Scientists conducting a study on global climate change want to determine if there has been an increase in the number of days per year that the temperature in El Paso rises above 100 degrees. In 1981, there were 21 days (5.75%) where the temperature was in the triple digits. The scientists want to know whether this percentage has increased. Which pairs of hypotheses is the most appropriate for addressing this question?

Answer:

what is the question?

Step-by-step explanation:

Answer:

Below.

Step-by-step explanation:

Total scores = 6*90 = 540.

He had more than one 89 ( mode) and max score - min score = 18.

Let max score = x then min = x-18.

Lets say he has 3 89's then

x +  x - 18 + 3*89 + y  = 540  where y is another score then:

2x + 249 + y = 540

2x + y =  291

x = 98 and y = 95 will fit this so the 6 scores could be

80, 89, 89, 89, 95, 98.

Answer:A

Step-by-step explanation:

Answer:

9). x = 36.9°

10). x = 18.3°

Step-by-step explanation:

9). By applying tangent rule in the given triangle,

   tan(x) = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]

   tan(x) = [tex]\frac{9}{12}[/tex]

   x = [tex]\text{tan}^{-1}(\frac{3}{4})[/tex]

   x = 36.87°

   x = 36.9°

10). By applying sine rule in the given triangle,

   sin(x) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]

   sin(x) = [tex]\frac{11}{35}[/tex]

   x = [tex]\text{sin}^{-1}(\frac{11}{35})[/tex]

   x = 18.32

   x ≈ 18.3°

Answer:

1 stack of 36

Step-by-step explanation:

First find how much one carton can hold

length is 45

width is 20

height is 40

40 * 20 * 45 = 36,000

Then find how much volume each box has

length is 20

width is 10

height is 5

5 * 10 * 20 = 1000

so each box is 1000 volume

1 stack of 36 is good

Answer:

B. 3(2x+1)(x-2)

Step-by-step explanation:

For this case we have the following trinomial:-

6x^2-9x-6

Rewriting we have:-

3(2x^2-3x-2)

Factoring we have:-

3(2x+1)(x-2)

Answer:

80%

Step-by-step explanation:

Because the answer is 80%

Answer:40 percent

Step-by-step explanation:Total number of fruit in a bowl is 15 pieces.

Number of apples are 6 pieces in a bowl.

6/15 times 100 equals 40%

Answer:

2x+y=-7

Step-by-step explanation:

y-y1=m(x-x1)

y-(-5)=-2(x-(-1))

y+5=-2(x+1)

y=-2x-2-5

y=-2x-7

-2x-y=7

2x+y=-7

The key features of the quadratic function are

From the question, we have the following parameters that can be used in our computation:

y = -x² + 4x - 3

A quadratic function is represented as

y = ax² + bx + c

By comapring the equations, we have

a = -1, b = 4 and c = -3

For the key features

Axis of symmetry: x  = -b/2a

So, we have

x  = -4/(2 * -1)

x  = 2

The domain of the function is the set of all real values

For the vertex, we have

(h, k) = (symmetry, f(symmetry))

So, we have

y = -2² + 4(2) - 3

y = 1

So, the vertex is (2, 1)

Answer:

  (b) ... confirm ∠C≅∠E

Step-by-step explanation:

The first step is to read and understand the problem statement. It is asking for a way to prove ΔABC ~ ΔADE  by AA similarity. That means you want to show any two of the three ...

For this purpose, lengths of line segments are irrelevant (eliminating the last two answer choices). The fact that ∠A≅∠A is given, so you only need to find an answer choice that will show one of the last two angle congruences.

Obviously, showing ∠B≅∠E (choice A) is not relevant to the problem.

The only answer choice that is relevant to the question is the second one, showing ∠C≅∠E.

Answer:

22/29

Step-by-step explanation:

Add up all the eight grade student that participated in this survey which is 29.

Then add all the eight grade students that do not play guitar which is 22. So 22/29 is the amount of students that play an instrument other than a guitar in fraction form.

Hopefully you got the correct answer. Let me know if you got it wrong.

Answer:

The better buy is to buy 10 kilograms of potatoes at $ 3.92, since each kilogram costs $ 0.392.

Step-by-step explanation:

To find the cost per unit in each case and then state which is the better buy, the following calculations must be performed:

6kg of potatoes for $ 2.45:

2.45 / 6 = 0.408

15 kg of potatoes for $ 5.9:

5.90 / 15 = 0.393

10 kg of potatoes for $ 3.92:

3.92 / 10 = 0.392

Thus, the better buy is to buy 10 kilograms of potatoes at $ 3.92, since each kilogram costs $ 0.392.

Answer:

$98.4.

Step-by-step explanation:

Since the university has decided that for the following year lecture costs will increase by 20%, workshop costs by 10%, and examination costs will stay the same, and that for level 2 the current hourly costs are 10, 24, and 60 respectively To determine how much the level 2 course cost in the following year, the following calculation must be performed:

10 x 1.2 + 24 x 1.1 + 60 = X

12 + 26.4 + 60 = X

98.4 = X

Thus, the level 2 course will cost $ 98.4 next year.
