It should be noted that the sample mean of the difference in temperature will be -0.34.
How to illustrate the information?From the information given, it should be noted that the difference in the temperatures given are -0.5, -0.6, -0.3, 0.1, -0.4.
It should be noted that d is the sample mean while s is the standard deviation.
Therefore, the sample mean of the difference in temperature will be:
= (-0.5 - 0.6 - 0.3 + 0.1 - 0.4)/5
= -1.7/5
= -0.34
The standard deviation of the difference in temperature will be 0.073.

How much principal must be

at an interest rate of 8%?
Answer:
Simple interest: $70.56
Annually compounded Interest: $90.65
Explanation:
A store clerk is paid $10.75/ hour and a store assistant manager is paid $16.25/ hour. How long would it take the store managerto make $500 or more than the store clerk? Round to the nearest hour. Show all work.
It will take approximately 91 hours for the store manager to make $500 or more than the store clerk.
If the store clerk is paid $10.75/ hour and the store assistant manager is paid $16.25/ hour, the difference in their pay per hour will be expressed as:
The difference in the amount earned per hour = 16.25 - 10.75
The difference in the amount earned per hour = $5.5
This means that the store assistant manager will collect $5.5 more than the store clerk in one hour. This can be expressed as:
$5.5 = 1 hour
To determine how long it will take the store manager to make $500 or more than the store clerk, we can write:
$500 = x
Divide both expressions:
[tex]\dfrac{5.5}{500} =\dfrac{1}{x} \\Cross \ multiply\\5.5x = 500 \times 1\\5.5x = 500\\x=\frac{500}{5.5}\\x= 90.9 \ hours[/tex]
This means that it will take approximately 91 hours for the store manager to make $500 or more than the store clerk.

2x = 10
x = 5 Number of cows
21 - 5 = 16 ducks.

I need help with 2 questions, I don't understand how to do them. Any help would be greatly appreciated!
The length of CE is 3.6 and the radius of the circle is 2
The length of CEStart by calculating the length of AD using:
AD^2 = AC^2 - CD^2
This gives
AD^2 = 10^2 - 6^2
AD^2 = 64
Take the square roots
AD = 8
Represent CE with x.
So:
AE = 10 - x
Calculate ED using:
ED^2 = CD^2 - CE^2
ED^2 = AD^2 - AE^2
So, we have:
AD^2 - AE^2 = CD^2 - CE^2
This gives
8^2 - (10 - x)^2 = 6^2 - x^2
Expand
64 - 100 + 20x - x^2 = 36 - x^2
Add x^2 to both sides
64 - 100 + 20x = 36
Evaluate the like terms
20x = 72
Divide by 20
x = 3.6
Hence, the length of CE is 3.6
The radius of the circleThe equation is given as:
x^2 + y^2 + 6x + 5y = -45/4
Rewrite as:
x^2 + 6x + y^2 + 5y = -45/4
Take the coefficients of x and y
Divide them by 2, square the result and add the result to both sides.
So, we have:
x^2 + 6x + (6/2)^2 + y^2 + 5y + (5/2)^2= -45/4+ (6/2)^2 + (5/2)^2
This gives
x^2 + 6x + (6/2)^2 + y^2 + 5y + (5/2)^2= 4
Express as perfect squares
(x + 3)^2 + (y + 5/2)^2 = 4
The circle equation is represented as:
(x - a)^2 + (y - b)^2 = r^2
Where r represents the radius
By comparison, we have:
r^2 = 4
This gives
r = 2
Hence, the radius of the circle is 2

The probability that he comes from a rural area is to be calculated as
100-(50+30)=100-80=20%. So, the probability that he comes from a rural area. So, the probability is 20%.
What is probability?Probability deals with the likelihood of an event or phenomena occurring and is quantified as a number between 0 and 1 inclusive, where 0 indicates an impossible chance of occurrence and 1 denotes the certain outcome of an event. Joint probability refers to a statistical measure that determines the probability of two events occurring together and at the same point in time.
Joint probability is the probability of event Y occurring at the same time that event X occurs. Hence, joint probability is a measure of two events happening at the same time and can only be applied to situations where more than one observation can occur at the same time. Mathematically, it is given by P (A and B) = P(A) * P(B) As in the given situation, the probability estimated is the probability to two events that iPhone is defective and it is manufactured by company A occurring at the same time, it is a joint probability.
Therefore, Probability deals with the likelihood of an event or phenomena occurring and is quantified as a number between 0 and 1 inclusive.

A police officer claims that the proportion of drivers wearing a seat belt in a certain area is less than 40%.
To test this claim, the officer collects a random sample of 80 drivers and monitors if the driver was wearing a seat belt.
From this sample of 80 drivers, the police offers observes that 34 were wearing seat belts.
Assume the conditions needed to conduct a one sample proportion test are satisfied.
The setup for the null and alternative hypothesis is as follows:
H : p = 0.40; H, :p < 0.40, which is a left-tailed test.
Compute the test statistic and p-value for this Hypothesis test using Excel and round your answers to 3 decimal places.
Answer:
0.456
0.324
Explanation:
The null and alternative hypothesis :
H0 : p = 0.40; HA :p < 0.40
Test statistic :
(Ph - P) / sqrt[(p*(1-p))/n]
Ph = X / n
X = 34 ; n = sample size = 80
Ph = 34 / 80 = 0.425
(0.425 - 0.4) / sqrt[(0.4(0.6)) / 80]
0.025 / sqrt(0.003)
0.025 / 0.0547722
Test statistic = 0.4564359
Test statistic = 0.456
Using the P-value from Zscore calculator :
