Translate A’B’C by the directed line segment from (0,0) to (-3,-2)

Answer:60 degrees

Step-by-step explanation: The three angles of a triangle add to 180, a right angle is 90 so 180-90-30= 60.

Answer: The correct answer would be n/255 = 115/360 (N= 81.46)

Step-by-step explanation:

n/255 = 115/360

155/360 = (255)

n = 81.46 ft squared

The height of the triangle is h = 18.18 inches

Given data ,

In an equilateral triangle, all three sides are equal in length.

Let the length of each side be s

Now , the perimeter of the equilateral triangle is given as 63 inches, so we have:

Perimeter of the triangle = 3s = 63 inches

Dividing both sides by 3, we get:

s = 63/3 = 21 inches

Let's now plot an altitude from one of the equilateral triangle's vertex to the side's midway. As a result, two right-angled triangles will be formed, each with the hypotenuse "s" and sides "s/2" and "h"

From the Pythagoras theorem , we get

(h²) + ((s/2)^2) = s²

Substituting the values we found earlier for "s", we get:

(h²) + ((21/2)²) = 21²

Simplifying further, we have:

(h²) + (10.5²) = 21²

(h²) + 110.25 = 441

Subtracting 110.25 from both sides, we get:

h² = 330.75

On taking square roots on both sides , we get

h = √(330.75)

h ≈ 18.18 inches

Hence , the height of the equilateral triangle is 18.18 inches

In the above triangle,

1) the sum of side 1 and 2 is: 4x² + 3x + 4
2) the length of side 3 is: 5x³-6x²-12

1) To find the sum of side 1 and side 2, we simply need to add them together.

Side 1 = 3x² - x - 1

Side 2 = x² + 4x +  5

Side  1 + Side 2 = (3x²  - x - 1) + (x²  + 4x +  5)

= 3x² + x² - x + 4x - 1 + 5

= 4x² + 3x + 4

Therefore, the sum of side 1 and side 2 is = 4x² + 3x + 4

2)  We can derive the expression of the thried side by removing the expression in  (1) above form the perimeter.

That is;

(5x³-2x² + 3x - 8) - (4x² + 3x + 4)

First we distribute the negative sign

= 5x³-2x² + 3x - 8 + -1 (4x² + 3x + 4)

= 5x³-2x² + 3x - 8 + -1 (4x²) -1( 3x) -1( 4)

= 5x³-2x² + 3x - 8 + -4x² - 3x - 4

Combining like terms we have

= (5x³) (-2x²+-4x²) + (3x +- 3x) + (-8 +   - 4)

= 5x³-6x²-12

Hence the missing side (thrid side is) 5x³-6x²-12

The weekly benefit of the employees is A = £ 11.40

Given data ,

Let's calculate the weekly benefit for an employee who spends an average of £14 each weekday and £22 on each day of the weekend, considering the 10% discount they receive at Tesco stores.

First, we'll calculate the total amount spent on weekdays and weekends separately:

Amount spent on weekdays = £14/day x 5 days/week = £70/week

Amount spent on weekends = £22/day x 2 days/week = £44/week

Next, we'll calculate the total amount spent in a week by adding the amounts spent on weekdays and weekends:

On simplifying the equation , we get

Total amount spent in a week = £70 + £44 = £114

Now, we'll calculate the 10% discount on the total amount spent:

10% of £114 = £11.40

Hence , the weekly benefit to the employee who receives a 10% discount on their shopping at Tesco stores would be £11.40

Step-by-step explanation:

C. No, because a difference in proportions of 0.4 or more occurred 7 out of 200 times, meaning the difference is not statistically significant and the new additive is not more effective.

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

Explanation:

If the new additive was more effective than the old one, then the difference in proportions (new - old) should be fairly large.

Count the dots over the x axis labels of "0.4" through "0.6"

That makes 5+1+1 = 7 dots total.

There are 7 instances where the difference of proportions is 0.4 or larger.

This is out of 200 observations, so 7/200 = 0.035 = 3.5% of the differences have 0.4 or larger.

This is not very significant. The general rule of thumb is to use 5% as the threshold. Some stats textbooks will use 10%. Other times your teacher will specify the significance level. The Greek letter alpha is often used.

Because 3.5% < 5%, we consider the new additive to not be that effective compared to the original additive.
