If Megan's tuition, fees, and expenditures for books this year total $19,000, what will they be during her senior year (three years from now),
assuming costs rise 7 percent annually? Round Future value of a Single
Amount in intermediate calculations to four decimal places.
Answer:
$23,275.817
Step-by-step explanation:
To get this answer, multiply 19,000 by 1.07.
$19,000 x 1.07 = 20,330 (one year later)
$20,330 x 1.07 = $21,753.10 (two years later)
$21,753.10 x 1.07= $23,275.817 (three years later)
The answer round to cents would be $23,275.82
Una caja de 30 kg esta apoyada sobre una de sus caras que tiene 40 cm de ancho y 50 cm de largo. La presion que ejerce sobre el suelo sera
Answer:
294N
Step-by-step explanation:
La presion que ejerce sobre el suelo seria la fuerza de la caja contra el suelo. Esto se calcula multiplicando el peso de la caja por el valor de la gravedad de nuestra tierra. En esta situacion no se necesitaria las dimensiones de la caja.
Fuerza = 30kg * 9.8[tex]m/s^{2}[/tex]
Fuerza = 294N
Fuerza tiene un simbolo de N que significa Newtons que serian calculados como kg * m/s^{2} ... entonces la caja ejerce una fuerza de 294N sobre el suelo.

Tom drove 504 miles in 8 hours. At the same rate, how many miles would he drive in 12 hours
Answer:
756 miles in 12 hours
Step-by-step explanation:
504÷8=63
63 miles per hour
63×12=756
9514 1404 393
Answer:
756
Step-by-step explanation:
If you recognize that 12 (=8 +8/2) is half-again as much as 8, then you would know that Tom would drive half-again as much as 504 miles. That is, he would drive 504 +504/2 = 504+252 = 756 miles in 12 hours.
__
Since the rate is constant, you can write a proportion:
d/12 = 504/8 = distance/time
d = (12/8)(504) 1.5×504 = 756
Tom would drive 756 miles in 12 hours at that rate.

Question:
Choose an equivalent expression for 12^3 • 12^9 • 12^4 • 12^2
A. 12^4 B. 12^18 C. 12^35 D. 12^216
Answer:
[tex]12^{18}[/tex]
Step-by-step explanation:
Given
[tex]12^3 . 12^9 . 12^4 . 12^2[/tex]
Required
Determine the equivalent
Applying law of indices, we have:
[tex]12^{3 + 9 + 4 + 2}[/tex]
[tex]12^{18}[/tex]
Hence:
[tex]12^3 . 12^9 . 12^4 . 12^2 = 12^{18[/tex]

Answer:
80 gallons
Step-by-step explanation:
First to find this, we must divide 10 by 4, and yes I know this will give us a decimal, but it must be done. This division will give us 2.5, we must then multiply 2.5 by 32, as we are given 32 gallons for 4 loads of dishes, and if 2.5 times 4 loads is 10 loads, then we must multiply 32 by 2.5 as well, giving us the answer, 80 gallons
Answer:
80 gallons
Step-by-step explanation:
The answer is 80 gallons when using the distributive, and communitive property of multiplication and division.

how do you simplify 50 1/2 + -12.3
Answer:
I believe you divide it
Step-by-step explanation:
hope this helps u
Answer:
38.2
Step-by-step explanation:
50 1/2=50.5 1/2=.5
50.5 + -12.3 is the same as 50.5 - 12.3
50.5 + -12.3= 38.2
50.5 - 12.3 = 38.2

19. passes through (1, 4) and (-1, 1)
Answer:
y = 3/2x + 2.5
Step-by-step explanation:
Use this formula to find the slope. y2-y2/x2-x1
Plug in
1-4/-1-1= -3/-2 = 3/2
So the slope is 3/2
To find the y-intercept use one of the points you were given. (1,4)
Plug in (1,4)
4 = 3/2(1) + b (b is the y-intercept)
4 = 3/2 + b (minus 3/2 on both sides)
2.5 = b or 5/2 = b
y = 3/2x + 2.5
Suppose 52% of the population has a college degree. If a random sample of size 563563 is selected, what is the probability that the proportion of persons with a college degree will differ from the population proportion by less than 5%5%? Round your answer to four decimal places.
Answer:
The value is [tex]P(| \^ p - p| < 0.05 ) = 0.9822 [/tex]
Step-by-step explanation:
From the question we are told that
The population proportion is [tex]p = 0.52[/tex]
The sample size is n = 563
Generally the population mean of the sampling distribution is mathematically represented as
[tex]\mu_{x} = p = 0.52[/tex]
Generally the standard deviation of the sampling distribution is mathematically evaluated as
[tex]\sigma = \sqrt{\frac{ p(1- p)}{n} }[/tex]
=> [tex]\sigma = \sqrt{\frac{ 0.52 (1- 0.52 )}{563} }[/tex]
=> [tex]\sigma = 0.02106 [/tex]
Generally the probability that the proportion of persons with a college degree will differ from the population proportion by less than 5% is mathematically represented as
[tex]P(| \^ p - p| < 0.05 ) = P( - (0.05 - 0.52 ) < \^ p < (0.05 + 0.52 ))[/tex]
Here [tex]\^ p[/tex] is the sample proportion of persons with a college degree.
So
[tex]P( - (0.05 - 0.52 ) < \^ p < (0.05 + 0.52 )) = P(\frac{[[0.05 -0.52]]- 0.52}{0.02106} < \frac{[\^p - p] - p}{\sigma } < \frac{[[0.05 -0.52]] + 0.52}{0.02106} )[/tex]
Here
[tex]\frac{[\^p - p] - p}{\sigma } = Z (The\ standardized \ value \ of\ (\^ p - p))[/tex]
=> [tex]P( - (0.05 - 0.52 ) < \^ p < (0.05 + 0.52 )) = P[\frac{-0.47 - 0.52}{0.02106 } < Z < \frac{-0.47 + 0.52}{0.02106 }][/tex]
=> [tex]P( - (0.05 - 0.52 ) < \^ p < (0.05 + 0.52 )) = P[ -2.37 < Z < 2.37 ][/tex]
=> [tex]P( - (0.05 - 0.52 ) < \^ p < (0.05 + 0.52 )) = P(Z < 2.37 ) - P(Z < -2.37 )[/tex]
From the z-table the probability of (Z < 2.37 ) and (Z < -2.37 ) is
[tex]P(Z < 2.37 ) = 0.9911[/tex]
and
[tex]P(Z < - 2.37 ) = 0.0089[/tex]
So
=>[tex]P( - (0.05 - 0.52 ) < \^ p < (0.05 + 0.52 )) =0.9911-0.0089[/tex]
=>[tex]P( - (0.05 - 0.52 ) < \^ p < (0.05 + 0.52 )) = 0.9822 [/tex]
=> [tex]P(| \^ p - p| < 0.05 ) = 0.9822 [/tex]
