GARY DREW A RECTANGLE WITH A PERIMETER OF 20 INCHES. WHAT COULD BE THE LENGTH,WIDTH,AND AREA FOR THE RECTANGLE THAT GARY DREW?

Ilia_Sergeevich [38]

Assume L=1.5W, where W=width, L= Length of the triangle.

Therefore,

Perimeter (P) = 2(W+L) = 2(W+1.5W) = 2(2.5W) = 5W=20 => W=20/5 = 4 in

Then, L=1.5W = 1.5*4 = 6 in

Area, A= L*W = 6*4 = 24 in^2

Suppose it is known from large amounts of historical data that X, the number of cars that arrive at a specific intersection duri

Andrew [12]

Answer:

a) P(x>8) = 0.3937

b) P(x = 2) =0.04661

Step-by-step explanation:

a) From to find the probabilty that in this specific time period, more than 8 cars arrive at the intesection, we use the probability function thus

P(x>8) = 1 - P(x≤8), Cause you can use the complement for calculate this probability , then:

P(x≤8) = $\frac{e^{-6}*6^{0} }{0!}+\frac{e^{-6}*6^{1} }{1!}+\frac{e^{-6}*6^{2} }{2!}+...$ , until x= 8, then you obtain:

P(x≤8)=0.6063 and

P(x>8) = 1 - P(x≤8)= 1-0.6063 = 0.3937

b) P(x=2)= $\frac{e^{-6}*6^{2} }{2!}$

P(x = 2) =0.04661

A phone can update 6 apps every 4 minutes. At this rate, how many apps can the phone update in 10 minutes? Show your work.

Arada [10]

Answer:

15 apps.

Step-by-step explanation:

Divide 6 by 4, and you get how much apps that phone can do in a single minute. Then multiply that number by 10 and you get 15 apps in 10 minutes.
