Answer:
3x + x + 100° = 180°
⇔ 4x = 80°
⇔ x = 20°
Step-by-step explanation:
Hello betzy166817!
The correct answer is: <u>250 miles per inch.</u>
You can multiply the number of inches on the map by 250 to find the number of miles.

Im pretty sure it’s 12 miles, hope this helped :)
Answer:
Take whatever information you want from this but I don't think you'll need everything I'm gonna say.
Step-by-step explanation:
Both graphs have the same shape and open in the same direction. The only difference is that g(x) is translated down 2 units.
(I don't think you need this but) One more difference is that g(x) will have two x intercepts while x^2 will only have one point touching the x axis.
Answer:
p-value: 0.0367
Decision: Reject H₀
Step-by-step explanation:
Hello!
Hypothesis to test:
H₀:ρ₁-ρ₂=0
H₁:ρ₁-ρ₂>0
The statistic to use to test the difference between two population proportions is the approximation of Z
Z=<u> (^ρ₁-^ρ₂)-(ρ₁-ρ₂) </u> ≈N(0;1)
√ (<u>^ρ₁(1-^ρ₁))/n₁)+(^ρ₂(1-^ρ₂)/n₂))</u>
Z=<u> (0.28-0.15)-0 </u>= 1.79
√ (<u>0.28(1-0.28)/200)+(0.15(1-0.15)/300)</u>
p-value
Remember: The p-value is defined as the probability corresponding to the calculated statistic if possible under the null hypothesis (i.e. the probability of obtaining a value as extreme as the value of the statistic under the null hypothesis).
P(Z>1.79)= 0.0367
Conclusion:
Comparing the p-value against the significance level, you can decide to reject the null hypothesis.
I hope you have a SUPER day!
