Usa la tabla de Longitud de los tenis para resolver los
problemas 1 a 3.
1. Los estudiantes de tres clases de tercer grado anotaron la
longitud de sus tenis al centímetro más próximo. Los datos
están en la tabla de conteo. ¿Cuántos tenis más había de
18 o 22 centímetros de longitud juntos que de 20 centímetros
de longitud?
Primero, cuenta las marcas de conteo y anota los datos en
una tabla de frecuencias.

Para hallar la cantidad de tenis que miden 18 o
22 centímetros de longitud, suma

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )

step-by-step explanation:

no solution

step-by-step explanation:

there is not enough information in the problem to solve.

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:
