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:

Step-by-step explanation:

From the given information:

We are to find the following:

1)

Directional hypothesis: The directional hypothesis is the groups with different bedroom lightning conditions having a different proportion of eyesight proportions.

2)

The non directional hypothesis is each group having the same proportion of eyesight problems regardless and independent of the condition of the bedroom lightning.

3)

Control group: Children that slept in darkness

4)

Experimental groups: Children that slept in night light and those that slept with lamp.

5)

Independent variable: Light condition of the bedroom

Dependent variable: Eye sight problem.

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:

2 = 18, 3 = 73

Step-by-step explanation:

2) 22+140= 162

180-162= 18

x=18

(180 ‘cuz that’s the full angle of a triangle)

——————————————————————

3) the right angle is a 90 degree angle so

17+90=107

180-107=73

x=73

[tex]P(3) = 0.3397[/tex]

Step-by-step explanation:

The given details represent binomial distribution. So, we have:

[tex]n = 5[/tex]

[tex]p = 64\% = 0.64[/tex]

Required

Calculate P(3)

This is calculated using:

[tex]P(x) = ^nC_x * p^x * (1- p)^{n-x}[/tex]

This gives:

[tex]P(3) = ^5C_3 * 0.64^3 * (1- 0.64)^{5-3}[/tex]

[tex]P(3) = 10 * 0.64^3 * 0.36^2[/tex]

[tex]P(3) = 0.3397[/tex]

Answer:

Undefined.

Step-by-step explanation:

Slope is equal to the change in y over the change is x, or rise over run.

[tex]m=\frac{change in y }{ change in x}[/tex]

The change in x is equal to the difference in x-coordinates, and the chnage in y is equal to the difference in y-coordinates.

[tex]m=\frac{y2-y1}{x2-x1}[/tex]

Substitute in the values of x and y into the equation to find the slope.

[tex]m= \frac{-2-(2)}{2-(2)}[/tex]

Simplify it. since -2-(2) and 2-(2) = nothing, the Slope is Undefined.

Hence, the slope is Undefined.
