What is the mean of the values in the stem-and-leaf plot?
Enter your answer in the box.
Answers
Answer:
mean = 24
Step-by-step explanation:
the mean is calculated as
mean = \(\frac{sum}{count}\)
the sum of the data set is
sum = 12 + 13 + 15 + 28 + 28 + 30 + 42 = 168
there is a count of 7 in the data set , then
mean = \(\frac{168}{7}\) = 24
Let u=(5,-12)and c= -3. What is llcull
Answers
If c is a scalar and u is a vector, then ||cu|| = |c| ||u||.
(|…| means absolute value, ||…|| means magnitude)
We have
||u|| = √(5² + (-12)²) = √169 = 13
and with c = -3, it follows that
||cu|| = |-3| × 13 = 3 × 13 = 39

Answers
Ken will receive a total dividend payment of $75 for that quarter.
We have to given that,
Ken owns 500 shares of LaceNBrace, which makes hockey equipment.
And, He receives a notice stating the company will be paying $0.15 dividend per share.
Now, For the total dividend payment Ken receives for that quarter, we can multiply the dividend per share by the total number of shares he owns:
= $0.15 per share x 500 shares
= $75
Therefore, Ken will receive a total dividend payment of $75 for that quarter.

By using the coordinates of the labeled point, the point-slope equation of the line include the following: D. y + 5 = -3(x - 3)
How to determine an equation of this line?In Mathematics and Geometry, the point-slope form of a straight line can be calculated by using the following mathematical equation (formula):
y - y₁ = m(x - x₁)
Where:
x and y represent the data points.m represent the slope.0 5 2 -2
First of all, we would determine the slope of this line;
Slope (m) = (y₂ - y₁)/(x₂ - x₁)
Slope (m) = (4 + 5)/(0 - 3)
Slope (m) = -9/3
Slope (m) = -3
At data point (3, -5) and a slope of -3, a linear equation for this line can be calculated by using the point-slope form as follows:
y - y₁ = m(x - x₁)
y - (-5) = 3(x - 3)
y + 5 = -3(x - 3)

What sum would yield a simple interest of 70$ in 4 years if the rate interest is 3.5% p.a
Answers
Answer:
$500
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 3.5%/100 = 0.035 per year,
then, solving our equation
P = 70 / ( 0.035 × 4 ) = 500
P = $ 500.00
The principal required to
accumulate interest of $ 70.00
on a rate of 3.5% per year for 4 years is $ 500.00.

Now divide 20cm by 300cm:
20cm/300cm=1/15
Multiply (1/15) by 100% to convert the fraction to a decimal:

Polygon ABCD with A (0,4), B (-4, 8), C (3, 3), and D (4, -2), is dilated by a scale factor of /2. What are the new coordinates? Is this a reduction or enlargement? *
Answers
The formula for dilations with center at origin is
\(\begin{gathered} D_{O,k}(x,y)=(kx,ky) \\ \text{ Where O is the center of dilation at (0,0) and} \\ k\text{ is the scale factor} \end{gathered}\)Likewise when
*k > 1, the dilation is an enlargement
*k < 1, the dilation is a reduction
*k = 1, the dilation is a congruence
So, in this case, you have
\(k=\frac{1}{2}<1\)Then, the dilation of the polygon is a reduction.
Now, finding the new coordinates of the polygon, you have
\(\begin{gathered} A(0,4)\rightarrow A^{\prime}(\frac{1}{2}\cdot0,\frac{1}{2}\cdot4)=A^{\prime}(0,2) \\ \end{gathered}\)\(B(-4,8)\rightarrow B^{\prime}(\frac{1}{2}\cdot-4,\frac{1}{2}\cdot8)=B^{\prime}(-2,4)\)\(C(3,3)\rightarrow C^{\prime}(\frac{1}{2}\cdot3,\frac{1}{2}\cdot3)=C^{\prime}(1.5,1.5)\)\(D(4,-2)\rightarrow D^{\prime}(\frac{1}{2}\cdot4,\frac{1}{2}\cdot-2)=D^{\prime}(2,-1)\)Therefore, the correct answer is C. A'(0,2), B'(-2,4), C'(1.5,1.5), D'(2,-1): Reduction.

