Forced vital capacity (FVC), a standard measure of pulmonary function, is the volume of air a person can expel in 6 second. The standardized FVC follows approximately a standard normal distribution. A child is considered to have a normal long growth if his or her standardized FVC is within 1.5 standard deviation of the mean. The probability that a child is within the normal range of long growth is ______________.
Answer: the probability that a child is within the normal range of long growth is 0.8664
Step-by-step explanation:
Given that;
A child is considered to have a normal long growth if his or her standardized FVC is within 1.5 standard deviation of the mean.
he probability that a child is within the normal range of long growth = ?
so we need to find
P( -1.5 < z < 1.5)
which can also be represented as;
⇒2 × ( 0 < z < 1.5)
so we have
⇒ 2 × 0.4332
= 0.8664
Therefore the probability that a child is within the normal range of long growth is 0.8664

What is hcf of the polynomial
Answer:
the highest common factor of the polynomial is (x + 2) (x - 3)
Step-by-step explanation:
The computation of the highest common factor of the polynomial is as follows:
According to the question, the following equation is given
'[tex]x^2 - x - 6[/tex]
Now do the factorization
[tex]x^2 -3x + 2x - 6[/tex]
x(x - 3) +2 (x - 3)
(x + 2) (x - 3)
hence, the highest common factor of the polynomial is (x + 2) (x - 3)

What is the percent of decrease from 600,000 to 60,000? Write your answer using a percent sign (%).
Answer:
90%
Step-by-step explanation:
change percent to decimal = .90
600,000 x .90 = 540,000
600,000 - 540,000 = 60,000

Step-by-step explanation:
d = n^2 - 12n + 43
d = 30
30 = n^2 - 12n + 43
0 = n^2 - 12n + 13
now solve for n using quadratic formula:

Mauricio scored a total of 34.42 points in five gymnastic
events. Which number sentence shows the best way to
estimate Mauricio's score for each event?
(a) 35 = 5 = 7
(b) 35 - 7 = 5
(C) 30 = 10 = 3
(d) 40 = 10 = 4
Answer choice:
Explain how you chose your answer.
Answer:
Mauricio's score for each event is 7.
Step-by-step explanation:
Mauricio scored a total of 34.42 points in five gymnastic events.
We can round off his score as 35.
To find Mauricio's score for each event, divide total score and no of events as follows :
[tex]n=\dfrac{35}{5}\\\\=7[/tex]
Hence, Mauricio's score for each event is 7.

Select the statement that indicates that the triangles in each pair are congruent.
50 points
Answer:
D. ∆XVW ≅ ∆XBC
Step-by-step explanation:
Angle X = Angle X (vertical angles are congruent)
Angle V = angle B (corresponding angles are congruent)
Angle W = angle C (corresponding angles are congruent)
The three angels in ∆XVW are congruent to the three corresponding angles in ∆XBC.
Therefore, the statement that indicates both triangles are congruent is:
∆XVW ≅ ∆XBC

A function is initially defined by the set of coordinate pairs ((-3,7), (1,5), (4,13)). Which coordinate pair below, if added to this set, prevents the set from representing a function?
1) (2,5) 2) (5,0) 3) (-1,8) 4) (1,4)
Answer:
We conclude that if we add (1, 4) to this set, it prevents the set from representing a function.
Step-by-step explanation:
Given the initial function
{(-3, 7), (1, 5), (4, 13)}
We know that the given function indicates the relation in which each input has only one output.
i.e.
at x = -3, y = 7
at x = 1, y = 5
at x = 4,y = 13
Thus, it represents a function, becaus there is no repetitive inputs.
The only way the above function will no longer be a function we bring a point, adding of which makes the initial function having repetitive inputs.
i.e. if we add (1, 4) to the initial set, the relation will no longer be a function.
because induction of the point (1, 4) causes repetitive inputs because x = 1 is already present in the set.
so adding the point (1, 4)
{(-3, 7), (1, 4), (1, 5), (4, 13)}
Now, check the points (1, 4) and (1, 5).
It is clear that there are multiple outputs for x = 1. In other words, the input is no more a unique value as x=1 has been repeated multiple times.
Therefore, we conclude that if we add (1, 4) to this set, it prevents the set from representing a function.
