Answer:

2 km

Step-by-step explanation:

hypotenuse (h) = 10.6 km

perpendicular (p) = 10.4 km

base (b) = ?

We know by using Pythagoras theorem

b = √h² - p²

= √ (10.6)² - (10.4) ²

= √ 4.2

= 2 km

Hope it will help :)

Six less than six timesa number is 12

vovangra [49]

Six (6) less than (subtraction) six (6) times (multiplication) a number (n) is (=) 12.

6n - 6 = 12

To solve, add 6 to both sides

6n = 18 Dviide both sides by 6
n = 3

The IQR is 42.5

Step-by-step explanation:

Interquartile range is the difference of third and first quartile.

First of all we have to find the median for that purpose the data has to be arranged in ascending order. The data is already in ascending order.

As the number of values are odd

n=21

The median will be: $(\frac{n+1}{2}) th\ term$

Putting n=21

$(\frac{21+1}{2})th\ term\\=(\frac{22}{2})th\ term\\= 11th\ term$

The 11th term is 133

So median = 133

Now the data is divided into two halves

One is: 98, 100, 101, 102, 108, 109, 111,118, 129, 132

2nd is: 135, 135, 145, 146, 146, 156, 170 176, 180, 180

Q1 will be the median of first half and Q3 will be the median of 2nd half.

As now the halves contain even number of values, the medians will be the average of middle two values

For First Half:

98, 100, 101, 102, 108, 109, 111,118, 129, 132

$Q_1 = \frac{108+109}{2}\\Q_1 = \frac{217}{2}\\Q_1 = 108.5$

For Second Half:

135, 135, 145, 146, 146, 156, 170 176, 180, 180

$Q_2 = \frac{146+156}{2}\\Q_2 = \frac{302}{2}\\Q_2 = 151$

Now

Interquartile Range:

$IQR = Q_3-Q_1\\= 151-108.5\\=42.5$

Hence,

The IQR is 42.5

Pls help with this question

VARVARA [1.3K]

Answer:

it would be A

Step-by-step explanation:

the "<" (less sign) would mean B is less than A which is less than D which is less than C. if it is asking to put in the order which is greater than, there would need to be a ">" (greater sign). since there are no greater than signs, the process is flipped to be D is less than C which is less than A which is less than B meaning B is the greatest increasing likelihood, hope this helps :)
