Answer:

A. Simon's unit rate is 2 more miles per hour than Eric's unit rate

Step-by-step explanation:

We are concerned with the number of miles each runs in 1 hour.

For Eric, that means x=1 in his equation, so his mileage is ...

y = 6×1 = 6 . . . . miles

For Simon, it means we want to find time = 1 hour on the horizontal axis at the bottom of the graph. Then we want to see where the graphed line crosses that vertical line. The point of crossing has horizontal line that goes over to 8 on the vertical distance axis. That is, Simon runs 8 miles in 1 hour.

Eric's unit rate (miles in 1 hour) is 6 miles per hour.

Simon's unit rate (miles in 1 hour) is 8 miles per hour.

Simon's unit rate is 2 more miles per hour than Eric's unit rate.

F(x) = -2x + 9, find x if f(x) = 23

JulijaS [17]

Answer:

x = -7

Step-by-step explanation:

f(x) = -2x + 9

f(x) = 23

therefore, f(x) =

-2x + 9 = 23

-2x = 23 - 9

-2x = 14

-x = 14 ÷ 2

-x = 7

x = -7

The lifespan of a lion in a particular zoo are normally distributed. The average lion lives 12.5 years the. Standard deviation i

Anika [276]

Answer:

0.1585

Step-by-step explanation:

Solution:-

The lifespan of a lion in a particular zoo is normally distributed with average lion lives:

Mean u = 12.5 years

Standard deviation s = 2.4 years

We are to use the empirical rule ( 68-95-99.7% ) to estimate the probability of a lion living between 5.3 and 10.1.

- The empirical rule ( 68-95-99.7% ) states:

P ( u - s < X < u + s ) = 68%

P ( u - 2s < X < u + 2s ) = 95%

P ( u - 3s < X < u + 3s ) = 99.7%

- The test have the following number of standard deviations (s):

u - s < X < u + s = 12.5 - 2.4 < X < 12.5 + 2.4 = 10.1 < X < 14.9

u - 2s < X < u + 2s = 12.5 - 4.8 < X < 12.5 + 4.8 = 7.7 < X < 17.3

u - 3s < X < u + 3s = 12.5 - 7.2 < X < 12.5 + 7.2 = 5.3 < X < 19.7

Hence,

P ( 10.1 < X < 14.9 ) = 0.68

P ( 7.7 < X < 17.3 ) = 0.95

P ( 5.3 < X < 19.7 ) = 0.997

- We need P ( X < 10.1 ) and P ( X < 5.3 ):

P ( X < 10.1 ) = [ 1 - P ( 10.1 < X < 14.9 ) ] / 2

= [ 1 - 0.68 ] / 2

= 0.16

P ( X < 5.3 ) = [ 1 - P ( 5.3 < X < 19.7 ) ] / 2

= [ 1 - 0.997 ] / 2

= 0.0015

Hence,

P ( 5.3 < X < 10.1 ) = P ( X < 10.1 ) - P ( X < 5.3 )

= 0.16 - 0.0015

= 0.1585

What are the relationships among radii, chords, tangents, and inscribed and circumscribed angles?

Mars2501 [29]

These are all parts of circles.

A radius is the distance from the center of a circle to the edge.

A chord is a line segment from 2 different places on a circle.

A tangent is a line that touches the edge of a circle in only 1 place.

Inscribed angles are inside a circle and circumscribed angles are on the outside of a circle.

Consider the equation y=16-x. which of the following statements is true

musickatia [10]

Answer:

C. Both x is a function of y and y is a function of x

Step-by-step explanation:

A <u>function</u> is a relationship which assigns to each input (from the domain) value, a unique output (from the range).

y is a function of x means x is from domain, y is from range

x is a function of y means y is from domain, x is from range

1. Given $y=16-x$
