1. Suppose that 35% of all patients admitted to a hospital's intensive care unit (ICU) have high blood pressure, 42% have some sort of infection, and 12% have both problems
Answer:
a) 65%
b) 28.57%
Step-by-step explanation:
Suppose that 35% of all patients admitted to a hospital's
intensive care unit have high blood pressure, 42% have some sort of infection, and 12% have both problems. Probabilities estimated from the data in ICU Admissions. (10POINTS)
(a) Find the probability that a randomly chosen patient in this ICU has either high blood pressure or an infection.
(b) Find the probability that a patient admitted to the ICU has high blood pressure given that an infection is present.
Solution:
Let H represent the people with high blood pressure and I represent the people with infection.
P(H) = 35% = 0.35, P(I) = 42% = 0.42, P(H ∩ I) = 12% = 0.12
Those with only high blood pressure = P(H ∩ I') = P(H) - P(H ∩ I) = 0.35 - 0.12 =0.23
Those with only infection = P(H' ∩ I) = P(I) - P(H ∩ I) = 0.42 - 0.12 =0.30
a) probability that a patient has either high blood pressure or an infection = P(H ∪ I)
P(H ∪ I) = P(H ∩ I') + P(H' ∩ I) + P(H ∩ I) = 0.23 + 0.3 + 0.12 = 0.65 = 65%
b) probability that a patient has high blood pressure given that an infection is present = P(H / I)
P(H / I) = P(H ∩ I) / P(I) = 0.12 / 0.42 = 0.2857 = 28.57%

Which of the following equations is equivalent to y-3 = -2(x-6)?
а. y=-5x-9
b. y = -2x 3
с. y= -5x - 15
d. y = -2x + 9
Answer:
Step-by-step explanation:
Which of the following equations is equivalent to y-3=-2(x-6): y+3x=6 ... Move the +3*x to the right side by subtracting 3*x from (or adding negative 3*x to) ... And in addition, we know that the line graph crosses the y-axis where y equals y=-2x3.
Given the following equation, solve for the easiest variable.
3x + y = -6
Answer:
Let's solve for x.
3x+y=−6
Step 1: Add -y to both sides.
3x + y + −y = −6 + −y
3x = − y − 6
Step 2: Divide both sides by 3.
3x / 3 = − y −6 / 3
x = − 1 / 3 y −2
Answer:
x = − 1 / 3 y −2

three odd consecutive integers are such that 3 times the smallest is 9 more than twice the largest .find the three numbers
Answer: 17, 19, 21
Step-by-step explanation:
Three consecutive odd numbers: x, x+2, x+4 (since odd numbers occur every other number)
Just to show you that the numbers are x, x+2, and x+4, just say x is 13 then x+2 is 15 and x+4 is 17 (3 consecutive odd numbers)
Now the second equation:
3x = 2(x+4) + 9
three times smallest number (which is x) is equal to 2 times the largest number (x+4) plus 9
Now solve
3x = 2(x+4) +9
3x = 2x + 8 + 9
3x = 2x + 17
x = 17
x+2 = 19
x+3 = 21
Express the polynomial as a product of linear factors.
f(x) = 2x2 + 4x2 - 2x - 4
O A. (x-2)(x + 1)(x - 1)
O B. (x-2)(x-2)(x-1)
O c. 2(x + 2)(x + 1)(x-1)
O D. (x-4)(x + 1)(x-1)
The polynomial f(x) = 2x³ + 4x² - 2x - 4 can be expressed as a product of linear factors as (x + 2)2(x - 1)(x + 1)
We have,
To express the polynomial f(x) = 2x³ + 4x² - 2x - 4 as a product of linear factors, we can use a technique called factorization by grouping.
First, let's group the first two terms and the last two terms together:
f(x) = (2x³ + 4x²) + (-2x - 4)
Factor out the greatest common factor from each group:
f(x) = 2x²(x + 2) - 2(x + 2)
Notice that we now have a common factor of (x + 2) in both terms.
We can factor it out:
f(x) = (x + 2)(2x² - 2)
Now we can factor the quadratic expression 2x^2 - 2 by factoring out the greatest common factor of 2:
f(x) = (x + 2)2(x² - 1)
Now we can factor the expression x² - 1 as the difference of squares:
f(x) = (x + 2)2(x - 1)(x + 1)
Therefore,
The polynomial f(x) = 2x³ + 4x² - 2x - 4 can be expressed as a product of linear factors as (x + 2)2(x - 1)(x + 1)

Answer:
JM = 20
Step-by-step explanation:
Find the value of JM
Using similar triangles;
MJ/HN = GJ/HK
GJ+JM/HN = GJ/HK
15+JM/12+16 = 15/12
15+JM/28 = 15/12
Cross multiply
12(15+JM) = 15*28
180+12JM = 420
12JM = 420 - 180
12JM = 240
JM = 240/12
JM = 20
Hence the length of JM is 20

The ages of the racers in a bicycle motocross race are 14, 22, 20, 25, 26, 17, 21, 30, 27, 25, 14, and 29. The 30-year-old drops out of the race and is replaced with a 15-year-old. How are the mean, median, and mode of the ages affected?
Answer:
The mean is decreased by 1.25.
The mode remains the same.
The median is decreased by 2 .
Step-by-step explanation:
Re arranging the data 14, 22, 20, 25, 26, 17, 21, 30, 27, 25, 14, and 29.
Gives
14, 14,17,20, 21, 22, 25,25, 26, 27, 29,30,
Now the mean = 14, +14,+17, +20, +21,+ 22, +25,+25,+ 26, + 27, +29,+30/12
Mean= 270/12=22.5
The Mode ( the repeated value) = 14,25
Median ( the average of middle value) = 22+25/2= 23.5
When 30 is replaced is by 15
Now the mean = 14, +14, +15,+17, +20, +21,+ 22, +25,+25,+ 26, + 27, +29/12
The Mean becomes = 255/12=21.25
The Mode ( the repeated value) = 14,25
Median ( the average of the middle value) = 21+22/2= 21.5
The difference between the 2 means is = 22.5- 21.25= 1.25
The mode remains the same.
The median is decreased by 2 .
The mean is decreased by 1.25 which is more than 50 % of the value obtained between the ratio of the omitted and added value (30/15=) i.e. 2
