Calculate the area of the triangle: A =
Answers
Answer:
27
Step-by-step explanation:
The area of the triangle is 30.9 square units.
We have,
From the figure,
Height = Distance between (-2, 6) and (-2, 0).
Base = Distance between (-2, 0) and (7, -5).
To find the distance between two points in a Cartesian coordinate system, use the distance formula:
Distance = [tex]\sqrt{((x_2 - x_1)^2 + (y_2 - y_1)^2)[/tex]
Height:
Distance = √((-2 - (-2))² + (0 - 6)²)
Distance = √(0² + (-6)²)
Distance = √(0 + 36)
Distance = √36
Distance = 6
Base:
Distance = √((7 - (-2))² + (-5 - 0)²)
Distance = √((7 + 2)² + (-5)²)
Distance = √(9² + (-5)²)
Distance = √(81 + 25)
Distance = √106
Distance ≈ 10.3
Now,
The area of the triangle.
= 1/2 x base x height
= 1/2 x 10.3 x 6
= 10.3 x 3
= 30.9 square units
Thus,
The area of the triangle is 30.9 square units.

To find the perimeter of a shape, you need to add the length of the 4 sides. A square's 4 sides are equal. Therefore, you add n+n+n+n which is the same as 4n.
Answer:
P = n4
Step-by-step explanation:
in order to find the perimeter of an object you must add up all the sides. since we are dealing with a square all the sides are n. so in conclusion, 4 times n would you get you the perimeter, P.

What is the greatest perfect square that is a factor of 392
Answers
Answer:
The factor of 392 is 36.
The greatest perfect square that is a factor of 392 is 14.
Given,
392
We need to find the greatest perfect square which is a factor of 392.
What is a factor of a number?Example:
2 x 4 = 6
2 and 4 are factors of 6.
Find the factor of 392.
Possible factors are:
4 x 98 = 392
49 x 8 = 392
196 x 2 = 392
We see that,
4, 196, and 49 are perfect squares.
2 x 2 = 4
14 x 14 = 196
7 x 7 = 49
14 is the greatest perfect square.

In a certain community, 8% of all adults over 50 have diabetes. If a health service in this community correctly diagnoses 95% of all persons with diabetes as having the disease and incorrectly diagnoses 2% of all persons without diabetes as having the disease, find the probabilities that
a) the community health service will diagnose an adult over 50 as having diabetes.
b) a person over 50 diagnosed by the health service as having diabetes actually has the disease.
Answers
Answer and Step-by-step explanation:
Solution:
Given:
Let A is the event of a person over 50 diagnosed by health service.
B1 is the event that an adult over 50 actually has diabetes.
B2 is the event that an adult over 50 does not have diabetes.
P (B1) = 8% = 0.08
And P (B2) = 1 – P (B1)
= 1 – 0.08
= 0.92
Correctly diagnose of all persons with diabetes= 95%
P (A/B1) = 0.95
Incorrectly diagnose of all persons without diabetes= 2%
P (A/B2) = 0.02
(a) ) the community health service will diagnose an adult over 50 as having diabetes.
P (B1) P (A/B1) = (0.08) (0.95) = 0.076
P (B2) p (A/B2) = (0.92) (0.02) =0.0184
P (B1) P (A/B1) + P (B2) p (A/B2) = 0.076 + 0.0184
= 0.0944
(b) A person over 50 diagnosed by the health service as having diabetes actually has the disease.
By using formula:
P (B1/A) = P (B1) P (A/B1) / P (B1) P(A/B1) + P (B2) P (A/B2)
Put all the given values:
= (0.08) (0.95) / (0.08) (0.95) + (0.92) (0.02)
=0.076 / 0.076 + 0.0184
=0.076 / 0.0944
= 0.8050
Using conditional probability, it is found that there is a:
a) 0.0944 = 9.44% probability that the community health service will diagnose an adult over 50 as having diabetes.
b) 0.8051 = 80.51% probability that a person over 50 diagnosed by the health service as having diabetes actually has the disease.
Conditional Probability
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]
In which
P(B|A) is the probability of event B happening, given that A happened. [tex]P(A \cap B)[/tex] is the probability of both A and B happening. P(A) is the probability of A happening.Item a:
The percentages of a positive test is:
95% of 8%(have diabetes).2% of 92%(do not have diabetes).Hence:
[tex]P(A) = 0.95(0.08) + 0.02(0.92) = 0.0944[/tex]
0.0944 = 9.44% probability that the community health service will diagnose an adult over 50 as having diabetes.
Item b:
Event A: Positive test.Event B: Has the disease.From item a, [tex]P(A) = 0.0944[/tex].
The probability of both a positive test and having the disease is:
[tex]P(A \cap B) = 0.95(0.08)[/tex]
Hence, the conditional probability is:
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.95(0.08)}{0.0944} = 0.8051[/tex]
0.8051 = 80.51% probability that a person over 50 diagnosed by the health service as having diabetes actually has the disease.

