Which expression is NOT equivalent
to 1.24 X 0.9?
(124 x 90) x (160 x 100)

(0.124 X 9) X (10 x
(10 x 10)
(124 x 9) * (10 x 10)
Answers
The expression (124 × 9) × (1/10 × 1/10) is NOT equivalent to 1.24 × 0.9. which is the correct answer would be an option (D).
What is the expression?Expressions are defined as mathematical statements that have a minimum of two terms containing variables or numbers.
A. (124 × 90) × (1/100 × 1/100) simplifies to 1.24 × 0.9 because 124 × 90 = 11160 and 1/100 × 1/100 = 1/10000, so the expression is equivalent to (11160/10000) × 0.9 = 1.24 × 0.9.
Similarly, expressions B and C can be rearranged as (9 × 1/10) × (0.124 × 10), which is also equivalent to 1.24 × 0.9.
B. (124 × 9) × (1/100 × 1/10) simplifies to 1.24 × 0.9 because 124 × 9 = 1116 and 1/100 × 1/10 = 1/1000, so the expression is equivalent to (1116/1000) × 0.9 = 1.24 × 0.9.
C. (0.124 × 9) × (10 × 1/10) also simplifies to 1.24 × 0.9 because 0.124 × 9 = 1.116 and 10 × 1/10 = 1, so the expression is equivalent to (1.116/1) × 0.9 = 1.24 × 0.9.
However, expression D cannot be rearranged to the form 1.24 × 0.9 because it contains the factors 124 and 90, which are not equivalent to 1.24 and 0.9, respectively.
Therefore, expression D is not equivalent to 1.24 × 0.9.

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.
Answers
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

· 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.
Answers
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).

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

Downstream. In water, the direction along the stream is called downstream.
Upstream. In water, the direction against the stream is called upstream. Let the speed of a boat in still water be u km/hr and the speed of the stream be v km/hr, then. Speed downstream = (u + v) km/hr. Speed upstream = (u - v) km/hr
