Daniel wanted to know his approximate score on the final exam for his mathematics class. His professor hinted that his score was

hammer [34]

Answer: The raw score for Daniel's exam grade is 101.69.

Step-by-step explanation:

For x be any random variable.

Formula for z-score :

$z=\dfrac{x-\mu}{\sigma}$ , where $\mu$ = population mean

$\sigma$ = population standard deviation.

Let x be the raw score for Daniel's exam grade.

As per given , we have

$\mu=90$ , $\sigma=7$ and z= 1.67 , put these values in the above formula , we get

$1.67=\dfrac{x-90}{7}\\\\\Rightarrow\ x-90=7(1.67)=11.69\\\\\Righarrow\ x=11.69+90=101.69$

Hence, the raw score for Daniel's exam grade is 101.69.

Write an algebraic expression for the given quantity. Let x represent the unknown value. One-eight of the suu of a number and th

yan [13]

<u>ANSWER: </u>

The algebraic expression for one-eight of the sum of a number and three is $\frac{x}{8}+\frac{3}{8}$

<u>SOLUTION: </u>

Given, "x" represent the unknown value.

We have to write the algebraic expression for:Here, the number is unknown term, so x represents the number.

Now according to given information ,

One - eight of the sum of a number and three.

→ $\frac{1}{8}$ of the sum of x and 3

→ $\frac{1}{8} \times (x + 3)$

→ $\frac{x+3}{8}$

→ $\frac{x}{8}+\frac{3}{8}$

Hence the algebraic expression for one-eight of the sum of a number and three is $\frac{x}{8}+\frac{3}{8}$

cluponka [151]

Answer:

a). 5x - 12 b). 2x(4x + 3)

Step-by-step explanation:

a). 7(x - 2) - 2(x - 1)

= 7x - 14 - 2x + 2

= 5x - 12

b). 8x² + 6x

2x(4x + 3)
