Answer:

9.8

Step-by-step explanation:

Accordinng to the question,A bicyclist travelled for T = 0.7 hours at a constant speed of R = 14 kilometers (km) per hour. Use the formula D = R · T to find the total distance traveled in kilometers. Do not include the units in your answer.

We all know that speed= distance/ time and if you cross multiply,we will have distance as Time × Speed.

But since we were told to use D= R • T

And D is the distance

T is the time which is 0.7

R is the speed which is 14 kilometers per hour

Therefore, the total distance traveled by the cyclist is 14 × 0.7 = 9.8

Answer:

9.8

Step-by-step explanation:

We have the following formula:

D = R \times T

We have that:

R = 14, T = 0.7

So

D = 14*0.7 = 9.8

The total distance traveled in kilometers is 9.8

A poll found that 52% of U.S. adult Twitter users get at least some news on Twitter. The standard error for this estimate was 2.
Leya [2.2K]

Answer:

The 99% confidence interval for the fraction of U.S. adult Twitter users who get some news on Twitter is (0.46, 0.58). This means that we are 99% sure that the true proportion of all U.S. adult Twitter users who get some news on Twitter is between these two values.

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of \pi, and a confidence level of 1-\alpha, we have the following confidence interval of proportions.

\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}

In which

z is the z-score that has a p-value of 1 - \frac{\alpha}{2}.

A poll found that 52% of U.S. adult Twitter users get at least some news on Twitter. The standard error for this estimate was 2.4%

This means that:

\pi = 0.52, \sqrt{\frac{\pi(1-\pi)}{n}} = 0.024

99% confidence level

So \alpha = 0.01, z is the value of Z that has a p-value of 1 - \frac{0.01}{2} = 0.995, so Z = 2.575.

The lower limit of this interval is:

\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.52 - 2.575(0.024) = 0.46

The upper limit of this interval is:

\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.52 + 2.575(0.024) = 0.58

The 99% confidence interval for the fraction of U.S. adult Twitter users who get some news on Twitter is (0.46, 0.58). This means that we are 99% sure that the true proportion of all U.S. adult Twitter users who get some news on Twitter is between these two values.

The formula for the area of a circle is:
π*radius^2

Input the information we already know:
π*5^2
Follow BEDMAS
π*25
=78.5398163
Since half of the circle is shaded, divide the area by 2
78.5398163/2
=39.2699081
The area of the shaded sector is 39.2699081 meters²

line m passes through point (-2,-1) and is perpendicular to the graph of y=-2/3x+6. Line n is parallel to line m and passes thro
puteri [66]

Answer:

Hello...... here is a solution :

1 -  

Hello:

the   equation of "m" is : y = ax+b

the slope is a : a×(- 2/3) = -1......( perpendicular to a line : y=-2/3x+6 when the slope is -2/3 )

a = 3/2          

the line " n" that passes through (4, - 3) and  parallel to line "m" :  

when the slope is 3/2 ( same slope )

the equation in slope-intercept form of the line" n" is :

 y – (-3)= (3/2)(x – 4)
