In order to find the area for a strange shape, you divide it up into simpler figures. In this case, you already know that it can be divided into 4 triangles, so find the area of each triangle and add them up. Hope this helped!
Asserting a <em>cause - and - effect </em><em>relation</em><em>ship</em> with highly correlated variables may sometimes be misleading due to the presence of a possible lurking or confounding variable.
Lurking variables cause unintended or spurious association between correlated variables. In the scenario described, a possible confounding variable may be weariness or Fatigue which whereby the mother finds it easier to bottle feed as they have become psychologically disturbed and are prone to be more receptive during these period.
Hence, fatigue is a possible lurking variable in this scenario.

Answer:
basketball : 9/22
baseball : 9/12
Step-by-step explanation:
Answer:
a) H0: μEuro - μChinese = 0 vs. Ha: μEuro - μChinese > 0
b) Newborn European infants weigh more, on average, than newborn Chinese infants.
Step-by-step explanation:
<em>Null hypothesis</em> would be: infants of European descent has the same weight at birth as Chinese infants. μEuro = μChinese or μEuro - μChinese = 0
And the <em>alternative hypothesis</em> would be: infants of European descent heavier at birth than infants of Chinese descent. μEuro > μChinese or μEuro - μChinese > 0.
Because in particular infants of the European infants are considered heavier. If not, the alternative hypothesis would be μEuro ≠ μChinese
or μEuro - μChinese ≠ 0.
test a p-value of 0.001 is significant at α = .05, therefore null hypothesis is rejected in favor of alternative hypothesis Ha: μEuro - μChinese > 0, or Newborn European infants weigh more, on average, than newborn Chinese infants.
Monday : x
tuesday : 3x
wednesday : 3x - 20 = 40
thursday: 20
3x - 20 = 40
3x = 40 + 20
3x = 60
x = 60/3
x = 20
monday : 20 minutes
tuesday : 3x....3(20) = 60 minutes
wednesday : 40 minutes
thursday: 20
for a total of : 140 minutes <===
