Answer:
245 cubic inches
Step-by-step explanation:
The volume of a rectangular prism is length times width times height.
So in this case we would do, 8 * 2.5 * 12.25 to get 245. So your answer would be 245 cubic inches.
*side note*: 2 1/2 is the same thing as 2.5 and 12 1/4 is the same thing as 12.25

Find z such that 3.8% of the standard normal curve lies to the left of z. (Round your answer to two decimal places.)
Answers
Answer:
z = 1.77.
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X, which is also the area of the normal curve to the left of Z. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
Find z such that 3.8% of the standard normal curve lies to the left of z
Thus, z with a z-score of 0.038. Looking at the z-table, this is z = 1.77.

Answer:
x = 8
Step-by-step explanation:
m<PQR = (2x + 6)°
m<RPQ = (x - 7)°
m<QRS = (5x - 17)°
<PQR and <RPQ are interior angles opposite to the exterior angle <RPQ.
Therefore,
m<PQR + m<RPQ = m<QRS (Exterior Angle Theorem of a Triangle)
Substitute in the values
2x + 6 + x - 7 = 5x - 17
Add like terms
3x - 1 = 5x - 17
Collect like terms
3x - 5x = 1 - 17
-2x = -16
-2x/-2 = -16/-2
x = 8

A plane owned by Fiji Link ATR72 has three engines—a central engine and an engine on each
wing. The plane will crash because it were within the occasion that the central engine fails and
one of the two wing engines fails. The probability of disillusionment in the midst of any given
flight is 0.004 for the central engine and 0.007 for each of the wing engines. Anticipating that
the three engines work independently, what is the probability that the plane will crash in the
midst of a flight?
Answers
P(centre engine and right fail) = 0.004 x 0.007 = 0.000028
P(all three engines fail) = 0.004 x 0.007 x 0.007 = 0.000000196
P(plane will crash) = 0.000028 x 2 + 0.000000196 = 0.000056196

Answers
Answer is 42
Explaination
Consider the given problem :
Let the number be x,
This can be expressed mathematically as ,
One-third of a number written as 1/3 x
One-third of a number, decreased by six expressed as 1/3x -6
then whole expression become,
1/3x -6 = 8
Now, solving for the above expression
Adding 6 both sides, we have,
(1/3)x - 6 = 8
+6 +6
It becomes 1/3x+6-6=8 +6
1/3x = 14
Multiply both side by 3 , we get,
3* 1/3x = 14*3
x= 42
Thus, the number is 42.
