1) Try plugging in the values you have already been given into the equation L=mT+b.

2) After plugging this in, you should get 9982=m(5)+b and 10016=m(34)+b. (Remember, L equals the millimeters in this equation, and T equals the temperature.)

3) Now we use substitution to solve the rest. With the equation 9982=m(5)+b, we can change this to 9982/m(5)=b.

4) Now that we know the value for be, we can insert this into the second equation, in replacement of b: 10016=m(34)+(9982/m(5)) = 34/29. Now we know that the value m equals 34/29.

5) Replace the m values in the first equation with your newfound value: 9982=(34/29)(5)+b = 289308/29.

Answer:

m=35/29

b=289308/29

Evan bought two square rows the larger one measure 12 ft Square the smaller one had an area equal to 1/4 the area of the larger

Ghella [55]

The smallest area is:
A2 = (1/4) * (A1)
Substituting:
A2 = (1/4) * (12)
A2 = 3 feet ^ 2
Since both are squares then:
L2 = root (3)
L1 = root (12)
The relationship is:
L2 / L1 = (root (3)) / (root (12))
Rewriting:
L2 / L1 = (root (3)) / (root (3 * 4))
L2 / L1 = (root (3)) / (2raiz (3))
L2 / L1 = 1/2
Answer:
The fraction of the side length of the larger rug with a side length of the smaller one is:
L2 / L1 = 1/2

In a recent survey of 25 voters, 17 favor a new city regulation and 8 oppose it. What is the probability that in a random sample

Rasek [7]

Answer:

$P(X=2)=(6C2)(0.68)^2 (1-0.68)^{6-2}=0.0727$

Step-by-step explanation:

1) Previous concepts

The binomial distribution is a "DISCRETE probability distribution that summarizes the probability that a value will take one of two independent values under a given set of parameters. The assumptions for the binomial distribution are that there is only one outcome for each trial, each trial has the same probability of success, and each trial is mutually exclusive, or independent of each other".

2) Solution to the problem

The probability in favor of the regulation based on the recent survey is:

$p = \frac{17}{25}=0.68$

Let X the random variable of interest "Number of favor respondents about the regulation", on this case we now that:

$X \sim Binom(n=6, p=0.68)$

The probability mass function for the Binomial distribution is given as:

$P(X)=(nCx)(p)^x (1-p)^{n-x}$

Where (nCx) means combinatory and it's given by this formula:

$nCx=\frac{n!}{(n-x)! x!}$

And we want to find this probability:

$P(X=2)=(6C2)(0.68)^2 (1-0.68)^{6-2}=0.0727$

If we use X= "Number of respondednts opposed to the regulation we got the same answer", but on this case p = 1-0.68=0.32, and we want this probability:

$P(X=4)=(6C4)(0.32)^4 (1-0.32)^{6-4}=0.0727$

PLEASE HELP!! WILL REQARD A LOT

Soloha48 [4]

Answer:

17,500

Step-by-step explanation:

The problem can be written as a proportion:

hits/revenue = 1000/(£2) = x/(£35)

Multiplying by £35 gives ...

x = 1000(35/2) = 35000/2 = 17,500

17500 hits are required for revenue of £35.
