The probability of rolling two number cubes whose numbers match is 6/36
Where does the number 36 come from?
Explain your thinking.
Answers
Answer:
The 36 is the total number of choices possible. Two cubes are rolled. If a 1 is rolled on one cube, there are 6 possible choices on the other cube (1, 2, 3, 4, 5, 6). If a 2 is rolled on one cube, there are 6 possible choices on the other cube (1, 2, 3, 4, 5, 6). After doing this for all 6 numbers on the first cube, you find that there are 6+6+6+6+6+6 or 6*6 possible choices. 6*6 is 36, so that is where the 36 is from. You can also use the Fundamental Counting Principle.

Part B: Is the vertex of the graph of f(x) going to be a maximum or a minimum? What are the coordinates of the vertex? Justify your answers and show your work. (3 points)
Part C: What are the steps you would use to graph f(x)? Justify that you can use the answers obtained in Part A and Part B to draw the graph. (5 points)
Answers
Answer:
A) x-intercepts are (0.6, 0) and (-1, 0)
B) vertex is (-0.2, -3.2)
C) see attached
Step-by-step explanation:
Part A
Given function: [tex]f(x)=5x^2+2x-3[/tex]
The x-intercepts are when f(x) = 0
[tex]\implies 5x^2+2x-3=0[/tex]
To factor, find two numbers that multiply to -15 and sum to 2: 5 and -3
Rewrite the middle term of the quadratic as the sum of these number:
[tex]\implies 5x^2+5x-3x-3=0[/tex]
Factorize the first two terms and the last two terms separately:
[tex]\implies 5x(x+1)-3(x+1)=0[/tex]
Factor out the common term [tex](x+1)[/tex]:
[tex]\implies (5x-3)(x+1)=0[/tex]
[tex]\implies (5x-3)=0\implies x=\dfrac35=0.6[/tex]
[tex]\implies (x+1)=0 \implies x=-1[/tex]
Therefore, the x-intercepts are (0.6, 0) and (-1, 0)
Part B
As the leading coefficient of the quadratic is positive, the parabola will open upwards. This means that the vertex will be a minimum point.
The x-coordinate of the vertex is the midpoint of the zeros.
[tex]\sf midpoint=\dfrac{-1+0.6}{2}=-0.2[/tex]
To find the y-coordinate of the vertex, substitute the found value of x into the given equation:
[tex]f(-0.2)=5(-0.2)^2+2(-0.2)-3=-3.2[/tex]
Therefore, the vertex is (-0.2, -3.2)
Part C
Plot the zeros and the vertex.
The axis of symmetry is the x value of the vertex, so ensure that the graph is symmetrical about x = -0.2.

Answers
The number of students those who will most likely have their preference to do their classwork online is 238 out of 350
What is the probability?The Probability in mathematics is the possibility of an event in time. In simple words, how many times that incident is happening in any given time interval.
According to the question statement:
A teacher surveys a random group of students about their preference for doing classwork online or on paper.
17 preferred online and 8 preferred on paper.
To find the number of students who will most likely have their preference to do their classwork online:
We will apply the concept of probability.
Probability(Event) = Favorable Outcomes/Total Outcomes
For the survey,
probability of students preferring online mode of classwork is = 17 /(17+8)
= 17/25
= 0.68
Now if we consider a group of 350 students and probability of students preferring online mode of classwork as 0.68
Let m be the number of students preferring online mode of classwork.
m / 350 = 17/25
m / 350 = 0.68
m = 350 x 0.68
m = 238
Therefore, the number of students are 238.

Base two iss 0.5 times the length of base one.
Base two = (12.5 x 0.5) ft = 6.25 ft
height = 10 ft
Area of trapezoid ground = 1/2 (sum of the kengths of the parallel sides) x height
= 1/2 (12.5 + 6.25) x 10

You make a cylindrical glass with an open top in industrial technology class. What is the surface area of the outside of the glass? Round your answer to the nearest hundredth, if necessary.
Answers
Answer:
4247.4 cm^2 after rounding to the nearest tenth
or 4247.43 cm^2 after rounding to the nearest hundredth
Step-by-step explanation:
the surface area can be split into 3 parts, the top, bottom, and side
the top and bottom areas are pretty easy, it's just the area of a circle
A = pi*13^2, which is 169pi for one circle, or 338pi for two
now, imagine the middle being unwrapped into a rectangle. the height of this rectangle is 39cm, and the length is just the circumference of the top/bottom circle, which is 2*pi*13, or 26pi cm
area is base*height, so 1014pi
add the two parts up (1014pi+338pi) to get 1352 pi, or about 4247.433
round to the nearest tenth to get 4247.4 cm^2
round to the nearest hundreth to get 4247.43 cm^2

Answers
Using a Ratio to solve
If we have a ratio of 7/12 odd cards to total cards she can expect to pull out 7 odds in her 12 cards. Now we will use this ratio out of 96 cards. If we have 96 cards with a 7/12 ratio we will divide 96 by 12 which is 8. Now we use our 8 and will multiply it by 7 which is our odd cards. Our total number of odds pulled out of 96 cards will be 56 out of 96.

this gives:
(2, 14) (4, 18) (6, 22) (8, 26) and (10, 30)
b) like above this time, we would need to multiply the original by 7
this gives:

c) base charge should be the charge they need to pay to rent the canoe, to add this in, we add 2 to the cost per hour
this gives:
(1, 9) (2, 11) (3, 13) (4, 15) (5, 17)

Add those which is your sum.
28+21.8+21.1+19+15.5=105.4
