Answer:

Step-by-step explanation:

The first change, the price goes from $4.09 to $3.59.

Beginning price: $4.09

The price decreased to: $3.59

Amount of decrease: $4.09 - $3.59 = $0.50

Percent of decrease: 0.5/4.09 * 100% = 12.2%

The second change, the price goes from $3.59 to $4.09.

Beginning price: $3.59

The price increased to: $4.09

Amount of increase: $4.09 - $3.59 = $0.50

Percent of increase: 0.5/3.59 * 100% = 13.9%

The first change was a decrease of 12.2%, and he second change was an increase of 13.9%. The two percent changes are not the same, and the second percent change is greater.

The weatherman predicts a 20% chance of rain on Thursday. If it rains, there is a 10% chance that your roof will leak. (If it doesn't rain, of course, your roof is safe.) What is the chance that you will have a leaky roof on Thursday

Answers

Answer:

2%

Step-by-step explanation:

Probability of rain, P(R) = 0.2

Probability of leak Given that it rains, P(L|R) = 0.1

Probability of leak Given that it does not rain, P(L|R') = 0

According to Baye's Rule:

P(L) = [P(L|R) * P(R)] + [P(L|R') * P(R')]

P(R') = 1 - P(R) = 1 - 0.2 = 0.8

P(L) = [0.1 * 0.2] + [0 * 0.8]

P(L) = 0.02 + 0

P(L) = 0.02

Hence, probability of a roof leak on Thursday is 0.02 = (0.02 * 100%) = 2%

Question: The two angles below form a linear pair and are therefore supplementary solve for X. (Geometry)

Answers

Answer:

x = 29

Step-by-step explanation:

(2x - 13)° + (7x - 68)° = 180° (linear pair angles add up to 180°)

Solve for x

2x - 13 + 7x - 68 = 180

Add like terms

9x - 81 = 180

Add 81 to both sides

9x = 180 + 81

9x = 261

Divide both sides by 9

x = 261/9

x = 29

Consider a sequence given by the formula f(n)=3n-1 starting with n=1. Generate the first 5 terms of the sequence

Answers

Answer:

The first 5 terms are 2, 5, 8, 11, 14.

Step-by-step explanation:

You use the formula to find out each term.f(n)=3n-1 starting with n=1. If n=1 that is the 1st term, if n=2 that is the 2nd term, and so on. n means what number term it is. Now to find each term: n=1: f(1)= 3(1)-1= 3-1= 2 The 1st term is 2n=2: f(2)= 3(2)-1= 6-1= 5 The 2nd term is 5n=3: f(3)= 3(3)-1= 9-1=8 The 3rd term is 8n=4: f(4)= 4(3)-1= 12-1= 11 The 4th term is 11n=5: f(5)= 5(3)-1= 15-1= 14 The 5th term is 14

So the first 5 terms are 2,5,8,11,14

Determine whether the underlined numerical value is a parameter or a statistic. Explain your reasoning. A survey of 32 out of 50 in a basketball game showed 20.5% enjoyed the game.

Answers

Answer: statistic.

Step-by-step explanation:

A parameter is a measure of characteristic in a population.

A statistic is a measure of characteristic in a sample.

Given: A survey of 32 out of 50 in a basketball game showed 20.5% enjoyed the game.

Since group of 32 games out of 50 is representing a sample here.

So, 20.5% is the measure of sample, i.e. it is a statistic.

In ΔEFG and ΔYXZ, m∠F ≅ m∠X and m∠E ≅ m∠Y. If m∠E = 62° and m∠X = 80°, what is the measure of ∠Z?

Triangles EFG and YXZ, in which triangle YXZ is larger than EFG.


{Please look at the comments for the answer}

A) 38°
B) 62°
C) 80°
D) 142°​

Answers

Answer: A) 38°

Step-by-step explanation:

Given: In ΔEFG and ΔYXZ, m∠F ≅ m∠X and m∠E ≅ m∠Y. If m∠E = 62° and m∠X = 80°.

So,  m∠F = m∠X  = 80°  

m∠Y = m∠E =  62°

By angle sum property , the sum of all angles in a triangle is 180 degrees.

In ΔXYZ ,

∠ X  + ∠Y + ∠Z = 180°

⇒ 80°+ 62°+ ∠Z = 180°

⇒ 142°+∠Z = 180°

⇒ ∠Z = 180°-142°

⇒ ∠Z = 38°

Hence, the correct option is A) 38°.

Answer:

the answer is A, 38 degrees
