Reese will choose one headband, one

Mathematics
1 answer:
IRINA_888 [86]3 years ago
5 0

Answer:

\dfrac{1}{18}

Step-by-step explanation:

Number of Headband Types=3

P(Reese will  choose a blue headband)=1/3

Number of Types of Necklace=2

P(Reese will  choose a  silver  necklace)=1/2

Number of Types of Earrings=3

P(Reese will  choose a  silver earrings)=1/3

In Probability Theory,

P(A AND B)=P(A) X P(B)

Therefore, the probability that Reese will  choose a blue headband, a silver  necklace, and a silver pair of earrings

=\dfrac{1}{3}X \dfrac{1}{2}X\dfrac{1}{3}\\\\=\dfrac{1}{18}

Licemer1 [7]

Answer:

It would be 9.6 inches after 4 weeks.

The expression you would use is  5 + 2.5 × ww = ?

Step-by-step explanation:

At the beginning of spring, Eva planted a small sunflower in her backyard. When it was first planted, the sunflower was 5 inches tall. The sunflower then began to grow at a rate of 2.5 inches per week. How tall would the sunflower be after 4 weeks? How tall would the sunflower be after ww weeks? Write an expression.

So the sunflower was 5 inches tall to start off.

First you need to do 2.5 times 4.

Which is 9.6 inches after 4 weeks.

The expression you would use is.

5 + 2.5 × ww = ?

AlexFokin [52]

Complete Question

The complete question is shown on the first uploaded image  

Answer:

The probability is  P(4 \ doors | sunroof ) =  0.40

Step-by-step explanation:

 From the question we are told that

        The number of cars packed is  n = 100

The objective of this solution is to find the probability that the car which has a sunroof also has four doors

   This probability is mathematically represented as

               P(4 \ doors | sunroof )

Baye's Rule define this probability mathematically  as

             P(4 \ doors | sunroof ) =  \frac{P(4 \ doors \ n \ sunroof )}{P(sunroof)}

   From the diagram

          P(4 \ doors \ n \ sunroof ) =  20

and     P(sunroof) =  50

So

      P(4 \ doors | sunroof ) =  \frac{20}{50}

      P(4 \ doors | sunroof ) =  0.40

Where can u place these at tell me
Alex777 [14]
The best thing to do is to rewrite the fractions as decimals
-2/3 is approx. equal to -0.6666667
So a little past half way (to the left) between -1 and 0
1 1/5 is 1.5 so that is right between 1 and 2

Hope this helps :)
