alexira [117]

Answer:

90°

Step-by-step explanation:

180-124=56 so angle a is 56 and a=c so c would also be 56 next you'd have to add the right angle with angle c. 90+56=146 then to get the angle for b you would have to subtract 180-146 which is 34

34+56=90°

The proportion of students in a psychology experiment who could remember an eight-digit number correctly for t minutes was 0.9 −

kaheart [24]

Answer:

The proportion would be 0.1

Step-by-step explanation:

Given, the function that shows the proportion of students in a psychology experiment who could remember an eight-digit number correctly for t minutes,

$f(t) = 0.9 - 0.4\ln(t)$

If t = 7 minutes,

$f(7) = 0.9 - 0.4\ln(7)=0.9 - 0.77836=0.12164\approx 0.1$

Hence, the proportion that remembered the number for 7 minutes is 0.1 ( approx )
