Which problem can be solved using the equation 9x + 14 = 100

The another way is same as;

Multiplying by 0.5 with original price.

Here,

A shop owner increases some prices by 50%.

We have to find another method to find same condition.

What is the percentage?

A relative value indicating hundredth parts of any quantity is called the percentage.

Now,

A shop owner increases some prices by 50%.

Let the original price is x.

Then, The increase value = x * 50% = x * 50/100 = 0.5x

Hence, To find the increase value we have to multiply by 0.5 with original price.

Answer:

104

Explanation:

1. Split the figure by the line the larger portion creates.

2. Calculate the area of the left-hand side... 7 · 8 = 56cm squared.

3. You know that the total length of the figure is 15cm. You've already "used" 7cm of that. So... 15 - 7 = 8.

4. Now, we simply do 6 · 8 = 48. Almost there!

5. Finally, add the values of the left side and the right side (48 + 56 = 104)

6. YOUR ANSWER IS 104 cm squared.

Answer:

  x = 10

Step-by-step explanation:

You can compare parts of each expression to see that x in the left-side expression is replaced by 10 in the right-side expression.

  x = 10

__

If you'd rather, you can work your way down to the same conclusion by undoing the operations that have been done to x.

  (6x -1)° = (6(10) -1)° . . . . . . given

  6x -1 = 6(10) -1 . . . . . . . . . divide both sides by °

  6x = 6(10) . . . . . . . . . . . .  add 1 to both sides

  x = 10 . . . . . . . . . . . . . . . . divide both sides by 6

Answer:

3rd answer choice

Step-by-step explanation:

Any time you have a proportion, the two ratios have to match, so 32 and x+8 are the bases, so you need to length of the side of those bases, 20 is the length of the base for the 32, but notice how 5 is not the side for x+8, therefore, 20-5 = 15, so 15 is the side adjacent to the base x+8, and they are in the right order small side / big side = small base / big base

Answer: Average of other 4 numbers =5

Step-by-step explanation:

Sum of n numbers = Average of n numbers x n

Given: Average of 6 numbers =4

so sum of 6 numbers  = 6x 4 = 24

Average of 2 numbers = 2

Sum of 2 numbers = 2 x 2 =4

Sum of rest of 4 numbers = sum of 6 numbers  - Sum of 2 numbers

= 24-4

=20

Average of 4 numbers = [tex]\dfrac{20}{4}[/tex]

Answer:  Choice B

There is not convincing evidence because the interval contains 0.

========================================================

Explanation:

The confidence interval is (-0.29, 0.09)

This is the same as writing -0.29 < p1-p1 < 0.09

The thing we're trying to estimate (p1-p2) is between -0.29 and 0.09

Because 0 is in this interval, it is possible that p1-p1 = 0 which leads to p1 = p2.

Therefore, it is possible that the population proportions are the same.

The question asks " is there convincing evidence of a difference in the true proportions", so the answer to this is "no, there isn't convincing evidence". We would need both endpoints of the confidence interval to either be positive together, or be negative together, for us to have convincing evidence that the population proportions are different.

There is not convincing evidence because the interval contains 0.

The mean of your estimate plus and minus the range of that estimate constitutes a confidence interval. Within a specific level of confidence, this is the range of values you anticipate your estimate to fall within if you repeat the test. In statistics, confidence is another word for probability.

We have, the confidence interval as (-0.29, 0.09)

and, the same as writing -0.29 < p1-p1 < 0.09

Now, as the interval is 0 then

p1 - p2 = 0

p1 = p2

There is a chance that the population ratios are identical.

So, there isn't convincing evidence.

For us to have strong evidence that the population proportions are different, the ends of the confidence interval must be either positive together or negative together.

Answer:

B

Step-by-step explanation:

There is a common difference d between consecutive terms, that is

d = 17 - 22 = 12 - 17 = 7 - 12 = 2 - 7 = - 5

This indicates the sequence is arithmetic with n th term

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 22 and d = - 5, then

[tex]a_{n}[/tex] = 22 - 5(n - 1) = 22 - 5n + 5 = 27 - 5n → B

Answer:

The quadratic equations and their solutions are;

9 ± √33 /4 = 2x² - 9x + 6.

4 ± √6 /2 = 2x² - 8x + 5.

9 ± √89 /4 = 2x² - 9x - 1.

4 ± √22 /2 = 2x² - 8x - 3.

Explanation:

Any quadratic equation of the form, ax² + bx + c = 0 can be solved using the formula x = -b ± √b² - 4ac / 2a. Here a, b, and c are the coefficients of the x², x, and the numeric term respectively.

We have to solve all of the five equations to be able to match the equations with their solutions.

2x² - 8x + 5, here a = 2, b = -8, c = 5.                                                  x = -b ± √b² - 4ac / 2a = -(-8) ± √(-8)² - 4(2)(5) / 2(2) = 8 ± √64 - 40/4.     24 can also be written as 4 × 6 and √4 = 2. So                                                                                     x = 8 ± 2√6 / 2×2= 4±√6/2.

2x² - 10x + 3, here a = 2, b = -10, c = 3.                                                   x =-b ± √b² - 4ac / 2a =-(-10) ± √(-10)² - 4(2)(3) / 2(4) = 10 ± √100 + 24/4. 124 can also be written as 4 × 31 and √4 = 2. So                                                                              x = 10 ± 2√31 / 2×2 = 5 ± √31 /2.

2x² - 8x - 3, here a = 2, b = -8, c = -3.                                                    x = -b ± √b² - 4ac / 2a = -(-8) ± √(-8)² - 4(2)(-3) / 2(2) = 8 ± √64 + 24/4.     88 can also be written as 4 × 22 and √4 = 2. So                                                                             x = 8 ± 2√22 / 2×2 = 4± √22/2.

2x² - 9x - 1, here a = 2, b = -9, c = -1.                                                     x = -b ± √b² - 4ac / 2a = -(-9) ± √(-9)² - 4(2)(-1) / 2(2) = 9 ± √81 + 8/4.                                          x = 9 ± √89 / 4.

2x² - 9x + 6, here a = 2, b = -9, c = 6.                                                    x = -b ± √b² - 4ac / 2a = -(-9) ± √(-9)² - 4(2)(6) / 2(2) = 9 ± √81 - 48/4.                                                                             x = 9 ± √33 / 4 .

Answer: 11/2

Step-by-step explanation:

to rewrite as mixed number you multiply the whole number by the denominator and add that to the numerator and get 55/10, then simplify it to 11/2 easy. also for decimal its jus 5.5

The other form to write 2 5/10 is 52/10.

The fractional bar is a horizontal bar that divides the numerator and denominator of every fraction into these two halves.

We have mixed fraction as 2 5/10.

Now, to write the mixed fraction into normal we must follow:

Numerator = Divisor x Quotient+ Remainder

Here, Divisor= 10, Quotient = 2 and Remainder= 5

So, the Normal Fraction is

= ( 10 x 5 +2)/ 10

= 52/10
