The greatest common divisor is 8
Answer:
84%.
Step-by-step explanation:
Let X be the time in minutes for a student chosen at random to finish the test. .
The probability that a student chosen at random finishes the test in less than 48 minutes will represented as
.
<h3>Method 1: technology</h3>
Evaluate the cumulative normal probability on a calculator, where
- The lower bound is 0,
- The upper bound is 48,
- The mean ,
- The standard deviation
.
<h3>Method 2: z-score table</h3>
.
.
Look up the entry that corresponds to on a z-score table: 0.8413.
In other words,
.
The area of this shape is 12.
Area of a triangle = 1/2 x bh
b= base
h = height
So,
1/2 (6)(4)=12
Hope this helps!
Answer:
a) Exponential decay
b,) The parent function is shifted up 1 unit.
Step-by-step explanation:
Assuming your function is
Then we can compare this to:
If
then y is an exponential decay function.
If |b|>1, then y is an exponential growth.
We can see that:
Therefore the given function is an exponential decay.
The parent function is shifted up 1 unit.
Formula of surface area of a sphere is 4
.
Hence it is 4
