Seven baseballs are randomly selected from the production line to see if their stitching is straight. Over time, the company has found that 89.4% of all their baseballs have straight stitching. If exactly five of the seven have straight stitching, should the company stop the production line
Answer:
The probability that exactly five of the seven have straight stitching is very low only 13.47%, this means that the company should stop the production line.
Step-by-step explanation:
We are given that Seven baseballs are randomly selected from the production line to see if their stitching is straight. Over time, the company has found that 89.4% of all their baseballs have straight stitching.
Let X = Number of baseballs having straight stitching
The above situation can be represented through the binomial distribution;
[tex]P(X = r) = \binom{n}{r} \times p^{r}\times (1-p)^{n-r};x=0,1,2,3,.......[/tex]
where, n = number of samples (trials) taken = 7 baseballs
r = number of success = exactly 5
p = probbaility of success which in our question is the probability
that baseballs have straight stitching, i.e.; p = 89.4%
So, X ~ Binom(n = 7, p = 0.894)
Now, the probability that exactly five of the seven have straight stitching is given by = P(X = 5)
P(X = 5) = [tex]\binom{7}{5} \times 0.894^{5}\times (1-0.894)^{7-5}[/tex]
= [tex]21 \times 0.894^{5}\times 0.106^{2}[/tex]
= 0.1347 or 13.47%
Since the probability that exactly five of the seven have straight stitching is very low only 13.47%, this means that company should stop the production line.

Convert the inequalities into equations, and then use the substitution method to find four possible vertices in the form (x, y, z).
Answer:
For 2x + 5y < 100, x + y < 30. Vertices : (50,0) , (0,20) , (35,0) , (0,35) , (25,0)
Step-by-step explanation:
Considering inequality equations
i) 2x + 5y < 100 ;
ii) x + y < 35
Concerting them to equality conditions
i) 2x + 5y =100.
Intercepts : If y = 0, x = 50. So, (50,0). If x = 0, y = 20. So, (0,20)
ii) x + y = 35. Intercepts :
Intercepts : If y = 0, x = 35. So, (35,0). If x = 0, y = 35 So, (0,35)
Solving them as per equality (with substitution)From ii), x = 35 - y . Putting the value in i)
2 (35 - y) + 5y = 100 → 70 - 2y + 5y = 100 → 70 + 3y = 100
3y = 100 - 70 → 3y = 30 → y = 30 / 3 = 10
Putting y = 10 in ii) : x = 35 - 10 = 25
As per the 'less than' inequalities : the inner 'towards origin' area from both lines is in common shaded area.Henceworth, vertices are : (50,0) , (0,20) , (35,0) , (0,35) & intersection (25,0)

A lender will make an 80% loan-to-value loan on a property that is appraised for $72,250 and sells for $73,500. If the buyer has saved $14,450 for a down payment, how much more (if any) will he need in order to make the down payment required under the terms of this loan?
Answer:
$1250
Step-by-step explanation:
The loan can be made for up to ...
0.80 × $72,250 = $57,800
For a selling price of $73,500, the amount not funded by the loan will be ...
$73,500 -57,800 = $15,700
This is more than the buyer has saved by ...
$15,700 -14,450 = $1,250
The buyer will need $1250 in additional funds.

What does it mean if an x (input) or y (output) value doesn't make sense? What does it look like on a graph? What happens in the equation?
Answer:
It is not a function.
Step-by-step explanation:
If the x input or the y output in the given equation have no meaning or does not have any sense, then it will not form a function. We need to see if there are two of the x - intercept which are same. Then the graph will be a straight vertical line. Also the slope of the function cannot be determined.
A farmer is setting up separate pens for livestock by fencing off a rectangular area and running fence to create three parallel pens. If the farmer has to enclose a total area of 9,800 square meters, what is the shortest length of fence needed
Answer:
L(min) = 560 m
Step-by-step explanation:
Dimensions of rectangular area are: "x" and "y"
Then x*y = 9800 m²
If this area have to be divided into three parallel pens total length of fencing material would be:
L = 2*x + 4*y
And L as a function of x is
x*y = 9800 ⇒ y = 9800/x
L(x) = 2*x + 4 * 9800/x ⇒ L(x) = 2*x + 39200/x
Taking derivatives on both sides of the equation we get
L´(x) = 2 - 39200/x²
L´(x) = 0 ⇒ 2 - 39200/x² = 0
2*x² - 39200 = 0
x² = 39200 / 2 ⇒ x² = 19600
x = 140 m
And y = 39200/ 140
y = 70 m
Then minimum length of fence is:
L(min) = 2*140 + 4*70
L(min) = 280 + 280
L(min) = 560 m
Checking in the second derivative:
L´´(x) = 2*39200/x³ > 0 then we get a minimum of the function L at the point x = 140
17% of the speech team is also on the debate team rewrite this percent as a fraction in simplest form
Answer:
[tex]\frac{17}{100}[/tex]
Step-by-step explanation:
A percentage is basically another way of writing a fraction.
If we have a percentage, x%, then it's fraction will be [tex]\frac{x}{100}[/tex].
Since 17 is the percentage here, the fraction is [tex]\frac{17}{100}[/tex].
This can't be simplified any further as 17 is a prime number.

