Answers
Answer:B and C
Step-by-step explanation:
The correct stemplot is:
1: 1 2 3 4 5 6 7 9
2: 5 5 6 7 8 9
3: 1 2 3 5 8 9
What is the stemplot?A stem-and-leaf display or stem-and-leaf plot is a device for presenting quantitative data in a graphical format, similar to a histogram, to assist in visualizing the shape of a distribution.
So for given number of minutes to complete quiz we sort them out as :
11, 12, 13, 14, 15, 16, 17, 19, 25, 25, 26, 27, 28, 29, 31, 32, 33, 35, 38, 39

In the data above, 13
1 is the stem
3 is the leaf
to make a stemplot.
1: 1 2 3 4 5 6 7 9
2: 5 5 6 7 8 9
3: 1 2 3 5 8 9
which is the correct stemplot for the given minutes where colon sign is used to indicate the column.
Thus the correct stemplot is:
1: 1 2 3 4 5 6 7 9
2: 5 5 6 7 8 9
3: 1 2 3 5 8 9

What is the value of x?
Answers
Answer:
I have no idea. But I just want to let you know to not put this many points, because people are going to take them without answering the question. And I don't know the answer because there are multiple x's.
Answer:
x = 8
Step-by-step explanation:
Remark
I agree with the other responder. You need only pay 20 points to get our attention. (20 will give us 10).
The length from the intersect point to the circle times the entire length of the secant is equal to any other secant divided up the same way.
Put simpler
Equation
(x + 2)(x + 2 + 2x- 8) = (x + 1)(x + 1 + 2x - 5)
Combine like terms
Solution
(x + 2)(3x - 6) = (x + 1)(3x - 4) Remove the brackets on both sides.
3x^2 + 6x - 6x - 12 = 3x^2 + 3x - 4x - 4 Combine the like terms
3x^2 - 12 = 3x^2 - x - 4 Subtract 3x^2 from both sides
- 12 = - x - 4 Add 4 to both sides
-12 +4 = - x
- 8 = - x Multiply both sides by -1
x = 8

The initial value of the exponential function is 2.
What are Exponential Functions?Exponential functions are functions where the independent variable, x is in the exponent.
Given is the graph of the exponential function.
The initial value of the exponential function is the value of the function when the value of the independent variable is 0.
The general form of exponential function is y = abˣ
When x = 0, y = a, which is the initial value.
Here, when x = 0, the graph touches the Y axis.
y = 2
Hence the initial value is 2.

3 boys shared a box of chocolate. The first boy got 3/8 of the total and the 2nd boy got 2/5 of the remainder and the 3rd boy got 9. How many chocolates were in the box and how many did the boy with the smallest share get?
Answers
Answer:
1. there were 24 chocolates in the box at first.
2. the boy with the smallest share received 6 chocolates.
Explanation:
let's represent the number of chocolates in the box with 8x.
the first boy got ⅜ × 8x = 3x chocolates. now, there are 8x - 3x = 5x chocolates remaining.
the second boy got ⅖ × 5x = 2x chocolates. now, there are 5x - 2x = 3x chocolates remaining.
3x = 9 chocolates
x = 3 chocolates
since the original number of chocolates was represented by 8x, we now know that there were 8 × 3 = 24 chocolates in the box at first.
the first boy got 9 chocolates, the second boy got 6 chocolates and the last boy got 9 chocolates. thus, the boy with the smallest share got 6 chocolates.

The area of a triangle is 36 sq cm. The triangle's height is 8 cm. What is the length of the base of the triangle?
Answers
Answer:
9 cm
Step-by-step explanation:
Given :
Area, A = 36cm²
Height, h = 8cm
Using the relation :
Area, A of triangle :
A = 1/2 * base * height
36 = 0.5 * base * 8
36 = 4 * base
base = 36 / 4
Base = 9 cm
Length of base is 9cm
Nathaniel goes to a store an buys an item that costs xx dollars. He has a coupon for 40% off, and then a 7% tax is added to the discounted price. Write an expression in terms of xx that represents the total amount that Nathaniel paid at the register.
Answers
Answer: He pays x*0.642
Step-by-step explanation:
Suppose that we have an object with an initial price P.
If we have a discount of X%, then the new price will be:
NP = P*(1 - X%/100%)
And if we have an increase of X%, the new price is:
NP = P*(1 + X%/100%)
In this case, we have an initial item that costs x dollars, first we have a coupon for 40% off, then we have a discount of 40%.
Then the new price is:
NP = x*(1 - 40%/100%) = x*(1 - 0.4) = x*0.6
Now we add a tax of the 7%, then the final price will be:
FP = (x*0.6)*(1 + 7%/100%) = (x*0.6)*(1 + 0.07) = x*(0.6*1.07) = x*0.642
This is the total amount he pays at the register.

A die is rolled 3. What is the probability of getting a 1 on the first roll, a 2 on the second roll, and a 3 on the third roll
Answers
Answer:
The probability of getting 1,2 and 3 after rolling once , second and thrice is
1/6
Step-by-step explanation:
These are all independent events.
The sample space = [1,2,3,4,5,6]
A die has 6 sides
1. If this die is thrown once, the probability of getting a 1 is = 1/6
2. If we roll the dice a second time, the probability of getting a 2 is independent from the first time it was rolled, so the sample space remains the same. The probability is also 1/6
3. If we rolled a 3rd time the probability remains 1/6 also
