For the reaction shown, compute the theoretical yield of the product in grams for each of the following initial amounts of reactants.
Ti(s)+2F2(g)→TiF4(s)

1.0 gTi; 1.0 gF2 Express your answer using two significant figures.

4.8 gTi; 3.2 gF2 Express your answer using two significant figures.

0.388 gTi; 0.341 gF2 Express your answer using three significant figures.

Two 2.1-mm-diameter beads, C and D, are 10 mm apart, measured between their centers. Bead C has mass 1.0 g and charge 1.6 nC. Bead D has mass 2.3 g and charge -1.0 nC.

1) If the beads are released from rest, what is the speed v_C of C at the instant the beads collide?

2) What is the speed v_D of D at the instant the beads collide?

QUESTION PART A: Many investors and financial analysts believe the Dow Jones Industrial Average (DJIA) gives a good barometer of the overall stock market. On January 31, 2006, 9 of the 30 stocks making up the DJIA increased in price (The Wall Street Journal, February 1, 2006). On the basis of this fact, a financial analyst claims we can assume that 30% of the stocks traded on the New York Stock Exchange (NYSE) went up the same day.

A sample of 61 stocks traded on the NYSE that day showed that 6 went up.

You are conducting a study to see if the proportion of stocks that went up is is significantly less than 0.3. You use a significance level of α=0.01α=0.01.

What is the test statistic for this sample? (Report answer accurate to three decimal places.)
test statistic =

What is the p-value for this sample? (Report answer accurate to four decimal places.)
p-value =

The p-value is...

• less than (or equal to) αα
• greater than αα

This test statistic leads to a decision to...

• reject the null
• accept the null
• fail to reject the null

As such, the final conclusion is that...

• There is sufficient evidence to warrant rejection of the claim that the proportion of stocks that went up is is less than 0.3.
• There is not sufficient evidence to warrant rejection of the claim that the proportion of stocks that went up is is less than 0.3.
• The sample data support the claim that the proportion of stocks that went up is is less than 0.3.
• There is not sufficient sample evidence to support the claim that the proportion of stocks that went up is is less than 0.3.

QUESTION PART B: You want to obtain a sample to estimate a population proportion. At this point in time, you have no reasonable estimate for the population proportion. You would like to be 99.9% confident that you esimate is within 2.5% of the true population proportion. How large of a sample size is required?

n =



Do not round mid-calculation. However, use a critical value accurate to three decimal places.

(I have posted this three different times and it has been wrong, so please!! it will help me a lot)

1. Watch the TED Talk by Bashar Wali, president of Provenance Hotel Group. Do you agree or disagree with what he discussed in his talk? Share your overall impressions and thoughts about what he had to share. Your response should be at least one full paragraph.

According to a research​ institution, the average hotel price in a certain year was ​$99.07. Assume the population standard deviation is ​$20.00 and that a random sample of 31 hotels was selected. Complete part d below.

d. What is the probability that the sample mean will be between ​$97 and ​$99​? _______​(Round to four decimal places as​ needed.)

Question D2

A wedding banquet is going to be held next week in a hotel. To have better preparation for this wedding banquet, the event department will hold a meeting tomorrow. Identify who should join this meeting. Regarding to EACH identified participant, illustrate ONE information from the banquet event order that they concern.
