Answer:
Answer is the chart 4.
Step-by-step explanation:
f(x) = -2x + 6
when x = 0, f(0) = 6
when x = 2, f(2) = -2(2) + 6 = 2
and so on....
Only the chart number 4 matched the above
Answer is 4
Translating this word problem into an algebraic equation, we get:
3x - 2/5 = 8/5.
Let's combine the constants: adding 2/5 to both sides of this equation yields
3x = 10/5, or 3x = 2.
Solving for x: x = 2/3
Answer: 82.88
Step-by-step explanation:
BxHxW
7.4 x 3.2 = xxx
7.4 x 8 = xxx
So, what you'll do is combine both of the sums, and you will get 82.88
Answer:
Margin of error = 0.09
Confidence interval = (0.29, 0.41)
Step-by-step explanation:
Sample size, n = 1023
p = 38%
= 0.38
Standard deviation, σ = 1.5
Consider the level of confidence to be 95%
So, corresponding z* value for 95% confidence level = 1.96
![\text{Now, Margin of error = }z^*\times \frac{\sigma}{\sqrt{n}}\\\\\text{Margin of error = }1.96\times \frac{1.5}{\sqrt{1023}}\\\\\textbf{Margin of error = }\bf 0.09](https://tex.z-dn.net/?f=%5Ctext%7BNow%2C%20Margin%20of%20error%20%3D%20%7Dz%5E%2A%5Ctimes%20%5Cfrac%7B%5Csigma%7D%7B%5Csqrt%7Bn%7D%7D%5C%5C%5C%5C%5Ctext%7BMargin%20of%20error%20%3D%20%7D1.96%5Ctimes%20%5Cfrac%7B1.5%7D%7B%5Csqrt%7B1023%7D%7D%5C%5C%5C%5C%5Ctextbf%7BMargin%20of%20error%20%3D%20%7D%5Cbf%200.09)
Hence, confidence interval = p ± margin of error
= 0.38 ± 0.09
= (0.29, 0.47)
