I need answer ASAP: You are running a fuel economy study. One of the cars you find is blue. It can travel 40 1/2 miles on 1 1/4 gallons of gasoline. Another car is red. It can travel 22 2/5 miles on 4/5 gallons of gasoline. What is the unit rate for miles per gallon for each car? Which car could travel the greater distance on of gasoline?
Answer:
Blue: 32.4 mpg
Red: 28 mpg
The Blue car will travel farther on a gallon of gasoline
Step-by-step explanation:
Blue: 40.5/1.25=32.4 mpg
Red: (22 2/5)/(4/5) =22.4/0.8=28 mpg

2. Which of the following is the correct interpretation of confidence interval? (circle one)
a. If the same experimental process is done on many samples, with a given percentage certainty,
the population parameter will fall within a calculated range.
b. When many different processes are done on the same sample, with a given percentage certainty,
the population parameter will fall within a calculated range.
c. If the same experimental process is done on many samples, with a given percentage certainty,
each sample will determine its own calculated range with a given percentage certainty
3. In a certain study, a population parameter is predicted to be in the interval (42, 60) at a 95% confidence

Mr datu has enough money to pay 8 workers for 15 days if he adds 4 more workers for how long can he pay at the same rate?
Answer:
10 days
Step-by-step explanation:
Mr Datu can pay 8 workers for 15 days,
Then at the same rate he can pay 1 worker for the number of days = 15×8
= 120
If he adds number of workers = 4
Then total number of workers = 8 + 4 = 12
With the same rate Mr Datu can pay 12 workers for number of days = [tex]\frac{120}{12}[/tex]
= 10 days
Therefore, Mr Datu can pay 12 workers for 10 days a the same rate.

En un triángulo obtusángulo, uno de los ángulos mide 20° mas que el otro. El tercer ángulo, mide el doble que el mayor de los dos que hemos citado. ¿?Cuánto miden los ángulos de dicho triángulo
Answer:
La medida del primer ángulo es 30°, la medida del segundo ángulo es 50° y el tercer ángulo mide 100°.
Step-by-step explanation:
Siendo "x" el valor de un ángulo del triángulo obtusángulo, sabes que uno de los ángulos, llamado segundo ángulo, mide 20° más que el primero. Este segundo ángulo se representa como x + 20°.
Además, un tercer ángulo mide el doble que el mayor de los dos, que en este caso es el ángulo cuya expresión es x + 20°. Por lo que el doble de este será 2*(x + 20)°, que será la medida del tercer ángulo.
Teniendo en cuenta que la suma de los ángulos interiores de un triángulo es 180°. Entonces, es posible sumar los valores de cada uno de los ángulos e igualarlos a 180°:
x + x + 20° + 2*(x + 20°) = 180°
Resolviendo:
x + x + 20° + 2*x + 2*20° = 180°
x + x + 20° + 2*x + 40° = 180°
4*x + 20° + 40° = 180°
4*x + 60° = 180°
4*x = 180° - 60°
4*x = 120°
x = 120° ÷ 4
x = 30°
Entonces, la medida del primer ángulo es 30°. El segundo ángulo es calculado como x + 20° = 30° + 20° = 50° mientras que el tercer ángulo es 2*(x + 20°) = 2*(30° + 20°) = 2*(50°) = 100°
La medida del primer ángulo es 30°, la medida del segundo ángulo es 50° y el tercer ángulo mide 100°.
If f(x) = 3x - 15, what is f(4)?
A. 3
B. -3
c. 12
D. -8
Answer:
B. -3
Step-by-step explanation:
f(x) = 3x - 15
f(4) means x=4, so you want to plug 4 into the equation.
f(4) = 3(4) - 15
f(4) = 12 - 15
f(4) = -3
Answer:
B
Step-by-step explanation:
f(4) has the same meaning (for this question ) as x = 4
Let x = 4
f(4) = 3*4 - 15
f(4) = 12 - 15
f(4) = - 3
B
Six more than twice a number is greater than negative fourteen. Solve the inequality for the unknown number
Answer:
Step-by-step explanation:
2x+6 > -14
Subtract 6 from both sides
2x > -20
Divide both sides by 2
x > -10
The solution of the inequality 2x + 6 > - 14 will be greater than the negative 10.
What is the solution to the equation?The distribution of weights to the variables involved that establishes the equilibrium in the calculation is referred to as a result.
Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.
Six more than twice a number is greater than negative fourteen.
Let x be the number. Then the equation will be
2x + 6 > - 14
Simplify the inequality, then the value of x will be
2x > - 20
x > - 10
The solution of the inequality 2x + 6 > - 14 will be greater than the negative 10.

Ok need help this is the question :Use the Pythagorean theorem to write an equation for the distance Jane's trainer bikes.
Answer:
Jane traveled 8 miles farther then her trainer
Step-by-step explanation:
The Pythagora's Theorem
In any right triangle, the square of the measure of the hypotenuse is the sum of the squares of the legs. This can be expressed with the formula:
[tex]c^2=a^2+b^2[/tex]
Where
c = Hypotenuse or largest side
a,b = Legs or shorter sides
Jane's path from the Health Club to the end of her route describes two sides of a right triangle of lengths a=16 miles and b=12 miles.
Her total distance traveled is 16 + 12 = 28 miles
Her trainer goes directly from the Health Club to meet her through the hypotenuse of the triangle formed in the path.
We can calculate the length of his route as:
[tex]c=\sqrt{16^2+12^2}[/tex]
[tex]c=\sqrt{256+144}=\sqrt{400}=20[/tex]
c = 20 miles
The difference between their traveled lengths is 28 - 20 = 8 miles
Jane traveled 8 miles farther then her trainer
Solve for c: c=5 5/6 x 2
Hi there!
c=11 2/3
1.Convert 5 5/6 into mixed number:
[tex]5 \frac{5}{6}=\frac{35}{6}[/tex]
2.Convert 2 into fraction term:
[tex]2=\frac{2}{1}[/tex]
3.Convert both fraction into same denominator:
[tex]\frac{35}{6}=\frac{35}{6}[/tex]
[tex]\frac{2}{1}=\frac{12}{6}[/tex]
4.Multiply the two terms:
[tex]\frac{35}{6}[/tex]·[tex]\frac{12}{6}=\frac{70}{6}[/tex]
5.Simplfly the fraction term:
[tex]\frac{70}{6}=\frac{35}{3}[/tex]
[tex]\frac{35}{3}=11 \frac{2}{3}[/tex]
Therefore, c=11 2/3.
