A probability close to 1 indicates a chance event is very likely to occur. The probability of such an occurrence is a number. The correct option is option A.
What is probability?The probability of such an occurrence is a number used in science to describe how likely it is that the event will take place. In terms of percentage notation, it really is represented by a value between 0 and 1, or between 0% and 100%.
The odds of two complementing events A and B happening, either A happens or B happens, sum up to 1. outcomes are complimentary, the likelihood of "heads" is equal to the likelihood of "tails," and the likelihood of any one of the two possible outcomes is equal to half. A probability close to 1 indicates a chance event is very likely to occur.
Therefore, a probability close to 1 indicates a chance event is very likely to occur. The correct option is option A.

In a particular game, a spinner with four equally-sized sectors labeled 1, 4, 6, and 8 is spun twice. One turn is considered 2 spins of the spinner.
If the sum of the spins is even, you move forward 6 spaces. Otherwise, you move back 2 spaces.
What is the mathematical expectation for the number of spaces moved in one turn?
3 spaces forward
1 space backward
3 spaces backward
1 space forward
Answer:
P(sum is even) = 1/16 + 9/16 = 10/16
= 5/8
P(sum is odd) = 3/8
E(x) = (5/8)(6) + (3/8)(-2) = 3
The mathematical expectation for the number of spaces moved in one turn is 3 spaces forward.

It is linear to Angle A P D.

Vertical angles are the angles opposite each other when two lines cross. They are always congruent.
In this problem we have that

see the attached figure to better understand the problem
therefore
It is congruent to Angle A P C
The True statement about <CPB is It is supplementary to angle APC.
The correct option is (B).
What is Supplementary Angle?In mathematics, the definition of supplementary relates to angles that combine to form a straight angle. It indicates that when two angles sum up to 180 degrees, they are said to be supplementary angles. If two angles complement one another
It has an acute angle on one side and an obtuse angle on the other.The two angles are both right angles.The two angles do not have to be adjacent to form a straight line.As, when two angles that when added together equal 180 degrees is Supplementary Angle.
From the figure if we add <CPB and <APC forms the straight line gives the angle 180 degree.
i.e., <CPB + <APC = 180
or, <CPC= 180- <APC
So, <CPB is supplementary to angle APC.

kala is in charge of planning a reception for 3400 people. she is trying to decide which snacks to buy. she has asked a random sample of people who are coming to the reception what their favorite snack is. Here are the results Brownies for 54 people, pretzels for 56 people potato chips for 52 people other for 63 people. based on the above sample predict the number of the people at the reception whose favorite snack will be brownies. round your answer to the nearest whole number. do not round any intermediate calculations
Answer:
816
Step-by-step explanation:
Find total number of people asked by adding all the people.
54 + 56 + 52 + 63 = 225
So, 54 out of 225 people have their favorite snack as brownies.
We need to find out how many it is for 3,400. We can do that by cross multiplying.
54 = x (did it like this so it's better visually)
225 3400
Multiply both sides by 3,400 and divide to get:
x = 816
$6000 is invested in an account that earns 4.5% annual interest, compounded continuously. What is the value of the account after 8 years.
Answer:
Convert 4.5% to a decimal. 6000,0.045, 8 years
Step-by-step explanation:
I used math--way
The value of the account after 8 years with continuous compounding is approximately $8593.76.
To find the value of the account after 8 years with continuous compounding, we can use the formula for continuous compounding:
A=P⋅e rt
Where:
A is the amount of money accumulated after
t years, including interest.
P is the principal amount (the initial amount of money).
r is the annual interest rate (in decimal).
t is the time the money is invested for, in years.
e is the base of the natural logarithm, approximately equal to 2.71828.
Given:
P=$6000
r=4.5%=0.045 (in decimal)
t=8 years
Substituting the values into the formula:
A=6000⋅e 0.045⋅8
Now, let's calculate this:
A=6000⋅e 0.36
A≈6000⋅2.71828 0.36
A≈6000⋅1.432292989
A≈8593.757934
Rounding to two decimal places, the value of the account after 8 years with continuous compounding is approximately $8593.76, which is slightly different from the provided answer of $8532.60. This discrepancy might be due to rounding differences or calculation variations.

which estimator will consistently have a skewed sampling distribution?
A.) coefficient of variation
B.) median
C.) standard deviation
D.) variance
Answer:
other duds wrong its d variance
Step-by-step explanation:
im 100% sure
The correct answer is option (C) Standard Deviation.The estimator that consistently has a skewed sampling distribution is the standard deviation, especially when the original data is non-symmetric or skewed.
Among the given options, the estimator that will consistently have a skewed sampling distribution is the standard deviation. When estimating the standard deviation from a sample, the resulting distribution does not always follow a normal pattern, especially if the original data is skewed. The standard deviation is calculated using each data point's deviation from the mean, which can lead to skewed results in non-symmetric distributions.
For instance, in a skewed distribution with extreme values, the mean and subsequently the standard deviation can be disproportionately influenced by those extremities, hence failing to accurately reflect the spread of the majority of the data. Therefore, sometimes measures like the median, which is not as sensitive to outliers, are considered better representations of the central tendency in a skewed data set.
Additionally, the standard deviation is meaningful for symmetrical distributions, while skewed distributions require a consideration of other measures such as the modes, medians, or quartiles. When presented with data, always visualize it using a histogram or a box plot to better understand the distribution.
