Rearrange the equation.
-3y=9x-18
-3y/3=9x/3-18/3 divide 3out of both sides
Y=3x-6
It is now ready to graph.
Answer:
Step-by-step explanation:
5 * 1/8= 5/8
1/7*6= 6/7
Place the whole number over 1 and multiply.
Answer:
The answer is below
Step-by-step explanation:
1)
mean (μ) = 12, SD(σ) = 2.3, sample size (n) = 65
Given that the confidence level (c) = 90% = 0.9
α = 1 - c = 0.1
α/2 = 0.05
The z score of α/2 is the same as the z score of 0.45 (0.5 - 0.05) which is equal to 1.65
The margin of error (E) is given as:

The confidence interval = μ ± E = 12 ± 0.47 = (11.53, 12.47)
2)
mean (μ) = 23, SD(σ) = 12, sample size (n) = 45
Given that the confidence level (c) = 88% = 0.88
α = 1 - c = 0.12
α/2 = 0.06
The z score of α/2 is the same as the z score of 0.44 (0.5 - 0.06) which is equal to 1.56
The margin of error (E) is given as:

The confidence interval = μ ± E = 23 ± 2.8 = (22.2, 25.8)
<em>Answer:</em>
<em>8</em>
<em>Step-by-step explanation:</em>
<em>6:0.75</em>
<em>0.75 divided by 0.75=1</em>
