Answer:
D. false; if a = 1, b = 2, and c = 3, then 1(2 + 3) ≠ 1(2) + 2(3)
Step-by-step explanation:
A is false, because the a is being distributed/ being multiplied to all terms inside the parenthesis, and not the term b.
B is also false. There is no indicated negative signs.
C is also false because 1(1 + 1) is EQUAL to 1(1) + 1(1)
D is true.
Answer:
z=3.8196
Step-by-step explanation:
-We notice that this is a normal distribution problem.
-Given the mean is $8500, standard deviation is $1200 , and n=350, the critical z-value using alpha=0.05 is calculated as:
Hence, the test statitic is z=3.8196
Since tom has twice as much as peter and peter has half as much as Mary this shows that Tom and Mary have the same amount
Tom=$6
Mary=$6
Peter=$3
Answer:
1. LESS THAN ( 6.4... < 6.8)
2. GREATER THAN ( -6.4... > -6.8)
3. GREATER THAN (1.44 > -1.44)
4. LESS THAN (-3.1... < -3)
Step-by-step explanation:
Um, I think you have to find three pools near you and measure them to answer your question.
