Answer: 2.46
Step-by-step explanation:
Formula for x-score is given by :-
, where = Sample mean , = population mean, = population standard deviation, n= sample size.
As per given , n=10
= $29,056
= $3,339
= $31,650
Then,
Hence, the z-score = 2.46
Answer:
tan∅ = 3√29/10
Step-by-step explanation:
Pythagorean Theorem: a² + b² = c²
cos∅ = adjacent/hypotenuse
Since we are given cos∅ = 10/19, we know that one leg is 10 and the hypotenuse is 19. We need to find the missing leg length:
10² + b² = 19²
b² = 19² - 10²
b = √261
b = 3√29
We know that tan∅ equals opposite over adjacent. Our adjacent is given to us by cos∅, so we simply plug in our values:
tan∅ = opposite/adjacent
tan∅ = 3√29/10
Answer:
33
Step-by-step explanation:
46/22=46+23/x
46x=22 times 69
46x=1518
x=33
Answer:
t =
Step-by-step explanation:
solve for t
h = -a + 1; multiply both sides by -2
-2h = a - 2; add 2 to both sides
-2h + 2 = a; divide by a
(-2h + 2) / a = ; take the square root
t =
To find the area, divide the figure in 2. (rectangle and triangle.) For the area of the rectangle, you would do 6*12=72. For the triangle you would do 12*10/2=60. So then you add 72 and 60 to get an answer of 132ft squared.
