Answer:
210
Step-by-step explanation:
we have given significance level α=3% =0.03
level of significance is nothing but the chances of rejecting a null hypothesis by the test when it given that it is correct. it is denoted by α it also defined as the
level of significance =1 - confidence level
now statistically significant test =0.03×7000=210
so the expected value of statistical significant is 210
It would take approximately 11 years for this population to reach 7300.
<h3>How to calculate the time?</h3>
Based on the information provided, the future size of the population can be modelled by using an exponential function:
F = Pe^rt
Substituting the given parameters into the formula, we have;
7300 = 5000e^{0.035 × t}
7300/5000 = e^{0.035t}
1.46 = e^{0.035t}
Taking the ln of both sides, we have:
ln(1.46) = ln(e^{0.035t})
0.378 = 0.035t
t = 0.378/0.035
Time, t = 10.8 ≈ 11 years.

Answer:
a
Step-by-step explanation:
The greatest common factor (GCF) of 21 and 84 is 21.
The GCF is the largest number by which both numbers can be divided. Between 21 and 84, it is 21 because 21/21=1 and 84/21=4.
