When the deck is fresh, it has 52 cards, and 4 of them are fives.
The probability of picking a five is ( 4 / 52 ).
Now the deck has 51 cards in it, and 48 of them are not fives.
The probability of picking a not-five is ( 48 / 51 ).
The probability of both successes in order is
( 4/52 ) x ( 48 / 51 ) = 7.24 % (rounded)
I have no idea which formula to use. Let me know if my answer is wrong.
Answer:
D. 4 real roots and 0 complex roots
Step-by-step explanation:
If I assume that the function you are saying is
There should be up to "4 roots," there can't be more or less than 4 total solutions. First, we need to check how many sign changes are there in this function. There are 3 positive real roots. Now lets check for negative roots.
There are is only 1 negative real root. Since we basically have 4 real roots, and the max is 4. There should be 4 real roots and 0 complex roots.
Answer:
x= 15
Step-by-step explanation:
Since this is an isosceles triangle, the other angle is also 5x-6
The sum of the angles of a triangle is 180
42+ 5x-6 + 5x-6 = 180
Combine like terms
10x+30 =180
Subtract 30 from each side
10x+30-30 = 180-30
10x = 150
Divide by 10
10x/10 = 150/10
x= 15
Answer:
Right
Step-by-step explanation:
The square in the left corner represents a 90° angle, which is a right angle, indicating that this triangle is a <u>right</u> triangle.
Answer:
Step-by-step explanation:
(-0.5-0.5)/(3+ 3) = 1/6
y - 0.5 = 1/6(x + 3)
y - 0.5 = 1/6x + 0.5
y = 1/6x + 1
