Answer:
A:-3<x<13
B:-3=<x=<13
C:-3=<x<13
D:-3<x=<13
Step-by-step explanation:
Ok, first lets do A
-3 and -13 and the endpoints and the dots are hollow so its not including
therefore the answer is -3<x<13
next, B
same endpoint this time but both dots are filled in so they are included
therefore: -3=<x=<13
(I'm typing on a keyboard!!! i can't do the fancy symbols lol)
C
same endpoints again but -3 is black and 13 is not
so: -3=<x<13
D
I think you have got the hang of it now probaly
-3 is not filled and 13 is
answer is -3<x=<13
Hope this helps :)

Which condition would prove ΔDEF ∼ ΔJKL?

#CMIIWThe condition that proves congruent of two given triangles ΔDEF ∼ ΔJKL would be option A; DE : JK.
What is the congruent triangle?Two triangles are said to be congruent if the length of the sides is equal, a measure of the angles are equal and they can be superimposed.
we have given proof two triangles congruent by the postulate of SSS.
Since two corresponding sides of these triangles are congruent so additional third side should also be congruent to prove both the triangles congruent.
AC ≅ DF will complete the SSS property to prove both the triangles are congruent.

For which function is the ordered pair (4, 12) not a solution?
1. y = 3 x
2. y = 16 - x
3. y = x + 8
4. y = 8 - x
what’s the answer?
Answers
Answer:
4. y = 8 - x is the right answer
Answer:
4. y = 8 - x
Step-by-step explanation:
The question asks for which function is the ordered pair not a solution?
We need to substitute the ordered pair (4, 12) into x and y.
1. 12 = 3(4) (correct)
2. 12 = 16 - 4 (correct)
3. 12 = 4 + 8 (correct)
4. 12 = 8 - 4 (incorrect)
Therefore, the solution to your question is option 4.

The random variable x is the number of males in the group who have a form of color blindness. Determine whether a probability distribution is given. If a probability distribution is given, find its mean and standard deviation. If a probability distribution is not given, identify the requirements that are not satisfied.

A Yes, the table shows a probability distribution.
B. No, the random variable x's number values are not associated with probabilities.
C. No, not every probability is between O and 1 inclusive.
D. No, the sum of all the probabilities is not equal to 1.
E. No, the random variable x is categorical instead of numerical.
2. Find the mean of the random variable x.

b. the table does not show a probability distribution.
3. Find the standard deviation of the random variable x.
a. infinity = male(s).
b. the table does not show a probability distribution.
Answers
Answer:
1. Yes, the table shows a probability distribution.
2. 0.39 males.
3. 0.6082 males.
Step-by-step explanation:
The random variable x is the number of males in the group who have a form of color blindness. Determine whether a probability distribution is given:
A probability distribution is given if the sum of all probabilities is 1.
We have that:
0.669 + 0.278 + 0.048 + 0.004 + 0.001 + 0 = 1
So yes, the table shows a probability distribution.
2. Find the mean of the random variable x.
We multiply each value by its probability. So
[tex]\mu = 0*0.669 + 1*0.278 + 2*0.048 + 3*0.004 + 4*0.001 + 5*0.000 = 0.39[/tex]
The mean is 0.39 males.
3. Find the standard deviation of the random variable x.
Square root of the subtraction squared of each value and the mean, multiplied by its respective probability. So
[tex]\sigma = \sqrt{0.669*(0-0.39)^2+0.278*(1-0.39)^2+0.048*(2-0.39)^2+0.004*(3-0.39)^2+0.001*(4-0.39)^2+0.000*(5-0.39)^2} = \sqrt{0.3699} = 0.6082[/tex]
The standard deviation is of 0.6082 males.

differentiate y=a/x+b with respect to x, when a and b are constant
Answers
Answer:
-a/(x+b)²
Step-by-step explanation:
Given the function y = a/x+b
To differentiate, we will use the quotient rule.
dy/dx = (Vdu/dx-Udv/dx)/V²
Let u = a
v = x+b
Note that differential of a constant is zero
du/dx = 0
dv/dx = 1
Substitute
dy/dx = (x+b)0 - a (1)/(x+b)²
dy/dx = 0 - a/(x+b)²
dy/dx = -a/(x+b)²
Find t.

calculate the number of terms in the following arithmetic sequence. 6;1;-4;-9....... -239
Answers
Answer:
50
Step-by-step explanation:
Given
first term (a) = 6
Common Difference (d) = 1 - 6 = - 5
Last term (tn )= - 239
Number of terms (n) = ?
We know
Tn = a + ( n - 1 ) d
- 239 = 6 + (n - 1) (-5)
- 239 = 6 - 5n + 5
- 239 = 11 - 5n
5n = 11 + 239
5n = 250
n = 250 / 5
n = 50
The number of terms is 50.

A seamstress charges a $5 fee per garment, plus $15 for each hour of work that the garment requires. The graph below shows the cost of having a single garment fixed by the seamstress, according to the number of hours of work that are needed.
Which linear function models the data?
A. c(t) = 5t
B. c(t) = 15t
C. c(t) = 5 + 15t
D. c(t) = 15 + 5t
Answers
Answer:
C. c(t) = 5 + 15t
Step-by-step explanation:
Well because the initial fee is $5, the answer must have the value of 5 without a variable next to it because this is the y-intercept.
(Only the slope will have the t next to it.)
Because $15 is charged EACH HOUR this would be the slope because there is a constant increase
Therefore c(t) = 5 + 15t
Answer:
C. c(t) = 5 + 15t
Step-by-step explanation:
She charges $15 per hour, so each hour (represented by "t") she earns 15 dollars. She also charges a $5 fee per germent. So she would get $5 plus 15 times however many hours she worked. So your answer would be c(t) = 5 + 15t.
