It’s B) Research database
<span>Members lifted weights: W=32%
</span><span>Members preferred aerobics: A=41%
</span>Members preferred both: B=6%
Members lifted weights only: Wo=W-B=32%-6%→Wo=26%
Members preferred aerobics only: Ao=A-B=41%-6%→Ao=35%
F<span>ind the probability that the member prefers another method neither weights nor aerobics to exercise: N=?
N=100%-Wo-Ao-B
N=100%-26%-35%-6%
N=100%-67%
N=33%
Answer: T</span>he probability that the member prefers another method neither weights nor aerobics to exercise is 33%
The answer is: directional research hypothesis
directional research hypothesis is a form of prediction that initiated in order to guess whether two variables would experience some sort of positive or negative changes. In the example above, boys and girls are the variables and whether they agree or disagree with school rules are the changes.
C da heck dont trains come whenever or am i just dumb
15% of 15 is 2.25, meaning the tip will be $2.25
So now for sales tax. 5% of 15 is .75, meaning sales tax will be $0.75
So now, for the total cost, 15+2.25+0.75= 18
So with tax and tip, the total wil be $18.00
