Given the equation 4(3b + 2)² = 64,
dividing both sides of the equation by 4, we have
(3b + 2)² = 16 and getting the square root of both sides,
(3b + 2) = 4 and (3b + 2) = -4
We can solve for b for each equation and have
3b = 2 | 3b = -6
b = 2/3 | b = -2
Therefore, the values of b are 2/3 and -2 and from the choices, the answer is <span>A: b = 2/3 and b = -2.</span>
Answer:
0.75 = 75% probability that he will have to wait at a red light for more than 15 seconds
Step-by-step explanation:
At each second, the stoplight is equally likely to change, which means that we use the uniform probability distribution to solve this question.
Uniform probability distribution:
Has two bounds, a and b. The probability of finding a value higher than x is given by:
Red for 60 seconds
So when Jamal arrives it can change in any number of seconds between 0 and 60, that is, 
Probability that he will have to wait at a red light for more than 15 seconds?
0.75 = 75% probability that he will have to wait at a red light for more than 15 seconds
Answer:
b=-3

Answer:
the best predicted pulse rate of a woman who is 66 in tall = 79.78 beats per minute
Step-by-step explanation:
We are given that;
Regression line: y^ = 18.4 + 0.93x
Now we want to find out the best predicted pulse rate of a woman who is 66 in tall.
Thus;
If x = 66, then the predicted height is:y^ = 18.4 + 0.93(66)
y^ = 79.78 beats per minute
