Answer:
Simplifying
8x + -4y = 24
Solving
8x + -4y = 24
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '4y' to each side of the equation.
8x + -4y + 4y = 24 + 4y
Combine like terms: -4y + 4y = 0
8x + 0 = 24 + 4y
8x = 24 + 4y
Divide each side by '8'.
x = 3 + 0.5y
Simplifying
x = 3 + 0.5y
God bless you and have a beautiful rest of your day!
Answer:
12
Step-by-step explanation:
for g(3) replace x with 3 and for f(4) since f(x) is a constant function the value won't change so you put 2 then add both functions up
g(3) = 3^2 + 1 ➡ 10
f(4)= 2
10 + 2 = 12
It depends on what the level of significance (alpha) is.
Since alpha is not stated, I'll assume that alpha = 0.05 by default.
Because the p-value is smaller than alpha, we reject the null hypothesis.
Therefore, we conclude that the alternative hypothesis is correct and the proportion of heads is greater than 0.5
