Answer: x < 18

Step-by-step explanation:

x - 2 < 16

We eliminate 2 to isolate the variable, x by adding 2 to both sides. -2 + 2 = 0.

x < 18

We can test this because 17 is less than 18. Pretend x = 17

17 < 18✅

Mason subtracted 2, instead of adding 2.

In order to graph this, put an open circle at 18, and the arrow should point to the left.

Aiden says that equivalent expressions always have the same number of terms. Is Aiden correct? If he is, explain why. If he is n
ad-work [718]
No. Because for example

4+5 is 9, which has 2 terms (4,5)
BUT
3+5+1 also equals 9, which has 3 terms (3,5,1)

Both equations are equivalent to eachother, but do not have the same amount of terms. This also goes for multiplication.

10x10 is 100, which has 2 terms

BUT

5x10x2 is also 100, which has 3 terms, therefor the answer does not determine the amount of terms in an equation.

Use the pattern for (a+b)^5 to write the fourth term of (w-4z)^5
Alex Ar [27]
The fourth term of (a+b)^5 is 10a^2b^3.

For a=w, b=-4z, this is
.. 10*(w)^2*(-4z)^3
.. = -640w^2*z^3

In 2017 State A produced 779 million pounds more apples than State B. Together the two states produced 1945 pounds of apples fin
Viktor [21]

Answer: State B = 583 mp ; State A = 1,362 mp

Step-by-step explanation:

Hi, to answer this question we have to analyze the information given:

State A = produced 779 million pounds more apples than State B.

Together the two states produced 1945 million  pounds.

Using "x" as the  pounds of apples produced by State B.

  • State A = 779 + X
  • State B = X

State A + State B = 1945

Replacing with the values of both States

779+X+X =1945

779 +2X =1945

2X = 1945-779

X = 1,166 /2 =583

We have found the amount in State B.

State B = 583

Replacing on A..

State A = 779 + X = 779 + 583 = 1,362

A cable car starts off with n riders. The times between successive stops of the car are independent exponential random variables
nikitadnepr [17]

Answer:

The distribution is \frac{\lambda^{n}e^{- \lambda t}t^{n - 1}}{(n - 1)!}

Solution:

As per the question:

Total no. of riders = n

Now, suppose the T_{i} is the time between the departure of the rider i - 1 and i from the cable car.

where

T_{i} = independent exponential random variable whose rate is \lambda

The general form is given by:

T_{i} = \lambda e^{- lambda}

(a) Now, the time distribution of the last rider is given as the sum total of the time of each rider:

S_{n} = T_{1} + T_{2} + ........ + T_{n}

S_{n} = \sum_{i}^{n} T_{n}

Now, the sum of the exponential random variable with \lambda with rate \lambda is given by:

S_{n} = f(t:n, \lamda) = \frac{\lambda^{n}e^{- \lambda t}t^{n - 1}}{(n - 1)!}
