What was the total cost of the 4 litres of paint they used?

Answer:

21/8 or 2 5/8

Step-by-step explanation:

7/2 miles is equal to 3 1/2 mile trail, or also a 3 2/4 mile trail. You then multiply 3 2/4 and 3/4 and get 2 5/8 or 21/8.

The mean of the sampling proportion is 0.03 and the standard deviation of the sampling proportion is 0.008 if the probability that a student forgets to bring their ID with them when they take their SAT is 3%. and a random sample of 500 students was selected.

It is defined as the measure of data disbursement, It gives an idea about how much is the data spread out.

We have:

p = 0.03

n = 500 students

[tex]\rm {\hat p} - Normal[/tex]

So the mean:

[tex]\rm \mu _\hat p \ = \ p \ = \ 0.03[/tex]

For standard deviation:

[tex]\rm \sigma_p = \sqrt{\frac{pq}{m} }[/tex]

q = 1 - p = 1 - 0.03 = 0.97

[tex]\rm \sigma_p = \sqrt{\frac{0.03\times 0.97}{500} }[/tex]

[tex]\rm \sigma_p = 0.008[/tex]

Thus, the mean of the sampling proportion is 0.03 and the standard deviation of the sampling proportion is 0.008 if the probability that a student forgets to bring their ID with them when they take their SAT is 3%. and a random sample of 500 students was selected.

Answer:

Step-by-step explanation:

Like terms have same variable with same power. Combine the like terms. Add / subtract the coeffiecient of the like terms.

9x² and 9x² are like terms

-8 and 3 are like terms.

9x² - 8 + 9x² + 9x + 3 = 9x² + 9x² +9x - 8 + 3

                                   = 18x² + 9x - 5

Answer:

x = 27°

Step-by-step explanation:

[tex]m < 2 = 2\% \times 180 \\ = 36 \\ \\ m < 2 = 65\% \times 180 \\ = 117 \\ \\ [/tex]

Now,

[tex]x = 180 - (36 + 117) \\ \\ x = 180 - 153 \\ \\ x = 27[/tex]

Answer:

Below in bold.

Step-by-step explanation:

a) we need the grestest common factor of  theses values

153 = 3 * 3 * 17

255 =  3 * 5*17

357 = 3 * 7 * 17

The GCF = 3 * 17 = 51.

a) the least possible number of children  is 3.

b) The maximum number is 51 ( as 51 is the GCF of the given values).

c) the least possible number of fruits is when  b)  occurs, that is:

153/51, 255/51 and 357/51

= 3 apples , 5 oranges and 7 pears.

d) the maximum number of fruits is :

153/3, 255/3 and 357/3

= 51 apples , 85 oranges and 119 pears.

Answer:

a) 3 children

b) 51 children

c) 3 apples, 5 oranges and 7 pears

d) 51 apples, 85 oranges and 119 pears

Step-by-step explanation:

lnc - Least possible number of children in group

mnc - maximum possible number of children in group

a - Apples

o - Oranges

p - Pears

a = 153

o = 255

p = 357

a)

To solve this, find the highest divisor for the apples, oranges and pears.

[tex]a = \frac{153}{51} [/tex]

[tex]a = 3[/tex]

[tex]o = \frac{255}{85} [/tex]

[tex]o = 3[/tex]

[tex]p = \frac{357}{119} [/tex]

[tex]p = 3[/tex]

In order for each child to get 51 apples, 85 oranges and 119 pears, there would need to be a minimum of 3 children in the group.

[tex]lnc \: = 3[/tex]

b)

To solve this, find the lowest divisor for the apples, oranges and pears.

[tex]a = \frac{153}{3} [/tex]

[tex]a = 51[/tex]

[tex]o = \frac{255}{5} [/tex]

[tex]o = 51[/tex]

[tex]p = \frac{357}{7} [/tex]

[tex]p = 51[/tex]

In order for each child to get 3 apples, 5 oranges and 7 pears, there would need to be a maximum of 51 children in the group.

[tex]mnc = 51[/tex]

c)

In a group of 51, each child will get:

- 3 apples

- 5 oranges

- 7 pears

d)

In a group of 3, each child will get

- 51 apples

- 85 oranges

- 119 pears

The function which has zeros at x = 10 and x = 2 is [tex]\rm f(x)=x^2-12x+20[/tex].

The zero of a function is any replacement for the variable that will produce an answer of zero.

Graphically, the real zero of a function is where the function's graph crosses the x-axis; that is, the real zero of a function is the x-intercept (s) of the function's graph.

The function which has zeros at x = 10 and x = 2 is;

[tex]\rm f(x)=(x-10)(x-2)\\\\f(x)=x(x-2)-10(x-2)\\\\f(x)= x^2-2x-10x+20\\\\f(x)=x^2-12x+20[/tex]

Hence, the function which has zeros at x = 10 and x = 2 is [tex]\rm f(x)=x^2-12x+20[/tex].

Answer:

Consumer rights and consumer protection law provides a way for individuals to fight back against abusive business practices. These laws are designed to hold sellers of goods and services accountable when they seek to profit by taking advantage of a consumer's lack of information or bargaining power.

Step-by-step explanation:

Individuals can use consumer rights and consumer protection laws to fight back against unfair company practices.

Consumer rights refer to a corpus of legislation that governs what manufacturers of goods must do to safeguard their consumers from damage.

These statutes arose from a succession of court battles, and they have been influenced by the outcomes of those battles.

These rules are intended to hold retailers and service providers responsible when they seek to benefit from a consumer's lack of knowledge or bargaining power.

Answer:

p > 8

Step-by-step explanation:

8p - 48 > 4p - 16

plus 48 on both sides

8p > 4p + 32

minus 4p on both sides

4p > 32

divide 4 on both sides, 32 ÷ 4 = 8, so,

p>8

Answer:

P > 8 ??? I don't know if this is right and if its not then sorry lol

Step-by-step explanation:

Multiply 8(p-6) and 4(p-4)

You will get 8p - 48 > 4p - 16

Then add 48 to -16

Then you will get 8p > 4p + 32

Then subtract 4p from 8p

Then you will get 4p > 32

Then divide 4 from 4p and 32

Then you will get p > 8

Answer:

1 in 999 i guess

Step-by-step explanation:

The linear cost function of the computer shop in this scenario will be C(x) = 649x + 1500.

From the information, the linear cost function is C(x) = 649x + 1500 and the linear revenue function will be R(x) = 899x.

The cost of selling 37 computers will be:

C(x) = 649x + 1500

C(x) = 649(37) + 1500

C = 25513

The revenue from selling 37 computers will be:

R(x) = 899x.

R = 899(37)

R = 33263

The breakeven point will be:

649x + 1500 = 899x

899x - 649x = 1500.

250x = 1500

x = 1500/250

x = 6

$172.80

Step-by-step explanation:

The phone cost $800

Decreases by 2/5 every year. So the cost would be 3/5 (instead of doing 800 - 800 *2/5 its easier to just do 800*3/5)

Here is a equation for this question:

[tex]800* (\frac{3}{5})^{t}[/tex]

t = time in years

So we can plug in 3 for t
