At Brighton Middle School, Mr. Yule asked 50 randomly selected students from each grade level about their favorite subject, and
Ugo [173]

Answer:

Yes, he made a reasonable inference by saying about 25 percent of students choose the science.

Step-by-step explanation:

Given that

Number of students for survey = 50

Number of students who choose science = 12

Now

Percentage of student who choose science = \frac{12}{50} x 100

Percentage of student who choose science = \frac{12*100}{50}

Percentage of student who choose science = 24 %

Now as Mr. Yule said "about 25" percent of students choose the science it can be treated as reasonable approximation.

Now if the number of students in survey become 200, then we can expect 12 out of every 50 students would choose the science. So, in total 48 students would choose the science.

Now lets calculate the percentage of students who choose science.

Percentage of student who choose science = \frac{48}{200} x 100

Percentage of student who choose science = \frac{48*100}{200}

Percentage of student who choose science = 24 %

Suppose you received a job offer with a starting salary of $48,500 per year and a guaranteed raise of $1200 per year. Find the n
LuckyWell [14K]

Answer:

  • 7 years

Step-by-step explanation:

<u>This is going to be an arithmetic progression:</u>

  • 48500, 48500 + 1200, 48500 + 1200*2, ...

<u>So the first term is </u>

  • a₁ = 48500

<u>and the common difference is </u>

  • d = 1200

<u>Sum of AP is:</u>

  • S = (a₁ + aₙ)*n/2 = (2a₁ + (n - 1)d)*n/2

<u>Substitute and solve for n:</u>

  • (2*48500 + (n - 1)*1200)*n/2 = 321000
  • (97000 + 1200n - 1200)n = 642000
  • 1200n² + 95800n - 642000 = 0
  • 6n² + 479n - 3210 = 0

<u>Solving we get a positive root of:</u>

  • n ≈ 6.21 and it rounds up to 7 years

The answer is [ yes; ΔABC ~ ΔFGH by SAS Similarity ]

SAS Similarity states that two triangles have congruent corresponding angles and the corresponding sides have an identical ratio

The angle measure aren't given but the angles look to be the same.

To find the scale factor, divide.

12 / 8 = 1.5

15 / 10 = 1.5

The corresponding sides have an identical ratio.

This proves that option B is correct.

Best of Luck!
