The slope is positive
Slope that looks like
/ is positive
\ is negative
Answer:
If two figures are similar, then the correspondent sides are related by a constant factor.
For example, if the base of one side of one of the figures has a length L, then the correspondent side of the other figure has a length k*L where k is the scale factor.
Let's start with the two left triangles.
In the smaller one the base is 5, and the base of the other triangle is 15.
Then we will have:
15 = k*5
15/5 = k = 3
The scale factor is 3.
Then we will have that:
a = scale factor times the correspondent side in the smaller triangle:
a = k*3 = 3*3 = 9
a = 9
For the other two triangles, the base of the smaller triangle is 12, while the base of the larger triangle is 20.
Then we will have the relation:
12*k = 20
k = (20/12) = 10/6 = 5/3
The scale factor is 5/3
This means that the unknown side b is given by:
b*(5/3) = 15
b = (3/5)*15 = 3*3 = 9
b = 9.
Answer: the value us 2.064
Step-by-step explanation:
To determine the t value, we would need the t distribution table. Since degree of freedom is known as 24, we would determine alpha/2
A 95% confidence level is 95/100 = 0.95
1 - alpha = 0.95
alpha = 1 - 0.95
alpha = 0.05
alpha/2 = 0.05/2 = 0.025
this is the area to the left. The area to the right 1 - 0.025 = 0.975
alpha/2 = 0.975
Looking at the t distribution table, the t value is
2.064
Answer:
The side that is labeled as 7 is 28 the side that is labeled as 5 shoud be 20 the side that is labeled as 4 should be 16
Step-by-step explanation:
Sorry I cant take a screen shot with my computer but here is the explanation it says that the scale factor is 1/4 so I just did 1/4 ÷ 7,5,and 4
there are 7 verticles on this triangular prism
