Answer:

5 / 3

Step-by-step explanation:

Slope of the line = (y2 - y1) / ( x2 - x1)

= (5 - 0) / ( 3 - 0 )

= 5 / 3

Solve this quadratic equation by completing the square.<br><br> x^2+10x=7

bogdanovich [222]

Ok, so the quadratic coefient is 1, so great

take 1/2 of the linear coefient and square it
10/2=5, (5)^2=25
add that to both sides
x^2+10x+25=7+25
factor perfect square trionomial
(x+5)^2=32
squaer root both sides
x+5=+/-4√2
minus 5
x=-5+/-4√2

x=-5+4√2 and -5-4√2

san4es73 [151]

Answer:

3:2

Step-by-step explanation:

The ratio of boys to girls will be 12:8

But, this can be simplified, since both numbers are divisible by 4.

12/4 = 3

8/4 = 2

So, the simplified ratio of boys to girls is 3:2

Exercises 1–5

Degger [83]

Answer: The estimated value for population mean rating based on these ten sampled ratings is 7.3 .

Step-by-step explanation:

Given : A random sample of size ten produced the following ratings in the computer games rating example in the last lesson:

12, 5, 2, 4, 1, 4, 18, 10, 1, 16.

Let x denotes any value in the above data.

${\sum_{i=1}^{10}x_i}{10}=73$

We know that the sample mean $(\overline{x})$ is the best estimate to the population mean $(\mu)$ .

Sample mean= $\overline{x}=\dfrac{\sum_{i=1}^{n}x_i}{n}$

Here , n= 10

$\overline{x}=\dfrac{\sum_{i=1}^{10}x_i}{10}$

$\overline{x}=\dfrac{73}{10}=7.3$

Therefore , the estimated value for population mean rating based on these ten sampled ratings= 7.3
