from the Deck of 52 cards is drawn at a random . what is the probability of a face card or ace ?
Answers
Step-by-step explanation:
Given that,
Total no. of cards = 52 (Total no. of outcomes)
There are 12 face cards. No of favorable outcomes = 12
P(E) = favorable outcome/total no of outcomes
So,
[tex]P(F)=\dfrac{12}{52}\\\\=\dfrac{3}{13}[/tex]
There is 4 ace in a deck of 52 cards.
[tex]P(A)=\dfrac{4}{52}\\\\=\dfrac{1}{13}[/tex]
Hence, this is the required solution.
A triangle has an area of 230.86 square inches. The height of the triangle is 23.8 inches. What is the length of the base of the triangle?
I'll give brainlist!! Pls help
Answers
Answer:
Length of the base of the triangle = 19.37 inch (Approx.)
Step-by-step explanation:
Given:
Area of given triangle = 230.56 square inches
Height of the triangle = 23.8 inches
Find:
Length of the base of the triangle
Computation:
Area of triangle = (1/2)(b)(h)
Area of given triangle = (1/2)(Length of the base of the triangle)(Height of the triangle)
230.56 = (1/2)(Length of the base of the triangle)(23.8)
461.12 = (Length of the base of the triangle)(23.8)
(Length of the base of the triangle)(23.8) = 461.12
Length of the base of the triangle = 19.37 inch (Approx.)
In a quiz contest, Mary answers 90% of the questions correctly without any additional clues from the quiz coordinator. The randomly generated numbers below simulate this situation.
The numbers 0 to 8 represent questions answered correctly without additional clues, and the number 9 represents questions that needed additional clues.
44 51 99 66 23
68 72 20 20 59
50 89 39 36 20
90 13 51 47 92

40 44 30 95 22
99 10 55 10 35
36 78 92 37 96
The estimated probability that it would take at least three questions for Mary to need additional clues is (_____)
The estimated probability that Mary needed additional clues to answer two consecutive questions is (_____)
Answers
To solve this problem, we should note that there are:
total questions = 100
questions answered correctly = 90
questions that needed additional clues = 10
1. The first question is to find the probability that in the third question, Mary would need additional clue. Therefore this implies that in the first and second questions, Mary would answer it correctly. Therefore:
Probability = (question 1 answered correctly) * (question 2 answered correctly) * (question 3 needed clue)
Probability = (90/100)*(89/99)*(10/98)
Probability = 0.08256 = 8.26%
2. The second question finds for the probability that two consecutive needs additional clue, therefore:
Probability = (question 1 needed clue) * (question 2 needed clue)
Probability = (10/100)*(9/99)
Probability = 9.1*10^-3 = 0.91%
Answer:
1. The estimated probability that it would take at least three questions for Mary to need additional clues is 0.24
2. The estimated probability that Mary needed additional clues to answer two consecutive questions is 0.06

What is the speed of a car that traveled a
total of 300 kilometers north in 2 hours?
Answers
Speed = Distance/Time
So, speed
= 300 km/2h
= 150km/h
= (150 × 1000m) / 3600s
= 150000m/3600s
= 41.66m/s [approximately]
Julio's family traveled 3 8 of the distance to his aunt's house on Saturday. They traveled 3 5 of the remaining distance on Sunday. What fraction of the total distance to his aunt's house was traveled on Sunday?
Answers
Answer: [tex]\dfrac{3}{8}[/tex]
Step-by-step explanation:
Given
Julio traveled [tex]\frac{3}{8}[/tex] of distance to his aunt's house on Saturday
they have traveled [tex]\frac{3}{5}[/tex] of the remaining distance on Sunday
suppose the total distance is [tex]x[/tex]
Distance traveled on Saturday
[tex]\dfrac{3x}{8}[/tex]
Remaining distance is
[tex]x-\dfrac{3x}{8}=\dfrac{5x}{8}[/tex]
Distance traveled on Sunday
[tex]\Rightarrow \dfrac{3}{5}\times \dfrac{5x}{8}=\dfrac{3x}{8}[/tex]
The fraction of distance traveled on Sunday is
[tex]\Rightarrow \dfrac{\frac{3x}{8}}{x}=\dfrac{3}{8}[/tex]

Answer:
10.7
Step-by-step explanation:
To find x we have to basically do pythagoream theorem twice. Both the traingles share the same long side. The find the long side of the top traingle do, [tex]a^{2} +16^{2} =25^{2}[/tex], and we find the long side to be [tex]\sqrt{369}[/tex]. Using this we now plug it into the pythagoream theorem for the bottom triangle. [tex]\sqrt{369} ^{2} +x^{2} =22^{2}[/tex], and doing this out we find that x=[tex]\sqrt{115}[/tex] or about 10.7.
