Charleston's mom has a basket of nail polish containing 7 bottles of
pink, 2 purple, 1 red, 1 black, 1 white, and 3 glitter. If Charleston reaches
into the basket and pulls out a random bottle of nail polish, what is the
probability it will not be pink or purple? *

Answers

Answer:

Step-by-step explanation:

total number of nail polish = 15

number of pink nail polish= 7

number of purple nail polish = 2

so 7+2 = 9

15-9 = 6

so probability( of not getting pink or purple nail polish ) = favourable outcomes/ total outcomes

= 6/15

A coach is assessing the correlation between the number of hours spent practicing and the average number of points scored in a game. The table shows the data:


Number of hours spent practicing
(x) 0 0.5 1 1.5 2 2.5 3 3.5 4
Score in the game
(y) 5 8 11 14 17 20 23 26 29


Part A: Is there any correlation between the number of hours spent practicing and the score in the game? Justify your answer. (4 points)

Part B: Write a function that best fits the data. (3 points)

Part C: What does the slope and y-intercept of the plot indicate? (3 points)

Answers

Answer:

Part A:

Is there any correlation between the number of hours spent practicing and the score in the game? Justify your answer.

Yes, there appears to be a positive correlation between the number of hours spent practicing and the score in the game as seen in the scatter diagram. The pattern formed is a straight line that rises as one moves from 0 along the x axis.

Part B:

Write a function that best fits the data. (3 points)

y = 5 + 6x

Score in the game = 5 + 6*(Number of hours spent practicing)

Part C:

What does the slope and y-intercept of the plot indicate? (3 points)

slope = 6

When the number of hours spent practicing increases by by 1 hour, the score in a game is predicted to increase by an average of 6.

y-intercept = 5

Score in a game is predicted to be 5 when the Number of hours spent practicing is equal to 0.

The team purchases insurance against rain. The policy will pay 1000 for each day, up to 2 days, that the opening game is postponed. The insurance company determines that the number of consecutive days of rain beginning on April 1 is a Poisson random variable with mean 0.6.

A six-sided die is tossed and a coin is flipped. What is the fractional probability that the die lands on 4 and the coin is heads?

Answers

Answer:

1/12

Step-by-step explanation:

First we have to calculate the sample space i.e. The total number of outcomes,

(H represents heads, T represents Tails and Numericals represent the number on the die)

H1, H2, H3, H4, H5, H6, T1, T2, T3, T4, T5, T6

= 12 sample spaces

Ok now so what is the probability that the die lands on 4 and it pops up as heads. So when we see the total outcomes we see that such event has only one such outcome

The number of outcomes/Total number of outcome

So therfore we can represent it in fraction as

1 / 12

An incomplete sentence is given. “The value of 2 x 1014 is times the value of 4 x 106" What number correctly completes the sentence?​

Answers

Answer:

0.00000002

Step-by-step explanation:

Let the unknown number be x.

Translating the word problem into an algebraic expression, we have;

2 * 10¹⁴ * x = 4 * 10⁶

To find the value of x;

x = 4 * 10⁶/2 * 10¹⁴

x = 2 * 10^{-8}

Therefore, the value of 2 x 10¹⁴ is 0.00000002 times the value of 4 x 10⁶

Pleaseeee I needddd helpppp!!!!!!

Answers

Answer:

x = 40

Step-by-step explanation:

Measure of an external angle of a circle = ½(difference of the intercepted arcs)

This means that:

½(PQ - RS) = m<T

m<T = x/2

PQ = (x + 70)°

RS = (x + 30)°

Plug in the values

½((x + 70) - (x + 30)) = x/2

½(x + 70 - x - 30) = x/2

½(x - x + 70 - 30) = x/2

½(0 + 40) = x/2

½(40) = x/2

20 = x/2

Multiply both sides by 2

20*2 = x

40 = x

x = 40
