Answer:
2/3 ( 8 + y ) + 4 r
Step-by-step explanation
2/3 is the two thirds
The sum of 8 and y is 8 + y
So, two thirds of the sum of 8 and y is 2/3 ( 8 + y )
Then, the product of 4 and r is 4 r
Therefore; Two-thirds of the sum of 8 and y plus the product of 4 and r is 2/3 (8 + y) + 4 r
Answer:
Step-by-step explanation:
We know that half of the students has two pets. The rest of the students make up the other half. So, we have 3 students + 2 students + 8 students = 13 students that make half of the sample population
That means total number of students being surveyed is 13+13=26 students
Then we work out the probability
P(One pet) = 8/26 = 4/13
P(Two pets) = 1/2
P(Three pets) = 3/26
P( Four pets) = 2/26 = 1/13
The probability distribution is shown in the table below. Let be the number of pets and is the probability of owning the number of pets
The answer is -26 because you have to use pemdas you multiply the numbers in an parentheses and then go from left to right adding or subtracting.Like in the picture
C DAnswer:
Step-by-step explanation:
BOTH NUMBERS ARE LESS BECAUSE THEY ARE FURTHER FROM 0 ON THE NEGATIVE END
For the first day we have the following function:
f (n) = (0.3 * 10) n + 8
For the second day we have the following function:
f (n) = (0.4 * 10) n + 5
You spent the same amount of money as the day before:
(0.3 * 10) n + 8 = (0.4 * 10) n + 5
3n + 8 = 4n + 5
n = 8-5
n = 3 items
We evaluate each function for n = 3
f (3) = (0.3 * 10) * 3 + 8 = 17 $
f (3) = (0.4 * 10) * 3 + 5 = 17 $
The total amount of money is:
17 + 17 = 34 $
Answer:
you purchase 6 items
you spend at the craft store during the sale $ 34
