Answer:

Hence, option A is correct.

i.e. the range is {-2,2,5,7}

Step-by-step explanation:

" The range of a function is the complete set of all possible resulting values of the dependent variable (y, usually), after we have substituted the domain "

We are given a information about the function f(x) as:

{(8, 2), (6, 5), (4, 7), (11, −2)}

Where these ordered pair represent the function f(x).

i.e. the set is (x,f(x)).

Now clearly based on the given information we could see that the range of the function f(x) is:

{2,5,7,-2}

Find the equation of the straight line through (3,4) and (5,6).
Viktor [21]

Answer:

y= x+1

Step-by-step explanation:

The equation of a line is usually written in the form of y=mx+c, where m is the gradient and c is the y-intercept.

Gradient of line = \frac{y1 - y2}{x1 - x2}

Using the above formula,

Gradient

=  \frac{6 - 4}{5 - 3}  \\  =  \frac{2}{2}   \\ = 1

Thus m=1. Substitute m=1 into the equation:

y= 1x +c

y= x +c

Susbt. a coordinate.

When x=3, y=4,

4= 3 +c

c= 4-3

c=1

Thus, the equation of the line is y= x+1.

The weights of adobe bricks used for construction are normally distributed with a mean of 3 pounds and a standard deviation of 0
dedylja [7]

Answer:  a) 0.8413, b) 0.9987.

Step-by-step explanation:

Since we have given that

Mean = 3 pounds

Standard deviation = 0.25 pounds

n = 28 bricks

So, (a) What is the probability that all the bricks in the sample exceed 2.75 pounds?

P(X>2.75)\\\\=P(z>\dfrac{2.75-3}{0.25}\\\\=P(z>\dfrac{-0.25}{0.25})\\\\=P(z>-1)\\\\=0.8413

b) What is the probability that the heaviest brick in the sample exceeds 3.75 pounds?

P(X>3.75)\\\\=P(z>\dfrac{3.75-3}{0.25})\\\\=P(z>\dfrac{0.75}{0.25})\\\\=P(z>3)\\\\=0.9987

Hence, a) 0.8413, b) 0.9987.

A scientist cools some water at a constant rate. the graph and table show how the temperature of the water changes with time.
irina1246 [14]

Answer:

C

Step-by-step explanation:

The easiest way to determine this is to realize that time is the independent variable (n) and temperature is the dependent variable (a).

From the table, we can plug in the two points (n) into n of each equation and see if that equals the temperature values (a).

<em>A little thinking would get us to plug the numbers in C first.</em>

<em>a(n)=46-(n-1)*4\\46-(5-1)*4=30</em>

<em>Works!!</em>

<em>Now, second number:</em>

<em>a(n)=46-(n-1)*4\\46-(6-1)*4=26</em>

<em>Works!!</em>

<em />

<em>Hence, C is the correct answer.</em>
