In a survey, 200 people were asked if they smoke and whether or not they exercise regularly (more than twice a week). The result

siniylev [52]

Answer/Step-by-step explanation:

a. % of people who smoke = no. of people who smoke ÷ total no. of people surveyed × 100

Total no. of people who smoke is given = 4 + 36 = 40

Total people surveyed = 200

% of people who smoke = $\frac{40}{200}*100 = \frac{40}{2}*1 = 20 percent$

a. % of people who do not exercise regularly = no. of people who do not exercise regularly ÷ total no. of people surveyed × 100

Total no. of people who do not exercise regularly = 36 + 134 = 170

Total people surveyed = 200

% of people who smoke = $\frac{170}{200}*100 = \frac{170}{2}*1 = 85percent$

Please help! It would be very much appreciated :)

Answer:

Cos 45=6/x

x=6/cos 45=6√2

x=6√2

tan 45=y/6

y=tan45 ×6

y=6

sin 60=y/10

y=sin60×10

y=5√3

again

Cos 60=x/10

x=½×10

x=5

Sin 45=x/5

x=1/√2×5 or

x=5√2/2

again

y=5√2/2 or 5/√2[base angle of right angled isosceles triangle]

Sin 30=8/x

½×x=8

x=8*2

x=16

again

cos 30= y/x

√3/2×16=y

y=8√3

sin 60=7/x

x=7/[√3/2]

x=14/√3 or 14√3/3

again

cos 60=y/x

½×14√3/3=y

7√3/2=y

y=7√3/2

Note:

Sin angle =perpendicular/hypotenuse

Cos angle =base/hypotenuse

Tan angle =perpendicular /base

5x^2-(3xy-7x^2)+(5xy-12x^2) When x=-0.25, and y=4

prohojiy [21]

$5x^2-(3xy-7x^2)+(5xy-12x^2)=5x^2-3xy+7x^2+5xy-12x^2=2xy\\\\ 2\cdot(-0.25)\cdot4=-2$
