In random samples, 74 of 250 persons who watched a certain television program on a small tv set and 92 of 250 persons who watched the same program on a large set remembered 2 hours later what products were advertised. use the χ2 statistic to test the null hypothesis θ1 = θ2 against the alternative hypothesis θ1 z θ2 at the 0.01 level of significance.

the answer is a

step-by-step explanation:

because if you put 1 in to the square root of x it equals 300.

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)

answer: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.
