Answer:
110 = z
Step-by-step explanation:
Since these figures are similar, the angles have to be the same measure
<A =< E
<B = < F
<C = <G
<D = <H
110 = z
Answer:
{x,y} = {8,3}
Step-by-step explanation:
// Solve equation [2] for the variable y
[2] 4y = 2x - 4
[2] y = x/2 - 1
// Plug this in for variable y in equation [1]
[1] 3x - 4•(x /2-1) = 12
[1] x = 8
// Solve equation [1] for the variable x
[1] x = 8
// By now we know this much :
x = 8
y = x/2-1
// Use the x value to solve for y
y = (/2)(8)-1 = 3
The annual salaries at a particular company are approximately normally distributed with a mean is 0.42124
Manufacturing job :
Mean (m) = 40,000
Standard deviation (s) = 9000
Sales job :
Mean (m) = 35000
Standard deviation (s) = 9000
Probability of earning more than 45000 if one or the other job is selected;
Obtaining the standardized scores and probability for each :
Z = (x - m) / s
P(x > 45000)
Z = (45000 - 40000) / 9000 = 0.5555
= 0.56
P(Z > 0.56) = 0.28774(Z probability calculator)
For sales
P(x > 45000)
Z = (45000 - 35000) / 9000 = 1.1111111
= 1.11
P(Z > 1.11) = 0.1335 (Z probability calculator)
0.28774 + 0.1335 = 0.42124
