Answer:

Step-by-step explanation:

The absolute error is the difference between the estimate and the actual weight:

  7.0 kg -6.6 kg = 0.4 kg . . . . absolute error

__

The relative error is the ratio of the absolute error to the actual weight:

  (0.4 kg)/(6.6 kg) × 100% = 6.060606...% ≈ 6.1% . . . . relative error

Answer: yes they both have the same answer.

Step-by-step explanation: 12 - 7 equals 4 and 28/7 equals 4

Answer:

yes x is the same in both problems

Step-by-step explanation:

in the first one you subtract seven from both side to leave you with x=5

in the second problem you subtract 14 (2x=10) from both sides then divide both sides by 2 so you are left with x=5

Answer:

y=9/8

Step-by-step explanation:

dont have one

Answer:

y=9/8

Step-by-step explanation:

8(7-4y)=20

8(7)-8(4y)=20

56-32y=20

-32y=-36

y=9/8 or 1.125

Answer:

the actual answer is 75 percent of its price

Step-by-step explanation:

Answer:

75

Step-by-step explanation:

Let the initial cost of oil be x. After the first year, the price of oil is 1.5x. After the second year, the price of oil is 0.5 ∙ 1.5x = 0.75x.

This is 75 percent of its price at the beginning of the first year.

Answer:

8.5

Step-by-step explanation:

since it is the same as ABC, 2x-1=16

add the 1 to both sides which gives you 2x=17

then divide each side by 2 which gives you x=8.5

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

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

have a great day, also can I please be brianliest :)

Answer:

[tex]A^{'}[/tex] = {1,3,5,7,9,....}

[tex]B^{'}[/tex] = {1,2,4,5,7,8,10,11,13,14......}

[tex]C^{'}[/tex] = {1,2,3,4,5}

[tex]D^{'}[/tex] = {10,11,12,13,14,15,......}

Step-by-step explanation:

Solution:

It is given that, Universal set is the set of all Natural Numbers.

and

Set A, Set B, Set  C, Set D are subsets of Universal set.

A = {x:x is even natural numbers} = {2,4,6,8,10,.....}

B = {x:x ∈ N and x is a multiple of 3} = {3,6,9,12,15,....}

C = {x:x∈ N and x < 5} = {6,7,8,9,10,.....}

D = {x:x ∈ N and x > 10} = {1,2,3,4,5,6,7,8,9}

U = {1,2,3,4,5,6,7,8,9,10,11,........}

Complements:

[tex]A^{'}[/tex] = U-A = {1,2,3,4,5,6,7,8,9,10,11,........} - {2,4,6,8,10,.....}

[tex]A^{'}[/tex] = {1,3,5,7,9,....}

[tex]B^{'}[/tex] = U-B =  {1,2,3,4,5,6,7,8,9,10,11,........} - {3,6,9,12,15,....}

[tex]B^{'}[/tex] = {1,2,4,5,7,8,10,11,13,14......}

[tex]C^{'}[/tex] = U-C = {1,2,3,4,5,6,7,8,9,10,11,........} - {6,7,8,9,10,.....}

[tex]C^{'}[/tex] = {1,2,3,4,5}

[tex]D^{'}[/tex] = {1,2,3,4,5,6,7,8,9,10,11,........} - {1,2,3,4,5,6,7,8,9}

[tex]D^{'}[/tex] = {10,11,12,13,14,15,......}

Answer:

The first step would be to plot the y-intercept. In this equation, the y-intercept is 5. The ordered pair is (0, 5), because (x, y).

You go up 5 from the origin (the center of the graph, (0, 0) ), and plant a dot on the y-axis.

Answer:

33% or 4/12

Step-by-step explanation:

There are 5 red, 3 green, and 4 yellow, so make it into a fraction. In total there are 12 marbles(5+3+4). There are 4 yellow marbles, so the fraction would be 4/12. Turn this into a percent to get the probability. 4/12 = 0.33 = 33%

Answer:

B) -19

Step-by-step explanation:

-7 + 2x = -45

+7             +7

2x = -38

/2      /2

x = -19

Answer:

b

Step-by-step explanation:

2x=-45+7

2x=-38

x=-38/2

x=-19

165 votes

So we know that there would be 225 votes.

Explanation:

225 divide 25=11

Then lastly multiply 15 with 11.

Final Result: 165 votes

Answer:

The slope means that every time the x value changes by +1, then the y value will change by +2.

The y-intercept is 3, which means is that when the y value is at 3, the line crosses the y-axis, or x has as value of 0.

For real though, why are there so many questions about slope and intercept, I just finished answering a question like this.
