serious [3.7K]3 years ago
4 0

Answer:

A,C and D

Step-by-step explanation:

A: 3x2=6

    3x4X=12X

     <em>6+12X</em>

C: 5x1=5

    5x2X=10X

    5+10X+1+2X

   <em>6+12X</em>

D: 7x1=7

    7x2X=14X

     7+14X-2X-1

     6+14X-2X

     <em>6+12X</em>

A person that weighs 179 lbs needs an IV Drip in mL. The drug only comes in powder form but can be converted as 10 mg is equal t
OleMash [197]

Solution:

Weight of person = 179 lbs

As given person needs IV Drip in m L.

Also,→ 10 mg = 2 m L

Now, you must remember , → 1 lbs = 0.453 Kg (approx)

→179 lbs = 179 × 0.453 Kg = 78.47 Kg (approx)

The person needs at least 60 mg for each Kg they weigh.

⇒ 1 Kg → 60 mg

⇒ 78.47 × 1 Kg → 78.47 × 60 mg

⇒ 78.47 Kg →  4708.2 mg

Also, 10 mg → 2 m L

⇒ 1 mg → \frac{1}{5}  m L

⇒ 4708 . 2 mg → \frac{1}{5} \times 4708.2  m L

⇒ 4708 . 2 mg → 941. 64 ml

Ok so basically I dunno all the corr. coefict stuff, but...
in 10 sec it went for 4 to 8, that's doubled
then from 8 to 12 is, +4, 4×3

A. Just during these two intervals we have, y/x: 4/10, then 8/20, then 12/30
0.4, 0.4, 0.4, but then it goes 15/30 = 0.5
so it's not a perfect 100% (1.00) correlation, but it would be very close [I'd choose b) 0.99]

B. from 10-30mins, it went from 4 to 8 to 12
m = change in y ÷ change in x
m = (12-4)/(30-10) = 8/20 = 0.40

C. means that the rate there is 0.40 miles per min. steady, which is 0.40 miles/min × 60min/hr = 24mi/hr steadily without increase or decrease, but a slight decrease from 30-40
RARELY say Causation, Ehr on the side of caution... correlation when in doubt

What is an equation of the line that passes through the points (2, - 1) and (3, - 4)
lianna [129]

Answer:

y=-3x+5

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(-4-(-1))/(3-2)

m=(-4+1)/1

m=-3/1

m=-3

y-y1=m(x-x1)

y-(-1)=-3(x-2)

y+1=-3x+6

y=-3x+6-1

y=-3x+5
