The overhead reach distances of adult females are normally distributed with a mean of 205 cm and a standard deviation of 8.3 cm.
Gre4nikov [31]

a. Find the probability that an individual distance is greater than 214.30 cm

We find for the value of z score using the formula:

z = (x – u) / s

z = (214.30 – 205) / 8.3

z = 1.12

Since we are looking for x > 214.30 cm, we use the right tailed test to find for P at z = 1.12 from the tables:

P = 0.1314

 

b. Find the probability that the mean for 20 randomly selected distances is greater than 202.80 cm

We find for the value of z score using the formula:

z = (x – u) / s

z = (202.80 – 205) / 8.3

z = -0.265

Since we are looking for x > 202.80 cm, we use the right tailed test to find for P at z = -0.265 from the tables:

P = 0.6045

 

c. Why can the normal distribution be used in part (b), even though the sample size does not exceed 30?

I believe this is because we are given the population standard deviation sigma rather than the sample standard deviation. So we can use the z test.

Factor completely 10x^3+2x^2+5x+1
liubo4ka [24]

Answer:

\boxed{\bold{\left(5x+1\right)\left(2x^2+1\right)}}

Explanation:

Factor Out \bold{2x^2} From \bold{10x^3+2x^2: \ 2x^2\left(5x+1\right)}

= \bold{\left(5x+1\right)+2x^2\left(5x+1\right)}

Factor Out Common Term 5x + 1

= \bold{\left(5x+1\right)\left(2x^2+1\right)}

\bold{\italic{Mordancy}}

Please help me Graph Y=f(x) <br><br>​
Jobisdone [24]

Step-by-step explanation:

f(0) = 0 , f(2) = -4 , f(4) = -2

0 = f(2x) → f(0) = f(2x) → x = 0 (0,0)

-4 = f(2x) → f(2) = f(2x) → x = 1 (1,-4)

-2 = f(2x) → f(4) = f(2x) → x = 2 (2,-2)

shape of the graph remain without change in vertical axis , but it is compressed in the horizontal direction.
