Answer:
C) $17.36
Step-by-step explanation:
As Jay Stone earns $280 a week as gross weekly pay which is the amount he earns before taxes are deducted and you know that the rate is 6.2%, you can calculate the amount that is deducted from his pay this week for Social Security taxes by finding the 6.2 percent of his gross weekly pay:
$280*6.2%= $17.36
According to this, the amount that is deducted from his pay this week for Social Security taxes is $17.36.
Answer:
5 ; 0.728 ; 0.00002
Step-by-step explanation:
According to the Central limit theorem, for a normal distribution, the population mean equals the sample mean., Hence the population mean, μ = sample mean = 5
The standard deviation of sampling distribution :
Standard deviation / sqrt(n)
σ / sqrt(n)
σ = 3 ; n = 17
3 / sqrt(17)
3 / 4.1231056
= 0.7276
= 0.728
3.)
P(x < 2) :
Using :
Z = (x - mean) ÷ s/sqrt(n)
P(x < 2) = (2 - 5) ÷ 3/sqrt(17)
P(x < 2) = -3 / 0.7276068
P(x < 2) = - 4.1231060
Z < - 4.123 = 0.00002 (Z probability calculator).
Answer:
Step-by-step explanation:
p(x)=(x-2)²(x+3)³(x-4)
degree=6
degree =number of zeros
2.6 gallons per hour x 16 hours = 41.6 gallons
Answer:
14
Step-by-step explanation:
We can use the Pythagorean theorem since this is a right triangle.
a^2 +b^2 = c^2
where a and b are the legs and c is the hypotenuse
x^2 + 48^2 = 50^2
x^2 +2304=2500
Subtract 2304 from each side
x^2 +2304-2304=2500-2304
x^2 =196
Take the square root of each side
sqrt(x^2) =sqrt(196)
x =14
