Answer:
Sample: Kevin should have used an open circle on 1, not a closed circle. The closed circle means that 1 is included in the solution set, but the inequality is x > 1, so 1 is not part of the solution.
Mistake done by Kelvin is he used closed circle at 1 where inequality x > 1 which excludes 1.
What is open and closed circles?
" Closed circle represents that the value is included in the given range while that of open circle represents given number is not included."
According to the question,
Graph of inequality x > 1 represents all values greater 1 excluding 1.
Number line represents -3 to 5.
A closed circle at 1 means 1 is included.
As per the condition of inequality x > 1 , 1 is excluded while in closed circle 1 is included both are contradictory conditions.
Hence, mistake done by Kelvin is he used closed circle at 1 where inequality x > 1 which excludes 1.

Victoria uses
3/16
cup of flavored syrup to make an Italian soda. She has 2 cups of flavored syrup left. How many Italian sodas can she make?
A.
9 3/8
B.
10 2/3
C.
11 1/4
D.
12 1/2
Answer:
B. or 10 2/3
Step-by-step explanation: Because if she had only 2 cups left then 1 cup can make 5 drinks so 10 then the rest would be a fraction.
She can make 32/3 of Italian sodas with 2 cups of flavored syrup.
What is a fraction?
A fraction is written in the form of p/q, where q ≠ 0.
Fractions are of two types they are proper fractions in which the numerator is smaller than the denominator and improper fractions where the numerator is greater than the denominator.
Given, Victoria uses 3/16 cups of flavored syrup to make an Italian soda.
Assume that 3/16th of x is 1.
∴ (3/16)x = 1.
3x/16 = 1.
3x = 16.
x = 16/3,
Now from 2 cups of flavored syrup, we can make 2x of Italian soda.
Which is (16×2)/3.
= 32/3

An aquarium is in the shape of a rectangular prism. The area of the base of the aquarium is 250 square inches. Which is the volume of the aquarium? Pleaseeee helpppp
Step-by-step explanation:
It is given that,
An aquarium is in the shape of a rectangular prism. The area of the base of the aquarium is 250 square inches.
We need to find the volume of the aquarium.
The formula for the volume of the rectangular prism is given by :
V = lbh
Where, l is length, b is width and h is height
Let the height of the prism is h inches. So,
V = A × h (As Area, A = lb)
V = 250× h
= (250h) inch³
By substituting the value of h, we can find its volume.
Hence, the volume of the aquarium is (250h) inch³.

what is the answer to x - 8 < -2
Answer:
X < 6
Step-by-step explanation:
Add 8 to both sides
x < 6
Answer:
X<6
Step-by-step explanation:
x-8<-2
So first off, you want to get X by itself. To do that you have to do the opposite of what the number is. If the number is negative you add it. If the number is positive, you subtract it. What you do on one side, you do on both.
x-8<-2
+8 +8
X<-2+8
Next, You need to add alike terms.

Step-by-step explanation:
both of those equations that are in the system are lines
first line it has a y-intercept at (0, -4) and a slope -1/2 so you can use that to
find another point ( 2 ,-5)
Since the equation has ≥ DRAW a solid line trough points (0, -4) and (2,-5)
Now highligt above the line since (0,0) cheks for the equation
second line goes troughh the points (0,1) because of y-intercept and point (1,2) because the slope is m=1
draw a solid line trough those points and highlight under the line
the intersection of the 2 highlighted ares is your solution

A random two digit number (10-99) is drawn. Find each probability
1. p(32)
2. p(odd number)
3. p(a multiple of 5)
My teacher gave an assignment on this and didn't even teach how to do it.
Given that two digit numbers are used and one digit is drawn randomly.
Sample space = {10,11,...99}
n(S) = 90
32 is only one number favorable
Hence P(32) = 1/90
----------------------------
Odd numbers are exactly 45.
Hence prob (odd number) = 45/90 = 1/2
-------------------------------------
Multiples of 5 are 10,15,.....95
There are exactly 18 numbers.
Hence P(a multiple of 5) = 18/90 =1/5
