Answer:
Using the slope-intercept form, the slope is −4
Step-by-step explanation:
Answer:
The interpretation of that same problem is listed throughout the section below on explanation.
Step-by-step explanation:
<u>Interpretation:</u>
- Researchers seem to be confident with 95% that the sample selection standard error seems to be + as well as - 4 percent respectively.
- This same margin of sampling error would then decrease from either the mean or average value by four percentage points smaller or even larger, it describes the survey method.
So that the above is the right answer.
The blank is 25.
Tip: There is already 25, so there is only 50. But they want half so, half of 50 is 25.
I hope you understand.
Answer:
dimension are 350 m and 350 m and
area is 122500 m²
Step-by-step explanation:
Given data
perimeter is 700 m
to find out
the largest area and its dimensions
solution
we consider x and y are the sides
so area is xy
perimeter is 2x+ y = 700
so we can say y = 700 -2x
so area will be = x (700 - 2x)
area = 700x - 2x²
we take derivative here and equal to zero
dA/dt = 700x - 2x²
700 - 4x = 0
x = 700/4
x = 175
so will be
y = 700 -2x
y = 700 -2(175)
y = 350
so dimension are 350 m and 350m
area is 122500 m²
Answer:
60.5 milligrams per square centimeter First, determine how many half lives have expired by dividing the time by the half-life. So: 55/20 = 2.75 That means that only 2^(-2.75) = 0.148650889 = 14.8650889% of the original substance remains. So just divide the amount remaining by 0.148650889 to get the original amount. 9 / 0.148650889 = 60.5445419 So originally, there was 60.5 milligrams per square centimeter 55 years ago.
