Answer:

p>31/60

−3−(−3p+7)>6p+21(1−3p)

Step 1: Simplify both sides of the inequality.

3p−10>−57p+21

Step 2: Add 57p to both sides.

3p−10+57p>−57p+21+57p

60p−10>21

Step 3: Add 10 to both sides.

60p−10+10>21+10

60p>31

Step 4: Divide both sides by 60.

60p

60

A 90 % confidence interval for the average salary of all CEOs in the electronics industry was constructed using the results of a
alisha [4.7K]

Answer: D) Increase the sample size and decrease the confidence level.

Step-by-step explanation:

A reduced interval width means that the data is more accurate. This can only be achieved if the sample size is increased because a larger sample size is able to capture more of the characteristics of the variables being tested.

A smaller confidence interval will also lead to a reduced interval width because it means that the chances of the prediction being correct have increased.

In a free-fall experiment, an object is dropped from a height of h = 400 feet. A camera on the ground 500 ft from the point of i
PilotLPTM [1.2K]
Hmmm the object, is at rest, when dropped, so it has a velocity of 0 ft/s

the only force acting on the object, is gravity, using feet will then be -32ft/s²,


was wondering myself on -32 or 32.. but anyhow... we'll settle for the negative value, since it seems to be just a bit of convention issues

so, we'll do the integral to get v(t) then

\bf \displaystyle \int -32\cdot dt\implies -32t+C&#10;\\\\\\&#10;\textit{object moves from \underline{rest}, so velocity is 0 at 0secs}&#10;\\\\\\&#10;-32(0)+C=0\implies C=0\implies \boxed{v(t)=-32t}&#10;\\\\\\&#10;\textit{now to get the positional s(t)}&#10;\\\\\\&#10;\displaystyle \int -32t\cdot dt\implies -16t^2+C&#10;\\\\\\&#10;\textit{the initial \underline{position} was 400ft away at 0secs}&#10;\\\\\\&#10;-16(0)^2+C=400\implies C=400\implies \boxed{s(t)=-16t^2+400}

when will it reach the ground level? let's set s(t) = 0

\bf s(t)=-16t^2+400\implies 0=-16t^2+400\implies \cfrac{-400}{-16}=t^2&#10;\\\\\\&#10;25=t^2\implies \boxed{5=t}
