A medical website states that 40% of U.S. adults are registered organ donors. A researcher believes that the proportion is too h
alexgriva [62]

Answer:

Pvalue = 0.193

There is not enough evidence to conclude that the proportion of registered organ donors is less than 40%

Step-by-step explanation:

H0 : p = 0.4

H1 : p < 0.4

Test statistic :

z=pˆ−p/√p(1−p)/n

pˆ = 74 / 200 = 0.37

Z = (0.37 - 0.40) / √(0.40(1 - 0.40) / 200

Z = - 0.03 / √0.0012

Z = - 0.03 / 0.0346410

Z = - 0.866

Test statistic = -0.866

The Pvalue :

P(Z < -0.866) = 0.193

α - level = 0.05

If Pvalue < α ; Reject H0

Since Pvalue > α ; There is not enough evidence to conclude that the proportion of registered organ donors is less than 40%

Jayden earned some money doing odd jobs last summer and put it in a savings account that earns 12% interest compounded monthly.
aivan3 [116]

Answer:

$220.18

Step-by-step explanation:

The amount A(n) accrued for P dollars saved at r% annual interest for a period of n years compounded k times is derived using the formula:

A(n)=P \left(1+\dfrac{r}{k}\right)^{nk}

In Jayden's case:

  • A(n)=$400
  • r=12%=0.12
  • n=5 years
  • k=12 Months

We want to determine the amount Jayden put in the savings account.

400=P \left(1+\dfrac{0.12}{12}\right)^{12*5}\\400=P \left(1+0.01}\right)^{60}\\400=P \left(1.01}\right)^{60}\\P=\dfrac{400}{\left(1.01}\right)^{60}}\\

P=\$220.18

Jayden earned $220.18 from doing odd jobs.

Let θ (in radians) be an acute angle in a right triangle, and let x and y, respectively, be the lengths of the sides adjacent an
Fed [463]
Explanation is given step by step just below:
tan(theta(t))=y(t)/x(t)

differentiate
sec^2(theta(t))*theta'(t)=y'(t)x(t)-y(t)x'(t)/x^2(t)
thus
theta'(t)=(y'(t)x(t)-y(t)x'(t))
divided by (x^2(t)*sec^2(θ(t))
