card is randomly selected. What is the probability of selecting two odd numbers?

Answers

Answer 1

Answer:

Im not sure, but I can give advice!

Step-by-step explanation:

Study and wach yt vids (: hope I helped a bit!

Answer 2

Answer:

25/59

Step-by-step explanation:

Since there are 5 odd cards and 7 cards total, the probabilty of drawing an odd card is 5/7.

he probability of two events happening is the probability of each multiplied together, so multiply 5/7 by 5/7 to get 25/49.

They are also equal because the bisector AC bisects angle BAD and divides it into two equal angles which are angle B and angle D.It is given. Common side.Common angle.Two angles and one included side is equal so these two triangles are congruent under the ASA congruence criterion. Two sides and one included side is equal so these two triangles are congruent under the SAS congruence criterion as well.

Steps to derive these statements and reasons :

Given :

segment AB = segment ADsegment BC = segment DC∠B =∠Dsegment AC bisects ∠BAD

This means that △ABC≅△ADC under the SAS congruence criterion because according to this criterion if two sides and one included angle is equal two triangles are congruent and since these two triangles fulfill these rules they are said to be congruent under the SAS congruence criterion. But they are also congruent under the ASA congruence criterion which states that if two angles and one included side is equal two triangles are congruent. Since △ABC and △ADC fulfill these rules too they can said to be congruent under the ASA congruence criterion.

Which equation represents a line which is perpendicular to the line x – 2y = -14?

Answers

Answer:

any equation that have the slope of -2

A line which is perpendicular to the line x – 2y = -14 will have a slope of -2

What is a slope?

The slope of a line is a measure of its steepness.

Given an equation of a line  x – 2y = -14

We know that, the slope of a line perpendicular to another line will have a slope of its negative reciprocal.

Therefore, slope of the line perpendicular to the line x – 2y = -14  will be -2

Hence, equation of the line perpendicular to the line x – 2y = -14 will have a slope of -2

Answer:

46940064

Step-by-step explanation:

1)

The angle of inclination is the angle between the horizontal and the ramp.

Using the sine ratio in the right triangle formed by the ground and the ramp

let x be the angle of inclination, then

sinx = \frac{opposite}{hypotenuse}

hypotenuse

opposite

= \frac{0.7}{4.2}

4.2

0.7

, then

x = sin^{-1}sin

−1

(\frac{0.7}{4.2}

4.2

0.7

) ≈ 10° ( to the nearest degree )

(2)

Again there is a right triangle between the ground and the vertical height of the kite, with hypotenuse being length of string.

let y be the height of the kite and x the horizontal distance, then

sin27° = \frac{opposite}{hypotenuse}

hypotenuse

opposite

= \frac{y}{176}

176

y

( multiply both sides by 176 )

176 × sin27° = y , then

y ≈ 80m ( to the nearest metre ) ← height of kite

and

cos27° = \frac{adjacent}{hypotenuse}

hypotenuse

adjacent

= \frac{x}{176}

176

x

( multiply both sides by 176 )

176 × cos27° = x , then

x ≈ 157m ( to the nearest metre ) ← horizontal distance
