Answer:

According to one study, brain weights of men are normally distributed with a mean of 1.50 kg and a standard deviation of 0.14 kg.

For samples of 12 men, the possible sample mean brain weights have a normal distribution with a mean of 1.50 kg and a standard deviation of 0.0404 kg.

Problem: Determine the percentage of all samples of 12 men that have mean brain weights within 0.1 kg of the population mean brain weight of 1.50 kg. Interpret your answer in terms of sampling error.

just olya [345]
40 percent off because if there is 100 percent minus 40 that's 60 percent then if our work out the other one as 100 minus 30 equals 70. 70 the sale price divided by 10 because that's how much you get off equals 7. 30 plus 7 equals 37 which means you would only get 37 percent off.

♡ The Answer ♡

-  1

*୨୧ ┈┈┈┈┈┈┈┈┈┈┈┈ ୨୧*

♡ The Explanation/Step-By-Step ♡

- 6/100 + 5/100 + 80/100 + 9/100

Apply the fraction rule! --> a/c + b/c = a + b over c

6/100 + 5/100 + 80/100 + 9/100 = 6 + 5 + 80 + 9 over 100

Add the numbers: 6 + 5 + 80 + 9 = 100!

= 100/100 Apply the fraction rule! a/a = 1

a/a = 1 = 100/100 = 1

Think about the graphs of the equations in the following system. x2+ y2 = 2 y = 2x2 – 3 Which of the following describes the sys
Feliz [49]

circle: x2+ y2 = 2  

parabola: y = 2x2 – 3

 

The standard form of equation of circle is:

( x – h )^2 + ( y – k )^2 = r^2

We are given the equation x^2 + y^2 = 2.

Where h and k are the x and y coordinates of the center. Basing on the standard equation, the center is at (0 , 0) and r = \sqrt{2}

 

The standard form of equation of parabola with the axis of symmetry parallel to the y-axis is:

(x - h)^2 = 4p (y - k)

Rearranging the given equation into this form:

x^2 = (½) y + 3/2

x^2 = ½ (y + 3)

Since 4p is positive value, therefore the parabola is opening up. The vertex is located at (0 , -3).

 

<span>Answer: circle with its center at (0, 0) and a radius of </span>\sqrt{2}; parabola opening up with its vertex at (0, –3)
