Answer:
x = 10.2
Step-by-step explanation:
Formula:
a² + b² = c²
16² + b² = 19²
256 + b² = 361
b² = 361 - 256
b² = 105
b = 10.2

2) 85° = (3x - 5)° [Vertically Opposite Angles]
=> 3x - 5 = 85
=> 3x = 85 + 5
=> 3x = 90
[tex] = > x = \frac{90}{3} [/tex]

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
When conducting research on color blindness in males, a researcher forms random groups with five males in each group. 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.

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.

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.

Which condition would prove ΔDEF ∼ ΔJKL?
Answers
Step-by-step explanation:
DE : JK

#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.

Hello!
[tex]\large\boxed{80 \text{ cookies}}[/tex]
To find the amount of cookies sold, we will need to divide the cost of each cookie from the total raised. Therefore:
Let c = cookies sold
60 = 0.75c
Divide both sides by 0.75:
60 / 0.75 = c
c = 80 cookies.
