Answer:
3/12 = 1/4
Step-by-step explanation:
There are 12 marbles in the bag. If the marble drawn at random is red, it is one of the 3 red marbles.
The probability is "3 out of 12" = 3/12 which simplifies to 1/4.
Answer:
Step-by-step explanation:
10 x 3 = $30
10 x 4 = $12
$30 + $12 = $42 in think thats the answer i havent been to school in a while
Part A
Fraction of peach 2/5
Total = 200
number of students that pick peach as their favorite fruits

Part B
number of students that pick orange as their favorite fruits

number of students that pick plum as their favorite fruits

There are 55 more students that chose orange rather than plum.
240 homes in the county are between $175,000 and $225,000.
The image attached is associated with this question and m in it refers to the mean value which is $225000 here and d refers to the standard deviation which is $25000 here.
Now since m= $225000
and $175000= $225000-$50000= $225000-(2* $25000)= m-2d
Thus, as per the image area covered between m and m-2d= $225000
and $175000 is (34%+14%)of 500 homes= 68% of 500= 240 homes, is the answer.
A random variable X is said to follow a normal distribution if its parameters are mean and standard deviation. Every other distribution can be reduced to a normal distribution.
