2/15 so 13.3% ?
I’m not entirely sure if this is right but I think it’s getting there...
Answer:
9
Step-by-step explanation:
f(x) = -x^2
f(3) = -3^2
f(3) = 9
Answer:
145 yd²
Step-by-step explanation:
There will be dour triangular faces. For a triangle, area is given as
A=½bh where b is base and h is height. The base will be 5 yards and h is 12 yards hence for one triangular face, area will be ½*5*12=30 yd²
Since they are four similar triangles, area of triangular faces will be 30*4=120 yd²
The surface area of a square base is given by
A=a*a=a² where a is the dimension of one side. Given that the meaurement is 5 yards then A=5²=25 yd²
Total area will be the sum of triangular and square faces hence 120+25=145 yd²
Answer:
The asnwer is 83.6 :)
Step-by-step explanation:
7.6x11=83.6
Answer: standard deviation
is a measure of the amount of variation or dispersion of a set of values.[1] A low standard deviation indicates that the values tend to be close to the mean (also called the expected value) of the set, while a high standard deviation indicates that the values are spread out over a wider range.The standard deviation of a random variable, statistical population, data set, or probability distribution is the square root of its variance. It is algebraically simpler, though in practice less robust.The standard deviation is given by the formula: s means 'standard deviation'. S means 'the sum of'. Now, subtract the mean individually from each of the numbers given and square the result.
Step-by-step explanation :percentage area
i've never really heard of this but my sister just breifed me and this is what i could get
to calculate percentage area Find the percentage of a portion of an object by dividing the area of the portion by the area of the whole original object. Multiply the length times the width of the original piece to calculate its area in square inches, feet or centimeters
i hope it hrlps please mark me brainliest :)
