<em>Roberto </em><em>did not include </em><em>the </em><em>first term</em><em> of the numerator (0-2)^2 in his calculation.</em>
The mean of the data is also known as average.
Given the set of data 0, 2, 1, 2, 5
Mean = 0+2+1+2+5/5
Mean = 10/5
Mean = 2.0
To get the standard deviation, we will use the SD formula as shown:
Comparing this with Roberto's calculation, we can see that <em>Roberto </em><em>did not include </em><em>the </em><em>first term</em><em> of the numerator (0-2)^2 in his calculation.</em>

Answer: 24
Step-by-step explanation: so you calculate everything in the parenthesis fist so you do (5-1+3) to (4+3) then you do (4+3=7)
so this is how your equation is going to look 10+4÷2×7 then your going to do 4 divied by 2=2 then your going to do 2*7=14 and 14+10=24
STEP ONE- 10+4÷2(4+3)
STEP TWO- 10+4÷2×7
STEP THREE-10+2×7
STEP FOUR-10+14
ANSWER is 24
hope this helps :)
Answer:
C
Step-by-step explanation:
x≥−8
Answer:
+3.464; -3.464
Step-by-step explanation:
call A = y + 2x + 1 = 0 => y = (1 - 2x)
call B: 4y - 4(x^2) - 12x = -7
=> replace y from A to B =>
- 4(1 - 2x) - 4(x^2) - 12x = -7
- 4 - 8x - 4(x ^ 2) - 12x = -7
- -8x - 4(x ^ 2) - 12x = -7 - 4 = -11
- -4(x^2) - (8x - 12x) = -11
- -4(x^2) + 4x = -11
- -4(x^2) + 4x + 11 = 0
=> get delta Δ = (-4^2) - 4*(-4 * 11) = 192
=> Δ > 0 => got 2 No
=> x1 = 
= 
= -1.232
=> x2 = 
=
= 2.232
=> replace x from B into A
=> y1 = (1 - 2x) = (1 - 2 * -1.232) = 3.464
=> y2 = (1 - 2x) = (1 - 2 * 2.232) = - 3.464
2 waffles =3$
2x4=8 waffles (How many waffles Sage wants)
3 + 3 + 3 + 3= 12 (or 3x4)
(2) (4) (6) (8)
<u>12$ at I Scream</u>
4 waffles= 4$
4 waffles x2=8$
<u>8$ at Scoopz</u>
12-8= 4
<h3>Sage would save 4 dollars if she got 8 waffles at Scoopz.</h3>
