Alberto is a waiter. He waits on a table of 4 whose bill comes to $110.05. If Alberto receives a 15% tip, about how much will he
RSB [31]

If the total bill comes to $110.05, we know that we are going to have to take 15% of this for his tip.

So we convert 15% to a decimal by dividing by 100:

\frac{15}{100}=0.15

Then we multiply this by the amount of the bill:

110.05*0.15=16.5075

So if we round this to the nearest cent, we get $16.51.

Therefore, Alberto's tip will be about $16.51.

Nadya [2.5K]

Answer:

y= -0.3x - 5.6

Step-by-step explanation:

m= (-5)-(-8)/(-2)-8

m= -0.3

y=mx+c

-8= -0.3(8)+c

-8= -2.4 +c

-8+2.4=c

c= -28/5

y= -0.3x - 5.6

soldier1979 [14.2K]

Answer:

Yes, result is significant ; PVALUE < α

Step-by-step explanation:

Given :

x = 536

n = sample size = 1012

Phat = x / n = 536 / 1012 = 0.5296 = 0.53

H0 : P0 = 0.5

H1 : P0 > 0.5

Test statistic :

(Phat - P0) ÷ sqrt[(P0(1 - P0)) / n]

1-P0 = 1 - 0.5 = 0.5

(0.53 - 0.5) ÷ sqrt[(0.5*0.5)/1012]

0.03 ÷ 0.0157173

= 1.9087

Pvalue :

Using the Pvalue from test statistic :

Pvalue = 0.02815

To test if result is significant :

α = 0.05

0.02815 < 0.05

Pvalue < α ; Hence, result is significant at α=0.05; Hence, we reject H0.
