y=3x-16
Step-by-step explanation:
Answer:
brainest
Step-by-step explanation:
One fifth of the participants is 1/5*100=100/5=20 is the number of the participants given medicine. So the number of participants given placebo is 100-20=80.
80% of the 80 who took placebo felt improvements, so 20% of 80, which is
(20/100)*80=(2/10)*80=160/10=16 is the number of participants who took placebo and felt no improvement.
P(choosing participant who took placebo and felt no improvement)=
n(participant who took placebo and felt no improvement)/n(participants)
=16/100=0.16
Answer:
17 packs
Step-by-step explanation:
If each pack of construction paper has 495 pieces
Mrs Perkins would like to get at least 8000 pieces of construction paper
Number of Packs She will need
= Total Pieces Needed/Number of Pieces per pack
=8000/495
=
Now, 16 X 495 =7920 and this is less than the required numbers.
Therefore, She will need at least 17 packs in order to have a minimum of 8000 pieces pf construction paper
Answer:
(-2,-2)
Step-by-step explanation:
for question number 15...cordinated grid shows each equation...first equation is represented by straight line going upwards through +4 in y axis...(y=3x+4)...
point is....every point in this two lines represent a possible x and y value for each equation...and there is a point where these lines meet each other....in that point...x and y values are possible values for both equations.so answer is (-2,-2)...this cordination satisfy each pairs of equation...you can try using -2 for x in both equations and get -2 as the answer for y...that proves the point..try it for 16 quiz.good luck
