Hey there! :)
Answer:
-1/5n + 7 = 2
Start by subtracting 7 from both sides:
-1/5n + 7 - (7) = 2 - (7)
-1/5n = -5
Multiply both sides by the reciprocal of -1/5, or -5.
(-5) · (-1/5n) = (-5) · (-5)
n = 25
Answer:
{0,1,2,3,4,5}
Step-by-step explanation:
We are given that
Total number of machine parts=300
Number of defective machine parts=10
Total number of good machine parts=300-10=290
Sample contain parts that do not conform to customer requirement=5
X is a random variable which is the number of parts in a sample of 5 parts that do not conform to customer requirements.
We have to find the correct answer.
The sample contain 5 parts
Therefore, the possible values of random variable X
0,1,2,3,4,5
Hence, the range of X is given by
{0,1,2,3,4,5}
Answer:
You will be paying $41.30 in total.
Step-by-step explanation:
The cost of the meal is $35 and you want to leave 18% tip on the meal.
We want to find the total amount that will be paid.
First, we have to find 18% of $35 and then, add it to the original bill ($35).
18% of 35 is:
18/100 * 35 = $6.30
The tip is $6.30, therefore, the total amount paid will be:
$35 + $6.30 = $41.30
You will be paying $41.30 in total.
Answer:
9
Step-by-step explanation:
I used tan but there's probably an easier way to do this but 4*tan(20)=8.94 then round it up to 9
It's would be plus haft that number (it's a negative) and the next number would be 0
