Quan bought 8.6 meters of frabic. how many cm of fabric did he buy

stira [4]

When you convert from meters to centimeters, you always multiply by 100, which means that 1 meter = 1 * 100 cm = 100 cm
So, 8.6 meters = 8.6 * 100 cm = 860 cm

Hope this Helps :)

On Texas Avenue between University Drive and George Bush Drive, accidents occur according to a Poisson process at a rate of thre

Zarrin [17]

Answer:

(a) The probability is 0.6514

(b) The probability is 0.7769

Step-by-step explanation:

If the number of accidents occur according to a poisson process, the probability that x accidents occurs on a given day is:

$P(x)=\frac{e^{-at}*(at)^{x} }{x!}$

Where a is the mean number of accidents per day and t is the number of days.

So, for part (a), a is equal to 3/7 and t is equal to 1 day, because there is a rate of 3 accidents every 7 days.

Then, the probability that a given day has no accidents is calculated as:

$P(x)=\frac{e^{-3/7}*(3/7)^{x}}{x!}$

$P(0)=\frac{e^{-3/7}*(3/7)^{0}}{0!}=0.6514$

On the other hand the probability that February has at least one accident with a personal injury is calculated as:

P(x≥1)=1 - P(0)

Where P(0) is calculated as:

$P(x)=\frac{e^{-at}*(at)^{x} }{x!}$

Where a is equivalent to (3/7)(1/8) because that is the mean number of accidents with personal injury per day, and t is equal to 28 because 4 weeks has 28 days, so:

$P(x)=\frac{e^{-(3/7)(1/8)(28)}*((3/7)(1/8)(28))^{x}}{x!}$

$P(0)=\frac{e^{-(3/7)(1/8)(28)}*((3/7)(1/8)(28))^{0}}{0!}=0.2231$

Finally, P(x≥1) is:

P(x≥1) = 1 - 0.2231 = 0.7769

IT IS DUE AT 11:59PM. PLEASE HELP!!!!

Hello from MrBillDoesMath!

Answer: b = 4, h = 13

Discussion:

For a triangle with base b" and height "h, the area formula is

A= (1/2)bh.

In our case A = 26, h = 5b-7, so

26 = (1/2) b (5b-7). Multiply both sides by 2:

26*2 = b(5b-7) =>

52 = b(5b-7) =>

52 = 5b^2 - 7b => (subtract 52 from both sides)

5b^2 - 7b - 52 = 0. This factors as follows:

(b - 4) (5 b + 13) = 0 (use quadratic formula to find this)

so b = 4 and h = 5b -7 = 5*4 - 7 = 13

Thank you,

MrB
