Based on the number of times Johnny performs the experiment, the order from the largest difference in relative frequency and actual prob. to the smallest is:

The difference between absolute probability and relative frequency will be larger if the number of experiments performed is smaller.

This is why the largest difference was seen when Johnny performed the experiment 20 times and the smallest difference was seen when the experiment was done 75 times.

Expanding the product gives

(2 - 3i) (4 + 3i) = 8 - 12i + 6i - 9i² = (8 + 9) + (6 - 12) i = 17 - 6i

so a = 17.

Answer:

a^3 + b^3

Step-by-step explanation:

(a + b)(a^2-ab+b^2)

a(a^2 -ab +b^2) +b(a^2-ab+b^2)

a^3 - a^2b +ab^2 + ba^2 -ab^2 +b^3

a^3 -a^2b +a^2b ab^2-ab^2 + b^3

The final answer will then be:

a^3 + b^3

The situation in which triangles will be made congruent for sure is given by: Option ( iii ) Both making a triangle TRY with right angle at T and sides TR =4 cm and RY =5cm

Suppose it is given that two triangles ΔABC ≅ ΔDEF

Then that means ΔABC and ΔDEF are congruent. Congruent triangles are exact same triangles, but they might be placed at different positions.

The order in which the congruency is written matters.

For ΔABC ≅ ΔDEF, we have all of their corresponding elements like angle and sides congruent.

Thus, we get:

[tex]\rm m\angle A = m\angle D \: or \: \: \angle A \cong \angle D \angle B = \angle E\\\\\rm m\angle B = m\angle E \: or \: \: \angle B \cong \angle E \\\\\rm m\angle C = m\angle F \: or \: \: \angle C \cong \angle F \\\\\rm |AB| = |DE| \: \: or \: \: AB \cong DE\\\\\rm |AC| = |DF| \: \: or \: \: AC \cong DF\\\\\rm |BC| = |EF| \: \: or \: \: BC \cong EF[/tex]

(|AB| denotes length of line segment AB, and so on for others).

For two triangles being congruent, we need at least:

Checking all the options:

Only one side and one angle are not enough.

Two equilateral triangles are not necessary to be congruent. Example, one equilateral triangle has sides of 3 units, and other triangle has sides of 5 units.

Two sides TR and RY and a non-included angle T is given. This doesn't satisfy SAS' condition. But since it is given that:

Angle T is right angled, so we now know that RY is going to be hypotenuse.

Using this fact, and the fact that |RY| = 5 cm, |TR| = 4 cm, and Pythagoras theorem, we can get |TY| = 3 cm.

Thus, it will complete SSS condition, and therefore, by SSS congruency, the triangles made in this case would be congruent.

All angles(corresponding) being equal implies similarity, but not congruence.

Thus, the situation in which triangles will be made congruent for sure is given by: Option ( iii ) Both making a triangle TRY with right angle at T and sides TR =4 cm and RY =5cm

2:4 when divided by 2 gets you 1:2

and 2:4 multiplied by 2.5 gets you 5:10

Answer:

B and D

Step-by-step explanation:

So basically we have to find the unit rate of 2:4.

(remember to find the unit rate we have to simplfy the ratio until one of the quantities is 1)

2:4 (divide by 2 on each side)

1:2 (B)

now we can use this unit rate of 1:2 to find out other equal ratios

1:2 (multiply 5 on both sides)

5:10 (D)

Answer:

(a) 5 units up

(b) 3 units right

(c) 7 units left

Step-by-step explanation:

Parent equation:  [tex]y=x^2[/tex]

Transformed equation:  [tex]y = (x - h)^2+ k[/tex]

h translates the parabola horizontally

If h > 0 then the translation is h units to the right.

If h < 0 then the translation is h units to the left.

If h = 0 then there is no horizontal translation.

k translates the parabola vertically

If k > 0 then the translation is k units up.

If k < 0 then the translation is k units down.

If k = 0 then there is no vertical translation.

Part (a)

Given equation:  [tex]y=x^2+5[/tex]

Rewriting in transformed equation form:  [tex]y=(x-0)^2+5[/tex]

Therefore, the parabola is translated 5 units up.

Part (b)

Given equation:  [tex]y=(x-3)^2[/tex]

Rewriting in transformed equation form:  [tex]y=(x-3)^2+0[/tex]

Therefore, the parabola is translated 3 units right.

Part (c)

Given equation:  [tex]y=(x+7)^2[/tex]

Rewriting in transformed equation form:  [tex]y=(x+7)^2+0[/tex]

Therefore, the parabola is translated 7 units left.

Part (d)

Answer:

72 in²

Step-by-step explanation:

since the trap is open left and right, we don't include these side areas.

so, all we have for the surface area are

the top rectangle (2.5 in × 12 in),

the bottom rectangle (2 in × 12 in)

the back rectangle (1.5 in × 12 in)

for the total surface area we need to to add all 3 areas up.

in our case we get

2.5 × 12 = 30 in²

2 × 12 = 24 in²

1.5 × 12 = 18 in²

total is then

30 + 24 + 18 = 72 in²
