Arandom sample of pickles in a jar has the following weights in grams: 68, 54, 59, 70, 69, 65, 73, 59, 74, and 54 what is the nest prediction for the mean weight of all pickles in the jar? 64.5g 54g 66.5g 59g

64.5g

Step-by-step explanation:

In order to solve this you just have to add all of the mass of the pickles and then you just have to divide by the number jars:

68+54+59+70+69+65+73+59+74+54=645 grams

So then you just divide this by 10:

645/10=64,5 grams as amean weight.

So the answer would be 64.5 grams as a mean weight.

m∠a is 90°

m∠b is 40°

answer:   35 % is the probability of a late departure or an early arrival.

step-by-step explanation:

let l represents the late departure and e represents the early departure.

then, according to the question,

p(l) = 12 %,   p(e) = 27 % and = 4 %

and, we have to find out,

but, we know that,

which is the required equation that will use to find the probability of a late departure or an early departure.

therefore,   the probability of a late departure or an early arrival =   35 %
