The last term of this series is:
The sum of the first n-terms of the series is calculated using the formula,
Answer:
Solve for x by simplifying both sides of the equation, then isolating the variable.
x=−845
Step-by-step explanation:
The slope is 1 because you do 4 minus 3 and 3 minus the 2
Answer:
a) if you where to go down two to the left one it would connect from a to b and from b to c. these triangles all equal to each other.
b) the inital value is 63 since you y intercept is 63 and your slope is 2. 63 is the distance at 0 mins over time the slope is 2 per min
Answer:
Step-by-step explanation:
Hello!
The variable of interest is X: number of individuals that hold multiple jobs in a sample of 225.
And you need to calculate the probability of the proportion of individuals being between 0.14 and 0.18.
Considering that the parameter of interest is the proportion and the sample is large enough you can use the standard normal approximation to calculate this interval.
Unfortunately, there is no given value for the population proportion of individuals that have multiple jobs. Let's say, for example, that his proportion is 10%.
You can symbolize the probabilities as:
P(0.14≤X≤0.18)= P(X≤0.18)-P(X≤0.14)
Using the approximation of the standard normal you can standardize these proportion values:
P(Z≤(0.18-0.1)/√[(0.1*0.9)/225])-P(Z≤(0.14-0.1)/√[(0.1*0.9)/225])
P(Z≤4)-P(Z≤2)
Now you have to look for the corresponding values in the table of the Z distribution (right table, positive numbers of Z)
P(Z≤4)-P(Z≤2)= 1 - 0.97725= 0.02275
I hope it helps!
