Which logarithmic graph can be used to approximate the value of y in the equation 3y = 7?
1 answer:
We have that
3^y = 7
applying log both members
log(3^y)=log 7
y*log 3=log 7
y=log 7/log 3
using the <span>logarithmic graph of y=log x
</span><span>I graphically determine the values for x = 3 and x = 7
</span><span>
see the attached figure
for x=3
log 3=0.48
for x=7
log 7=0.85
therefore
</span>y=log 7/log 3-----> y=0.85/0.48-----> y=1.77
<span>
the answer is
the </span><span>approximate value of y is 1.77</span>

We can first add up the cards so we know how many we have in all:
16 + 16 + 18 = 50 cards
We can do this a little bit easier if we get the "16"-cards in one number total.
16 + 16 = 32
= 32 x 2 = 
50 x 2
= 64 : 2 = 32 %
100
We did just divide the % of two types cards on 2, so we get the %-chance of 1 type card.
I am not quite sure, but I think that 32 % is the correct answer.
