28%. Boom. :) this is the chance of getting one red heart
Hi there! I can help you! Okay. The numbers are separate from each other. One is negative and the other is positive. To solve this problem, let’s find the absolute value of both numbers and add them up. The absolute value is a number’s distance from 0 and the answer is always positive. The absolute value of -7 is 7. The absolute value of 3 is 3. 7 + 3 = 10. The distance between -7 and 3 is 10. The answer is D: 10.
The answer is A one triangle all those angles equal 180
<span>the probability that the average mileage of the fleet us between 27.2 and 28.8 will be:
27.2<x<28.8
this will be:
P(x<28.8)-P(x<27.2)
To evaluate this we use the z-score formula:
P(x<28.2)=P(z<Z)
Z=(x-</span>μ)/σ
μ-mean
σ-standard deviation
thus
z=(28.2-28)/5=0.04
thus
P(x<28.2)=0.5160
p(x<27.2
z=(27.2-8)/5=-0.16
P(z<-0.16)=0.4364
thus
P(x<28.8)-P(x<27.2)=0.5160-0.4364=0.0796
Answer: 0.0796
