Answer:
Un excursionista camina por un prado llano, observando una montaña a
lo lejos. Mide que el ángulo de elevación entre el suelo
y la cima de la montaña es de 25 grados. Camina 5 millas y luego
mide el ángulo de elevación nuevamente, ahora es de 40 grados. ¿Qué altura tiene
la montaña?
Step-by-step explanation:
8÷(3-(8÷3))
8 divided by 3 minus 8 divided by 3.
Make sure to include the brackets otherwise the answer will not work.
Y+4x =7
Or y = -4x + 7
On comparing with point slope form
y = mx+c
We get m = -4 = slope of given line
As the required line is parallel to given line its slope is equal to -4
Answer:
140
Step-by-step explanation:
46+94 = 140
Answer:
A . About 95% of all random samples of 50 students from this population would result in a 95% confidence interval that covered the population mean number of hours of sleep per day.
Step-by-step explanation:
x% confidence interval:
A confidence interval is built from a sample, has bounds a and b, and has a confidence level of x%. It means that we are x% confident that the population mean is between a and b.
In this question:
95% CI from a sample of 50 students is (6.73, 7.67).
This means that we are 95% sure that the population mean is in this interval, that is, about 95% samples of 50 would contain the population mean, which is given by option A.
