Answer:

Step-by-step explanation:

x₁ = 0 ; y₁=0 &

x₂ = 1 ; y₂=2

Slope = $\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}$

$=\dfrac{2-0}{1-0}\\\\\\=\dfrac{2}{1}\\\\\\= 2$

Slope = 2

Your friend, Susannah, manages a sandwich shop. She collects data on the number of turkey sandwiches sold per day for a week. Ex

ExtremeBDS [4]

Susannah's data are illustration of measure of central tendencies

(a) The mean

To calculate the mean, she needs to divide the total number of turkey sandwiches sold, by the number of days.

The total is:

$\mathbf{Total = 73 +88+85+88+99+134+129}$

$\mathbf{Total = 696}$

The number of days is:

$\mathbf{Day = 7}$

So, the mean is:

$\mathbf{Mean =\frac{Total}{Days}}$

$\mathbf{Mean =\frac{696}{7}}$

$\mathbf{Mean =99.4}$

Hence, the mean number of turkey sandwiches sold is 99.4

(b) The median

To calculate the median, she needs to arrange the data in ascending or descending order, then select the middle item.

In ascending order, we have: 73, 85, 88, 88, 99, 129, 134

The middle item is 88

So:

$\mathbf{Median = 88}$

Hence, the median number of turkey sandwiches sold is 88

(c) The mode

This is the data that occurs most.

From the dataset, 88 appears twice (more than others).

So:

$\mathbf{Mode = 88}$

Hence, the mode number of turkey sandwiches sold is 88

(d) The range

This is the difference between the highest and least data

From the dataset,

The highest is 134, and the least is 73

So:

$\mathbf{Range =134 - 73}$

$\mathbf{Range =61}$

Hence, the range of turkey sandwiches sold is 61

The measure that would be most helpful is the median, because it is not affected by outliers.

19 ,20 ,21 please show your work (worth 100 points)

RoseWind [281]

Answer:

Step-by-step explanation:

19 - you would divide number of beads by beads per bracelet to get number of bracelets

blue = 258/6 = 43

silver = 428/9 = 47.56, round down because we're looking at complete bracelets = 47

rose = 102/3 = 34

white = 258/7 =36.86, round down again = 36

20 - they can make 43 + 47 + 34 + 36 = 160 bracelets before they run out, and they will run out of rose first since it has the smallest number of bracelets

21 - multiply num of beads by num of bracelets for each color and add them up

blue = 6 * 7 = 42

silver = 9 * 7 = 63

rose = 3 * 7 = 21

white = 7 * 7 = 49

42 + 63 + 21 + 49 = 175

X=a-2by^2 Make “y” as a subject

Alex Ar [27]

Answer:

Let’s assume a,b,x real. Then all we require of y is y2 is real, so y

can be real or purely imaginary, but not an arbitrary complex number.

The hard question in these is always, do we need ±

? Here the answer is yes. It’s basically asking is there one solution or two, and in this problem we have two.

Solve for y

: x=a−2by2
