Answer:
7 integers
Step-by-step explanation:
The inequality to solve is
We can do algebra and solve this:
If we solve , we will get the intercepts. So:
<em>Since, the inequality is less than, the solution set is all numbers between -4 and 4. So</em>
<em>-4 < n < 4</em>
<em />
<em>*note: -4 and 4 is NOT included, so the integers in the range are:</em>
<em>-3, -2, -1, 0, 1 , 2, 3</em>
<em>Which is </em><em>7 integers.</em>
Answer:
Third option: 80 people.
Step-by-step explanation:
Let be "x" the number of people that were surveyed.
You know that 48 people chose winter as their favorite season and these amount of people are the 60% of those questioned.
Knowing this, you can calculate the number of people that were surveyed with this procedure:
Therefore, 80 people were surveyed. This matches with the third option.
Answer:
P = 0.018
Step-by-step explanation:
In this problem, the null and alterantive hypothesis are:
If the sample has a size of n = 40, the degrees of freedom are 40-1 = 39.
If the value of the test statistic is t = 2.463, we can look up in a t-table to find the p-value. In this test, because the mean can be bigger than 73 or smaller than 73, we have to do a two-tailed test.
For a two-tailed test for t = 2.463 and df = 39, the P-value is P = 0.018.
The loan's effective rate and interest compound every two months then the value of n would be 6.
Given that,
When calculating a loan's effective rate, the interest compounds every two months.
We have to determine,
What value of n do you plug into your equation?
According to the question,
The calculation of compounded interest would be derived with the following formula:
In a year there are 12 months and when the interest rate is said to be compounded every two months then it implies that the number of months would be 6 months.
Then,
The value of n is,
Hence, The loan's effective rate and interest compounds every two months then the value of n would be 6.
