What is the length of the hypotenuse?
centimeters?
Answer:
Answer:
Length of leg of triangle =
Step-by-step explanation:
We are given a 45°-45°-90° triangle with hypotenuse measuring 18 cm.
Let us assume the following labeling of the diagram, as attached in the answer area.
The two angles here are equal to 45° so two sides of the triangle opposite to the equal angles will also be equal to each other i.e. it is an isosceles triangle.
i.e. The sides XY and YZ will be equal.
Let XY = YZ = x cm
It is known that in a right angled triangle, pythagorean theorem holds well.
As per pythagoream theorem:
Putting the values:
So, the length of leg of triangle =

Answer:
This isn't really a math problem since there aren't many numbers or variables provided to create an equation.

Find the measure of angle 1, 3, and 4.
Answer:
1) 60
3) 120
4) 60
Step-by-step explanation:
Angle 1 is supplementary to your known angle. Therefor, Angle 1 is 180 - 120
Angle 3 is supplementary to Angle 1 and equal to 120
Angle 4 is supplementary to Angle 3 and equal to angle 1.
if the sales-tax rate is 6%, then how much sales tax is there on a $3.79 purchase? (Round the answer to the nearest cent.)
==================================================
Work Shown:
6% = 6/100 = 0.06
6% of $3.79 = 0.06*3.79 = 0.2274 = $0.23
-----------
Notes:
0.23 dollars = 23 centsThe total bill, after tax is included, is 3.79+0.23 = 4.02 dollars.We can multiply by 1.06 as a shortcut: 1.06*3.79 = 4.0174 = 4.02 dollars; this is because 1.06 = 1 + 0.06 = 100% + 6%Which table shows exponential decay?

a data set has a mean 25 and standard deviation 5 find the z score of 39
Answer:
[tex]\boxed {\boxed {\sf z=2.8}}[/tex]
Step-by-step explanation:
The z-score helps describe a value's relationship to the mean. It tells us how many standard deviations a value is from the mean. The formula is:
[tex]z= \frac{x- \bar x}{s}[/tex]
where x is the value, x-bar is the mean, and s is the standard deviation.
We know the data set has a mean of 25 and a standard deviation of 5. The value we are finding the z score for is 39.
x= 39 x-bar= 25 s=5Substitute the values into the formula.
[tex]z= \frac{ 39-25}{5}[/tex]
Solve the numerator.
[tex]z= \frac{ 14}{5}[/tex]
[tex]z=2.8[/tex]
The z-score for 39 is 2.8. This means a value of 39 is 2.8 standard deviations greater than the mean.

Based on the amount paid per $1,000 of face value, the face value of a 10-year term insurance policy on a 24-year-old male will be a. $75,000.
Face value of insurance coverageThis can be found by the formula:
= 1,000 x (Annual premium / Amount paid per $1,000 coverage for 24 year old male for 10 year policy)
Solving gives:
= 1,000 x (359.25 / 4.79)
= 1,000 x 75
= $75,000

Below is the normal distribution curve for height (inches) of NBA basketball players.
What is the standard deviation?
Answer: standard deviation = 8
This is because mu = 75 is the mean, which is at the very exact center of this distribution. One space to the right is 83, which is 83-75 = 8 units away from the center. This distance is exactly one standard deviation. We can say "83 is one standard deviation larger than 75".
Or you could note the distance from 67 to 75 is also 8, because 75-67 = 8. Each tickmark represents stepping one standard deviation in distance.
