El corredor belga Stefaan Engels tenía el record de correr 365 maratones seguidos. Pero ese record se lo ha arrebatado Ricardo Abad, que con 41 años ha entrado en el libro Guiness, como el que ha corrido durante mas veces seguidas la distancia de 42,195 metros, un total de 500 maratones. ¿En cuántos metros en total corridos estaba el record de Stefaan Engels antes de que Ricardo Abad lo superase?

15401.175  metros

Step-by-step explanation:

El corredor Belga tenía 365 maratones que a razón de 42.195 metros son:

365 *  42.195   =  15401.175  metros

3.4 pizzas

step-by-step explanation:

given is a scatter plot showing number of pizzas sold during weeks for different issues of coupon

y represents number of pizzas sold and x number of coupons issued

y is marked verticaly and x horizontally

the trend line is given as

y =3.4x+43

this says that even when no coupon is issued pizzas sold will be 43

and rate of change of pizza sold for 1 unit of coupon = slope = 3.4

i.e. when x increases by 1 unit y increases by 3.4 units

hence for each additional coupon issued 3.4 pizzas more will be sold
