Answer:
f(x)=1/4(4)^(x-1) -4
Step-by-step explanation:
The negative value for x=2 tells you that the vertical offset cannot be positive. That rules out the 1st and 3rd choices.
You can try x=2 in the remaining functions to see which works:
f(2) = 4(4^(2-1)) -4 = 12 ≠ -3 . . . . . . . . the 2nd choice does not work
f(2) = (1/4)(4^(2-1) -4 = -3 . . . . . . . . . . the 4th choice matches the table
Answer:
3/4 hour
Step-by-step explanation:
1/3 + 1/6 + 1/4 = 4/12 + 2/12 + 3/12 = 9/12
12*5 = 60
9*5 = 45
45/60 = 3/4
Answer:
-1 >x
Step-by-step explanation:
-4(7+6x)<-2(x-6)
-28-24x<2(x-6)
-28-24x<-2x-6
+6. +6
-22-24x<-2x
+24x +24x
-22 < 22x.
-22÷-22=1 that canceled out
+22÷-22= -1
-1>x. because we divided by a negative the inequality switched.
Hope this helped
Answer:
Im not sure what the question is but if its what the relation is between the boxes the first one would be y = x+5 the second one would be y=x-4 the third would be y= x+3 and the fourth would be y= x times 2
Step-by-step explanation:
Answer:
There is enough evidence to infer at the 10% significance level that the population mean is greater than 23
Step-by-step explanation:
Given that the sample mean is 26 and sample std dev = 9
i.e
(Right tailed test at 10% significance level)
Mean diff = 3
Test statistic t = 
Critical region is t>1.310
df 31
p value = 0.034
Since p <0.10 reject null hypothesis
There is enough evidence to infer at the 10% significance level that the population mean is greater than 23
Critical region is in the enclosed file
