Answer: 0.0051
Step-by-step explanation:
Given the following :
Average Population weight (m) = 190
Population standard deviation (σ) = 35
Total weight of 25commuters (x) = 5200
Sample mean = 5200 /25 = 108
Sample standard deviation = standard error :
σ / √n = 35/√25 =
35/5 = 7
Zscore = (x - m) / standard error
Zscore = (208 - 190) / 7
Zscore = 18 / 7
= 2.57
P( Z > 2.57) = 1 - p(Z < 2.57)
P(z < 2.57) = 0.9949
1 - p(Z < 2.57) = 1 - 0.9949 = 0.0051
Answer:
B
Step-by-step explanation: 68+x+x=180. subtract 68 from both sides, and simplify the x's. so 2x=112. than divide by 2. x=56

Answer:
<h2>$42</h2>
Step-by-step explanation:
By definition, Markup is the difference between a product's selling price and cost as a percentage of the cost.
For example, if a product sells for $125 and costs $100, the additional price increase is ($125 – $100) / $100) x 100 = 25%.
Given data
firstly let us solve for 40% of $30
=40/100*30
=0.4*30
=$12
therefore the sale price will be the markup rate plus the initial price
<em>Hence the you will have to pay 12+30=$42</em>
Take into account the the Earths gravity is 9.8 meters a second
