Find the value of n so that the line perpendicular to y = (-1/3)X-4 passes through the points (n. 6) and (4,15).

iogann1982 [59]

Answer:

Step-by-step explanation:

The slope of the perpendicular is the negative inverse of the slope of the line.

m = -1 / (-⅓)

m = 3

The slope between the two points is 3, so:

3 = (15 − 6) / (4 − n)

3 (4 − n) = 9

4 − n = 3

n = 1

The 5th term in a geometric sequence is 162. The 2nd term is 6, The sum of the 1st 5 terms is.

NISA [10]

Answer:

Step-by-step explanation:

t2 = a*r

t2 = 6

t5 = a*r^4

t5 = 162

162/6 = ar^4 / ar

r^3 = 27

r = 3

6 = a*3

2 = a

Sum = a(r^n - 1)

=======

r - 1

n = 5

a = 2

r = 3

Sum = 2(3^5 - 1)

=======

Sum = 242

A game involves rolling a number cube. You get one point if you roll an even number and negative one point if you roll an odd nu

Burka [1]

Answer: The sample space is {1, 2, 3, 4, 5, 6}.

The expected value for the game is 0.

The game is fair because the expected value is equal to 0.

Step-by-step explanation:

For rolling a dice the sample space = {1, 2, 3, 4, 5, 6}

As there are equal number of odd numbers as well as even numbers and we get one point if we roll an even number and negative one point if you roll an odd number, therefore, the expected value = 0

Therefore, the game is fair because the expected value is equal to 0.

Bud's cheeseburger and fries contained 1310 milligrams and 350 milligrams of sodium, respectively. Together they contained 66.4%

Serhud [2]

Answer:

The recommended daily intake of sodium for a 2000 calorie diet is 2500 mg.

Step-by-step explanation:

In order to calculate the daily intake of sodium we first need to calculate the mass of sodium present in both snacks, this is given by their sum.

$\text{total sodium} = 1310 + 350 = 1660 \text{ mg}$

We can now apply a rule of three for which the total sodium from the snacks is related to 66.4% in the same proportion as "x" mg, which is the value we want to know, is related to 100%. So we have:

$\frac{1660}{x} \frac{mg}{mg} = \frac{66.4\%}{100\%}$

$66.4*x = 1660*100\\x = \frac{166000}{66.4} = 2500 \text{ mg}$

The recommended daily intake of sodium for a 2000 calorie diet is 2500 mg.
