Here is a list of numbers: 12, 13, 19, 16 ,32, 15, 13.a)work out the range of the numbers in the list.
b)work out the mean of the numbers in the list

Answers

Answer 1
Answer:

The range of the numbers in the list is 20 and the mean of the numbers in the list is 17.14

Work out the range of the numbers in the list.

To calculate the range of the numbers in the list, subtract the smallest number from the largest number:

Range = Largest number - Smallest number

Range = 32 - 12 = 20

Work out the mean of the numbers in the list

To calculate the mean of the numbers in the list, add all the numbers and divide by the total number of numbers:

Mean = (12 + 13 + 19 + 16 + 32 + 15 + 13) / 7 = 120 / 7

Mean ≈ 17.14

Answers

d=5+n
0.1(5+n)+0.05n=1.7
0.5+0.15n=1.7
0.15n=1.2
n=8
d=13
therefore 8 nickles and 13 dimes.

B)It is rational and equal to 4.
C)It is irrational and equal to 3 multiplied by the square root of 2.
D) It is irrational and equal to 4 multiplied by the square root of 2.

Answers

Given:
circular cardboard with an area between 154 in² and 616 in²

Area of a circle = πr²
154 in² = 3.14 * r²                     616 in² = 3.14 * r²
154 in² / 3.14 = r²                      616 in² / 3.14 = r²
49 in² = r²                                  196 in² = r²
√49 in² = √r²                             √196 in² = √r²
7 = r                                          14 in = r

Radius is between 7 inches and 14 inches. ⇒ A) 7 < r < 14

√18 + √2 = √9 *2 + √2 = 3√2 + √2 = (3+1) √2  = 4√2

D) It is irrational and equal to 4 multiplied by the square root of 2.

(URGENT) WILL GIVE BRAINIESTIn Exercises 5−7, use your new conjectures to arrange the unknown measures in order from greatest to least.

Answers

Answer:

5. a,c,b

6. a,b,c

7. v,z,y,w,x

Step-by-step explanation:

5. Given are the measure of sides as 28,17 and 15. The corresponding angles are 'a', 'c' and 'b'.

Using the conjecture: The angle opposite to the greatest side is largest.

Thus for the sides  28,17 and 15. The corresponding angles 'a', 'c' and 'b' are in order from greatest to least.

6. Given are the angles 30, 72 and 75( angles of an isosceles triangle).

Using the conjecture: The angle opposite to the greatest side is largest.

We observe

'a' is corresponding to angle 75°

'b' is corresponding to angle 72° and

'c' is corresponding to angle 36°

Thus a,b,c are the order from greatest to least.

7. Given

'v' is corresponding to angle 122° [180-(30+28)]

'w' is corresponding to angle 42°

'x' is corresponding to angle 34°

'y' is included in three dimensional angle

'z' is included in three dimensional angle

Such that z>y

Thus the order from greatest to least is v,z,y,w,x
