So, say the original price is "x" pounds, namely the 100%, then it gets increased by 12% and lands on £190.40, so <span>£190.40 is really 100% + 12% or the 112% then.

since we know that </span><span>£190.40 is 112%, what is "x"?

</span>\bf \begin{array}{ccll}&#10;amount&\%\\&#10;\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\&#10;190.40&112\\&#10;x&100&#10;\end{array}\implies \cfrac{190.40}{x}=\cfrac{112}{100}\implies \cfrac{190.40\cdot 100}{112}=x<span>
</span>

Identify the domain and range of the function f(x) = 2x2 − 6x − 9.
mash [69]
Range is the y values or ouputs
domain is inputs or x vvalues

we can use any x value
but at a certain y value, w can't go below that
find thatminimum
find the vertex
for
ax^2+bx+c
the x value of the vertex is
-b/2a
plug that in to the equaiton to get the y value

-b/2a=-(-6)/(2*2)=6/4=3/2

plug that in
2(3/2)^2-6(3/2)-9
2(9/4)-9-9
9/2-18

-13.5

domain=all real numbers
range=from -13.5 to positive infinity

Exactly 32% of the students in a school play a sport. Fifty students are randomly selected to determine the probability that, at
faltersainse [42]

A binomial probability density function should be used to represent the probability

<h3>How to determine the type of probability density?</h3>

The given parameters are:

  • Proportion that plays sport, p = 32%
  • Number of students selected, p = 50
  • The probability, P = (x ≤ 15)

The proportion that plays sport indicates that

68% of the students do not play sport

So, we have two events, which are

  • Play sport
  • Do not play sport

When there are two possible events, then the binomial probability density function should be used

Complete the proof proving YUZ~VWZ
iVinArrow [24]

Answer:

1. ΔXYZ is a right Δ with altitude YU.

Given

2. ΔXYZ ~ ΔYUZ

Right Triangle Altitude Similarity Theorem

3. VW || XY

Given

4. ∠VWZ ≅ ∠XYZ

Corresponding angles

5. ∠Z ≅ ∠Z

Reflexive property of congruence

6. ΔXYZ ~ ΔVWZ

AA Similarity postulate

7. ΔYUZ ~ ΔVWZ

Transitive property of similar triangles

Step-by-step explanation:

The first statement is given in the problem.  Since we know the altitude of a right triangle, we can use the Right Triangle Altitude Similarity Theorem to say that the triangles formed by the altitude are similar to each other and the original triangle.

Next, we are given in the problem statement that the lines VW and XY are parallel.  Therefore, ∠VWZ and ∠XYZ are corresponding angles, which makes them congruent.  And since ∠Z is equal to itself (by reflexive property), we can use AA similarity to say ΔXYZ and ΔVWZ are similar.

Finally, combining statements 2 and 6, we can use transitive property to say that ΔYUZ and ΔVWZ are similar.

Find the percent of each type of sandwich sold.
elena55 [62]

Answer: 50% of the sandwiches were turkey, 30% were veggie and 20% were tuna.

Step-by-step explanation: The total number of sandwiches sold was 50 in all.

The sales according to type of sandwich were as follows;

25 Turkey

15 Veggie

10 Tuna

50 Total

Since there were 50 sandwiches sold and of these 25 were turkey sandwiches and another 15 were veggie sandwiches, then the remaining which is tuna sandwich is derived as 50 - [25 + 15] which equals 10.

To calculate the percentage per type of sandwich sold;

(a) Turkey is derived as

Percentage turkey = (25/50) x 100

Percentage turkey = 1/2 x 100

Percentage turkey = 50%

(b) Veggie is derived as

Percentage Veggie = (15/50) x 100

Percentage Veggie =  (3/10) x 100

Percentage Veggie = 30%

(c) Percentage tuna = (10/50) x 100

Percentage tuna = 1/5 x 100

Percentage tuna = 20%
