Answer:
48.2°
Step-by-step explanation:
If a 15' ladder is leaned up against a building so that the bottom of the ladder is 10' from the base of the building, what angle does the ladder make with the ground
Let the angle the ladder makes with the ground be represented by x
We solve the above question using the Trigonometric function of Cosine
cos x = Adjacent/Hypotenuse
Adjacent = 10 inches
Hypotenuse = 15 inches
Hence,
cos x = 10/15
x = arc cos (10/15)
x = 48.189685104°
Approximately = 48.2°
Therefore, the angle the ladder makes with the ground is 48.2°
y-intercept is (0,-1) and slope is 4.
Answer:
y=4x-1; y-4x=-1
Step-by-step explanation:
Not too sure what this is asking but I'm assuming you mean how to write in slope-intercept form.
y=4x-1
...or in standard for
y-4x=-1

Answer:
B don't be afraid of the rounding that took place. In this case, you pick the closest answer.
Step-by-step explanation:
Givens
r = 2
V = 60
Formula
V = 1/3 pi r^2 h
Solution
60 = 1/3 * 3.14 * 2^2 * h
60 *3 /(3.14 * 4) = h
h = 14.33 feet which is B

8, 3, 5, 5, 4, 7 Find the median, lower quartile, and upper quartile of the set of data. Use the median, lower quartile, upper quartile, lowest value, and highest value of the set to construct a box-and-whisker plot on your own sheet of paper. Use the box-and-whisker plot to find the range and the interquartile range of the set of data.
Answer:
Median: 5
Lower quartile: 4
Upper quartile: 7
Lowest value: 3
Highest value: 8
Box plot below
Step-by-step explanation:
When making a box plot, you plot the lowest value and the highest value. You make a box going from the lower quartile (in this case it's 4) to the upper quartile (7). You put a point on the median for the overall set of numbers, and you're done!
The Median is 5,The lower quartile is 4,The upper quartile is 7,The lowest value is 3,The highest value is 8.
We have given that 8, 3, 5, 5, 4, 7.
What is the median?The median is the middle number in a sorted, ascending or descending, list of numbers and can be more descriptive of that data set than the average.
We have to make a box plot, first plot the lowest value and the highest value. You make a box going from the lower quartile (in this case it's 4) to the upper quartile (7) and put a point on the median for the overall set of numbers.
