Using the point-slope form:
⇒ [tex](y-y0) = m(x-x0)[/tex]
Which require one point (x0,y0) on the line and the slope (m)
(x0,y0) --> (-4,-2)m --> 0Thus let us plug int the value
[tex](y + 2) = 0(x + 4)\\y + 2 = 0\\y = -2[/tex]
Thus the equation of the line is y = -2

A test has been developed to detect a particular type of arthritis in individuals over 50 years old. From a national survey it is known that approximately 10% of the individuals in this age group suffer from this form of arthritis. The proposed test was given to individuals with confirmed arthritics disease, and a correct test result was obtained in 85% of the cases. When the test was administered to individuals of the same age group who were known to be free of the disease, 4% were reported to have the disease. What is the probability that an individual has this disease given that the test indicates its presence
Answer:
The probability that an individual has this disease given that the test indicates its presence is 0.1
Step-by-step explanation:
Let A be the event which indicates Having disease
Let B be the event in which test indicates that disease presence
Now we are given that 10% of the individuals in this age group suffer from this form of arthritis
So, P(A)=0.1
We are also given that the proposed test was given to individuals with confirmed arthritics disease, and a correct test result was obtained in 85% of the cases.
P(B|A)=0.85
Now we are given that. When the test was administered to individuals of the same age group who were known to be free of the disease, 4% were reported to have the disease
So,P(B|A')=0.04
We are supposed to find the probability that an individual has this disease given that the test indicates its presence i.e. P(A|B)
So we will use Bayes theorem
[tex]P(A|B)=\frac{P(B|A) P(A)}{\sum P(B|A) P(A)}[/tex]
[tex]P(A|B)=\frac{0.85 \times 0.1}{0.85 \times 0.1+0.85 \times 0.9}=0.1[/tex]
Hence the probability that an individual has this disease given that the test indicates its presence is 0.1
plot the x intercepts,maxima and minima of y=cos(x) from 0 to 2pi
Answer:
Figure of the function is included below as attachment.
Step-by-step explanation:
Let [tex]y = \cos x[/tex]As first step we have to find x intercepts, maxima and minima from 0 to 2π, which are needed to plot given function. Cosine is a trigonometric function bounded between -1 and 1 with a periodicity of 2π.
x-Intercepts
x-intercepts are those points of the function such that [tex]y = 0[/tex]. That is:
[tex]\cos x = 0[/tex]
In this case, there is a periodicity of π for [tex]y = 0[/tex]. The x-intercepts are in the following set:
[tex]S = \{\forall\,x\in\mathbb{R}|x=0.5\pi\pm\pi\cdot i,i\in\mathbb{N}_{O} \}[/tex]
Maxima
Maxima are those points of the function such that [tex]y = 1[/tex]. That is:
[tex]\cos x = 1[/tex]
In this case, there is a periodicity of 2π for [tex]y = 1[/tex]. Maxima are in the following set:
[tex]S = \{\forall\,x\in\mathbb{R}|x=0\pm2\pi\cdot i,i\in\mathbb{N}_{O} \}[/tex]
Minima
Minima are those points of the function such that [tex]y = -1[/tex]. That is:
[tex]\cos x = -1[/tex]
In this case, there is a periodicity of 2π for [tex]y = -1[/tex]. Minima are in the following set:
[tex]S = \{\forall\,x\in\mathbb{R}|x=\pi\pm2\pi\cdot i,i\in\mathbb{N}_{O} \}[/tex]
Lastly, we proceed to plot the function as well as its x-intercepts, maxima and minima with the help of a plotting tool.

5x – 3y = 15? Write your answer as an ordered
pair.
Answer:
(0, -5)
Step-by-step explanation:
For Y-intercept: put X = 0
5x-3y=15
-3y=15-5x
3y=-15+5x
y=-5+5/3x
y=5/3x-5

Please help it's due today!!!!!!
Answer:
See Below
Step-by-step explanation:
We are given 3 equations.
3x + 8
5x - 20
and
5x + 4y
First lets solve for x using the first two
3x + 8 = 5x -20
Move the variables to one side
3x + 8 = 5x -20
-3x -3x
8 = 2x -20
+20 +20
28 =2x
28/2 =2x /2
14 = x
Now we have x = 14
Lets plug this into the second equation to solve for the angle
3(14) + 8
42 + 8 = 50
5(14) - 20
70 - 20 =50
Now, lets plug the x and the angle into the third equation to find y
5 (14) +4y = 50
70 + 4y = 50
-70 -70
4y = -20
4y/4 = -20/4
y = -5
So now we have:
x = 14
y = -5
and the angle = 50

The measures of two vertical angles are 29° and (2x + 3)º. Find the value of x .
Answer:
Vertical Angles!
Step-by-step explanation:
Very simple!
Vertical angles are a pair of angles that are equal in degree measure.
Essentially, they are equal to each other. Nothing more to it.
This means that [tex]29=2x+3[/tex]!
I presume you have done math before, so this solves to be: [tex]x=13[/tex]
(I don't have a degree sign, but it should be there in your answer.)

