Answer:
-12
Explanation:
We are given information to solve for 2 variables x and y. To solve this I substituted 3x for y in the equation 5x - 4y = 21
So substituting gets us 5x - 4(3x) = 21
and we can solve the equation for x
5x - 12x = 21
-7x = 21
x = -3
Now that we have found x, we can find y simply by putting it in the equation y = 3x
y = 3(-3) = -9
Once we have both variables, we can find the answer to x + y
-3 + -9 = -3 - 9 = -12
So the answer to the question
x + y = -12
Answer:
The phospholipids in the plasma membrane are arranged in two layers, called a phospholipid bilayer. The water-hating tails are on the interior of the membrane, whereas the water-loving heads point outwards, toward either the cytoplasm or the fluid that surrounds the cell.

Answer:
<em>There is no evidence to warrant rejection of the claim that the mean is 18.7 months or no evidence to test the claim that convicted burglars spend an average of 18.7 months in jail.</em>
Explanation:
<em>From the question given, we recall the following,</em>
<em>The researcher takes a random sample of 11 such cases from the court files and finds that ẋ is:</em>
<em> When s = 7.8 months and 20.6 months</em>
<em> Let Test the claim that µ = 18.7 months, when the significance level is at 0.05
</em>
<em> significance level. </em>
<em>We apply the use the traditional method of testing hypotheses</em>
<em> H0: µ = 18.7 mo. H1: µ J 18.7 mo. </em>
<em>Test statistic: t = 0.81. Critical values: t = ±2.228. Fail to reject H0. </em>
<em>Therefore,</em>
<em>There is no evidence sufficient to warrant rejection of the claim that the mean is 18.7 months</em>
