Answer:
Option C. 15^2 + 20^2 = 25^2
Step-by-step explanation:from the question, we obtained the following:
The sides = 25, 15, 20
Since it is a right angle triangle, 25 is the longest side. Therefore their relationship is:
15^2 + 20^2 = 25^2
Answer:
We conclude that average reflectometer reading for a new type of paint is greater than 20
Step-by-step explanation:
We are given the following in the question:
Population mean, μ = 20
Sample size, n = 13
Alpha, α = 0.05
First, we design the null and the alternate hypothesis
Formula:
Degree of freedom = n - 1 = 13 - 1 = 12
Now, we calculate the p-value with the help of standard table.
P-value = 0.004
Since, the p-value is less than the significance level, we fail to accept the null hypothesis and reject it.
Thus, there is enough evidence to support that average reflectometer reading for a new type of paint is greater than 20
B or D, I forgot whether the open circle or the circle is the equal to one, if I had to guess I'd say B
Step-by-step explanation:
CONGRUENT TRIANGLES : Two triangles are said to be congruent if they have same sides and exactly same angles.
Now, any two triangles can be congruent by any of the following 3 properties:
1) SIDE SIDE SIDE (SSS) : Here three sides of triangle 1 is equal to the three sides of the triangle 2.
2) SIDE ANGLE SIDE (SAS) : Here two sides and including angle of triangle 1 is equal to the two sides and including angle of the triangle 2.
3) ANGLE SIDE ANGLE (ASA) : Here two angles and including side of triangle 1 is equal to two angles and including side of the triangle 2.
4) ANGLE ANGLE SIDE (AAS) : Here two angle and one side of triangle 1 is equal to the two angles and one side of the triangle 2.
