Answer:

sample mean for Urban homes=21.545

sample mean for far homes=10.164

Step-by-step explanation:

The sample mean of urban homes can be calculated as

sample mean of urban homes=xbarU=∑ui/number of values in U=∑ui/n

xbarU=6+5+11+33+4+5+80+18+35+17+23/11

xbarU=237/11

xbarU=21.545

The sample mean of farm homes can be calculated as

sample mean of farm homes=xbarF=∑fi/number of values in F=∑fi/n

xbarF=2+15+12+8+8+7+6+19+3+9.8+22/11

xbarF=111.8/11

xbarF=10.164

How many even 3-digit positive integers can be written using the digits 1,2,4,7, and 8?
N76 [4]

Looking at the question, we can see we have 5 different numbers that can go in any order.

<u>5</u> * <u>4</u> * <u>3</u>

The above is basically saying there are 5 different numbers that can be multiplied by 4 other numbers. Those 2 can be multiplied by 3 different ones, leaving us with a 3 digit positive integer.

5 * 4* 3 = 60

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 5 units,
tekilochka [14]

Answer: The value of k is 5 units.

Step-by-step explanation:

Since we have given that

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

If g(x) is obtained by shifting f(x) down by 5 units,

Then the graph of f(x) = 0.5x is replaced by the graph of g(x) = 0.5x-5

Hence, k = 5 units

Therefore, the value of k is 5 units.
