To shift a graph down by two units, -2 must beg added to the function.

Since g(x)=0.5x-k already, k=2, because it is already specified that the constant will be subtracted.

Answer: The value of k is 2.

Step-by-step explanation:

Given : The graph of $f(x)=(0.5)x$ is replaced by the graph of $g(x)=0.5)x-k.$

If g(x) is obtained by shifting f(x) down by 2 units, then $g(x)=(0.5)-2$

[since f(x)shifted down down by 2 , so only the value of dependent variable effect]

When we compare both functions of g(x), we found that k=2.

Hence, the value of k is 2.

Times for a surgical procedure are normally distributed. There are two methods. Method A has a mean of 33 minutes and a standard

lilavasa [31]

Answer:

Method A.

Step-by-step explanation:

For solving this question we need to find out the z-scores for both methods,

Since, the z-score formula is,

$z=\frac{x-\mu}{\sigma}$

Where, $\mu$ is mean,

$\sigma$ is standard deviation,

Given,

For method A,

$\mu = 33$

$\sigma=8$

Thus, the z score for 34 is,

$z_1=\frac{34-33}{8}=0.125$

While, for method B,

$\mu = 37$

$\sigma = 4$

Thus, the z score for 34 is,

$z_2=\frac{34-37}{4}=-0.75$ ,

Since, $z_1 > z_2$

Hence, method A is preferred if the procedure must be completed within 34 minutes.

What is the range of the function represented by the table? 2/2.5 4/5.0 6/7.5 8/10.00 10/12.5

pishuonlain [190]

Answer:

{2.5, 5.0, 7.5, 10.0, 12.5}

Step-by-step explanation:

Next time, would you please type in the table vertically:

2 2.5

4 5.0

6 7.5

and so on.

The range consists of all the possible numerical outputs of the function for given inputs: {2.5, 5.0, 7.5, 10.0, 12.5}. Without knowing the outputs for other, unknown inputs, we cannot be more detailed in specifying the range.

Liam's breakfast was an egg and cheese biscuit with a carton of milk. He spent a total of $5.65. Finn spent $7.65 on an egg and

ruslelena [56]

Answer:

An egg and cheese biscuit was $3.65.

Step-by-step explanation:

Liam's breakfast was:

$P = E + C + M$

Where:

P: total price

E: egg

C: cheese biscuit

M: carton of milk

$P = E + C + M$

$5.65 = E + C + M$ (1)

Now, Finn's breakfast was:

$P = E + C + 2*M$

$7.65 = E + C + 2*M$ (2)

By subtracting equation (2) from (1) we have:

$7.65 - 5.65 = 2M - M$

$M = 2$

Hence, the price of a carton of milk is $2, so by entering this value into equation (1) we can find the price of an egg and cheese biscuit:

$5.65 = E + C + M$

$5.65 - 2 = E + C$

$E + C = 3.65$

Therefore, an egg and cheese biscuit was $3.65.

I hope it helps you!
