C= 40c
A singing competition is auditioning 40 contestants each hour. For every value of h it will add 40 which will equal the total number of contestants that audition in h hours.
Check: 40(2)=80 (Correct)
40(3)=120 (Correct)
And so on.
Answer:
<u>Lower Upper Frequency</u>
1 6 2
7 12 4
13 18 7
19 24 1
25 30 4
Step-by-step explanation:
We sort the given data to get: 1,4,8,8,9,10,13,14,15,15,15,16,18,24,25,25,27,29
The range is 29-1=28
Class width=28/5=5.6
We round up to get 6
The lowest value is 1. Our lower class limits are:
1
7
13
19
25
The upper class limits are:
6
12
18
24
30
Now our frequency table is:
<u>Amount | Frequency</u>
1-6 2
7-12 4
13-18 7
19-24 1
25-30 4

Answer:
x = 15
Step-by-step explanation:
Given
See attachment
Required
Find x
The figure in the attachment is a quadrilateral and the angles in a quadrilateral add up to 360.
So, we have:
90 + 6x + 5+ 10x - 40 + 4x + 5 = 360
Collect like terms
6x + 10x + 4x = 360 - 90 - 5 + 40 - 5
20x = 300
Divide both sides by 20
x = 15
Hence, the value of x is 15
Answer:
-63
Step-by-step explanation:
Write the problem as a mathematical expression.
Simplify 4−4−8 to substitute in f(x)=−x^2+1
Subtract 4 from 4
Subtract 8 from 0
Replace the variable x with −
8 in the expression
Simplify
Answer = -63
