Answer:
6,5×10¹¹/1,3×10⁸= 65/13 ×10³= 5×10³=5000
<span>To find this z-score, locate the score on the table such that the area of the curve to the right is 0.37. This is similar to the 37th percentile. After locating it, you will see that the z-score is 0.3319.</span>
Answer:
The answer is D.
Step-by-step explanation:
We have to apply Discriminant Law. When a quadratic equation, ax² + bx + c = 0 has equal roots so the discriminant will be 0. Then, you have to substitute the values into the formula :
X+Y=78___1
X-Y=10____2
1+2
X+Y=78
X-Y=10
+_____
2X=88
X=44
Sub X=44 in 1
44+Y=78
Y=34
Therefore the numbers are 34,44
