There are two numbers, and one is 7 more than twice the other. The sum of the numbers is 3. What are the numbers? And what is the equation?
Answer:
2x + 7 = 3
2x = 3 - 7
2x = -4
2x/2 = -4/2
x= -2
Therefore the numbers are -2 and 7.

Radius is the length of the line segment from the center of the circle to an endpoint on the circle and diameter is twice the length of the radius of the circle.
Is kilobyte bigger than megabyte.
Answer:
no
Step-by-step explanation:
1 kilobyte = 1000 byte
1 megabyte = 1,000,000 byte
1 kilobyte = 1/1000 megabyte
Answer: no
Answer:
NO!!!! Kilobyte isn't BIGGER than MegabyteStep-by-step explanation:
Here's the table:
1 Kilobyte = 1,024 Bytes
1 Megabyte = 1,024 Kilobytes
1 Gigabyte = 1,024 Megabytes
1 Terabyte = 1,024 Gigabytes
From the table, we can see that Megabyte is bigger than Kilobyte

Can someone help me with this question?
A bag contains 12 movie tickets and 8 concert tickets. You randomly choose 1 ticket and do not replace it. Then you randomly choose another ticket. Find the probability that both events A and B will occur. Round your answer to the nearest tenth.
Event A: The first ticket is a concert ticket.
Event B: The second ticket is a concert ticket.
about ___%.
To solve this problem, we have to understand probability without replacement and consider the two events happening. The probability that both events occurs is 14%
Probability without replacementTo solve this problem, let's write down the data given;
Data;
Movie Ticket = 12Concert Ticket = 8But we are asked to calculate the probability that both times we pick both tickets, it would be a concert ticket.
Total number of tickets =

Let's proceed for the first event
[tex]P = \frac{8}{20}= \frac{2}{5}[/tex]
The probability the second event occurs will be

Answer:
Sides in descending order: YZ > ZX > XY
Step-by-step explanation:
Sum of all angles of triangle = 180
104 +52 + ∠Z = 180
156 + ∠Z = 180
∠Z = 180 - 156
Z = 24
The sides opposite to the biggest is the longest side.
Angles in descending order: ∠X > ∠Y > ∠Z
Sides in descending order: YZ > ZX > XYFind another angle

180-(104+52)180-15624°We know higher the angle measure higher the opposite side and vice-versa

A cone has a volume of 471cm. If the radius of the cone's base is 5cm what is the height of the
cone? (Round to the tenths place.)
(use 3.14)
Answer: the height is 18 cm.
Step-by-step explanation:
The equation for the volume of a cone is the following: V = 1/3 × B × h, where B (base) = πr². Because we are given the radius of the base, but not the base’s area itself, we will use V = 1/3πr²h.
Here, we are trying to solve for h, the height, so first we can first rearrange the equation to solve for h:
1) V = 1/3πr²h
2) h = V ÷ 1/3πr² (divide both sides by 1/3πr²h)
Now, we just need to input the given values: V = 471, π = 3.14, r = 5
h = 471 ÷ 1/3(3.14)(5²)
= 471 ÷ 1/3(3.14)(25)
= 471 ÷ 1/3(78.5)
= 471 ÷ (78.5/3)
= 18 cm

Answer:answer to 9:$1,025.00 answer to 10:$243.90 answer to 11:$1,025.15
Step-by-step explanation:
explanation to 9:First, converting R percent to r a decimal
r = R/100 = 7%/100 = 0.07 per year.
Solving our equation:
A = 500(1 + (0.07 × 15)) = 1025
A = $1,025.00
The total amount accrued, principal plus interest, from simple interest on a principal of $500.00 at a rate of 7% per year for 15 years is $1,025.00.explanation to 10:First, converting R percent to r a decimal
r = R/100 = 7%/100 = 0.07 per year.
Solving our equation:
P = 500 / ( 1 + (0.07 × 15)) = 243.90243902439
P = $243.90

Answer:
Attachment 1
Take a compass and adjust it so that it is the width of line r.
Place the point of the compass on the left point of line r and draw a circle going through the right point of line r with radius r.
Attachment 2
Take a ruler, place it so it is against line r and extend the line r across the width of the circle (this is the diameter of the circle).
Attachment 3
Place the point of the compass on the right point of line r and draw a circle (blue circle).
Place the point of the compass on the left of the diameter and draw a circle (orange circle)
Attachment 4
The points of intersection of the 3 circles are the vertices of the hexagon.

Factor using the greatest common factor.
6x^4 + 15x^2 + 24x

Answer: [tex]3x(2x^{3} + 5x + 8)[/tex]
Step-by-step explanation:
[tex]6x^{4} + 15x^{2} + 24x[/tex]
↓
[tex]3x(2x^{3} + 5x + 8)[/tex]
The factored expression is 3x(2x³ + 5x + 8).
To factor the expression 6x⁴ + 15x² + 24x using the greatest common factor (GCF), we first need to identify the common terms or factors that can be factored out from each term.
Step 1: Find the GCF of the coefficients (numbers).
The GCF of 6, 15, and 24 is 3.
Step 2: Find the GCF of the variables (x terms).
The GCF of x⁴, x², and x is x.
Step 3: Combine the GCF of the coefficients and variables.
The GCF of the entire expression is 3x.
Now, factor out 3x from each term:
3x * (2x³ + 5x + 8)
The factored expression is 3x(2x³ + 5x + 8).

The cosine function is periodic, meaning it repeats forever.
Standard form of a cosine function:

A = amplitude (height from the mid-line to the peak)2π/B = period (horizontal distance between consecutive peaks)C = phase shift (horizontal shift - positive is to the left)D = vertical shiftGiven:

A child is playing a card game where, if she does not
have a red card in her hand, she must draw cards from
the deck, and keep the cards she draws, until she
draws a red card.
is it appropriate to use the geometric distribution to
calculate probabilities in this situation?
o yes, the geometric distribution is appropriate.
o no, since each trial is not independent of the other
trials
o no, because it is not looking for the first occurrence
of success.
o no, since a success and failure on each trial cannot
be defined
The probability of choosing the red card will be 0.03%
What is probability?
In this situation, Mickey should have drawn the first 7 cards that are not diamond and then on the 8th attempt she should draw an ace.
Let A be the event of drawing 7 cards which are not diamond and B the event of drawing an ace card. therefore the required probability is
P(A∩B)=P(A)*P(B)
Now, there are 13 diamonds and 39 other cards. Hence,
P(A)=(13/39)⁷=0.1335
After drawing 7 non-diamond cards, the 8th card must be a diamond. Hence,
P(B)=0.25
Hence, P(A∩B)=P(A)*P(B)=0.1335*0.25=0.033(approximately 0.03,i.e. 3%)
Therefore the probability that Mickey will draw her first red diamond on the 8th attempt is 0.03%

Verify (x-2) is a factor
of Q(x)=x²-3x²-4x+12
Answer:
(x - 2) is not a factor of Q(x)
Step-by-step explanation:
if (x - h) is a factor pf f(x) then f(h) = 0
if (x - 2) is a factor of Q(x) then Q(2) = 0
Q(2) = 2² - 3(2)² - 4(2) + 12
= 4 - 3(4) - 8 + 12
= 4 - 12 + 4
= - 8 + 4
= - 4
since Q(2) ≠ 0 then (x - 2) is not a factor of Q(x)
However , if the polynomial was meant to be
Q(x) = x³ - 3x² - 4x + 12 , then
Q(2) = 2³ - 3(2)² - 4(2) + 12
= 8 - 12 - 8 + 12
= 0
then (x - 2) is a factor of Q(x) = x³ - 3x² - 4x + 12
