Dvinal [7]

Answer:

b. Do not reject H0. We do not have convincing evidence that the mean weekly time spent using the Internet by Canadians is greater than 12.7 hours.

Step-by-step explanation:

Given that in a study of computer use, 1000 randomly selected Canadian Internet users were asked how much time they spend using the Internet in a typical week. The mean of the sample observations was 12.9 hours.

H_0: \bar x =12.7\\H_a: \bar x >12,7

(Right tailed test at 5% level)

Mean difference = 0.2

Std error = \frac{6}{\sqrt{1000} } \\=0.1897

Z statistic = 1.0540

p value = 0.145941

since p >alpha we do not reject H0.

b. Do not reject H0. We do not have convincing evidence that the mean weekly time spent using the Internet by Canadians is greater than 12.7 hours.

RATE is a quadrilateral inscribed in the above circle with arc measures shown above. What is the measure of the smallest angle i
Sav [38]

Answer:

The measure of the smallest angle is 77°

Step-by-step explanation:

* Lats study some facts about the circle

* In any circle; If the vertices of a quadrilateral lie on its

 circumference then the quadrilateral is called a cyclic quadrilateral

- In any cyclic quadrilateral each two opposite angles are supplementary

 that means their sum = 180°

* In any circle; if the vertex of an angle lies on the circumference

 is called an inscribed angle

- The inscribed angle subtended by the opposite arc

- The measure of the inscribed angle = 1/2 the measure of

  the subtended arc

* Now we can solve our question

∵ R , A , T , E all on the the circumference of the circle

∴ RATE is a cyclic quadrilateral

∵ Angle RAT is an inscribed angle subtended by arc RET

∵ The measure of arc RE = 121°

∵ The measure of arc ET = 51°

∴ The measure of arc RET = 121 + 51 = 172°

∵ m∠RAT = (1/2) measure of arc RET

∴ m∠RAT = (1/2) × 172 = 86°

∵ Angle ATE is an inscribed angle subtended by arc ARE

∵ The measure of arc AR = 85°

∵ The measure of arc RE = 121°

∴ The measure of arc ARE = 85 + 121 = 206°

∵ m∠ATE = (1/2) measure of arc ARE

∴ m∠ATE = (1/2) × 206 = 103°

* Now lets find the remainder angles by using cyclic quadrilateral

∵ RATE is a cyclic quadrilateral

∴ m∠RAT + m∠RET = 180°

∵ m∠RAT = 86°

∴ m∠RET = 180 - 86 = 94°

* Similar;

∵ RATE is a cyclic quadrilateral

∴ m∠ATE + m∠ARE = 180°

∵ m∠ATE = 103°

∴ m∠ARE = 180 - 103 = 77°

* The measure of the smallest angle is 77°
