Answer:
Step-by-step explanation:
A vertical stretch of a function means the output values have changed by a factor of 3 or multiplication by 3. Recall, an exponential function has the basic form
.
If our equation is , then a=1. To stretch it vertically by a factor of 3, we multiply a by 3. So 1(3)=3. The value of a now becomes 3.
The probability of Jamie picking a blue marble is greater. The ratio of this probability would be 7:3
The answer is (3). 5\12 1\4 = 37.5\150
1.5m= 150cm
37.5 + 50 = 87.5
87.5 x 12 = 750 750 \ 150 = 5
answer = 5\12
