Solve the system of equation by substitution

Mathematics

otez555 [7]3 years ago

Ah, good ol' substitution. You need to take the phrase y+2 and replace every x with it. Then solve for y.

y=(y+2)^3-4(y+2)^2-6(y+2)+8

Answer:

161 6/72

Step-by-step explanation:

50 5/8 plus 50 5/8 = 100 10/8 = 101 2/8

30 2/9 + 30 2/9 = 60 4/9

add them together which comes out to 161 6/?

Use LCM or least common multipule and it should come out to 161 6/72

Evaluate the line integral, where C is the given curve. (x + 4y) dx + x2 dy, C C consists of line segments from (0, 0) to (4, 1)
zubka84 [21]

Parameterize the line segments (call them C_1 and C_2, respectively, by

\vec r_1(t)=(1-t)(0,0)+t(4,1)=(4t,t)

\vec r_2(t)=(1-t)(4,1)+t(5,0)=(4+t,1-t)

both with 0\le t\le1. Then

\displaystyle\int_C(x+4y)\,\mathrm dx+x^2\,\mathrm dy

=\displaystyle\int_0^1\bigg((4t+4t)(4)+(4t)^2(1)\bigg)\,\mathrm dt+\int_0^1\bigg((4+t+4(1-t))(1)+(4+t)^2(-1)\bigg)\,\mathrm dt

=\displaystyle\int_0^115t^2+21t-8\,\mathrm dt=\boxed{\frac{15}2}

Required information Section 01.02 Exercise 14 - Effects of changing data values on mean, median, and standard deviation There a
Nutka1998 [239]

Answer:

  • Mean will Increase .
  • Median remains unchanged.
  • Standard deviation will increase.

Step-by-step explanation:

We are given that there are 14 employees in a particular division of a company and their salaries have a mean of $70,000, a median of $55,000, and a standard deviation of $20,000.

And also the largest number on the list is $100,000 but By accident, this number is changed to $1,000,000.

Now we have to analyse the Effect of this change in data values on mean, median, and standard deviation.

  • Mean will get affected because $1,000,000 is a very huge value as compared to $100,000 and is considered to be an outlier and we know that mean is affected by outliers as mean will change to $134285.7143 after replacing $100,000 with $1,000,000 .
  • Median will not get affected as median the middle most value in the data set and since $1,000,000 is considered to be an outlier so median remain unchanged at $55,000 .
  • Standard Deviation will also get affected as due to outlier value in the data set the numerator value will increase very much and due to which standard deviation will also increase.

sergeinik [125]
The answer is 28.
Check: 28-12= 16
1/4 of 16= 4
3/4 of 16= 12
so Carmen takes 3/4 more time of the trip to the market when she return s home.
