A jar contains 8 red marbles, 10 blue marbles, and 2 yellow marbles. One marble is chosen at random. The color is recorded in the table and then it is returned to the jar. This is repeated 40 times. What is the experimental probability of choosing a yellow marble? Express your answer as a percent to the nearest whole number.
RED/14 BLUE/16 YELLOW/10
Answer:
1/4 or 25%Step-by-step explanation:
Experimental probability:
Pe = number of event occurred / number of attemptsProbability of yellow:

Find the area of the figure shown below and chose the appropriate result
Answer:
it's the first option or A
Step-by-step explanation:
well 9 * 10 is 90 which leaves you with the numbers 14 and 3 we used 10 so that gives us 4 and 3 multiply those and you get 12 so add 12 to 90 and you get 102 thus the answer is A

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?

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

Answer:
£140
Step-by-step explanation:
First count up the amount of full squares, then you see the partially filled squares and try find the match for it to fill the square. It ends up being 24 squares, meaning 24 square feet. That multiplied by £5, as that is the cost of red wood, gives you the answer of £140

Step-by-step explanation:
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

Answer:
XY = 11.25
Step-by-step explanation:
Corresponding sides are proportional, so ...
XY/AB = XZ/AC
XY = (AB)(XZ/AC) = 5(18/8)
XY = 11.25
A paint manufacturer wants to determine the average drying time of a new interior wall paint. For n = 50 test areas of equal size he obtained a sample mean drying time of ¯x = 63.3 minutes and a sample standard deviation of s = 8.4 minutes. (a) (5 points) Construct the 95% confidence interval for the true mean µ. (b) (5 points) Suppose the population has a normal distribution, construct the exactly 95% confidence interval for the true mean µ. (c) (5 points) Suppose the population has a normal distribution, construct the 95% prediction interval for a new observation.
Answer:
a) the 95% confidence interval for the true mean µ is 60.971, 65.629
The exact 95% confidence interval for the true mean µ is 60.971, 65.629
P (x`- ∝ s/√n<u <x`+ ∝ s/√n) = 0.95
Step-by-step explanation:
n= 50
x`= 63.3
s= 8.4 minutes
∝= 95%= ±1.96
The formula for calculating the confidence interval is:
x`± ∝ s/√n
Putting the values
x`± 1.96 s/√n
63.3 ± 1.96(8.4/√50)
63.3± 2.3287
60.971, 65.629
a) the 95% confidence interval for the true mean µ is 60.971, 65.629
b) Putting the values
x`± 1.96 s/√n
63.3 ± 1.96(8.4/√50)
63.3± 2.3287
The exact 95% confidence interval for the true mean µ is 60.971, 65.629
c) The prediction level tells that the drying time of the wall from 60.971 to 65.629 minutes must be in the range 95 % of the time.
And is given by
P (x`- ∝ s/√n<u <x`+ ∝ s/√n) = 0.95
What is equivalent to 0 = 2x2 - 16x – 18 when completing the
square?
Answer:
x = 1
x = -9
Step-by-step explanation:
(2x2 + 16x) - 18 = 0
2x2 + 16x - 18 = 2 • (x2 + 8x - 9)
x2 + 8x - 9
-9 + 1 = -8
-3 + 3 = 0
-1 + 9 = 8
2 • (x + 9) • (x - 1) = 0
2 = 0
x+9 = 0
x = -9
x-1 = 0
x = 1
x2 + 8x - 9 = 0
x2+8x = 9
(x+4) • (x+4) =
(x+4)2
x2+8x+16 = 25 and
x2+8x+16 = (x+4)2
(x+4)2 = 25
x = -4 + √ 25
x2 + 8x - 9 = 0
has two solutions:
x = -4 + √ 25
or
x = -4 - √ 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.

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
