People with O-negative blood are universal donors. That is, any patient can receive a transfusion of O-negative blood. If three people randomly arrive to donate blood at a blood drive, what is the probability that at least one of them is a universal donor?
Answer:
Probability of at least 1 out of 3 being O-negative = 20.1%
Note: The question is incomplete. A similar question is given below:
People with type O-negative blood are universal donors. That is, any patient can receive a transfusion of O-negative blood. Only 7.2% of the American population have O-negative blood. If we choose 10 Americans at random who gave blood, what is the probability that at least 1 of them is a universal donor?
Step-by-step explanation:
Probability of O-negative blood in the population = 7.2% or 0.072
Probability of not being O-negative = 1 - P(O-negative) = 1 - 0.072 = 0.928
Using the multiplication rule to determine the probability of 10 people not being O-negative
Probability of 10 not negative = (P(not O-negative)¹⁰ = (0.928)¹⁰ = 0.4737
Hence, probability of at least 1 being O-negative = 1 - P(not O-negative) = 1 - 0.4737 = 0.5263
In percentage, P(at least 1 out of ten being O-negative) = 52.63%
Given 3 random donors
Probability of 3 not negative = (P(not O-negative)³ = (0.928)³ = 0.7991
Hence, probability of at least 1 being O-negative = 1 - P(3 not O-negative) = 1 - 0.7991 = 0.2009
In percentage, P(at least 1 out of 3 being O-negative) = 20.1%
Identify the graph of the point G(0, −1, −3) in three-dimensional space.
Answer:
In 3 dimensions, we use the notation for points (x, y, z)
Then the point:
(0, -1, -3)
has:
x = 0
y = -1
z = -3
In a 3 dimensional space, the rectangular coordinates are as follows.
The one that goes up is Z
The one that goes to the right is X.
The one that "comes out" or is normal to the page, is Y.
Below you can see the point in a 3D-space:
Where: Blue = Z
Green = Y
Red = X
Kim and Cyndi are starting a business tutoring students in math. Kim rents an office for $350 per month and charges $20 per student. Cyndi rents an office for $400 per month and charges $15 per student. How many students do they have to teach per month in order to make the same amount of money?
Answer:
10 studentsStep-by-step explanation:
Kims Charges
rent per month =$350
charges=$20 per students
let the number of students be x
and the total be y
y=mx+c
y=20x+350--------------------1
Cyndis Charges
rent per month =$400
charges=$15 per students
let the number of students be x
and the total be y
y=mx+c
y=15x+400-------------------2
Equating the two equations above to solve for x
20x+350=15x+400
20x-15x=400-350
5x=50
x=50/5
x=10
The number of students is 10 for the two of them to have the same amount

(2)
[tex]\sqrt[10]{x^{12} }[/tex] = [tex]x^{\frac{12}{10} }[/tex] ← exponent is not an integer
(3)
[tex]\sqrt[12]{x^{18} }[/tex] = [tex]x^{\frac{18}{12} }[/tex] ← exponent is not an integer

Joe bought a box of laundry detergent that contains 195 scoops. Each load of laundry uses 2.5 scoops. How many loads of laundry can he do with this one box? The box of detergent was $19.99. How much is he paying for each load that he washes? Round to the nearest hundredths place.
Answer:
-Joe can do 78 loads of laundry with this one box.
-He is paying $0.25 for each load that he washes.
Step-by-step explanation:
To determine the number of loads of laundry that Joe can do with this one box, you have to divide the total amount of scoops in a box by the amount of scoops that each load of laundry uses:
195/2.5=78
This means that Joe can do 78 loads of laundry with this one box.
Now, to find the amount that he is paying for each load that he washes, you have to divide the cost of the box of detergent by the amount of loads of laundry you can do with one box:
19.99/78=0.25
According to this, he is paying $0.25 for each load that he washes.

How do I solve tan(60)=6/x
Answer:
3.5
Step-by-step explanation:
tan60=6/x
cross multiply
tan60x=6
1.732x=6
divide both sides by 1.732
1.732x/1.732=6/1.732
x=3.464 approximately 3.5
Answer:
tan(60)=6/x
tan(60)=6/x,x ≠ 0
tan(60)×x=6
x 6/tan(60) , x ≠ 0
x= 6/tan(60)

Using the formula for circumference, =×, choose the answer that most accurately represents the circumference of the circle. Use 3.14 for pi. 5.6 cm 5.652 cm 5.7 cm 5.65 cm __________________________ 1.8 cm
Answer:
Step-by-step explanation:
Circumference of a circle = πd
d is the diameter of the circle
Let us assume the diameter to be 1.8cm
Substitute into the formula;
C = 1.8π
C = 1.8(3.14)
C = 5.652 cm
Hence the circumference of the circle is 5.652cm

What is the relationship between the slopes of two perpendicular lines?
relation between two slopes of two perpendicular line are equal.
The relationship between the slopes of two perpendicular lines is that the product of the slopes of the two lines is equal to -1.
What are perpendicular lines?Two geometric objects are perpendicular in elementary geometry if they intersect at a right angle. When two lines cross at a straight angle, they are said to be perpendicular.
The relationship between the slopes of two perpendicular lines is that the product of the slopes of the two lines is equal to -1. Therefore, assuming that there are two lines that are perpendicular to each other such that the slope of the two lines is m₁ and m₂. Therefore, we can write the relation as,
m₁ × m₂ = -1
Hence, the relationship between the slopes of two perpendicular lines is that the product of the slopes of the two lines is equal to -1.

The wheels on Noah's bike have a circumference of about 5 feet. About how long is a spoke on the bike wheel that goes from the center to the rim of the wheel? Round to the nearest tenth.
Answer:
0.8ft
Step-by-step explanation:
Given the circumference, we want find the diameter, and the radius is the length of the spoke
the expression for circumference is
C=2πr
given
C=5feet
5=2*3.142*r
5=6.284r
Divide both sides by 6.284 we have
5/6.284=r
r= 0.795 ft
to the nearest tenth this is 0.8ft

(4x^3 y^7)^3
=12x^9 y^21
Answer:
4 was multiplied by 3; instead the 4 should've been raised by the power of 3.
Step-by-step explanation:
For my analysis I am assuming that the exponent on the first figure is only on the variable.
(4x^3 y^7)^3
Distribute the exponent on the parentheses to all exponents inside of the parenthesis.
((4^3) ((x^3)^3) ((y^7)^3))
64(x^9)(y^21)
The error in the problem therefore, is that 4 was multiplied by 3 instead of raised by the power of 3 (4(4)(4)).
