15. Since p=215. 851-p would be 851-215 which equals 636

18. Since a=6 and b=5 and c=3, ab/2 would be 6x5/2 which equals to 30/2. Now, you must add 30/2 to 4c. And again since c=3, it would be 4x3 which equals to 12. So now the equation would be 30/2+12. You must now turn the fraction into a whole number by 30÷2 which is 15. The question would now ask 15+12 so the answer would be 27

Normalmente, el fracaso se asocia con el valor 0 y el éxito con el 1. Se nombra como Be(p), donde p(X=1) = p es la probabilidad de obtener éxito y p(X=0) = q = 1-p la probabilidad obtener fracaso.

Please help me with math thanks

Given that a room is shaped like a golden rectangle, and the length is 29 ft with the ratio of golden rectangle being (1+√5):2, thus the width of the room will be:
ratio of golden triangle=(length if the room)/(width of the room)
let the width be x
thus plugging the values in the expression we get:
29/x=(1+√5)/2
solving for x we get:
x/29=2/(1+√5)
thus
x=(29×2)/(1+√5)
answer is:
x=58/(1+√5)
or
byrationalizing the denominator by multiplying both the numerator and the denominator by (1-√5)
58/(1+√5)×(1-√5)/(1-√5)
=[58(1-√5)]/1-5
=(58√5-58)/4

Your mathematics teacher asks you to sketch a graph of the exponential function f(x) = (3 / 2)^x for x, a number

noname [10]

I think there is a mistake in the question. If f(x) = (3 / 2)^x

, then

If the scale is 10 units to one inch, then you will need a paper size of 1105733.232 inches!

As a reference, a graph is included in attachments.

To get a linear function 2 points are needed. Assuming the equation g(x) = m*x and taking the points of the aforementioned table, we can compute the slope as

m = (f(x2) - f(x1))/(x2 - x1)

m = (11057332.32 - 1)/(40 - 0)

m = 276434.283

Function g(x) = 276434.283*x pass at points (0, 1) and (40, 11057332.32). h(x) = 276434.283*x + 2 fulfill the requirement that h(x) is greater than f(x), for all x such that 0 ≤ x ≤ 40, but f(41) > h(41), because at the next point, the exponential function will growths faster than linear function (see figure).
