What is the mean and mode of the data set shown below? {2, 4, 5, 6, 8, 2, 5, 6}

likoan [24]

The average is calculated by adding all numbers and dividing by the count:

(2+4+5+6+8+2+5+6)/8 = 38/8 = 4.75

The mode is the number that occurs most often, however, this is the case for 2, 5 and 6. A data set can have multiple modes. 2, 5 and 6 are modes.

34k+(6.3−8.1k)÷0.9=22

KATRIN_1 [288]

We have been given an equation $34k+(6.3-8.1k)\div 0.9=22$ . We are supposed to solve our given equation for k.

We can rewrite our given equation as:

$34k+\frac{6.3-8.1k}{0.9}=22$

Let us multiply both sides of equation by 0.9.

$34k\cdot 0.9+\frac{6.3-8.1k}{0.9}\cdot 0.9=22\cdot 0.9$

$30.6k+6.3-8.1k=19.8$

$22.5k+6.3=19.8$

$22.5k+6.3-6.3=19.8-6.3$

$22.5k=13.5$

$\frac{22.5k}{22.5}=\frac{13.5}{22.5}$

$k=0.6$

Therefore, the value of the k is 0.6.

So far this basketball season, Sherita made 46 of her

Tresset [83]

Answer:

<em>Sherita would need to make 10 free throws</em>

Step-by-step explanation:

<u>Proportions</u>

Sherita made 46 of her first 60 free throws in this basketball season. Calculating the average we get:

$\displaystyle \frac{46}{60}=76.7\%$

Sherita wants to have a free throw average of at least 80% in her next x free throws. This means she will have 46+x made throws out of 60+x total throws. For this new performance, the new average would be:

$\displaystyle \frac{46+x}{60+x}$
