Need help I got 23,294 as the answer but it’s not an option please explain how you got the answer.
OLEGan [10]

Answer:

A

Step-by-step explanation:

Calculation seems correct to me, with d the distance and h the height of the plane, and i got the same value. Closest value is A tho, so i'd stick with it.

If you want to be pedantic about it, you can always divide the heigth by each value, and get the inverse tangent of each value. With A you get 17.995 which seems the best value you get

What is 2 = 8 − 6/4x solved?
KengaRu [80]

Answer:

x=4

General Formulas and Concepts:

  • Order of Operations: BPEMDAS
  • Equality Properties

Step-by-step explanation:

<u>Step 1: Define equation</u>

<u />2=8-\frac{6}{4} x<u />

<u />

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Subtract 8 on both sides:                    -6=-\frac{6}{4} x
  2. Divide both sides by -6/4:                   4=x
  3. Rewrite:                                                x=4

<u>Step 3: Check</u>

<em>Plug in x to verify it's a solution.</em>

  1. Substitute:                    2=8-\frac{6}{4}(4)
  2. Multiply:                        2=8-6
  3. Subtract:                       2=2

A Gallup Poll found that 51% of the people in its sample said "yes" when asked, "Would you like to lose weight?" Gallup announce
Nata [24]

Answer:

(a) 95% confidence interval for the percent of all adults who want to lose weight is (48%, 54%) that is between 48% and 54%

(b) to say that we have 95% confidence in this interval means that there is 95% chance that the true percentage of all adults who wants to lose weight falls in this interval.

Step-by-step explanation:

The question is missing, complete question is below:

A Gallup Poll found that 51% of the people in its sample said "yes" when asked, "Would you like to lose weight?" Gallup announced: "With 95% confidence for results based on the total sample of national adults, one can say that the margin of sampling error is ± 3%."

(a) What is the 95% confidence interval for the percent of all adults who want to lose weight?

(b) What does it mean to say that we have 95% confidence in this interval?

Confidence Interval can be calculated using p±ME where

  • p is the sample proportion of national adults who want to lose weight (51%)
  • ME is the margin of sampling error (± 3%)

A box of 100 computer chips contains eight defective chips. suppose we selected a random sample of 10 chips from that box. find
leonid [27]
N = # of chips = 100
M = # of defective chips = 8
S = sample size = 10

a) P(X ≥ 1) = 1 - [((N-M)! / (N-M-S)!) / (N! / (N-S)!)] ≈ 0.583
b) P(X = 10) = 0 (because S > M)
c) P(X = 9) = 0 (because 9 > M)
d) P(X = 0) = 1 - P(X ≥ 1) ≈ 0.417
