Answer:
Hi there! Your answer here is 11kg - the average of the seven weights is 11kg. To find the average of a group of numbers, you add all of the numbers (12, 12, 12, 12, 12, 12, 5), then divide by the count of those numbers (7).
12 + 12 + 12 + 12 + 12 + 12 + 5 (or 12*6 + 5) is equal to 77.
77 / 7 = 11.
So the average of the seven weights is 11kg.

What is a scenario from science or engineering that this graph could model?
Not all quadratics are functions. What are some examples from science and engineering where a quadratic is used but is not a function?
It should be noted that a quadratic function simply refers to a function that is in the form of f(x) = ax² + bx + c.
Examples of quadratic equationsIt should be noted that the examples of quadratic functions will be throwing a ball, hitting a golf ball, driving from a platform, etc.
In such a case, one will want to know the highest and the lowest point of the parabola that is known as the vertex. In engineering, quadratic equations are used to design curved equipments.

Which value is equivalent to: 1 1/2 divided by 4 1/2 x 1 1/3
Answer:
The answer is 4/9
Step-by-step explanation:
Hi. Here's the work.
First turn everything into an improper fraction.
[tex]1 \frac{1}{2}[/tex] ÷ [tex]4 \frac{1}{2} * 1 \frac{1}{3}[/tex] = [tex]\frac{3}{2}[/tex] ÷ [tex]\frac{9}{2} * \frac{4}{3}[/tex]
To divide fractions we multiply by the flipped version of the fraction, or the reciprocal.
[tex]\frac{3}{2}[/tex] ÷ [tex]\frac{9}{2} * \frac{4}{3}[/tex] = [tex]\frac{3}{2} *\frac{2}{9} *\frac{4}{3}[/tex]
Now we just multiply the fractions!
[tex]\frac{3 * 2 * 4}{2 * 9 * 3}[/tex] = [tex]\frac{4}{9}[/tex]
The answer is therefore 4/9. Please mark brainliest if possible and i hope you get a good grade on your homework. ;)

An inscribed angle and a central angle intercept the same arc. The inscribed angle is
the arc.
Select one:
of
O a. half
O b. equal to
O c. twice
Answer:
Half
Step-by-step explanation:
An inscribed angle is an angle with its vertex on the circle and whose sides are chords. The intercepted arc is the arc that is inside the inscribed angle and whose endpoints are on the angle.
The Inscribed Angle Theorem states that the measure of an inscribed angle is half the measure of its intercepted arc.

A police department reports that the number of reported rapes in their jurisdiction increased by 100% over the past decade. This means that the number of reported rapes today is
Answer:
the rate growed so they are more rapes now than the past decade
The number of reported rapes today is more since the percentage has increased.
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
The number of reported rapes in their jurisdiction increased by 100% over the past decade.
Number of rapes in the last decade = N
Now,
The number of rapes now.
= 200% of N
This means,
The number of rapes is more or increased.
Thus,
The number of reported rapes today is more.

For real numbers a and b, when is the equation (a +b= |a-b|
Answer:
a is positive and b is negative
Step-by-step explanation:
ok, since |a-b| is the absolute value of a-b, so whatever a-b is gonna be it must end up positive
a + b can't both be positive because then a+b not equal to a-b
a cant be negative ever because that would conflict with the absolute value part of the right side of the equation
thus a must be positive and b must be negative

Enter your answer as a decimal in the box. In. A rectangle. The width is labeled as 9 inches. A diagonal is drawn from the left bottom corner to the top right corner and labeled as 18 inches.
The length of the base of the monitor is 15.6 inches.
GivenThe size of a computer monitor is usually measured along the diagonal.
The rectangular monitor has a height of 9 in.
An 18-in.
What is the equation of diagonal?The diagonal of your equation is c, while either a or b can be your length or width.
[tex]\rm a^2 +b^2 =c^2[/tex]
Substitute all the values in the equation

George and Harriet shared some money in
the ratio 5: 3. George gave 2/3 of the money he received to Ivan.
Ivan received £30. How much money was
shared?
Answer:
Step-by-step explanation:
Ivan got 30 pounds
That was 2/3 of what he had received.
2/3 x = 30 Multiply both sides by 3/2
2/3 x * 3/2 = 30*3/2
x = 45
The parts to be divided was 5 + 3 = 8 parts. So let x be the total amount of money.
5/8 = 45 / x Cross Multiply
5x = 360 Divide by 5
x = 360 / 5
x = 72
Check
Let George's share = 5/8 * 72
Let George's share = 5*72/8 = 5*9 = 45 just as we said it should be.

An exponential function is represented by the graph is f(x) = 3(3)ˣ. Therefore. option B is the correct answer.
What is the exponential function?Exponential function, as its name suggests, involves exponents. But note that, an exponential function has a constant as its base and a variable as its exponent but not the other way round (if a function has a variable as the base and a constant as the exponent then it is a power function but not an exponential function).
From the given graph, the coordinate points are (0, 3) and (1, 6).
Use, the exponential growth formula f(x) = abˣ, where, r is rate of growth.
Rate = (6-3)/(1-0)
= 3
Now, substitute (x, y)= (0, 3) and b=3 in f(x) = abˣ, we get
3=a(3)⁰
a=3
Now, substitute a=3 and b=3 in f(x) = abˣ, we get
f(x) = 3(3)ˣ
Therefore. option B is the correct answer.

a > -5
Step-by-step explanation:
Step 1: Flip the inequality.
[tex]-21 < a - 16[/tex] [tex]a - 16 > -21[/tex]Step 2: Add 16 to both sides.
[tex]a - 16 + 16 > -21 + 16[/tex] [tex]a > -5[/tex]Therefore, a > -5.
Have a lovely rest of your day/night, and good luck with your assignments! ♡
Answer:
a > -5
Step-by-step explanation:
-21-(a-16)<0
Pull out like factors :
-5 - a = -1 • (a + 5)
Multiply both sides by (-1)
Flip the inequality sign since you are multiplying by a negative number
a+5 > 0
Subtract 5 from both sides
a > -5
