Answer: 0.939\ or\ 93.9\%

Step-by-step explanation:

Given

Survey shows that 16% of college students have dogs and 38% have HBO subscription

Probability that a random person have both is

\Rightarrow P_o=0.16\times 0.38\quad [\text{As both events are independent}]\\\Rightarrow P_o=0.0608

The probability that the random person has neither of the two is

\Rightarrow P=1-P_o\\\Rightarrow P=1-0.0608\\\Rightarrow P=0.939

Write the equation of the line in slope intercept form that is parallel to y=8x+5 and goes through the point (-2,8)
pychu [463]

Answer:

The equation of the line would be y = 8x + 26

Step-by-step explanation:

In order to find the equation, we first need to note that they will have the same slope due to the definition of parallel lines. Knowing that, we can use the slope and point to find the equation.

y - y1 = m(x - x1)

y - 8 = 8(x + 2)

y - 8 = 8x + 18

y = 8x + 26

A patient has been ordered medication Cat a dosage of 3680 mg/day. The dosage available is 425 mg each scored tablets. • How man
Tema [17]

Answer:

  • about 8 2/3
  • 11 pm

Step-by-step explanation:

The required dosage in terms of tablets is ...

  3680 mg = (3680 mg)/(425 mg/tab) = 8.66 tabs

We don't know how the tablets are "scored", but in my experience they have a groove that facilitates them being cut in half.

We expect the nurse will administer 8 1/2 tablets per day, for a dose of 3613 mg, slightly short of the ordered 3680 mg.

__

9 doses will be administered over 8 time intervals of 2 hours, so will take until 16 hours after 7 am. The last (1/2) dose will be at 0700 +1600 = 2300 hours, or 11 pm.

Drupady [299]

Answer:

7 5/8 lbs. of vegetables.

Step-by-step explanation:

Find a common denominator. 8 4x2 and 2x4 and 8x1. 1/4x2=1/8 and 1/2x4=4/8.

4/8+7/8+2/8=13/8 or 1 5/8.

Add the whole numbers:

3+1+2=6.

Add both sums to get the total:

1 5/8 + 6 = 7 5/8
