An earthquake affected people living within 90 miles of its epicenter. The population density for this region is 125 people per square mile. About how many people live in the region affected by the earthquake?
Answer:
11,250
Step-by-step explanation:
Population density = Number of people / land area
Population density = 125 people per square mile
Number of people = x
Land area = 90 miles
Population density = Number of people / land area
125 = x / 90
Cross product
x = 125 * 90
x = 11,250
About 11,250 people live in the region affected by the earthquake
To find simple interest, you multiply the principal (in dollars), the interest rate (as a decimal), and the time in years. The equation 24 = 400 0.015 4 shows how to find the simple interest for a certain account after 4 years. What is the interest rate (as a percent)? How much is the simple interest? What is the principal?
Answer:
1.5%
$24
$400
Step-by-step explanation:
the equation to find simple interest is
i = p×r×t
i stands for the interest
p stands for the principal
r stands for the rate of interest
t stands for the time in years
in this problem, the equation has already been replaced by numbers
so the i was replaced by the amount of simple interest (24) so thats the answer to the 2nd question
the r was replaced by the rate of interest as a decimal (0.015), and to change that decimal into a percent for the 1st question, just move the decimal point 2 spaces to the right, so in this case it would be 1.5%
and the p was replaced by the principal (400) so thats the answer to the 3rd question
25^x+1 - 5^x+1 = 100

Combining random variables
A large bakery uses a machine to dispense frosting onto its cookies. A certain type of cookie gets 4 dots of
frosting on top of each cookie. The dots of frosting have a mean mass of u = 3 grams and a standard deviation
of 0 = 0.25 grams. We can assume that the masses of the dots of frosting are independent from each other.
Let T be the total mass of the 4 dots of frosting on a randomly chosen cookie.
Find the standard deviation of T.
Choose 1 answer:
OT = 0.25 grams
B
OT = 0.5 grams
OT = 0.75 grams
OT 1 gram
Answer:
0.5 grams
Step-by-step explanation:
The sum of the variance of the 4 dots is equal to the variance of the sum of
the masses of the 4 dots.
The correct option for standard deviation of T is; [tex]\underline{\sigma_T = 0.5 \ grams}[/tex]Reasons:
The given parameter are;
The mean mass of the dots of frosting, μ = 3 grams
The standard deviation of each dot of frosting, σ = 0.25 grams
The total mass of the 4 dots = T
Required:
To determine the standard deviation of T
Solution:
Standard deviation, σ = √(Variance)
Therefore;
Variance, Var = σ²
The sum of the variance of a given number of independent random variable is presented as follows;
[tex]\displaystyle Var \left(\sum_{i=1}^{n} X_i \right) = \mathbf{ \sum_{i = 1}^{n}Var(X_i)}[/tex]The variance of each sample, are; Var(X) = σ² = 0.25²
Therefore, for the four samples, we have;
Var(X₁) = Var(X₂) = Var(X₃) = Var(X₄) = σ² = 0.25²
Which gives;
[tex]\displaystyle \mathbf{Var \left(\sum_{i=1}^{4} X_i \right)} = \sum_{i = 1}^{4}Var(X_i) = Var(X_1) + Var(X_2) +Var(X_3) +Var(X_4)[/tex]
Var(X₁) + Var(X₂) + Var(X₃) + Var(X₄) = 0.25² + 0.25² + 0.25² + 0.25² = 0.25
Therefore;
[tex]\displaystyle Var \left(\sum_{i=1}^{4} X_i \right) =\sigma^2_{1 + 2 + 3 +4} = \sum_{i = 1}^{4}Var(X_i) = \mathbf{0.25}[/tex]
[tex]\displaystyle \sigma^2_T = \sigma^2_{1 + 2 + 3 +4}[/tex]
[tex]\displaystyle Var \left(\sum_{i=1}^{4} X_i \right) =\sigma^2_T = \sum_{i = 1}^{4}Var(X_i) = 0.25[/tex]
[tex]\displaystyle Standard \ deviation \ of \ the \ total \ mass = \sigma_T = \sqrt{ \sum_{i = 1}^{4}Var(X_i)} = \sqrt{ 0.25} = 0.5[/tex]
The standard deviation of the total mass of the 4 dots, (T), [tex]\sigma_T[/tex] = 0.5 grams

The points (4,18) and (14,63) form a proportional relationship. Find the slope of the line through the
points. Then use the slope to graph the line.
The slope is
Answer:
The slope is 4.5
Step-by-step explanation:
Here, we want to find the slope of the line that passes through the given points
Mathematically, we use the slope formula here
Using the slope formula m, we have the equation as follows;
m = (y2-y1)/(x1-x1)
m = (63-18)/(14-4) = 45/10 = 4.5

Offers 2.8%. Both banks compound
interest annually. If Rob wants to
set up a new account with $5,000,
how much more money will he
earn at Charter One over Town
Bank after 25 years?
Answer:
Town Bank
100 + 2.25 = 102.25
102.25/100 = 1.0225
5000 X 1.0225^25 = 8720.73
Charter One
100 + 2.8 = 102.8
102.8/100 = 1.028
5000 X 1.028^25 = 9972.36
9972.36 - 8720.73 = 1251.63

230 ounces = ______ cups
The answer in decimal form is 230 ounces = 28.75 cups
What is unit conversion?It is the conversion of one unit to another unit with its standard conversion.
Example:
1 hour = 60 minutes
1 km = 1000 m
We have,
1 ounce = 0.125 cup
Multiply 230 on both sides.
230 ounces = 230 x 0.125 cups
230 ounces = 28.75 cups
Thus,
23o ounces is equal to 28.75 cups.

pregunta de matematica conteste verdadero o falso el siguiente enunciado : En una razón escrita como fracción el numerador recibe el nombre de antecedente y el denominador recibe el nombre de consecuente el denominador puede ser cualquier numero
Answer: falso.
Step-by-step explanation:
En una fracción, el antecedente siempre es el dividendo (también llamado numerador) y el consecuente es el divisor (también llamado denominador)
Es decir, de momento la parte de: "En una razón escrita como fracción el numerador recibe el nombre de antecedente y el denominador recibe el nombre de consecuente el denominador..."
Es verdadera.
El problema en el enunciado es:
"... el denominador puede ser cualquier número"
Esta parte es falsa, el denominador no puede ser 0.
Entonces el denominador no puede ser cualquier número, y así podemos concluir que el enunciado:
" En una razón escrita como fracción el numerador recibe el nombre de antecedente y el denominador recibe el nombre de consecuente el denominador puede ser cualquier número"
Es falso.

Four years ago, Ana's age was double Rodricks age. In four years, they will both
add up to 56 years old. What ages are they right now?
Answer:
Rod is 17-1/3 and Ana is 30-2/3
Step-by-step explanation:
let x = Rod's age now
then Rod's age 4 years ago was x - 4 and Ana's age then was 2(x-4)
therefore Ana's age now is 2(x - 4) + 4 = 2x - 8 + 4 = 2x - 4
In four years Rod will be x + 4 and Ana will be 2x - 4 + 4 = 2x
Now x + 4 + 2x = 56
3x + 4 = 56
3x = 52
x = 17-1/3 = Rod's age
2x - 4 = 2(14) - 4 = 26-2/3 = Ana's age
Check: in 4 years Rod will be 21-1/3 and Ana will be 34-2/3
21-1/3 +34-2/3 = 56
