35/11 = 3.18.....

This means that out of 35 rounds only 3 of them were free because every 11 rounds 1 is free.

so 35-3=32

You purchased 32 rounds.

Please mark brainliest. This was kind of a confusing question at first.

Can I please get help

Greeley [361]

Answer:

$2x^3 + 17x^2 + 25x - 50$

Step-by-step explanation:

You use the distributive property to multiply each term:

$(2x^2 + 7x - 10)(x+5) = 2x^3 + 7x^2 - 10x + 10x^2 +35x - 50$

which can then be simplified to

$2x^3 + 17x^2 + 25x - 50$

Answer:

The slope is m=2.145.

The y-intercept is b=-1.33.

Step-by-step explanation:

We have this data:

- The mean and standard deviation for x are 5.43 and 1.12, respectively.

- The mean and standard deviation for y are 10.32 and 2.69, respectively.

- The correlation is 0.893.

We have to calculate the slope and the y-intercept of the least-squares line.

With the given data, we can calculate the slope m as:

$m=r\;\dfrac{s_y}{s_x}=0.893\;\dfrac{2.69}{1.12}=2.145$

Then, the y-intercept is calculated as:

$b=\bar y-m\cdot \bar x=10.32-2.145\cdot 5.43=10.32-11.65=-1.33$
