<h3>
Answer: 34%</h3>
This result is approximate.
=========================================================
Explanation:
mu = 750 = mean
sigma = 75 = standard deviation
The raw scores or x values are x = 750 and x = 825
Let's compute the z score for each x value
z = (x - mu)/sigma
z = (750 - 750)/75
z = 0
and
z = (x - mu)/sigma
z = (825 - 750)/75
z = 1
Therefore P(750 ≤ x ≤ 825) is equivalent to P(0 ≤ z ≤ 1) in this context.
Use a z score table to determine that
P(z ≤ 0) = 0.5
P(z ≤ 1) = 0.84314 approximately
So,
P(a ≤ z ≤ b) = P(z ≤ b) - P(z ≤ a)
P(0 ≤ z ≤ 1) = P(z ≤ 1) - P(z ≤ 0)
P(0 ≤ z ≤ 1) = 0.84314 - 0.5
P(0 ≤ z ≤ 1) = 0.34314 approximately
The value 0.34314 then converts to 34.314% which rounds to <u>34%</u>
Or you could use the empirical rule as shown below. The pink section on the right is marked <u>34%</u> which is approximate. This pink section is between z = 0 and z = 1.

The kinetic energy possessed by the skydiver is 14, 062. 5 Joules
<h3>What is kinetic energy?</h3>
Kinetic energy of an object is defined as the energy possessed by an object due to its motion.
It is also described as the work that is required to accelerate a body of mass from rest to its given velocity.
The formula for calculating kinetic energy is expressed as;
Kinetic energy = 1/2 mv²
Where;
- m is the mass of the object
- v is the velocity of the object
Now, substitute the values
Kinetic energy = 1/2 (45)(25)²
Find the square
Kinetic energy = 1/2 (45)(625)
Find the product
Kinetic energy = 1/2(28125)
Find the quotient
Kinetic energy = 14, 062. 5 Joules
Hence, the value is 14, 062. 5 Joules

Answer:
we must get more than 4 digs in the remaining 3 games break record of 20
Step-by-step explanation:
given data
current volleyball season = 16 digs
games left in the season = 3
previous record = 20 digs
solution
we consider here the number of digs x that must get in the remaining 3 games to break your record
so for break previous record of 20 digs, we have to get more than 20
so 16 digs must add to x to greater than 20
x + 16 ≥ 20 ...............................1
so x will be
x ≥ 20 - 16
x ≥ 4
so that we must get more than 4 digs in the remaining 3 games break record of 20
idk if you seen this but I try this
