Scott did an experiment in which he flipped a coin 100 times. His coin landed on heads 40 times and tails 60 times. What conclusions could your draw from Scott’s experiment?
Select all that apply:

A. Scott did not do the experiment right.
B. The experimental findings are close to the theoretical probability of 50%.
C. There must have been a mistake in Scott’s data since the experimental probability is not close to the theoretical probability.
D. You cannot draw a conclusion about the experiment unless you do it yourself.
E. If Scott performed more trials and flipped the coin 1000 times, the experimental probability would be expected to be closer to the theoretical probability of 50%

Answer:

a) The addition property of equality

b) The division property of equality

Step-by-step explanation:

Here, we want to know the correct step to use

From the given question, to proceed;

All we have to do is to move the value that has a negative value on the left hand side to the right hand side

what accompanies this is the addition of the both terms, on the right hand side

After this, we now proceed to divide the sum by the coefficient of x

Thus, the correct choices are;

a) The addition property of equality

b) The division property of equality

Answer:

x = 3 and y = 8

Step-by-step explanation:

The Opposite sides of a parallelogram are equal and parallel. It means,

[tex]\dfrac{y}{2}=4\\\\y=8[/tex]

Also,

5x - 6 = 3x

Taking like terms together,

5x -3x = 6

2x = 6

x = 3

So, the values of x and y are 3 and 8 respectively.

The method of completing the squares method will be used for the next step. The next step would be ( x+ (b/2a)  )^2 = -c/a + b^2/(4a^2)

Suppose that two terms are 'a' and 'b'.

Then, their sum's square is expanded as:

[tex](a+b)^2 = a^2 + 2ab + b^2[/tex]

For this case, we're given the quadratic equation with its 4 steps of solution as:

[tex]ax^2 + bx + c = 0\\\\\dfrac{ax^2}{a} + \dfrac{bx}{a} + \dfrac{c}{a} = 0\\\\x^2 + \dfrac{bx}{a} + \dfrac{c}{a} = 0\\\\x^2 + \dfrac{bx}{a} = -\dfrac{c}{a}\\\\x^2 + \dfrac{bx}{a} + \dfrac{b^2}{4a^2} = -\dfrac{c}{a} + \dfrac{b^2}{4a^2}[/tex]

We've to proceed to the next step.

In the left hand side, we can use the formula [tex](a+b)^2 = a^2 + 2ab + b^2[/tex], where [tex]\rm a \: is \: x^2, and \: b \: is \: \dfrac{b}{2a}[/tex]

Thus, we have:

[tex]x^2 + \dfrac{bx}{a} + \dfrac{b^2}{4a^2} = x^2 + 2 \times x \times \dfrac{b}{2a} + \left(\dfrac{b}{2a} \right)^2 = \left( x + \dfrac{b}{2a} \right)^2[/tex]

We expressed the left sided expression in this form so that the variable 'x' (which is assuminly the only variable in the equation, whose value is to be known) gets packed into single container and not spread throughout with different powers.

Now, we can use square root and then subtraction and division of some terms which will make 'x' stay on one side of the equation, and rest of the constants on other side, as the value of 'x' for which the considered equation [tex]ax^2 + bx + c = 0[/tex] is correct.

The next step of the solution, therefore, is:

[tex]\left( x + \dfrac{b}{2a} \right)^2 = \dfrac{-c}{a} + \dfrac{b^2}{4a^2}[/tex]

Using t and c as variables, we get

100c + 400t ≥ 5400

Simplified,

100(c + 4t) ≥ 5400

c + 4t ≥ 54

To find the minimum number of chairs that need to be sold, we evaluate using t = 0

c + 4(0) ≥ 54

c ≥ 54

To find the minimum number of tables that need to be sold, we evaluate using c = 0

(0) + 4t ≥ 54

4t ≥ 54

t ≥ 13.5 Since we can't purchase half a chair, we round up our result giving us t ≥ 14

Answer:

8/10 * 3 = (8*3)/10 = 24/10 = 2.4 miles

Step-by-step explanation:

The question is incomplete. The complete question is :

George, Matthew and Isabelle invest money in a savings account, which pays compound interest of 3% p.a.

a). George invested £ 4800. Work out the total value of his investment after 5 years.

Solution :

It is given that :

George invested amount of, P = £ 4800

Time of investment, t = 5 years

Rate of interest, r = 3 % p. a.

The total value will be :

[tex]$A=P(1+\frac{r}{100})^t$[/tex]

[tex]$A=4800(1+\frac{3}{100})^5$[/tex]

[tex]$A=4800\times (1.03)^5$[/tex]

[tex]A = 4800 \times 1.1592[/tex]

   = 5564.16

Therefore the total value after 5 years = £ 5564.16
