Answer:
19
Step-by-step explanation:
45-45-90 triangles always have two legs that are the same length, and a hypotenuse that is the length of the leg times sqrt 2.
Given the position of x, we know it is a leg and must be equal to the other leg, which is 19.
Answer:
b 5/24
Step-by-step explanation:
p(a)=number of times A occurred / number of times trial was repeated
Answer:
87.9
Step-by-step explanation:
Use a calculator or table to find the z-score that corresponds to 25%.
P(Z < z) = 0.25
z = -0.675
Now find the value that corresponds to that z score.
z = (x − μ) / σ
-0.675 = (x − 101.3) / 19.9
x = 87.9
Answer:
x=3y
Step-by-step explanation:
Step 1: flip the equation.
2x−5y=y
Step 2: Add 5y to both sides.
2x−5y+5y=y+5y
2x=6y
Step 3: Divide both sides by 2.
2x
2
=
6y
2
x=3y
Answer:
a= -5
Explanation:
Rewrite the equation to be: 3^a=3^-1 / 3^4
Multiply by adding exponents :))
which would then be 3^a = 3^-5
Then, since the bases are the same then the a would equal negative (-) 5. :))
Hope this helps :)) Plz mark brainlest :))
