Answer:

Option 3

Step-by-step explanation:

I know you said no explanation is needed but I'm going to give it anyways

(1)     Semester 1 and 2 have the same interquartile range (12) so it can't be option 1.

(2)    Semester 1 and 2 have the same median so it can't be option 2.

(3)    Option 3 is true, semester 2 does have the greater mean.

(4)    Semester 1 have the greater third quartile so option 4 can't be true.

Answer:

d is the correct answer

The angles for which the ratios shown in the table are 55° and 35°.

Right angled triangle are those triangle for which one of the angle is 90 degrees.

For any angle, X, in a right triangle, trigonometric ratios are defined as,

sin X = opposite side / hypotenuse

cos X = adjacent side / hypotenuse

tan X = opposite side / adjacent side

Given is a table which represents the sine, cosine and tangent of two angles in a right angled triangle.

Let x and y be the two angles.

sin x = 0.819, cos x = 0.573 and tan x = 1.428

x = sin⁻¹ (0.819) = cos⁻¹ (0.573) = tan⁻¹ (1.428) = 54.98° ≈ 55°

The sum of the interior angles of a triangle is 180°.

In a right triangle, one angle is already 90°.

Sum of the other two angles = 180° - 90° = 90°.

One angle is got to be 55°.

Then the other angle will be 90° - 55° = 35°.

The sine of 55° is equal to the cosine of 35° and the sine of 35° is equal to the cosine of 55°.

This is because that the opposite side of one angle will be the adjacent side of the other angle.

And the hypotenuse is constant.

sin 55=opposite side/hypotenuse and cos 35=adjacent side/ hypotenuse

Opposite side of 55° and adjacent side of 35° are same.

So they have the same values.

Hence the measures of the angles are 55° and 35°.

Step-by-step explanation:

Answer:

x = 4

Step-by-step explanation:

Here, given that the two triangles are similar, we want to find the value of x

Mathematically, when two triangles are similar, the ratio of their corresponding sides are equal

Thus, we have it that;

ED/EF = XY/YZ

5/2x-1 = 10/14

14(5) = 10(2x-1)

70 = 20x -10

70 + 10 = 20x

20x = 80

x = 80/20

x = 4

Answer:

21 / 252

Step-by-step explanation:

Recall : nCr = n! ÷ (n-r)!r!

The total possible outcome ; 5 questions out of 10

10C5 = 10! ÷ 5!5! = (10*9*8*7*6)÷(5*4*3*2*1) = 252

Required outcome :

All 5 questions set being from the 7 questions covered and 0 from the 3 left uncovered

7C5 * 3C0

7C5 = 7! ÷ 2!5! = (7*6) ÷ (2*1) = 21

3C0 = 3! ÷ 3!0! = 1

Probability = required outcome / Total possible outcomes

P(All 5 questions prepared for appears) :

[7C5 * 3C0] ÷ 10C5

(21 * 1) / 252

= 21 / 252

Answer:

144 I think????? ????????

Here's the solution,

Volume of wall :

=》total bricks × volume of each brick

=》1200 × 0.075 m³

=》90 m³

volume of wall :

=》lenght × width × height

=》25 × 9 × width

=》225 × width

now, by equating the volumes, we get

( since they are volume of same wall )

=》225 × width = 90

=》width = 90 ÷ 225

=》width of wall = 0.4 m

5ml=1 teaspoon

2.5ml=1/2 teaspoon

so 2.5ml is equal to half teaspoon

Answer:

D. 3/36, or 1/12

Step-by-step explanation:

The probability of rolling a sum equal to 10 on two six-sided number cubes is 3/36.

This is because of the 36 total outcomes, only 3 have a sum of 10.

In other words, the probability of rolling a sum equal to 10 is 3 in 36, or 3 out of 36 (3/36).

Answer:

[tex]46^{\circ}[/tex]

Step-by-step explanation:

Since the pair of angles are complimentary (add up to [tex]90^{\circ}[/tex]), as denoted by the right angle, we have the following equation:

[tex]44+x=90,\\x=90-44,\\x=\boxed{46^{\circ}}[/tex]

Answer:

46°

Step-by-step explanation:

ok first of all the angle looks like a 90° meaning 90 - 44 = 46

and the angle cant be above 120° anyways because 120 + 44 = 164

and the angle is way to small, 164° is almost a straight line, and so is 165° and 175° for the other answers

Answer:

p = 5/12

Step-by-step explanation:

-14+6p = -9-6p

Add 6p to each side

-14+6p+6p = -9-6p+6p

-14 +12p = -9

Add 14 to each side

-14+12p = -9 +14

12p =5

Divide by 12

12p/12 = 5/12

p =5/12
