Answer:
2. 4 outcomes 3.12
Step-by-step explanation:
John is at Staples buying a few items for math class. He buys a notebook for $1.49, a calculator for $12.49, and a pack of highlighters for $3.50. The sales tax is 7%. How much does John spend at the store including tax? Round to the nearest cent.
Answer: (1.49+12.49+3.50)+1.22 = $18.70
Step-by-step explanation:
Add all the prices of stuff together
(1.49+12.49+3.50) = 17.48
Multiply by 0.07 to get the tax
(1.49+12.49+3.50)*0.07=1.22
Add the tax onto the previous answer
(1.49+12.49+3.50)+1.22

Answer: g(x) = f(x-2)
Step-by-step explanation:
When plugged into desmos, g(x) = 1/4(2^x) - 4
g(x) = f(x-2) is the only equation that lines up with this equation I stated above.
Note: if you try to do this yourself on desmos graphing calculator, make sure to add f(x) first (f(x) is: f(x) = 2^x - 4).

Answer:
114,2
Step-by-step explanation:
the square = 8×8 = 64
the quarter circle=
[tex] \frac{1}{4} \times ( {8}^{2} \times 3.14) = 16 \times 3.14 = 50.24[/tex]
64+50,24=114,24
I really need this plz
Answer:
2. Negative because if we multiply [tex] - \frac{3}{4} [/tex] by itself 13 times the answer resulting will be negative as if a negative number is multiplied to an other negative number odd number of times it will result in a negative number.
Samuel used clay to make a diorama of the pyramids in Ancient Egypt. He made two triangular pyramids and three rectangular pyramids. How much clay did he use to create all the pyramids
Answer:
124.16 cubic meter of clay will be used to create all the pyramids
Solution
The total clay used is equal to the sum of volumes of two triangular and three rectangular pyramids.
For Rectangular Pyramid,
Volume of three rectangular pyramids
3 * BH/3 = BH
Substituting the given values in above equation, we get -
15.5 * 5 = 77.5 cubic centimeter
For triangular Pyramid,
Volume of two triangular pyramids
2 * BH/3
2* 10 * 7/ 3
46.67 cubic centimeter
Total clay used = Volume of 3 rectangular pyramid + volume of 2 triangular pyramid = 77.7 + 46.67 = 124.16 Cubic centimeter

========================================================
Explanation:
1 liter = 1000 mL
Note how 1000/200 = 5, which means that if one carton is 200 mL, then five cartons gets us 5*200 = 1000 mL = 1 liter. If it takes five cartons to get 1 liter, then we'll need five times as many cartons to get to 5 liters. So 5*5 = 25 cartons is our goal.
---------
We could also solve like this
(1 carton)/(200 mL) = (x cartons)/(5000 mL)
1/200 = x/5000
1*5000 = 200x .... cross multiply
5000 = 200x
200x = 5000
x = 5000/200 ..... divide both sides by 200
x = 25

Answer:
I am 100% confident in my calculations. I'm not 100% sure about interpreting. Sorry I can't be of more help.
Part A:
Median: 4.5
IQR: 3.5
Mode: 6
I think the median/IQR is a better measure of center and variability because the range of data is so big (10 - 0 = 10), and the data skews to the right with the 6s.
Part B:
I would say no. It is the one that occurs most frequently, but there are many more times she rides less than 6, which is why the median is 4.5
Step-by-step explanation:
Mean: 4.714
MAD: 2.43
Median: 4.5
IQR: 3.5
Mode: 6
the number set in order:
0, 2, 2, 2.5, 2.5, 3, 4, 5, 6, 6, 6, 8, 9, 10
The median (middle number) is two numbers: 4 and 5, so the median is 4.5
The first quartile/Q1 (middle of the bottom half of data) is 2.5, the third quartile/Q3 (middle of the top half of data) is 6. So the IQR (interquartile range) is 6 - 2.5 = 3.5
The mean is the sum of the numbers divided by the quantity of the numbers, so 66/14 = 4.714
the mean absolute deviation is found by calculating the mean, and then finding the absolute value of the difference between each number of the set and the mean...then adding those together and finding the mean of that set. Labor intensive, but that's 34/14 = 2.42857143
