Set it up as 15x-13+8x+29+2y=180 and then just find a algebra calculator and put that formula in there
Answer: Earth’s Best $1.67 Kroger $2
Step-by-step explanation:
$0.80 multiplied by 3 is $2.40 and $1.33 multiplied by 2 is $2.66.
$1.25 multiplied by 3 is $3.75 and $0.75 multiplied by 2 would be $1.50.
$0.80 multiplied by 3 is $2.40 and $0.75 multiplied by 2 is $1.50.
$1.67 multiplied by 3 is $5.01, but if you round it to the nearest cent, it’s $5 and $2 multiplied by 2 is $4, of course.
Hope this helps!
Answer:
the correct answer would be C
Step-by-step explanation:
Answer: the t-test statistic is - 1.77
Step-by-step explanation:
For the null hypothesis,
H 0: μ = 2600
For the alternative hypothesis,
H a: μ ≠ 2600
This is a two tailed test
Since no population standard deviation is given, the distribution is a student's t.
Since n = 50,
Degrees of freedom, df = n - 1 = 50 - 1 = 49
t = (x - µ)/(s/√n)
Where
x = sample mean = $2450
µ = population mean = $2600
s = samples standard deviation = $600
Therefore,
t = (2450 - 2600)/(600/√50) = - 1.77
