Answer:

well the highest number you could get in a dice is 6 and the lowest is a 1

6=100%

5=85%

4=65%

3=45%

2=25%

1=5%

so the % chance of you getting a 4 or 5 is around 70%

Answer:

A. (y - 2) = 3/2 ( x + 1)

Explanation:

The point-slope formula is ( y - y1) = m ( x - x1). Just distribute the given where m is 3/2, x1 = - 1 and y1 = 2.

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:

it's b

Step-by-step explanation:

correct on edge!

The equivalent expression is tanx.

We have given that,

tan(x – pi)

We have to determine the expression equivalent to the given expression

tan(x)=sinx/cosx

[tex]=\frac{\sin \left(x\right)}{\cos \left(x\right)}[/tex]

[tex]=\tan \left(x\right)[/tex]

Therefore the equivalent expression is tanx.

Answer:

163 I would think

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.)

Step-by-step explanation:

A complete circle is 360 degrees so we divide 360/45 and that is equal to 8

Answer:

You have an right angle which is like an L and is 90 degrees. A acute angle and it just like if you was to close a L just a little bit you would get an acute angle which is 30 degrees. Last you have the the obtuse angle it´s like is you pulled the top of L and pulled it back a little bit you would get that. I mean those are the basic angles.

Step-by-step explanation:

Answer:

from 3 o’clock until 3:20, the minute hand will move 1/3 of the way around the circle or 120 degrees. But the hour hand has also moved 1/3 of the way to the next number, or 10 degrees.

Answer:

42deg

Step-by-step explanation:

Let's see.

We'll consider 12:00 the "starting position"

The minute hand moves with the speed of 360deg in an hour, so 6deg per minute.

The hour hand moves with the speed of 360deg in 12hours, so 30deg per hour, so 0.5deg per minute.

at 3:24, the minute hand has moved 24*6deg=144deg from the starting position, while the hour hand has moved by 3*30deg + 24*0.5deg = 102deg

The absolute difference of the angles is 144deg-102deg = 42deg and it's the angle between the hands.

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.
