Answer:

$sln \\ x {}^{2} - 16 {}^{2} = 256 \\ x {}^{2} = 256 - 16 {}^{2} \\ x {}^{2} = 256 - 256 \\ x {}^{2} = 0 \\ x = 0$

Answer:

${1.2}^{n} \times 2.5$

Step-by-step explanation:

it's simple my dear friend.

first, she runs 3 miles per week.

so in

${a}^{(n - 1)} \times b$

b is 3. the initial value.

increasement by 20% means she runs 1.2 times than before.

$\frac{100 + 20}{100} = \frac{120}{100} = \frac{12}{10} = 1.2$

then a=1.2

so we have now:

${1.2}^{(n - 1)} \times 3 \\ = {1.2}^{n} \times \frac{3}{1.2} \\ = {1.2}^{n} \times 2.5$

and we got it!

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
