give me brainiest wink wink
Set up a system of equations. If w is the number of women and m is the number of men, we know that w+m=55, and that w=m-3. If you solve this, you get that m-3+m=55 → m=29.
The authors of a certain paper describe a study to evaluate the effect of mobile phone use by taxi drivers in Greece. Fifty taxi drivers drove in a driving simulator where they were following a lead car. The drivers were asked to carry on a conversation on a mobile phone while driving, and the following distance (the distance between the taxi and the lead car) was recorded. The sample mean following distance was 3.70 meters and the sample standard deviation was 1.17 meters.
a. Construct and interpret a 95% confidence interval for m, the population mean following distance while talking on a mobile phone for the population of taxi drivers.
b. What assumption must be made to generalize this confidence interval to the population of all taxi drivers in Greece?
Answers
a. The population of taxi drivers in Greece falls between 3.3766 meters and 4.0234 meters.
b. The assumption is that the sample of 50 taxi drivers is representative of the population.
a.
To construct a 95% confidence interval for the population mean following distance while talking on a mobile phone, we can use the formula:
Confidence Interval = sample mean ± (critical value × standard error)
The standard error:
Standard Error = sample standard deviation / √(sample size)
Standard Error = 1.17 / √(50)
Standard Error = 0.165
Since the sample size is large (n > 30), we can use the Z-table to find the critical value.
For a 95% confidence level, the critical value is approximately 1.96.
Now we can construct the confidence interval:
Confidence Interval = 3.70 ± (1.96 × 0.165)
Confidence Interval = 3.70 ± 0.3234
Confidence Interval = (3.3766, 4.0234)
Interpretation: We are 95% confident that the true population means following distance while talking on a mobile phone for the population of taxi drivers in Greece falls between 3.3766 meters and 4.0234 meters.
b.
The assumption that must be made to generalize this confidence interval to the population of all taxi drivers in Greece is that the sample of 50 taxi drivers is representative of the population. It is assumed that the sample was randomly selected and that the taxi drivers included in the study are a fair and unbiased representation of all taxi drivers in Greece.

One bar of candy A and two bars of candy B have 777 calories. Two bars of candy A and one bar of candy B contain 783 calories. Find the caloric content of each candy bar.
Answers
Answer:
A has 263 calories
B has 257 calories
Step-by-step explanation:
system of equations:
a + 2b = 777
2a + b = 783
I multiplied the first equation by -2 to eliminate the 'a' terms
-2a - 4b = -1554
+ 2a + b = 783
-3b = -771
b = 257
solve for 'a'
a + 2(257) = 777
a + 514 = 777
a = 263

Jenny is planning an extended trip to Russia.The table below shows a list of cities which she would like to visit during her stay, along with the amount of money she anticipates needing to spend on travel, lodging, and similar expenses in each city. All costs are given in Russian rubles (RUB).

Cost (RUB)
Izhevsk
4,721
Novosibirsk
4,870
Nizhny Novgorod
6,920
Moscow
5,485
Chelyabinsk
5,217
Saint Petersburg
5,960
Tolyatti
5,598
Yaroslavl
4,901
Even though Jenny wants to go to each of these cities, her budget is only RUB 33,000, so she recognizes that she must change her itinerary and choose not to visit some cities. Which of the following pairs of cities will not put Jenny back under budget if she drops them?
a.
Moscow and Chelyabinsk
b.

c.

THE ANSWER IS D. YAROSLAVI AND TOLYATTI
EXPLANATION: the total of all cities is 43,672. If we subtract 4901 for Yaroslavi and 5598 for Tolyatti we have 33,173 (43,672 - 4901 - 5598 = 33,173). This would still be over Jenny's budget
