Answer:
1.) $1.07
2.) $2.25
3.) $14.20
Step-by-step explanation:
1.) Toonie = 2 CAD
CAD = USD $1.57
$1.57 - $0.50 = $1.07 (USD)
2.) $2.75 - $5 = $2.25 (USD)
3.) $20 x 4 = 80
$80 - $65.80 = $14.20 (USD)
Hope this helped!
Answer:
Step-by-step explanation:
Answer:
480.6 ; 440.5, 8 mode values
Step-by-step explanation:
Given that :
Given the data :
486, 358, 395, 759,496, 692, 353, 306
Rearranged data: 306, 353, 358, 395, 486, 496, 692, 759
The mean:
Σx/ n
n = sample size = 8
Σx = sum of all data values = 3845
Mean = 3845 / 8
Mean = 480.6
The median :
0.5(n + 1)th term
0.5(8 + 1) th term
0.5(9)th term
= 4.5term
(4th + 5th term) / 2
(395 + 486) / 2
= 440.5
The mode = most frequently occurring data value ; since all the data values have a frequency of 1, then the number of modes = 8.
Answer:
b.18
Step-by-step explanation:
18/4=4.5
Every number has factors. Some numbers share factors. To
simplify a fraction, divide the numerator and the denominator,
each separately, by the factors they share
in common. The only common factor, at the end, should be 1.
Here's an example:
![\frac{45 x^{2} }{9x} = \frac{5 x^{2} }{x} = 5](https://tex.z-dn.net/?f=%5Cfrac%7B45%20x%5E%7B2%7D%20%7D%7B9x%7D%20%3D%20%5Cfrac%7B5%20x%5E%7B2%7D%20%7D%7Bx%7D%20%3D%205)
I first divided by 9 and ten by x.
