Answer:
The 90% level of confidence interval For the Population proportion
(0.6569 ,0.7031)
Step-by-step explanation:
<u><em>Explanation</em></u>:-
Given sample size 'n' = 1100
Given sample proportion
The 90% level of confidence interval For the Population proportion is determined by
90% of level of significance Z-value
On calculation , we get
(0.68 -0.0231 ,0.68 +0.0231)
(0.6569 ,0.7031)
<u><em>Final answer</em></u>:-
The 90% level of confidence interval For the Population proportion
(0.6569 ,0.7031)
La Mamá de la mamá de la mamá de la mamá de la mamá
2(4*7)
this is an expression
if you want to solve it
you would multiply 4 by 7 which gives you 28
then double 28
you would multiply 28 by 2
which then gives you an answer of 56
Answer:
a. $45.86
b. $43.87
c. Percentage change = -4.40%)
Step-by-step explanation:
a. Let the price of share at the beginning of first year be represented with X
Now, Price of company's share dropped by 3.50% at the end of first year.
So, Price of share at the end of first year = x - 3.5% of x
= x - 0.035x
= 1x - 0.035x
= 0.965x
But it is equal to $44.25
=> 0.965x = 44.25
x = 44.25 / 0.965
x = 45.8549223
x = $45.86
b. During second year price of share decreased by $1.99. Therefore, Price of share at the end of second year = $45.86 - $1.99 = $43.87
c. Percentage change in the price of shares over two years = {(45.86 - 43.87)/45.86} *100
= (1.99/45.86)*100
= 0.04339294 * 100
= 4.40%
Now, as price of shares has dropped, the percentage change will be negative. (Δ% = -4.40%)
So, there is a rectangular park with longer side (length) 150 yards and shorter side (width) 125 yards.
so walking around the rectangular park once is like covering the Perimeter (p) of the rectangular park.
So, lets find the perimeter of the park.
Perimeter of rectangle = 2 ( l + w)
= 2 ( 150 + 125 )
= 2 * 275
= 550 yards
Now, walking around the park two times is like doubling the Perimeter of the rectangle. So, when Debbie walks around the park 2 times, he covers the perimeter of the rectangular field twice.
i.e. Debbie walked 2 * Perimeter
= 2 * 550
= 1100 yards
Now, If Debbie wanted to walk 1,000,000 yards, she has to walk the rectangular park (1,000,000 / the Perimeter of the park)
i.e. 1,000,000 / 550
= 1818.18 times
So,
(a) she walks 1100 yards
(b) She have to walk 1818.18 times
