What are the solutions of the quadratic equation? 2 x^2 – 16 x + 32 = 0

Answers

Answer 1

Answer:

X=4,4

Step-by-step explanation:

2 x^2 – 16 x + 32 = 0

2(x^2-8x+16)=0

X^2-(4+4)X+16=0

x^2-4x-4x+16=0

x(x-4)-4(x-4)=0

(x-4)(x-4)=0

X=4,4

So the solution is X=4,4

how much ₹ each will get if 242.46₹ is distributed equally among the students​

Answers

Complete Question:

How much ₹ will each get if 242.46₹ is distributed equally among the 6 students​

Answer:

Each of the 6 students will get ₹40.41

Step-by-step explanation:

Given

[tex]Amount = 242.46[/tex]

[tex]Students = 6[/tex]

Required

Determine how much each student gets

To do this, we simply divide the total amount by the number of students

i.e.

[tex]Each\ Students = \frac{Amount}{Number\ Students}[/tex]

[tex]Each\ Students = \frac{242.46}{6}[/tex]

[tex]Each\ Student = 40.41[/tex]

Hence, each of the 6 students will get ₹40.41

A surgical procedure requires choosing among four alternative methodologies. The first can result in five possible outcomes, the second can result in two possible outcomes, and the remaining methodologies can each result in four possible outcomes. What is the total number of outcomes possible?

Answers

Answer:

15 possible outcomes

Step-by-step explanation:

Since each one of these methodologies are not related to one another and they do not need to be chosen in any order or consecutively then the possible outcomes would only need to be added all together to calculate the total possible outcomes. Since each outcome is independent. Therefore,

m1 = 5 outcomes

m2 = 2 outcomes

m3 = 4 outcomes

m4 = 4 outcomes

5 + 2 + 4 + 4 = 15

we can see that there are a total of 15 possible outcomes

Priya and Joe travel the same 16.8 km route. Priya starts at 9.00 am and walks at a constant speed of 6 km/h Joe starts at 9.30 am and runs at a constant speed. Joe overtakes Priya at 10.20 am At what time does Joe finish the route?

Answers

Answer:

12:05 PM

Step-by-step explanation:

Priya started at 9:00 AM.

Speed of Priya = 6 km/hr

Joe started at 9:30 AM.

Time at which Joe overtakes Priya = 10:20 AM

Total time taken by Priya = 1 hour 20 min = [tex]\frac{4}{3}\ hr[/tex]

Total time taken by Joe = 50 min = [tex]\frac{5}{6}\ hr[/tex]

Distance traveled by Priya and Joe is same.

Formula for distance is:

[tex]Distance =Speed\times Time[/tex]

Distance covered by Priya = [tex]6 \times \frac{4}{3}[/tex] km

Let speed of Joe = [tex]S[/tex] km/h

Distance covered by Joe = [tex]S \times \frac{5}{6}[/tex]

[tex]S \times \dfrac{5}{6} = 6 \times \dfrac{4}{3}\\\Rightarrow S =\dfrac{48}{5}\ km/hr[/tex]

Total distance to be covered = 16.8 km

Total time to be taken by Joe =

[tex]\dfrac{16.8}{\frac{48}5} = \dfrac{16.8\times 5}{48} = \dfrac{84}{48} = 1.75\ hours[/tex]

1.75 hours mean 1 hour and 45 minutes.

Finishing time at which Joe finishes = 9:30 AM + 1 hour 45 minutes = 12:05 PM

The cost of medical care abroad is often significantly less than in the United States. In 2014, the cost of knee replacement surgery in the United states was $34,000. This cost was $4000 more than four times the cost of knee replacement surgery in India. Find the cost of Knee replacement surgery in India.

Answers

Answer:

Cost in India: $7500

Step-by-step explanation:

Represent cost in India with I and cost in United States as U.

