12. D(-5.-6), E(5.2), 7(4.-4). G(-6, -12) (Distance & Slope Formulas)

Answer:

4

Step-by-step explanation:

10/100=0.1

1% = 0.1

0.1*40= 4

Answer:

angle 1= 30 degrees

angle 2= 120 degrees

angle 3= 30 degrees

Step-by-step explanation:

A triangle is equal to 180 degrees so first step is to subtract 120 to get the total of your two missing angles

180-120=60

and since your two missing angles are equal to each other you can divide by 2 and you get your two missing angles

60 / 2 = 30

Answer:

The slope of the line is [tex]\frac{5}{2}[/tex]

Step-by-step explanation:

Hi there!

We are given the following points: (-2, 4) and (0, 9)

We want to find the slope (m) of these 2 lines, and the problem asks us to use the slope formula

The slope formula is given as [tex]\frac{y_2-y_1}{x_2-x_1}[/tex], where [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] are points

We have everything we need to calculate the slope, but let's label the values of the points to avoid any confusion.

[tex]x_1=-2\\y_1=4\\x_2=0\\y_2=9[/tex]

Now substitute these values into the formula to find the slope.

m=[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

m=[tex]\frac{9-4}{0--2}[/tex]

Simplify.

m=[tex]\frac{9-4}{0+2}[/tex]

Add (or subtract) the numbers together

m=[tex]\frac{5}{2}[/tex]

The slope of the line is [tex]\frac{5}{2}[/tex]

Hope this helps!

Answer:

x = 19.25

Step-by-step explanation:

The diagonal of a rhombus bisects opposite angles and opposite angles are congruent.  

So, 2x - 1 is the measure of the third angle of the triangle

Therefore, 2x - 1 + 2x - 1 + 4x + 28 = 180 since the sum of the measures of the angles of a triangle is 180

8x + 26 = 180

8x = 154

x = 19.25

Answer: The probability of getting a prime number exactly five times = 0.1908

Step-by-step explanation:

Prime numbers from 1 to 30 are 2,3,5,7,11, 13, 17, 19, 23, 29.

The probability of getting a prime number p= [tex]\dfrac{10}{30}=\dfrac13[/tex]

Number of trials n = 12

Binomial probability formula:

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

, where x= number of successes

n= number of trials.

x = Number of successes

p= probability of getting one success.

The probability of getting a prime number exactly five times:

[tex]P(X=5)=\ ^{12}C_5(\frac13)^5(1-\frac13)^{7}[/tex]

[tex]=\frac{12!}{5!7!}(\frac1{243})(\frac{128}{2187})\\\\=0.1908[/tex]

Hence, the probability of getting a prime number exactly five times = 0.1908
