In a housing project there are 350 households in which english is spoken, 50 in which spanish is spoken, and 100 in which the language is other than english or spanish. if a psychologist approaches a house at random to conduct an interview, the chance that the language in that household will not be english? a- .002b- .14c- .3d- .43

  C. 0.3

Step-by-step explanation:

Given : Number of English speaking households =350

Number of Spanish speaking households =50     (1)

Number of households in which the language is other than English or Spanish=100      (2)

Total households participates in this survey =350+50+100=500

No. of households not speak English =100+50=150    (Add (1) and (2))

If a psychologist approaches a house at random to conduct an interview, the chance that the language in that household will NOT be English will be :_

Hence, the correct option is option (c).

8(-10x+3.5y-7)

8×-10x + 8×3.5y + 8×-7

-80x + 28y - 56

therefore

-80x+28y-56 is the correct answer
