Answer:
the numbers on an 8-sided die are 1, 2, 3, 4, 5, 6, 7, and 8
2, 3, 5, and 7 are prime numbers
half the numbers are prime
you should roll a prime number half of the time (theoretically)
if you roll the die 100 times, you (theoretically) should get a prime number 50 times, which is half of the time

(8, -56)
(-5,8)
(-9, -23)
(4, 19)
Answer:
(-5,8)
Step-by-step explanation:
The given equation y = -3x - 7 holds true for the ordered pair, so (-5, 8) is a solution. Thus, option third is correct.
To determine whether each ordered pair is a solution to the equation y = -3x - 7, we substitute the x and y values into the equation and check if it holds true.
For the ordered pair (8, -56):
y = -3x - 7
-56 = -3(8) - 7
-56 = -24 - 7
-56 = -31
The equation does not hold true for this ordered pair, so (8, -56) is not a solution.
For the ordered pair (-5, 8):
y = -3x - 7
8 = -3(-5) - 7
8 = 15 - 7
8 = 8
The equation holds true for this ordered pair, so (-5, 8) is a solution.
For the ordered pair (-9, -23):
y = -3x - 7
-23 = -3(-9) - 7
-23 = 27 - 7
-23 = 20
The equation does not hold true for this ordered pair, so (-9, -23) is not a solution.
For the ordered pair (4, 19):
y = -3x - 7
19 = -3(4) - 7
19 = -12 - 7
19 = -19
The equation does not hold true for this ordered pair, so (4, 19) is not a solution.

Answer: 80
Step-by-step explanation:
First, find the area of the square by doing 12 x 12. (Which = 144)
Then, find the area of the circle. This is found by using the formula of 1/4 • π • 9 squared.
This should get you 63.62, or 64 when rounded up.
You then subtract 64 from 144 and get 80 for your answer.

What is the slope of the line with equation y - 3= -1/2(x - 2)
Answer:
-1/2
Step-by-step explanation:
according to what I learnt, the general form of every equation is y=mx+c where y is the y value, x is the x value, m is the slope and c is the y-intercept so the equation y-3= -1/2(x - 2) in the general form wil be :
y= -x/2+4 and so m= -x/2 ,that is -1/2
Convert the following repeating decimal to a fraction in simplest form.
.6
Answer:
2/3
Step-by-step explanation:
Answer:
7/10
Step-by-step explanation:
0.6 is a repeating decimal in this case, so you can round it to .7
From there, you simply put it over ten because you cant break seven down any more than that in a simple fraction.

solve the equation 7( 4+p) = 28
P=0
P=8
P=7
Answer:
Step-by-step explanation:
1: 7(4+0)=28
7(4)=28
28=28
this is correct
Answer:
p=0
1) use distributive property
7*4+7p=28
28+7p=28... solve for p
7p=28-28
7p=0... divide both sides by 7 to find p
p=0

Mini made a recipe that yields 4 and 1 over 2 cups. If each serving is 1 over 2 cup, which expression will help Mini determine the number of servings her recipe will yield?
Answer:
1/2x = 4 1/2
Where x = Number of servings = 9 servings
Step-by-step explanation:
Mini made a recipe that yields 4 and 1 over 2 cups.
1 recipe = 4 1/2 cups
1 serving = 1/2 cups
1/2 cups = 1 servings
4 1/2 cups = x servings
Cross Multiply
1/2 × x = 4 1/2
x = 4 1/2 ÷ 1/2
x = 9/2 ÷ 1/2
x = 9/2 × 2
x = 9 servings.
Therefore, the expression tha will help Mini to determine the number of servings her recipe will yield is
1/2x = 4 1/2
Where x = Number of servings = 9 servings

Subract the sum of 3a^4b-4b^3+c^2 & 6a^4b+3b^3-6c^2 from the sum of 6a^4b-4b^3-4c^2 & 2a^4b+4b^3+7c^
Answer:
-a^4b + b^3 - 8c^2
Step-by-step explanation:
Sum of
3a^4b-4b^3+c^2 + 6a^4b+3b^3-6c^2
= 3a^4b + 6a^4b - 4b^3 + 3b^3 + c^2 - 6c^2
= 9a^4b - b^3 - 5c^2
Sum of
6a^4b-4b^3-4c^2 + 2a^4b+4b^3+7c^
= 6a^4b + 2a^4b - 4b^3 + 4b^3 - 4c^2 + 7c^2
= 8a^4b + 3c^2
Subtract
8a^4b + 3c^2 - (9a^4b - b^3 - 5c^2)
= 8a^4b + 3c^2 - 9a^4b + b^3 + 5c^2
= 8a^4b - 9a^4b + b^3 + 3c^2 + 5c^2
= -a^4b + b^3 - 8c^2

The equation of a curve is
[tex]y = 4x {}^{3} + 4px {}^{2} + 16x - 9[/tex]
Find the range of values of p such that y is an increasing function.
Let's solve for p.
[tex]y=4x3+4px2+16x−9[/tex]
Step 1: Flip the equation.
[tex]4px2+4x3+16x−9=y[/tex]
Step 2: Add -4x^3 to both sides.
[tex]4px2+4x3+16x−9+−4x3=y+−4x3[/tex]
[tex]4px2+16x−9=−4x3+y[/tex]
Step 3: Add -16x to both sides.
[tex]4px2+16x−9+−16x=−4x3+y+−16x[/tex]
[tex]4px2−9=−4x3−16x+y[/tex]
Step 4: Add 9 to both sides.
[tex]4px2−9+9=−4x3−16x+y+9[/tex]
[tex]4px2=−4x3−16x+y+9[/tex]
Step 5: Divide both sides by 4x^2.
4px² / 4x² = −4x³ − 16x + y + 9 / 4x²
Answer:
p = −4x³ − 16x + y + 9 / 4x²
The maximum number of marks attainable at a mathematics competition is 60. Kate obtains 40 marks, Priya obtains 46 marks, and Nora obtains 49 marks. The examination board decides that those who scored 80 % and above will get a gold medal, those who score 70 % to 79 % inclusive will get a silver medal and those who scored 60 % to 69 % inclusive will get a bronze medal. Determine the type of medal each of them will get
Answer: See explanation
Step-by-step explanation:
Total marks = 60
Kate = 40 marks = 40/60 × 100 = 66.7%
Kate gets a bronze medal.
Priya = 46 marks = 46/60 × 100 = 76.7%
Priya gets a silver medal
Nora = 49 marks = 49/60 × 100 = 81.7%
Nora gets a good medal.
