Option A is correct: A. The first kind of error would be saying that your friend can tell the difference between the two kinds of peanut butter, when she really can't.
Step-by-step explanation:
The null hypothesis: the lady is just guessing and should get about half right.
So the first kind of error (when you reject the null hypothesis when it is actually true): the lady is not just guessing and can tell the difference between the two kinds of peanut butter, whereas in reality, she can't tell the difference and is just guessing randomly.

11-6.25=4.75
Answer:
Step-by-step explanation:
y = 1/8x - 1.....sub this back in for y in the other equation
-5x + 4y = -13
-5x + 4(1/8x - 1) = -13
-5x + 1/2x - 4 = -13.....multiple everything by 2 to get rid of the fraction
-5x(2) + 1/2x(2) - 4(2) = -13(2)
-10x + 1x - 8 = - 26
- 9x = -26 + 8
-9x = - 18
x = 18/9
x = 2.....now sub 2 in for x in either of the original equations to find y
y = 1/8x - 1
y = 1/8(2) - 1
y = 1/4 - 4/4
y = -3/4
so ur solution is : (2,-3/4) <===
