Answer:
28 degrees
Step-by-step explanation:
Because a triangle equals 180, you can subtract 90 and 34 from triangle ABE to leave you with 56 degrees for angle B.
Since CBA is a straigth line with 180 degrees, you can subtract 56 to end up with 124 degrees for angle CBE.
Since line BD bisects angle EBC (splits in half), you can divide the 124 degrees into 62 degrees.
Now that we know angle CBE equals 62 degrees, we can add the 90 degrees and subtract them from the 180 degrees of the triangle.
62+90=152
180-152=28
The value of z score for the history class test of Opal’s test score is negative one (-1).
<h3>What is normally distributed data?</h3>
Normally distributed data is the distribution of probability which is symmetric about the mean.
The mean of the data is the average value of the given data. The standard deviation of the data is the half of the difference of the highest value and mean of the data set.
The z score for the normal distributed data can be given as,
The mean value of the scores of history class is,
The standard deviation value of the scores of history class is,
Here, the test score of the Opal’s is 72. Thus the z score for her test score can be given as,
Hence, the value of z score for the history class test of Opal’s test score is negative one (-1).

The slope-intercept equation for a straight line as - 3 x + 10.
Slope refers to a number that describes both the direction and the steepness of the line.
The slope-intercept equation for a straight line is given by:
y = m x + b;
where m = the slope and b = the y-intercept.
Here, we are given that:
m = slope = -3
y- intercept = b = 10
Put it in the equation y = m x + b, we get that:
y = (-3) x + 10
y = -3 x + 10.
Therefore, we get the slope-intercept equation for a straight line as - 3 x + 10.
