SAS. Sides because PN and MN are congruent as well as RN and QN. Since angle PNQ and angle MNR are vertical angles they are also congruent.
I suspect you want the area under the standard normal curve to the left of z = -0.95.
On my calculator I typed in normal cdf(-100, -0.95) and got the result 0.171.
Answer:
Step-by-step explanation:
<span>4(r+1.9)-9r=12.2
</span><span>4r + 7.6 -9r = 12.2
-5r = 12.2 - 7.6
-5r = 4.6
r = 4.6/-5
r = - 0.92</span>
Answer:
Yes because the answer to both of them is 1
Step-by-step explanation:
Let's solve your equation step-by-step.
−2x+9=7
Step 1: Subtract 9 from both sides.
−2x+9−9=7−9
−2x=−2
Step 2: Divide both sides by -2.
−2x
−2
=
