If 6 is placed at the right end of AB, so the number is AB6.
the value of the three-digit number formed is 294 more than AB, means that if AB6 - 294 = AB <span>
</span>AB 6
- 2 9 4
AB <span>
</span>6 - 4 = B = 2 <span>
</span>If B = 2, then the tens digit is 2 - 9 (which can't be) so 12 - 9 = 3 = A <span>
</span>A = 3, and B = 2 <span>
</span><span>check: 326 - 294 = 32</span>
11.2 x 11 x 8 is 985.6
so uh- yeah i hope that helped lol
Step-by-step explanation:
step 1: how many dolphins
there are 6 sharks
sharks to dolphins is 3 to 5
3 S to 5 D
we can divide 6 (amount of sharks known) by 3, to get what a ratio of 1 is
6 ÷ 3 = 2
so 2 sharks is = 1 part or ratio
now we can times by 5 to get a ratio of 5
5 × 2 = 10
there are 10 Dolphins
Step 2: How many starfish
repeat the steps above but for the ratio 2: 7 where 2 is the Dolfin ratio and there are 10 dolphins
put in questions answer you got
By normal curve symmetry
<span>from normal table </span>
<span>we have z = 1.15 , z = -1.15 </span>
<span>z = (x - mean) / sigma </span>
<span>1.15 = (x - 150) / 25 </span>
<span>x = 178.75 </span>
<span>z = (x - mean) / sigma </span>
<span>-1.15 = (x - 150) / 25 </span>
<span>x = 121.25 </span>
<span>interval is (121.25 , 178.75) </span>
<span>Pr((121.25-150)/25 < x < (178.75-150)/25) </span>
<span>is about 75%</span>
