Answer:
v = 2,325,457
Step-by-step explanation:
f×v= 13,573,692,509
5837×v= 13,573,692,509
v = 13,573,692,509÷5837
v = 2,325,457

Answer:
There is not sufficient evidence to conclude that the fund has moderate risk at the a = 0.01 level of significance
Step-by-step explanation:
H0: sigma= 66%
Ha:sigma < 66%
Chi square =(28-1)*2.82^2/66^2=0.049
p value =0.286
as p value>0.01 we do not can reject H0
So there is not sufficient evidence to conclude that the fund has moderate risk at the a = 0.01 level of significance
Answer:
The statement is false because ΔDEF is not a right triangle.
Step-by-step explanation:
We can figure out if this triangle is a right triangle by using the Pythagorean Theorem. The Pythagorean Theorem is <em>a² + b² = c².</em>
<em>a = 26</em>
<em>b = 27</em>
<em>c = 48</em>
Now, let's plug these numbers into the formula.
(26)² + (27)² = (48)²
676 + 729 = 2304
1405 = 2304
1405 does not equal to 2304.
So, ΔDEF is not a right triangle.
