Hi there!
To solve this problem, we need to first find the amount of red tiles he used by subtracting 50 from 310, and then finding the sum of the two numbers.
310 - 50 = 260
Now, we know that there are 260 red tiles.
3 * 310 = 930
3 * 260 = 780
930 + 780 = 1710
So, the answer is 1710 tiles total.
Hope this helps!
Answer:
0.2916, 0.1488, 0.0319
Step-by-step explanation:
Given that a sign on the pumps at a gas station encourages customers to have their oil checked, and claims that one out of 10 cars needs to have oil added.
Since each trial is independent there is a constant probability for any random car to need oil is 0.10
Let X be the number of cars that need oil
A) Here X is BIN(4,0.1)

B) Here X is Bin (8, 0.1)

C) Here X is Bin (20,5)

Here is the answer as shown in the picture:
Assign x as the number of females.
Since makes are six times more: 6x is the male variable.
In total there are 7x students.
So the fraction for males is : 6/7
There's no way to simplify further because there's no term common to both the denominator/numerator.
Answer: 6/7
Answer:
No because the base could be a different shape.
