The probability is low.
20% of 9 is 2. Therefore, the probability is low that 5 out of the 9 students drive cars.
Answer:
6 times.
Explanation:
Since she served 3 salads that contain 2/3 cup of blueberries each, and her measuring cup only holds 1/3 cup, she'll have to measure the blueberries 6 times in total, doing 2 measurements per salad (2 x 1/3 = 2/3). Since 2 x 1/3 cup is 2/3 cup, and there are 3 salads in total (multiply 2 measurements by 3 salads), this means she measures the blueberries 6 times.
How many slices each person gets
Answer:
Option B, 8/5 hr
Step-by-step explanation:
1/2 + 1/8
1*4 / 2*4 + 1/8
4/8 + 1/8
5/8 = 1/t
5t / 5 = 8 / 5
t = 8/5
Answer: Option B, 8/5 hr
The amount of medicine in the bloodstream decreases by 25% each hour.
<h3>Exponential equation</h3>
The standard exponential equation is expressed as:
y = ab^x
a is the initial amount
b is the rate
If b < 1, hence there is a declince
Given the expoenentia equation A(h)=600(0.75)^h,
b = 1 - r = 0.75
r = 1 - 0.75
r = 0.25
This shows that the amount of medicine in the bloodstream decreases by 25% each hour.
