Answer:
They each got $3.00
Step-by-step explanation:
7+x = 2(2+x)
7+x = 4 + 2x
-x = -3
x=3
The number -6.75 is rational if it is an integer or decimal. -6.75 is a decimal, so -6.75 is rational, not irrational.

Step-by-step explanation:
Graph the function and observe that the function P(t) increases without bound as x increases.
Answer:
357.5ft^3
Step-by-step explanation:
solve for bottom reticular prism
8 * 10 * 4
320ft^3
solve for top triangular prism
((3*5)/2)*5
37.5ft^3
add top and bottom
320+37.5
357.5ft^3
Answer:
+/- 1.9983
Step-by-step explanation:
The critical values for a confidence interval for the population mean, with population standard deviation not known, are obtained from the student's t distribution.
The sample size is given as 64. The degrees of freedom will thus be;
sample size - 1 = 64 - 1 = 63
The confidence level is given as 95%. The level of significance will thus be;
100 - 95 = 5%.
The area in the right-tail will thus be 2.5%. Therefore, we looking for a t-value such that the area to its right is 2.5% and the degrees of freedom being 63. From the t-tables we have;
+/- 1.9983
