The rectangle they created has an area of 20*36=720
but you need to subtract the half circle area so use pi * r ^2
pi(18)^2pi = 324pi
half this area for the circle because only half of the circle is in the rectangle area we found.
so then 720 - (162pi) = blue shaded area

Area of the rectangle:720
area of half circle:254.34
720-254.34=465.66

Match each value with its formula for ABC.

Ivahew [28]

For the triangle ABC use the sine theorem:

$\dfrac{a}{\sin A}= \dfrac{b}{\sin B}= \dfrac{c}{\sin C}$ .

1. From $\dfrac{a}{\sin A}= \dfrac{b}{\sin B}$ you have $\dfrac{a}{b} \cdot \sin B=\sin A$ .

2. From $\dfrac{b}{\sin B}= \dfrac{c}{\sin C}$ you have $\dfrac{b}{c} \cdot \sin C=\sin B$ .

3. From $\dfrac{a}{\sin A}= \dfrac{c}{\sin C}$ you have $\dfrac{c}{a} \cdot \sin A=\sin C$ .

4. From $\dfrac{a}{\sin A}= \dfrac{c}{\sin C}$ you have $\dfrac{\sin A}{\sin C} \cdot c=a$ .

5. From $\dfrac{a}{\sin A}= \dfrac{b}{\sin B}$ you have $\dfrac{\sin B}{\sin A} \cdot a=b$ .

6. From $\dfrac{b}{\sin B}= \dfrac{c}{\sin C}$ you have $\dfrac{\sin C}{\sin B} \cdot b=c$ .

A random sample of 11 nursing students from Group 1 resulted in a mean score of 41.3 with a standard deviation of 6.8. A random

Lina20 [59]

Answer:

At 1% significance level, this difference is considered to be extremely statistically significant.

Step-by-step explanation:

Group Group One Group Two

Mean 41.300 54.800

SD 6.800 6.000

SEM 2.050 1.604

N 11 14

H0: Mean of group I = Mean of group II

Ha: Mean of group I < mean of group II

(Left tailed test at 1% significance level)

The mean of Group One minus Group Two equals -13.500

standard error of difference = 2.563

t = 5.2681

df = 23

p value= 0.00005

Since p < significance level, reject H0