On a number line, suppose point E coordinate of -2, and EG=12. what are the possible coordinates of point G?
Answer:
-14 or 10.
Step-by-step explanation:
It is given that, on a number line, suppose point E coordinate of -2, and EG=12.
We need to find the possible coordinates of point G.
Since EG=12 it means point distance between point E and G is 12 units, therefore point G must be on 12 units left or write from point E.
If point G is 12 units left of E, then
G=-2-12=-14
If point G is 12 units right of E, then
G=-2+12=10
Therefore, the possible coordinates of point G are -14 or 10.

The quadratic equation has a general form of
[tex]ax^2+bx+c=0[/tex].
So your "b" is 9.
Hope this helps.
Answer: Answer is in the steps
Step-by-step explanation:
(2x-1)(x+5) = 0 First expand the left side by apply the distributive property twice.
(2x -1)(x+5) =0
x(2x -1) = 2x^2 -1x
5(2x -1) = 10x -5
Now rewrite them all together
2x^2 - 1x +10x -5 = 0 combine like terms on the left side.
[tex]2x^{2}[/tex] + 9x -5 = 0 a is the first leading coefficient,b is the second leading coefficient, and c is the constant.
So in this case, the value of b is 9.

Answer:
Angle NKO and Angle OKL are adjacent and complementary
Step-by-step explanation:
Adjacent - yes - they have the common vertex K and the common side KO.
Vertical - no - vertical angles are created by two intersecting lines, and angles NKO and OKL are not.
Complementary - yes - since it's given to us that JL and MN are perpendicular, that means that they intersect at 90 degree angles. This means that angles NKO and OKL add up to 90 degrees, and because complementary angles are angles that add up to 90 degrees, NKO and OKL are complementary.
Supplementary - no - supplementary angles are angles that add up to 180 degrees, and since NKO and OKL add up to 90 degrees, they can't be supplementary.
Linear Pair - no - a linear pair is a pair of angles that are adjacent and supplementary. Angles NKO and OKL are adjacent, but since they're not supplementary they can't be a linear pair.
What is the appropriate t critical value for each of the following confidence levels and sample sizes? (Round your answers to two decimal places.)
(a) 90% confidence, n = 17
(b) 90% confidence, n = 12
(c) 99% confidence, n = 24
(d) 90% confidence, n = 23
(e) 80% confidence, n = 13
(f) 95% confidence, n = 9
Answer:
(a) the critical value of t at P = 10% and 16 degrees of freedom is 1.337.
(b) the critical value of t at P = 10% and 11 degrees of freedom is 1.363.
(c) the critical value of t at P = 1% and 23 degrees of freedom is 2.500.
(d) the critical value of t at P = 10% and 22 degrees of freedom is 1.321.
(e) the critical value of t at P = 20% and 12 degrees of freedom is 0.8726.
(f) the critical value of t at P = 5% and 8 degrees of freedom is 1.860.
Step-by-step explanation:
We have to find the critical t value for each of the following confidence levels and sample sizes given below.
As we know that in the t table there are two columns. The horizontal column is represented by the symbol P which represents the level of significance and the vertical column is represented by the symbol '[tex]\nu[/tex]' which represents the degrees of freedom.
(a) So, here the level of significance = 1 - confidence level
= 1 - 0.90 = 0.10
And the degrees of freedom = n - 1
= 17 - 1 = 16
Now, in the t table, the critical value of t at P = 10% and 16 degrees of freedom is 1.337.
(b) So, here the level of significance = 1 - confidence level
= 1 - 0.90 = 0.10
And the degrees of freedom = n - 1
= 12 - 1 = 11
Now, in the t table, the critical value of t at P = 10% and 11 degrees of freedom is 1.363.
(c) So, here the level of significance = 1 - confidence level
= 1 - 0.99 = 0.01
And the degrees of freedom = n - 1
= 24 - 1 = 23
Now, in the t table, the critical value of t at P = 1% and 23 degrees of freedom is 2.500.
(d) So, here the level of significance = 1 - confidence level
= 1 - 0.90 = 0.10
And the degrees of freedom = n - 1
= 23 - 1 = 22
Now, in the t table, the critical value of t at P = 10% and 22 degrees of freedom is 1.321.
(e) So, here the level of significance = 1 - confidence level
= 1 - 0.80 = 0.20
And the degrees of freedom = n - 1
= 13 - 1 = 12
Now, in the t table, the critical value of t at P = 20% and 12 degrees of freedom is 0.8726.
(f) So, here the level of significance = 1 - confidence level
= 1 - 0.95 = 0.05
And the degrees of freedom = n - 1
= 9 - 1 = 8
Now, in the t table, the critical value of t at P = 5% and 8 degrees of freedom is 1.860.

Answer:
45 degrees
Step-by-step explanation:
We know that angle 4 equals angle 2 because corresponding angles are congruent.
So x+30 = 2x+15,
We subtract 15 from both sides,
x + 30 - 15 = 2x + 15 - 15
x + 15 = 2x
Now we subtract x from both sides,
x - x + 15 = 2x - x
15 = x
x = 15 degrees
So we plug this in angle 4,
15 + 30 = 45 degrees
