The heights in inches, of some small trees for sale at a garden store are 62, 62, 59, 61, 59, 70, 59, and 62. What is the median
Nana76 [90]

Answer:

Step-by-step explanation:

the mean height, remember is the average

62+62+59+61+59+70+59+62=494/8=61.75

median is the middle value, so we will write the numbers in order

59,59,59,61,62,62,62,70

we have an even number so we add the middle numbers and divide by 2,

the median=61+62=123/2=61.50  

mode is the number that occurs most often : 62 and 59

Please help:<br> In Δ ABC, sin A=88, sin B=42, and a =17, find the length of b.
iren2701 [21]

Answer:

Step-by-step explanation:

Use the law of sines.

\frac{sin A}{a} = \frac{sin B}{b} \\

Plug values in.

\frac{sin88}{17} = \frac{sin42}{b}\\

Cross multiply.

bsin88 = 17sin42\\b = 11.38

Hope that helps.

I can't figure this one out please help!
Helen [10]

Answer:


Step-by-step explanation:

The first answer is that the sale price is 25% cheaper its a dumb question.

The second answer is the 2nd option because it states that sale prices are 30% of the original. For example if you had a $100 item it would cost you 30% of that original price. But if you went to the first store it would cost you $70 dollars because its 30% off of the original price.

Given that x has a Poisson distribution with
Alex
The Poisson probability distribution function is
P(x;\mu)= \frac{e^{-\mu}\mu ^{x}}{x!}
where
μ = mean number of successes
x =  actual or expected number of successes

Given:
μ = 13
x = 5

Therefore the probability that x=5 is
P(x = 5) = (e⁻¹³*13⁵)/5!
             = 0.8392/120
             = 0.006994
             = 0.0070  (to 4 dec. places)

Answer: 0.0070  (to 4 decimal places)

It is interesting to observe P(x) as x varies, as in the graph shown below.
