a.
mean: 43.5, mode: 46
b.
mean: 42, mode: 46
c.
mean: 43.5, mode: 42
d.
mean: 46, mode: 42

b.  mean: 42, mode: 46

Step-by-step explanation: if x1,x2,x3,...,xn are n observations then

mean=( x1+x2+...+xn)/n and mode is the element having the highest frequency i.e. element occuring most of the time

mean=(59+16+57+46+58+21+36+41+23+64+20+66+40+51+28+46)/16

        =42

46 occurs twice while all other numbers occur only once so, mode=46

The answer on e2020 is B! 42, 46 (:

Step-by-step explanation:

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
