Ken wants to install a row of ceramic tiles on a wall that is 21 3/8 inches wide. Each tile is 4 1/2 inches wide. What fraction

of a tile must he install at the end of the row to totally fill the space?

Answer: 1/4

Step-by-step explanation:

He needs 4 3/4 whole tiles, you could round it to 5 whole tiles. He needed 4 3/4 whole tiles. To completely fill in all the spaces on the wall evenly, it needs to be 5 even, while, tiles. To fill in the empty space, you must subtract 5 and 4 3/4, which explains why Part A says “How many whole tiles does he need” and the answer “4 3/4” So, Subtraction: 5- 4 3/4 = 1/4!

Your welcome :)

PLZ HELP!!!!!!! A sequence is defined by the recursive function f(n + 1) = f(n) – 2.
tensa zangetsu [6.8K]

Answer:

f(n + 1) = f(n) - 2 \\ n = 1 -  -  -  - f(1 + 1) =f(1) - 2 \:  \:  \:  -  -   - >   \:  \: f(2) = 10 - 2 = 8 \\ f(2) = 8 \\ n = 2 -  -  -  - f(2 + 1) = f(2) - 2 \:  \:  \:  -  -  -  >  \:  \:  \: f(3) = 8 - 2 = 6 \\ so \: f(3) = 6 \\ and \: we \: are \: done.

PLEASE HELP ASAP! Solve the equation. Show all your work. Round your answers to four decimal places. Make sure you solve
Evgesh-ka [11]

Answer:

  x ≈ 1.9087

Step-by-step explanation:

We don't know what methods you learned in class, but here's one way to solve the equation.

Make x the exponent of a constant:

  5^(x+2) = 3^(3x)

  (5^x)(5^2) = (3^3)^x

  25(5^x) = 27^x

Put the powers all on one side of the equation and everything else on the other side.

  25 = (27^x)/(5^x) = (27/5)^x = 5.4^x

Take logarithms.

  log(25) = x·log(5.4)

  x = log(25)/log(5.4)

  x ≈ 1.9087

Ann is growing two different plants for a science project. Plant A grew 4/12 inch the first week and 2/12 inch the second week.
Galina-37 [17]
Start the number line from 0 and put divisions at 1/12. Then mark at 4/12 for plant A and indicate this was its growth in the first week. Then, make another mark up to 6/12 and indicate this was the plant's growth in the second week.
For plant B, make one mark at 7/12 and indicate that this is plant B's growth in the first week.

After two weeks, plant A has a height of 6/12 inches and plant B has a height of 7/12 inches, so B is taller.

This exercise illustrates that poor quality can affect schedules and costs. A manufacturing process has 120 customer orders to f
Aliun [14]

Answer:

a. P(X = 0) = 0.02586

b.  \mathbf{P(X \leq 2 ) =0.2879}

c.  \mathbf{P(X \leq 5 ) =0.8387}

Step-by-step explanation:

From the given information:

a. If the manufacturer stocks 120 components, what is the probability that the 120 orders can be filled without reordering components?

P(X = 0)=(^{120}_{0}) (0.03)^0 (1-0.03)^{n-0}

P(X = 0)=\dfrac{120!}{0!(120-0)!} (0.03)^0 (1-0.03)^{n-0}

P(X = 0) = 1 × 1 ( 0.97)¹²⁰ ⁻ ⁰

P(X = 0) = 0.02586

b. ) If the manufacturer stocks 122 components, what is the probability that the 120 orders can be filled without reordering components?

P(X \leq 2 ) = [ P(X=0) + P(X =1) + P(X = 2) ]

P(X \leq 2 ) = [(^{122}_{0})(0.03)^0 (0.97)^{122-0}+(^{122}_{1})(0.03)^1  (0.97)^{122-1}+(^{122}_{2})(0.03)^2 (0.97)^{122-2}]P(X \leq 2 ) = [\dfrac{122!}{0!(122-0)! } \times 1 \times  (0.97)^{122}+\dfrac{122!}{1!(122-1)! } \times (0.03)  (0.97)^{121}+\dfrac{122!}{2!(122-2)! } \times 9 \times 10^{-4} \times (0.97)^{120}]

P(X \leq 2 ) = [(1 \times  1 \times  0.02433 )+(122 \times (0.03)  \times 0.025083)+(7381 \times 9 \times 10^{-4} \times 0.02586)]

\mathbf{P(X \leq 2 ) =0.2879}

(c) If the manufacturer stocks 125 components, what is the probability that the 120 orders can be filled without reordering components?

P(X \leq 5 ) = [ P(X=0) + P(X =1) + P(X = 2)  +P(X = 3)+P(X = 4)+ P(X = 5)    ]

P(X \leq 5 ) = [(^{122}_{0})(0.03)^0 (0.97)^{122-0}+(^{122}_{1})(0.03)^1  (0.97)^{122-1}+(^{122}_{2})(0.03)^2 (0.97)^{122-2} + (^{122}_{3})(0.03)^3 (0.97)^{122-3} + (^{122}_{4})(0.03)^4 (0.97)^{122-4}+ (^{122}_{5})(0.03)^5 (0.97)^{122-5}]P(X \leq 5 ) = [\dfrac{122!}{0!(122-0)! } \times 1 \times  (0.97)^{122}+\dfrac{122!}{1!(122-1)! } \times (0.03)  (0.97)^{121}+\dfrac{122!}{2!(122-2)! } \times 9 \times 10^{-4} \times (0.97)^{120} + \dfrac{122!}{3!(122-3)! }*(0.03)^3(0.97)^{122-3)}+ \dfrac{122!}{4!(122-4)! }*(0.03)^4(0.97)^{122-4)} +\dfrac{122!}{5!(122-5)! } *(0.03)^5(0.97)^{122-5)}]

\mathbf{P(X \leq 5 ) =0.8387}

Does anyone know this?
Ksju [112]

Answer:

x = 8

Step-by-step explanation:

4x = 5x - 8         Set both sides equal because they are on a parallelogram

-5x  -5x              Subtract 5x from both sides

-x = -8                Divide both sides by -1

x = 8
