On a hospital floor, 16 patients have a disease with a mortality rate of 0.1. Find the probability that two of them die. Round to three decimal places
Answer:
The probability that two of them
die is 0.257
Step-by-step explanation:
From the question, we have that the mortality rate is 0.1
So the probability that they will survive is 1-0.1 = 0.9
Now, we want to check that two will die
We are going you use the Bernoulli approximation of the Binomial theorem as follows
= nCr * p^n * q^(n-r)
where n = 16
r = 2
P = 0.1
q = 0.9
Substituting these values;
14 C 2 * 0.1^2 * 0.9^12
= 0.257

Answer:
what? im confused
Step-by-step explanation:
Answer:
A protractor is a tool used to measure angles in degree. There are two basic types of protractors. One that measures 180º (half a circle). One that measures 360º (a full circle).

Answer: $800 because if you have a light that is $2,000 and it loses %10 of its price per month, and June is 4 months away, then it is only $800.
4 x .1 = .4 so $2,000 x .4 = $800
(50 POINTS) Composite Functions MATH please help
Answer:
a. C(x(h)) = 600h + 500
b. C(8) = 5,300
c. See below.
Step-by-step explanation:
a. C(x(h)) = C(30h) = 20(30h) + 500 = 600h + 500
b. C(8) = 600(8) + 500 = 5,300
c. 5,300 is the cost of making the number of shovels that can be made in 8 hours.

Answer:
x = 58°
Step-by-step explanation:
ABCD is a cyclic quadrilateral and opposite angles are supplementary , so
∠ DAB = 180° - 121° = 59°
The angle between a tangent and a chord is equal to the angle in the alternate segment, then
∠ ABD = 63° , thus
x = 180° - (59 + 63)° = 180° - 122° = 58°
The histogram shows the ages of people in a community chorus. How many people in the chorus are 50 or older? Enter your answer in the box.
Answer:
13
Step-by-step explanation:
The computation of the number of people in the chorus are 50 or older is as follows
According to the attached figure
In the age of 50 - 60 , there is 8 people
In the age of 60 - 70 , there is 4 people
In the age of 70 -80, there is 1 people
So, if we do the total that comes
= 8 people + 4 people + 1 people
= 13 people
Hence, the no of people would be 13

in the diagram,the measure of angle ACB is 25 degrees. what is the measure of angle AOB?
Answer:
m<AOB = 50°
Step-by-step explanation:
<ACB = 25° is an inscribed angle of the circle.
<AOB is a central angle of the circle.
Thus, based on the inscribed angle theorem which states that an inscribed angle is ½ the measure of the central angle, therefore:
m<ACB = ½(m<AOB)
Substitute
25° = ½(m<AOB)
Multiply both sides by 2
2*25 = m<AOB
m<AOB = 50°
A triangle has angles measuring 35° and 90°. What is the measure of the third angle?
Answer:
55 degrees
Step-by-step explanation:
All the angles of a triangle should add up to 180 degrees.
So, if you add angles 1 and 2 together and subtract them from 180 it will result in the unknown angle.
35+ 90 + x = 180
125 + x = 180
x = 55

6. How far is it from the point (-5, 7) to the point (6,-2)? Round your answer to the nearest tenth.
Answer:
14.2 units
Step-by-step explanation:
Here x increases by 11 from -5 to +6. This is the length of the horizontal leg of a right triangle. Then y decreases by 9 from 7 to -2. This is the length of the vertical leg. The hypotenuse of this triangle may be found using the Pythagorean Theorem:
11^2 + 9^2 = (hypotenuse)^2, or
hypotenuse = √(121 + 81) = √202 ≈ 14.2 units
Answer:
≈ 14.2
Step-by-step explanation:
Calculate the distance d using the distance formula
d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]
with (x₁, y₁ ) = (- 5, 7) and (x₂, y₂ ) = (6, - 2)
d = [tex]\sqrt{(6+5)^2+(-2-7)^2}[/tex]
= [tex]\sqrt{11^2+(-9)^2}[/tex]
= [tex]\sqrt{121+81}[/tex]
= [tex]\sqrt{202}[/tex]
≈ 14.2 ( to the nearest tenth )

-5 = 1/7a
Answer:
-35
Step-by-step explanation:
[tex]-5 = \frac{1}{7}a\\-35 = a[/tex]
I got this by multiplying the numerator by 7. This allows the denominator to be the same as the numerator, thus equalling 1.
1 * a = a
Answer: a = -35
Step-by-step explanation:
1. -5 = 1/7(a) || GIVEN
2. -5 * (7) = (7) * 1/7(a) || Isolate "a" on one side of the equation by multiplying 7 to the other side.
3. -35 = a

In if GS ⊥ XJ and XJ⊥EA what is true about GS and EA
Answer:
([tex]GS[/tex]) || ([tex]EA[/tex])
Step-by-step explanation:
When two lines are parallel, all four angles formed by the intersection of the two lines are right angles, meaning their angle measures are (90°). This means that alternate interior angles are congruent because all alternate interior angles measures equal (90°). Therefore, by the alternate interior angles converse theorem, lines ([tex]GS[/tex]) and ([tex]EA[/tex]) are parallel.
The alternate interior angles converse theorem states if two angles are congruent and they have the relation of being a part of two lines intersected by a third line, then the two non-intersecting lines are parallel.
