Surface area of square pyramid having square base side = 10 cm and slant height = 20 cm is 340 square meters
<u>Solution:</u>
Given that
Shape of the roof is square pyramid.
Base length of square pyramid roof = 10 meters
Slant height of square pyramid roof = 12 meters
Need to calculate the surface area of the roof
Where s is side of square base and l is slant height.
In our case s = 10 meters and l = 12 meters
On substituting the given values in formula we get
Surface area of square pyramid 
Hence surface area of square pyramid having square base side = 10 cm and slant height = 20 cm is 340 square meters.
Yes because 3×2=6 and 1×3=3
Answer:
a) Check graph
b)Closer to 0.5
c)Researcher 1 is right.
Step-by-step explanation:
a) Please check attached graph.
b) Please check second graph. It is shown that the value is 0.387 which is closer to 0.5.
c) Normal distributions are important in statistics and are often used in the natural and social sciences to represent real-valued random variables whose distributions are not known. The researcher 1 is right because there are numerous random variables are exist for this event and normal distribution function is the best function that gives less error for this numerous not-known random variables.
Answer:
A, m < $69.43
Step-by-step explanation:
(Could be wrong, I'm just browsing through brainly and thought it looked easy)
I found the percentage of what they've raised by doing 552.5 * .12 (12 percent of 552.5)
This gave me 66.3
We now need to look for how much they need to raise, so you subtract 552.5 by 66.3 to get 486.2.
You need to find out how much each of the 7 members needs to raise to get 486.2, to do this divide 486.2 by 7 to get 69.45.
Ideally, they would raise just this amount and the correct answer would be an equal sign, but since that isn't an option and if they raised less than 69.45 individually they would fail, raising more than 69.45 would pass their goal. So A, more than 69.45 is the answer.
