Answer: The cost of milk at Target is 3 standard deviations above the mean = $3.05.
Step-by-step explanation:
Given: Mean price of a gallon of milk = $2.60
Standard deviation = $0.15
The cost of milk at Target is 3 standard deviations above the mean = Mean + Standard deviation
= $ (2.60+3(0.15))
=-$(2.60+0.45)
= $ 3.05
Hence, the cost of milk at Target is 3 standard deviations above the mean = $3.05.
Answer:
-2
Step-by-step explanation:
The point -2 on the number line is 4 units from -6 and also 4 units from 2. The midpoint M is -2.
The midpoint can be found several ways. If you draw this number line and plot points A and B, it doesn't take long to find the answer choice that is the same distance from both A and B. (4 is not even between A and B, so cannot be the midpoint.)
__
You can find the midpoint algebraically by averaging the values of A and B. Their average is their sum divided by 2, so is ...
M = (A +B)/2 = (-6 +2)/2 = -4/2
M = -2
__
Consider pairs of points that are some number of units from A toward B and the same number of units from B toward A:
(-5, 1) . . . 1 unit away
(-4, 0) . . . 2 units away
(-3, -1) . . . 3 units away
(-2, -2) . . . 4 units away from A and B. -2 is the Midpoint.
16.65-9.45=7.20
7.20/.10= 72
9.45-7.20=2.25
2.25/.05= 45

Answer:
Área: 6x2=12, 2x3=6, 10x3=30, 30+6+12=48; <u>área = 48</u>
Perímetro: 10+3+6+2+6+5+2+3+2+3=42; <u>perímetro = 42</u>
