Answer:
$60,000
Step-by-step explanation:
If Ava earns at a constant rate of $3,000 for 1 month, then just multiply $3,000 by how many months she works.
3,000 x 20 = 60,000
If Ava earns $3,000 in one month, she will earn $60,000 in 20 months.
Answer:
The graph touches the x-axis at (–2.5, 0).
Answer:
Step-by-step explanation:
We get to use the simple version of the half life equation:
where N is the amount of radioactive element left after a specific number of years,
N0 is the initial amount of the element,
t is the number of years (our unknown), and
H is the Half life of the element. For us,
N is 61
N0 is 70,
t is unknown,
H is 24 years. Filling in:
. We begin by dividing both sides by 70 to get:
and then take the natural log of both sides:
which allows us to bring down the exponent to the front on the right side:
. We divide both sides by ln(.5) to get:
and then multiply both sides by 24 to get:
t = 4.8 years
so first you find out how many she can bake in 1 hour so you divide 105 and 3 which is 35
so since she bakes 35 cookies and hour you multiply 35 by how many hours she cooks
so 35 x 3 =105 35 x 5=175
Ali cooks 175 cookies in 5 hours
A conclusion which can be derived from these random samples is that: B. the students in grades 11 and 12 scored higher than the students in grades 9 and 10.
<h3>What is a median?</h3>
A median can be defined as the middle number (center) of a sorted data set, which is when the data set is arranged in from the greatest to least or the least to greatest.
In Mathematics, the median of a data set is generally considered to be a better measure of center than the mean when there's an outlier in the data set.
Based on the information provided for these samples, we can logically conclude that the students in grades 11 and 12 scored higher than the students in grades 9 and 10 because a median score of 86 is greater than a median score of 79.
