The 1990s and early 2000s could be considered the steroids era in a certain professional baseball​ league, as many players have

admitted to using the drug to increase performance on the field. If a sports writer wanted to compare home run totals from the steroids era to an earlier​ decade, say the​ 1960s, explain why this would be an observational study. Could the writer conclude that it was the steroids that caused the increase in home​ runs? Why or why​ not?

Answer:

Step-by-step explanation:

This could be an observational study because an experiment was not carried out by the research to further verify this hypothesis. Individuals are observed and data is collected from such observation. No effort is made by the researcher to affect the outcome of such results.

This study alone is not enough to conclude about a cause and effect relationship between steroids and the increase in home​ runs as thus study is not randomized and cant control other factors or links bringing about this result.

PLZ HURRY IT'S URGENT!!
Jet001 [13]

Answer:

OPTION C: 60%

Step-by-step explanation:

Chances of raining the next day + Chances that it will not rain = 100%

One of them should definitely be true.

So, if the chance of it raining tomorrow is 40% then there is 60% chance that it will not rain tomorrow.

This can also seen as follows:

Probability of rain tomorrow + Probability of no rain = 1

Given Probability of rain tomorrow = 40% = $ \frac{40}{100} = \frac{2}{5} $

Probability of no rain tomorrow = 1 - Probability of rain tomorrow

⇒ Probability of no rain = 1 - $ \frac{2}{5} $

⇒ Probability of no rain = $ \frac{3}{5} $

Expressing it as percentage: $ \frac{3}{5} \times 100 $ = 60%.

Pani-rosa [81]

Answer:

P(You\ n\ Anna\ n\ Kevin) = \frac{1}{4913}

Step-by-step explanation:

Given

Total\ Employees = 17

To\ Select = 3

Required

Determine the probability of selecting You, Anna and Kevin

Assuming the selection process is fair;

Each employee has a probability of;

Probability = \frac{1}{17}

So:

P(You\ n\ Anna\ n\ Kevin) = P(You) * P(Anna) * P(Kevin)

P(You\ n\ Anna\ n\ Kevin) = \frac{1}{17} * \frac{1}{17} * \frac{1}{17}

P(You\ n\ Anna\ n\ Kevin) = \frac{1}{4913}

MatroZZZ [7]

Answer:  

The second box  

Step-by-step explanation:

The volume of a pyramid can be given by the formula:  V=31​Ah. Where.  A:  Area of the V=(1/3)(B)(h)

multiply both sides by 3

3V=Bh

divide both sides by B

3V/B=h

Therefore, If it is wider it has more space to carry more items such as macaroni.
