2x - 15
R
Р P.
2x - 8
Answers
Answer:
11
Step-by-step explanation:
LK = 1/2RP
theorem: straight line joining the midpoints of two sides of a triangle is parallel to the third side and equal to half the length of the third side.
LK = 2x - 15 ; RP = 2x - 8
2x - 15 = 1/2(2x - 8)
2x - 15 = 2x - 8/2
2x - 15 = x - 4
Collect like terms and simplify
x = 11

In Sahara Desert one day it was 130°F. In the Gobi Desert a temperature of -40°F was recorded. What is the difference between these two temperatures?
Answers
Answer: 170 degree difference
Answer:
The difference between two numbers canbbe obtained substracting.
The diffence between 130 °F and -40 °F would be the same as substracting both numebrs (we should put an absolute value as the difference is positive).
130 - (-40) = 130 + 40 = 170 ° F
So the difference is of 179 °F

What is the volume, in cubic inches, of one cube with an edge length of 1/3 inch
Answers
Answer:
1/27 cubic in.
Step-by-step explanation:
1/3*1/3*1/3= 1/27
The volume of the cube if, its edge length is 1/3 inch is 1 / 27 inches³.
What is volume?The capacity occupied by a three-dimensional solid shape is known as volume. It is difficult to visualize in any shape, yet it may be compared among shapes. For instance, a compass box has a larger volume than an eraser placed inside of it.
Given:
The length of the edge = 1 / 3 inches,
Calculate the volume of the cube as shown below,
The volume of the cube = The length of the edge × The length of the edge × The length of the edge
The volume of the cube = 1 / 3 × 1 / 3 × 1 / 3
The volume of the cube = 1 / 27
Thus, the volume of the cube is 1 / 27 inches³.

Oatmeal is made by mixing 15 cups of hot water to 6 cups of oats.
Answers
9514 1404 393
Answer:
2/5 cups oats per cup water2.5 cups water per cup oatsStep-by-step explanation:
The denominator of the fraction is the unit you want 1 of.
(6 cups oats)/(15 cups water) = (6/15) cups oats/(1 cup water)
= (2/5 cups oats)/(1 cup water)
1 cup of water would need 2/5 cups of oats.
__
Obviously, the other ratio is the reciprocal of this.
(1 cup water)/(2/5 cups oats) = (5/2 cups water)/(1 cup oats)
1 cup of oats would need 2.5 cups of water
Simplify the expression below.

a. Multiply the bottom equation by 6, then subtract the bottom equation from the
top equation.
b. Add the equations.
c. Multiply the top equation by 7, then add the equations.
Answers
Answer:
Step-by-step explanation:h
to eliminate x, multiply the top equation by 7 then add the equations
it is not A because if the bottom equation is multiplied by 6, the y’s will not cancel out if the bottom is subtracted from the top (since 6x - -6x is 12 not 0)
it is not B because adding the equations will not eliminate either variable
doing option C eliminates x since -7x + 7x is 0

In the year 2054 the government estimates that out of every 1,000,100 citizens 1,000,000 will remain law-abiding, and 100 will eventually commit a crime. The government is deciding whether to rely on the clairvoyant Precogs to stop the criminals before they commit the crime. If a person is going to commit a crime, the Precogs identify that person correctly 99.999% of the time (in other words, the Precogs fail to predict crime only in 0.001% of the cases). If a person is not going to commit a crime, the Precogs identify that person as law-abiding 99.99% of the times (in other words, the Precogs convict innocent people only in 0.01% of the cases). What is the probability that a person flagged as a future criminal by the Precogs will actually commit a crime
Answers
Answer:
0.9091 = 90.91% probability that a person flagged as a future criminal by the Precogs will actually commit a crime
Step-by-step explanation:
Bayes Theorem:
Two events, A and B.
[tex]P(B|A) = \frac{P(B)*P(A|B)}{P(A)}[/tex]
In which P(B|A) is the probability of B happening when A has happened and P(A|B) is the probability of A happening when B has happened.
In this question:
Event A: Flagged as future criminal
Event B: Commits a crime.
In the year 2054 the government estimates that out of every 1,000,100 citizens 1,000,000 will remain law-abiding, and 100 will eventually commit a crime.
This means that [tex]P(B) = \frac{100}{1000100} = 0.00009999[/tex]
If a person is going to commit a crime, the Precogs identify that person correctly 99.999% of the time
This means that [tex]P(A|B) = 0.99999[/tex]
Probability of being identified as a criminal:
0.99999 out of 0.00009999(identified and commits crime).
(1-0.99999) out of (1-0.00009999) (identifed and does not commits crime). So
[tex]P(A) = 0.99999*0.00009999 + (1-0.99999)*(1-0.00009999) = 0.000109988[/tex]
What is the probability that a person flagged as a future criminal by the Precogs will actually commit a crime
[tex]P(B|A) = \frac{P(B)*P(A|B)}{P(A)} = \frac{0.00009999*0.99999}{0.000109988} = 0.9091[/tex]
0.9091 = 90.91% probability that a person flagged as a future criminal by the Precogs will actually commit a crime
