Answer:
12 wins and 9 losses.
Step-by-step explanation:
Because they are winning 57.14% of there games so if 8 out of 14=57.14% then that means if they would have still one at the exact pace then.
12 wins out of 21 would mean they would have one 57.14% of there games.

D

Give your answer to 1 decimal place.
Answer: 45.1
Step-by-step explanation:
The area of the figure is about 45 square cm.
What is a triangle?A triangle is a polygon with 3 sides.
Given the quadrilateral ABCD.
The sum of the interior angles of a triangle is 180°, therefore,
44° + 38° + m∠C = 180°
m∠C = 180° - 44° - 38°
m∠C = 98°
Now, using the sine law in triangle BDC, it follows:
sin44°/ BC = sin98°/10
BC = (10·sin44°)/ sin98°
BC ≈ 7
The area of a triangle is half the product of its two sides and the sine of the included angle, therefore, the area of triangle BDC is:
A₁ = (1/2)× 10×7× sin38°
A₁ = 21.5
Now, in triangle ABD,
cos55° = AD/10
AD = 10 cos55°
Similarly,
sin55° = AB/10
AB = 10sin 55°
Hence, the area of the triangle ABD is:
A₂ = (1/2) × (10 cos55°) ×(10sin 55°)
A₂ = 23.5
Therefore, the total area of the figure is:
A = A₁ + A₂
A = 21.5 + 23.5
A = 45.0
Hence, the area of the figure is about 45 square cm.

4. Cindy is designing a rectangular fountain in the middle of a courtyard. The rest of the courtyard will be covered in stone. The part of the courtyard that will be covered in stone has an area of 246 square feet. Show your work. b. What fraction of the courtyard will be occupied by the fountain?
Answer:
12 x 22 = 264 so that would be 264 - 246 = 18
The answer is 18 square feet.
Step-by-step explanation:
You'll need to simplify 18/264, then divide that number into 18/264 such as 18/264 divided by 2/2 or 3/3.

The product of 8/9 and the sum of a number and – 4 is less than or equal to 64.
What are all the possible values of the number? Show your work.
Answer:

Step-by-step explanation:
Let x = unknown number
[tex]\implies \dfrac89 \times (x-4)\leq 64[/tex]
[tex]\implies \dfrac{8(x-4)}{9}\leq 64[/tex]
Multiply both sides by 9:

A bank's loan officer rates applicants for credit. The ratings are normally distributed with a mean of 200 and a standard deviation of 50. Find [tex]P_{60}[/tex] , the score which separates the lower 60% from the top 40%.
Please explain!
Answer:
a = 200 + 0.253 * 50 = 212.65
So the value of height that separates the bottom 60% of data from the top 40% is 212.65. And rounded would be 212.
Step-by-Step Explanation:
The normal distribution is a "probability distribution that is symmetric around the mean, demonstrating that data near the mean occur more frequently than data distant from the mean."
The Z-score is defined as "a numerical measurement used in statistics of a value's relationship to the mean (average) of a set of values, expressed in standard deviations from the mean."
Let X be the random variable that represents how a loan officer scores credit applications from a population, and we know that the distribution for X is provided by:
X ~ N (200,50)
Where u = 200 and o = 50
And the best way to solve this problem is using the normal standard distribution and the z score given by:
Z = x - u/o
For this part we want to find a value a, such that we satisfy this condition:
P (X > a) = 0.40 (a)
P (X<a) = 0.60 (b)
In this example, both conditions are equal.
The z value that meets the criterion with 0.60 of the area on the left and 0.40 of the area on the right is z=0.253, as shown in the attached figure. P(Z0.253)=0.60 and P(z>0.253)=0.4 in this scenario.
Using the prior condition (b), we get:
P (X < a) = P (X-u/a < a - u/o) = 0.6
P (Z < a-u/o) = 0.6
But we know which value of z satisfy the previous equation so then we can do this:
z = 0.253 < a -200/50
And if we solve for a we got
a = 200 + 0.253 * 50 = 212.65
So the value of height that separates the bottom 60% of data from the top 40% is 212.65. And rounded would be 212.7.
Enter your answer and show all the steps that you use to solve this problem and write your final answer in factored form.
Simplify: (9x^3 + 2x^2 - 5x + 4) - (5x^3 - 7x + 4)
Answer:
4x³ +2x² + 2x
Step-by-step explanation:
1- Determine the sign
2- Combine like terms
The identity function on A, idA: A →A is defined by idA(a) = a.
1. (a) We defined a function as a relation with a particular property, thus
we can talk about properties of relations. Prove that if f : A →A
is reflexive, then f =idA.
(b) Prove that if f is symmetric then the function f^2 : A →A defined
by f^2(a) = f (f (a)) is the identity.
(c) Prove that if f is transitive then the function g : im(f) →im(f) given
by g(f (a)) = f (f (a)) is the identity on im(f) .
These are just sketches, you should polish them yourself. In analogy to relations, I will write aFb to mean the statement f(a) = b.
(a) aFa, so f(a) = a. This is the definition of the identity function.
(b) aFb => bFa, so f(a) = b and f(b) = a. Therefore f(f(a)) = a by substitution, and hence f^2 is the identity function.
(c) aFb and bFc => aFc. So f(f(a)) = c, and f(a) = c. Thus f(c) = c, which is the identity. Make sure you sort out the im(F) stuff when you clean this up.

