miss Akunina [59]2 years ago

Answer:

X ~ B(n, p)

Given: X ~ B(2, 5/17)

⇒  n = 2

⇒  p = 5/17

Binomial distribution formula:

\sf P(X = x) = nC_x (1-p)^{(n-x)}p^x

As n = 2, calculate P(X = 0), P(X = 1) and P(X = 2):

\sf P(X = 0) = 2C0 (\frac{12}{17})^{(2-0)}(\frac{5}{17})^0=\dfrac{144}{289}}

\sf P(X = 1) = 2C1 (\frac{12}{17})^{(2-1)}(\frac{5}{17})^1=\dfrac{120}{289}}

\sf P(X = 2) = 2C2 (\frac{12}{17})^{(2-2)}(\frac{5}{17})^2=\dfrac{25}{289}}

13) The product is a name for the answer to a multiplication question.
6.65*10,000
=66500 (the decimal point moved 4 places to the right (you're multiplying) since they're 4 zeros in 10,00)

15) The quotient is a name for the answer to a division question.
2.374/100
=0.02374 ( the decimal point moved 2 places to the left ( you're dividing) since they're 2 zeros in 100)

Hope this helps! A thanks/brainiest answer would be appreciated :)

- 5 .5 ( d - 2 ) = - 12. 1
OverLord2011 [107]

Answer:

D = 4.2

Step-by-step explanation:

-5.5 ( d - 2 ) = - 12.1

-5.5d + 11 = - 12.1

11 + 12.1 = 5.5d

23.1 = 5.5d

d = 23.1 ÷ 5.5

d = 4.2

Solve algebraically for x:<br> 3600 + 1.02x &lt; 2000 + 1.04x
Nata [24]

Answer:

x < 80000

Step-by-step explanation:

3600 + 1.02x < 2000 + 1.04x \\  \frac{ \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  - 1.04x <  \:  \:  \:  \:    \:  \:  \:  \:  \:  \:  \:  \:  \:  - 1.04x}{3600 - 0.02x < 2000}  \\  \\ 3600 - 0.02x < 2000 \\  \frac{ - 3600 \:  \:  \:  \:  \:  \:  \:  \:  \:  <  - 3600}{ - 0.02x <  - 1600}  \\  \\  \frac{ - 0.02x}{ - 0.02}   <  \frac{ - 1600}{ - 0.02}  \\  \\ x < 80000

What can you conclude about the color of the l-bow roni box? helpppppppp
Kazeer [188]

Assuming that the p-value of the color of L-Bow Roni box is below the significance level, the result would be statistically significant and vice-versa.

<h3>What is a confidence interval?</h3>

A confidence interval simply refers to a range of estimated values that defines the probability that a population parameter would fall or lie within it.

In this scenario, we can infer and logically conclude that the p-value of the color of L-Bow Roni box falls below the significance level. Consequently, the result obtained would be statistically significant.
