x + 4y = 19
Select one:
a. (7,3)
b. (4,3)
c. (-1,5)
d. (3,4)
The solution to the given equations using the elimination method is x=3 and y=4. Therefore, the answer pair is (3,4).
In order to solve this system of equations using elimination, you want to add or subtract the equations in a way that allows you to eliminate one of the variables. In this case, the y terms in the two equations are additive inverses (-4y and +4y). This means that if you add the equations together, the y variable will be eliminated.
So, let's add the two equations:
9x - 4y + x + 4y = 11 + 19
This simplifies down to 10x = 30, and when you divide both sides by 10, you get x = 3.
Next, substitute x = 3 into the second equation:
3 + 4y = 19
Solve for y by subtracting 3 from both sides and then dividing by 4. You'll find that y = 4. So the solution to the system of equations is (3,4).

Answer:
Step-by-step explanation:
Let x be the price of carton of ice cream
Let y be the number of grams in carton
Let z be price per gram.
Which means price of carton of ice cream divided by the number of grams in carton equals price per gram.
Hope this helps ;) ❤❤❤
Growth 2.63 2.57 2.67 2.50 2.47 2.38 2.25
Required:
a. Find the mean and standard deviation of both sea surface temperature x and growth y and the correlation r between x and y.
b. Find the least-squares line. The result should agree with your work in part (a) up to roundoff error. (Round your answers to three decimal places.)
c. Say in words what the numerical value of the slope tells you.
Answer:
Kindly check explanation
Step-by-step explanation:
Given the following :
Sea Surface Temperature (x) : 29.69 29.87 30.16 30.22 30.48 30.65 30.80
Growth : (y) 2.63 2.57 2.67 2.50 2.47 2.38 2.25
Mean (x) :
Σ(X) / n
n = number of observations
Mean (m1) = Σ(X) / n = 211.87 / 7 = 30.27
Standard deviation(sx) = 0.3742 (using calculator)
Mean (m2) :
Σ(y) / n = 17.47 / 7 = 2.50
Standard deviation(sy) = 0.1354 ( using calculator)
Correlation (r) :
(1/n)Σ[(x - m1) / sx] × [(y - m2) /sy]
Using calculator to save computing time :
r = - 0.8642
b. Find the least-squares line. The result should agree with your work in part (a) up to roundoff error. (Round your answers to three decimal places.)
The least square line using the regression calculator :
y = -0.31 + 11.96x
Comparing to the regression equation format :
y = mx + c
Where ;
-0.31 = intercept ; 11.96 = slope ; x = independent variable ; y = dependent variable
c. Say in words what the numerical value of the slope tells you.
For every 1° degree rise in surface temperature, growth increases by 11.96
Answer:
4pq(p³+q³)
Step-by-step explanation:
Exactly 5 game would be when 4 wins and 1 loss of a particular person
loss has to be one of the first 4 games
A wins: qp⁴ + pqp³ + p²qp² + p³qp
= qp⁴ + qp⁴ + qp⁴ + qp⁴ = 4qp⁴
B wins: pq⁴ + qpq³ + q²pq² + q³pq
= pq⁴ + pq⁴ + pq⁴ + pq⁴ = 4pq⁴
A wins or B wins:
4pq⁴ + 4qp⁴ = 4pq(q³+p³)
