Answer:
Probability that event will have both red marbles will be 2.3% or 0.023.
Step-by-step explanation:
Given:
Total red marbles=5
Total blue marbles=25
Total number of marbles =30
To Find:
The probability that both are red without replacement of marbles.
Solution:
Now
Total sample space is 30 and total red marbles are 5
For a event that getting red marble probability is ,
=Total red marbles /total marbles.
=5/30
=1/6
So probability if getting red marble is 1/6
<em>Now for second chance there will be 4 red marbles remaining and 29 total marbles so,</em>
In second chance probability if getting red marble will be
=total red marbles present/total marbles remaining
=4/29
Now ,
The required probability will be getting both at a time
i.e probability getting red AND red marble so here AND operator which means multiple both the probability.
Probability both will have red =1/6*4/29
=4/(29*6)=2/(29*3)
=0.022988
=0.023
=2.3 %
The answer is 0.003, because the two "00" in front of the three represent, tenths and hundredths, and the 3 is in the thousandths place<span />
Just substitute t=t-2 in given function.
so, p(t-2)=4(t-2)-5
Answer:
Step-by-step explanation:
Since we are given a point and a slope, we should use the point-slope equation.
where <em>m</em> is the slope and (x₁, y₁) is the point the line passes through.
We are given the slope of 1/2 and the point (4, -3). Therefore:
Substitute the values into the formula.
Distribute the 1/2. Multiply each term inside the parentheses by 1/2.
We want to the equation of the line in slope-intercept form or y=mx+b. We need to isolate y. 3 is being added and the inverse of addition is subtraction. Subtract 3 from both sides of the equation.
The equation of the line is <u>y=1/2x-5</u>
It is not possible to form *any* triangle from the lengths 2, 4, and 7. The two short sides don't add to a length at least as long as the long side.
3. The missing side is given by the Pythagorean theorem:
√((6 in)^2 + (12 in)^2) = 6√5 in ≈ 13.416 in
