Answer:

See below

Step-by-step explanation:

Given there are 56 M&M's:

  • Expected Value of Blue = 56(0.24) = 13.44
  • Expected Value of Brown = 56(0.14) = 7.84
  • Expected Value of Green = 56(0.16) = 8.96
  • Expected Value of Orange = 56(0.20) = 11.20
  • Expected Value of Red = 56(0.13) = 7.28
  • Expected Value of Yellow = 56(0.14) = 7.84

Remember to use np to calculate expected value! This will especially be helpful if you are conducting a chi-squared test of independence.

It is desired to draw blood 3 cm up a capillary tube. Assuming a contact angle of 0 degrees and a blood density of 1060 kg/m3, w
JulijaS [17]

Answer:

If we assume a temperature of 20ºc and the blood interfacial surface tension is similar to water interfacial surface tension, the diameter of the capillary tube should be 0.933mm.

Step-by-step explanation:

The Jurin law describes the height a fluid can reach in a capillary tube. This law can be written as:

H=\displaystyle\frac{2\gamma cos(\theta)}{\rho gr}

where γ is the interfacial surface tension, θ is the contact angle with the fluid, ρ is the fluid density, g is the gravity acceleration and r is the tube radius.

If we assume that the interfacial surface tension of blood and water are almost the same, γ=0,0728 N/m at 20ºc. Therefore the diameter of the tube will be:

D=2r=\displaystyle\frac{4\gamma cos(\theta)}{\rho gH}=0.933\cdot 10^{-3}m

Please i need the step-by-step solution please thank you ​

Answer:

Question 6: -8

Question 7: C

Step-by-step explanation:

Question 6:

The reason question 6 is -8 is because of the distance in between each number, e.g -7 and -15. This is not to be confused with + 8 each time that would make the sequence 9, 18, 27.

Question 7:

The way we solve this question is using the nth term rule, whatever is before the n is the times tables we follow. So if it is 2n the sequence would be 2, 4, 6, 8 etc. However when we add something like the -2 we do the 2 times tables but this time we -2 for each one. Example: 2 - 2 = 0 so the first number of the sequence is 0, Example 2: 4-2 = 2 so the second number of the sequence is 2.
