Answer:

Step-by-step explanation:

a) Five tests: 85,85,60,62 and 59

Mean = average

= (85+85+60+62+59)/5

= 351/5

Mean = 70.2

Median = middle number (order from least to greatest)

59 , 60, 62, 85, 85

Median = 62

Mode = the ones repeated more often = 85

b) Since mode is the highest score, compare to mean and median.

So mode is the best supports Rolinda's claim that she is doing well in her Spanish class

c) Rolinda's claim is misleading because her first two tests were 85 but then it started decreasing each test after.

The formula for the area of a trapezold with altitude k and bases m and n is A=k/2(m+n)

Ghella [55]

Answer:

$m=\frac{2A-kn}{k}$

Hence, option C is true.

Step-by-step explanation:

Given the expression

$A=\frac{k}{2}\left(m+n\right)$

Solving for 'm'

$A=\frac{k}{2}\left(m+n\right)$

Flip the equation

$\frac{k}{2}\left(m+n\right)=A$

Expanding by applying the distributive law: $a\left(b+c\right)=ab+ac$

$\frac{1}{2}km+\frac{1}{2}kn=A$

Add (-1)/2 × kn to both sides

$\frac{1}{2}km+\frac{1}{2}kn+\left(-\frac{1}{2}kn\right)=\left(-\frac{1}{2}kn\right)+A$

simplify

$\frac{1}{2}km=-\frac{1}{2}kn+A$

Divide both sides by k/2

$\frac{\frac{1}{2}km}{\frac{k}{2}}=\frac{-\frac{1}{2}kn+A}{\frac{k}{2}}$

$m=\frac{2A-kn}{k}$

Therefore,

$m=\frac{2A-kn}{k}$

Hence, option C is true.
