Answer:
Yes
Step-by-step explanation:
We can test this claim using the one proportion z test :
x = 25 ; n = 100
Phat = x / n = 25 / 100 = 0.25
H0 : P = 0.15
H0 : P > 0.15
The test statistic :
Z = (phat - p) ÷ √p(1-p)/n
Z = (0.25-0.15) ÷ √(0.15*0.85)/100
Z = 2.8
Using the Pvalue from Zscore calculator :
α = 0.05
Pvalue (Z < 2.8) =0.0026
Pvalue < α ; We reject the Null
Answer:
9 4/5
Step-by-step explanation:
5 1/5+4 3/5
26/5+23/5
lcm of the denominator is 5
26+23 everything all over 5
49/5
9 4/5

If you start from the parent function 
, the only transformation performed is 
. In fact,
In general, a transformation like 
results in a horizontal stretch. If k>1, the function is compressed, if 0<k<1, the function is streched. If k is negative, the function is reflected around the y axis, and then you apply the logic just described.
So, in your case, k=9, which means that the graph is horizontally compressed by a factor 9.
