Answer:
256m^2
Step-by-step explanation:
you can cut up the figure.
A1=bh
A1= 24x8
A1=192m^2
A2=bh
A2= bh
A2=8x8
A2=64m^2
A1+A2= Atotal
A=192+64
A=256m^2
Answer:
40x?

Answer:
Roland is right, he can be 95% sure that average gas prices have gone up since the same time last year.
Step-by-step explanation:
Let μ be average gas price around Syracuse.
Then hypotheses are:
μ = $2.68
μ > $2.68
Then test statistic can be calculated as:
z=
where
- X is the Roland's calculated average gas prices of 50 gas stations ($2.74)
- M is the average average gas prices in the entire of Syracuse last year
- s is the standard deviation ($0.11)
Then z=
≈ 3.86
Since P-value of test statistic ≈ 0.00006 <0.05 (significance level), we can reject the null hypothesis.
Answer:
The answer to your question is -3 and 2
Step-by-step explanation:
If an equation is factored, to find the roots, just equal each term to zero.
(x + 3)(x - 2) = 0
Equal each term to zero
x₁ + 3 = 0 x₂ - 2 = 0
Solve for x
x₁ = -3 x₂ = 2
The solutions to this quadratic equation are -3 and 2.
Convert all of the into decimal.
0.4
60 ÷ 100 = 0.6
0.2
0.4 = 0.4
60% = 0.6

= 0.2
in order from least to greatest:
0.2, 0.4, 0.6
, 0.4, 60% is your answer =)
