Answer:
C is the right answer I think
Answer:
Step-by-step explanation:
The confidence interval for the population mean x can be calculated as:
Where x' is the sample mean, s is the population standard deviation, n is the sample size and 
is the z-score that let a proportion of 
on the right tail.
is calculated as: 100%-99%=1%
So, 
Finally, replacing the values of x' by 308, s by 17, n by 15 and by 2.576, we get that the confidence interval is:
Answer:
B
Step-by-step explanation:
58×20=1160
0+160+1000=1160
Answer:
Miguel recaudó Bs 480.700.000 por la venta del pescado.
Step-by-step explanation:
Con la información proporcionada puedes calcular el dinero que recaudó en total por la venta del pescado multiplicando el precio de venta de cada kilo de pescado por el número de kilos que Miguel compró:
Número de kilos comprados=253
Precio de venta por kilo=1.900.000
Total vendido=253*1.900.000
Total vendido=480.700.000
De acuerdo a esto, la respuesta es que Miguel recaudó Bs 480.700.000 por la venta del pescado.
Answer:
- w = 8
- x = 8√2
- y = 8√2
- z = 16
Step-by-step explanation:
A 45-45-90 right triangle is isosceles. That means both legs are the same length, and its hypotenuse is √2 times the leg length. You can figure these facts using trigonometry or the Pythagorean theorem, or you can rely on your memory of them.
w = 8 . . . . . . . . . . . same as the leg length shown
x = y = 8√2 . . . . . hypotenuse of smaller triangle; both legs are the same
z = (8√2)√2 = 16 . . . . hypotenuse of larger triangle
