<span>There are 100 possible pairs of numbers.
Half of them start with an even number so only 50 have a first odd number.
Of those remaining 50, half of those have an odd second number.
Leaving 25 of the original 100 to have two odd numbers.
P= 25/100=1/4</span>
Answer:
B (0.312, 0.364)
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of 
, and a confidence interval 
, we have the following confidence interval of proportions.
In which
z is the zscore that has a pvalue of 
For this problem, we have that:
1289 randomly selected American adults responded to this question. This means that 
.
Of the respondents, 436 replied that America is doing about the right amount. This means that 
.
Determine a 95% confidence interval for the proportion of all the registered voters who will vote for the Republican Party.
So 
, z is the value of Z that has a pvalue of 
, so 
.
The lower limit of this interval is:
The upper limit of this interval is:
The 95% confidence interval is:
B (0.312, 0.364)
Answer:
she cut 6 inches of tape
Step-by-step explanation:
you can start by multiplying 3/8 and 6/1 which gives you 6
Answer:
so ......when you write the equation for this question,
the original height (H) = current height + the decreased height
i.e.
H= 347m + 182m
H = 529 m
so the original height of the helicopter is 529 meters
Step-by-step explanation:
Answer: x > 5
Step-by-step explanation: To solve for <em>x</em> in this inequality, our goal is the same as it would be if this were an equation, to get x by itself on one side.
Since 3 is being subtracted from x, we add 3 to
both sides of the inequality to get x > 5.
When graphing x > 5, we have an open circle on 5 and the
open circle tells us that 5 is not part of our answer.
Then we draw an arrow going to the right to represent
all possible solutions to this inequality, any number greater than 5.
