Step-by-step explanation:
Probability theory provides a set of mathematical rules to assign probabilities to outcomes of random experiments, e.g., coin flips, packet arrivals, stock prices, neural spikes.
a. True
b. False
Answer: True
Step-by-step explanation:
Probability theory, is a mathematical branch that has to do with how random phenomena are analysed. To solve for probability, one has to divide the number of events aggregate by the amount of possible outcomes.
We should note that the statement in the question regarding probability theory providing mathematical rules that are assigned probabilities to the outcomes of the random experiments is said to be true.
Which expression is a factor of 64x^2−25?
8x−5
32x−25
32x−5
8x−25
Answer:
A
Step-by-step explanation:
Answer:
[tex](8x-5)^{2}[/tex]
Step-by-step explanation:
Rewrite 64[tex]x^{2}[/tex] as [tex](8x)^{2}[/tex]
[tex](8x)^{2}[/tex]−80x+25
Rewrite 25 as 5^2.
(8x)^2−80x+5^2
Check that the middle term is two times the product of the numbers being squared in the first term and third term.
80x=2⋅(8x)⋅5
Rewrite the polynomial. [tex](8x)^2[/tex]−2⋅(8x)⋅5+[tex]5^{2}[/tex]
Factor using the perfect square trinomial rule [tex]a^{2}[/tex] −2ab + [tex]b^{2}[/tex]= [tex](a-b)^{2}[/tex], where a=8x and b=5.
[tex](8x-5)^{2}[/tex]
Kelsey has a bag containing yellow, blue, red or purple marbles. There are a total of 24 marbles in the bag. Kelsey randomly selects a marble from the bag and then puts it back. She repeats this process 15 times. If Kelsey selected a yellow marble five times, what is the most likely number of yellow marbles in the bag?
Answer:
6 yellow because there are 4 colors so 24/4=6
she selected it 5 times and just add 1

Hey there!
The correct graph is A
The slope, 2, is a positive slope, which means that the graph will go left to right going up, which rules out graph B.
The y-intercept is 1, which means it will intercept the y-axis at point (0, 1). That rules out graph C.
This means that graph A is correct.
Hope it helps and have a great day!
Answer:
○ [tex]\displaystyle a[/tex]
Step-by-step explanation:
From the y-intercept of [tex]\displaystyle [0, 1],[/tex] you can either move two blocks south over one block west, or two blocks north over one block east. Either way, you are still using the rate of change [slope] correctly:
[tex]\displaystyle \frac{-y_1 + y_2}{-x_1 + x_2} = m[/tex]
I am joyous to assist you at any time.

Part B: What is the equation of the line that passes through these points.
Part C: Where does the line intersect the x-axis and y-axis?
Answer: (hope I got them correct)
A) -15/7
B) [tex]y=-\frac{15}{7}x-\frac{4}{7}[/tex]
C) It cuts the x-axis at (-4/15,0) and the y-axis at (0,-4/7).
Step-by-step explanation:
A) Slope = [8-(-7)]/(-4-3) = -15/7
B) Let [tex]y=-\frac{15}{7}x+c[/tex] be the required equation.
Substitute x=-4, y=8.
8=(-15/7)(-4)+c
c=-4/7
The equation is therefore [tex]y=-\frac{15}{7}x-\frac{4}{7}[/tex].
C) Substitute y=0, we will get x = -4/15 i.e. it cuts the x-axis at (-4/15,0).
Substitute x=0, we will get y = -4/7 i.e. it cuts the y-axis at (0,-4/7).
Find cos(a) in the triangle.
The value of Cosα from the triangle is 21/29
ABC is a right angled triangle
We have to find the Cosα
We know that cosine function is a ratio of adjacent side and hypotenuse
Let us find the value of Cosα
The adjacent side of angle α is 21
The hypotenuse is 29 in the triangle
Cosα = Adjacent side/hypotenuse
Plug in the values of adjacent side and hypotenuse
Twenty one divided by twenty nine
=21/29
Hence, the value of Cosα from the triangle is 21/29

Answer:
using elimination, the best first step is multiply the first equation by -3. multiply the second equation by 3 doesn't do anything to eliminate one of the unknowns. solving for x in the first equation or solving for y in the second equation are the substitution method, not the elimination method.

Answer:
Kate did 15/8 part more than that of John.
Step-by-step explanation:
Given that,
John did 3 3/4 of his homework while Kate did 1 7/8 of her homework.
We need to find how much more of their homework did Kate do than John. It can be calculated as follows :
3 3/4 = 15/4
and
1 7/8 = 15/8
So,
Difference,
[tex]d=\dfrac{15}{4}-\dfrac{15}{8}\\\\=\dfrac{15}{8}[/tex]
So, the required answer is 15/8.

If 176 dollars = 100 pounds and 1 pound = NRs. 119,
how much Nepali rupees can be exchanged with 132 dollar? find it
Answer:
NRs. 8925
Step-by-step explanation:
176 dollars = 100 pounds
132 dollars = ??? pounds
Using cross-multiplication, we get:
176 dollars x ??? pounds = 100 pounds x 132 dollars
??? pounds = (100 pounds x 132 dollars)/ 176 dollars
??? pounds = 75 pounds
Now, 1 pound = NRs. 119
So 75 pounds = NRs. ???
Using cross-multiplication again, we get:
1 pound x NRs. ??? = NRs. 119 x 75 pounds
NRs. ??? = (NRs. 119 x 75 pounds)/1 pound
NRs. ??? = NRs. 8925
So the answer is 8925 Nepali rupees
The Nepali rupees can be exchanged with 132 dollar should be considered as the NRs. 8925
Calculation of the amount:Since
176 dollars = 100 pounds
And, for 132 dollars = ??? pounds
So here we applied cross multiplication
176 dollars x ??? pounds = 100 pounds x 132 dollars
??? pounds = (100 pounds x 132 dollars)/ 176 dollars
??? pounds = 75 pounds
Also, 1 pound = NRs. 119
Now
1 pound x NRs. ??? = NRs. 119 x 75 pounds
NRs. ??? = (NRs. 119 x 75 pounds)/1 pound
NRs. ??? = NRs. 8925

Find the rule and the graph of the function whose graph can be obtained by performing the translation 2 units left and 3
units up on the parent function f(x)=x?
Answer:
b.
Step-by-step explanation:
1. You have the following parent function given in the problem above:
f(x)=x³ (This is the simplest form. We need to translate it 3 units left and 2 units down)
2. If you take the parent function and make y=f(x+3), then you have:
(The function is shifted 3 units left on the x-axis).
3. Then you if you make y=f(x+3)-2, as following, you obtain:
(The function is shifted 2 units down on the y-axis).
4. Therefore, that is how you obtain the final function.
The answer is the graph shown in .b
