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.

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.
[tex]\frac{1}{13} * \frac{4}{51} = \frac{4}{663}[/tex]
Answer:
1/13

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

A quadratic equation of the form 0=ax2 bx c has a discriminant value of -16. how many real number solutions does the equation have?
The given quadratic equation has no real solutions.
Given quadratic equation is:
[tex]ax^2+bx+c=0[/tex]
What does the discriminant of a quadratic equation tell?The discriminant(D) of a quadratic equation tells about the nature of roots.
If [tex]D > 0[/tex], the roots of the quadratic equation will be real and distinct.
If [tex]D=0[/tex], the roots of the quadratic equation will be real and equal.
If [tex]D < 0[/tex], the roots of the quadratic equation will be imaginary.
Given that the quadratic [tex]ax^2+bx+c=0[/tex] has a discriminant value of -16.
[tex]D=-16 < 0[/tex]
So, the roots of the given quadratic equation will be imaginary.
So, the given quadratic equation has zero real solutions.
Hence, the given quadratic equation has no real solutions.

Step-by-step explanation:
You're trying to find m which is a variable for measurement for the "D" angle.
Info Given:
20.5 for angle C
Unknown for angle D
Both angles are Complementary.
_____________________________________________
I have 2 answers for this (The question was stated unclearly so I have 2 interpretations of this)
1st Answer:
If you're asking to solve for M but the C and D angles add up to 90 then do
90 - 20.5 = 69.5
2nd Answer:
We know that both angles are complementary which are 90-degree angles.
If we combine them then the angles add up to 180.
So C and D add up to form a Supplementary Angle.
20.5+69.5 + m = 180
Then M could possibly be 90.

Step-by-step explanation:
So let's actually make a readable expression first.

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]
