A farmer of a large apple orchard would like to estimate the true mean number of suitable apples produced per tree. He selects a

random sample of 40 trees from his large orchard and determines with 95% confidence that the true mean number of suitable apples produced per tree is between 375 and 520 apples. If the farmer had selected 160 trees from his large apple orchard rather than 40 trees, what effect would this have had on the margin of error?
A) It would have doubled.
B) It would have been cut in half.
C) It would have remained the same.

MO bisects m<br> A. x = 13,<br> B. x = 13, <br> C. x = 14, <br> D. x = 14,
nadezda [96]
For the given question above, the full question must have read as:
<span>MO bisects m<LMN,<LMO =6x-20 and <NMO 2x+36. Solve for x and find m<LMN.  The diagram is not to scale.
</span>
<span>If MO bisect the angles, then the 2 resulting angles are equal in size so you will have:
6x - 20 = 2x + 36

Solve:
</span>6x - 20 = 2x + 36



The answer would be: x = 14, <LMN=128

larisa [96]

Answer:

1) 5 2) 6 3) 1.25 or -1.75

Step-by-step explanation:

1. x^2 - 25 = 0

x^2 - 25 = 0

First, add 25 to both sides!

x^2 = 25

Now square root both sides.

x = 5

2.  (x-2)^2 = 16

First, square root both sides.

(x-2) = 4

Add 2 on both sides.

(x) = 6

x = 6

3. Quadratic Formula = -b ± \sqrt{b^{2}-4ac } / 2a

Substitute in:

-6 ±\sqrt{7^{2} -4(2)(6)} / 2(2)

-6±\sqrt{49 - 48} / 4

Both forms:

-6 + \sqrt{1} / 4

5 / 4 = 1.25

Negative:

-6 - 1 / 4

-7 / 4 = -1.75
