The total number of sample space in this item is calculated by adding up all the number of students given. That is,
S = 600 + 400 + 300 + 200 = 1500
The probability is calculated with the equation below.
P = n / S
where P is the probability,
n is the number of sophomores, and
S is the total number of students
Substituting,
P = 400 / 1500 = 4/15
<em>ANSWER: 4/15</em>
Let, the integers = x,(x+1)
x*(x+1) = 56
x²+x = 56
x²+x-56 = 0
x²+8x-7x-56=0
x(x+8)-7(x+8)=0
x+8= 0 OR x-7=0
x = -8 OR x = 7
it would be -8 & -7 or 7 & 8
Answer:
The Y-intercept is 6
Step-by-step explanation:
a. 4/5 because
the equation to find slope is
y2-y1 divided by x2-x1
which is -5-(-1) divided by -2-3 which is -4/-5 which is 4/5.
