Since the beginning of the year, 1982 people have come into a blood bank to donate blood and 340 were found to have high blood p
Alecsey [184]

Answer:

0.1715

Step-by-step explanation:

From previous experience 340/1982 is the past probability that a person has high blood pressure.

The division of that leads to 0.1715 that the next person will have high blood pressure. That number is roughly (very roughly) 1 person in 6. So if 6 people come in 1 will have high blood presure.

Solve the two step equations
disa [49]

Hello!

1) -3x - 4 = 23

-3x = 23 + 4

-3x = 27

x = 27 : (-3)

x = -9

2) x/2 - 12 = -4

x - 24 = -8

x = -8 + 24

x = 16

3) 6a + (-1) = 10

6a - 1 = 10

6a = 10 + 1

6a = 11

a = 11 : 6

a = 11/6

4) -(x + 2) = 12

x + 2 = -12

x = -12 - 2

x = -14

5) 7a + 12 = 10

7a = 10 - 12

7a = -2

a = -2 : 7

a = -2/7

6) -4(a + 2) = 12

a + 2 = -3

a = -3 - 2

a = -5

Good luck! :)

Edmund purchased a computer for $1,800 on a payment plan (month zero). Three months after he purchased the computer, his balance
trapecia [35]

Answer:

Well I can't make a table but I can explain the answer.

Step-by-step explanation:

So you have $1,800 on a payment plan.  In three months, the balance is 1,350.  So 1,800-1,350=450.  This means he paid $450 in three months.  450/3 is 150.  He pays $150 a month.  Then 2 months later, (5 months after purchase) he has balance is $1,050.  1,350-1,050=300.  300/2=150.  Further evidence of the fact that he pays 150 dollars a month.  This means that the 6th month, he will have $900 dollars left on the payment.  7th month... $850, 8th month... $600, 9th month... $450, 10th month... 300 dollars, 11th month... 150, and 12 month he will have paid off all of his computer.  Hope it helps, sorry it is so long.  Have a great day!  :D
