I’m confused with this question, so I can’t find the median because there is repeating numbers so yeah
Answer:
60
Step-by-step explanation:
To find the mean, add all numbers together and divide by the amount of numbers.
Total of number = 660
Number of numbers = 11
660/11 = 60
Answer:
The median is 70.
Step-by-step explanation:
I believe you may have mixed up median with mode.
Here are the definitions of both:
Mode - The value that appears the most in a data set
Median - The middle number in a list of numbers ordered from least to greatest
To find the median of this data set, we must arrange the numbers from least to greatest!
20, 20, 30, 50, 60, 70, 70, 80, 80, 90, 90
Now we just have to figure out the middle number...which is 70!
20, 20, 30, 50, 60, 70, 70, 80, 80, 90, 90
I hope this helps! Let me know if you have any other questions :D
Jill is thinking of a number. Twenty less than one forth of the number is -45. Find Jill's number.
Answer:
The number is -100, Jill can think of something else, now.
Step-by-step explanation:
x = the number
x/4 - 20 = -45 {twenty less than one-fourth of the number is -45}
x/4 = -25 {added 20 to each side}
x = -100 {multiplied each side by 4}
Answer:
-31.25
Step-by-step explanation:
Jill's number=[1/4×(-45)]-20
=-11.25-20
=-31.25

The fish population in local lake is 10,000 the population increases by half every year which function represents the fish population after X years
F(x)= 10,000 parentheses (1.5)^x
Pls help it would mean a lot I’m stressing need ASAP
Answer:
5. [tex]f(x) = 10,000 (1.5)^x[/tex]
Step-by-step explanation:
==>>We would have to multiply the original amount by 1.50^x because the initial amount would be 1, and 50% increase would be .5 so 1.5 and you raise it to the number of years to show the total increase.
Let's test itInitial: 10,000
After 1 year
10,000 + (.5*10000)
10,000 + 5000 = 15,000
--
After 2 years
15,000 + (.5*15000)
15,000 + 7500 = 22,500
--
Let's try our equation.
[tex]f(x) = 10,000 (1.5)^x[/tex]
[tex]x=2[/tex]
[tex]10,000(1.5)^2[/tex]
[tex]10,000(2.25) = 22,500[/tex]

Write the equation of a line with a point at `(-3,2)` and has a slope of `\frac{1}{2}`.
Answer:
y = (1/2)x + 7/2
Step-by-step explanation:
y = ax + b (general form of a linear function)
a = 1/2 (slope)
y = (1/2)x + b
(-3, 2) is on the line, 2 = (1/2)*(-3) + b
2 = -3/2 + b
b = 2 + 3/2
b = 7/2
equation: y = (1/2)x + 7/2

Answer:
425ft.
Step-by-step explanation:
Just add 395 and 30 together.
Hope this helps. Pls give brainliest!
Answer:
425 ft
Step-by-step explanation:
So the snorkeling was 30 ft BELOW sea level while the hike was 395 ft ABOVE sea level.
Below is negative so 30 ft below is -30
Above is positive so 395 ft above is 395
the difference between 395 and -30 looks like this:
395- (-30)
So you can simplify to get this equation:
395+30
which is 425
So the difference between the snorkel and hike is 425 ft
Hope this helps!

Sketch a possible curve of f(x) given the graphs of f ‘ (x) and f’’ (x) below:
Step-by-step explanation:
Graph 1 is a parabola and has 2 x points and a turning point
meaning it has a minimum and a maximum point.
conclave points are the highs and lows, once you show this in table then you can interpreted them on a graph see the examples attached.
Graph 1 is opposite to shown interpreted conclave so instead of --c++
we write + + c - - and draw on quadrant 1 instead of quadrant 3
graph 2 is decreasing so instead of -+ c then + + it would show + - c then - - so the curve stays in quadrant 3 and 4. Also where c is we draw a 0 and say whether it is minimum or maximum point.
Both graph 1 and 2 demonstrate minimum points for their f(x) for c.
so in your workings within the table you write min as seen in red within the attachment. They wrote max, but you write min as you are in decreasing conclave fx values that reach min point c then they increase and become parabolas.
What equation, in point-slope form, matches the graphed line shown?
Question 3 options:
y−5=−23(x+9)
y−6=45(x−2)
y−2=−34(x−6)
y+6=45(x+3)
Answer:
Here’s the graph
Step-by-step explanation:
The equation of the line in point-slope form that matches the graph passing through the points (6, 2) and (10, -1) is:
y = (-3/4)x + 13/2
The correct answer is: Option C: y - 2 = -3/4(x - 6).
Here, we have to find the equation of the line in point-slope form that matches the graph passing through the points (6, 2) and (10, -1), we first need to find the slope (m) of the line using the formula:
[tex]m = (y_2 - y_1) / (x_2 - x_1)[/tex]
where [tex](x_1, y_1) = (6, 2) ; (x_2, y_2) = (10, -1)[/tex].
m = (-1 - 2) / (10 - 6)
m = (-3) / 4
Now that we have the slope (m), we can use the point-slope form of the equation of a line:
[tex]y - y_1 = m(x - x_1)[/tex]
Using the point (6, 2):
y - 2 = (-3/4)(x - 6)
Now, simplify the equation:
y - 2 = (-3/4)x + 9/2
Finally, move -2 to the other side to get the equation in the point-slope form (y = mx + b):
y = (-3/4)x + 9/2 + 2
y = (-3/4)x + 9/2 + 4/2
y = (-3/4)x + 13/2
So, the equation of the line in point-slope form that matches the graph passing through the points (6, 2) and (10, -1) is:
y = (-3/4)x + 13/2
The correct answer is: Option C: y - 2 = -3/4(x - 6).

when a number divides another number exactly the smaller number is called
Answer:
1) A number that divides another number evenly is called a factor of that number. For example, 16 can be divided evenly by 1, 2, 4, 8, and 16. So the numbers 1, 2, 4, 8, and 16 are called factors of 16.
2) A number that divides a given set of numbers is called a common factor of the numbers.

Answer:
4x - 5 = 2(2x + 1)
Step-by-step explanation:
4x - 5 = 2(2x + 1)
4x - 5 = 4x + 2
Then you would subtract the 4x on each side leaving you with:
-5 = 2
And obviously the value of -5 does not equal the value of 2 so therefore this equation has no solution

Step-by-step explanation:
Divide the Y values by the X values to check your answer
Answer:
C
Step-by-step explanation:
The question asks for a 0.3 constant of proportionality between 'x' and 'y'.
So, if you multiplied 0.3 to the number in 'x', you would get the number in 'y'.
By process of elimination, we can find that in A, 0.3 * 6 is not 2 and it's the same for all the other numbers in the table.
For B, 3*0.3 is not 1.8 and 0.3 multiplied by the other numbers in B do not match the number in y.
The only answer that matches is C, 4*0.3 is 1.2, 8*0.3 is 2.4, and 13*0.3 is 3.9.
So, the answer is C.
