D
The correct option is D
Step-by-step explanation:
From the question we are told that
The sample size is 
The number that developed nausea is X = 50
The population proportion is p = 0.20
The null hypothesis is 
The alternative hypothesis is 
Generally the sample proportion is mathematically represented as
Generally the test statistics is mathematically represented as
=> 
=> 
=>
The p-value obtained from the z-table is
Given that the 
then we fail to reject the null hypothesis
2 x 5/9 equals and improper fraction of 1 1/9
Answer:
9 days
Step-by-step explanation:
Experimental probability is the number of times an event occurs divided by the total number of trials of the event.
We know the experimental probability, based on past data, that rain will fall 20% chance.
So, one can expect, that in the next 45 days, rain will fall 20% of the days, according to our experimental probability.
First, we find decimal equivalent of 20%. We divide by 100:
20% = 20/100 = 0.2
Now we multiply this with the number of days:
0.2 * 45 = 9
Thus,
One can expect it to rain 9 days
The given equation is in point-slope form. The line that represents this equation passes through the point (4,1) and has a slope of (3/2).
One way to graph this quickly would be to plot the point (4,1). Move 2 units to the right from this point, and then (without picking up your pen) 3 units up. Plot a dot there. Connect the 2 points with a straight line.
