Answer:
Step-by-step explanation:
y^2 - 3y + 12
It has 3 terms (y^2) and (-3y) and (12)...therefore, it is a trinomial.
The degree of a polynomial with 1 variable is the highest exponent...so it has a degree of 2. But if it had more then 1 variable, it would be different.
answer is : trinomial with a degree of 2
The polynomial y² – 3y + 12 is trinomial with a degree of 2. Therefore, option C is the correct answer.
The given polynomial is y² – 3y + 12.
What is polynomial?An expression of more than two algebraic terms, especially the sum of several terms that contain different powers of the same variable(s).
Here, the polynomial y² – 3y + 12 is trinomial with a degree of 2
Therefore, option C is the correct answer.

Step-by-step explanation:
3) In another game, there are 10 marbles in a box. 6 are red and 4 are blue. You
pull one marble from the box, don't put it back, and then pull another marble.
Calculate the following probabilities:
a) Pulling two reds.
b) Pulling two blues.
c) Pulling one of each.
Part (A)
We have 6 red and 4 blue marbles, so 6+4 = 10 total.
The probability of getting red is 6/10 since we have 6 red out of 10 total.
The probability of getting another red is 5/9 because we don't put the first marble back.
The probability of getting two reds in a row is (6/10)*(5/9) = 30/90 = 1/3
Answer: 1/3========================================================
Part (B)
4/10 represents the probability of getting blue on the first try
3/9 represents the probability of getting a blue marble on the second try
We don't put the marble back.
(4/10)*(3/9) = 12/90 = 4/30 is the probability of getting two blues in a row.
Answer: 4/30========================================================
Part (C)
Add up the results of parts (A) and (B)
1/3 + 4/30
10/30 + 4/30
(10+4)/30
14/30
7/15
The result 7/15 is the probability of either getting two reds OR getting two blues (pick one case only). This tells us that 7 out of 15 times we'll have this happen. This must mean the remaining 8 times will have two marbles of different colors.
So 8/15 is the probability of picking one marble of each color.
------
As an alternative, we could also consider it like this
(6/10)*(4/9) = 24/90 = 4/15
This represents the probability of picking red first, then blue next.
Similarly,
(4/10)*(6/9) = 24/90 = 4/15
represents the probability of picking blue first, then red next.
Therefore, 4/15+4/15 = 8/15 is the probability of getting one of each color.

Answer: 8/15The table shows the time a patient spends at the dentist and the amount of the bill.

There is a square parking lot at the grocery store. The diagonal of the parking lot measures 8√2 ft. Find the perimeter of the parking lot.
Answer:
[tex]32\:\mathrm{feet}[/tex]
Step-by-step explanation:
The square forms two 45-45-90 triangles, where the diagonal of the square is the hypotenuse of both these triangles. In all 45-45-90 triangles, the sides are in the ratio [tex]x:x:x\sqrt{2}[/tex], where [tex]x\sqrt{2}[/tex] is the hypotenuse of the triangle and [tex]x[/tex] represents each of the two other sides of the triangle (from the Pythagorean Theorem).
Thus, we know that [tex]8\sqrt{2}[/tex] represents the hypotenuse, which means that the side length must be [tex]8[/tex] feet. The perimeter is then [tex]4\cdot 8=\boxed{32\:\mathrm{feet}}[/tex]
Two different cross sections are taken parallel to the base of a three-dimensional figure. The two cross sections are the same shape, but are not congruent.
Which could be the three-dimensional figure? Select three options.
cone
cylinder
triangular prism
triangular pyramid
square pyramid
A. cone
D. triangular pyramid
E. square pyramid
(Look at the photo at the bottom.)
Step-by-step explanation:First, know what a cross section is. A cross section is the exposed shape or surface when a straight cut is made through a 3D figure. For example, if I make a cross section, or cut, through a sphere, the cross section will be a circle. The newly exposed surface is in the shape of a circle.
We want to know which 3D figures can make 2 different cross sections, parallel to the base, that are congruent. Congruent means same shape but different size. Parallel to the base means the cut is completely horizontal.
A cone is one, because no matter where you horizontally cut this, the cross section will always be a circle, but different sizes.A triangular pyramid is another, because no matter where you horizontally cut this, the cross section will always be a triangle, but different sizes.A square pyramid is another, because no matter where you horizontally cut this, the cross section will always be a square, but different sizes.Here's a photo of Edge incase you're doubtful.

(d) How many pounds of potting soil did Emmanuel buy last week?
Answer:
plz help me I beg you
Answer:
1.) Amount of potting soil purchased last week.
2) 2p + 4 = 28
3.) 12 lbs
Step-by-step explanation:
1.) The unknown information is what we intend to find out using the information given, which is the amount of potting soil Emmanuel bought last week.
2.)
Let amount of potting soil bought last week = p
Amount bought this week = 2p + 4
Since amount bought this week = 28
Hence, we have ;
28 = 2p + 4
28 - 4 = 2p
24 = 2p
p = 24 / 2
p = 12
Put the following equation of a line into slope-intercept form, simplifying all fractions.
9x+12y=-84
Answer:
y = (-3/4)x + 7
Step-by-step explanation:
Answer:
y = -3/4x - 7
Step-by-step explanation:
Slope Intercept form: y=mx + b where m = slope and b = intercept.
Isolate y.
9x + 12y = -84
-9x -9x (subtract 9x from both sides)
12y = -9x - 84
(divide by 12)
y = -9/12x - 7
(simplify fraction)
y = -3/4x - 7

1. Lily spent 4 times as much as her sister Sue. If the girls spent $24, how much did each girl spend?
Answer:
Lily spent $19.20, Sue spent $4.80. Make sure to include the units.
Step by Step:
Lets say Sue is X
4x+x=24
5x=24
x=24/5
x=4.8
So sue spent 4.8.
24-4.8=19.2
Lily spent 19.2
Check: 4(4.8)=19.2
19.2+4.8=24

Answer:
Percentage of china's population to world = 19.85 % (Approx.)
Step-by-step explanation:
Given:
Population of China shows in 2014 = 1.39 billion
Find:
Fraction of china's population to world
Percentage of china's population to world
Computation:
Approximately population of world = 7 billion
Fraction of china's population to world = 1.39 / 7
Percentage of china's population to world = [1.39 / 7]100
Percentage of china's population to world = [0.1985]100
Percentage of china's population to world = 19.85 % (Approx.)
