Answer:

y = -1

Step-by-step explanation:

((3 • (5y + 2)) -  y) -  2 • (y - 3)  = 0  

Step  2  :

Equation at the end of step  2  :

 (3 • (5y + 2) -  y) -  2 • (y - 3)  = 0  

Step  3  :

Step  4  :

Pulling out like terms :

4.1     Pull out like factors :

  12y + 12  =   12 • (y + 1)  

Equation at the end of step  4  :

 12 • (y + 1)  = 0  

Step  5  :

Equations which are never true :

5.1      Solve :    12   =  0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation :

5.2      Solve  :    y+1 = 0  

Subtract  1  from both sides of the equation :  

                     y = -1

One solution was found :

                  y = -1

valentinak56 [21]

Answer:

<u>-2</u>

Step-by-step explanation:

Find two points which lie on the line :

  • Take (-2, -1) and (-1, -3)

Formula for slope (m) :

  • m = y₂ - y₁ / x₂ - x₁
  • m = -3 + 1 / -1 + 2
  • m = -2/1
  • m = <u>-2</u>

Delicious77 [7]

Answer:

Both Wolverine and James Bond will have paid the same amount after 10 months.

Step-by-step explanation:

Let x denotes the number of months after which both Wolverine and James Bond will have paid the same amount.

As Wolverine makes a $1000 down payment for a motorcycle and then pays $300 per month,

Amount paid by Wolverine in x months is equal to 1000+300x

As James Bond makes a $2500 down payment for a motorcycle and then pays $150 per month,

Amount paid by James Bond in x months is equal to 2500+150x

To find number of months after which both Wolverine and James Bond will have paid the same amount,

solve 1000+300x=2500+150x

1000+300x=2500+150x\\300x-150x=2500-1000\\150x=1500\\x=\frac{1500}{150}=10

So, both Wolverine and James Bond will have paid the same amount after 10 months.

In 2005, 0.76% of all airline flights were on-time. If we choose a simple random sample of 2000 flights, find the probability th
marissa [1.9K]

Answer:

Step-by-step explanation:

Here X no of flight that reach on time has two outcomes only and each trial is independent of the other.

Since sample size is large we approximate to normal with mean =np and variance =npq

i.e. X is N(152,19.10)

Z=\frac{x-152}{19.1} is used for converting to std normal variate

Continuity correction of 0.5 on either side of interval would be applied for x

a) P(X\geq 79%) = P(X\geq 1580)\\=P(X\geq 1579.5)\\=P(Z\geq 3.12)

=0.00

b)P(X\leq 1580)\\=P(X\leq 1580.5)\\=P(Z\leq 3.17)\\==1.00

c) p is N(0.76, sqrtpq/n)=N(0.76,0.0095)

P(p diff>0.03) =

P(Z>\frac{0.03}{0.0095} \\=P(Z>3.16)=0.00
