Please take 50 points please help me <br>please ​
ch4aika [34]

I am using a calculator for this question so hopefully this helps + I added working out just in case.

a) mean - 124 (add them all together then divide by 25)

b) standard deviation - 7.776888838 (7.76 to d.p)

c) the person might have eaten foods that increase or decrease the BP so every time they took their blood pressure, it might not have been done as the same routine as others (if this makes sense). Also, some blood pressures are lower than others like for example some might go down to 110 but others go all the way up to like 132, does why I said that they might have eaten food or done activites that increases the blood pressure.

Lightbulb A is marked "25 W 120V, "and lightbulb B is marked "100 W 120V " These labels mean that each lightbulb has its respect
Dovator [93]

The cost of running the lightbulb A for 30 days at 0.110 per KWh is 1.98

<h3>How to determine the energy </h3>

We'll beging by calculating the energy used by lightbulb A. This can be obtained as follow:

  • Power (P) = 25 watts = 25 / 1000 = 0.025 KW
  • Time (t) = 30 days = 30 × 24 = 720 h
  • Energy (E) =?

E = Pt

E = 0.025 × 720

E = 18 KWh

<h3>How to determine the cost for running the bulb for 30 days</h3>

The cost of running the bulb for 30 days can be obtained as follow:

  • Cost per KWh = 0.11
  • Energy (E) = 18 KWh
  • Cost =?

Cost = energy × Cost per KWh

Cost = 18 × 0.11

Cost = 1.98

Calculate the period (T) of uniform circular motion if the velocity is 40.0 m/s and centripetal acceleration is 20.0 m/s2.
kirill [66]
T is the time for a whole round.

centripetal acceleration = V^2/R,

20 = 40^2 / R, find R = 40^2/20 = 40*40/20 = 80 m, right?

Now, one round is L = 2*pi*R = 2*pi*80 = 160*pi

And T = L/v (distance/speed) = 160*pi/40 = 4*pi seconds, or ~ 12.57 s
