7 hours
Step-by-step explanation:
90 divided by 5 is 18 so 126 divideded by 18 is7
Using the normal distribution, it is found that there is a 0.0436 = 4.36% probability that a randomly selected caterpillar will have a length longer than (greater than) 4.0 centimeters.
<h3>Normal Probability Distribution</h3>
The z-score of a measure X of a normally distributed variable with mean and standard deviation is given by:
- The z-score measures how many standard deviations the measure is above or below the mean.
- Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.
In this problem, the mean and the standard deviation are given, respectively, by:
.
The probability that a randomly selected caterpillar will have a length longer than (greater than) 4.0 centimeters is <u>one subtracted by the p-value of Z when X = 4</u>, hence:
Z = 1.71
Z = 1.71 has a p-value of 0.9564.
1 - 0.9564 = 0.0436.
0.0436 = 4.36% probability that a randomly selected caterpillar will have a length longer than (greater than) 4.0 centimeters.

Usando proporciones, se encuentra que al final de la primera hora, el congelador tenía una temperatura de -1ºC.
- Este problema se resuelve por proporciones.
- En 3 horas, la temperatura bajó 12ºC, puesto que .
La temperatura del congelador bajó en la <u>misma cantidad de grados cada hora</u>, o sea, en la primera hora, la cantidad que bajo es:
4ºC bajo a 3ºC es:
O sea, al final de la primera hora, el congelador tenía una temperatura de -1ºC.
