Step-by-step explanation:

mean = sum of all data points / number of data points

(22+16+18+14+16+34+20)/7 = 140/7 = 20

median is the number, where half of the data points are smaller, and the other half are larger.

first we need to sort the data points

14, 16, 16, 18, 20, 22, 34

median = 18

mode is the data point occurring most often.

mode = 16 (occurring 2 times, while the others occur only once).

range is the difference between the largest and the smallest data point.

range = 34 - 14 = 20

A 3 metre long piece of ribbon is cut into

Gnoma [55]

Step-by-step explanation:

3 meters = 300 cm

anyway, the ratio tells us that the whole ribbon can be seen as the combination of 3 + 2 = 5 equally long parts.

one such part is then

3 m / 5 = 0.6 m or 60 cm

the shorter piece is 2 of these parts long :

2 × 0.6 = 1.2 m or 120 cm

Find the equation of the exponential function, in y=a(b)^x form that passes through the points (-2,3) and (6,35). Round both a a

Lesechka [4]

I supose your function is: $y(x)=a \cdot b^x$

Step 1. Replace the coordinates of the first point in your equation:
x=-2, y=3

$3=a \cdot b^{-2}$

Solve the equation for "a":
$a=3 \cdot b^2$

Step 2. Replace the coordinates of the second point in your equation:
x=6, y=35

$35 = a \cdot b^6$

Replace the value of "a" from Step 1.
$35 = 3 \cdot b^2 \cdot b^6$
Calculate "b":
$b= \sqrt[8]{\frac{35}{3}} = 1.359466$

Step 3. Replace "b" in first equation and calculate "a":
$a=3 \cdot b^2=5.5444434$

The equation is:
$y(x)=5.54 \cdot 1.36^x$
