) theorem states that a leg is the geometric mean between the hypotenuse and the leg's projection on it in every right triangle.
We know that the right triangle altitude theorem states that If we draw an altitude in a right triangle from the vertex which contains the right angle to the opposite side, the triangles on both sides of the altitude are congruent, and the entire triangle is congruent as a result.
We know that the SSS theorem If the three sides of one triangle are equal to the three sides of the other, then the two triangles are congruent.
How to tackle the problem?Here, we have to find the specific theorem which demonstrates the equality of proportionate values in the Pythagorean theorem. From the above theorems, we can conclude that our required theorem is the right triangle altitude theorem.
Therefore In proof of the Pythagorean theorem using similarity, the right triangle altitude theorem allows us to state that the triangles are similar. So, option C is correct.

Dennis wants to save $189 for a trip to an amusement park. He sets aside $14 of his allowance at the end of each week. How many weeks will it take him to save enough money for the whole trip?
Answer:
x = 13.5 weeks
Step-by-step explanation:
Since he wants to save $189 in total, that will be on one side of the equation by itself. You have to set this up in a y = mx + b equation. The y will be the 189. Since the word "each" goes with the number 14, that will be your m value. There is no value for b.
189 = 14x is your equation. The only step after setting up the equation is to divide 189 by 14. This gives you 13.5. Dennis will have to save up for 13.5 weeks.
