Answer:
0.8
Step-by-step explanation:
Find the mean of the list:
(0.2, 0.21, 0.17, 3.22, 0.2)
The mean of a list of numbers is given by:
(sum of elements)/(number of elements)
(sum of elements) = 0.2 + 0.21 + 0.17 + 3.22 + 0.2:
(0.2 + 0.21 + 0.17 + 3.22 + 0.2)/(number of elements)
Counting, we see that the list has 5 elements:
(0.2 + 0.21 + 0.17 + 3.22 + 0.2)/5
0.2 + 0.21 + 0.17 + 3.22 + 0.2 = 4:
4/5
4/5 = 0.8:
Answer: 0.8
yes you are right, density formula is :
density = mass ÷ vol
Answer:
Step-by-step explanation:
I don't know what a tape diagram is but I can give you the equation and the answer.
Let Victor have x points
Let Maria have y points
y = x + 424
y/x = 5/3 Cross multiply
3y = 5x Divide by 3
y = 5x/3 I Could have just multiplied by x
y = x + 424
5x/3 = x + 424 Multiply both sides by 3
5x = 3x + 1272 Subtract 3x from both sides.
5x-3x = 1272 Combine the left.
2x = 1272 Divide by 2
2x/2 = 1272/2
x = 636
Victor Scored 636 points
Maria Scored 636 + 424 = 1060
The value of x is 12. 94°
<h3>How to determine the angle</h3>
From the diagram shown, we can see that the two angles are on a straight line.
It is important to note that angles on a straight line sum up to 180 degrees
Hence, we have;
(11x- 15) + 5x - 12 = 180°
collect like terms
11x + 5x - 15 - 12 = 180
Add like terms
16x - 27 = 180
16x = 180 + 27
16x = 207
Make 'x' the subject of formula
x = 207/ 16
x = 12. 94°
Thus, the value of x is 12. 94°
