Answer:
9 ounces
Step-by-step explanation:
In this equation, we are given two things. We know how much each disc weighs (.9 ounces) and we know how many discs Danny bought (10 discs).
To figure out how much the discs weigh, we must do the following steps:
We first step up the equation: 10 discs times .9 ounces
Then, we multiply the numbers to get our final answer: 10(.9 ounces)= 9 ounces
The 10 discs weigh a total of 9 ounces.

The Education Foundation hosted an annual fundraising dinner. There were 24 dinner tables with 8 chairs at each table. Each dinner ticket cost $12.50. If of the dinner tables were full, how much money was raised from the dinner ticket sales?
$225
⊝
$1,800
⊝
$2,400
⊝
$3,200
Answer:
2,400
Step-by-step explanation:
24 times 8 equals 192, 192 times 12.50 equals 2,400. If this does not help, sorry.
The amount raised is $2400.
Option C is the correct answer.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
There were 24 tables with 8 chairs at each table.
Total chairs.
= 24 x 8
= 192 chairs
Each dinner ticket cost $12.50.
And all the dinner tables were full.
So,
Total amount raised.
= 96 x 12.50
= 2400
Therefore,
The amount raised is $2400.

A company places a seven-digit serial number on each part that is made. Each digit of the serial number can be any number from 0 through 9. Digits can be repeated in the serial number. How many different serial numbers are possible?
Answer: 10,000,000 different numbers are possible.
Step-by-step explanation:
Given: Serial number is of 7 digits.
Choices for digits = 10 (0 to 9)
If digits can be repeated, then by Fundamental principle of counting,
The different serial numbers are possible = [tex]10^7[/tex]
= 10,000,000
Hence, the different serial numbers are possible = 10,000,000
What is the probability that six consecutive integers will be chosen as the winning numbers in a lottery where each number chosen is an integer between 1 and 40 (inclusive)?
Answer:
0.00000911843
Step-by-step explanation:
Since the number chosen is an integer between 1 and 40 (inclusive), it means that the number of terms is 40.
Thus; n = 40
Probability that 6 integers (r = 6) which is number of possible outcomes will be gotten without repetition is gotten by the combination formula which is;
C(n, r) = n!/(r!(n - r)!)
C(40, 6) = 40!/(6!(40 - 6)!)
C(40,6) = 3838380
Now, to select 6 consecutive integers, it can be done in different combinations such as;
(1 - 6, 2 - 7, 8 - 13,...e.t.c)
Total number of favorable outcomes will be 35.
Now,probability that six consecutive integers will be chosen as the winning numbers is;
P(that six consecutive integers will be chosen as the winning numbers) = number of favorable outcomes/number of possible outcomes = 35/3838380 = 0.00000911843

61. The 2003 Statistical Abstract of the United States reported the percentage of people 18 years of age and older who smoke. Suppose that a study designed to collect new data on smokers and nonsmokers uses a preliminary estimate of the proportion who smoke of .30. a. How large a sample should be taken to estimate the proportion of smokers in the population with a margin of error of .02
Answer: Required minimum sample size = 2017
Step-by-step explanation:
Formula : Sample size(n) for population proportion(p):
[tex]n= p(1-p)(\frac{Z^c}{E})^2[/tex] , where E = Margin of error
If p = proportion of smokers
Given: p =0.30 and E=0.02
[tex]z^c[/tex] for 95% confidence level = 1.96
So,
[tex]n=0.30(1-0.30)(\dfrac{1.96}{0.02})^2\\\=0.30(0.70)(98)^2\\\\=2016.84\approx2017[/tex]
Hence, required minimum sample size = 2017

How can you subtract mixed numbers when the fraction in the first mixed numbers is less than the fraction in the second mixed number?
When subtracting mixed numbers, if the fraction in the second mixed number is larger than the fraction in the first mixed number, rewrite the first mixed number by regrouping one whole as a fraction. Alternatively, rewrite all fractions as improper fractions and then subtract.

1) y = 3ˣ = b)
2) y = 3⁻ˣ = a)
3) y = -3ˣ = c)
What are the laws of exponents?When you raise a quotient to a power you raise both the numerator and the denominator to the power. When you raise a number to a zero power you'll always get 1. Negative exponents are the reciprocals of the positive exponents.
The different Laws of exponents are:
mᵃ×mᵇ = mᵃ⁺ᵇ
mᵃ / mᵇ = mᵃ⁻ᵇ
( mᵃ )ᵇ = mᵃᵇ
mᵃ / nᵃ = ( m / n )ᵃ
m⁰ = 1
m⁻ᵃ = ( 1 / mᵃ )
Given data ,
Let the exponential equation be represented as A
Now , the value of A is
a)
y = 3ˣ
Now , the exponential function is plotted on the graph and is represented by the line b
b)
y = 3⁻ˣ
Now , the exponential function is plotted on the graph and is represented by the line a
c)
y = -3ˣ
Now , the exponential function is plotted on the graph and is represented by the line c

Zachary purchased a computer for $1,500 on a payment plan. Six months after he purchased the computer, his balance was $600. Eight months after he purchased
the computer, his balance was $300. What is an equation that models the balance y after x months?
The equation models the balance y after x months
9514 1404 393
Answer:
y = 1500 -150x
Step-by-step explanation:
Apparently, we're to assume that the balance is linear function of the number of months. We are given 3 points:
(0, 1500), (6, 600), (8, 300)
Any two of these can be used to write the equation of the line using the 2-point form:
y = (y2 -y1)/(x2 -x1)(x -x1) +y1
y = (600 -1500)/(6 -0)(x -0) +1500
y = -900/6x +1500
y = 1500 -150x . . . models the balance after x months
