Answer:
0.8041
Step-by-step explanation:
We know that
μ=72 and σ=5
and P(65<X<78)
We can determine the Z value as (X-μ)/σ
P( 65<X<78 )=P( 65-72< X-μ<78-72)


To fine the Z values:

From the standard normal tables:

to find P ( Z<-1.4)

From the standard normal tables:

Therefore


Answer:
40x+150>=400 i think
Step-by-step explanation:
40x+150>=400
40x>=250
x=6.25
Answer: y ≤ -x + 2
<u>Step-by-step explanation:</u>
There are an infinite number of possible solutions.
Plot the two points, draw any line between them such that the two points are NOT connected, then choose the inequality symbol that shades (-1, 3).
Here is one solution that satisfies the requirements. y ≤ -x + 2
Here is another: y < -x + 3
And another: y > x + 3
And one more: y ≥ x + 4
The statistics are made to be misleading in such a way that the scale is altered on the graph. So, option C is correct.
<h3>What are statistics?</h3>
Statistics is the study of the discipline that concerns the organization, collection, analysis, and presentation of data.
A hasty generalization is fallacy in which a conclusion is reached before sufficient or unbiased evidence is gathered.

Answer:
Step-by-step explanation:
If we choose chairs having odd number in the row
no of chairs from which selection is made = 10
no of chairs to be selected = 5
no of ways = 10C₅
similarly if we choose hairs having even numbers only ,
similar to above , no of ways
= 10C₅
Total no of ways
= 2 x 10C₅
= 2 x 10 x 9 x 8 x 7 x 6 / 5 x 4x3 x 2 x 1
= 504 .
