The period of oscillation of a pendulum is
T=2 \pi  \sqrt{ \frac{L}{g} }
Where L is the length of the pendulum and g=9.81 m/s^2 the gravitational acceleration.
Re-arranging the formula and using T=1.0 s, we find the length of the pendulum:
L= \frac{T^2g}{4 \pi^2}=0.25 m

Vesna [10]

Given:

The cost to install x number of central air conditioning units for a company is given by the function

C(x)=\dfrac{4000x+1300}{3}

To find:

The cost to install 45 air conditioners.

Solution:

We have,

C(x)=\dfrac{4000x+1300}{3}

Putting x=45, we get

C(45)=\dfrac{4000(45)+1300}{3}

C(45)=\dfrac{180000+1300}{3}

C(45)=\dfrac{181300}{3}

C(45)=60433.3333...

C(45)\approx 60433.33

Therefore, the cost to install 45 air conditioners is $60433.33.

Suppose that 1 month before the election a random sample of 500 registered voters are surveyed. From this sample 270 indicate th
Aleonysh [2.5K]

Answer:

[ 0.4964, 0.5836 ]

Step-by-step explanation:

Data provided in the question:

Total sample size = 500

person voting for smith = 270

thus,

P( person voting for smith ), p = \frac{270}{500} = 0.54

Confidence level = 95%

now,

standard error, SE = \sqrt{\frac{p(1-p)}{n}

or

SE = \sqrt{\frac{0.54(1-0.54)}{500}

or

SE = 0.0223

now,

Confidence interval = p ± ( z × SE )

here,

z value for 95% confidence interval is 1.96

Confidence interval = [ 0.54 - ( 1.96 × 0.0223 ), 0.54 + ( 1.96 × 0.0223 ) ]

= [ 0.54 - 0.0436 , 0.54 + 0.0436 ]

= [ 0.4964, 0.5836 ]
