Answer:
t = –3.382
Step-by-step explanation:
Claim: FICO credit scores are greater than 675
Thus, x = 675
We are given:
Sample size = n = 50
Sample Mean = u = 719
Sample Standard deviation = s = 92
The formula to find the t-statistic is:
Using the above values, we get:
Thus, the value of test statistic is -3.382. So 3rd option gives the correct answer.

Answer:
1
Step-by-step explanation:
When dividing one fraction by another, the best way to solve it is to multiply by the reciprocal. The reciprocal just flipping the fraction over. So you would leave the 6/7 and the multiply by 14/12( because you are multiplying by the reciprocal). When you do that, you then can just multiply the top and the bottom to form one fraction. The numerator is 6*14 = 84, and the denominator is 7*14 = 84. So you are left with 84/84 which anything over itself is equal to one.
Hope this helps!
Answer:
1 2 = 2 4 = 3 6 = 4 8 = etc. All of these fractions are located at the same point on the number line. Therefore, they represent the same number. From the paper folding exercises, we see that increasing both numerator and denominator of a fraction by the same factor gives an equivalent or equal fraction.
Hope this helps :) Just know I tried.
