The Jenkins family and the Moore family each used their sprinklers last summer. The water output rate for the Jenkins family's sprinkler was per hour. The water output rate for the Moore family's sprinkler was per hour. The families used their sprinklers for a combined total of hours, resulting in a total water output of . How long was each sprinkler used?
How long was each sprinkler used is 30 hours.
How long was each sprinkler usedLet x represent how long each sprinkler was used
Hence:
40(x)+15(55-x)=1575
40x+825-15x=1575
Collect like terms
40x+-15x=1575-825
25x=750
Divide both side by 25x
x=750/25
x=30 hours
Therefore the Jenkins used the sprinklers for 30 hours while Green's used it for 25.

A large food distributor claims that 45% of all individuals who purchase eggs from its grocery stores choose standard white eggs, 25% choose standard brown eggs, 20% choose organic eggs, and 10% choose free-range eggs. To investigate this claim, researchers collected data from a random sample of the distributor's customers in a large city. The results were 274 white, 159 brown, 126 organic, and 41 free-range egg purchases. Are the data from the sample consistent with the distributor's claim? Conduct an appropriate statistical test at the 5% significance level to support your conclusion. Make sure to include parameters, check conditions, and show calculations before formulating a conclusion. (10 points)
The conclusion based on the statistics is that 45% of all individuals who purchases eggs from its grocery store choose white eggs
How to illustrate the information?It should be noted that the information given illustrates that the null alternative hypothesis have been illustrated.
The level of significance is 0.05. The test statistic will be 6.92. Therefore, the degree of freedom will be:
= 4 - 1 = 3
Therefore, from the chi square table, the critical value is 7.815. Since the test statistic is less than the critical value, we fail to reject the null hypothesis
Therefore, the conclusion is that 45% of all individuals who purchases m eggs from its grocery store choose white eggs.

A plane crashes on the border of the USA and Canada where do you bury the survivors?
Survivors are not to be buried.
Who are survivors?The survivors of accidents are those that escape death or being killed during the course of the events. They could be totally unhurt or injured in a non-fatal way and get back to their healthy self with time.
Unlike survivors, dead bodies are considered a nuisance to the environment. Hence, they are quickly buried before they start decomposing and become a source of diseases to the populace.
In other words, survivors are not usually buried in any sane society. Only those that are dead are buried.
So, if a plane crashes on the border of the USA and Canada, burying the survivors does not come up at all. That would be a total aberration.
