Answer:
The probability that R2 is bigger than R1 is P=0.9633.
Step-by-step explanation:
We need to compute the probability that R2 is bigger than R1:
To do this, we define a new variable Das the difference between the two resistances:
Then,
As R1 and R2 are normal random variables, the properties of D are:
Then, we can calculate the z-value for D=0
Answer:
Step-by-step explanation:
Answer:
The second option, 1,008 cm²
Step-by-step explanation:
This shape has 5 sides to solve for with reguards to surface area.
Let us solve for them all.
[1 & 2 - the triangles]
12 * 9 = 108 cm²
-> I am not going to divide since we have 2 congruent triangles
[3 - the bottom side]
25 * 12 = 300 cm²
[4 - the side facing away]
25 * 9 = 225 cm²
[5 - the side facing up]
25 * 15 = 375 cm²
Now we will add them together for the total.
108 + 300 + 225 + 375 = 1,008 cm²
The surface area for the triangular prism shown is 1,008 cm².
Answer:
3:8
Step-by-step explanation:
it is 3:8 because i said it is. So basically 3:8 means 38 in sign language.
