Identify the parameters in the following situation. When Jackie is camping, she sees 6 shooting stars every hour, on average. Wh

andrey2020 [161]

Answer:

The probability that she sees exactly 4 shooting stars in the next hour is 0.13

Step-by-step explanation:

An assumption is made that she see the shooting stars of 6 every hour based on a poisson distribution.

$P(X = x) = \frac{e^{-m} m^{x} }{x!}$

where m is the average per hour = 6

$P(X = x) = \frac{e^{-m} m^{x} }{x!}\\P(X = 4) = \frac{e^{-6} 6^{4} }{4!}\\P(X = 4) = \frac{0.002478752 * 1296 }{4!}\\P(X = 4) = \frac{3.212462592}{24}\\P(X = 4) = 0.133852618\\P(X = 4) = 0.13$

Distance Formula: $d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Step-by-step explanation:

Step 1: Define

Point C (-2, 6)

Point D (10, -8)

Step 2: Find distance d

Substitute: $d = \sqrt{(10+2)^2+(-8-6)^2}$
Add/Subtract: $d = \sqrt{(12)^2+(-14)^2}$
Exponents: $d = \sqrt{144+196}$
Add: $d = \sqrt{340}$
Simplify: $d =2 \sqrt{85}$
Evaluate: $d = 18.4391$
Round: $d \approx 18.4$

Find value of x also the answer choices are a. 62.5 b. 9.65 c. 71.35 d. 103.25

weeeeeb [17]

Answer:

D.103.25

Step-by-step explanation:

To find the value of x, you need to know that the height of the donkey and the cactus are proportional and that the shadow of the donkey and cactus are also proportional to each other. Thus, you need to create a proportional and cross multiply to find the value of x.

x/59 = 7/4

After you cross multiply, the equation should look like this:

4x=413

Finally, you divide both sides or numbers by 4 to get 103.25 as your answer! Hope this helps!
