Answer:

Not necessary

Step-by-step explanation:

Given that the median score for a test was 78%. Your professor announced that anyone with a score below the median would have to retake the test. Your score was in the 65th percentile.

Since your score is in the 65th percentile, this implies that 65% of students got scores below you.

Only if you are in 50th percentile you are in median, and if your score is below 50th percentile, you will be below median.

In that case only, you have to retake the test

Here since you are in 65th percentile, you are very much above the median

and hence need not retake the test

Answer: SR ≅ UT

Step-by-step explanation:

Process of elimination:

1) RT ≅ TR doesn't help because RT and TR are the same line.

2) RU ⊥ TU doesn't help prove that ΔRST ≅ ΔTUR. It only proves that ∠TUR is a right angle  (which is already given).

3) SR ⊥ ST also doesn't help prove that ΔRST ≅ ΔTUR. It only proves that ∠RST is a right angle (which is already given).

4) The statement that SR ≅ UT tells us that ΔRST and ΔTUR are right triangles and have a hypotenuse and leg in common (both triangles share a hypotenuse,  RT, both triangles have a 90 degree angle, and SR ≅ UT). If SR ≅ UT, we can prove ΔRST ≅ ΔTUR by using the HL triangle congruence theorem.

PilotLPTM [1.2K]
Let s be the slow train, and s+22 be the faster one. Then:
976/s+s+22=4
976=8s+88
8s=888
s=111 kph as the slower train
s+22=133 kph as the faster train

-2 and 1/3 times 1 and 1/2=
torisob [31]

Answer:

-2\frac{1}{3}\times 1\frac{1}{2}=-3.5

Step-by-step explanation:

We are asked to find the product of -2\frac{1}{3} and 1\frac{1}{2}.

Upon writing our expression as a product we will get,

-2\frac{1}{3}\times 1\frac{1}{2}

Let us convert our given mixed fractions to improper fractions.

\frac{-7}{3}\times \frac{3}{2}

Upon cancelling out 3 from our given expression we will get,

\frac{-7}{2}

Upon dividing -7 by 2 we will get,

\frac{-7}{2}=-3.5

Therefore, our expression simplifies to -3.5.
