You flip an unfairly weighted coin 4 times. If the probability of getting a tail is 0. 38.
What is the probability you will get at most 2 tails?
work needed
Answer:
0.84306608
Step-by-step explanation:
The probability of an event, e, occurring exactly r times over n trials follows the formula
(n combination r) * p^r * q ^ (n-r)
with p being the probability the event will occur and q being the probability the event will not occur.
I assume you have a calculator/can find one online that can do combinations.
Here, we want to figure out if you get:
- 0 tails
- 1 tail
- 2 tails
If you get 3 or 4 tails, we are getting more than the 2 tails desired
For 0 tails:
- p is the probability a tail will occur = 0.38
- we want it to occur 0 times, so r = 0
- q is (1-p) = 1- 0.38 = 0.62
- we have 4 trials, as we flip it 4 times
(n combination r) * p^r * q ^ (n-r) = (4 combination 0) * (0.38) ^0 * (0.62) ^(4-0) = 1 * (0.38) ^0 * (0.62) ^(4-0) = 0.14776336
For 1 tail:
- p = 0.38, q = 0.62 as with 0 tails
- r = 1, n = 4
(n combination r) * p^r * q ^ (n-r) = (4 combination 1) * (0.38) ^1 * (0.62) ^(4-1) = 4* (0.38) ^1 * (0.62) ^(4-1) = 0.36225856
For 2 tails:
- p = 0.38, q = 0.62 as with 0 tails
- r = 2, n = 4
(n combination r) * p^r * q ^ (n-r) = (4 combination 2) * (0.38) ^1 * (0.62) ^(4-2) = 6* (0.38) ^2 * (0.62) ^(4-2) = 0.33304416
add our 3 probabilities together
0.33304416 + 0.36225856 + 0.14776336 = 0.84306608 as our answer

Answer:
A = 35
B = 100
C = 25
Step-by-step explanation:
All interior angles in a triangle add up to 180 degrees.
x + 65 + x + 25 = 180
2x + 110 = 180
2x = 70
x = 35
Answer (1):
A=45 B=110
Step-by-step explanation (1):
So the inner degrees has to equal 180. So you would do this:
[tex](x+65)+x+25=180\\2x+90=180\\2x=90\\x=45[/tex]
Now substitute 45 for x and check.
[tex]45+65=110\\110+45+25= < ABC\\180= < ABC[/tex]
Answer (2):
126 degrees.
Step-by-step (2):
Like I said before, the inner degrees has to equal 180. We would write another equation. By the way, the red square is for 90 degrees.
[tex](5x-6)+3x+90=180\\8x+84=180\\96=8x\\x=12[/tex]
Now substitute 12 for x.
Also to find the anterior angle, we would add the 90 and the 3x[tex]3(12)=36\\90+36=126\\126+(5x-6)=180\\120+5x=180\\180=180[/tex]

Under an enlargement transformation point A(1,-4)is mapped onto A¹(2,5)with scale factor 3 find the center of enlargement
Answer:
(1/2, -8 1/2)
Step-by-step explanation:
The enlargement transformation maps point A to one that is 3 times as far from the center of enlargement. If the center is C, then we have the relation ...
(A' -C) = 3(A -C)
__
Solving for C gives ...
A' -C = 3A -3C
2C = 3A -A' . . . . . . . add 3C-A'
C = (3A -A')/2
Filling in the given coordinates for A and A', we find the center of enlargement to be ...
C = (3(1, -4) -(2, 5))/2 = (3 -2, -12 -5)/2 = (1, -17)/2
C = (1/2, -8 1/2)
The center of enlargement is (1/2, -8 1/2).

A. 9\sqrt(3)
B. 24
C. 72
D. 8\sqrt(3)
Answer: Below
Step-by-step explanation:
So let's actually make a readable expression first.
[tex]\frac{8\sqrt{3} }{\sqrt{5} }[/tex]
We first want to rationalize denominators (turning the denominator into an integer),so multiply both the numerator and denominator by sqrt(5). This method is called the big one, and doesn't change an expression since sqrt(5)/sqrt(5) = 1.
[tex]\frac{8\sqrt{3} }{\sqrt{5} } * \frac{\sqrt{5} }{\sqrt{5} } = \frac{8\sqrt{3}\sqrt{5} }{5} = \frac{8\sqrt{15} }{5 }[/tex]

A card is drawn from a standard deck, put aside, and then another card is drawn. What is the probability that the first card is a king and that the second card is a queen?
FRACTION FORM
Answer:
4/663
Step-by-step explanation:
Since the first card is set aside after being drawn, this is dependent probability.
There are 4 kings in 1 deck of 52 cards.
Therefore the probability of choosing a king is 4/52 = 1/13.
But after choosing 1 card from the deck, there are now 51 cards in the deck. There are 4 queens in the deck of 51 cards. Therefore the probability of choosing a queen is 4/51.
To determine the probability of choosing both, multiply the 2 probabilities.

what is the length of AD and find the measure of angle CAB
Answer:
AD = 44 and angle CAB = 90 degrees
Step-by-step explanation:
since the shape is a rectangle, all corner angles must be 90 degrees. so CAB is also 90 degrees.
the length of half of BC is 22, so the full length of BC is 44. using symmetry, AD should also be 44.
