Answer:
0.3575
Step-by-step explanation:
A population with a normal distribution has a mean of 104 and a standard deviation of 15. A sample of 30 items is taken from that population. (a) (4 points) What is the probability of the sample mean is not less than 103?
The probability of the sample mean is not less than 103 means the sample mean is equal to 103
We solve using the z score formula
z = (x-μ)/σ/√n
where
x is the raw score = 103
μ is the population mean = 104
σ is the population standard deviation = 15
n is the random number of sample = 30
z = 103 - 104/15/√30
z = -1/2.7386127875
z = -0.36515
Probability value from Z-Table:
P(x≤ 103) = 0.3575
Therefore, the probability of the sample mean is not less than 103 is 0.3575
Answer:
El lugar donde la linterna, los bancos y los árboles se encuentran nuevamente está a 300 metros del punto de inicio.
Step-by-step explanation:
Los parámetros dados son;
El espacio entre las linternas = 30 metros.
El espacio entre los bancos = 20 metros.
El espacio entre los árboles = 50 metros.
Por lo tanto, tenemos, la ubicación donde la linterna, los bancos y los árboles se encuentran nuevamente, está dada por el mínimo común múltiplo de cada una de sus distancias de separación individuales como sigue;
2 divide 30 20 50 
<u>5 divide 15 10 25</u>
3 2 5
El LCM = 2 × 5 × 3 × 2 × 5 = 300
El lugar donde la linterna, los bancos y los árboles se vuelven a encontrar está a 300 metros del punto de inicio.
This depends on a lot of factors. A persons weight, height, etc. It also depends on how many calories they want to burn or if they are just looking to run for fun. A lot of different factors play into a persons time to jog.
