Answer:
Looking at the first question, it's asking what best describes the probability of tossing a number less than 6 on a number cube that has 6 numbers. Impossible means that it will never land on it, for example asking what the probability of landing on 7 is. Unlikely is something that doesn't happen often. The best option that fits our scenario is option C, likely.
Looking at the second question, it's asking what the probability that the teacher chooses a girl in his class. There are 15 girls and a total of 27 students in the class so we take the probability by doing 15/27. We can narrow both the numerator and the denominator using 3 which gives us 5/9. Therefore, the best option that fits our scenario is option C, 5/9.
Finally, looking at the last question, it's asking what the theoretical probability that the coin will land on heads on the next toss. Theoretical probability doesn't consider how much times Murray tossed the coin, the only thing it cares about is what the actual probability of tossing a coin is. Therefore that makes it a 50% chance of landing on a heads and a 50% chance of landing on a tails. The best option that first our scenario is option B, 1/2.
Hope this helps! Let me know if you have any questions

What is the value of "b" in the following quadratic? (Make sure the equation is in
standard form: ax + bx +c= 0)
x^2 + 28 = -11x
Answer:
b = 11
Step-by-step explanation:
the standard form of a quadratic equation is ax² + bx + c = 0 ( a ≠ 0 )
given
x² + 28 = - 11x ( add 11x to both sides )
x² + 11x + 28 = 0 ← in standard form
with b = 11

The side AE and side CD are parallel to each other because they will never intersect to each other.
What is a regular polygon?A polygon is a two-dimensional geometric figure having a finite number of sides. Straight-line segments are linked end to end to make a closed shape on the sides or edges of a polygon. The vertices or corners are the spots where two line segments intersect, resulting in an angle.
As we know, the parallel lines never intersect to each other, they go infinitely without crossing each other.
As we can see in the figure (refer to the attached picture)
Line AE and CD are parallel to each.
Thus, the side AE and side CD are parallel to each other because they will never intersect to each other.

Answer:
The answer is below!
Step-by-step explanation:
If (1,2), and ( - 20,9) are two solutions of f(x) = mx
b. find m and b.
The function f(x) = mx + b is a linear function, and the values of m and b are -1/3 and 7/3, respectively
How to determine the values of m and b?The function is given as:
f(x) = mx + b
The solutions are (1,2) and (-20,9)
The above points mean that:
1 * m + b = 2
-20 * m + b = 9
This gives
m + b = 2
-20m + b = 9
Subtract both equations
m + 20m = 2 - 9
Evaluate the difference and sum
21m = -7
Divide both sides by 21
m = -1/3
Substitute m = -1/3 in m + b = 2
-1/3 + b = 2
Add 1/3 to both sides
b = 2 + 1/3
Evaluate
b = 7/3
Hence, the values of m and b are -1/3 and 7/3, respectively

[tex]\rule{50}{1}\large\textsf{\textbf{\underline{Answer and how to solve:-}}}\rule{50}{1}[/tex]
Before starting to solve, you should notice something - the
quadratic is not in its standard form!
We can easily fix it by adding [tex]\large\textit{11x}[/tex] on both sides:-
[tex]\large\text{$x^2+28-11x=0$}[/tex]
We can switch the order of 28 and -11x:-

Now, the quadratic is in its standard form, so we can get down to
finding the value of "c".
Remember, the standard form of a quadratic looks like so:-
[tex]\large\text{$ax^2+bx+c=0$}[/tex]Now we can just write our quadratic here:-
[tex]\large\text{$x^2-11x+28=0$}[/tex]Now, can you see what the value of "c" is?
An easy way to remember "c" in quadratics is:-
The "c" in quadratics is the constant.

Cones a and b are similar.
the surface area of cone a is 36cm2.
the surface area of cone b is 100cm2.
the volume of cone a is 162cm3.
work out the height,
h
, of cone a and the volume of cone b:
The height of cone A is 12 and the volume of cone B is 750
How to determine the height and the volume?The given parameters are:
Surface area of cone a is 36cm²Surface area of cone b is 100cm²Volume of cone a is 162cm³Both cones are similar.
The similarity ratio is represented as:
[tex](\frac{V_A}{V_B})^\frac 13 = (\frac{A_A}{A_B})^\frac 12 = \frac{h_A}{h_B}[/tex]
Where:
V represents volumeA represents surface areah represents heightRemove the height expression in the equation [tex](\frac{V_A}{V_B})^\frac 13 = (\frac{A_A}{A_B})^\frac 12 = \frac{h_A}{h_B}[/tex]
So, we have:
[tex](\frac{V_A}{V_B})^\frac 13 = (\frac{A_A}{A_B})^\frac 12[/tex]
This gives
[tex](\frac{162}{V_B})^\frac 13 = (\frac{36}{100})^\frac 12[/tex]
Evaluate the exponent of 1/2
[tex](\frac{162}{V_B})^\frac 13 = \frac{6}{10}[/tex]
Take the cube of both sides
[tex]\frac{162}{V_B} = \frac{216}{1000}[/tex]
Make VB the subject
[tex]V_B = \frac{162 * 1000}{216}[/tex]
Evaluate
[tex]V_B = 750[/tex]
Remove the area expression in the equation [tex](\frac{V_A}{V_B})^\frac 13 = (\frac{A_A}{A_B})^\frac 12 = \frac{h_A}{h_B}[/tex]
[tex](\frac{V_A}{V_B})^\frac 13 = \frac{h_A}{h_B}[/tex]
Substitute known values
[tex](\frac{162}{750})^\frac 13 = \frac{h_A}{20}[/tex]
Multiply both sides by 20
[tex]h_A = 20 *(\frac{162}{750})^\frac 13[/tex]
Evaluate
[tex]h_A= 12[/tex]
Hence, the height of cone A is 12 and the volume of cone B is 750

Answer:
The two cones are aligned on edge to edge so that the total volume of the hourglass becomes 2∗13πr2h
Step-by-step explanation:
a) When the sand has y units left in the upper cone the height of the cone becomes y, the radius remains 1cm.Now let's take the right triangle In the upper coneAnd by similar triangles property we found that the radius of the cone in which the amount of sand is left is y3 unitsNow the volume of the sand in the remaining part of the upper cone isπy32y which gives πy327Now if we apply the same similar triangle property with the cone in the below we find that the radius of the part it has filled up remains the same as y3unitsSo the volume it has filled is (3-y) from the top cone which says that the volume filled on the bottom cone has a height of (3-y)So therefore the volume of the frustum which it has filled up isπ3h(R2+r2+rR) {Is the volume of the frustum with two radii r and R with a height h}i.eπ3(3−y)(12+(y/3)2+(y/3))So now the total volume of the hourglass in terms of y is π3(3−y)(12+(y/3)2+(y/3))+πy327b) The next question tells us that when the height of the sand in the below cone reaches up a height of h centimetreswhich is exactly 3-y in the previous questionso substituting y = h-3 in the previous question we'll find the volume of the hourglass in terms of hπ(h−3)327+π3(6−h)(12+((h−3)/3)2+((h−3)/3)) .c) Total volume of the hourglass isV=V1+V2⇒3π4=πy327+π−π27(3−h)3Putting h=1We have the value of y as⇒3π4=π27y3+π+π278..............(1)⇒y=(54)13Differentiating the first equation with respect to t we have0=π9y2dydt+π9(3−h)2dhdtPutting values that dydt=−0.14inches/sec at h =1 and for ⇒y=(54)13We have0=π9(54)132∗(−0.14)+π922dhdt⇒0.1956π9=4π9dhdt⇒dhdt=0.19564⇒dhdt=0.0489
