Answer:
A. 0.4082
Step-by-step explanation:
According to the given data
mean 'μ' =50
standard deviation 'σ'=15
In order to find the probability for 50<x<70
, we use the standard form
Z= (x−μ)
/σ
when x=50, Z will be zero
therefore, Z=0
when x=70,
Z=(70−50)/15
Z= 20/15
Z=1.33
next is to find the probability for 50<x<70
for standard form 0<z<1.33
By using Z-table, the area is equal to 0.4082
Thus, probability that the length of time will be between 50 and 70 hours is 4082
I can't see pictures, but I'm assuming you want it solved.
x+2>7.
Cancel out the 2 by subtracting 2 from both sides.
x+2>7
-2 -2
x>5
So the inequality is x>5.

hope it helps
sorry if it doesn't
Since the square roots are both six and cannot be simplified any more you just treat it like a normal subtraction problem
so -5 - 2= -7
so it would be -7√2
Answer:
32x-24y-7
Step-by-step explanation:
Use the distributive property and multiply 4 by each term in the parentheses. 4 times 8x = 32x and 4 times -6y = -24y.
The inverse function of g(x) will be g⁻¹(x) = (4x + 3) / 2. Then the value of the inverse function, at x = -3, will be 4.5.
<h3>What is inverse of a function?</h3>
Let the function will be
f: X → Y
Then the inverse function will be
f⁻¹: Y → X
The function is given below.
g(x) = (2x – 3) / 4
Then the inverse function of g(x) will be
g⁻¹(x) = (4x + 3) / 2
Then the value of the inverse function, at x = -3, will be
g⁻¹(-3) = [4(-3) + 3] / 2
g⁻¹(-3) = -4.5
