Una fabrica produce 132 litros de yogurt diarios .Con 49 litros se llenan botellas de 0,25litros xada una y con el resto que que
Zina [86]

Answer:

z = 362\,botellas

Step-by-step explanation:

(This exercise has been presented in Spanish and for that reason explanation will be held in Spanish)

La cantidad de botellas de 0,25 litros que se llenan con 49 litros de yogurt es:

x = \frac{49\,L}{0.25\,\frac{L}{botella} }

x = 196\,botellas

La cantidad remanente de yogurt es:

V_{r} = 132\,litros - 49\,litros

V_{r} = 83\,litros

Ahora, la cantidad de botellas de 0,5 litros que se llenan con el volumen remanente es:

y = \frac{83\,litros}{0.5\,\frac{litros}{botella} }

y = 166\,botellas

Finalmente, el total de botellas a llenar es:

z = 196\,botellas + 166\,botellas

z = 362\,botellas

Marina can make 36 cupcakes in 45 minutes. How long will it take for her to make 108 cupcakes?
marta [7]
Answer:
135 minutes

Explanation:
36 cupcakes in 45 minutes can be written as \frac{36}{45}, so to find how long 108 will take, you can find it by equating these two fractions:
\frac{36}{45} = \frac{108}{x} 
Simplify by cross division:
divide 45 and 108 by 3 to simplify into this:
\frac{36}{15} = \frac{36}{15}
x = 15 
The rate is 3, so 45 • 3 = 135 minutes.

Another way of looking at it is this:
108 ÷ 36 = 3 this is the rate that you need to multiply the amount of time that it takes to make the cupcakes, so:
45 • 3 = 135 minutes.

The Metropolitan Bus Company claims that the mean waiting time for a bus during rush hour is less than 5 minutes. A random sampl
Wewaii [24]

Answer:

Decision is reject the H_0 as There is sufficient evidence to support the claim that the mean time is less then 5 minutes.

Step-by-step explanation:

Consider the provided information.

The mean waiting time for a bus during rush hour is less than 5 minutes.

Thus the null hypothesis is:

H_0: \mu\geq 5

H_1: \mu< 5

A random sample of 20 waiting times has a mean of 3.7 minutes with a standard deviation of 2.1 minutes. At α = 0.01,

Now use the table to find the z value, where α = 0.01,

t_L = -2.3264

The value of n is 20, sample mean is 3.7, population mean is 5 and standard deviation is 2.1.

Now, use the formula: Standardized test statistic for z-scores =t=\frac{\bar x-\mu_0}{{s}/{\sqrt{n} }}.

Substitute the respective values in the above formula.

t=\frac{3.7-5}{{2.1}/{\sqrt{20} }}

t=\frac{-1.3}{0.47}

t=-2.768465115\approx-2.77

As, the test statistic is in the reject interval, so reject H_0

There is sufficient evidence to support the claim that the mean time is less then 5 minutes.
