Which list shows these numbers in order from least to greatest?
Answer:
D
Step-by-step explanation:
When we simplify the numbers below:
|-5.1| = 5.1
[tex](-2)^{3}[/tex] = -8
[tex]-\sqrt{24}[/tex] = -4.8
[tex]\sqrt{24}[/tex]= 4.8
[tex]-\sqrt{60}[/tex] = -7.7
When we line the decimals from least to greatest we get:
-8, -7.7, -4.8, 4.8, 5.1
Leaving D the correct answer

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.

Amelia needs to buy some dog food. At the nearest store,3 bags of dog food cost $8.25 how much would Amelia spend on 6 bags of dog food?
Answer:
$16.5
Step-by-step explanation:
Let one bag of dog food be x. 3x is equal to 8.25, and we are trying to figure out what 6x is. 6x is double 3x, so we need to double 8.25, which is 16.5.
Answer:
16.5
Step-by-step explanation:
8.25+8.25 =16.25 because 8.25 is 3 bags of food it says.

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.
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:
[tex]x\leq 76[/tex]
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:
[tex]\implies 8(x-4)\leq 576[/tex]
Expand brackets:
[tex]\implies 8x-32\leq 576[/tex]
Add 32 to both sides:
[tex]\implies 8x\leq 608[/tex]
Divide both sides by 8:
[tex]\implies x\leq 76[/tex]
Let the number be x

8
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:
|x| = 8x = 8, x = -8-Chetan K
Solution:
Note that:
Given equation: IxI = 8If a question is saying to find the absolute value of a number, that number will always result in positive.This can lead to two solutions:
IxI = 8 ⇒ x = 8IxI = 8 ⇒ x = -8QUESTION 7 The probability of winning a particular contest is 4%. What is the probability of not winning this contest? Use 2 decimal places in your answer.

What is the area of a triangle with vertices at (−4, −6), (1, −6), and (1, 2)?
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
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)

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.

D
44°
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.
