The experimental probability of winning a game is 2/7. How many times can you expect to win the game if you play 56 times?
Question options:
7
56
16
8
Answer:
You would expect to win the game 16 times.
Step-by-step explanation:
I set up a proportion for this :
2/7 = x/56
2(56) = 7x (cross multiply)
112 = 7x (multiply 2 and 56)
x = 16 (divide 7 from both sides)

Gabriel owns a small business selling used books. He knows that in the last week 89 customers paid cash, 20 customers used a debit card, and 30 customers used a credit card.
Based on these results, express the probability that the next customer will pay with a credit card as a decimal to the nearest hundredth.
Answer:
.22 chance next customer pays with credit card
Step-by-step explanation:
This is because there was in all 139 customers during that week, and 30/ 139 0.21582733812. This rounded to hundredth would be .22

2.a) n represents the no of phones he sells.
so if he charges $10 for a phone, then
n × 10 will represent the amount of money he makes for the no of phones he sells. you are given that P represents the amount of money he makes from selling a phone which is 10N and also his weekly salary, $ 250. this is the amount of money he receives for the whole week.
Hence, 10n + 250 = P
ans: P= 10n + 250
b) the next week he sells 20 phones. he charges $10 per phone. then he will make $200 from selling the phones. but he will also receive his weekly salary, which is $250. total money he receives equals $450.
a better way to reach the answer is using the above equation:
P = 10n + 250, where n= 20
P= (10*20) + 250
P= $450

Given the functions f(x) = 6x 11 and g(x) = x2 6, which of the following functions represents f[g(x)] correctly? f[g(x)] = 36x2 132x 127 f[g(x)] = 36x2 132x 121 f[g(x)] = 6x2 47 f[g(x)] = 6x2 36.
Function defines relationship between variables. The value of the f[g(x)] when the value of f(x)=6x+11 and g(x)=x²+6 is f[g(x)]= 36x²+47.
What is a function?A function assigns the value of each element of one set to the other specific element of another set.
Given to us
f(x) = 6x + 11
g(x) = x² + 6
As we know the two functions, given to us f(x) = 6x + 11, therefore substitute the value of x as g(x) in order to find the value of f[g(x)] ,
[tex]f(x) = 6x + 11\\\\f[g(x)] = 6(x^2 + 6) + 11\\\\f[g(x)] = 6x^2 + 36 + 11\\\\f[g(x)] = 6x^2 + 47[/tex]
Hence, the value of the f[g(x)] when the value of f(x)=6x+11 and
g(x)=x²+6 is f[g(x)]= 36x²+47.

Answer: Option 2
The line starts at an x of -4, so the domain is from -4 to infinity since the arrow goes off the graph, meaning it keeps going. The line starts on a y of 2, and the line continues up with the arrow pointing slightly up, so the range is from 2 to infinity.
The domain is from left to right, and the range is down to up
Answer:
2. {x | x ≥ −4}; {y | y ≥ 2}
Step-by-step explanation:
Let's try to determine the domain first. Look at the x values. The function begins at -4, so our possible domain values also begin at -4, and the values continue positively after -4.
Therefore, our domain is: Domain: {x ≥ -4}.
Or, we could assign our domain using interval notation: [-4,infinity).
Our range, or y values, begin at 2 and continue positively after 2.
Therefore, our range is: Range: {y ≥ 2}.
Again, we could use interval notation to assign our range: [2,infinity)
Therefore, the answer would be
2. {x | x ≥ −4}; {y | y ≥ 2}

If we multiply three consecutive integers and then add the middle number to the result, the answer is always the middle number cubed.
5 × 6 × 7 + 6 = 216 = 63
10 × 11 × 12 + 11 = 1331 = 113
15 × 16 × 17 + 16 = 4096 = 163
Use what you have learned in this lesson to write a third-degree polynomial expression in factored form and standard form that represents this pattern. Show that the factored form is equivalent to the expression written in standard form. Substitute three different values for the variable to prove this pattern works for other numbers.
Step-by-step explanation:
Let use have a interger,n
Thus three consectice intergers can be represented by
[tex]n[/tex]
[tex]n + 1[/tex]
[tex]n + 2[/tex]
Multiply, and we get
[tex]n(n + 1)(n + 2)[/tex]
[tex]n( {n}^{2} + 3n + 2)[/tex]
[tex]n {}^{3} + 3 {n}^{2} + 2n[/tex]
Then add the middle number, n+1.
[tex] {n}^{3} + 3n {}^{2} + 3n + 1[/tex]
We must prove that the middle number cubed = the equation.
Using the binomial theroem,
[tex](n + 1) {}^{3} = {n}^{3} + 3( {n}^{2} 1 {}^{1} ) + 3n( {1}^{2} ) + 1 {}^{3} [/tex]
[tex](n + 1 ){}^{3} = {n}^{3} + 3 {n}^{2} + 3n + 1[/tex]
So this is indeed true.
You can do the subsitue variables for n to prove it.
Solve by the elimination method. Check your work.
Answer:
1: x = 19 y = 16 ; 2. x = 5 y = -4
Step-by-step explanation:
To check your work plug the numbers back into one of the equations and see if it's true.
For example:
10(19)-9(16)=46
46=46
1. I distributed 3 to all the numbers so that 9y and -9y would cancel then you add like terms.
2. I distributed -4 to all the numbers so that 4x and -4x would cancel. Then add all like terms.
Once you get x or y plug it back into one problem to get the other variable.
