Mean= is the summation of the maximum temperatures ÷ the numbers of times the temperatures where recorded
standard deviation= is a number used to tell how measurements for a group are spread out from the average (mean), or expected value.
A low standard deviation means that most of the numbers are very close to the average.
A high standard deviation means that the numbers are spread out.
Variance= is a way to measure how far a set of numbers is spread out.
A variance of zero indicates that all of the data values are identical. All non-zero variances are positive.
A small variance indicates that the data points tend to be very close to the mean, and to each other.
A high variance indicates that the data points are very spread out from the mean, and from one another.
Answer:
Multiply 1/4 ; dividing 4
Step-by-step explanation:
Note that in each number going from left to right, it decreases by dividing 4 each time (or multiplying 1/4)
8/4 = 2 ; 2/4 = 1/2 ; (1/2)/(4) = 1/8 ; etc.
(8)(1/4) = 2 ; (2)(1/4) = 1/2 ; etc.

Answer:
Margarita gastó <u>$40.43.</u>
Step-by-step explanation:
Tenemos la siguiente información.
<u>km recorridos por Margarita</u>
42 km - ciudad
387 km - autopista
<u>Rendimiento del carro</u>
1 galon cada 28 km - ciudad
1 galon cada 36 km - autopista
Hacemos el siguiente factor de conversión
<u>Ciudad</u>
<u>Autopista</u>
Ahoa, se sabe que 1 galon cuesta $3.30. Por lo tanto, el costo de viaje será:
Total galones = 1.5 + 10.75 = 12.25 galones
Total costo = 3.30*12.25 = $40.43.
Espero te haya servido!
