Answer:
907.46cm
Step-by-step explanation:
Area of Cirlce = πr^2
R= 17
R^2= 289
289 x 3.14 = 907.46
907.46cm
Given:
The figure of a right angle triangle.
Hypotenuse = 
in.
To find:
The missing lengths of the sides.
Solution:
In the given right angle triangle both legs a and b are equal, and hypotenuse is in.
Using Pythagoras theorem, we get
![[\because a=b]](https://tex.z-dn.net/?f=%5B%5Cbecause%20a%3Db%5D)
Divide both sides by 2.
Taking square root on both sides.
Side cannot be negative. So,
Thus, the missing side lengths are a=9 in and b=9 in.
Therefore, the correct option is C.
Answer:
Solution:
<u>We know that:</u>
- Capacity = 2,500 gallons
- Hose = 25 gallons/minute
Solution:
- 25 gallons = 1 minute
- => 25x gallons = x minutes = 2500 gallons
- => 25x = 2500
- => x = 100 minutes
Hence, it will take 100 minutes to fill the pool.
Answer:
c
Step-by-step explanation:
x^2+5x-14
factor by finding multiples of (-14) that add up to 5
7*-2=-14
7+-2=5
So the factored out equation is (x+7)(x-2)
Therefore the solutions are x=-7 and x=2
Answer:
The data are at the
<u>Nominal</u> level of measurement.
The given calculation is wrong because average (mean) cannot be calculated for nominal level of measurement.
Step-by-step explanation:
The objective here is to Identify the level of measurement of the data, and explain what is wrong with the given calculation.
a)
The data are at the <u> Nominal </u> level of measurement due to the fact that it portrays the qualitative levels of naming and representing different hierarchies from 100 basketball, 200 basketball, 300 football, 400 anything else
b) We are being informed that, the average (mean) is calculated for 597 respondents and the result is 256.1.
The given calculation is wrong because average (mean) cannot be calculated for nominal level of measurement. At nominal level this type of data set do not measure at all , it is not significant to compute their average (mean).
