Answer:

2z+5+5z-6=90(right angle)

Answer:

13°

Step-by-step explanation:

2z + 5° + 5z - 6° = 90° { being complementary angles }

7z = 90° + 1°

7z = 91°

z = 91° / 7

z = 13°

Hope it will help :)

What is the outlier in the following data set:<br> 15,11,10,8,9,1,8,7,5,4,2,3, and 37?
NeTakaya

Step-by-step explanation:

The steps to find an outlier:

1. Put the data in numerical order.

2. Find the median.

3. Find the medians for the top and bottom parts of the data. This divides the data into 4 equal parts.

The median with the smallest value is called Q1. The median for all the values - usually just called the median is also called Q2. The median with the largest value is Q3.

4. Subtract...Q3 - Q1. This value is the InterQuartileRange or IQR. Remember that the range means taking the largest minus the smallest. This is a special range having to do with the quartiles.

5. Multiply...1.5 * IQR

6. Take your answer from #5 and do 2 things with it. A). Subtract it from Q1 and B) Additional to Q3.

7. Look at all your data points. If any are SMALLER than Q1 - 1.5 *IQR, they are outliers. If any are LARGER than Q3 + 1.5 *IQR, they are also outliers.

For your data....the median, Q2 is

(43+38)/2 = 40.5.

Q1 = (30+26)/2 = 28.

Q3 = (54+52)/2 = 53

The IQR is 53 - 28 = 25

1.5 * IQR = 37.5

Q1 - 37.5 = 28 - 37.5 = -9.5. There is no data value less than -9.5.

Q3 + 37.5 = 53 + 37.5 = 90.5. there is no data value greater than 90.5.

My conclusion is that there are no outliers in this data.

I hope this helps!

What is the area of this
Mariulka [41]
For this, you can use the formula for the area of a circle. The formula is pi*radius*radius

Look at this figure as 1/4 of a circle. You can do this because the measure of the angle of the corner is 90 degrees, and 90 is 1/4 of 360.

Since the radius of the full circle would be 10, the area would be pi*10*10=100pi

Since this figure is 1/4 of that, the area is 25pi.

Hope this helps!

Line L is mapped onto line m by a dilation centered at the origin with a scale factor of 4.5. Line m is represented by y=3x+8 an
Charra [1.4K]

Answer:

The equation of line L is

y = 3x +  \frac{16}{9}

Step-by-step explanation:

Assuming we want to find the equation of line L.

The equation of line M is

y = 3x + 8

and it passes through (-4,-4). This line was obtained after a dilation of line M by a scale factor of 4.5.

The slope of both lines are the same.

Therefore line L also has slope

m = 3

We need to obtain the y-intercept of line L. We divide the y-intercept of line M by 4.5 to get that of line L.

b =  \frac{8}{4.5}

b =  \frac{16}{9}

The equation of line L is of the form:

y = mx + b

We substitute to get;

y = 3x +  \frac{16}{9}
