Answer:

8.4

Step-by-step explanation:

Since the four horizontal lines are parallel, they each form congruent corresponding angles with the transversal line SP.  Since PQ = QR = RS, that means the vertical distances between the parallel lines is equal.

Since the parallel lines are equally spaced, and form congruent angles with the transversal line TU, then TX = XZ = ZU = 2.8.

So the length of TU is 2.8 + 2.8 + 2.8 = 8.4.

Janice is building a fence around a portion of her rectangular yard. The length of yard she will enclose is x, and the width is
Kipish [7]

We are given

length of rectangular yard is x

so, L=x

width of rectangular yard is

so, W=2x^2-98x+5

We are given

the length of the enclosed yard is 50 feet

so, we get

L=x=50

now, we can plug x=50 and then we can find width

W=2(50)^2-98(50)+5

W=105

now, we can find total fencing length

so, total fencing length is

=2L+2W

now, we can plug values

=2\times 50+2\times 105

=310feet

now, we are given

the cost of fencing is $13 per foot

so,

total cost = (cost of fencing)*(total fencing length)

we can plug values

C=13\times 310

C=4030

So, Janice will spend $4030.........Answer

Customers arrive at a restaurant according to a Poisson distribution at a rate of 20 customers per hour. The restaurant opens fo
jenyasd209 [6]

Answer:

0.087

Step-by-step explanation:

Given that there were 17 customers at 11:07, probability of having 20 customers in the restaurant at 11:12 am could be computed as:

= Probability of having 3 customers in that 5 minute period. For every minute period, the number of customers coming can be modeled as:

X₅ ~ Poisson (20 (5/60))

X₅ ~ Poisson (1.6667)

Formula for computing probabilities for Poisson is as follows:

P (X=ₓ) = ((<em>e</em>^(-λ)) λˣ)/ₓ!

P(X₅= 3) = ((<em>e</em>^(-λ)) λˣ)/ₓ! =  (e^-1.6667)((1.6667²)/3!)

P(X₅= 3) = (2.718^(-1.6667))((2.78)/6)

P(X₅= 3) = (2.718^(-1.6667))0.46

P(X₅= 3) = 0.1889×0.46

P(X₅= 3) = 0.086894

P(X₅= 3) = 0.087

Therefore, the probability of having 20 customers in the restaurant at 11:12 am given that there were 17 customers at 11:07 am is 0.087.

Jeremy buys 2 sweaters for $18 each. He can use only one of the following coupons:
katen-ka-za [31]

Jeremy should use coupon 2 because when you multiply both the sweaters (36) by .25 you get 9, and then you subtract 36 by 9 which is 27.

But when you use coupon 1 you multiply 18 by .40 which is 7.20 where you subtract 18 by 7.20 which is 10.80. You then add 10.80 with 18 which is 28.80.

I don't even know what the question is but I found the same problem and this was the answer
