X > ---------------------------------------

blondinia [14]

Answer:

x > 14

Step-by-step explanation:

Since 24 > 20, the included angle opposite to side length of 24 will be greater than the included angle that is opposite to side length 20, this is based on the Converse of the Hi nge Theorem.

Therefore,

2x + 6 > 34

2x + 6 - 6 > 34 - 6

2x > 28

2x/2 > 28/2

x > 14

find the volume of a right circular cone that has a height of 2.1m and a base with a diameter of 13.7m. round your answer to the

Nikolay [14]

Answer:

Volume of the cone = 103.14 meter cube

Step-by-step explanation:

Height of the cone= 2.1 m

Diameter= 13.7 m

Radius= 13.7/2= 6.85 m

Volume of a cone :

$=\pi r^2\frac{h}{3}$

As, $\pi =\frac{22}{7}=3.14$

Putting the values in the formula:

Volume is :

$=3.14*(6.85*6.85)*\frac{2.1}{3} \\\\=3.14*(6.85*6.85)*0.7\\\\=3.14*46.92*0.7\\\\=3.14*32.85\\\\=103.14m^3$

The volume of the cone is 103.14 meter cube

A poll of a random sample of1400 adults reported that respondents slept an average of 6.5 hours on weekdays and 7.2 hours on we

stich3 [128]

Answer:

b) Dependent sample

Step-by-step explanation:

Given:

Sample size, n = 1400

The average sleep of the respondents in weekdays = 6.5 hours

The average sleep of the respondents in weekends = 7.2 hours

% with eight or more hours of sleep on weekdays = 20%

% with eight or more hours of sleep on weekends = 43%

Required: To Check if the samples on weekdays and weekends are independent or dependent.

When samples are independent, it means one sample does not influence the other and vice versa, while samples are said to be dependent if the outcome of one test influences the outcome of the other. The tests might be from a similar population or from various populations.

In this case, the sample gathered are from similar population because same sample is used for both weekdays and weekends. Therefore, we can say the sample is a paired sample.

The samples on weekdays and weekends are dependent since same people are used, also since sleep on weekdays and sleep on weekends may influence each other.
