Imagine you conducted a study to look at the association between whether an expectant mother eats breakfast (or not) and the gen

der of her baby. Cramér's V = .22. How would you interpret this value? (Hint: Cramér's V can range between 0 and 1.) There was a small to medium association between baby gender and whether the mother ate breakfast every day. 22% of the variation in frequency counts of baby gender (boy or girl) can be explained by whether or not the mother ate breakfast every day. 2.2% of the variation in frequency counts of baby gender (boy or girl) can be explained by whether or not the mother ate breakfast every day. There is a medium to large association between the gender of the baby and whether or not the mother ate breakfast every day.

Which of these polynomial equations is of least degree and has -1, 2, and 4 as three of its roots?
kvasek [131]

Answer:

x^3 - 5 x^2 + 2 x + 8 = 0

Step-by-step explanation:

Solve for x over the real numbers:

x^3 - 5 x^2 + 2 x + 8 = 0

The left hand side factors into a product with three terms:

(x - 4) (x - 2) (x + 1) = 0

Split into three equations:

x - 4 = 0 or x - 2 = 0 or x + 1 = 0

Add 4 to both sides:

x = 4 or x - 2 = 0 or x + 1 = 0

Add 2 to both sides:

x = 4 or x = 2 or x + 1 = 0

Subtract 1 from both sides:

Answer: x = 4 or x = 2 or x = -1

The function is given f(x)=2^x+3.

Now let's solve for f(-2).

f(-2)=2^{-2}+3

Rule of negative exponent: x^{-1}=\frac{1}{x^1}.

f(-2)=\frac{1}{2^2}+3

f(-2)=\frac{1}{4}+\frac{3}{1}

Rule for sum of fractions: \frac{a}{b}+\frac{c}{d}=\frac{ad+bc}{bd}.

f(-2)=\frac{13}{4}

And the result is:

f(-2)=\boxed{\frac{13}{4}=3.25}
