Answer:
60
Step-by-step explanation:
15 times 5 is 75 75 minus 15 is 60 so the answer is 60
A) Find the Sum of the X values: 4 +5+8+9+13 = 39
B) Find the Sum of the Y values: 23 +12 +10 +9 +2 = 56
C) Find the Sum of x^2: 4^2 + 5^2 + 8^2 + 9^2 +13^2 = 355
D) The sum of the Y^2's: 23^2 + 12^2 + 10^2 + 9^2 + 2^2 = 858
E) Sum of x *y's: 4*23 + 5*12 + 8*10 + 9*9 + 13*2 = 339
N = number of sets = 5
Numerator of r = (E - A*B/N) = 339-39*56/5 = 339 - 436.8 = -97.8
Denominator of r = SQRT(C-A^2/N) x SQRT(D-B^2/N) =
SQRT(355-39^2/5) x SQRT(858-56^2/5) =
SQRT(50.8) x SQRT(230.8) =
7.1274 x 15.1921 =
108.2803
r = -97.8 / 108.2803
r = -0.903
Answer is A
Given:
Income made last year = $30,000
Tax rate for the first $7000 = 15% = 0.15
Tax rate for the amount over $7000 = 18% = 0.18
Let's find the amount Linda must pay in income tax last year.
To find the amount she must pay, we have:
Tax for first $7000 = 0.15 x 7000 = $1050
Tax for amount over $7000 = 0.18 x (30000 - 7000)
= 0.18 x 23000 = $4140
Therefore, the amount she must pay in income tax is:
T = $1050 + $4140 = $5,190
Linda must pay $5,190 in income tax for last year.
ANSWER:
$5,190
Answer:
x = -6
y = 9
Step-by-step explanation:
The sum of two numbers is 3
x + y = 3
twice the larger number is 36 more than three times the smaller number
2y = 3x + 36
Divide both sides by 2
y = 1.5x + 18
substitute for y in the first equation
x + (1.5x + 18) = 3
2.5x = -15
divide both sides by 2.5
x = -6
Substitute for x in the first equation
-6 + y = 3
y = 9
