Find the common difference of the arithmetic sequence shown. 1/4.3/8,1/2

Answer:

[tex]P(X\geq 1)= 1 - 0.0497 8 =0.95022[/tex]            

Step-by-step explanation:

Step(i):-

Let 'X' be the random variable in Poisson distribution

Mean of the Poisson distribution λ or ∝ = 3 per  (cm³)

Given n = 5 samples

[tex]P(X=r) = \frac{e^{-\alpha }\alpha ^{r} }{r!}[/tex]

Step(ii):-

The probability that at least one sample will contain one or more bacterial colonies

P(X≥1)    = 1-P(X< 1)

             = 1 - P( X=0)

[tex]P(X\geq 1)= 1 - \frac{e^{-\alpha }\alpha ^{r} }{r!}[/tex]

[tex]P(X\geq 1)= 1 - \frac{e^{-3 }3 ^{0} }{0!}[/tex]

[tex]P(X\geq 1)= 1 - 0.0497 8 =0.95022[/tex]

Answer:

The value of b is 5 if the parallelogram is a rectangle

Step-by-step explanation:

Mathematically, the diagonals of a rectangle are equal in value

Thus, for the given expressions to represent the diagonals of a rectangle, the two must be equal

To get the value of b that makes the two equal, we simply equate the two expressions

We have this as;

10/12(24b/5 - 36/5) = 2/3 (3b + 6)

opening the brackets, we have;

4b - 6 = 2b + 4

4b - 2b = 4 + 6

2b = 10

b = 10/2

b = 5

Answer:

0

Step-by-step explanation:

xyz(-6-11+17)

xyz(0)

48 points gained in those 3 days.

Subtract 220 with 48, then add 96. Last step would be subtracting 220 with the amount they have now in those 3 days to find how much points the stock market gained in those 3 days.

Subtract 220-48.It‘ll be 172.

Add 172 with 96. 172+96=268.

Subtract 268 with how much points the stock market had 3 days ago. 268-220.

Sot eh stock market gained 48 points in 3 days.

Option (3)

Step-by-step explanation:

[tex]\text{tan}(\frac{\theta}{2})=\text{sin}\theta[/tex]

[tex]\text{tan}(\frac{\theta}{2})=2\text{sin}{\frac{\theta}{2}} \text{cos}(\frac{\theta}{2})[/tex]

[tex]\frac{\text{sin}\frac{\theta}{2}}{\text{cos}\frac{\theta}{2}} =2\text{sin}{\frac{\theta}{2}}\text{cos}(\frac{\theta}{2})[/tex]

[tex]\text{sin\frac{\theta}{2}}=2\text{sin}{\frac{\theta}{2}}\text{cos}^2(\frac{\theta}{2})[/tex][tex]\text{sin\frac{\theta}{2}}=2\text{sin}{\frac{\theta}{2}}\text{cos}^2(\frac{\theta}{2})[/tex][tex]\text{sin}\frac{\theta}{2}=2\text{sin}{(\frac{\theta}{2})}\text{cos}^2(\frac{\theta}{2})[/tex]

[tex]\text{sin}\frac{\theta}{2}-2\text{sin}{(\frac{\theta}{2})}\text{cos}^2(\frac{\theta}{2})=0[/tex]

[tex]\text{sin}\frac{\theta}{2}[1-2\text{cos}^2(\frac{\theta}{2})]=0[/tex]

[tex]\text{sin}\frac{\theta}{2}=0[/tex] ⇒ [tex]\theta=0[/tex]

[tex]1-2\text{cos}^2(\frac{\theta}{2})=0[/tex]

[tex]\text{cos}(\frac{\theta}{2})=\frac{1}{\sqrt{2}}[/tex]

[tex]\frac{\theta}{2}=\frac{\pi}{4}[/tex]

[tex]\theta=\frac{\pi}{2}[/tex]

Therefore, θ = 0 and [tex]\frac{\pi}{2}[/tex] are the solutions.

ANSWER IS 70!

Step-by-step explanation:

Answer:

The answer is 8 purses

Step-by-step explanation:

If we multiply 36 by 8, we get $288. If we multiplied 36 by 8 we must also multiply 10 by 8 because it cost 10 dollars on one purse. So y=10(8)+208, y=288

Answer:

8 is correct.

Answer:

-9x-27+15x=6x-27

.....6x-27.…...

Answer:

D: 6x - 27

Step-by-step explanation:

1. Distribute

2. Combine like terms

3. You will get your final answer

-9(x + 3) = -9x - 27

-9(x) = -9x

-9(3) = -27

-9x - 27 + 15x

-9x and 15x are like terms. So add them

-9x + 15x = 6x

So your final answer is 6x - 27.

Answer:

About 0.12 dollars

Step-by-step explanation:

1.49/12 = 0.12416666666/1

About 0.12 dollars

Answer:

0•1254$ per pencil

Step-by-step explanation:

method 1

12 pencils = 1•49$

1 pencil = X ( unknown)

cross multiply

12x = 1•49$

divide both sides by 12x

X = 0•124$ per pencil

Method 2

you can simply divide the price of the pencils = 1•49$

by the number of pencils bought = 12

1•49/12

= 0•124$

Step-by-step explanation:

Answer: b

Step-by-step explanation:

The value of x is 20.

There are three commonly used trigonometric identities.

Sin x = Perpendicular / Hypotenuse

Cosec = Hypotenuse / Perpendicular

Cos x = Base / Hypotenuse

Sec x = Hypotenuse / Base

Tan x = Perpendicular / Base

Cot x = Base / Perpendicular

We have,

Sin 30 = 10 / x ______(10

We know that,

Sin 30 = 1/2 _____(2)

So,

Substituting (2) in (1).

1/2 = 10/x

x = 10 x 2

x = 20

Thus,

The value of x is 20.
