Deborah finds that that the theoretical probability of flipping "heads" on a fair coin was 50%. After she flipped the fair coin 100 times, she calculated that she flipped heads 45 times. what is the percent difference in theoretical and experimental probability
Answer: 5% if it’s bubble sheet then 0.05
Step-by-step explanation:
Probability of flipping heads=50%
Probability of flipping practically = 45/100
=45
So 50%-45% = 5%
Consider the following time series. t 1 2 3 4 5 yt 6 10 8 13 15
(a) Choose the correct time series plot. (i) (ii) (iii) (iv) What type of pattern exists in the data?
(b) Use simple linear regression analysis to find the parameters for the line that minimizes MSE for this time series. If required, round your answers to two decimal places. y-intercept, b0 = 4.1 Slope, b1 = 2.1 MSE = ????
(c) What is the forecast for t = 6? If required, round your answer to one decimal place. 16.7 I know how to do it all but the MSE.
Answer:
Kindly check explanation
Step-by-step explanation:
Given the data :
t __1 2 3 4 5
yt_ 6 10 8 13 15
Using technology to produce a linear model :
The linear model obtained shows a positive linear pattern exist for the time series data :
The parameters for the line that minimizes MSE for the then series is :
y = 2.1t + 4.1
Where, slope = 2.1 ; intercept = 4.1
The mean squared error :
Sum of squared estimate of error = 9.1
Mean squared error = √9.1
Mean squared error = 3.02
Forecast for t = 6
y = 2.1t + 4.1
y = 2.1*6 + 4.1
y = 12.6 + 4.1
y = 16.7
Gregorio made 25 quart of hot chocolate. Each mug holds 1/10 quart. How many
mugs are used for the hot chocolate?
Answer:
4 mugs of hot chocolate
Step-by-step explanation:
So, we must find out how many mugs of hot chocolate we can make.
Then we set up a ratio of amount of chocolate to mugs such as
(2/5) / (1/10) = (2/5)(10/1) = 20/5 = 4 mugs of hot chocolate
Hope this answer helps you :)

Given:
The y-intercept of a line = 6
The slope of the line = [tex]-\dfrac{3}{2}[/tex]
To find:
The graph of the given line.
Solution:
The slope intercept form of a line is:
[tex]y=mx+b[/tex]
Where, m is the slope and b is the y-intercept.
Putting [tex]m=-\dfrac{3}{2}[/tex] and [tex]b=6[/tex] in the above equation, we get

Step-by-step explanation:
As a general rule, words like "all", "every", "the", etc. are represented with ∀.
However, some sentences may be need to rephrased before such sentence can be rephrased
So, the following replacement will be made:

(b)
[tex]Every \to[/tex] ∀
[tex]real\ number \to x[/tex]
(c)
First, we need to rephrase this sentence to:
Every irrational number is not integer
So, the replacement is:
[tex]Every \to[/tex] ∀
[tex]irrational\ number \to x[/tex]
(d)
First, we need to rephrase this sentence to:
Every logician is lazy
So, the replacement is:
[tex]Every \to[/tex] ∀
[tex]lazy \to x[/tex]
(e)
First, we need to rephrase this sentence to:
The integer 2,147,581,953...............
So, the replacement is:

Soosie's Cookie Company had fixed costs of $1250 and variable costs of $4.25 per dozen gourmet cookies that were baked and packaged for sale. Write an equation that can be used to determine the total cost when x dozens of cookies are baked and sold. Then determine the total cost of baking and selling 85 dozen gourmet cookies.
Answer:
$1250.00 + (x)$4.25 =
Step-by-step explanation
So fixed costs are $1,250.00.....every dozen you bake add $4.25 to the costs, cook one dozen you have $1,250.00 plus $4.25 or a total of $1,254.25.
Cook 10 dozen and you add $45.25 = the $1,250.00 for a new total of $1,295.25.

A stack of squares has 170 squares in the bottom row, 156 in the second row from the bottom, 142 in the third row from the bottom and 128 in the fourth row from the bottom. How many squares will there be in the 11th row from the bottom ? - a table always makes these sums easier!)
9514 1404 393
Answer:
30
Step-by-step explanation:
The sequence of square counts is ...
170, 156, 142, 128
The differences from one row to the next are ...
-14, -14, -14
We see that the differences are constant, so we know the sequence is an arithmetic sequence with first term 170 and common difference -14. This means the n-th term is ...
an = a1 +d(n -1) . . . . . . for first term a1 and common difference d
an = 170 -14(n -1)
For n=11, the number of squares is ...
a11 = 170 -14(11 -1) = 30
There will be 30 squares in the 11th row.
How many 1/3 servings are in 36 servings?
Answer:
108
Step-by-step explanation: When you want to find out how much a fraction fits into a number, you have to multiply it by how much it takes to make 1 whole number using the fraction. 1/3 requires 3 of them to make 1 whole number. This means that 36 can be multiplied by 3, which gives us the answer of 108
Answer:
108 of 1/3 servings are in 36 servings.
Step-by-step explanation:
3/1 multiples 3 become 1.
1 multiple 36 and equal 36,
so,3 multiple 36.
3×36=108

For 90% confidence interval for a sample of 36 people with a mean of 64 and standard deviation of 4 the answer is C. 64 +1.645. 4. V36.
What is confidence interval?A confidence interval is a range of values that is likely to contain the true population parameter with a certain level of confidence.
In statistics, it is commonly used to estimate the population mean based on a sample mean, standard deviation, and sample size.
The confidence level represents the probability that the true population parameter falls within the calculated interval.
The correct expression to find the 90% confidence interval for a sample of 36 people with a mean of 64 and standard deviation of 4 is:
64 ± 1.645(4/√36)
Simplifying the expression:
64 ± 1.645(4/6)
64 ± 1.645(0.6667)
64 ± 1.0967
The 90% confidence interval is (62.9033, 65.0967).
Therefore, the answer is C. 64 +1.645. 4. V36.

Answer:
sin(x)−1/3(sin3(x))+C
Step-by-step explanation:
use u substitution method to integrate
cos³(x) = cos(x) cos²(x)
… = cos(x) (1 - sin²(x))
Substitute u = sin(x) and du = cos(x) dx. Then in the integral, you get
∫ cos³(x) dx = ∫ (1 - u ²) du
… = u - 1/3 u ³ + C
… = sin(x) - 1/3 sin³(x) + C
