Answer:
0.025 = 2.5% probability that a given class period runs between 51.5 and 51.75 minutes.
Step-by-step explanation:
An uniform probability is a case of probability in which each outcome is equally as likely.
For this situation, we have a lower limit of the distribution that we call a and an upper limit that we call b.
The probability that we find a value X lower than x is between c and d is given by the following formula

For this problem, we have that:
. So


0.025 = 2.5% probability that a given class period runs between 51.5 and 51.75 minutes.
7x - 3y = 4 => 7x = 3y + 4 => x = (3y + 4) / 7 2x - 4y = 1 => 2x = 4y + 1 => x = (4y + 1) / 2
=> (3y + 4) / 7 = (4y + 1) / 2 (3y + 4) * 2 = (4y +1) * 7 6y + 8 = 28y + 7 22y = 1 Y = 1/22 =>you can substitute y for the system of equations and find x
Answer:
the cost of the blueberry packing be $2.75 and the cost of the strawberry topping be $1.57
Step-by-step explanation:
The computation is shown below:
Let us assume the blueberry topping be x
And, the strawberry topping be y
Now as per the question
8x = $22
Divide by 2 to the both sides
4x = $11
x = $11 ÷ 4
= $2.75
And,
4x + 7y = $22
Now put the x value in the above equation
4 × (11 ÷ 4) + 7y = $22
11 + 7y = $22
7y = $22 - $11
7y = $11
y = $11 ÷ 7
= $1.57
Hence, the cost of the blueberry packing be $2.75 and the cost of the strawberry topping be $1.57
