Answer:
25%
Step-by-step explanation:
right on the test
The required probability of the coin landed on heads and the die landed on an even number is 25%.
Given,
Meghan flipped a quarter and rolled a standard six-sided die. The probability that the coin landed on heads and the die landed on an even number is to be determined.
Probability can be defined as the ratio of favorable outcomes to the total number of events.
Sample space of coin = { head, tail } = 2
Sample space for die = { 1, 2, 3, 4, 5, 6 } = 6
favorable outcome for coin = head = 1
favorable outcome for the die to landed on even number = {2, 4, 6} = 3
Now the probability that the coin landed on heads and the die landed on an even number is,
P = probability of head-on coin * probability of the even number on die
P = 1/2*3/6
P = 1/4
P = 0.25 and 25%
Thus, the required probability of the coin landed on heads and the die landed on an even number is 25%.

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)
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.

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?
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

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? *
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

Pleaseeee I needddd helpppp!!!!!!
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

A baseball team has scheduled its opening game for April 1. If it rains on April 1, the game is postponed and will be played on the next day that it does not rain. 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.
Required:
What is the standard deviation of the amount the insurance company will have to pay?

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?
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
