What percentage of households in the survey have four or more televisions?

2.5% ?

Step-by-step explanation:

.025 as percentage is 2.5%

$450

step-by-step explanation:

first, you have to multiply 150x2=300

next, you have to add 150+300= 450

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47
