1. radius = 7 ft, central angle = 18°<br> Find arc length.
Vlada [557]

Answer:

2.2 ft ( to 1 dec. place )

Step-by-step explanation:

The arc length is calculated as

arc = circumference × fraction of circle

     = 2πr × \frac{18}{360}

     = 2π × 7 × \frac{1}{20}

     = 14π × \frac{1}{20}

     = \frac{14\pi }{20} ≈ 2.2 ft

Veronica’s velocity was measured as 4.3 m/s. She displaced 20 meters in 4.7 seconds. Which piece of information is missing for t
Anit [1.1K]

Answer:

Direction is missing

Step-by-step explanation:

Veronica’s velocity was measured as 4.3 m/s. She displaced 20 meters in 4.7 seconds. We know that velocity is a vector quantity. It has both magnitude as well as direction. Velocity is defined as the total distance per unit time I.e.  

                 i.e. the magnitude of velocity is 4.3 m/s  

Here, only velocity is given but its direction is missing. So, the missing information is " the direction ".

Construct a 95% prediction interval for y given x=-3.5, ^y= 2.097x - .552 and se= .976​
Rasek [7]

Answer:

95% Confidence interval for y

= (-9.804, -5.979)

Lower limit = -9.804

Upper limit = -5.979

Step-by-step explanation:

^y= 2.097x - 0.552

x = -3.5

Standard error = 0.976

Mathematically,

Confidence Interval = (Mean) ± (Margin of error)

Mean = 2.097x - 0.552 = (2.097×-3.5) - 0.552 = - 7.8915

(note that x=-3.5)

Margin of Error is the width of the confidence interval about the mean.

It is given mathematically as,

Margin of Error = (Critical value) × (standard Error of the mean)

Critical value for 95% confidence interval = 1.960

Standard Error of the mean = 0.976

95% Confidence Interval = (Mean) ± [(Critical value) × (standard Error of the mean)]

CI = -7.8915 ± (1.960 × 0.976)

CI = -7.8915 ± 1.91296

95% CI = (-9.80446, -5.97854)

95% Confidence interval for y

= (-9.804, -5.979)

Hope this Helps!!!
