Answer:
Length of diagonal of picture = 15.30 inches
Step-by-step explanation:
Given that:
Side lengths of picture frame = 12 inches by 9.5 inches
As the picture is rectangular, the diagonal will form hypotenuse of right angled triangle.
Using Pythagorean theorem;
a²+b²=c²
Putting the values in the theorem
Taking square root on both sides
Hence,
Length of diagonal of picture = 15.30 inches

Answer:
(0.500, 1.090)
Step-by-step explanation:
Given that a university dean is interested in determining the proportion of students who receive some sort of financial aid.
A sample of (random) 200 students taken and 118 were found out receiving financial aid.
Sample proportion p =
For margin of error we use Z critical value as this is proportion and also sample size is large. np and nq both are greater than 5.
So margin of error = 2.58*std error = 0.090
Confidence interval
=
I’m not sure but good luck
Anytime you multiply or divide both sides of the inequality, you must “flip” or change the direction of the inequality sign. This means that if you had a less than sign <, it would become a greater than sign >. Likewise, if you started with >, it would become <.
