I NEED HELP ASAP!!!!!!!!!!!!!!!!!!!!

Answer:

When an expression can be viewed as the difference of two perfect squares, i.e. a²-b², then we can factor it as (a+b)(a-b). For example, x²-25 can be factored as (x+5)(x-5). This method is based on the pattern (a+b)(a-b)=a²-b², which can be verified by expanding the parentheses in (a+b)(a-b).

Answer:

0.79

Step-by-step explanation:

add up the probability that is less than or equal to  0, which is 0.17+0.13+0.33+0.16 = 0.79

The probability [tex]$x \leq0$[/tex]. is 0.79.

What is probability distribution?

A probability distribution exists a statistical function that defines all the possible values and likelihoods that a random variable can consider within a provided range.

The probability distribution is given in the table.

Probability that [tex]$x \leq0[/tex]

The values that are 0 or lower are -3, -2 and -5. So

[tex]$P(X \leq0)=P(X=-3)+P(X=-2)$$[/tex]

From the table:

[tex]$&P(X=-3)=0.13, P(X=-5)=0.17, P(X=-2)=0.33[/tex] and [tex]P(X=0)=0.16[/tex]  

So, [tex]$&P(X \leq-3)=P(X=0)+ P(X=-3)+P(X=-5)+P(X=-2)[/tex]

= 0.16 + 0.13 + 0.17 + 0.33

= 0.79

0.79 probability that [tex]$x \leq0$[/tex].

Answer:

8.31

Step-by-step explanation:

Using the Pythagorean Theorem:

[tex]a^2+b^2=c^2[/tex]

[tex]10^2+b^2=13^2[/tex]

[tex]100+b^2=169[/tex]

[tex]b^2=69[/tex]

[tex]b = \sqrt{69}[/tex]

[tex]b = 8.306623863[/tex]

The side length for [tex]x[/tex], rounded to the nearest hundredths, would be 8.31.

Answer:

[tex]x=\frac{e^{2.5}-3}{5}[/tex]

Step-by-step explanation:

Let y = 5x + 3
Then we get
㏑(y) = 2.5

Using exponentiation,

[tex]e^{lny} = e^{2.5}\\\textrm{But }e^{lny} \textrm{ is simply y (log rule)}\\\textrm{So we get}\\y = e^{2.5}\\\\\\\textrm{Substituting for y we get}\\\\5x + 3 = e^{2.5}\\x = (e^{2.5} - 3)/5\\[/tex]

This works out to x = 1.83649879

Answer:

2/13

Step-by-step explanation:

Answer:

2/13

Step-by-step explanation:

Answer:

1) 5 : 7 : 8.75

2) Happy = 168 .    Juma = 210

3) Rima = 17800 .     Happy = 24920 .    Juma = 31150

Step-by-step explanation:

1) 5 : 7 : 8.75

Ratio Rima to Happy = 5:7

Ratio Happy to Juma = 4:5

7/4 = 1.75

1.75 x 5 = 8.75

Ratio = 5 : 7 : 8.75

2) Happy = 168 .     Juma = 210

Ratio = 5 : 7 : 8.5

120 / 5 = 24

Happy = 24 x 7 = 168

Juma = 24 x 8.75 = 210

3)17800 : 24920 : 31150

5 + 7 + 8.75 = 20.75

73870 / 20.75 = 3560

3560 * 5 = 17800 = Rima

3560 * 7 = 24920 = Happy

3560 * 8.75 = 31150 = Juma

it ends at  16,0)

in the middle it's at between 10 and 16 , so say about 13, where it reaches 27

so in the middle it's (13,27)

so  ( 11, 9)

Answer:

x = 3.2

Step-by-step explanation:

Apply pythagorean theorem, c² = a² + b²

Where,

c is the hypotenuse/longest side = √(10² - 9²) ≈ 4.4

a = x

b = 3

Substitute

4.4² = x² + 3²

19.36 = x² + 9

x² = 19.36 - 9

x² = 10.36

x = √10.36

x = 3.2 (nearest tenth)

Step-by-step explanation:

Step-by-step explanation:

It's asking you what the probablitiy of a red car is.

Since this looks like a test/homework, I'll give some hints.

Let's say that SUV's and car's are x.

Out of x, 60 percent is cars.

Let's call the amount of cars we have y.

Out of y amount car's, 15 percent is red.

It's asking that if you randomely chose a car, what the probability would be if you got a non-red car.

Of course, this problem only needs one variable, but for the sake of simplicity, I added 2.

Hope this helps!
