1 answer:

7 0

The difference between the standard deviation and the variance of a standard normal distribution is Option b) 1.

<h3>What is the variance of a standard normal distribution?</h3>

Variance is known to be a given average that do squared deviations from the mean, but standard deviation is seen as the square root of a given number.

Note that both above measures do show variability in a distribution, and their units often differ.

Hence, The difference between the standard deviation and the variance of a standard normal distribution is Option b) 1.

Whats the answer to this problem 9x+10=2001-X

Vilka [71]

Answer: x=1991/10

Step-by-step explanation: Step 1: Simplify both sides of the equation.

9x+10=2001−x

9x+10=2001+−x

9x+10=−x+2001

Step 2: Add x to both sides.

9x+10+x=−x+2001+x

10x+10=2001

Step 3: Subtract 10 from both sides.

10x+10−10=2001−10

10x=1991

Step 4: Divide both sides by 10.

10x

1991

An aquarium has a base in the shape of a trapezoid. The base is 100

Nat2105 [25]

Answer:

$Volume = 210L$

Step-by-step explanation:

Given

Base:

$Front = 100cm$

$Back = 50cm$

$Width = 40cm$

$Height = 70cm$

Required

Determine the volume (in litres)

First, we need to calculate the area;

Base on the parameters given, we have:

$Area = \frac{1}{2}(Front + Back) * Width$

$Area = \frac{1}{2}(100cm + 50cm) * 40cm$

$Area = \frac{1}{2}(150cm) * 40cm$

$Area = 75cm * 40cm$

$Area = 3000cm^2$

$Volume = Area * Height$

$Volume = 3000cm^2 * 70cm$

$Volume = 210000cm^3$

$1cm^3 = 0.001L$

So:

$Volume = 210000 * 0.001L$

$Volume = 210L$

A gear in a machine turns 2 1/2 times every hour.

givi [52]

We can solve this by multiplying those two numbers but we place them in improper fraction.

2 1/2 x 2 1/4
becomes
5/2 x 9/4

for fraction multiplication, just multiply numerator by numerator and denominator by denominator

5/2 x 9/4 = 45/8

we can simplify this into mixed fraction while numbers in whole numbers and remainder in numerator

5 5/8 is the answer

If g(x) = x^2 + 3x what is the value of g(-3)

Firlakuza [10]

G(-3) = (-3)²+3(-3)
Square the negative 3 and multiply the 3 and -3
g(-3) = 9-9
Subtract the numbers
g(-3) = 0

DO NOT SOLVE FOR G
G(X)= IS ANOTHER WAY OF SAYING Y=
