In a certain Algebra 2 class of 28 students, 14 of them play basketball and 19 of them

erastova [34]

Answer:

13/28

Step-by-step explanation:

Total number of students = 28

Number of students that play basketball = 14

Number of students that play baseball = 19

Number that play neither sport = 5

Number of students playing sports = 28 – 5 = 23

Number of students playing both basketball and baseball = 14 + 19 – 23 = 10

Number of students that play only basketball = 14 – 10 = 4

Number of students that play only baseball = 19 – 10 = 9

Number of students playing basketball or baseball = 4 + 9 = 13

P(a student chosen at random plays basketball or baseball) = 13/28

Korolek [52]

Answer:

Minimum = 14

$Q_1=23$

Median = 32

$Q_3=49$

Maximum = 65

Step-by-step explanation:

Step 1: Put your numbers in ascending order (from smallest to largest). For this particular data set, the order is

14, 18, 28, 29, 32, 44, 48, 50, 65

Step 2: Find the minimum and maximum for your data set. Now that your numbers are in order, this should be easy to spot.

Minimum = 14

Maximum = 65

Step 3: Find the median. The median is the middle number. The middle number in your list is 32, so

Median = 32

Step 4: Place parentheses around the numbers above and below the median.

(14, 18, 28, 29), 32, (44, 48, 50, 65)

Step 5: Find Q1 and Q3. Q1 can be thought of as a median in the lower half of the data, and Q3 can be thought of as a median for the upper half of data.

First quartile

$\bf{Q_1=\dfrac{18+28}{2}=\dfrac{46}{2}=23}$

Third quartile

$\bf{Q_3=\dfrac{48+50}{2}=\dfrac{98}{2}=49}$

Step 6: Write down your summary found in the above steps.

Minimum = 14

$Q_1=23$

Median = 32

$Q_3=49$

Maximum = 65

Water is pumped out of a 500-gallon tank at a rate of 2.5 gallons per second. The inequality 500−2.5t<100 can be used to dete

kherson [118]

Answer:

$160\ \text{s}$

Step-by-step explanation:

The inequality that represents the situation is

$500-2.5t$ where $t$ is the time in seconds

$\Rightarrow -2.5t$

$\Rightarrow 2.5t>400$

$\Rightarrow t>\dfrac{400}{2.5}$

$\Rightarrow t>160\ \text{s}$

So, the time after which there will be less than 100 gallons of water is $160\ \text{s}$ .
