Round 259.98991 to the nearest hundredths
Answer:
259.99
Step-by-step explanation:
You look at the hundreths place and see if the number behind it is bigger than 5, and if it is then you up it by one, and if it's 4 and below then you round it to zero. In this case you up it by one and you get 269.99.

Construct the indicated confidence interval for the difference between population proportions p1 - p2. Assume that the samples are independent and that they have been randomly selected. A marketing survey involves product recognition in New York and California. Of 558 New Yorkers surveyed, 193 knew the product while 196 out of 614 Californians knew the product. Construct a 99% confidence interval for the difference between the two population proportions.
Answer:
-0.0423≤p≤0.0977
Step-by-step explanation:
The margin error formula is expressed as;
ME = p±√p(1-p)/n
n is the sample size
For the first population proportion p1:
p1 = 193/558 = 0.3469
n1 = 558
p2 = 196/614 = 0.3192
n2 = 614
Taking the difference in the confidence of the proportion
p = p1-p2
p = 0.3469-0.3192
p= 0.0277
Get the margin of error
Margin of error = z*√p(1-p)/n
Margin of error = 2.5758*√0.35(1-0.35)/558 + 2.5758*√0.32(1-0.32)/614
Margin of error = 2.5758*√0.35(0.65)/558 + 2.5758*√0.32(0.68)/614
Margin of error = 2.5758*(0.02019)+2.5758(0.0188)
Margin of error = 0.07
Get the confidence interval
CI = p±ME
CI = (p-ME, p+ME)
CI = (0.0277-0.07, 0.277+0.07)
CI = (-0.0423, 0.0977)
Hence a 99% confidence interval for the difference between the two population proportions is -0.0423≤p≤0.0977

Step-by-step explanation:
Find the domain of fg f(x)=x+2 g(x)=1/x+2
A. All real numbers
B. All real numbers, expect 2
C. All real numbers, except-2
D. (-2,0) U [2,-2)
Answer: A. All real numbers
Step-by-step explanation:
Find fg;
f(x) * g(x) = (x + 2) * ( 1 / x + 2)
= ( x + 2) / (x + 2)
= 1
In giving 1 as the product, the domain of fg is any real number.
Lin Ying belongs to an athletic club. In 800 m races her times are normally distributed with mean 128 seconds and standard deviation
4 seconds.
(a) What is the probability of her time in an 800 being between 120 and 130 seconds?
(b) What time will she beat in 70% of her races?
Julie belongs to the same club. In 800 m races 85% of her times are less than 140 seconds and 70% are less than 135 seconds. Her times are normally distributed.
(c) Find the mean and standard deviation of Julie's times, each correct to two significant figures.
(d) What is the probability that in an 800 m race Lin Ying will beat Julie?
(e) The club has to choose one of these two athletes to enter a major competition. In order to qualify for the final rounds it is necessary to achieve a time of 114 seconds or less in the heats. Which athlete should be chosen and why?
Answer:
Nine of the times for the first race were at least 16 seconds
Step-by-step explanation:
Here we have from the scatter plot, the times are given as
Time Frequency
19 2
18 2
17 2
16 3
15 1
Therefore, total number of times that are above 16 seconds in the first race is
3 + 2 + 2 + 2 = 9
Therefore, the first option is correct

The Cyclops and Dragon both have a lot of friends that are serving as bridesmaids and groomsmen. Also, the King is acting as the officiant of the ceremony. Poly determines that the best way to organize everyone is for the officiant to stand at a vertex at the front, and to have the bride and groom stand across from each other. The bridesmaids and groomsmen will then line up so that the entire group forms a "U" shape that is symmetric about a line that passes through the point where the officiant stands.

A car rental company charges a flat rate of $19.99 for an SUV in addition to $0.79 per mile driven. Nimer's family rents an SUV from this company and drives from St. Louis to Chicago and back. If the distance from St. Louis to Chicago is 297 miles, how much did Nimer's family's pay for the car rental?
Help this is my finals
Answer:
Nimer's family paid $489.25 for the car rental
Step-by-step explanation:
Nimer's family rents an SUV from a company that charges a flat rate of $19.99 plus $0.79 per mile driven.
They travel from St. Louis to Chicago and back. The distance between these cities is 297 miles, so they drive 2*297 = 594 miles.
The total charges include a flat fee of $19.99 and the cost of 594 miles:
$19.99 + $0.79 * 594 = $19.99 + $469.26 = $489.25
Nimer's family paid $489.25 for the car rental

· Amanda has $210 in her school lunch account. She spends $35 each week on school lunches. The
equation a = 210 - 35w represents the total amount in Amanda's school lunch account a for w
weeks of purchasing lunches.
Answer:
(See step-by-step)
Step-by-step explanation:
Let’s start by making A-(X) and W-(Y). So, when substituting the variables you get x=210-35y. When x=0, the answer to the equation is 6. So, the y-intercept (when x=0) is 6 or (0,6). When y=0, the answer to the equation/x-intercept(y=0) is 210 or (210,0). The graph itself looks like the image included.
The domain, realistically, is x>=0 however on the graph itself, the domain is x= All Real Numbers. The range realistically is y>=0, but on the graph it is also All Real Numbers.
The x-intercept is the account when no weeks have passed and no money is lost (210) and the y-intercept is the maximum amount of weeks before there is no more money in the account (6).
Answer:
Blank 1: 6
Blank 2: 6
Blank 3: 0
Blank 4: 210
Blank 5: 210

What is the weight of a 32 kg child
Answer:
32000 grams
Step-by-step explanation:
The weight of a 32 kg child in pounds is 70.56 pounds.
What is Measurement unit?
A measurement unit is a standard quality used to express a physical quantity. Also it refers to the comparison between the unknown quantity with the known quantity.
Given that;
The weight of baby = 32 kg
Now,
Since, 1 kg = 2.205 pounds
So, We convert the weight of baby from kg to pounds as;
1 kg = 2.205 pounds
32 kg = 32 x 2.205 pounds
= 70.56 pounds.
Thus, The weight of a 32 kg child in pounds is 70.56 pounds.
