Z = (score - mean)/sd
-1.75 = (x - 38)/4
Multiply both sides by 4:
-7 = x -38
Add 38 to both sides:
x = 31
He scored a 31 points on the exam
Answer:
x=-7
Step-by-step explanation:
x-y=-10
x=-10+y
(-10+y)-6y=-25
-10+y-6y=-25
-5y=-15
y=3
x-3=-10
x=-7
Answer:
2
Step-by-step explanation:
Plug in x=0
p(x)=6x^4+2x^3-x+2 at x=0
p(0)=6(0)^4+2(0)^3-(0)+2
p(0)=2

Answer:
6000 mL
Step-by-step explanation:
The prefix "milli-" is an SI standard prefix meaning 1/1000. So, 1 mL = (1/1000)L.
When doing dimension changes, you always want to use scale factors that have a value of 1, which is to say the numerator is equal to the denominator. For converting liters to milliliters, the scale factor you want will have mL in the numerator and L in the denominator:
(1 mL)/(1/1000 L) or (1000 mL)/(1 L)
To do your conversion, multiply your liter volume by this factor.
6 liters is 6000 milliliters.
__
You will notice that the dimensions "L" cancel, which is the point of the exercise.
_____
<em>Additional comment</em>
6 L is closer to 202.884 fluid ounces. The conversion factor is ...
Answer:
$57 interest
Step-by-step explanation:
For an interest rate of 19% ; the monthly interest will be 19/100 = 0.19
4 months interest will be (0.19 * 4)/12 = 0.0633
so now, the value of the interest will be
0.0633 * 900 = $57
