Answer:

  D. insufficient data

Step-by-step explanation:

We need to know the number of assignments in each class before we can tell the probability of interest.

If we assume the same number of assignments in each class, then 25.1% of on-time assignments were in physics. We note this is not an answer choice, further confirming we have <em>insufficient data</em>.

In triangle pqr, rs=4 and qs=6. find ps
Svetradugi [14.3K]

Answer:

PS=2\sqrt{6}

Step-by-step explanation:

we are given triangle as

we know that

triangle PRS and triangle PQS are similar

so, the ratios of their sides must be equal

we get

\frac{RS}{PS}=\frac{PS}{QS}

now, we are given

RS=4

QS=6

we can plug it

\frac{4}{PS}=\frac{PS}{6}

PS^2=6\times 4

PS^2=24

now, we can solve for PS

PS=2\sqrt{6}
