Answer:
Step-by-step explanation:
so the steps to doing this are as follows :
Subtract the accepted value from the experimental value.
Take the absolute value of step 1.
Divide that answer by the accepted value.
Multiply that answer by 100 and add the % symbol to express the answer as a percentage.
|18.7-19.3|/19.3 = 0.031088 * 100% = 3.1%
the total number of out comes would be 16^2 or 256.
some extra things...
A numbered card from 1 - 10 would be 1 over 10 or 10% chance of picking correctly.
a number cube from 1 - 6 would be 1 over 6 or 16.66% chance of picking correctly.
if you want to combine these and pick one from both, it becomes 1 over 16 or 6.25% chance of picking both correctly.
Answer:
No its nonportional
Step-by-step explanation:
proportional relationship doesn't have any operation between the “k” and “x” where K is the unit rate or the constant of proportionality.
I think it’s number 4 not sure though
Answer:
x=22
The measure of the angle 2x-10 is 34 degrees.
The measure of the angle 3x-10 is 56 degrees.
Step-by-step explanation:
What you first want to do is add both of the equations up so that they equal 90 which would look like 2x-10+3x-10=90 next add up all like terms to get 5x-20=90. Now you want to add 20 on both sides to get 5x by itself which leaves you with 5x=110. Now you want to isolate x by dividing by 5 on both sides to finally get x=22.
To find the measure of the other two angles you want to simply plug in 22 as the value of x in each so you get 2(22)-10=34 and 3(22)-10=56.
