The number of cookies found in 10 different snack bags are shown below
Answer: b. Damarias median sale is $52
Step-by-step explanation:
Hi, the correct option is b. Damarias median sale is $52.
If we rank the sales order from lowest to highest
28 46 48 48 52 52 59 60 71 192
Since 52 is the middle value, it's the median, because 4 sales are above it and 4 sales are below it.

What is the area of the base of the cone below?
Given:
Given that the height of the cone is 12 ft.
The volume of the cone is 90 ft³
We need to determine the area of the base of the cone.
Area of the base of the cone:
The area of the base of the cone can be determined using the formula,
[tex]V=\frac{1}{3} \pi r^2 h[/tex]
where the base area is [tex]A=\pi r^2[/tex]
Substituting the value of A in the above formula, we get,
[tex]V=\frac{1}{3}A h[/tex]
Substituting V = 90 and h = 12, we get;
[tex]90=\frac{1}{3}A (12)[/tex]
[tex]90=4A[/tex]
Dividing both sides by 4, we get;
[tex]22.5 =A[/tex]
Thus, the area of the base of the cone is 22.5 square feet.
Hence, Option c is the correct answer.

Final answer:
To solve for y when x equals -8 in the equation -x - 4y = 16, we substitute x with -8 and simplify the equation step-by-step to find y = -2.
Explanation:
To complete the solution of the equation and find the value of y when x equals -8, we need to substitute x with -8 in the given equation -x - 4y = 16. Let's solve the equation step-by-step:
Substitute x with -8: -(-8) - 4y = 16.Simplify the equation: 8 - 4y = 16.Subtract 8 from both sides: -4y = 16 - 8.Simplify the right side: -4y = 8.Divide both sides by -4 to solve for y: y = 8 / -4.Therefore, y = -2.The value of y when x equals -8 is -2.

shows the square-based pyramid ABCDE. The side length of the base is 96 m and the pyramid's height is 55 m. O is the centre of the square base, directly below E. M is the midpoint of AD. Use Pythagoras' theorem to find the length EM.
Answer:
EM = 73 m
Step-by-step explanation:
Using the right triangle MOE
with legs MO = 48. EO = 55 and hypotenuse EM
Applying Pythagoras' identity
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
EM² = 48² + 55² = 2304 + 3025 = 5329 ( take the square root of both sides )
EM = [tex]\sqrt{5329}[/tex] = 73

Describe and correct the error a student made in finding the average rate of change for f(x)equals0.5xsquared over the interval minus4less than or equalsxless than or equalsminus2.
Answer:
please explain it better.
Step-by-step explanation:
The student needs to use the average rate of change formula correctly. For the function f(x) = 0.5x^2 and the interval [-4, -2], the correct average rate of change is -3.
Explanation:The student is looking to find the average rate of change of the function f(x) = 0.5x^2 over the interval [-4,-2]. The average rate of change of a function over the interval [a, b] is calculated by the formula: (f(b) - f(a)) / (b - a).
For our function and interval this calculates to (f(-2) - f(-4)) / (-2 -(-4)). f(-2) is 0.5(-2)^2 = 2, and f(-4) is 0.5(-4)^2 = 8. Substituting into the formula gives (2 - 8) / (-2 -(-4)) = -6 / 2 = -3. So the correct average rate of change for f(x) = 0.5x^2 over the interval [-4,-2] is -3.

29. repetition of digits is permitted and the letters must be 2 DIFFERENT vowels (a, e, i, o, u).
a) 6,760,000
b) 3,276,000
c) 20,000
d) 6760
Answer:
c) 20,000
Step-by-step explanation:
Number of digits = 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 0 = 10,
Number of vowel letters = a, e, i, o, u = 5
Repetition of digits is permitted but repetition of vowel letters is not permitted
Let the password be presented in dash form as shown below:
____ ____ ____ ____ ____ =
D D D V V
where:
D = possible number of digits to fill the spot
V = possible number of vowels to fill the spot
Since repetition of digits is permitted, each spot marked as D can be filled with any one of 10 digits from 0 - 9
The first spot marked V has 5 possible options (a, e, i, o, u) & the second spot marked V only has 4 possible options (since repetition of vowels is not permitted).
We then place the number of possibilities in each spot and multiply them to determine the number of passwords possible
10 * 10 * 10 * 5 * 4 = 20,000
Therefore, the number of possible passwords is 20,000

You invested $10,000 into two accounts: one that has a simple 3% interest, the other with 2.5% interest. If your total interest payment after one year was $283.50, how much was in each account after the year passed?
Answer:
3300 was on 3% and 6700 on 2,5%
Step-by-step explanation:
We can say that 'a' represents the price that will go on 3% interest and 'b' 2,5% interest.
Therefore;
a + b = 10 000
And
0,03a + 0,025b = 283.5 (0,03 means 3% etc)
You can move 'b' to the other side to leave 'a' on the LHS
0,03a = 283.5 - 0,025b - - > (divide both sides by 0,03)
a=9450 - 0,8333b
Substitute this equation as 'a' in the first equation to get:
9450 - 0,8333b + b = 10 000 (move 9450 to the RHS to leave values with b on the LHS)
-0,8333b + b = 10 000 - 9450
0,1666b = 550 (divide both sides by 0,1666)
b = 3,300
Therefore 'a' will be :
a= 10 000 - 3 300
a = 6700
I hope this helps.
After solving the system of equations, the amount in the account with 3% interest was $844.50 and the amount in the account with 2.5% interest was $9155.50 after one year.
Explanation:Let's assume the amount invested at 3% interest is x and the amount invested at 2.5% interest is y. We can set up the following system of equations:
x + y = 10000 (equation 1)
0.03x + 0.025y = 283.50 (equation 2)
Multiply equation 1 by 0.03 and equation 2 by 100 to eliminate decimals:
0.03x + 0.03y = 300 (equation 3)
3x + 2.5y = 28350 (equation 4)
Now, subtract equation 3 from equation 4:
3x + 2.5y - 0.03x - 0.03y = 28350 - 300
Simplify:
2.97x + 2.47y = 28050 (equation 5)
Multiply equation 1 by 2.47 and equation 2 by -2.97 to eliminate y:
2.47x + 2.47y = 24700 (equation 6)
-2.97x - 2.97y = -842.25 (equation 7)
Add equation 6 and equation 7:
2.47x + 2.47y - 2.97x - 2.97y = 24700 - 842.25
Simplify:
-0.5x = -422.25
Divide both sides by -0.5:
x = 844.50
Substitute the value of x back into equation 1:
844.50 + y = 10000
Subtract 844.50 from both sides:
y = 9155.50
Therefore, there was $844.50 in the account with 3% interest and $9155.50 in the account with 2.5% interest after one year passed.
