The next day the manager finds only 8 of the 200 randomly selected clocks are defective. About how many clocks out of the 10,000 produced that day are probably defective?

Answer:

Michaela gets 3.45$ back.

Step-by-step explanation:

1 carton of eggs = 1.58$

she buys 2, so 2 times 1.58= 3.16$

1 pound of turkey = 6.99$

she buys 4.15 pounds, so 4.15 times 6.99= 29.01$

she buys a jar of jam for 4.38$

4.38 + 3.16 + 29.01 = 36.55$

4 times 10= 40

40 - 36.55 = 3.45$

Answer:

  $3.10

Step-by-step explanation:

The cost of the goods Michaela buys is ...

  2 cartons eggs at $1.58 per carton = $3.16

  4 1/5 pounds turkey at $6.99 per pound = $29.36

  1 jar of jam at $4.38 per jar = $4.38

The total is then ...

  $3.16 +29.36 +4.38 = $36.90

Four $10 bills will be $40, so the change is ...

  $40 -36.90 = $3.10

Michaela will receive $3.10 in change.

Additional comment

We know that Brainly often mangles mixed numbers, so we have assumed that "415" is intended to be 4 1/5. If it is intended to be 4.15 pounds, then the price of the turkey, and the change, will be different by about $0.35. Michaela's change will increase by that amount.

Answer:

ok so lets find the difference on the table

from 5 to 8 is goes up 250.5(668-417.5)

so that means 3 tickets goes 250.5 so lets divide by 3

250.5 divide by 3=83.5 per ticket

83.5*6=501

501

Hope This Helps!!!

Answer:

Equation : $83.50x = Cost of the tickets

(where x = number of tickets)

Cost of 6 tickets : $501

Step-by-step explanation:

I'm not sure if this is the way they want you to do it, but what I did is :

1) Solve a proportion to figure out the cost of 1 ticket

5/417.50 = 1/x

5x = 417.50(1)

5x/5 = 417.50/5

x = 83.50

So, the cost of 1 ticket is $83.50

2) Create an equation

If x equals the number of tickets :

83.50x = Cost of the tickets

3) Solve for 6 tickets

83.50(6) = Cost of the tickets

501 = Cost of the tickets

Substitute x for the number of tickets, which is 6 and you'll get $501 :)

Answer:

30%

Step-by-step explanation:

Purchases:

Coat £20

Hat £15

Gloves for £5

Total amount of purchases: £20 + £15 + £5 = £40

Sales:

Coat at 50% profit: 150% × £20 = 1.5 × £20 = £30

Hat: £18

Gloves at a 20% loss: 80% of £5 = £4

Total amount of sales: £30 + £18 + £4 = £52

Amount of profit: £52 - £40 = £12

Percent of profit: £12 / £40 × 100% = 30%

Answer:

$2.25

Step-by-step explanation:

last year price = $3.00

this year price = $3.00 - (25% × $3.00)

= $3.00 - $0.75

= $2.25

Answer: 9sqrt(3)

Step-by-step explanation:

First, we can prime factorize 243.

243 = 3^5

Therefore we are computing the square root of 3^5

3^5 = 3^4 * 3^1; 3^4 = (3^2)^2

Therefore, sqrt(3^5) = sqrt((3^2)^2))*3^1)

= 3^2*sqrt(3)

= 9sqrt(3)

Answer:

Step-by-step explanation:

Using sampling concepts, it is found that the sampled is biased because only parents who attend the school's musical show are surveyed, hence they are not very likely to support the decrease, and the population proportion should be greater than the one found in the show.

Samples may be classified as:

A sample has to take into account all aspects of the population, otherwise it is biased. In this problem, either people support the decrease, or they do not. Only people that went to the show were surveyed, that is, people who are unlikely to support the decrease, which generates bias, as the population proportion should be greater than the one found in the show.

Answer:

105% ?

Step-by-step explanation:

I'm not entirely sure if the 1 yard 'squared' is considered in the 30% but assuming it's not ... 1yd =30% 1yd^2=60% and 2yd=45% so 60%+45%=100%

-5a²+13ab should be subtracted.

Based on the given conditions, formulate,

[tex]→- {a}^{2} - 4 {a}^{2} + 13ab[/tex]

[tex]→-({a}^{2} - 4 {a}^{2}) + 13ab[/tex]

Taking the coefficients or numbers, we get,

[tex]→(- 1 - 4) {a}^{2} + 13ab[/tex]

[tex]→ - 5 {a}^{2} + 13ab[/tex]

Given :

What should be subtracted from a² – 7ab + 3b² to get – 4a² + 6ab + 3b² ?

Solution :

Let the required expression to be subtracted be x

⇢ a² – 7ab + 3b² – x = – 4a² + 6ab + 3b²

⇢ a² – 7ab + 3b² – (– 4a² + 6ab + 3b²) = x

⇢ a² – 7ab + 3b² + 4a² – 6ab – 3b² = x

Combining the like terms :

⇢ a² + 4a² – 7ab – 6ab + 3b² – 3b² = x

⇢ 5a² – 13ab = x

⇢ x = 5a² – 13ab

Therefore,

5a² – 13ab should be subtracted from a² – 7ab + 3b² to get – 4a² + 6ab + 3b².

The dilation which represented by the line is enlargement and the scale factor of dilation is 2.

Dilation of a figure, means the transformation of the figure. The factor by which the given figure dilated, called the scale factor of dilation.

The distance from O to A is 3. Therefore,

[tex]OA=3[/tex]

The distance from A to A prime is 3. Therefore,

[tex]AA'=3[/tex]

Here, the new length of the line segment is,

Answer:

3 solutions

Step-by-step explanation:

x = 0; x = 2; x = -6

As we are given with an equation as follows :

[tex]{:\implies \quad \sf x^{2}(x+2)(x+6)=0}[/tex]

As product of these three factors is equal . So , any of these factor can be 0 as product is 0 only when one of the expressions which are multiplied is 0. So , 3 cases arises as follows ;

[tex]{:\implies \quad \sf x^{2}=0}[/tex]

On raising ½ power to both sides we have ;

[tex]{:\implies \quad \sf x=\pm \: 0}[/tex]

Now , as +0 and -0 have no difference in them . So , it's simply 0

[tex]{:\implies \quad \sf So\quad x=0}[/tex]

[tex]{:\implies \quad \sf x+2=0}[/tex]

[tex]{:\implies \quad \sf So\quad x=-2}[/tex]

Answer:

a=10 and c=20

Step-by-step explanation:

This is a system of equations. I will solve using the substitution method.

a+c=30

12a+8c=280

Solving for a:

a+c-c=30-c

a=30-c

Substituting a into the second equation:

12(30-c)+8c=280

360-12c+8c=280

360-4c=280

-4c=-80

c=20

Substituting into the original equation:

a+20=30

a+20-20=30-20

a=10

To prove this answer is correct, I will plug the solutions back in to the original equation.

a+c=30

10+20=30

30=30, True

12a+8c=280

12*10+8*20=280

120+160=280

280=280, True

Therefore, a=10 and c=20.
