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 )

I rlly need help on this thank uu

Answer:

<h2>a = 2 and b = 6.</h2>

Step-by-step explanation:

The equation is given by $10x - 4 = ax + b\\(10 - a)x = 4 + b\\x = \frac{ 4 + b}{(10 - a)}$ .

The given equation is a one degree polynomial, hence it has only one solution whatever the value of a and b will be.

If the value of a is 10, then the solution of the equation will be undefined.

Hence, a is any real number rather than 10.

As for example, a = 2 and b = 6.
