Aanya bought 2 1/2 yards of ribbon. She cuts the ribbon into pieces 3/8 of a yard in length. How many pieces does she have?​

Answer:

[tex]\large\boxed{\red{\sf x =6+\sqrt{53},6-\sqrt{53}} }[/tex]

Step-by-step explanation:

We would like to solve the given quadratic equation by completing the square method .The given equation is ;

[tex]\longrightarrow x^2=12x +17[/tex]

Subtract 12x to both sides ,

[tex]\longrightarrow x^2-12x = 17 [/tex]

Here the co-efficient of x² is already 1 . So , we shall rewrite it as ,

[tex]\longrightarrow x^2-2(6)(x) = 17 [/tex]

Add 6² on both sides ,

[tex]\longrightarrow x^2-2(6)(x) + 6^2=17+6^2 [/tex]

Now LHS is in the form of (a-b)² = a²-2ab+b² ; so that ;

[tex]\longrightarrow (x -6)^2 = 17+36 [/tex]

Simplify RHS ,

[tex]\longrightarrow (x-6)^2=53 [/tex]

Put square root on both sides,

[tex]\longrightarrow (x-6) = \pm\sqrt{53}[/tex]

Add 6 on both sides,

[tex]\longrightarrow x = 6\pm\sqrt{53} [/tex]

Separate the two solutions ,

[tex]\longrightarrow \underline{\underline{x =6+\sqrt{53},6-\sqrt{53}}} [/tex]

And we are done!

Answer:

3 mi

Step-by-step explanation:

Use the equation for area of a triangle, A = 1/2 * base * height. Plug in the numbers you have and solve for the height, You get that 3 = 1/2 * 2 * h, and that h = 3.

Answer:

Average speed was 60mph so 240 ÷ 4 = 60

Answer:

x = 11, 3

Step-by-step explanation:

√(10x - 29) = x - 2

(√(10x - 29))² = (x - 2)²

10x - 29 = x² - 4x + 4

-10x + 29      -10x + 29

x² - 14x + 33  

(x - 11) (x - 3)

x - 11 = 0;     x - 3 = 0

   + 11  +11       +3   +3

x = 11              x = 3

Answer: A: 3/5

Step-by-step explanation:

He made 9 shots

He attempted 15

The ratio will be 9/15, which can be simplified to 3/5

Have a nice day :)

Answer:

A) 3/5

Step-by-step explanation:

No.of baskets attempted = 15

No.of baskets made = 9

Given, To find the ratio of no.of baskets made to no.of baskets attempted

9:15 (or) 9/15

If we simplify 9/15, we get 3/5

Slope = change in Y / change in x

slope = (1-5) /(3-2)

Slope = -4/1

Slope = -4

Answer:

slope = -4

Step-by-step explanation:

The formula for finding slope is (y2 - y1)/(x2 - x1)

x1 = 2

y1 = 5

x2 = 3

y2 = 1

Plugging in our numbers,

(1 - 5)/(3 - 2) = -4/1

= -4

Answer:The temperature at 4 AM is 41 degrees.

Step-by-step explanation:

We have an average temperature of 45 degrees and a high of 53 degrees. That makes the midline 45 and the amplitude 8.

We could spend some time trying to figure out how to get a graph in which x=0 corresponds to midnight. However; that is not necessary. We can use any sinusoidal function we want, as long as we understand which part of the graph corresponds to what hour of the day.

So with midline 45 and amplitude 8, let's choose a simple function:

f%28x%29+=+45%2B8sin%28x%29

The time at which we are to find the temperature, 8 AM, is 8 hours before 4 PM, which is the time when the temperature is maximum. 8 hours is 1/3 of a day, so we want to find the temperature 1/3 of a cycle before 4 PM.

Since we are using a sine function with no horizontal shift, the time of maximum temperature, 4 PM, corresponds to 1/4 of the way through a cycle, at pi/2.

We want to go back 1/3 of a cycle, or (2/3)pi, from pi/2; that puts us at -pi/6.

That makes it easy to find the temperature at 4 AM without a calculator:

45%2B8%2Asin%28-pi%2F6%29+=+45%2B8%28-.5%29+=+45-4+=+41

The temperature at 4 AM is 41 degrees.

Answer:

probably he temperature at 4 AM is 41 degrees.

Answer:

[tex] \frac{3}{23} [/tex]

Step-by-step explanation:

Since we start with 24 marbles, 9 of which are red, the probability of selecting a red marble is 9/24. The red marble is not put back, so there are now 23 marbles, 8 of which are red. It follows that the probability of selecting a second red marble is 8/23. So the probability of selecting a red marble and then another red marble is

[tex] \frac{9}{24} \times \frac{8}{23} = \frac{3}{8} \times \frac{8}{23} = \frac{3}{23} [/tex]

Answer:

'b' and 'c' = 119 degrees

Step-by-step explanation:

Given that this is a basic intersection of straight lines, we can assume 'b' and 'c' are equal as well as the given angle and it's opposite. Given 61 degrees and and two straight lines we can just take 180 degrees - 61 degrees and we get 119 degrees, I solved for 'b', but this will give the same answer for 'c', as 'b' and 'c' are equal.

B = 119°

C = 119°

Step-by-step explanation:

Given the data:

426 429 418 417 422 435 420 410 432 435 423 426 409 437 436 429 411 426 411 438 422 428 413 414

A) Point estimate of the mean(m) : (ΣX) /n

Sample size(n) = 24

(426+429+418+417+422+435+420+410+432+435+423+426+409+437+436+429+411+426+411+438+422+428+413+414) / 24

= 10167 / 24

= 423.625 (3 decimal places)

b) Calculate a point estimate of the standard deviation of oxide thickness for all wafers in the population

s = √[Σ(X - m)² / (n - 1)]

Using calculator :

s = 9.277

s = 9.28 ( 2 decimal places)

C.)

Standard Error of point estimate :

SE = s/√n

SE = 9.28 / √24

SE = 1.8942720

(d) Calculate a point estimate of the median oxide thickness for all wafers in the population.

Median = 0.5 (n +1)th term

0.5(25) = 12.5th term ;

(12th + 13 th term)/2

(423 + 426) / 2

= 849/2

= 424.5

(e) Calculate a point estimate of the proportion of wafers in the population that have oxide thickness greater than 430 angstrom

Number of oxide thickness greater than 430 = 6

(number greater than 430 / total number of oxides)

= 6 / 24

= 1/4

= 0.25
