Note that:

I = 1, V = 5, X = 10, L = 50, C = 100

XX = 20, II = 2

20 + 2 = 22

XXII = 22

Find the number on the next page (pg.23)

23 = XXIII

XXIII is your answer

hope this helps

7/20 in decimal form

zhannawk [14.2K]

Well, we would have to divide 7 into 20 in order to find the decimal, so 7 divided by 20 = 0.35, so 7/20 as a decimal is 0.35, and if you move the decimal two places to the left, it is also 35%.
I hope I helped! =D

The width of a rectangle is 7t-1.5 feet and the length is 1.5t + 8 feet. Find the perimeter of the

Tasya [4]

Step-by-step explanation:

✧ $\underline{ \underline{ \large{ \tt{ \: G \: I\:V \: E \: N}}}} :$

Width of a rectangle ( w ) = 7t - 1.5 ft
Length of a rectangle ( l ) = 1.5t + 8 ft

✧ $\underline{ \underline{ \large{ \tt{ \: T \: O\: F\: I \: N \: D}}}} :$

Perimeter of the rectangle

✧ $\underline{ \underline{ \large{ \tt{S \: O \: L \: U \: T \: I\: O \: N}}}} :$

❀ $\boxed{ \large{ \text{Perimeter \: of \: a \: rectangle \: = \: 2(l + w)}}}$

⟶ $\large{ \tt{2(1.5 \: t \: + 8 \: + 7t - 1.5}})$

⟶ $\large{ \tt{2(1.5t + 7t + 8 - 1.5)}}$

⟶ $\large{ \tt{2}(8.5t + 6.5)}$

⟶ $\large{ \tt{17t + 13}}$

☄ $\underline{ \boxed{ \boxed{ \tt{Our \: final \: answer : \underline{ \boxed{17t + 13 feet}}}}}}$

Hope I helped ! ♡

Given PRQ = XYZ, sketch a diagram and state all corresponding sides and angles.

Kazeer [188]

Given that ΔPQR ≅ ΔXYZ, then the corresponding angles are:

∠P ≅ ∠X

∠Q ≅ ∠Y

∠R ≅ ∠Z

From the picture, the corresponding sides are:

PQ ≅ XY

QR ≅ YZ

RP ≅ ZX

Linear equation 5v=-6v-33

s344n2d4d5 [400]

Step 1: Add 6v to both sides.

5v+6v=−6v−33+6v

11v=−33

Step 2: Divide both sides by 11.

11v

−33

v=−3

answer: v=−3

alexira [117]

Answer:

Given that a person was identified as a future terrorist, there is a 2.8544% probability that he/she actually is a future terrorist.

Step-by-step explanation:

There are 1000 future terrorists in a population of 300,000,000. So the probability that a randomly selected person in this population is a terrorist is:

$P = \frac{1,000}{300,000,000} = 0.000003 = 0.0003%$

So, we have these following probabilities:

A 99.9997% probability that a randomly chosen person is not a terrorist.

A 0.0003% probability that a randomly chosen person is a terrorist.

A 98% probability that a future terrorist is correctly identified

A 99.9% chance of correctly identifying someone who is not a future terrorist. This also means that there is a 0.01% probability of someone who is not a terrorist being identified as one.

This can be formulated as the following problem:

What is the probability of B happening, knowing that A has happened.

It can be calculated by the following formula

$P = \frac{P(B).P(A/B)}{P(A)}$

Where P(B) is the probability of B happening, P(A/B) is the probability of A happening knowing that B happened and P(A) is the probability of A happening.

Here we have:

What is the probability that the person is a terrorist, given that she was identified as a terrorist.

P(B) is the probability that the person is a terrorist. So $P(B) = 0.000003$

P(A/B) is the probability that the person was identified as a terrorist, given that she is a terrorist. The problem states that the system has a 98% chance of correctly identifying a future terrorist, so $P(A/B) = 0.98$
