A spinner has 10 10 ​equal-sized sections. Six Six of the sections are purple purple. a. What is the probability that the spinne
borishaifa [10]

Answer:

P(Spinner lands on purple section) = 0.6 = 60%

Step-by-step explanation:

We are given the following in the question:

Number of sections = 10

Number of purple sections = 6

\text{Probability} = \displaystyle\frac{\text{Number of favourable outcomes}}{\text{Total number of outcomes}}

a) probability that the spinner will land on purple purple

P(purple) =

=\dfrac{6}{10} = 0.6

0.6 is the probability that the spinner will land on purple purple.

b) Interpretation of probability

0.6\times 100\% = 60\%

There is a 60% chance that the spinner will land on purple color.

Find it nearest tenths
NNADVOKAT [17]

Answer:

Step-by-step explanation:

finding PR  ( public relations  :D , not that PR  , the PR on this triangle thingy )

use law of cosines, again

c=sq rt [ a^2+b^2﹣2*a*b*cos(C) ]

where

c=PR

a= 9

b = 22

C = the angle of Q or    180 =   97+24+Q  so Q = 180-97-24 = 59°

they tried to trick us.. by not giving us the angle C  for the above cosine formula , but we figured out their diabolical plan  :D   yay super hero math

then

PR = sq rt [ 9^2 + 22^2 - 2*9*22*cos(59) ]

PR = sq rt [ 81 + 484 -203.9550777 ]

( notice that now it is a subtraction sign instead of a plus sign, this time? )

PR = sq rt [361.0449 ]

PR = 19.0011

to the nearest 10th

19.0 :)
