Answer: D) P(x) = -23
Step-by-step explanation:
Substitute 2 for x:
1 - 2(2)^2-3(2)^2+4(2)
Exponent
1-2(4)-3(8)+4(2)
Multiply
1-8-24+8
Combine like terms
-23

<span>With algebraic expressions, you can’t add and subtract any terms like you can add and subtract numbers. Terms must be like terms in order to combine them. So, you can’t always simplify an algebraic expression by following the order of operations. You have to use the distributive property to rewrite the expression and then combine like terms to simplify. With numeric expressions, you can either simplify inside the parentheses first or use the distributive property first.</span>
Sine = opposite / adjacent.
since the opposite and adjacent lines are used, you need to use some to solve for x.
the answer is sine.
Answer:
1300
Step-by-step explanation:
add 60x2+70+45x3
get 325
multaply times 4 because he gets this stuff then goes back and gets it 3 more times
get 1300
Answer:
The value of the test statistic is 
Step-by-step explanation:
The null hypothesis is:
The alternate hypotesis is:
Our test statistic is:
In which X is the sample mean, 
is the value tested at the null hypothesis, 
is the standard deviation(square roof of the variance) and n is the size of the sample.
In this problem, we have that:
So
The value of the test statistic is
