Answer:

Median income has not changed

Mean income has increased

Step-by-step explanation:

Initial number of houses = 6

Earning per household = $40,000

The initial mean :

$(40,000 * 6) / 6 = $40000

Initial median :

40000, 40000, 40000, 40000, 40000, 40000

= 1/2(n+1)th term,

Median = 40000

A 7th household earns 4,000,000

Mean = ((40000*6) + 4,000,000) / 7 = $605,714

Median = 1/2(n+1)th term

40000, 40000, 40000, 40000, 40000, 40000, 4000000

Median = 4th term = 40000

1 kg = 1000g

1.8 x 1000 = 1800g

The graph that represents the function y= tanx is Option A.

The graph of y =tan (x) is a periodic function that has vertical asymptotes at x = (n + 1/2)π, where n is an integer.

It oscillates between positive and   negative infinity, creating a wave-  like pattern.

It has a repeating pattern of sharp peaks and valleys, exhibiting both positive and negative slopes.

Thus, option A is the correct answer.

One way to check for a mistake in your work without redoing the cross product is to use the anti- commutative property of the cross product

One property of the cross product is that it is anti-commutative, which means that the order of the vectors matters:

v × w = - (w × v)

Using this property, we can compute w × v and compare it to the result that we got:

w × v = -(2i-j+2k)×(i+2j−3k)

= -2i×i -(-j)×2j + 2k×(-3k)

= -\(2i^2\) -\(2j^2\) -\(6k^2\)

= -2(-1) -2(-1) -6(1)

= 2

Therefore, w × v = 2(-i+2j+3k)

If the result we got, v × w=i+8j−5k, is correct, then we should have:

v × w = - (w × v)

i+8j−5k = -(-i+2j+3k)

i+8j−5k = i-2j-3k

Simplifying this equation, we get:

10j - 8k = 0

This equation is not satisfied by the vector i+8j-5k, so we can say,  that there must be a mistake in our work.

So, first they spend $100

The next week, they spend 20% less than $100, so they spent $80 that week.

The 3rd week, they spend 3/4 of $80, so they spend $60 that week.

Finally, we add the spent money from the 3 weeks (100 + 80 + 60) and get $240. I hope this helps!

Answer:

  x = -2 and x = 1/3

Step-by-step explanation:

The simple way to solve this is to enter the equation into a graphing calculator and have it show you what the zeros are.

The solutions are x = -2 and x = 1/3.

__

One way to solve this is to factor it. The product of the leading coefficient and the constant is (3)(-2) = -6. You want to find factors of this number that have a sum equal to the coefficient of the linear term: 5.

  -6 = (-1)(6) = (-2)(3) = ...

The first pair of factors listed here has a sum of 5, so we can rewrite the equation as ...

  3x^2 -x +6x -2 = 0

Factoring pairs of terms, we have ...

  x(3x -1) +2(3x -1) = 0

  (x +2)(3x -1) = 0

The solutions are the values of x that make these factors zero:

  x + 2 = 0   ⇒   x = -2

  3x -1 = 0   ⇒   x = 1/3

The solutions are x = -2 and x = 1/3.

The probability of passing at least one will be 0.70.

We know that,

Its basic premise is that something will almost certainly happen. The percentage of favorable events to the total number of occurrences.

here, we have,

Probability of passing history course = 0.59

Probability of passing math course = 0.60

Probability of passing both courses = 0.49

so, we get,

Probability of passing at least one will be

⇒ 0.59 + 0.60 – 0.49

⇒ 0.70

Answer: The mean is equal to the median.

Step-by-step explanation:

Median is the middle value of a given data set. In asymmetric distribution, the data on the left side of the median is equal to the data on the right side of the median. Therefore, the mean of that data is equal to the median of the symmetric distribution.

The current weight of the truck is obtained applying the proportions in the context of the problem.

The initial weight of the truck is given as follows:

3796 kg.

The weight removed from the truck is given as follows:

6 x 50 = 300 kg.

Hence the current weight of the truck is given as follows:

3796 - 300 = 3496 kg.

Answer: the present age of son is 15 years, and the present age of father is 45 years.

Step-by-step explanation:

Let the age of son be 'x' and that of his father be 'y'.

So according to the question, the 1st equation that can be formed will be:

y = 3(x) ->(1)

[as father's age is 3 times the age of son]

Now after 5 years:

Age of son = (x+5)

Age of father = (y+5)

So according to the question, the 2nd equation that can be formed will be:

(y+5) = 2.5×(x+5) ->(2)

[as father is now two and half times old as his son]

Substituting the value of equation (1) in (2), we get:

(3x+5) = 2.5×(x+5)

=> 3x + 5 = 2.5x + 12.5

=> 3x - 2.5x = 12.5 - 5

=> 0.5x = 7.5

=> x = 7.5/0.5 = 15

Thus, the present age of son is 15 years.

Note : we can calculate the age of father by putting the value of x in equation (1) or (2):

y = 3(x) = 3 × 15 = 45 (putting x in equation 1)

Thus, the present age of father is 45 years.

Answer:

Step-by-step explanation:

From the given information; Let's assume that  R should represent the set of all possible outcomes generated from  a bit string of length 10 .

So; as each place is fitted with either 0 or 1

\(\mathbf{|R|= 2^{10}}\)

Similarly; the event E signifies the randomly generated bit string of length 10 does not contain a 0

Now;

if  a 0 bit and a 1 bit are equally likely

The probability that a randomly generated bit string of length 10 does not contain a 0 if bits are independent and if a 0 bit and a 1 bit are equally likely is;

\(\mathbf{P(E) = \dfrac{|E|}{|R|}}\)

so ; if bits string should not contain a 0 and all other places should be occupied by 1; Then:

\(\mathbf{{|E|}=1 }\)   ; \(\mathbf{|R|= 2^{10}}\)

\(\mathbf{P(E) = \dfrac{1}{2^{10}}}\)

The volume of the cone is approximately 211.06 cubic meters.

Why is that?

Well, the formula for the volume of a cone is:

V = (1/3)πr^2h

where:

Substituting the given values, we get:V = (1/3)π(4.5m)^2(10m)

V = (1/3)π(20.25m^2)(10m)

V = (1/3)π(202.5m^3)

V = 67.5π

Using a calculator, we get:

V ≈ 211.06 cubic meters

Therefore, the volume of the cone is approximately 211.06 cubic meters.
