The probability of the first one didn't do homework s 4/7,
the second is 3/6,
the third is 2/5,
Multiple all of them together
4/7*3/6*2/5=0.1143 or 11.43%
Answer:
0.1143 or 11.43%
6x^4 + 3x^3 - 39x^2 - 15x
Answer & Step-by-step explanation:
These triangles are similar. This means that they are going to have the same ratios within their different sides.
AC and CE already have measurements so we are going to find the ratio between them. We can do this by dividing 21 by 7.
21 / 7 = 3
So, since the ratio between AC and CE is 3, then the rest of the triangle has a ratio of 3 with the other triangle.
So, let's set up an equation so we can find the value of x.
21/7 = (20 - x)/x
Cross multiply.
21x = 140 - 7x
Add 7x to both sides of the equation.
28x = 140
Divide 28 from 140.
x = 5
Now that we have the value of x, then we can find the measurement of CD.
The measurement of CD is 5.
Answer:
10 cm
Step-by-step explanation:
3.75 / 1.5 = 2.5
2.5 x 4= 10
There are only 4 Kings in a standard deck of 52 poker cards, being the King of Spades, Clubs, Diamonds and Hearts. So the probability of drawing a king from the cards is 4/52 = 1/13.and it is the same for the ace so together they’d be 8/52 or 2/13.....hope that helps
