QUESTION POSTED AT 18/01/2020 - 06:46 AM .

Step-by-step explanation:

Given  : 105,000

To find : Rewrite 105,000 in scientific notation.

Solution : We have given  105,000 .

Steps to write in scientific notation :

Step 1 : If a number has n digit we move decimal point ( n-1) place to left  and to balance , multiply by .

We can see there are n = 6 in 105,000

So, we move decimal point 5 place to the left .

Then .

Therefore, .

### A school sells boxes of cookies each year for a charity fund. The data set shows the number of boxes the 10 families living on Willow Avenue buy, on average, every year. {2, 3, 2, 2, 0, 5, 2, 1, 1, 3} Does this data have negative, positive, or zero skew?

This data set has zero skew as it is symmetric.

## Step-by-step explanation:

We know that the symmetry exist in a data when the mean, median and mode of the data is same.

i.e. we are given a set of data as:

{2, 3, 2, 2, 0, 5, 2, 1, 1, 3}

• On arranging the data in increasing order we get :

0  1   1   2   2   2   2   3   3   5

Hence, the value that occur in the middle is: 2

Hence, we have Median=2

• Also, the mean is calculated as follows: Hence, Mean=2.1

• Also, the mode of the data is the most frequently occurring data point in the set.

Here 2 occurs most number of times i.e. 4 times and hence we have:

Mode=2

Now, as the Mean, Median and Mode of the data are approximately same.

Hence, we get the data is symmetric and hence has a zero skew.

### A line has a slope of - 4/5. Which ordered pairs could be points on a line that is perpendicular to this line? Check all that apply. a. (-2,0) and (2,5) b. (-4,5) and (4,-5) c. (-3,4) and (2,0) d. (1,-1) and (6,-5) e. (2,-1) and (10,9)

we know that

if two lines are perpendicular

then the product of their slopes is equal to minus one

so in this problem we have the value of m2 must be equal to we know that

The formula to calculate the slope between two points is equal to Find the slopes of each of ordered pairs and compare with m2

case a) Substitute in the formula  The slope is equal to m2

so

The ordered pair case a)  could be points on a line that is perpendicular to the given  line

case b) Substitute in the formula   The slope is not equal to m2

so

The ordered pair case b)  could not be points on a line that is perpendicular to the given  line

case c) Substitute in the formula  The slope is not equal to m2

so

The ordered pair case c)  could not be points on a line that is perpendicular to the given  line

case d) Substitute in the formula  The slope is not equal to m2

so

The ordered pair case d)  could not be points on a line that is perpendicular to the given  line

case e) Substitute in the formula   The slope is equal to m2

so

The ordered pair case e)  could be points on a line that is perpendicular to the given  line

### A water filter has the shape of an inverted right circular cone with base radius 3 meters and height 9 meters. water is being pumped into the filter at the rate of 10 meters3/sec. find the rate, in meters/sec, at which the water level is rising when the water is 3 meters deep. give 2 decimal places for your answer. type your answer in the space below. if your answer is a number less than 1, place a leading "0" before the decimal point (ex: 0.35).

The volume of a cone is
V = (1/3)πr³
We are given with radius and the height of cone, so we can solve for the radius as function of water level using ratio and proportion
3/9 = r/h
r = h/3
Substituting
V = πh³/81
Taking the derivative
dV/dt = πh²/27 dh/dt
Solving for dh/dt given
dV/dt = 10 m³/s
and
h = 3 m
dh/dt = 9.55 m/s

### Nick gets out of school at 2:25 p.m He has a 15 minute ride home on the bus. Next he goes on a 30 minute bike ride.Then he spends 55 minutes doing homework.At what time does nick finish doing his homework

This problem can easily be completed if we go through it step by step.

1. Nick has a 15 minute ride home on the bus from school at 2:25 p.m.

2:25 p.m + 15 min = 2:40 p.m.

2. He goes on a 30 minute bike ride after arriving home at 2:40 p.m.

2:40 p.m + 30 min = 3:10 p.m.

3. He spends 55 minutes doing homework at 3:10 p.m.

3:10 p.m. + 55 min = 4:05 p.m.

Ergo, Nick finished his homework at 4:05 p.m.
