Answer:
13/4
Step-by-step explanation:
z/w + x
(-1/2)/-2 + 3
-1/2 × -1/2 + 3
1/4 + 3
13/4
Answer:
D
Step-by-step explanation:
The margin of error represents the amount of percentage points that the real value can differ from the value given in the sample. The margin of error is ±3%, meaning that 50.6 (the sample value) ± 3% is the margin of error, resulting in a range of (47.6, 53.6) as our margin of error. Anything in that range can be the true proportion of voters that would vote for the ballot measure. As the range contains value both less than and greater than the 50% needed to pass, it is impossible to say, given the data, that the voters will vote yes or no to the ballot.
Absolute value represents a value's distance from <u>zero (0)</u> on the number line. It is expressed using a pair of <u>vertical</u> bars. In the order of operations, absolute value signs are considered like <u>parenthesis</u> and other grouping symbols. We complete the operations inside the absolute value signs <u>first</u> to get a single number. Then we take the absolute value of the number at the same time we evaluate <u>exponents</u> in the expression.
<h3>What is a number line?</h3>
A number line can be defined as a type of graph with a graduated straight line which contains both positive and negative numerical values (numbers) that are placed at equal intervals along its length.
<h3>What is an absolute value function?</h3>
An absolute value function can be defined as a type of function that consist of an algebraic expression, which placed within absolute value symbols.
<h3>The equation of an absolute value function.</h3>
Mathematically, the standard form of the equation for an absolute value function is given by:
y = a|x - h| +k.
Where:
h and k are the vertex of the graph.
<h3>The characteristics of an absolute value.</h3>
Absolute value represents a value's distance from <u>zero (0)</u> on the number line. Also, it is typically expressed using a pair of <u>vertical</u> bars. In the order of operations, absolute value signs are considered like <u>parenthesis</u> and other grouping symbols such as brackets.
Furthermore, you should complete the operations inside the absolute value signs <u>first</u> to get a single number. Then, you take the absolute value of the number at the same time when you evaluate <u>exponents</u> in the expression.
