Trying using photo math or on google there is actually a slope calculator called functions calculator in stupid sorry for not answering it lol
Answer:
66
Step-by-step explanation:
The bases are both the same so it's 3*3 for both of them.
The sides are also the same so it's 3*4 for all four of them.
3*3+3*3+3*4+3*4+3*4+3*4
9+9+12+12+12+12
18+48
66
Answer:
63 + 10
Step-by-step explanation:
when you do parenthesis and the number is next to another one with no symbol you multiply so 4-2 = 2 2 x 5 = 10 giving you 63 + 10
Answer:
we can conclude that there is no significant evidence to conclude that the mean score in 2010 differs from the mean score in 2009.
Step-by-step explanation:
H0 : μ = 582
H1 : μ < 582
Test statistic :
T = (xbar - μ) ÷ σ/√n
Xbar = 515 ; n = 20 ; σ = 120
T = (515 - 582) ÷ 120/√20
T = -67 / 26.832815
T = 2.50
Pvalue at t score = 2.50 ; df = 19 is 0.0187
At α = 0.0187
Pvalue > α ; Hence, we fail to reject the Null
Hence, we can conclude that there is no significant evidence to conclude that the mean score in 2010 differs from the mean score in 2009.
