8/25 is the probability that more than 8 of them are strikes.
Lets simplify the problem,
We are given that a softball pitcher has a 0.507 probability of throwing a strike for each pitch. Also, the softball pitcher throws 15 pitches.
The above situation can be represented through Binomial distribution;
P(X = r) = 0,1,2,3,,.....
where, n = number of trials (samples) taken = 15 pitches
r = number of success = more than 8
p = probability of success which in our question is probability of
Throwing a strike for each pitch = 0.507
LET X = Number of strikes
So, it means X ~ n = 15, p = 0.507
So, Probability that more than 8 of them are strikes = P(X > 8)
P(X > 8) = P(X = 9) + P(X = 10) + P(X = 11) + P(X = 12) + P(X = 13) + P(X = 14) + P(X = 15)
After putting the values in it we get,
P = 0.323
P= 8/25 approx
8/25 is the probability that more than 8 of them are strikes.

{y = -4x - 6
{-4x - y - 6 = 0
y = -4x - 6 and -4x - y - 6 = 0 are both representations of the same linear equation.
The first equation, y = -4x - 6, is in slope-intercept form, where y is the dependent variable, x is the independent variable, -4 is the slope and -6 is the y-intercept. This means that when you graph this equation, the slope of the line will be -4 and the y-intercept will be -6.
The second equation, -4x - y - 6 = 0, is in standard form, where the variables are on one side of the equation and the constants are on the other side. To get this equation, you can move the y term to the other side by adding y to both sides, and then move the constants to the other side by adding 6 to both sides.
Both equations represent the same line. They are just in different forms, one is in slope-intercept form and the other is in standard form.
Answer:
infinite number of solutions
Step-by-step explanation:
y = - 4x - 6 → (1)
- 4x - y - 6 = 0 → (2)
substitute y = - 4x - 6 into (2)
- 4x - (- 4x - 6) - 6 = 0 ← distribute parenthesis and simplify left side
- 4x + 4x + 6 - 6 = 0
0 = 0 ← true statement
when both sides have the same numeric value
this indicates the system has an infinite number of solutions.

find a positive and a negative co-terminal of each angle 111 degrees
The Positive co-terminal angle is 471° and negative co-terminal angle is -249°.
What is co-terminal angle?Co-terminal angles have different degrees, but they all have their initial side on the positive x -axis (it goes this way →) and share the same terminal side hence the term "co-terminal." Co-terminal angles differ by 360°. Therefore, we only need to add/subtract 360° to get our positive/negative co-terminal angle measures.
Here the given angle is ,
=> 111°
Positive co-terminal angle:
=> 111°+360°=471°
Now negative co-terminal angle is ,
=> -(360°-111°)
=> - 249°
Hence the Positive co-terminal angle is 471° and negative co-terminal angle is -249°.

How to determine the linear function f with the given values.From the question, we have the following parameters that can be used in our computation:
f(0) = 2 , f(-2) = -2
A linear equation can be represented as
f(x) = mx + c
Substitute the known values in the above equation, so, we have the following representation
m * 0 + c = 2
m * -2 + c = -2
Solving 0 * x + c = 2, we have
c = 2
So, we have
m * -2 + c = -2
This gives
-2 * m + 2 = -2
Evaluate the like terms in the above equation
So, we have the following representation
-2m = -4
Divide both sides of the equation by -2
So, we have
m = 2
Substitute the known values in the equation f(x) = mx + c, so, we have the following representation
f(x) = 2x + 2

Which measure of center should Raul use to calculate his overall performance if he hits a line drive to the outfield on each pitch?
Since the distribution of the 10 distances is not uniform, Raul should use the median to determine his total performance.
What is median?The median is the value that divides a data sample, a population, or a probability distribution's upper and lower halves in statistics and probability theory.
It could be referred to as "the middle" value for a data set.
The fundamental difference between the mean and the median when describing data is that the median is more representative of the "normal" value because it is not skewed by a tiny fraction of exceptionally big or small values.
Due to the fact that income distribution can be very skewed, the median income, for instance, might be a better indicator of what is considered a "normal" income.
Given that it is the most resilient statistic, the median is crucial to strong statistics.

