The discriminant is : (1)^2 + (-4)*(-3)*(2) = 1+24 = 25
Answer:
The Explanation is below with attachment.
Step-by-step explanation:
For the line y = 2x - 5
For Drawing a line on a graph we require minimum two points, but we will plot three points.
Here you can take any random value for X so that the corresponding Y value you will get.
So, put x = 0, in the equation we will get

Similarly,
Put x = 1 we will get,

Again,
Put x = -1 we will get,

Now we have three points say point A (0,-5)), point B (1.-3) and point C (-1,-7)
See the graph below
Answer:
225 students scored 65 or better and 75 students scored 88 or better.
Step-by-step explanation:
We are given that The five-number summary for the scores of 300 nursing students are given :
Minimum = 40

Median = 82

Maximum = 100
is the first quartile and is the median of the lower half of the data set. 25% of the numbers in the data set lie below
and about 75% lie above
.
is the third quartile and is the median of the upper half of the data set. 75% of the numbers in the data set lie below
and about 25% lie above 
i) .About how many students scored 65 or better?

Since we know that 75% lie above
.
So, Number of students scored 65 or better = 
ii)About how many students scored 88 or better?

Since we know that 25% lie above
So, Number of students scored 88 or better = 
Hence 225 students scored 65 or better and 75 students scored 88 or better.

A cube with unit edges of length

has volume.

The number of unit cubes that can go into the prism is

Answer:
a) Least (V):69 Greatest (V):84
b) 74 78 79 82 84 are equally the higher frequency so we go with the lower value (V): 74 which is also the mode and modal.
