Answer:

$\huge\boxed{w=5}$

Step-by-step explanation:

$6w=30\qquad|\text{divide both sides by 6}\\\\\dfrac{6\!\!\!\!\diagup w}{6\!\!\!\!\diagup}=\dfrac{30}{6}\\\\w=5$

The answer would be 8900
Reason: when you round to 2 significant figures you are trying to reduce the number to 2 digits and the rest will become 0 to indicate a place value

The ages (in years) and weights (in pounds) of all wide receivers for a football team are listed. Find the coefficient of variat

IceJOKER [234]

Answer:

The coefficient of variation for the weight and age are 5.9% and 10.6%.

Step-by-step explanation:

The coefficient of variation (CV) is well defined as the ratio of the standard deviation to the mean. It exhibits the degree of variation in association to the mean of the population.

The formula to compute the coefficient of variation is:

$CV=\frac{\sigma}{\mu}\times 100\%$

Here σ = standard deviation and µ = mean.

Compute the mean and standard deviations of the two data set in Excel using the following functions.

Mean=AVERAGE()

Standard deviation=STDEV.S()

Consider the Excel sheet attached.

The mean and standard deviation of weight are:

Mean = 202, Standard deviation = 11.87

And the mean and standard deviation of weight are:

Mean = 25.88, Standard deviation = 2.75

Compute the coefficient of variation for the weight as follows:

$CV_{weight}=\frac{\sigma}{\mu}\times 100\%$

$=\frac{11.87}{202}\times 100\%\\\\=5.87624\\\\=5.9\%$

Compute the coefficient of variation for the age as follows:

$CV_{age}=\frac{\sigma}{\mu}\times 100\%$

$=\frac{2.75}{25.88}\times 100\%\\\\=10.62597\\\\=10.6\%$

Thus, the coefficient of variation for the weight and age are 5.9% and 10.6%.

Help pls pls pls pls

adelina 88 [10]

Answer:

m∠1= 41°

m∠2= 85°

m∠3= 95°

m∠4= 85°

m∠5= 36°

m∠6= 49°

m∠7= 106°

Step-by-step explanation:

To find m∠2

95+m∠2= 180

-95 - 95

m∠2= 85

To find m∠4

Since they are vertical angles, m∠2=m∠4, that means that they are both 85°

To find m∠1

There is four angles in this shape, so the sum is 360 degrees.

90+144+85+m∠1= 360

319+m∠1= 360

-319 -319

m∠1= 41°

To find m∠5

144+m∠5= 180

-144 -144

m∠5= 36°

To find m∠6

m∠5+m∠3+m∠6= 180

36+95+m∠6= 180

131+m∠6= 180

-131 -131

m∠= 49°

To find m∠7

You need to find the sum of the other unidentified angle.

m∠6+m∠=180

49+m∠= 180

-49 -49

m∠= 131

Now you need to find the sum of all the angles in the quadrilateral to get the measure for angle 7.

131+38+85+m∠7= 360

254+m∠7= 360

-254 -254

m∠= 106°
