gordon rolls a fair dice 660 times. how many times would gordon expect to roll a two?
Answer:
110
Step-by-step explanation:
a probabability of rolling a 2 on a dice is 1/6, and times that by 660 is 660/6 which equals 110
hope this helps!
please give brainliest. Thanks!
Answer:
110 times
Step-by-step explanation:
The probability (P) of rolling a 2 is
P(2) = [tex]\frac{1}{6}[/tex]
expected number = [tex]\frac{1}{6}[/tex] × 660 = 110

For the following right triangle, find the side length x. Round your answer to the nearest hundredth.
10
X
13
Answer:
8.31
Step-by-step explanation:
By Pythagoras Theorem,
(10)² + x² = (13)²
=> x² = (13)² - (10)²
=> x² = 169 - 100
=> x² = 69
=> x = [tex]\sqrt{69}[/tex]
=> x ≈ 8.31

It’s for question 4
Answer:
$6,000
Step-by-step explanation:
We have to start by finding the conversation rate.
So, we can divide 9,600 by 8 to find how much the ratio is being multiplied by.
9,600 / 8 = 1200
Now that we know the conversion rate, we can multiply by five to find how much the expenses really cost, according to the ratio.
1200 * 5 = 6000
Their expenses this month are 6000

How to expand this binomial?
Answer:
[tex] {y}^{8} + 8 {y}^{7} + 28 {y}^{6} + 56 {y}^{5} + 70 {y}^{4} + 56 {y}^{3} + 28 {y}^{2} + 8y + 1[/tex]
Answer:
Step-by-step explanation:
This is an ugly binomial expansion, which you should try to remember
These are the coefficients for the power
1,2,1 for power two
1,3,3,1 for p=3
1,4,6,4,1 for p=4
1,5,10,10,5,1 for p=5
you should see a pattern here :)
1,8,28,56,70,56,28,8,1
In general the terms are ordered for the expansion of (a+b) that has the form
a^n(b^0)+a^(n-1)b^1+...a^0(b^n) since we have (y+1)^8 we wind up with
y^8+8y^7+28y^6+56y^5+70y^4+56y^3+28y^2+8y+1
An author receives $0.75 for each hardcover book or paperback book that is sold. There were x hardcover books and 42,000 paperback books sold of her most recent book. The author received a total of $60,000 for the book sales. The equation below can be used to determine the number of hardcover books that were sold. 0.75(x + 42,000) = 60,000. How many hardcover books were sold?
Rizwana borrowed 4500 for three years with simple interest of 7 ½% per annum. How much did she repay?
Answer: 1012.50
Step-by-step explanation:
The formula for calculating Simple interest is:
= Principal × Rate × Time
= 4500 × 7 1/2% × 3
= 4500 × 7.5/100 × 3
= 4500 × 0.075 × 3
= 1012.50
Therefore, the simple interest is 1012.50

hi what is 24/30 simplified to
Answer:
12/15 or .8
Step-by-step explanation:
So first you divide both the numerator and denominator by 2 because it’s the biggest number that goes into both 24 and 30
24 and 30 simplified by 2 gives us 12 and 15
you can’t simplify any further so your answer is 12/15
If you want a decimal, then you divide 24 by 30 and your answer is .8

When a number is decreased by 8.3%, the result is 50. What is the original number to the nearest tenth?
I'm pretty sure the answer would be 2.
Sorry if it's wrong
If a quantity is decreased by x% the new value of that quantity is (100 -x)% of the old one.The value of original number nearest to tenth is 55.
What is percentage?A percentage is a value that indicates 100th part of any quantity.
To convert percentage into a fraction it is divided by 100.
Given that,
The percentage of decrease = 8.3%
The number obtained after decrease = 50
Since the number obtained after decrease is the original number minus the decrement in the number by 8.3%.
Thus, the expression for original number N is given by,
N - 8.3% of N = 50
=> N - (8.3 / 100) × N = 50
=> (91.7 / 100) × N = 50
=> N = 50 × (100 / 91.7)
=> N = 54.52
Nearest to tenth its value is 55.
Hence, the original number nearest to tenth is 55.

Solve the following system of equations using substitution, elimination, or elimination by multiplication
Answer: B
Step-by-step explanation:
Does the table represent an exponential function? Explain.
A. Yes, the x-values decrease by a constant amount and the y-values are multiplied by a constant amount.
B. No, the x- and y-values show a quadratic relationship only.
C. Yes, the x-values increase by a constant amount and the y-values are multiplied by a constant amount.
D. Yes, the y-values increase by a constant amount and the x-values are multiplied by a constant amount.
Answer:
No, because as the x-values are increasing by a constant amount, the y-values are not being multiplied by a constant amount.
Step-by-step explanation:
We have a set of ordered pairs of the form (x, y)
If a function is exponential then the ratio between the consecutive values of y, is always equal to a constant.
This means that:
\frac{y_2}{y_1}=\frac{y_3}{y_2}=\frac{y_4}{y_3}=by1y2=y2y3=y3y4=b
This is: y_2=by_1y2=by1
Now we have this set of points {(-1, -5), (0, -3), (1, -1), (2, 1)}
Observe that:
\begin{gathered}\frac{y_2}{y_1}=\frac{-3}{-5}=\frac{3}{5}\\\\\frac{y_3}{y_2}=\frac{-1}{-3}=\frac{1}{3}\\\\\frac{3}{5}\neq \frac{1}{3}\end{gathered}y1y2=−5−3=53y2y3=−3−1=3153=31
Then the values of y are not multiplied by a constant amount "b"
A bicycle store costs $2700 per month to operate. The store pays an average of $60 per bike. The average selling price of each bicycle is $120. How many bicycles must the store sell each month to break even?
Answer:
The answer would be 45
Step-by-step explanation:
120-60=60 which is how much he gets back from selling a bike. divide 2700/60=45 bicycles that have to be sold.
Which equals (√20-√3) (√20+√3)
Answer:
answer is 17
Step-by-step explanation:
by (a+b)(a-b) = a²-b² identity
(√20-√3) (√20+√3)
= √20²-√3²
=20-3
