$21.03 you would have to subtracts the 10% first then subtract 15%
Answer:
<u>D</u>, R: {11, -4, -29}
Step-by-step explanation:
According to the given set of domains, the corresponding range is found by substituting the x values into the equation and solving for y.
i.e {-2} -> 5x + y = 1, -10 + y = 1, <u>y = 11</u>
{1} -> 5x + y = 1, 5 + y = 1, <u>y = -4</u>
{6} -> 5x + y = 1, 30 + y = 1,<u> </u><u>y</u><u> </u><u>=</u><u> </u><u>-</u><u>2</u><u>9</u>
Answer:
p(s) = 0,33
Step-by-step explanation:
n = 450
p₀ = 150/450 p₀ = 0,33 then q₀ = 0,67
n*p₀ = 0,33*450 = 150
n*q₀ = 0,67*450 = 301
n*p₀ and n*q₀ more than 10, we can approximate the binomial to a Normal Distribution Distribution
a) p - p₀ = z(c) * √ (p₀q₀)/n
z(c) = ??
CI 95 % then α = 5 % α = 0,05 α/2 = 0,025
z(c) = 1,96
p = p₀ ± z(c) * √ (p₀q₀)/n
p = 0,33 ± 1,96 * 0,022
p = ( 0,33 - 0,04 ; 0,33 + 0,04
p = ( 0,29 ; 0,37 )
The value of the center of the confidence Interval is 0,33
p(s) = 0,33
Answer: A(108)
Step-by-step explanation:
x is x while y=x-12
x+x-12=24
=> 2x=36
=> x=18
y=18-12=>6
18*6= 108
Have a nice day! :)
24 of the 30 students surveyed liked history.
24/30 = 0.8 = 80% of the students surveyed liked history.
Multiply total students by 80%
625 x 0.8 = 500
500 of the total students like history.
