16 in, 32 in, 64 in3) Evaluate for f(4)
f(x) = (x - 2)3 – 6
Answer: f(x) = 0
Step-by-step explanation:
when f(x) = 4 you plug in 4 wherever you see an x value
so it would be
f(x) = (4 - 2)3 - 6
which gives you a new answer
f(x) = 12 - 6 - 6
f(x) = 0

Step-by-step explanation:
A contractor has submitted bids on three state jobs: an office building, a theater, and a parking garage. State rules do not allow a contractor to be offered more than one of these jobs. If this contractor is awarded any of these jobs, the profits earned from these contracts are: million from the office building, million from the theater, and million from the parking garage. His profit is zero if he gets no contract. The contractor estimates that the probabilities of getting the office building contract, the theater contract, the parking garage contract, or nothing are , , , and , respectively. Let be the random variable that represents the contractor's profits in millions of dollars. Write the probability distribution of . Find the mean and standard deviation of . Round your answers to three decimal places, if required.
Answer:
The following are the answer to this question:
Step-by-step explanation:
In the given question the numeric value is missing which is defined in the attached file please fine it.
Calculating the probability of the distribution for x:
[tex]\to f(x) = 0.19\ for \ x=14\\\\\to f(x) = 0.29 \ for\ x=7\\\\\to f(x) = 0.38\ for \ x=1\\\\\to f(x)=0.14 \ for \ x=0\\[/tex]
The formula for calculating the mean value:
[tex]\bold{ E(X)= x \times f(x)}[/tex]
[tex]=14 \times 0.19+7 \times 0.29+1 \times 0.38+0\times 0.14\\\\=2.66 + 2.03+0.38+ 0\\\\=5.07[/tex]
[tex]\bold{E(X^2) = x^2 \times f(x)}[/tex]
[tex]=14^2 \times 0.19+7^2 \times 0.29+1^2 \times 0.38+0^2 \times 0.14 \\\\=196 \times 0.19+ 49 \times 0.29+1 \times 0.38+0 \times 0.14\\\\= 37.24+ 14.21+ 0.38+0 \\\\=51.83[/tex]
use formula for calculating the Variance:
[tex]\to \bold{\text{Variance}= E(X^2) -[E(X)]^2}[/tex]
[tex]= 51.83 - (5.07)^2\\\\= 51.83 - 25.70\\\\=26.13[/tex]
calculating the value of standard deivation:
Standard Deivation (SD) = [tex]\sqrt{Variance}[/tex]
[tex]= \sqrt{26.13} \\\\=5.111[/tex]

5. Find the value of x and y
the value is find the valu of y and it willl be x
Answer:
(2x +12) + (3x +23) = 180
5x + 35 = 180
5x = 145
x = 29
2(29) + 12
58 + 12
70
180 - 70 = 110
y = 110
or
3(29) + 23
87 + 23
110
corresponding angles are equal
y = 110

Answer:
161 1/3
Step-by-step explanation:
We can use ratios to solve
242 x
--------- = ---------------
60 days 40 days
Using cross products
242* 40 = 60x
9680 = 40x
Divide by 60
9680/40 = 60x/60

Answer:
Step 1: Questioning --- Before going on the Internet, students should structure their questions.
Step 2: Planning --- Students should develop a search strategy with a list of sites to investigate.
Step 3: Gathering --- Students use the Web to collect and gather information.
Step 4: Sorting & Sifting --- Students analyze and categorize the data they gathered on the Web.
Step 5: Synthesizing --- Students integrate the information into the lesson, and draw conclusions.
Step 6: Evaluating --- Students assess the results, and if necessary, begin the process again.

Answer:
40 degrees = x
Step-by-step explanation:
As you can see in the picture, there are two lines that indicate that those two lines are equal. So, this triangle is an isosceles triangle, and the base angles of an isosceles triangle are equal. To identify the base angle, check the angles opposite to the side equal. So, we find that 70 is a base angle, so there are two 70 degrees angles. So,
70 + 70 + x = 180 (The angle sum property of triangles)
=> 140 + x = 180
=> x = 180 - 140
=> x = 40
If this helped, please mark me as the brainliest!
Thank you!
Which of the following statements best describes the value of the expression 18x – 35, when x = 2?
A. The result is not a whole number.
B. The result is a prime number.
C. The result is a composite number.
D. The result is a whole number that is neither prime nor composite.
Answer:
D
Step-by-step explanation:
Let's plug 2 in for x:
18 * 2 - 35 = 36 - 35 = 1
Now, look at the answer choices:
A) Well, 1 is a whole number; it's not a fraction or a decimal. So eliminate A.
B) 1 is not a prime number; the smallest prime number is 2. So eliminate B.
C) 1 is also not a composite number; the smallest composite number is 4. So eliminate C.
D) This is true. 1 is a whole number, but it's not prime or composite, as seen above.
Thus, D is the answer.

O x = 2
O x = 6
O x = 8
O x = 12
Answer:
x=8
Step-by-step explanation:
Solve for x
[tex]\frac{1}{4}x+5=7[/tex]
[tex]\frac{1}{4}x=2[/tex]
[tex]x=8[/tex]
Answer:
8
Step-by-step explanation:
(1/4)*x+5 = 7 // - 7
(1/4)*x-7+5 = 0
1/4*x-2 = 0 // + 2
1/4*x = 2 // : 1/4
x = 2/1/4
x = 8

A company currently has 200 units of a product on hand that it orders every 2 weeks when the salesperson visits the premises. Demand for the product averages 20 units per day with a stand deviation of 5 units. Lead time for the product to arrive is 7 days. Management has a goal of a 95% probability of not seeking out for this product. The salesperson is due to come in late this afternoon when 180 units are left in stock (assuming that 20 are sold today). How many units should be ordered
Answer: 289 units
Step-by-step explanation:
Given the following :
Inventory (I) = 180
Lead time (L) = 7 days
Review time (T) = 2 weeks = 14 days
Demand (D) = 20
Standard deviation (σ) = 5
Zscore for 95% probability = 1.645
Units to be ordered :
D(T + L) + z(σT+L)
(σT+L) = √(T + L)σ²
= √(14 + 7)5²
= √(21)25
= 22.9
D(T + L) + z(σT+L) - I
20(14 + 7) + 1.645(22.9 + 7) - I
= 420 + 49.1855 - 180
= 289.1855
= 289 quantities

You buy one shirt for $22 and two pairs of shorts. Your total cost is $56. Assuming both pairs of shorts cost the same
amount, what is the price of one palr of shorts?
What is the correct equation and solution for this problem?
2 x - $22 = $56, x= $34
2 x + $22 = $56: x= $34
2 x + $22 = $56: x= $17
2 x - $22 = $56: x= $17
let the cost of sorts be x
then 2x + 22 = 56
2x = 56 - 22
x = 34/2
x = 17
So, it is C :)
Answer:
2 x + $22 = $56: x= $17
