Answer:A rubric is a grading tool that describes the criteria, or "what counts," for the assignment.  It also describes each of the criteria according to gradations of quality, with descriptions of strong, middling, and problematic student work.  The criteria are listed in the column on the left.  The numbers in the top row indicate quality, with 3 being the best.   The number 0 is something everyone wants to avoid.  Students may use the rubric as a check list to determine if the writing meets the criteria of the assignment.

Suppose the weights of the Boxers at this club are Normally distributed with a mean of 166 pounds and a standard deviation of 5.
lesya [120]

Answer:

0.1994 is the required probability.      

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 166 pounds

Standard Deviation, σ = 5.3 pounds

Sample size, n = 20

We are given that the distribution of weights is a bell shaped distribution that is a normal distribution.

Formula:

z_{score} = \displaystyle\frac{x-\mu}{\sigma}

Standard error due to sampling =

=\dfrac{\sigma}{\sqrt{n}} = \dfrac{5.3}{\sqrt{20}} = 1.1851

P(sample of 20 boxers is more than 167 pounds)

P( x > 167) = P( z > \displaystyle\frac{167 - 166}{1.1851}) = P(z > 0.8438)

= 1 - P(z \leq 0.8438)

Calculation the value from standard normal z table, we have,  

P(x > 167) = 1 - 0.8006= 0.1994 = 19.94\%

0.1994 is the probability that the mean weight of a random sample of 20 boxers is more than 167 pounds

Average serving size is 500mls which is 1050kj.
astra-53 [7]

Answer:

  2625 kJ

Step-by-step explanation:

We assume the energy is proportional to the volume:

  energy/volume = 1050 kJ/(500 mL) = E/(1250 mL)

Multiply by 1250 mL:

  E = (1250/500)(1050 kJ) = 2625 kJ

The number of kJ in 1.25 L of Lemon Squash is 2625 kJ.

Please help to solve this<br>Find H.C.F <br>m^3 - 1, m^4 + m^2 + 1, m^2+ m + 1​
Nikitich [7]

Answer:

m^2+m+1

Step-by-step explanation:

  • m^3 - 1= (m-1)(m^2+m+1)
  • m^4 + m^2 + 1= m^4+2m^2+1 - m^2= (m^2+1)^2 -m^2= (m^2+m+1)(m^2-m+1)
  • m^2+ m + 1​

HCF= m^2+m+1 which is the factor of all three polynomials
