Iteru [2.4K]3 years ago

Answer:

0.624

Step-by-step explanation:

Number who have run a red light = 315

Number who haven't run a red light = 190

From the data :

The total number of people sampled = total possible outcome = (315 + 190) = 505

Selecting a person at random, probability that the selected person has run a red light :

P = required outcome / Total possible outcomes

Required outcome = Number who have run a red light = 315

P(having run a red light) = 315 / 505 = 0.624

Write the formula for the volume of a square prism, V = s-h, in terms of h. Then find the height h of a square prism with volume
vodomira [7]

Answer:

h = \frac{3V}{s^2}

height (h) = 5 cm

Step-by-step explanation:

Volume of prism in terms of h (height):

V = \frac{1}{3}s^2h

V = \frac{s^2h}{3}

Multiply both sides by 3

V*3 = \frac{s^2h}{3}*3

3V = s^2h

Divide both sides by s^2

\frac{3V}{s^2} = \frac{s^2h}{s^2}

\frac{3V}{s^2} = h

h = \frac{3V}{s^2}

Find height (h) given V = 60 cm³ and side length (s) = 6 cm. Plug the values into the formula above:

h = \frac{3(60)}{6^2}

h = \frac{180}{36}

h = 5

Height = 5 cm

These three points are collinear. (3, 6), (-2, -9), (0, -4)<br> True False
mr_godi [17]

Answer:

False

Step-by-step explanation:

to determine if the points are collinear, determine the rate of change(slope) between (-2, -9) and (0, -4) and then the rate of change between (0, -4) and (3,6) and rate of change between (-2, -9) and (3, 6). if the rates are equivalent then the points are all collinear

between (-2, -9) and (0, -4):

m=(y2-y1)/(x2-x1)

  =(-4-(-9))/(0-(-2))

  =5/2

between (0, -4) and (3,6):

m=(y2-y1)/(x2-x1)

  =(6-(-4))/(3-0)

=10/3

because 5/2 does not equal 10/3 the rates of change are not equal and the points are not collinear, do not need to consider slope between (-2, -9) and (3, 6)
