Answer:

Step-by-step explanation:

1/9 can be simplified to 1/3 as 1/3 x 1/3 = 1/9 and 49/25 can be simplified to 7/5 as 7/5 x 7/5 = 49/25.

Now looking at both the fraction 1/3 and 7/5

1/3 simplifies to 0.34

It is an irrational value as the 3 keeps repeating.

7/5 simplifies to 1.4

It is a rational value as the decimal value is not repeating.

Thus making the second option the answer.

$\\ \sf\longmapsto \sqrt{10\times 15}$

$\\ \sf\longmapsto \sqrt{2\times 5\times 3\times 5}$

$\\ \sf\longmapsto \sqrt{5\times 5\times 6}$

$\\ \sf\longmapsto 5\sqrt{6}$

None of the above should be 4th option

Steph Curry makes 9 out of 10 free throws. If he shoots 200 free throws how many can he expect to make

MissTica

200 divided by 10 is 20 so You have to X both by 20 so 9 X 20 is 180 and 10 X 20 is 200 I think

The average marks of the first 10 students are 17 and that of the next 15 students is 18. find the mean of 25 students?

Ray Of Light [21]

Answer:

The mean of 25 students is 17.6

Step-by-step explanation:

The formula of the mean (average) is mean (average) = $\frac{S}{N}$ , where S is the sum of the data, and N is the number of the data

∵ The average marks of the first 10 students are 17

- That means the mean is 17 and the number of students is 10

∴ Average = 17

∴ N = 10

∵ Average = $\frac{S}{N}$

- Substitute average by 17 and N by 10

∴ 17 = $\frac{S}{10}$

- Multiply both sides by 10

∴ 170 = S

∴ The sum of the marks of the first 10 students is 170

∵ The average of the next 15 students is 18

∴ Average = 18

∴ N = 15

- Substitute average by 18 and N by 15

∴ 18 = $\frac{S}{15}$

- Multiply both sides by 15

∴ 270 = S

∴ The sum of the marks of the next 15 students is 270

Now to find the mean of 25 students and the two sums and divide the answer by 25

∵ S = 170 + 270

∴ S = 440

∵ N = 25

∴ Mean = $\frac{440}{25}$

∴ Mean = 17.6

The mean of 25 students is 17.6
