Answer:
x=4
Step-by-step explanation:
Since both triangles are similar, you can make an equation 12/5x-2 = 16/6x. When you cross multiply you get 72x=80x-32. Then you transfer the 80x and you get -8x = -32. Then you divide by -8 and you get x=4.
The z-score of the information given is:
z=(x-μ)/σ
where
μ-mean
σ- standard deviation
from the information given:
x=93.02
μ=89
σ=√625=25
hence
z=(93.02-89)/25
z=0.1608
thus
P(X≥x)=1-0.5636=0.4364=43.64%
Answer:
B. 1/16
Step-by-step explanation:
f(-4) = 2^(-4) = 1/(2^4) = 1/16
In this problem, we're going to use the 'PEMDAS' method.
First, we're doing the problem in the parenthesis.
44 - 4 = 40
Next in PEMDAS, we need to do the exponent.
6² = 6 x 6 = 36
Then we would do multiplication, but there is nothing to multiply so we move onto division.
40 / 2 = 20
Now we would add, but there is nothing to add so we move onto subtraction.
20 - 36 = -16
Our final answer would be -16.
Hope this helps!~
Im not sure about 6 but i think 4 is idk
