The linear functions are 1/3x=y-3 and y=2/3x. Therefore, options A and D are the correct answer.

A linear function is a function that represents a straight line on the coordinate plane. The highest power of the variable is one.

Given are some equation, from the options, we need to identify which is a linear function.

1/3x=y-3 is the linear function in two variables.

y=x³ is the cubic function.

y=6x² is the quadratic function.

y=2/3x is the linear function in one variable.

Therefore, the linear functions are 1/3x=y-3 and y=2/3x.

Step-by-step explanation:

5 x 8

or

repeated addition, 5+5+5+5+5+5+5+5

Add the colors together to get total pieces:

2 + 2 + 3 + 5 = 12 total pieces.

Blue and green = 2 + 2 = 4 pieces.

Picking blue of green would be 4/12 which reduces to 1/3

The answer is A. 1/3

Answer and Step-by-step explanation:

(a) Since the student have to stop when he gets to w softcover book, then the sample space should always stop at either 3 or 4 or 5. If the students examines the books randomly and stops at a softcover book, here are the possible ways he could carry this out,

S = {3, 4, 5, 13, 14, 15, 23, 24, 25, 123, 124, 125, 213, 214, 215}

2. Since only one book is to be examined then the student must check only one softcover book and end the examining. To do this, either he examines just 3 or 4 or 5. Therefore,

A = {3, 4, 5}

3. We need to pick the possibilities from the sample space that shows that the examining ended at book 5. Therefore,

B = {5, 15, 25, 125, 215}

4. We need to pick possibilities from the sample space that shows that book 1 was not examined. Therefore,

C = {3, 4, 5, 23, 24, 25}

Step-by-step explanation: It you start by getting rid of the 1/2x+1/2x it makes x=x/1. X/1 is x so x=x. X can be anything!

Answer:

  C.  41.0, θ = 77.3°

Step-by-step explanation:

The sum is ...

  5(8, 4) -3(-3, -4) +8(-5, 1) = (5·8-3(-3)+8(-5), 5·4-3(-4)+8·1)

  = (40+9-40, 20+12+8) = (9, 40)

The magnitude is ...

  √(9² +40²) = √1681 = 41

The angle is ...

  arctan(40/9) ≈ 77.3°

The resultant magnitude and direction is 41∠77.3°.

Answer:

41.0, θ = 77.3°

Answer:

X=-6

If satisfied, please mark brainliest

Step-by-step explanation:

-3x+8+5x=-4

Subtract 8 from both sides and add

2x=-12

X=-6

Step 1: Simplify both sides of the equation.

−3x+8+5x=−4

(−3x+5x)+(8)=−4(Combine Like Terms)

2x+8=−4

2x+8=−4

Step 2: Subtract 8 from both sides.

2x+8−8=−4−8

2x=−12

Step 3: Divide both sides by 2.

2x

Answer:

1) y = -1

2) y = 3

3) y = 5

4) y = 9

Step-by-step explanation:

1) when x = -2

y = 2x + 3

y = 2(-2) +3

y = -1

2) when x = 0

y = 2x + 3

y = 2(0) +3

y = 3

3) when x = 1

y = 2x + 3

y = 2(1) +3

y = 5

4) when x = 3

y = 2x + 3

y = 2(3) +3

y = 9

Answer:

See below.

Step-by-step explanation:

The unit rate is the cost per thing. You just divide the cost by the amount:

$7.38/18 ounces = $0.41/1 ounce

$15.39/27 ounces = $0.57/1 ounce

Therefore, $7.38 for 18 ounces is the better option.

Full question:

Suppose SAT scores among students are normally distributed with a mean of 500 and a standard deviation of 100.

If a college says it admits only people with sat scores among the top 10%. how high a sat score does it take to be eligible?

Answer and explanation:

To find where SAT score of student falls in the test given mean and standard deviation of scores, we can calculate: x-500/100 where x is number of SAT score of students

A sat score in the top 10% region would have a score better than 90% of other SAT scores. Therefore 0.90 has a z score of 1.28

We use algebra to find the score to be eligible thus:

1.28=x-500/100

x-500=128

x=128+500

x=628

Therefore to be eligible, a student needs to score at least 628, and be in the top 10% of scores

Answer:

Step-by-step explanation:

Answer:

43 < μ₁ - μ₂  < 49

Step-by-step explanation:

Sample 1:

Mean      x₁    =  88

Sample size    n₁  = 173

Sample standard deviation    s₁  =  12,22

Sample 2:

Mean      x₂    =  53,5

Sample size    n₂  = 127

Sample standard deviation    s₂  =  13,59

CI   95 %        α  =  5%    α = 0,05    α/2  = 0,025

We need to find:

(  x₁  -  x₂  ) - tα/2,v *√ (s₁²/n₁ ) + (s₂²/n₂) < μ₁ - μ₂  < (  x₁  -  x₂  ) + tα/2,v *√ (s₁²/n₁ ) + (s₂²/n₂)

v = degree of fredom    

v  = [ ( s₁²/n₁ + s₂²/n₂)² / (s₁²/n₁)² /n₁-1  + (s₂²/n₂)²/n₂-1

v =  [ (0,86 + 1,45 ) / 0,0043 +  0,017

v = 2,31 / 0,0213

v = 108

Then  t 0,025, 108  from t table is:  We will take v = 100

t = 1,984

Now

√ (s₁²/n₁ ) + (s₂²/n₂)  =  √ 0,86  + 1,43

√ 2,3   = 1,51

Then: CI:

(173 - 127 ) -  1,984*1,51    < μ₁ - μ₂  < ( 173 - 127 )  +  1,984*1,51

46 - 3  < μ₁ - μ₂  < 46 + 3

43 < μ₁ - μ₂  < 49
