Answer:
Percentage decrease ( from $4.09 to $3.59) is 0.1% ( Rounded to nearest tenth)
Percentage increase (from $3.59 to 4.09) is 0.1% ( Rounded to nearest tenth)
Percentages are not same for the both price changes. As we can see from the calculations percentage change from $3.59 to $4.09 is higher.
Step-by-step explanation:
$4.09 has been changed to $3.59.
Percent change = [(Value after - Value before) / Value before]*100
=%
=%
=%
=% ( Rounded to nearest tenth)
Percentage decrease is 0.1% ( Rounded to nearest tenth)
Now lets calculate the percentage change from $3.59 to $4.09.
Percent change = [(Value after - Value before) / Value before]*100
=%
=%
=%
=% ( Rounded to nearest tenth)
Percentage increase is 0.1% ( Rounded to nearest tenth)
Percentages are not same for the both price changes. As we can see from the calculations percentage change from $3.59 to $4.09 is higher.
The probability of getting a cookie with no more than 3 chips is 0.714.
<h3>What is probability?</h3>It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.
We have:
Well-mixed cookie dough will produce cookies with a mean of 6 chocolate chips apiece.
Using poison ratio:
λ is the mean number of chocolate chips in a piece
P(X ≥ 5) = 1 - P(X < 5)
P(X ≥ 5) = 1 - P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4)
After solving;
P(X ≥ 5) = 0.714
Thus, the probability of getting a cookie with no more than 3 chips is 0.714.

Answer:
Step-by-step explanation:
We need to find an algebraic expression for the given statement i.e. "the quotient of negative eight and the sum of a number and three".
Let the number be x. Quotient means to divide. It means we need to divide -8 and the sum of x and 3.
So, we can write it as follows :
Hence, this is the required solution.
