Answer:

n = 4

x = 2

p = 38\%

q = 62\%

Step-by-step explanation:

Required

Find n, x, p and q

n always represent the population surveyed;

So:

n = 4

x represents the sample from the population

So:

x = 2

p always represents the given proportion

p = 38\%

Solving for q

p + q = 1

q = 1 - p

q = 1 - 38\%

q = 62\%

The football team has 2 large water containers. Each container holds 345π in3 of water. Each player is given a cylindrical water
raketka [301]

Answer:

They'll be able to get 34 bottles from the containers.

Step-by-step explanation:

Since the bottles are cylindrical we can calculate their volume by using the following formula:

V = base_area*h

V = \pi*(r^2)*h

r = d/2 = 4/2 = 2 inches

V = 3.14*(2^2)*5 = 3.14*4*5

V = 3.14*20 = 62.8 inches^3

In order to know how many full bottles the players will get we need to divide the total volume of the containers, which is given by the sum of the volume of each container, and divide it by the volume of each bottle. We have:

bottles = (345*pi + 345*pi)/62.8 = 690*pi/62.8 = 2,166.6/62.8 = 34.5

Since the problem wants the amount of full bottles we only take the integer part, so they will be able to get 34 bottles from the containers.

I need some help with this:)I'll apreciate the answers.
Travka [436]
Part A: The discounted monthly fee is $22.49 (original cost of $29.99 multiplied by 75%, the amount the customer would pay since 25% is discounted.) Since you would also pay $44.99 for setup, your equation is $44.99+$22.49m Part B: Add 1.08 (108%; the customer pays 100% of the cost plus 8% more for tax) to your equation for the sales tax. 1.08(44.99+22.49m) Part C: Plug in 4 for m (m represents months). 1.08(44.99+22.49•4) 1.08(44.99+89.96) 1.08(134.95) $145.75 Hope that helps. Let me know if you need more assistance :)

Please answer with process
laila [671]

\mathsf{Given : a - b = 5}

\mathsf{Squaring\;on\;both\;sides,\;we\;get :}

\mathsf{\implies (a - b)^2 = 5^2}

\mathsf{\implies a^2 + b^2 - 2(a.b) = 25}

\mathsf{Given : a^2 + b^2 = 29}

\mathsf{\implies 29 - 2(a.b) = 25}

\mathsf{\implies 2(a.b) = 29 - 25}

\mathsf{\implies 2(a.b) = 4}

\mathsf{\implies (a.b) = 2}
