Answer:
above is right
Step-by-step explanation:
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.

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

because a bisector splits in the middle, meaning that whatever the value is for the one side, it's the same on the other. So we multiply by 2.
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]

Are the measures of Z4 and 214 related in
the same way as the measures of 29 and
Z7? Show your work.
Answer:
Step-by-step explanation:
m∠4 + m∠16 = 180° [Consecutive exterior angles]
m∠16 = m∠14 [corresponding angles]
Therefore, m∠4 + m∠14 = 180°
m∠7 + m∠11 = 180° [Consecutive interior angles]
m∠11 = m∠9 [Corresponding angles]
Therefore, m∠7 + m∠9 = 180°
In both the cases sum of the given angles is 180°.
Therefore, measure of ∠4 and ∠14 are related in the same way as the measurement of ∠9 and ∠7.

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.

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

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

Rosa believes she can use a division expression to find the cost per pound of ground beef when 2/3 pound sells for $4. Which statement best explains why Rosa is correct or incorrect? A. Rosa is correct in using a division expression because the term ""per"" implies the quotient of the quantities before and after that word. B. Rosa is correct in using a division expression because the cost per pound should be less than $4. C. Rosa is incorrect in using a division expression because ""cost per pound"" refers to the product of the price and weight. D. Rosa is incorrect in using a division expression because the cost per pound must be an integer.
Answer: A. Rosa is correct in using a division expression because the term ""per"" implies the quotient of the quantities before and after that word.
Step-by-step explanation:
The term ; Cost per pound can be interpreted mathematically to mean;
Cost / pound ; where per means division. In the context above ;
cost per pound = cost of 1 pound of an item ;
(Stated Cost of the item ÷ pound of the item at the stated cost)
For the question above ;
2/3 pounds of ground beef cost $4;
Cost per pound = cost of 1 pound of ground beef ;
= $4 ÷ (2/3)
= $6
Hence, 1 pound of ground beef cost $6
