Answer :

Part 17: The value of x is 5.

Part 18: The value of x is 2°.

Step-by-step explanation :

<u>Part 17:</u>

Given:

Length SR = 2x - 9

Length RQ = x + 6

Length SQ = 12

Now we have to determine the value of x.

Length SQ = Length SR + Length RQ

12 = (2x - 9) + (x + 6)

12 = 2x - 9 + x + 6

12 = 3x - 3

3x = 15

x = 5

The value of x is 5.

<u>Part 18:</u>

Given:

∠MLK = 81x - 2

∠HLK = 54x + 2

∠MLH = 50°

Now we have to determine the value of x.

∠MLK = ∠HLK + ∠MLH

81x - 2 = 54x + 2 + 50°

81x - 2 - 54x - 2 = 50°

27x - 4 = 50°

27x = 54°

x = 2°

The value of x is 2°

Construct a 99% confidence interval for the population standard deviation of white blood cell count (in cells per microliter). A
kogti [31]

Answer:

The correct option is 1.148 < σ < 6.015

Explanation:

The 99% confidence interval for the standard deviation is given below:

\sqrt{\frac{(n-1)s^{2}}{\chi^{2}_{\frac{0.01}{2} }} }

Where:

\chi^{2}_{\frac{0.01}{2} }=18.548

\chi^{2}_{1-\frac{0.01}{2}}=0.676

Therefore, the 99% confidence interval is:

\sqrt{\frac{(7-1)2.019^{2}}{18.548} }

1.148

Therefore, the option 1.148 < σ < 6.015 is correct

If you vertically shift the linear parent function, f(x)=x up four units , what is the equation of the new function
OverLord2011 [107]
Shifting in the y direction is as simple as adding the shift, ie., 

f(x) = x+4.

In the x direction it is trickier because then you have to replace x by (x-a) where a is the shift to the right... (but that wasn't asked here).
