PLEASE HELP ASAP WILL GIVE BRAINLIEST TO WHOEVER ANSWERS FIRST!!!Solve the system of equations.
y = 2x + 3
2y = 4x + 10
A. Infinite Solutions
B. (-2,3)
С. (4,-1)
D. No Solution
Answer:
D. no solution
Step-by-step explanation:
substitute y = 2x + 3 in
2y = 4x + 10
gives 2(2x+3) = 4x + 10
4x - 4x = 10 - 6
therefore the equation has no solution

what is 1/2 times 5/2
Answer:
= 5/4
Step-by-step explanation:
Multiply across, so we will multiply our numerators first.
1 x 5 = 5
Then we multiply our denominators
2 x 2 = 4
Thats why your answer is 5/4
Hope this helps (:

Traveling Salesperson Suppose you are a salesperson who must visit the following 23 cities: Dallas, Tampa, Orlando, Fairbanks, Seattle, Detroit, Chicago, Houston, Arlington, Grand Rapids, Urbana, San Diego, Aspen, Little Rock, Tuscaloosa, Honolulu, New York, Ithaca, Charlottesville, Lynchville, Raleigh, Anchorage, and Los Angeles. Leave all your answers in factorial form.
a. How many possible itineraries are there that visit each city exactly once?
b. Repeat part (a) in the event that the first five stops have already been determined.
c. Repeat part (a) in the event that your itinerary must include the sequence Anchorage, Fairbanks, Seattle, Chicago, and Detroit, in that order.
Answer:
1. 23!
2. 18!
3. 19!
Step-by-step explanation:
1.
We start by the order that we were given. Dallas is the first City with los Angeles being the last.. a total of 23 states.
Dallas can be placed in any of the 23 positions.
Tampa can be placed in any of the remaining 22 positions and so on.
Such that we have
Total number of ways = 23x22x21...x1 ways
= 23!
2. If first 5 cities have been determined,
23-5 = 18 cities
We can arrange in (23-5)! Ways
= 18!
3. We consider these 5 cities to be 1 unit, so we have to arrange the remaining 18 cities plus this single unit.
Total number of ways = (18+1)!
= 19!
using binomial expansion evaluate (0.99)^6

Please please give answer for this question
Answer:
The remaining piece measures 16 m
which agrees with answer D
Step-by-step explanation:
In order to make a square of area 25 m^2, we need a square of side 5 m ,
Area of square = side^2
25 = side^2 then each side = 5 m
therefore the person needed 4 times 5 m to create the square, that is 20 m for the square. Therefore the piece that is left can be calculated with the difference:
36 m - 20 m = 16 m
The remaining piece measures 16 m
Solve for t.
45 = 5t + 45
Answer:
Submit Answer
Answer:
0
Step-by-step explanation:
45=5t+45
-45=-45
0=5t
/5
0=t
Hope this helped :)
Answer:
T=0
Step-by-step explanation:
Subtract 45 from both sides and then simplify then divide bith sides of the equation by the same term
During a test period, an experimental group of 10 vehicles using an 85 percent ethanol-gasoline mixture showed mean CO2 emissions of 240 pounds per 100 miles, with a standard deviation of 20 pounds. A control group of 14 vehicles using regular gasoline showed mean CO2 emissions of 252 pounds per 100 miles with a standard deviation of 15 pounds. A quick comparison of the sample variances suggests that the population variances are:
a. probably equal.
b. probably unequal.
c. incomparable.
Answer:
Probably unequal ( B )
Step-by-step explanation:
experimental group = 10
using 85% ethanol gasoline
mean = 240 pounds per 100 miles
standard deviation = 20 pounds
control group = 14 vehicles
using regular gasoline
mean = 252 pounds per 100 miles
standard deviation = 15 pounds
comparing the sample variance of each group shows that they are probably unequal using the equation below
Variance for a sample set of data = ∑ ( x - X ) ^2 / n - 1
where n = number of events
X = mean value
x = value of events

Help!! Find the area of the triangle.
Answer:
Area = 60.0 units²
Step-by-step explanation:
First, let's find the height of the triangle using Pythagorean Theorem:
Height = √(11² - 8²)
= √57
Height = 7.5 (nearest tenth)
✔️Find the area:
Area = ½*base*height
Base = 2*8 = 16
Height = 7.5
Plug in the values
Area = ½*16*7.5
Area = 60.0 units² (nearest tenth)
