For what numbers theta is f(theta)=cot(theta) not defined?

1 answer:

5 0

<span>
as cosec theeta is inverse of sin theeta:
so
csc0=1/sin0
and sin0=0 when 0={0.pi,and 2pi}
when 0=0.pi,and 2pi</span>

A study was done to determine the average number of homes that a homeowner owns in his or her lifetime. For the 60 homeowners su

const2013 [10]

Answer:

D) (3.67, 4.73)

Step-by-step explanation:

Confidence Interval for the true average number of homes that a person owns in his or her lifetimecan be calculated using M±ME where

M is the average number of home owned (4.2)

ME is the margin of error from the mean

And margin of error (ME) can be calculated as

ME= $\frac{z*s}{\sqrt{N} }$ where

z is the corresponding statistic in the given confidence level(1.96)

s is the standard deviation of the sample(2.1)

N is the sample size (60)

Putting the numbers we get ME= $\frac{1.96*2.1}{\sqrt{60} }$ ≈0.53

Then the 95% confidence interval is 4.2±0.53 or (3.67, 4.73)

german

Answer:

range is between 55.5 to 64.5

Step-by-step explanation:

Horn lengths of Texas longhorn cattle are normally distributed. The mean horn spread is 60 inches with a standard deviation of 4.5 inches

68% is 1 standard deviation from mean

To get the range of 1 standard deviation we add and subtract standard deviation from mean

mean = 60

standard deviation = 4.5

60 - 4.5= 55.5

60+4.5 = 64.5

1 standard deviation is between 55.5 to 64.5

That is 68% range is between 55.5 to 64.5

Need help ASAP to this math question about how many gallons it will take to fill a pool

NARA [144]

1 cubic foot = 7.48 gallons

hence
$\frac{7.48 gal}{1 ft^3} =1$

unit conversion
$\frac{3000 ft^3}{} \times \frac{7.48 gal}{1 ft^3} = 3000 \times 7.48 gal$

3000 x 7.48 =22440

What is the equation of the graphed line in point-slope form?

Flura [38]

We first need to find the gradient of the line
$\frac{y_{2}- y_{1} } {x_{2}-x_{1} } = \frac{-3-1}{-3-3}= \frac{-4}{-6}= \frac{2}{3}$

From the graph, we see the graph intercepts y-axis at -1

Hence, the equation of the line is $y= \frac{2}{3}x-1$