Answers
Answer:
1) x = 3/2 2) x = 6 3) x = 3
Step-by-step explanation:
For Number 1:
4(x+8)−4=34
Step 1: Simplify both sides of the equation.
4(x+8)−4=34
(4)(x)+(4)(8)+−4=34(Distribute)
4x+32+−4=34
(4x)+(32+−4)=34(Combine Like Terms)
4x+28=34
Step 2: Subtract 28 from both sides.
4x=6
Step 3: Divide both sides by 4.
4x/4 = 6/4
x = 3/2
For Number 2:
2/3(9+x)=−5(4−x)
Step 1: Simplify both sides of the equation.
6 + 2/3x = −20+5x
Step 2: Subtract 5x from both sides.
−13 /3 x+6=−20
Step 3: Subtract 6 from both sides.
-13/3x = -26
Step 4: Multiply both sides by 3/(-13)
x = 6
For Number 3:
−3(x+4)+15=6−4x
Step 1: Simplify both sides of the equation.
−3(x+4)+15=6−4x
(−3)(x)+(−3)(4)+15=6+−4x(Distribute)
−3x+−12+15=6+−4x
(−3x)+(−12+15)=−4x+6(Combine Like Terms)
−3x+3=−4x+6
−3x+3=−4x+6
Step 2: Add 4x to both sides.
−3x+3+4x=−4x+6+4x
x+3=6
Step 3: Subtract 3 from both sides.
x+3−3=6−3
x = 3

Answers
Answer:

Step-by-step explanation:
collect the x stuff on one side
2/3 x + 1/6 x = 9 + 1
5/6 x = 10
x = 12
Answer:
x=12
Step-by-step explanation:
first, you need to get the variable to one side
the easiest way to do it and not deal with negatives would be this way:
2/3x - 1 = 9 - 1/6x
+1/6x +1/6x in order to do this you must first convert the 2/3 to 4/6
to then get
5/6x - 1 = 9
then solve it like normal
5/6x - 1 = 9
+1 +1
5/6x = 10
/ 5/6 /5/6
x=12
Solve the system of linear equations by graphing y = -4x + 2 ; y = -x - 1
What is the solution?
Answers
Answer:
Step-by-step explanation:
Easiest way would be to substitute points into the given equations and plot your answers.
E.g. if you substitute points into your first equation you get:
If x = 0, y = -4(0) +2 = 2
If x = 1, y = -4(1) +2 = -2
If x = -1, y = -4(-1) +2 = 6
Etc.
Second equation:
If x = 0, y= -(0) -1 = -1
If x = 1, y = -1 -1 = -2
If x = -1, y = -(-1) -1 = 0
Pretty much just plug in values for x into the equations to find y.
Once you have your points, draw a line :)
Where the two lines intercept would be the solution.

The only zero of the equation 0=18c³−50c is c = 0, as it makes the equation true when substituted.
value is a zero of the equation 0 = 18c³ - 50c,
putting in the value for c
If c = 0:
0 = 18(0)³ - 50(0)
0 = 0 - 0
0 = 0 (True)
If c = 2:
0 = 18(2)³ - 50(2)
0 = 18(8) - 100
0 = 144 - 100
0 = 44 (False)
If c = -1:
0 = 18(-1)³ - 50(-1)
0 = 18(-1) + 50
0 = -18 + 50
0 = 32 (False)
only c = 0 is a zero of the equation 0 = 18c³ - 50c.
The equation 0 = 18c³ - 50c has only one zero, which is c = 0, as it satisfies the equation when substituted.

ABC was translated Find A
Answers
Answer:
A' (2, -1)
Explanation:
The object's point A has a coordinate of (-2, 4).
The translation rule states that you:
- Add the x coordinate by 4 (x + 4)
- Subtract the y coordinate by 5 (y - 5)
Substitute the rule to point A's coordinate (x = -2 and y = 4).
(-2 + 4 , 4 - 5) = (2, -1)
Notice that the image's point A has moved four steps to the right and down by five steps from the original object.
