Find the z-score corresponding to the given area. Remember, z is distributed as the standard normal distribution with mean of an
grigory [225]

Answer:

Step-by-step explanation:

The z-score corresponding to a given area of a distribution, is the number of standard deviations that the values in that area have/are from the mean.

In this case, we have a STANDARD normal distribution. In a standard normal distribution, the mean is 0 and the standard deviation is 1.

The Z-score corresponding to a given area, say the 30th percentile is

X = 0 + (-0.524)(1)

Hence, the X (number of values in the given percentile - in this case, 30th) is same as the z-table or z-calculator value for the 30th percentile in ANY normal distribution.

5/8 divided by 3/4 what the answer
charle [14.2K]

Answer:

20/24. Simplified answer is 5/6

Step-by-step explanation:

5/8 divided by 3/4 is the same as asking 5/8 times 4/3

When dividing a number by a fraction, you can always just multiply by the fraction with its numerator and denominator switched!

So, now we have 5/8 times 4/3

Step 1: Multiply the numerators together. 5 times 4 = 20

Step 2: Multiply the denominators together. 8 times 3 = 24

Step 3: Put the new numerator over the new denominator. 20 over 24 is 20/24

Step 4: Simplify the fraction if necessary. 20 and 24 share a common factor of 4, so divide both the numerator and denominator by 4.  

20 divided by 4 = 5

24 divided by 4 = 6

So, 20/24 is equal to 5/6.

1.what is the volume of the small cone in terms of pi
svp [43]

Step-by-step explanation:

<u>Step 1:  Find the radius of the big cone</u>

\frac{radius_1}{height_1} = \frac{radius_2}{height_2}

\frac{2}{5}=\frac{x}{10}

2(10)=5(x)

20/ 5=5x / 5

4=x

<u>Step 2:  Find the volume of the small cone</u>

V = \frac{\pi*r^2*h} {3}

V = \frac{\pi * 2^2 * 5}{3}

V = \frac{20\pi}{3}\  units^3 ← Volume of Small Cone

<u>Step 3:  Find the volume of the large cone</u>

<u />V = \frac{\pi*r^2*h} {3}

V=\frac{\pi*4^2*10}{3}

V = \frac{160\pi}{3}\  units^3 ← Volume of Large Cone
