Answer:
4.24
Step-by-step explanation:
remember a² + b² = c²
(3*(sqrt(2))² + (3*(sqrt(2))² = 18
this would be c²
square root of this is c = 4.2426...
Answer:
2/3 because of rise over run it is a valid answer
Answer:
Angle BCD = 73 + 53 = 126 degrees
Step-by-step explanation:
<span>Solution:
We have:
length = a = 3x
</span><span>width = b = x
</span>height = h = 2x
<span>area of the base of the prism = c
</span>volume of the prism = v = 2058 cm³
Use: c = (3x)(x)
c = 3x²
Use: v = (3x²)(2x)
v = 6x³
2058 = 6x³
6x³ = 2058
x³ = 2058 / 6
x³ = 343
x = ∛343
x = 7
a = 3x
a = 3(7)
a = 21
b = x
b = 7
h = 2x
h = 2(7)
h = 14
c = 3x²
c = 3(7)²
c = 3(49)
c = 147
a = 21 cm
b = 7 cm
h = 14 cm
c = 147 cm²
Answer:
And the best answer would be:
b. 0.074.
Step-by-step explanation:
For this case we have the following info given:
represent the number of people who answer yes for the question
the sample size selected
the proportion estimated of people who answer yes
The margin of error is given by:
The confidence level is 90% and the significance would be 
and the critical value would be:
And replacing we got:
And the best answer would be:
b. 0.074.
