Answer:

Hydrogen = 13.4

Oxygen = 85.76

Carbon =  26.8

Step-by-step explanation:

H= 13.4

When you multiply by 1/10 all you have to do is move the decimal point to the LEFT.

So... 134←. = 13.4

_______________________________________________________

O= 85.76

134×\frac{16}{25}=85.76

________________________________________________________

C= 26.8

134×\frac{1}{5}=26.8

The scores on a certain standardized test follow a normal distribution. The mean score is 76, and the standard deviation is 8.
Inessa [10]

About 4.01% of the test scores in the normal distribution that are greater than 90

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more number and variables.

Z score is given by:

z = (raw score - mean) / standard deviation

Given that mean score is 76, and the standard deviation is 8.

For x > 90:

z = (90 - 76) / 8 = 1.75

P(z > 1.75) = 1 - P(z < 1.75) = 1 -  0.9599 = 0.0401

About 4.01% of the test scores in the normal distribution that are greater than 90

What property is used in the second step of solving the inequality below?
Mkey [24]

Answer: The correct option is, (B) Addition property

Step-by-step explanation:

  • Addition property : In this property, whatever is added to one side of the equal sign must be added to the other side.

        For example : If x = y then x + z = y + z

  • Multiplication property : In this property, whatever is multiplied to one side of the equal sign must be multiplied to the other side.

        For example : If x = y then x × z = y × z

  • Transitive property : If one value (x) is equal to the another value (y), which is equal to the another value (z), then the first value (x) is equal to the third value (z).

        For example : If x = y and y = z then x = z

The given inequality expression is,

5x - 9 < 91

5x -9 + 9 < 91 + 9

(Using Addition property because we are adding 9 on both the side)

5x < 100

5x ÷ 5 < 100 ÷ 5

(Using Division property because we are dividing by 5 on both the side)

x < 20

Therefore, addition property is used in the second step of solving the inequality.
