Answer:
P(X = 0) = 0.25
P(X = 1) = 0.75
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
The probability distribution of X.
3 red balls out of 4, one picked, so we can have either 0 red balls or 1 red ball. The probability disitribution is the probability of each outcome.


The ratio of change in angular position to change in time is defined as the angular velocity. Thus, the slope of an angular position versus time graph gives the angular velocity of the <span>object being graphed.
The rank of the given graphs can be written as follow,positive graphs are listed first.
The line B is the line with the greater positive slope.
</span><span>The line B is the line with positive slope but is less than the slope of line B.
</span><span>The lines A,t ,and F are the lines with the zero slope.
</span>The lines D and E are parallel to each other and have same negative slope.<span />
Answer: a = 2,84
Step-by-step explanation:
34(4a + 12) = 21 a =
136a + 408 = 21
136a = -408 + 21
136a = - 387
a = <u>- 387 </u>
136
a = - 2,84
This isn’t easy due to fractions but you just need to find a common denominator, what goes into 9 evenly and also goes into 4 evenly. 36 works and it is the lowest common denominator. What number multiplied by 9 gets you 36? (36/9) 4. So Emma uses 4/36ths of a gallon of gas to get 9/36ths of the way to work. So you take (4/36) or .25 and multiply that by 9 to get...
2.25 trips
