Basically all you’re doing is plugging in the inputs to the equations and see if they’re correct.
5(3)+4(-3)=3 this proves to be true
2(3)-5(-3)=21 not 19
Answer:
48,650
Step-by-step explanation:
3,475 times 14 bc thats how many days are in 2 weeks(obviously)
It would be 50
130+180= 310
360-310= 50
You get 180 from the missing side by 70 that becomes 180.
Answer:

Step-by-step explanation:
Given the mean is 3.2, standard deviation is 0.8 and the sample size is 64.
-We calculate the probability of a mean of 3.4 as follows:
#First determine the z-value:

#We then determine the corresponding probability on the z tables:

Hence, the probability of obtaining a sample mean this large or larger is 0.0228
