Answer:

(MOE) the Margin of Error will decrease by the square root of 2

Step-by-step explanation:

The Margin of Error (MOE) is an inverse function of sample size n ( more precisely of the square root of sample size ). That relation means changes in sample size ( keeping constant other variables of the distribution) will imply opposite changes in the Margin of Error. If we double the sample size increasing it from 200 up to 400,  the Margin of Error will decrease by the square root of 2

A sequence is defined recursively using the equation . If f(1)=100, what is f(6)?
Dennis_Churaev [7]

Step-by-step explanation:

A sequence is defined recursively using the equation f(n + 1) = f(n) – 8. If f(1) = 100, what is f(6) ?

Since, A sequence is defined recursively using the equation f(n + 1) = f(n) – 8. If f(1) = 100,we have to find the value of f(6).

Consider

f(n+1) = f(n)-8

Let n =1, we get

f(1+1) = f(2) = f(1) - 8 = 100-8 = 92

Let n =2, we get

f(2+1) = f(3) = f(2) - 8 = 92-8 = 84

Let n =3, we get

f(3+1) = f(4) = f(3)-8 = 84 - 8 = 76

Let n =4, we get

f(4+1) = f(5) = f(4)-8 = 76 - 8 = 68

Let n =5, we get

f(5+1) = f(6) = f(5) - 8 = 68-8 = 60

Therefore, the value of f(6) is 60.

An angle measures 38° less than the measure of its complementary angle. What is the measure of each angle?
xxMikexx [17]

Answer:

One angle is 26 degrees and the other is 64 degrees.

Step-by-step explanation:

Complementary angles add up to a total of 90 degrees. Therefore, if one of the two angles is known to be 38 degrees less, then the other angle can be calculated:

90 = (x-38) + (x)

52 = 2x

26 = x

This means that one of the angles is 26 degrees, and the other is 64 degrees.

2 Sequoya has- of a liter of apple juice which fills of her glass. How many glasses will 1 liter of apple juice fill? 3 4/6 4/3
Softa [21]

We have

1/2 liter apple juice ---- 1/3 of her glass

1-liter apple juice --- x

x is the number of glass filled with 1 liter

x=\frac{\frac{1}{3}}{\frac{1}{2}}=\frac{2}{3}

we can obtain equivalent fractions like

\frac{2}{3}=\frac{4}{6}

the answers are 2/3 and 4/6
