Nothing times itself will equal 29, but in decimal form only is 5.38
Answer:
15. It is a function
16. It is a function
Mapping diagram is attached for reference.
Step-by-step explanation:
Mapping diagram is a set of two parallel columns.
The first column includes the 'domain'.
And the second column includes the 'range'.
A relation is a function,
if every domain (
) has only one range (
)
The given coordinates in the set form are in the form (
)
15. We observe that each '' is attached to only one ''
Therefore this relation is a function.
16. We observe that here also each '' is attached to only one ''
Therefore this relation is also a function.
Answer:
thirteen sixteenths
Step-by-step explanation:
Three eighths plus seven sixteenths equals blank
3/8 + 7/16 = ?
= (2*3)+(1*7)/16
= (6+7)/16
= 13/16
13/16 is equivalent to thirteen sixteenths
Volume of the prism = 75 cubic feet
Solution:
The image given is a rectangular prism (or) a cuboid.
Area of base = l × b = 25 square feet
Height of the prism = 3 feet
Volume of the prism = l × b × h
= (l × b) × h
= 25 × 3
= 75 cubic feet
Volume of the prism = 75 cubic feet
Hence, the volume of the prism is 75 cubic feet.
Answer: 0.8413
Step-by-step explanation:
population mean = 3
population variance = 0.03
sd (standard deviation) = √0.03
Let x = sample mean
x has a mean of 3 and sd of √0.03/√3 = √0.01 = 0.1
And we can aprox the sample mean distribution using a normal distribution
Note: this approximation maybe is not so good (n = 3)
with mean = 3 and sd = 0.1
z = (x-3)/0.1 has a standard normal distribution
P(x<3.1) = P(z<(3.1-3)/0.1) = P(z<1) =0.8413
