A sample of automobile dealerships found that 19% of automobiles sold are silver. If two cars are randomly selected, what is the probability that the color of the first car is silver and the color of the second car is also siver?
A. 0.361
B. 0.0361
C. 0.380
D. 0.190

Answer:

a) -1535.5

b) 0

Step-by-step explanation:

A) We do this problem according to its parenthesis. First, let's evaluate the first half, -2[(-1/4)-12(-1)^2]. We have to do (-1)^2 first, because of PEMDAS. (-1)^2 is just 1. Now, our equation is -2[(-1/4)-12*1]. Thus, we get -2[(-1/4)-12] because 12*1 is just 12. Then, we do (-1/4)-12, giving us -12.25. Our equation becomes -2(-12.25). Then, we just get 24.5.

The next half, -5[24+2(-12)^2] is similar. We first evaulate (-12)^2 because of PEMDAS, giving us 144. Then, we have -5[24+2(144)]. 2 times 144 is 288, so we get -5[24+288]. 24 + 288 is 312, so we have -5(312). This finally gives us -1560.

Putting the two together, we get 24.5 - 1560, which is -1535.5.

--------------------------------------------------------------------------------------------------------------B) We substitute a = -1/3 and b = -1 into the equation, -a^2b^2 - 3a^3b^2.

We plug in -1/3 where a is and -1 where b is. So:

-(-1/3)^2(-1)^2 - 3(-1/3)^3(-1)^2.

The tricky part of this problem is making sure you follow PEMDAS. We evaluate the exponents first.

-1/9 * 1  - 3(-1/27) * 1

= -1/9 + 1/9

= 0

Answer:

640

Step-by-step explanation:

y = 40(4)^x

x = 26/13 = 2

y = 40(4)^2

y = 40 (16)

y = 640

Here is your answer :

Answer 1 :

Volume of the Cylinder = πr²h

Therefore, The Volume of the Cylinder is 50.27 Feet

By Rounding, 50 Units/Feet

Answer 2 :

So, volume is always cubed since you have l x w x h.

A cubic ft is 12 in x 12 in x 12 in = 1728 in3.

35328.78/1728 = 20.44  

20.44 x 7.48 = 152.89

About 153 gallons

Answer:

The answer is A!

Step-by-step explanation:

Answer:

207 divided by 14 = 14 remainder 11 so.. none of the answers are right

14x11=154

14x9=126

14x23=322

14x8=112

Step-by-step explanation:

Answer:

12.32 units

Step-by-step explanation:

Use the distance formula to find the lengths between two points:

[tex]d=\sqrt{(x_{2} -x_{1})^2+(y_{2}-y_{1})^2 }[/tex]

the distance between (-2, -1) and (-5,-1) is

[tex]\sqrt{(-2-(-5))^2+(-1-(-1))^2}[/tex]

=[tex]\sqrt{3^2+0^2}[/tex]

=[tex]\sqrt{9}[/tex]

=3

the distance between (-2, -1) and (-3, -4) is

[tex]\sqrt{(-2-(-3))^2+(-1-(-4))^2}[/tex]

=[tex]\sqrt{1^2+3^2}[/tex]

=[tex]\sqrt{10}[/tex]

≈3.16

the distance between (-6, -4) and (-3, -4) is

[tex]\sqrt{(-6-(-3))^2+(-4-(-4))^2}[/tex]

=[tex]\sqrt{(-3)^2+0^2}[/tex]

=[tex]\sqrt{9}[/tex]

=3

the distance between (-6, -4) and (-5, -1) is

[tex]\sqrt{(-6-(-5))^2+(-4-(-1)^2}[/tex]

=[tex]\sqrt{(-1)^2+3^2}[/tex]

=[tex]\sqrt{10}[/tex]

≈3.16

Now, add all the sides:

3+3.16+3+3.16=12.32 units

Note: A property of a parallelogram is that it has two pairs of congruent sides, so for this problem, you could solve for 2 different sides, double them, then add and you will get the same thing.

Answer:

[tex]\frac{1}{2}[/tex]

Step-by-step explanation:

[tex]\frac{27}{32}[/tex] × [tex]\frac{16}{27}[/tex] ← cancel the 27 and 16, 32 by 16

= [tex]\frac{1}{2}[/tex]

Answer:

answer is D

Step-by-step explanation:

as we need to cancel the square in b

so we add square root on both sides and square root of 2.56 is 1.6

Answer:

C and D

Step-by-step explanation:

Given

b² = 2.56 ( take the square root of both sides )

b = ± [tex]\sqrt{2.56}[/tex] = ± 1.6

Then solutions are

b = - 1.6 → C

b = 1.6 → D

5t^2-(3-6t-8t^2)

=5t^2-3+6t+8t^2

=13t2-3+6t

Answer:

[tex]\boxed {\boxed {\sf B. \ 13t^{2} -3+6t}}[/tex]

Step-by-step explanation:

We are given this expression and asked to simplify:

[tex]5t^2-(3-6t-8t^2)[/tex]

First, distribute the -1. Multiply each term in the parentheses by -1 or switch the sign of every term inside the parentheses.

[tex]5t^2+ (-1*3)+(-1*-6t)+(-1*-8t^2)[/tex]

[tex]5t^2+(-3)+(6t)+(8t^2)[/tex]

[tex]5t^2-3+6t+8t^2[/tex]

Next, combine like terms. We see that two terms have a t², so they are like terms. We can add them together.

[tex](5t^2+8t^2)-3+6t[/tex]

[tex]13t^2-3+6t[/tex]

The simplified expression is 13t²-3+6t and Choice B is correct.
