3. i) Determine the volume of the cylinder above to the nearest cubic centimetre. (3 points)
Answers
Answer:
1480cm³
Step-by-step explanation:
The Equation for the Volume of a Cylinder is V=Bh, where B is the area of the circle (A= πr²).
We are given all of the things we need, we just have to plug them into the equation.
First let's find B using the radius(r) which is given to be 6.4cm, so B=πr²
B=π(6.4cm)²
Plug that into a calculator to get 128.6796351cm²
Now we can plug that into the original equation, V=Bh.
V=(128.6796351cm²)h
h is also given to be 11.5cm, so lets plug that in.
V=(128.6796351cm²)(11.5cm)
You will get V=1479.815804cm³, but since we are rounding to the nearest cubic centimeter, we would round up to 1480cm³.

An air-conditioning repair technician claims to complete 67% of repairs in under an hour. A random sample of 31
repairs was chosen, and 22 of those were completed in under an hour. Let p = the proportion of the random
sample that were completed in under an hour.
The probability that 71% or more of this technician's repairs were completed in under an hour is 0.317. Does this
result provide convincing evidence against the technician's claim?
Yes, it is expected that 22 of the units at most will be repaired in under an hour.
Yes, the probability of seeing the sample result is so far from what is expected that the probability of it occurring by
chance alone is very unlikely.
No, there is a very small chance of seeing the sample result. It is unlikely to occur by chance alone.
No, the difference between the sample result and what is expected is not extreme enough. The probability of it
occurring by chance alone is not unlikely.

Answers
Answer:
[tex]y=\frac{3}{5} x+\frac{7}{5}[/tex]
Step-by-step explanation:
1) the equation of the given line in the slope-interception form is:
y= 3/5 x -2;
the equation of the required line is
y=slope*x+i;
2) if the required line is parallel to the given one, it means, the value of its slope is the same, it means 3/5;
then the equation of the required line is
y=3/5*x+i;
3) if the point (-4;-1) belongs to the required line, then it is possible to substitute its coordinates into the equiation of the required line
-1= 3/5*(-4)+i;
4) it is possible to calculate the value of 'i':
i=7/5;
5) if slope=3/5, i=7/5, then the required equation of the line in slope-interception form is:
[tex]y=\frac{3}{5} x+\frac{7}{5}.[/tex]
What is the equation of the line?
A. y= 1/3x - 1
B. y= -1/3x + 1

(10 A person flying a kite has released
123 ft of string. The string makes an
angle of 21 degrees with the ground. How high
is the kite ?
Answers
Answer:
The kite is about 44.1 feet high.
Step-by-step explanation
Since you are trying to find the height, you would draw a triangle to diagram which sides you need to use. The 123 ft of string would be the hypotenuse of the triangle while the 21 degrees is the theta. You are trying to find the height and from the theta that would be the opposite side so you would use sine because you are using opposite and hypotenuse.
sin21=x/123
You have sin of 21 because that is the angle measure, then opposite over hypotenuse which is x/123.
You then multiply both sides by 123 to get the variable of x alone on one side.
123sin21=x
Then just plug this into your calculator and round to the nearest tenth and you get 44.1 feet.
