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

frozen [14]

Answer: 101.69

Step-by-step explanation:

Formula we use to find the z-score :-

$z=\dfrac{x-\mu}{\sigma}$ (1)

Given : $\mu=90$

$\sigma=7$

Daniel's z score : z= 1.67

Let x be the raw score for Daniel's exam grade, then substitute the values of $\mu,\ \sigma\ and \ x$ in (1), we get

$1.67=\dfrac{x-90}{7}\\\\\Rightarrow\ x-90=7\times1.67\\\\\Rightarrow\ x=11.69+90=101.69$

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

What is the y-intercept of y = -2x+6y=−2x+6?

goblinko [34]

Answer:

$6$

Step-by-step explanation:

Given: $y=-2x+6$

Since the equation is written in slope-intercept form, it is extremely easy to find the y-intercept. Slope-intercept form is written as:

$y=mx+b$

Whereas:

y: range

m: slope

x: domain

b: y-intercept

With that in mind, we can immediately tell that 6 is the y-intercept.

How to determine a quotient in simplest form

Leno4ka [110]

A. 1/2 ÷ 1/4= 1/2 x 4/1 = 4/2 = 2
b 4/5÷2/3 = 4/5 x 3/2 = 12/10= 6/5= 1 1/5
c. 7 ÷ 1/4 = 7x 4/1 = 28/1 = 28
d. 5/12÷ 5/6 = 5/12 x 6/5 = 30/60 = 1/2
e 3 1/3 ÷3/4 = 10/3 x 4/3 = 40/9= 4 4/9
f. 18/25 ÷ 3/5= 18/25 x 5/3 = 90/75 = 18/15= 1 3/15= 1 1/5
g. 1 ÷ 9/13 = 1/1 x 13/9= 13/9 = 1 4/9
h 1 3/5 ÷5/6 = 8/5 x 6/5 = 48/25 = 1 23/25
I 7/8÷7/16= 7/8x 16/7= 112/56 = 2
