Answer:

mean = 70000

SD = 15239

X= 95000

Z = (X-mean)/ SD

= (95000-70000)/15239

= 1.64

Now from Z-Table

% of employees = 100(1-.9495) = 5.02%

Jordon missed 49 on his multiple choice math final and earned a grade of 65%. How many total questions were on the final exam?

harkovskaia [24]

Answer:

The exam was out of 75.

Step-by-step explanation:

You know that he earned 65% so more than half his answers were correct.

Then, you would guess and check try 49/60, 49/70, and go up by 10s or 5s. You will then realize that 49÷75 equals 65.333. This rounds up to 65.

2/5 g+3h -6 when g=10 h=6

<h3>hello!</h3>

let's evaluate this expression

$\pmb{\displaystyle\frac{2}{5}g+3h-6 }$

$\pmb{\displaystyle\frac{2}{5} *10+3(6)-6}$

$\pmb{\displaystyle\frac{2}{5} *10+18-6}$

$\pmb{\displaystyle\frac{2}{5} *10+12}$

Multiply:

$\pmb{\displaystyle\frac{2}{5} *\frac{10}{1} =\frac{20}{5} =4}$

Final Step:-

$\pmb{4+12}$

$\pmb{16}$

======================================================

<h3>note:-</h3>

Hope everything is clear; if you need any explanation/clarification, kindly let me know, and I'll comment and/or edit my answer :)
