Answer:

D) 28.3 cm

Step-by-step explanation:

since this is a scale drawing , a proportion can be used to solve the problem. 1.4/22=1.8/x, then cross multiply and solve and you will determine that the correct answer is 28.3 cm in usatestprep

Is (-2,-3) a solution of the graphed system of inequalities?
makkiz [27]
No. A solution is any co ordinated that lies in the blank space on the graph. (-2,-3) is in the blue shades section so it is not a solution.

notsponge [240]

Complete Question

ymposium is part of a larger work referred to as Plato's Dialogues. Wishart and Leach† found that about 21.4% of five-syllable sequences in Symposium are of the type in which four are short and one is long. Suppose an antiquities store in Athens has a very old manuscript that the owner claims is part of Plato's Dialogues. A random sample of 498 five-syllable sequences from this manuscript showed that 129 were of the type four short and one long. Do the data indicate that the population proportion of this type of five-syllable sequence is higher than that found in Plato's Symposium? Use = 0.01.  

a. What is the value of the sample test statistic? (Round your answer to two decimal places.)  

b. Find the P-value of the test statistic. (Round your answer to four decimal places.)

Answer:

a) Z=2.45

b) P Value=0.0073

Step-by-step explanation:

From the question we are told that:

Probability of Wishart and Leach P=21.4=>0.214

Population Size N=498

Sample size n=12

Therefore

P'=\frac{129}{498}

P'=0.2590

Generally the Null and Alternative Hypothesis is mathematically given by

H_0:P=0.214

H_a:=P>0.214

Test Statistics

Z=\frac{P'-P}{\sqrt{\frac{P(1-P)}{n}}}

Z=\frac{0.2590-0.214}{\sqrt{\frac{0.214(1-0.214)}{498}}}

Z=2.45

Therefore P Value is given as

P Value =P(Z\geq 2.45)

P Value =1-P(Z\leq 2.45)

P Value =1-0.99268525

P Value=0.0073

Find the values of the mode when median is given to be 5 and mean is 7.
Reil [10]

Answer:

<u>Mode = 1</u>

Step-by-step explanation:

<u>Relation between the Central Measures of Tendency</u>

  • Mean, Median, and Mode are commonly referred to as the Central Measures of Tendency
  • The formula between the three is given by :
  • ⇒ <u>Mode = 3Median - 2Mean</u> or <u>Mode + 2Mean = 3Median</u>

<u></u>

<u>Solving</u>

  • We know that :
  1. Median = 5
  2. Mean = 7

Therefore,

  • Mode = 3(5) - 2(7)
  • Mode = 15 - 14
  • <u>Mode = 1</u>