Given the triangle ABC with points:
A - (1, 3)
B - (-2, 2)
C - (4, 0)
Rotate ABC 180 degrees clockwise about the origin and then translate the resulting triangle five units down. Determine the ordered pairs for A', B', and C'.
Rotating and translating the triangle are illustrations of transformations
The ordered pairs for A', B' and C' are (-1, -8), (2, -7) and (-4, -5)
How to transform the triangleThe coordinates of the pre-image of the triangle are:
A = (1, 3)
B = (-2, 2)
C = (4, 0)
When the triangle is rotated 180 degrees, the rule of transformation is:
(x,y)→(−x,−y)
So, we have:
A' = (-1, -3)
B' = (2, -2)
C' = (-4, 0)
When the triangle is translated 5 units down, the rule is:
(x,y)→(x,y-5)
So, we have:
A' = (-1, -8)
B' = (2, -7)
C' = (-4, -5)
Hence, the ordered pairs for A', B' and C' are (-1, -8), (2, -7) and (-4, -5)

Answer:
x = -8, x = 8
Step-by-step explanation:
|x| = 8
The absolute value turns the negative value inside the positive.
When given an absolute value like this, there are two cases.
If the absolute value is equal to something greater than 0, it has two solutions. If less than 0, it has no solutions. If it is equal to 0 it has 1 solution.
Since 8 is greater than 0, there are two solutions.
On solution is the positive version, one is the negative
So:

Answer:
20
Step-by-step explanation:
firstly let's find out the side lengths of the triangle using formula
[tex]length \: = \: \sqrt{(y₂-y1) + ( y₂-y1)}[/tex]
length of AB
[tex] \sqrt{( - 6 - 2) {}^{2} + ( - 4 - 1) {}^{2} } = \sqrt{89} [/tex]
length of AC
[tex] \sqrt{( - 6 - 2) {}^{2} + (1 - 1) {}^{2} } = 8[/tex]
length of BC
[tex] \sqrt{( - 6 - ( - 6)) {}^{2} + (1 - ( - 4)) {}^{2} } = 5[/tex]
Now we have all three side lengths:
a =√89 b = 8 and c = 5
using this formula to find the semi perimeter where a, b and c are the side lengths, input them in
[tex]s \: = \: \frac{a + b + c}{2} [/tex]
[tex]s = \frac{ \sqrt{89} + 8 + 5 }{2} = \frac{13 + \sqrt{89} } {2} [/tex]
Use heron's formula
[tex]area = \sqrt{s(s - a)(s - b)(s - c)} [/tex]
[tex]area = \sqrt{ \frac{13 + \sqrt{89} }{2}(\frac{13 + \sqrt{89} }{2} - \sqrt{89})( \frac{13 + \sqrt{89} }{2} - 8)(\frac{13 + \sqrt{89} }{2} - 5 } = 20[/tex]
area = 20
If a coin is tossed 4 times, and then a standard six-sided die is rolled 4 times, and finally a group of three cards are drawn from a standard deck of 52 cards without replacement, how many different outcomes are possible?
Answer:
89,820,057,600.
Step-by-step explanation:
For the number of ways 5 cards can be taken from a standard 52 card deck, there are 52 choices for the first card. After the first card is chosen, there are 51 choices remaining for the second card. Following this pattern, you will the total number of ways the 5 cards can be chosen being 52 x 51 x 50 x 49 x 48 = 311,875,200. Or, you can also use the permutation of 52 cards taken 5 at a time which is 52!/(52 – 5)! = 311,875,200.
Hence, the total number of outcomes for all the above is 8 x 36 x 311,875,200 = 89,820,057,600.
