Step-by-step explanation:
An exponential function is represented by function,
Where a is the y intercept and b is the growth factor.
The graph passes through (0,1) which is our y intercept so a=1
Know let find b.
The graph pass through (1,3) so plug in 1 for x and 3 for y.
So our base function is
In order for this function to shrink, we must shift the y intercept such that it is less than 1 but greater than -1.
So the only option is
Because 1/2<1
well 60/5=12
so you get $12 per yard
12*15=180
or you could notice that 5 goes into 15 3 times and then multiply 60*3 any way the answer is 180

Answer:
24 girls
Step-by-step explanation:
7 boys plus 8 girls is 15. 45 students / 15 = 3. 3 x 8 girls is 24.

you can decide if you want this answer or not :D
Step-by-step explanation:
1st , notice that our problem is about an eight part whole. I mean, the questions are around an object of 8 parts. so start thinking 1/8 ths
A) asks about P(7) ... they want to know.. how often the spinner will land on 7. so if it's totally random, 7 will happen just as likely as any of the other numbers so 7 will happen 1/8 th of the time
as a fraction it's 1/8 as a decimal it's 0.125 and as a percent it's 12.5 %
B) asks about P(2 or 6 ) [ btw, p here stands for probability ]
so it's 1/8 + 1/8 = 1/4 or one quarter of the time we would get a 2 or a 6
as a fraction it's 1/4 , as a decimal it's 0.25 and as a percent it's 25%
C) asks about P( greater than 4) or P( >4) so that's the whole left side of the circle :0
as a fraction it's 1/2 as a decimal it's 0.5 and as a percent it's 50%
D) P( not a 5) or P( ~=5) so every thing but a 5
as a fraction that's 7/8 as a decimal it's 0.875 and as a percent that 87.5 %
I'll take the odds on that last one to win the lottery plz :)
