Answer:
x=12
Step-by-step explanation:
9x-14=2(3x+11)
9x-14=6x+22
9x-6x=22+14
3x=36
x=36/3=12
-ratio
-interval
-nominal
-ordinal
Answer:
Nominal
Step-by-step explanation:
-Ratio level of measurement means that you can build a fraction.
-interval level of measurement means that the distance that exists between values is important.
-Nominal means that the values are only named and there is no organization.
-Ordinal means that the values can be ordered by rank.
According to this, the answer is that classifying the fruit in a basket as apple, orange, or banana, is an example of the nominal level of measurement.
Answer:
(-6,4)
Step-by-step explanation:
The equations are:
![x^2+4y^2=100\\4y-x^2=-20](https://tex.z-dn.net/?f=x%5E2%2B4y%5E2%3D100%5C%5C4y-x%5E2%3D-20)
Solving for x^2 of the 2nd equation and putting that in place of x^2 in the 2nd equation we have:
![4y-x^2=-20\\x^2=4y+20\\-------\\x^2+4y^2=100\\4y+20+4y^2=100](https://tex.z-dn.net/?f=4y-x%5E2%3D-20%5C%5Cx%5E2%3D4y%2B20%5C%5C-------%5C%5Cx%5E2%2B4y%5E2%3D100%5C%5C4y%2B20%2B4y%5E2%3D100)
Now we can solve for y:
![4y+20+4y^2=100\\4y^2+4y-80=0\\y^2+y-20=0\\(y+5)(y-4)=0\\y=4,-5](https://tex.z-dn.net/?f=4y%2B20%2B4y%5E2%3D100%5C%5C4y%5E2%2B4y-80%3D0%5C%5Cy%5E2%2By-20%3D0%5C%5C%28y%2B5%29%28y-4%29%3D0%5C%5Cy%3D4%2C-5)
So plugging in y = 4 into an equation and solving for x, we have:
![x^2=4y+20\\x=+-\sqrt{4y+20} \\x=+-\sqrt{4(4)+20} \\x=+-\sqrt{36} \\x=6,-6](https://tex.z-dn.net/?f=x%5E2%3D4y%2B20%5C%5Cx%3D%2B-%5Csqrt%7B4y%2B20%7D%20%5C%5Cx%3D%2B-%5Csqrt%7B4%284%29%2B20%7D%20%5C%5Cx%3D%2B-%5Csqrt%7B36%7D%20%5C%5Cx%3D6%2C-6)
So y = 4 corresponds to x = 6 & x = -6
The pairs would be
(6,4) & (-6,4)
<u><em>we see that (-6,4) falls in the 2nd quadrant, thus this is the solution we are looking for.</em></u>
If a 1L IV contains 60meq of kcal and the IV was discontinued after 400ml has infused, then the amount of IV received by the patient is 24meq of kcal.
Calculation for the Amount of IV
It is given that,
1L IV contains 60meq of kcal
⇒ 1000 mL of IV contains 60meq of kcal
⇒ 1 mL of IV will contain 60 / 1000 meq of kcal
As per the question,
The amount of IV infused in the patient = 400 mL
⇒ The amount of IV received by the patient in meq of kcal = 400 × (60 / 1000)
= 4 × 6
= 24 meq of kcal
Hence, the patient receives 24meq of kcal amount of IV.
