Answer:
A. P(x=17) = 0.00121
B. P(x=10) = 0.15768
C. P(x=12)=0.0888
D. No , x can take any value more than 8
complete sentence or two
Step-by-step explanation:
Here n= 24 ; p= 0.39 ; q = 1-0.39= 0.71
Applying binomial probability distribution
P(X=x) = nCx p^x q^n-x
Part A.
P(x=17) = 24c17 p ^17 q^24-17
P(x=17) = 0.00121510493
Part B.
P(x=10) = 24c10 p ^10 q^24-10
P(x=10) = 0.1576877824
Part C.
P(x=12) = 24c12 p ^12 q^24-12
P(x=12)=0.08887201897
D. The random variable X can obviously take on anyone of the (n+1) integer value 0,1,23,-------,n in the binomial probability distribution
where
the trials are fixed

Answer:
3. D 4. B
Step-by-step explanation:
3. e^2 = g^2 + f^2, answer is d
4. Let a = 3, b = 4, c = 5
2c = 10
2b = 8
2a = 6
10^2 = 8^2 + 6^2
answer is b
3. The Pythagorean theorem states the hypotenuse squared is equal to each side squared added to each other.
The answer is D. E^2 = f^2 + g^2
4.
To keep the proportion you could multiply the sides by the same numbers . The answer would be 2A, 2b, 2c
Plz help me !!!! I’m not sure if it’s 20 !
Answer:
D) 20º
Step-by-step explanation:
if one angle is 70º, and the other is 90º, that means that the first two angles equal 160º. since all three interior angles of a triangle have to add up to 180º, the third angle must be 20º.
A chef divided 24.7 grams of salt into two equal piles. How much salt is in each pile? Enter your answer in the box. g
Answer: 12.35
Step-by-step explanation: Since we know that there is a total of 24.7 grams in both piles, we can find how much salt is in one by dividing 24.7 by 2.
The amount of salt in each pile will be the half amount of 24.7 grams thus 12.35 grams will be in each pile.
What is the arithmetic operator?Arithmetic operators are four basic mathematical operations in which summation, subtraction, division, and multiplication involve.,
Division = divide any two numbers or variables called division.
For example 4/8
As per the given,
Amount of salt available = 24.7 grams.
It needed to divide into two piles.
In one piles = 24.7/2 = 12.35 grams
Hence "The amount of salt in each pile will be the half amount of 24.7 grams thus 12.35 grams will be in each pile".

A radioactive isotope is decaying at a rate of 15% every hour. Currently there are 150 grams of the substance. Write an equation that will represent the number of grams present after n hours. How much will be left one day from now?A radioactive isotope is decaying at a rate of 15% every hour. Currently there are 150 grams of the substance. Write an equation that will represent the number of grams present after n hours. How much will be left one day from now?
Answer:
The equation that will represent the number of grams present after n hours is [tex]A(n) = 150(0.85)^n[/tex]
3.035 grams will be left one day from now.
Step-by-step explanation:
Exponential equation for the amount of a substance:
The exponential equation for the amount of a substance is given by:
[tex]A(t) = A(0)(1-r)^t[/tex]
In which A(0) is the initial amount and r is the decay rate, as a decimal, and t is the time period.
A radioactive isotope is decaying at a rate of 15% every hour.
This means that [tex]r = 0.15[/tex]
Currently there are 150 grams of the substance.
This means that [tex]A(0) = 150[/tex]
Write an equation that will represent the number of grams present after n hours.
[tex]A(n) = A(0)(1-r)^n[/tex]
[tex]A(n) = 150(1-0.15)^n[/tex]
[tex]A(n) = 150(0.85)^n[/tex]
How much will be left one day from now?
One day is 24 hours, so this is A(24).
[tex]A(24) = 150(0.85)^{24} = 3.035[/tex]
3.035 grams will be left one day from now.

Answer:
A. make a point on the line to the right 2 units from 0
B. the opposite of 2 isn't located at the same place as point P on the number line because the opposite of 2 is -2 and the point P is the opposite of negative 2 which would be positive 2. So the two points are not in the same place because they have different signs.

What is one thing that you found interesting about future value and present value for compound interest? 100 words ^
Answer:
Compound interest is that which, once generated, is added to the capital, in order to expand the calculation base on which, in turn, new interests will be generated. Thus, in short, if the interest is, for example, 5 percent, said interest will be added to the initial capital, with which that 5% generated will be increasing, since it will be calculated on an increasingly large basis.
Compound interest is very important for financial investments, as it maximizes the results of said investments, even more so when compared to simple interest, in which the interest generated is not added to the initial capital.

find the area of the figure below, composed of a rectangle with two semicircles removed. Round to the nearest tenths place.
Answer:
Area of figure = 11.43 unit² (Approx.)
Step-by-step explanation:
Given:
Length = 6 unit
Width = 4 unit
Radius = 4/2 = 2 unit
Find:
Area of figure
Computation:
Area of figure = Area of rectangle - 2[Area of hemisphere]
Area of figure = [l x b] - 2[(πr²)/2]
Area of figure = [6 x 4] - 2[(3.14 x 2²)/2]
Area of figure = 24 - 12.57
Area of figure = 11.43 unit² (Approx.)

Must understand distance and slope formula first:
slope y_2-y_1/x_2-x_1
distance d=√((x_2-x_1)²+(y_2-y_1)²)
(Just search up the formulas if this isn't clear)
Step-by-step explanation:
For #13 take two points and put them in the distance formula remember (#,#) the first # is 'x' the second # is the 'y' in a point.
then you could simply type all that in a calculator and a single number should pop up indicating one of the lines (doesn't matter the #) then do the same for the second points (cuz you used two already you have two left) If the number is same as the first two points it's a pallelagram. (I tested it out got 7.07...)
For the slope you're doing something similar to the distance formula, you're filling out two sets of points into the slope formula if they come out the same # it's parallel.
