Answer:
The missing data value is 147
Step-by-step explanation:
If a point lies 3 standard deviations away from the mean, then the data point can be determined by simplifying the expression; μ±3σ. Where μ is the mean and σ the standard deviation. In this case this would be; 120±3(9)

The Montanez family cannot use more than 7250.50 gallons, this means that they can use less than or equal to 7250.50 gallons, this tells you which sign to use. The variable x can be used to describe how much water they have left to use and then you add 3,485.78 gallons to x.
x + 3485.78 ≤ 7250.50 This inequality means that the amount of water the family has yet to use added to 3485.78 gallons cannot exceed 7250.50 gallons.
Next, you simplify the inequality using the property of inequalities.
x ≤ 7250.50 - 3485.78
x ≤ 3764.72
Since 10 is smaller than 100, Garricks plant is SHORTER than Zan's plant
This means that each mm for Garrick will result in a GREATER percent error
10-8=2. His measurement was 2 mm off
100-88=12 so Zans answer was 12 mm off
2/10*100=20%
12/100*100=12%
Answers:
1. Shorter
2. Greater
3. 2 mm
4. 12 mm
5. 20%
6. 12%
Hope this helped!! :D
<span>In a baseball season:
Peter hit = 2 (x - 6)
Total = 19 hits
X= Alex’s hit
Y = Peter’s Hit
=> Y = 2(x - 6)
=> x + y = 18
Let’s start from the second given equation:
=> x + y =18
=> y = 18 – x
Now, let’s use the first given equation to solve:
=> 18 – x = 2 (x - 6)
=> 18 – x = 2x – 12
=> -3x = -30
x = 10
Now, Let’s try:
=> Y = 2(x - 6)
=> y = 2 (10 - 6)
=> y = 2 (4)
=> y = 8
Thus, Peter hit 8 and Alice hit 10.</span><span>

Answer:
The answer is below
Step-by-step explanation:
Transformation is the movement of a point from its initial location to a new location. Types of transformation is rotation, reflection, translation and dilation.
Dilation is the increase or decrease in the size of a figure by a factor (k). If k > 1, then it is a enlargement and if k < 1, it is a reduction. If a point A(x, y) is dilated by a factor k, the new point is A'(kx, ky).
Triangle DEF is a dilation of triangle ABC by a factor of 3/4. Hence the coordinates of triangle DEF is:
D(3/4, 9), E(3/4, 9/2), F(3/4, 27/4)
