Answer:
A
Step-by-step explanation:
Use the equation y-y1=m(x-x1) and sub in the values of the provided information
Answer:
Option D) At least 3600
Step-by-step explanation:
We are given the following in the question:
The distribution of scores of individual students on the American College Testing is a bell shaped distribution that is a normal distribution.
Population standard deviation =
We want that the standard deviation of the sample should not be more than 0.1 that is the standard error should not be more than 0.1
Formula for standard error:
Thus, the sample size must be atleast 3600 so that the sample standard deviation is not more than 0.1.
Thus, the correct answer is
Option D) At least 3600
Answer:
These two triangles are congruent.
Step-by-step explanation:
You know this bc the markings on the drawing show that Angle B and Angle D are congruent. Also that AB is parallel to CD. This means that Angle BAC and Angle DCA are congruent by ALTERNATE INTERIOR ANGLES. Also, AC is congruent to itself. That makes the two triangles congruent by ANGLE-SIDE-ANGLE.
Now, you need to know that "congruent" triangles (and shapes in general) are the same size and shape. "Similar" triangles (shapes) are the same shape but not necessarily the same size.
Answer:
j
Step-by-step explanation:
Check the picture representing the movement of the aircraft.
Let B be the base, A is the first location and C is the second location.
The angles of the directions S 46° E and <span>S 55° W are as shown in the figure.
The measure of angle BAC is (90</span>°-46°)+(90°-55°)=44°+35°=79°.
According to the cosine law, we have:
