Answer:
6cm is the missing length
Step-by-step explanation:
See the 10cm and the 4cm?
If you look at in a way if you added 6 more centimeters to the 4cm it would be 10, leaving 6cm as the missing length.
Answer:
c
Step-by-step explanation:
when we add 0 to x ,it remains x.
x+0=x
0 is additive identity.
Answer:
Percentage of students who scored greater than 700 = 97.72%
Step-by-step explanation:
We are given that the College Board originally scaled SAT scores so that the scores for each section were approximately normally distributed with a mean of 500 and a standard deviation of 100.
Let X = percentage of students who scored greater than 700.
Since, X ~ N(
)
The z probability is given by;
Z = 
~ N(0,1) where, 
= 500 and 
= 100
So, P(percentage of students who scored greater than 700) = P(X > 700)
P(X > 700) = P( < 
) = P(Z < 2) = 0.97725 or 97.72% Therefore, percentage of students who scored greater than 700 is 97.72%.
The area of the trapezoid is 45 cm²
Since Seema runs 5 more miles than Padma, we could find how long Padma runs by subtracting 5 miles from the amount of miles that Seema runs. If P is equal to the distance that Padma runs, our equation is:
P = 17-5 = 12 miles.
