Three quadrilaterals exist such that GHJK ≅ ASDF and GHJK ≅ VBNM.
erik [133]

Among the congruent quadrilaterals, the segment that must also measure 3 cm is: A. A F.

<h3>What are Congruent Quadrilaterals?</h3>

Congruent quadrilaterals have corresponding congruent angles and sides.

Given that, GHJK ≅ ASDF and GHJK ≅ VBNM, it means that all corresponding sides and angles are equal to each other.

MV corresponds to KG and A F. If MV = 3 cm, then one segment that must measure 3 cm is:

A. A F

Ramona and Beezus love to read books. Ramona reads 16 less than 5 times the number of books Beezus reads. Ramona reads 134 books
Fittoniya [83]
I think the answer is 30, because if 134 +16 is 5 times the number of books Beezus reads, than just divide by 4 for the answer of 30

Anas wants to build a one-sample z interval with 85% confidence to estimate what proportion of users will click an advertisement
klasskru [66]

Answer:

See below

Step-by-step explanation:

<u>Check One Sample Z-Interval Conditions</u>

Simple Random Sample? √

np≥10? √

n(1-p)≥10? √

<u>One-Sample Z-Interval Information</u>

  • Formula --> CI=\hat{p}\pm z^*\biggr(\sqrt{\frac{\hat{p}(1-\hat{p})}{n}}\biggr)
  • Sample Proportion --> \hat{p}=\frac{54}{250}=0.216
  • Critical Value --> z^*=1.4395 (for a 85% confidence level)
  • Sample Size --> n=250
  • Margin of Error (MOE) --> \sqrt{\frac{\hat{p}(1-\hat{p})}{n}}

<u>Problem 1</u>

As stated previously, Anas should use the critical value z^*=1.4395 to construct the 85% confidence interval

<u>Problem 2</u>

Given our formula for the margin of error (MOE), the value is MOE=\sqrt{\frac{\hat{p}(1-\hat{p})}{n}}=\sqrt{\frac{0.216(1-0.216)}{250}}\approx0.026

<u>Problem 3</u>

The 85% confidence interval would be CI=\hat{p}\pm z^*\biggr(\sqrt{\frac{\hat{p}(1-\hat{p})}{n}}\biggr)=CI=0.216\pm 1.4395(0.026)\appro=\{0.1786,0.2534\}, which means that we are 85% confident that the true proportion of people that clicked on the advertisement is between 0.1786 (~45 people) and 0.2534 (~63 people)

<u>Problem 4</u>

Increasing the sample size to n=500 is going to decrease the margin of error because it is a closer representation of the population, but, alas, requires more time, energy, and resources to observe.
