There are 6 toppings at an ice cream shop. You can choose any number of toppings from 0 all the way up to 6 (if you don't mind combining things like gummy bears and Oreo crumbles). How many possible ways are there to choose your toppings.

Answers

64
There are 6 options so it would be 2^6
If you don’t count the empty set it would be 63.

I’m pretty sure this is right I did it in my head so lmk if I’m wrong lol

The number of ways in which the selection of toppings can be made are 36.

What is combination? What is a mathematical function, equation and expression?combination : combination is a combination of [n] things taken [k] at a time without repetition. Mathematically -

        [tex]$_n C_r=\frac{n !}{r ! (n-r) !}[/tex]

function : In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.expression : A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.equation : A mathematical equation is used to equate two expressions.

Given is that there are 6 toppings at an ice cream shop. You can choose any number of toppings from 0 all the way up to 6.

The total number of ways in which the selection can be made are -

x = 6 x 6 = 36

[x] = 36

Therefore, the number of ways in which the selection of toppings can be made are 36.

Legend has it that the great mathematician carl friedrich gauss ​(1777dash–​1855) at a very young age was told by his teacher to find the sum of the first 100 counting numbers. while his classmates toiled at the​ problem, carl simply wrote down a single number and handed the correct answer in to his teacher. the young carl explained that he observed that there were 50 pairs of numbers that each added up to 101. so the sum of all the numbers must be 50 times •101equals=5050. modify the procedure of gauss to find the sum. 1plus+2plus+3plus+...plus+320

Answers

Answer: Sum is  51360

Step-by-step explanation: I have heard same legend and it is also told in hih school math books.

There are 160 pairs numbers which sum is 321, also (320 +1) + (319+2) + ... + (160 + 161).    So sum is  160·321

Consider the following exponential probability density function.  for x ≥ 0 If needed, round your answer to four decimal digits.(a) Find P(x ≤ 2). (b) Find P(x ≥ 3). (c) Find P(x ≤ 5). (d) Find P(2 ≤ x ≤ 5).

Answers

Answer:

Here the general formula is

[tex]P(X\leq x_{0} )=1 - e^{\frac{-x_{0}}{2} }[/tex]

a) [tex]P(X\leq 2 )= 0.6321[/tex]

b) [tex]P(X\geq 3 )= 0.2231[/tex]

c) [tex]P(X\leq 5 )= 0.9179[/tex]

d) [tex]P(2\leq X\leq 5 )= 0.2858[/tex]

Step-by-step explanation:

Now the solutions are,

a)

[tex]P(X\leq 2 )=1 - e^{\frac{-2}{2} }\\P(X\leq 2 )= 0.6321[/tex]

b)

[tex]P(X\geq 3 )=1-[1 - e^{\frac{-3}{2} }]\\P(X\geq 3 )= 0.2231[/tex]

c)

[tex]P(X\leq 5 )=1 - e^{\frac{-5}{2} }\\P(X\leq 5 )= 0.9179[/tex]

d)

[tex]P(2\leq X\leq 5 )=1 - e^{\frac{-5}{2} }-1 - e^{\frac{-2}{2} }\\P(2\leq X\leq 5 )= 0.2858[/tex]

Can someone please help me ?

Answers

Answer:

(x-2),(x-1),(x), and(x+1)

Step-by-step explanation:

In this scenario, we are given nothing about the polynomial except its graph. We can start in problems like these by looking at when y=0 and going from there.

In this graph, we can see that y=0 when x=2, 1, 0, and -1. Looking at our options, for y to be 0, there must be a factor where, when we plug x=2 in, y=0. The only option here is (x-2). Similarly, for x=1, we have (x-1), for x=0, we have x, and for x=-1, we have (x+1). The polynomial has 3 turning points, so the polynomial must be of degree 4 or higher.

So far, we have (x-2)(x-1)(x)(x+1). Plugging this in to a graphing calculator, we can see that this fits. To check if x²+2 and x²+1 would work here, it would require guess and check with values/graphing calculators, seeing if they fit. For example, when x=1.5, y is greater than -1 on the graph and our function. However, if we multiplied that by x²+1 or x²+2. when x=1.5, y would balloon downward, and the graph wouldn't fit
