Answer:
-3 and -16
Step-by-step explanation:
Difference: -3-(-16)= 13
-3(-16)= 48
Answer:
Step-by-step explanation:
H0 : μ = 46300
H1 : μ > 46300
α = 0.05
df = n - 1 = 45 - 1 = 44
Critical value for a one tailed t-test(since population standard deviation is not given).
Tcritical = 1.30
The test statistic :(xbar - μ) ÷ (s/sqrt(n))
The test statistic, t= (47800-46300) ÷ (5600√45)
t = 1500
t = 1500 / 834.79871
t = 1.797
The decision region :
Reject H0: if t value > critical value
1. 797 > 1.30
Tvalue > critical value ; We reject H0
Hence, there is sufficient evidence to conclude that cost has increased.
6% tax=
6/100 x $19.08
=$1.1448
Total price- 6% tax
$19.08 - $1.1448
= $17.9352
Cost of the cat food- x
x= $17.9352 - $12.25
x = $5.6852
Group and factor out the linear coefient
(3x^2+4x)+?=1+????
3(x^2+4/3x)+?=1+????
4/3 divided by 2 is 2/3
2/3 squared is 4/9
add negative and negative inside
3(x^2+4/3x+4/9-4/9)+?=1+????
factor perfect square
3((x+2/3)^2-4/9)+?=1+????
distribute
3(x+2/3)^2-4/3+?=1+????
add 4/3 to both sides
3(x+2/3)^2+?=7/3+????
minus? from both sides
3(x+2/3)^2=7/3+????-?
dunno what missing number is, maybe
hmm
4/9 times 3=4/3
the missing number is 4/3
No because a perfect square would be 1 whole number times itself. and no number times itself equals 27
