Answer:
208 cm^2
Step-by-step explanation:
(6x8x0.5x2) + (4x8x2) + (10x3) + (8x3) + (10x3) + (4x3) = 208
Answer:
= -120a³b²c²
Step-by-step explanation:
10ac * 6ab * -2abc
10*6*-2 = -120
ac * ab * abc = a*a*a *b*b*c*c = a³b²c²
then:
10ac * 6ab * -2abc = -120* a³b²c²
= -120a³b²c²
Answer:
Step-by-step explanation:
(a)
perfect positive correlation.
As x increases by 1, y increases by 1
y is 1 times x
equation: y = x
(b)
perfect negative correlation.
As x increases by 1, y decreases by -4
y is
times x
equation: y = -4x
Answer:
Null hypothesis (
): The birth weight of the first born of identical twins is the same as the birth weight of the second born.
Alternative hypothesis (
): The birth weight of the first born of identical twins is higher than the second born.
Step-by-step explanation:
Please note that the null hypothesis is the hypothesis we always want to reject or prove to be false. Hence in this study, the objective of the study is clearly stated that the researcher want to determine whether the twin born first tends to weigh more than the twin born second.
Therefore, the null hypothesis we assume that the weight of the identical twins is the same regardless of who come first or last., while the alternative hypothesis is constructed or stated to answer the research objective.