If a seed is planted, it has a 95% chance of growing into a healthy plant. If 10 seeds are planted, what is the probability that exactly 2 don't grow?
Answer:
The probability that exactly 2 don't grow is 0.075 or 7.5%
Step-by-step explanation:
Binomial Distribution
Let's consider a random experience with only two possible outcomes. Call p to the probability that the event has a successful outcome and q to the unsuccessful outcome.
It's clear that p+q=1, or q=1-p.
Now repeat the random experience n times. We want to calculate the probability of getting x successful outcomes. This can be done with the following formula:
[tex]\displaystyle P_{x} = {n \choose x} p^{x} q^{n-x}[/tex]
Where
[tex]\displaystyle {n \choose x}[/tex]
Is the number of combinations:
[tex]\displaystyle {n \choose x} =_nC_x=\frac{n !}{x ! (n-x) !}[/tex]
For the problem to solve, each seed has a p=0.95 probability of growing into a healthy plant. The value of q=1-0.95=0.05.
The experience is repeated n=10 times and we want to estimate the probability that 2 of them don't grow. Note this last data is not directly the value of x because it's not related to success but with no success. The value of x is x=10-2=8. That means, 8 out of 10 seeds grow.
Apply the formula:
[tex]\displaystyle P_{8} = {10 \choose 8} \cdot 0.95^{8} \cdot 0.05^{10-8}[/tex]
[tex]\displaystyle P_{8} = 45\cdot 0.95^{8} 0.05^{2}[/tex]
[tex]\displaystyle P_{8} = 0.075[/tex]
The probability that exactly 2 don't grow is 0.075 or 7.5%

Rectangle a measures 9 inches by 3 inches. Rectangle b is a scaled copy of rectangle a .select a set of measurement pairs that could be the dimensions of of rectangle b
Answer:
Dimensions of Rectangle B will be 9x inches by 3x inches where x is a scaling factor.
Step-by-step explanation:
Scaled Copy: It means that the rectangle A is related to rectangle B by some scaling (multiplying) factor x.
As we are given Dimensions of rectangle A = 9 inches by 3 inches
Then for any scaling factor x the dimensions of rectangle B will be:
Dimensions of Rectangle B = x * ( Dimensions of rectangle A)
Dimension of rectangle B = x * (9 inches by 3 inches)
Dimensions of rectangle B = 9x inches by 3x inches
For more understanding let we assume that rectangle B is scaled copy of rectangle A by scaling factor x=3; then we will have the dimensions of rectangle B as under:
For scaling factor (x) = 3;
Dimensions of Rectangle B = x * ( Dimensions of rectangle A)
Dimensions of rectangle B = 3 (9 inches by 3 inches)
Dimensions of rectangle B = 27 inches by 9 inches
On the other hand for scaling factor x=0.75, the dimensions of rectangle B will become as under;
Dimensions of Rectangle B = x * ( Dimensions of rectangle A)
Dimensions of rectangle B = 0.75 (9 inches by 3 inches)
Dimensions of rectangle B = 6.75 inches by 2.25 inches
Your grandma pays upfront for you to go on an overnight trip with the school, which costs $340. You make a deal that you’ll give her $25 per month until you pay it all back. How will you pay Grandma?
Answer:
350
Step-by-step explanation:
pretty easy just dived
You pay $350 to Grandma.
What is Multiplication?
To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
Grandma pays upfront for you to go on an overnight trip with the school, which costs $340.
And, You make a deal that you’ll give her $25 per month until you pay it all back.
Now,
Let the number of months to pay Granma = x
Then, we can formulate;
$25x = $340
x = 13.6
After rounding,
x = 14
So, We pay 14 months to grandma;
Hence, The cost to pay grandma in 14 months = 14 x $25
= $350
Therefore, You pay $350 to Grandma.
