Look at the picture of a scaffold used to support construction workers. The height of the scaffold can be changed by adjusting t
timama [110]

Step-by-step explanation:

<u>Using Pythagorus theorem</u> :

(A)

PR =  \sqrt{ {PQ}^{2}  +  {QR}^{2} }

PR =   \sqrt{196 + 81}  =  \sqrt{277}  = 16.64 \: cm

(B)

QR  =   \sqrt{ {PQ}^{2}  +  {PR}^{2} }  =  \sqrt{196 +324 }  = 22.8 \: cm

Suppose the number of insect fragments in a chocolate bar follows a Poisson process with the expected number of fragments in a 2
leonid [27]

Answer:

a)The expected number of insect fragments in 1/4 of a 200-gram chocolate bar is 2.55

b)0.6004

c)19.607

Step-by-step explanation:

Let X denotes the number of fragments in 200 gm chocolate bar with expected number of fragments 10.2

X ~ Poisson(A) where \lambda = \frac{10.2}{200} = 0.051

a)We are supposed to find the expected number of insect fragments in 1/4 of a 200-gram chocolate bar

\frac{1}{4} \times 200 = 50

50 grams of bar contains expected fragments = \lambda x = 0.051 \times 50=2.55

So, the expected number of insect fragments in 1/4 of a 200-gram chocolate bar is 2.55

b) Now we are supposed to find the probability that you have to eat more than 10 grams of chocolate bar before ending your first fragment

Let X denotes the number of grams to be eaten before another fragment is detected.

P(X>10)= e^{-\lambda \times x}= e^{-0.051 \times 10}= e^{-0.51}=0.6004

c)The expected number of grams to be eaten before encountering the first fragments :

E(X)=\frac{1}{\lambda}=\frac{1}{0.051}=19.607 grams

miskamm [114]
The formula q \Rightarrow p means that from statement q implies statement p. 

When statements p="two linear functions have different coefficients of x" and q="the graphs of two functions intersect at exactly one point", then the statement q \Rightarrow p have a form: "If the graphs of two functions intersect at exactly one point, then two linear functions have different coefficients of x."

The answer is C. Why? Well, see below!

A would be incorrect because the problem is asking what the area of the stamp would be. In order to find area, we multiply length and width by each other. The given equation we initially had shows division, and would therefore be incorrect. B would be incorrect because although the equation has the correct evaluation symbol, the formula for identifying length would be L = A / W, which means length equals area divided by width. Because the area is 1/4 in this problem, the expression used for evaluation would be 1/4 divided by 1/5. D is incorrect because, like B, the evaluation expression would be 1/4 divided by 1/5.

Your final answer: Because C is the only problem that gives us a corresponding expression to the initial expression, C is the correct answer. If you need extra help, let me know and I will gladly assist you.
