My watch loses three minutes every hour today at 6:00am it was marking the exact time what time will it actually be when my watch says 6:00pm
Your watch will be 39 minutes behind the actual time when it says 6:00 PM. Therefore, the actual time will be 5:21 PM.
If your watch loses 3 minutes every hour, then from 6:00 AM to 6:00 PM, it will lose a total of 13 hours * 3 minutes/hour = 39 minutes.
So, when your watch says 6:00 PM, the actual time will be 6:00 PM - 39 minutes = 5:21 PM.
Here is a more detailed explanation of the calculation:
* Hour 1: 6:00 AM - 6:03 PM = 3 minutes lost
* Hour 2: 7:00 AM - 7:03 PM = 3 minutes lost
* Hour 3: 8:00 AM - 8:03 PM = 3 minutes lost
* ...
* Hour 13: 5:00 PM - 5:03 PM = 3 minutes lost
* Hour 14: 6:00 PM - 5:21 PM = 39 minutes lost
Therefore, the time elapsed and actual time will be 5:21 PM.

I believe its A, correct me if i'm wrong.
Step-by-step explanation:
A hypothesis test involves a comparison between research results from a sample and a hypothesis about a population.
Thus, option (A) is correct.
In hypothesis testing, a researcher starts with a null hypothesis, which represents the assumption of no difference or no effect in the population.
The researcher collects data from a sample and performs statistical analysis to determine whether the evidence supports or rejects the null hypothesis in favor of an alternative hypothesis.
The research results obtained from the sample are compared to the hypothesis about the population to determine whether there is enough evidence to reject the null hypothesis and accept the alternative hypothesis.
Thus, option (A) is correct

Hugo is serving fruit sorbet at his party. he has 1 gallon of fruit sorbet to serve to 32 friends. if each person receives the same amount, how many cups of fruit sorbet will each person get? 14 cup 12 cup 34 cup 1 cup
If each person receives the same amount, each person at Hugo's party will get 0.5 cups, or 1/2 cup, of fruit sorbet.
To determine how many cups of fruit sorbet each person will get, we need to convert the volume of the sorbet from gallons to cups, and then divide by the number of people who will be served.
Since 1 gallon is equal to 16 cups, we can multiply the number of gallons by 16 to get the total number of cups of sorbet. In this case, 1 gallon x 16 cups/gallon = 16 cups of fruit sorbet.
To find out how many cups of sorbet each person will get, we simply divide the total number of cups by the number of people. In this case, 16 cups ÷ 32 people = 0.5 cups/person.

Students at Garcia Middle School took a survey about their favorite school.The results showed that 182 students rated pizza as their favorite food. This number represented 68% of the number of students who took the survey.What was the total number of students that took the survey?
Answer:
267.64 students
Step-by-step explanation:
Let the total number of students that took the survey be represented as x
This number represented 68% of the number of students who took the survey.
The results showed that 182 students rated pizza as their favorite food.
Therefore:
68% × x = 182 Students
68/100 × x = 182
68x/100 = 182
Cross Multiply
68x = 182 × 100
x = 182 × 100/68
x= 267.64705882 students
Therefore, the total number of students that took the survey is Approximately 267. 64 students
Mr. koger is making copies of the school literary magazine to distribute to students and faculty. he has access to two copy machines: an older machine and a new machine. if he used only the older machine, it would take 80 minutes longer than if he used only the new machine. if he used both machines, he would finish the job in 30 minutes. when m is the number of minutes it would take to finish the job using only the new machine, the situation is modeled by this rational equation: . how many minutes would it take to finish the job if mr. koger used only the new machine? a. 20 minutes b. 40 minutes c. 50 minutes d. 60 minutes
Using the rational equation it would take 40 minutes to finish the job if Mr. Koger used only the new machine.
So, option B: 40 minutes is the correct option.
What are rational equations?Equations with variables in the denominators of rational expressions are referred to as rational equations.
The given rational equation to model the situation is -
1/m+1/(m+80)=1/30
On simplifying -
30m+30(m+80)=m(m + 80)
30m+30m+240=m^2+80m
-20m+240=m^2
-m^2-20m+240=0
On factorizing the equation -
-m^2-60m+40m+240=0
-m(m+60)+40(m+60)=0
(-m+40)(m+60)
-m=-40, m=-60
m=40, m=-60
Since, time cannot be negative so the value m=40 is the correct value.
Therefore, the time taken by new machine is 40 minutes.

A data visualization tool that updates in real time and gives multiple outputs is called a data dashboard. What is a scatter plot? A scatter plot is a type of diagram used to display two variables on a two-dimensional plot. The positioning of data points on a scatter plot graphically depicts the correlation between the two variables. To construct a scatter plot, two variables (independent and dependent variables) are plotted on a graph.
The independent variable is plotted on the horizontal (x) axis and the dependent variable is plotted on the vertical (y) axis. A point is plotted for each pair of values, and the pattern of the points suggests a relationship between the two variables.A scatter plot is useful in displaying the correlation between two variables. The correlation is positive if the points are in an upward direction. The correlation is negative if the points are in a downward direction. A lack of correlation, or random points, is suggested by a scatter plot with no apparent pattern.

the 98.4% confidence interval for snapdragons grown in compost is (20.91, 38.43). what is the margin of error of this confidence interval?
The margin of error of the 98.4% confidence interval for snapdragons is 3.71.
The midpoint of the range is calculated by adding the upper and lower bounds and then dividing by two. So, the sample mean is `(20.91 + 38.43) / 2 = 29.67`.
The margin of error is calculated by multiplying the critical value of z* (1.96 for a 98.4% confidence level) by the standard error of the mean. The formula for calculating the margin of error is:
`Margin of error z*(standard deviation/√n`).
The formula is `range/4 = 1.96 * standard deviation/√n`.Now, solve for the standard deviation:
`standard deviation = (range/4) * √n / 1.96`
Substituting the values: `(38.43 - 20.91)/4 = 1.96 * standard deviation/√n`
Simplifying the equation: `4.26 = (1.96*standard deviation)/√n`
Squaring both sides: `4.26^2 = 3.8416 = (1.96^2 * standard deviation^2)/n`
Substituting the value of the standard deviation: `3.8416 = (1.96^2 * ((38.43 - 20.91)/4)^2) / n`
Solving for n: `n = ((1.96^2 * ((38.43 - 20.91)/4)^2) / 3.8416) = 31.54`
Now that we know the sample size, we can calculate the standard error of the mean:
`standard error = standard deviation/√n = ((38.43 - 20.91)/4)/√31.54 = 1.89`.
The margin of error is `1.96 * 1.89 = 3.71`.
The 98.4% confidence interval for snapdragons grown in compost is (20.91, 38.43). The margin of error of this confidence interval is 3.71.
