Answer:

$60 was the price of Zoe's dinner, before sales tax and tip.

Step-by-step explanation:

Sales tax + tips for dinner = 18.60

The sales tax rate is 11%, and she tipped 20%. Given that the sales tax does not apply to the tip, and the tip is based on the price of the dinner before sales tax. Let x be the original price

Sales tax = 11% * original price = 0.11 * x= 0.11x

Tips for dinner = 20% * original price = 0.20 * x = 0.2x

We know Sales tax + tips for dinner = 18.60

0.11x + 0.2x = 18.60

0.31x = 18.60

Divide by 0.31 on both sides

x = 60

Answer:

Zoe paid $18.60 in sales tax and tips for her dinner

Sales tax + tips for dinner = 18.60

The sales tax rate is 11%, and she tipped 20%. Given that the sales tax does not apply to the tip, and the tip is based on the price of the dinner before sales tax.

Let x be the original price

Sales tax = 11% * original price = 0.11 * x= 0.11x

Tips for dinner = 20% * original price = 0.20 * x = 0.2x

We know Sales tax + tips for dinner = 18.60

0.11x + 0.2x = 18.60

0.31x = 18.60

Divide by 0.31 on both sides

x = 60

following frequency distribution shows the daily expenditure on milk of 30 households in a locality:Daily expenditure on milk(in

valina [46]

Note: As you missed to identify what we have to find in this question. But, after a little research, I am able to find that we had to find the Mode for the data given in your question. So, I am assuming we have to calculate the the Mode. Hopefully, it would clear your concept regarding this topic.

Answer:

The mode of the data = 75

Step-by-step explanation:

Lets visualize the given data in a table to show the frequency distribution:

Daily expenditure on milk (in Rs) Number of households

0-30 5

30-60 6

60-90 9

90-120 6

120-150 4

Here the maximum frequency is 9.

So, modal class is 60-90.

As the formula to calculate the mode:

$Mode = l_{1} + h (\frac{f_{1}-f_{0}}{2f_{1}-f_{0}-f_{2}} )$

Here, the maximum

$l_{1} =60, f_{1} =9, f_{0}=6, f_{0}=6, h=30$

$l=$ is the lower limit of the class

$f_{1} =$ is the frequency of the modal class

$f_{0} =$ is the frequency of the previous modal class

$f_{2} =$ is the frequency of the next previous modal class

$l=$ is the class size

So,

$Mode = l_{1} + h (\frac{f_{1}-f_{0}}{2f_{1}-f_{0}-f_{2}} )$

$Mode = 60 + 30 (\frac{9-6}{2(9)-6-6} )$

$Mode = 60 + \frac{(30)(3)}{6}$

$Mode = 60 + 15=75$

∴ The mode of the data = 75

(4,?) is on the line below. Find the other half of the coordinate. y=3/4x+3. Solve

Nikitich [7]

Answer:

y = 6

Step-by-step explanation:

Given

y = $\frac{3}{4}$ x + 3 and (4, ? )

Substitute the x- coordinate x = 4 into the equation for corresponding value of the y- coordinate.

x = 4 : y = $\frac{3}{4}$ × 4 + 3 = 3 + 3 = 6

Hence the coordinate point is (4, 6)
