Milly has a equal number of 20p coins and 50p coins . The value of her 20p coins is £2.80 . Work out the total value of her 20p and 50p coins

Answer:

Total paint left over = [tex]\frac{13}{12}L[/tex]

Step-by-step explanation:

Given - To paint a house, 5/4 L of white paint and 1/2 L of blue paint

             were mixed. In the end only 2/3 L of the mixture were used.

To find - How many liters of paint were left over ?

Proof -

Given that,

5/4 L of white paint and 1/2 L of blue paint were mixed.

So, total mixture = [tex](\frac{5}{4} + \frac{1}{2})L[/tex]

                          = [tex]\frac{5 + 2}{4}L[/tex]

                          = [tex]\frac{7}{4}L[/tex]

⇒Total mixture =  [tex]\frac{7}{4}L[/tex]

Now,

Given that ,

In the end only 2/3 L of the mixture were used.

So, total mixture left = [tex](\frac{7}{4} - \frac{2}{3})L[/tex]

                                = [tex]\frac{21 - 8}{12}L[/tex]

                                = [tex]\frac{13}{12}L[/tex]

∴ we get

Total paint left over = [tex]\frac{13}{12}L[/tex]

Answer:54.117

Step-by-step explanation:

Mean=45.4

Standard deviation=5.3

=5%. =0.05

1-0.05=0.95

Normal Dist(40,10)

InverseCdf(0.95,45.4,5.3)

The demand that has a 5% probability of being exceeded is equal to 54.117.

We have given that,

A baker knows that the daily demand for mango pies is a random variable that follows the normal distribution with a mean of 45.4 pies and a standard deviation of 5.3 pies.

We have to determine the

demand that has a 5% probability of being exceeded. Use a TI-83, TI-83 plus, or TI-84 calculator.

Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.

Mean=45.4

Standard deviation=5.3

Answer:

2

Step-by-step explanation:

2/3 times 4 sets is 8/3, which simplifies to 2 1/3. but you cant have 1/3 of a package so you round to 2

Step-by-step explanation:

The first expression is :

[tex]-11\times \dfrac{2}{3}[/tex]

Numerator = -11×2 = -22

Denominator = 3

So, answer will be :

[tex]-11\times \dfrac{2}{3}=\dfrac{-22}{3}[/tex] (negative)

The second expression is:

[tex]-11\times \dfrac{-2}{3}[/tex]

Numerator = -11×-2 = 22

Denominator = 3

So, the answer will be :

[tex]-11\times \dfrac{-2}{3}=\dfrac{22}{3}[/tex] (positive)

Hence, this is the required solution.

Answer:

y=3x+12

y-12=3x

x=y/3 - 4

f(y)=y/3 - 4

or

f(x)=x/3 - 4

where f(x) is the inverse of y.

Hope this helps ;]

Step-by-step explanation:

Applying Euler's method:

Let f(x, y) = 2x - 3y + 1, and consider the following recurrence relations:

[tex]\begin{cases}x_0=1\\x_n=x_{n-1}+h&\text{for }n\ge1\end{cases}[/tex]

[tex]\begin{cases}y_0=5\\y_n=y_{n-1}+f(x_n,y_n)h&\text{for }n\ge1\end{cases}[/tex]

For step size h = 0.1, we can approximate y (1.2) with just 2 steps:

[tex]\begin{cases}x_0=1\\y_0=5\end{cases}\implies y_1=5+f(1,5)\times0.1=3.8[/tex]

[tex]\begin{cases}x_1=1+0.1=1.1\\y_1=3.8\end{cases}\implies y_2=3.8+f(1.1,3.8)\times0.1=\boxed{2.98}[/tex]

For step size h = 0.05, we need 4 steps:

[tex]\begin{cases}x_0=1\\y_0=5\end{cases}\implies y_1=5+f(1,5)\times0.05=4.4[/tex]

[tex]\begin{cases}x_1=1+0.05=1.05\\y_1=4.4\end{cases}\implies y_2=4.4+f(1.05,4.4)\times0.05=3.895[/tex]

[tex]\begin{cases}x_2=1.05+0.05=1.1\\y_2=3.895\end{cases}\implies y_3=3.895+f(1.1,3.895)\times0.05=3.47075[/tex]

[tex]\begin{cases}x_3=1.1+0.05=1.15\\y_3=3.47075\end{cases}\implies y_4=3.47075+f(1.15,3.47075)\times0.05\approx\boxed{3.1151375}[/tex]

(Compare these to the value of y (1.2) found using the exact solution to the differential equation, about 3.22832.)

Answer:

9/4

Step-by-step explanation:

0.25 is one fourth and if you convert the whole number into fourths and add the one fourth from the decimal it is 9/4

Answer:

9/4

Step-by-step explanation:

First ever need to make this decimal a fraction.

Convert decimal to fraction

2.25 = 225/100

Now we need to simplify.

225/25=9

100/25=4

9/4 or 2 1/4

Answer:

Step-by-step explanation:

Answer:

Step-by-step explanation:

It's linear.

First of all, let's recreate the table.

The equa ttion is something like

y = a x

Now if x = - 9

and y = - 157 / 3

Then a = -157/ (-9*3)

a = 5.814814814....

y = 5.814814 (-8)

y = - 46.5185185....

y = -139/3 = -46.333333333 the difference is in how this was rounded.

y = 5.814814  * -7 = 40.703703703...

y = -121/3 = -40.333333 Again another rounding problem.

I'm sure if you try the rest of them, they will do the same thing.

The scenarios in which the statistics are misleading; option 1 and 3.

A portion of population taken and analyzed to predict information about population is called sample of that population.

Ex: When someone surveys a group, then he/she surveys a portion and not whole population in general.

Those numbers who summarize information about sample are called statistic.

Step-by-step explanation:

By Themba you write 28/100 because a percentage means 100 ,you 100 by 28 and then your common fraction answer will be 7/25 in a decimal way it is 0,28 .

Jamal is 0,3 which is 0,3 means 3/10 and Alison 1/8 and the answer for Alison is 0,125 or in a common fraction way it is 125/10.

And then you add all the answers and you get 141/200 .

And then 500-7/25-3/10-0,125 and then you get 499,295, and 499,295÷100 =4,99 which is 4,99%.