Solve the following problem
Note that the area of the above triangle is given as: 42.
This is solved using the SOH CAH TOA Rule and the Formula of the Right Angled Triangle
The hypotenuse is the longest side of a right triangle, a "opposite" side is the one across from a given angle, and a "adjacent" side is the one close to a given angle. Right triangle sides are described using specific terminology. A right triangle's hypotenuse is always the side opposite the right angle.
To find the area of the triangle we must obtain, the Base and the Height, that is FD and A F.
Note that we have
∠F = 90°
∠D = 30°
Since the sum of angles in a Δ = 180°,
∠A = 180 - (90 + 30)
∠A = 60°
To find the area of the triangle we must obtain, the Base and the Height, that is F D and A F.
To obtain F D, we must use the Sine rule which states:
Sine θ = O/H; that is
Sin ∠A = F D/AD
Sin 60° = F D/14
0.86602540378 = FD/14
F D = 14 * 0.86602540378
F D = 12.1243556529
F D [tex]\approx[/tex] 12. 12
Using the above Cos Rule (CAH) we can find the Adjacent Side (that is height). Thus
Cos A = A F/AD
Cos 60° = A F/14
0.5 = A F/14; multiply both sides by 14
A F = 0.5 * 14
A F = 7
Now we have Adjacent Side (Height) = 7; and the Opposite Side (Base) = 12.12
The area of the Triangle according to the Pythagorean Rule is:
1/2 B * H
= 1/2 * 12.12 * 7
= 42.42
Thus the Area of the above triangle [tex]\approx[/tex] 42

A car producer stocks three types of tires: a, b, and c. Let p(a) = 0. 40, p(b) = 0. 15 and p(c) = 0. 45. The percentage of defective tires is 2%, 1% and 5%, respectively. Someone picks a tire off the shelf at random and it is brand a. If you want to know the probability that it is a defective tire (event d), which formula would you use?.
The formula which we would use to know the probability that it is a defective tire of brand A is P(A|D) = P(D|A)P(A) / P(D). P(D) is the probability that a tire produced is defective.
What is probability?Probability is a numerical description of how possible an event to happen. Tha value of probability is between 0 to 1. Zero probability means something is impossible to happen. Probability 1 shows certainty.
A car producer stocks three types of tires. They are A, B, and C.
P(A) = 0.40P(B) = 0.15P(C) = 0.45The percentage of defective tires is 2%, 1% and 5%, respectively. Someone picks a tire randomly and he gets brand A.
Find the formula to know the probability that it is a defective tire!
The options are
a) P(A|D) = P(D|A)P(A) / P(D)
b) P(D|A) = P(A|D)P(D) / P(A)
c) P(A|D)= P(D/A)P(D) / P(A)
d) P(D|A)= P(A|D)P(A) / P(D)
From the information, we get:
P(D|A) = 2% = 0.02P(D|B) = 1% = 0.01P(D|C) = 5% = 0.05The probability that it is a defective tire of brand A = P(A|D). The formula is
P(A|D) = P(A∩D) / P(D)
P(A|D) = P(D|A)P(A) / P(D)
Hence, if we want to know the probability that it is a defective tire, the formula would be P(A|D)= P(D|A)P(A) / P(D).

right, that is the circumference :

if we have only a part of these 360°, then all the attributes of the circle apply only to the corresponding fraction of 360°.
the "segment area" is (I assume) the shaded area.

A 1/6 cup
B 3/4 cup
C 3/8 cup
D 1 1/2 cup
Answer:
3/8 cup

x = 1/4 cup grape juice * 3/2
1/4 * 3/2 = 3/8
is 3(5a + 9) + 5a and 4(5a+6) equivalent
No, 3(5a + 9) + 5a and 4(5a+6) are not equivalent
What are equivalent expressions ?Equivalent expressions are expressions that work the same even though they look different. If two algebraic expressions are equivalent, then the two expressions have the same value when we plug in the same value(s) for the variable(s).
To know if 3(5a + 9) + 5a and 4(5a+6) are equivalent, we simplify both expressions and see if they will have result
simplifying 3(5a + 9) + 5a;
by opening the parentheses
15a+27+5a
collecting like terms
20a+27
simplifying 4(5a+6);
by opening the parentheses,
20a + 24
Therefore 20a + 27 is not thesame as 20a+24. This means 3(5a + 9) + 5a is not equal to 4(5a+6).

