Answer:
15 marbles in a jar.
Step-by-step explanation:
y · 200 = 3000 · 1
200y = 3000
200y ÷ 200 = 3000 ÷ 200
y = 15
15) It can't be an exponential or logarithmic function because the function increases and decreases. Exponential functions always only increase or decrease. Logarithmic functions always increase until they reach a carrying capacity, where it then stabilizes.
16) You can find the minimum possible degree polynomial by finding how many times the graph touches the x-axis. In this graph, it touches the x-axis 3 times, but the graph kind of makes a parabolic shape at x=7, so you would have to count that as touching the x-axis 2 times. Therefore, the answer is a 4th degree polynomial.
17) The x-intercepts are when the graph touches the x-axis. It touches the x-axis at x=0, 7, and 12. This means that the population of the insects is 0 when at the beginning of the 12 month period, after 7 months, and after 12 months.
Answer:
469
Step-by-step explanation:
Substitute -5 and -3 into the equation:
-7(8 (-5) + 9 (-3)
-7(-40 - 27)
-7(-67)
+469
Answer:
The estimated gain in score for a student who is given an additional 32 minutes on the exam is 16.96
Step-by-step explanation:
The estimated regression prediction is given by:
Where x denotes the time
y denotes the average score
A)
Substitute x = 98
B)
Substitute x = 129
C)
Substitute x = 159
D)the estimated gain in score for a student who is given an additional 32 minutes on the exam.
So, the estimated gain in score for a student who is given an additional 32 minutes on the exam is 16.96
