A point on the rim of a wheel has a linear speed of 33 cm/s. If the radius of the wheel is 50 cm, what is the angular speed of t
Zigmanuir [339]

Answer:

The angular speed of the wheel in radians per second is 0.66.

Step-by-step explanation:

Recall the following statement:

A linear speed (v) is given by,  

v=\omega \times r                       ...... (1)

Here,  \omega represents the angular speed of the wheel and <em>r</em> represents the  radius of the wheel.

From the given information:

Linear speed (v) = 33 cm/s

Radius of the wheel (r) = 50 cm

Now to find the angular speed in radian per second.

33 =50 \times \omega

Divide both sides by 50.

0.66 rad/sec= \omega

Hence, the angular speed of the wheel in radians per second is 0.66.

Whats x-3+75x compared to or equal to x-75+3x
lbvjy [14]

Answer:

x=-1

Step-by-step explanation:

-3+75x<-75+3x

75x-3<-75+3x

75x-3<3x-7575x−3<3x−75

75x-3-3x<-75

72x-3<-75

72x<-75+3

72x<-72

x=-1

What sample size should be used if we would like to estimate the mean age of the college students at a particular campus with 95
nevsk [136]

Answer: 12

Step-by-step explanation:

The formula to find the sample size is given by:-

n=(\dfrac{z_c\cdot \sigma}{E})^2 , where \sigma is the population standard deviation, z_c is the z-value for the (1-\alpha) confidence interval and E is the margin of error .

As per given , we have

Population standard deviation : \sigma=5.1

z-value for 95% confidence interval : z_c=1.960

Margin of error : E= 3

Then, the required minimum sample :-

n=(\dfrac{(1.96)\cdot (5.1)}{3})^2\\\\\Rightarrow\ n=(3.332)^2=11.102224\approx12

Hence, the required minimum sample size = 12

zlopas [31]

It's 5.

1/2 can also be written as 4/8.

So, it's 3 and 4/8 plus 1 and 4/8.