Which are two solutions for the given equation 3x 4y 7?
The solutions of the given equation are given below:
(i) 3x+4y =7
(ii) x=6y
(iii) x+πy =4
(iv) x-y =4
All these equations are having infinitely many solution.
Infinitely Many solution:
An equation can have an infinite number of solutions if certain conditions are met. If the lines are coincident and have the same y-intercept, the system of equations has infinitely many solutions. If two lines have the same y-intercept and slope, they are really on the same line.
(i) Given :
3x + 4y = 7 --------------------------- (1)
On putting x = 0 in equation 1
3x + 4y = 7
⇒ 3 × 0 + 4y = 7
⇒ 0 + 4y = 7
⇒ 4y = 7
⇒ y = 7/4
Therefore, ( 0, 7/4) is a solution of given equation.
On putting y = 0 in equation 1
3x + 4 × 0 = 7
⇒ 3x + 0 = 7
⇒ 3x = 7
⇒ x = 7/3
Thus, (7/3, 0) is a solution of given equation.
Hence, 2 out of the infinitely many solutions of the given equation are(0,7/4), (7/3,0).
(ii) x = 6y
Let x = 0
⇒ x = 6y
⇒ 0 = 6y
⇒ y = 0/6
⇒ y = 0
(0,0) is the solution.
Let x = 1
⇒ x = 6y
⇒ 1 = 6y
⇒ y = 1/6
(1,1/6) is the solution.
Hence, 2 out of the infinitely many solutions of the given equation are (0,0), (1,1/6).
(iii) x + πy = 4
let x = 0
⇒ x + πy = 4
⇒ 0 + πy = 4
⇒ πy = 4
⇒ y = 4/π
(0, 4/π) is the solution.
Let y = 0
⇒ x + πy = 4
⇒ x + 0(y) = 4
⇒ x + 0 = 4
⇒ x = 4
(4, 0) is the solution.
Hence, 4 out of the infinitely many solutions of the given equation are (0, 4/π), (4, 0).
(iv) x - y = 4
Let x = 0
⇒ x - y = 4
⇒ 0 - y = 4
⇒ -y = 4
⇒ y = - 4
(0,- 4) is the solution.
Let x = 1
⇒ x - y = 4
⇒ 1 - y = 4
⇒ -y = 4 - 1
⇒ -y = 3
⇒ y = - 3
(1,- 3) is the solution.
Hence, 4 out of the infinitely many solutions of the given equation are(0,- 4), (1,- 3).

1. Find the present value of $5000 to be received in 2 years if the money can be invested at 12%
interest rate compounded continuously.(1 Point)
$6272
O $6365.75
$6356.25
The present value of $5000 to be received in 2 years at a 12% interest rate compounded continuously is $6356.25. This can be calculated by using the formula PV = FV/(1 + r)^t, where PV is the present value, FV is the future value, r is the interest rate, and t is the time period. Therefore, PV = 5000/(1 + 0.12)^2 = $6356.25.
Answer:
C) $6356.25------------------------------
Use the continuous compound equation:
A = Pe^(rt), where A - future value, P - present value, r - annual interest rate, t - number of yearsSubstitute and calculate:
A = 5000*e^(0.12*2) = 6356.25 (rounded)The matching choice is C.
Can someone tell me what number on the number line is greater than -9 for an inequality?
Answer: Any number that is to the right of it, hence greater/bigger.
-8,-7,-6,-5.....
Step-by-step explanation:
Example: If you have -8 vs -9 vs -10 dollars, You have more with -8 vs -9 or -10.
Hence anything to the right of a give number on the number line is greater.
Also, think of the opposite with negatives.
For example with positive numbers, the larger the number the greater, but with negative numbers its the other way around, the smaller the number the greater.
