Probability is
(desired outcomes)/(total possible outcomes)
total possible is 8 since 8 total spaces

A. number les than 4, there are 3 numbers (1,2,3) so
3/8 os probability

B. number greater than 4, ther are 4 (5,6,7,8), so 4/8=1/2 is probability

C. multiplule of 3, there are 2 (3,6) so 2/8=1/4 is probability

D. even number, there are 4 (2,4,6,8) so 4/8=1/2 is probability


A. 3/8
B. 1/2
C. 1/4
D. 1/2

Which function has the greater rate of change?
asambeis [7]

Answer:

Function 1

Step-by-step explanation:

The rate of change is measured by the slope m

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = \frac{5}{6} x + 10 ← is in slope- intercept form

with slope m = \frac{5}{6}

Calculate the slope of Function 2 using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (- 1, 14.25) and (x₂, y₂ ) = (1, 15.75) ← 2 ordered pairs from the table

m = \frac{15.75-14.25}{1+1} = \frac{1.5}{2} = 0.75 = \frac{3}{4}

To compare the 2 fractions we require them to have a common denominator.

\frac{5}{6} = \frac{10}{12} and \frac{3}{4} = \frac{9}{12}

\frac{10}{12} > \frac{9}{12}

Thus Function 1 has the greater rate of change

A bag contains Red, Green and Yellow balls. A ball is taken at random from the bag. The probability that it is Red is 0.35 and t
Eddi Din [679]

Answer:

  • P(Yellow)=0.25
  • P(Not Red)=0.65

Step-by-step explanation:

P(Red)=0.35

P(Green)=0.4

(a)Since there are three colours inside the bag

P(Red)+P(Green)+P(Yellow)=1

0.35+0.4+P(Yellow)=1

P(Yellow)=1-(0.35+0.4)

P(Yellow)=0.25

(b) In probability, the sum of an event and its complement is 1.

Therefore:

P(Red)+P(Not Red)=1

0.35+P(Not Red)=1

P(Not Red)=1-0.35

P(Not Red)=0.65
