Answer:
The value of x is 28cm.
Step-by-step explanation:
Area of a trapezium = ½h(a + b)
240 = ½×12×(12 + x)
240 = 6(12 + x)
240 = 72 + 6 x
240 - 72 = 6x
168 = 6x
168/6 = x
28 = x
b. They spent $150 to rent a bounce house for 8 hours. How much is the hourly rate for the rental?
c. If the parents spent a total of $400 on everything for the party, how much more did they spend in addition to what was spent in parts (a) and (b)?
A. Do 4.49 times 6 B. Do 150 divided by 8 C. I belive you add the answers for A and B and then subtract that from 400 and then that’s your answer for part C
Answer:
I belive it would be 1/5. ;;;
Answer:
The pythagoras's theorem is the relation between the sides of a right-angles triangle, it shows that the square of the hypotenuse of the triangle will be equal to the sum of squares of the remaining sides
hypotenuse² = perpendicular² + base²
replacing the variables with the sides of the given triangle:
x² = 15² + 8²
x² = 225 + 64
x² = 289
x = √289
x = 17 mi

Step-by-step explanation:
Answer:
An employee's score in order to qualify for increase in the salary must be higher than 95.45.
Step-by-step explanation:
Let X represent the performance score of employees.
It is provided that X follows a normal distribution with parameters μ = 82.5 and σ - 9.25.
It is provided that the office will increase salary of its top 8% employees on the basis of a performance score the office created for each employee.
That is, the probability to qualify for increase in the salary is,
P (X > x) = 0.08
⇒ P (X < x) = 0.92
⇒ P (Z < z) = 0.92
The corresponding z-value is,
z = 1.40
Compute the value of x as follows:
Thus, an employee's score in order to qualify for increase in the salary must be higher than 95.45.