Given

[tex]U = 3400[/tex]

[tex]U = 4000 + 4 * I[/tex]

Required

Find I

Simply substitute 34000 for U in the second equation

[tex]34000 = 4000 + 4 * I[/tex]

[tex]34000 = 4000 + 4I[/tex]

Solve for 4I

[tex]4I = 34000 - 4000[/tex]

[tex]4I = 30000[/tex]

Solve for I

[tex]I = 30000/4[/tex]

[tex]I = 7500[/tex]

Hence, the cost in India is $7500

a ¿Cuánto deprecia el vehículo cada año?
b. ¿Cuál será su valor al cabo de 5 años?
c. Haz la tabla de depreciación y valor por año​

Answers

Responder:

$ 3,285

$ 7545

Explicación paso a paso:

Dado que:

Costo del vehículo = $ 23,970

Valor de rescate = $ 975

Vida útil = 7 años

Depreciación por año = (costo del vehículo - valor residual) / vida útil

Depreciación por año = (23970 - 975) / 7

Depreciación por año = 22995/7

Depreciación por año = $ 3285

Valor del vehículo después de 5 años:

23970 - (3285 * 5)

= $ 7545

Año _____ valor del vehículo

Alice is saving her chore money in a bank account. She makes a deposit of $13 in the first month.
Then every month, she deposits $25. Alice forms a sequence of her account balance, An where n
refers to the number of months. Which of the statements are correct about this sequence?
Select all that apply.

Answers

Answer:

Option (3) and Option (5)

Step-by-step explanation:

Alice invested $13 in the first month.

Then she deposits $25 every month.

Therefore, sequence formed by the deposit will be an arithmetic sequence.

First term of the sequence will be,

[tex]A_1=13[/tex]

Since, recursive formula formula of a sequence is given by the formula,

[tex]A_n=A_{(n-1)}+d[/tex]

Where 'd' = common difference in each term of the sequence

Recursive formula for the sequence will be,

[tex]A_n=A{(n-1)}+25[/tex]

Since, explicit formula for the arithmetic sequence is represented by the formula,

[tex]A_n=A_1+(n-1)d[/tex]

where n = number of term

d = common difference

Therefore, nth term of the sequence formed will be represented by the explicit formula,

[tex]A_n=13+(n-1)25[/tex]

[tex]A_{10}=13+(10-1)25[/tex]

      = 13 + 225

      = 238

[tex]A_{8}=13+(8-1)25[/tex]

     = 188

[tex]A_{12}=13+(12-1)25[/tex]

      = 288

Therefore, Option (3) and Option (5) will be the answer.

The weekly salaries of teachers in one state are normally distributed with a mean of $490 and a standard deviation of $45. What is the probability that a randomly selected teacher earns more than $460 a week?

Answers

Answer:

0.74751

Step-by-step explanation:

Using the z score formula

z = (x-μ)/σ, where

x is the raw score = $460

μ is the population mean = $490

σ is the population standard deviation = $45

z = 460 - 490/45

z = -0.66667

Probability value from Z-Table:

P(x < 460) = 0.25249

P(x > 460) = 1 - P(x<460)

P(x > 460) = 1 - 0.25249

P(x > 460) = 0.74751

The probability that a randomly selected teacher earns more than $460 a week is 0.74751

if quadrilateral PQRS is an isoceles trapezoid if RP=12 then SQ= ?

Answers

The question is missing parts. Here is the complete question.

Quadrilateral PQRS (shown below) is an isosceles trapezoid. If RP = 12, then SQ = ?

Answer: SQ = 12

Step-by-step explanation: A trapezoid is a quadrilateral with two opposite parallel sides, called bases. The trapezoid is an isosceles trapezoid when the non-parallel sides have the same length.

One property of isosceles trapezoid is that its diagonals are congruent, i.e., have the same length.

In the picture, segment RP is one of the trapezoid's diagonal. It is asking the measure of SQ, which is the other diagonal. So:

SQ = RP

SQ = 12

Segment SQ of isosceles trapezoid PQRS is 12 units.

What is the probability that the sample proportion exceeds 0.84?

Answers

Answer:

0.9495

Step-by-step explanation:

We are given;

Population proportion; p = 90% = 0.9

Sample size; n = 100

Sample Proportion; p^ = 0.84

Formula to find the probability that sample proportion exceeds 0.84 is;

Z = P(p^ > 0.84) = (p - p^)/√(p^(1 - p^)/n)

Z = (0.84 - 0.9)/√(0.84(1 - 0.84)/100)

Z = -0.06/0.03666

Z = -1.64

From online z-score calculator attached, the probability is;

P(x>Z) = 0.9495
