The individual cited a study of 1200 randomly selected parents that reported that the children of parents who downloaded the app on their phone, on average, had 10 fewer cases of daycare-related illness during the study period than those whose parents did not download the app. Which of the following statements is correct?
a. Because downloading the app seems to decrease child illness, the app should be effective for decreasing child neglect as well.

b. Downloading the app will cause daycare workers to not spread germs.

c. The study was an experiment rather than an observational study.

d. The sample size of the study was too low to determine a result.

e. There seems to be a relationship between the app and preventing the spread of daycare illness.

Answer:

Option E is correct.

There seems to be a relationship between the app and preventing the spread of daycare illness.

Step-by-step explanation:

The study was carried out on a sample size of 1200 randomly selected parents and it was discovered that children of parents who downloaded the app, on average, had 10 fewer cases of daycare-related illness during the study period than those whose parents did not download the app.

Examining the options one at a time

a. Because downloading the app seems to decrease child illness, the app should be effective for decreasing child neglect as well.

The study showed that downloading the app seemed to truly decrease daycare-related illnesses in children, but it does not mention anything about child neglect. Hence, this is not a correct conclusion for the study.

b. Downloading the app will cause daycare workers to not spread germs.

The study did not in any way study how the app works, whether it prevents daycare workers to not spread germs, so, this conclusion seems like jumping the gun. It isn't an accurate conclusion of what the study did.

c. The study was an experiment rather than an observational study.

The study was actually more of an observational study. An observational study involves the researchers taking notes and recording the effects of a particular variable or lack of thereof, without interfering with the study.

d. The sample size of the study was too low to determine a result.

A sample size of about 1200 is a large enough sample for the sample characteristics to reflect the population characteristics. So, this statement too isn't true.

e. There seems to be a relationship between the app and preventing the spread of daycare illness.

Based on this information given, it is evident that the results of this study shows a relationship between the app. It shows a significant decrease in daycare-related illnesses in children of parents who downloaded the app. Hence, the app must have something that reduces the chances of a daycare-related illness in the children of parents who downloaded the app.

Hope this Helps!!!

Find the value of x.<br> 3<br> X<br> x = [?]

I think it would be 2 because it looks like 6 is the total and 3 is a side number so if you were to multiply 3 times 2 it would be 6. I hope this is correct!

3. x + 4y = 30<br> x - 2y = 0
kolbaska11 [484]

Answer:

Step-by-step explanation:

Given that:

x + 4y = 30

x - 2y = 0

Subtracting both equations:

6y = 30

y = 30/6

y = 5

Putting in above equation

x + 4(5) = 30

x + 20 = 30

x = 10

i hope it will help you

Which expression is equivalent to StartFraction (3 m Superscript negative 2 Baseline n) Superscript negative 3 Baseline Over 6 m
Dovator [93]

Option a: \frac{m^{5} }{162n} is the equivalent expression.

Explanation:

The expression is \frac{(3m^{-2} n)^{-3}}{6mn^{-2} } where m\neq 0, n\neq 0

Let us simplify the expression, to determine which expression is equivalent from the four options.

Multiplying the powers, we get,

\frac{3^{-3}m^{6} n^{-3}}{6mn^{-2} }

Cancelling the like terms, we have,

\frac{3^{-3}m^{5} n^{-1}}{6 }

This equation can also be written as,

\frac{m^{5}}{3^{3}6 n^{1} }

Multiplying the terms in denominator, we have,

\frac{m^{5} }{162n}

Thus, the expression which is equivalent to \frac{(3m^{-2} n)^{-3}}{6mn^{-2} } is \frac{m^{5} }{162n}

Hence, Option a is the correct answer.

Find the equation of circle having centre with
GaryK [48]

Step-by-step explanation:

Simply use the general equation of a circle to obtain its equation given the center. Because radius is 5 units, this may be referred to the 3-4-5 triangle, meaning the point on circumference is 3 units across in the x-direction and 4 units up in the y-direction.
