Answer:
A function of the form 
, where 'm' and 'b' are real numbers, is called a <u>linear function.</u>
Step-by-step explanation:
A linear function is one in which the 
value of the function varies linearly with 'x'. When we plot a linear function on a graph, the resulting curve is always a straight line with the slope of the line being constant.
A linear function is of the form:
, where, 'm' and 'b' are real numbers.
The degree or the highest exponent of 'x' in a linear function is always equal to 1.
Therefore, a function of the form , where 'm' and 'b' are real numbers, is called a <u>linear function.</u>
Answer:
Every number that's beside a letter. in 9s, 9 is the coefficient. that goes for every single problem you have.
Answer:
The factor form is:
Step-by-step explanation:
Here we have to find the factor of the expression:
So we need to take out the common terms, as we do for finding the greatest common factors.
Now the expression that is given can be re-written as:
Next, we will find the common terms, as follows;
Now we will factorise the expression:
as follows;
So the final factor form is:
Answer:
0.3085 = 30.85% probability that the next car will be traveling less than 59 miles per hour.
Step-by-step explanation:
When the distribution is normal, we use the z-score formula.
In a set with mean 
and standard deviation 
, the zscore of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this question, we have that:
Calculate the probability that the next car will be traveling less than 59 miles per hour.
This is the pvalue of Z when X = 59. So
has a pvalue of 0.3085
0.3085 = 30.85% probability that the next car will be traveling less than 59 miles per hour.
