x=25-14=11
Tiffany and Adele sold 11 cookies and 14 brownies
Answer:
x=-1
Step-by-step explanation:
-3x=-10+13 - -3x=3 - -3 = -1
What you need to do is plug each x value into the equation to find out the corresponding y value.
for example, when x=-2, y=(-2)²+3(-2)+2=4-6+2=0
the outputs are 0, 0, 2, 6, 12
Answer:
58.3% to the nearest tenth.
Step-by-step explanation:
The prime numbers from 1 to 6 are 2,3 and 5.
The probability of a prime number taken from the result of the 300 throws:
= (sum of the frequencies for 2, 3 and 5) / ( total throws)
= (60 + 55 + 60) / 300
= 0.5833 or 58.3%.