Answer:
∠C = ∠A = 53°
∠D = 127°
Step-by-step explanation:
Opposite angles of a parallelogram are congruent, so ...
∠A = ∠C
13x -25 = 9x -1
4x = 24
x = 6
∠C = ∠A = 9(6) -1
∠C = ∠A = 53°
Adjacent angles of a parallelogram are supplementary.
∠D = 180 -∠C
∠D = 180 -(9(6) -1) = 180 -53
∠D = 127°

The temperature in a hotel is 21 °C.
The temperature in the hotel is 26,7°C warmer than at the top of the mountain.
The temperature at the top of the mountain is 3.2°C colder than at the bottom of the mountain.
Work out the temperature at the bottom of the mountain.
Answers
The temperature at the bottom of the mountain is 50.9 °C.
Let's work through the given information step by step to find the temperature at the bottom of the mountain.
The temperature in the hotel is 21 °C.
The temperature in the hotel is 26.7 °C warmer than at the top of the mountain.
Let's denote the temperature at the top of the mountain as T_top.
So, the temperature in the hotel can be expressed as T_top + 26.7 °C.
The temperature at the top of the mountain is 3.2 °C colder than at the bottom of the mountain.
Let's denote the temperature at the bottom of the mountain as T_bottom.
So, the temperature at the top of the mountain can be expressed as T_bottom - 3.2 °C.
Now, let's combine the information we have:
T_top + 26.7 °C = T_bottom - 3.2 °C
To find the temperature at the bottom of the mountain (T_bottom), we need to isolate it on one side of the equation. Let's do the calculations:
T_bottom = T_top + 26.7 °C + 3.2 °C
T_bottom = T_top + 29.9 °C
Since we know that the temperature in the hotel is 21 °C, we can substitute T_top with 21 °C:
T_bottom = 21 °C + 29.9 °C
T_bottom = 50.9 °C
Therefore, the temperature at the bottom of the mountain is 50.9 °C.

Isabel works as a tutor for $7 an hour and as a waitress for $15 an hour. This month, she worked a combined total of 104 hours at her two jobs.
Lett be the number of hours Isabel worked as a tutor this month. Write an expression for the combined total dollar amount she earned this month.
Answers
Answer:
7x + 15y
Step-by-step explanation:
Not sure what letter it wants me to use as variables, so I'll use my own.
I'm gonna let x = number of hours worked as a tutor
y = number of hours worked as a waitress
Since those hours all add up to 104, we add x and y to equal 104
x + y = 104
Since she earns $7 an hour as a tutor, multiply x by 7 like this: 7x
Since she earns $15 an hour as a waitress, multiply y by 15 like this: 15y
They both have to be added to find the total dollar amount she earned this month
7x + 15y = ?

Assume that the probability of a driver getting into an accident is 7.1%, the average cost of an accident is $14,886.0 , and the overhead cost for an insurance company per insured driver is $110 . What should the driver's insurance premium be?
Answers
Answer: $1166.91
Step-by-step explanation:
The following can be deduced from the question:
Average cost of an accident = $14,886.05
Probability of a driver getting into an accident = 7.1% = 7.1/100 = 0.071.
Overhead cost for insurance = $110
Therefore, the expected cost of an accident will be calculated as:
= Average cost of an accident × Probability of a driver getting into an accident
= $14,886.05 × 0.071
= $1056.91
Therefore, the driver's insurance premium will then be:
= $1056.91 + $110
= $1166.91

th term rule of the linear sequence 13 7 1 -5 -11
Answers
Answer:
-53, f(n) = -6(n-1) + 13
Step-by-step explanation:
given the equation to this linear/arithmetic sequence for the nth term: f(n) = -6(n-1) + 13
f(12) = -6(12-1) + 13
f(12) = -6(11) + 13
f(12) = -66 + 13
f(12) = -53
*substitute and simplify*
______________
f(n) = f(1) + d(n-1)
given f(1) = 13, f(2) = 7, and f(3) = 1
7-13 = 1-7 = -6 = d
= f(1) + d(n-1)
f(1) = 13 so
the equation must be f(n) = 13 - 6(n-1) or -6(n-1) + 13

Paula and Pedro were selling water bottles to raise money for their school. The ratio of water bottles Paula sold to water bottles Pedro sold is 3:5. If together Paula & Pedro sold a total of 72 water bottles, how many did each sell?
Answers
Step-by-step explanation:
x = number of bottles Paula sold
y = number of bottles Pedro sold
x + y = 72
x = 72 - y
x/y = 3/5
(72 - y)/y = 3/5
5(72 - y) = 3y
360 - 5y = 3y
360 = 8y
y = 45
x + y = 72
x + 45 = 72
x = 27
so,
Paula sold 27 water bottles, and Pedro sold 45.
