Answer: the length is 24m

The width is 6 m

Step-by-step explanation:

The formula for determining the perimeter of a rectangle is expressed as

Perimeter = 2(L + W)

The perimeter of the given rectangle is 60 meters. This means that

2(L + W) = 60

Dividing through by 2, it becomes

L + W = 60 /2

L + W = 30 - - - - - - - - - - - - - -1

The rectangular room is 4 times as long as it is wide. This means that

L = 4W

Substituting L = 4W into equation 1, it becomes

4W + W = 30

5W = 30

W = 30/5

W = 6

L = 4 × 6

L = 24

Answer:

6,24

Step-by-step explanation:

Perimeter = 2(L+B)

60m is perimeter

L= length =4w

W= width

Perimeter = 2(l+b)= 2(4w+w) = 60

2(5w)= 60

10w = 60

W= 60/10=6

L= 4w=4×6=24

suppose that incomes of families in Newport Harbor are normally distributed with a mean of $750,000 and a standard deviation of
denis23 [38]

Answer: 0.345

Step-by-step explanation:

Given : The incomes of families in Newport Harbor are normally distributed with Mean : \mu=\$ 750,000 and Standard deviation : \sigma= $250,000

Samples size : n=4

Let x be the random variable that represents the incomes of families in Newport Harbor.

The z-statistic :-

z=\dfrac{x-\mu}{\dfrac{\sigma}{\sqrt{n}}}

For x= $800,000

z=\dfrac{800000-750000}{\dfrac{250000}{\sqrt{4}}}=0.4

By using the standard normal distribution table , we have

The probability that the average income of these 4 families exceeds $800,000 :-

P(x>80,000)=P(z>0.4)=1-P(z\leq0.4)\\\\=1-0.6554217=0.3445783\approx0.345

Hence, the probability that the average income of these 4 families exceeds $800,000 =0.345

Triangle ABC is shown below.
Nimfa-mama [501]

The <em><u>correct answer</u></em> (though it is not one of the choices) is:

Alternate Interior Angles Theorem.

Explanation:

Alternate interior angles are angles that are inside the parallel lines and on opposite sides of the transversal.  Treating BA as a transversal, ∠DBA and ∠BAC are both inside the parallel lines and on opposite sides of BA, the transversal.  This makes them alternate interior angles, and means that they are congruent.
