Algebra 1 Unit 4 Mid Quiz

Answers

Answer 1
Answer. Option A. y>3x+2
Explanation. Because the line is dotted, we know it is a > equation. We know that in slope-intercept form, the mx stands for is the slope (rise over run), by looking at the graph, we find that the slope is in fact 3 (or 3/1). For the second part of the equation, we know it’s the y-intercept; therefore, option A is correct because the y-intercept is in fact 2. Hope this helps, let me know if it’s correct so others can use it :)
Good luck.
Answer 2

The inequality that represents this graph is y < 2x + 2.

What are inequalities and their types?

Inequality is a relation that compares two numbers or other mathematical expressions in an unequal way.

The symbol a < b indicates that a is smaller than b.

When a > b is used, it indicates that a is bigger than b.

a is less than or equal to b when a notation like a b.

a is bigger or equal value of an is indicated by the notation a b.

The dotted line represents strictly less than or greater than.

From the graph, we can conclude that when x = 0, y = 2, and when x = 1 y = 4, and values of y are strictly less.

∴ The inequality that represents this graph is y < 2x + 2.

How do you do these questions?

Answers

Step-by-step explanation:

(a) Fₙ₋₁ > 0, so Fₙ₊₁ > Fₙ.  Each term is bigger than the one before it, so the function is increasing, meaning the series will diverge to infinity.

(b) Fₙ₊₁ / Fₙ = (Fₙ + Fₙ₋₁) / Fₙ

Divide.

Fₙ₊₁ / Fₙ = 1 + (Fₙ₋₁ / Fₙ)

Rewrite the second fraction using negative exponent.

Fₙ₊₁ / Fₙ = 1 + (Fₙ / Fₙ₋₁)⁻¹

Take the limit of both sides as n approaches infinity.

lim(n→∞) Fₙ₊₁ / Fₙ = 1 + lim(n→∞) (Fₙ / Fₙ₋₁)⁻¹

Substitute with φ.

φ = 1 + φ⁻¹

Solve.

φ² = φ + 1

φ² − φ − 1 = 0

φ = [ -(-1) ± √((-1)² − 4(1)(-1)) ] / 2(1)

φ = (1 ± √5) / 2

Since the ratio can't be negative:

φ = (1 + √5) / 2

Answers

Answer:

Shown below.

Step-by-step explanation:

The table showing the umber and frequency of a certain ocean's hurricanes annually from 1930 through 2005 is:

   Number:     0     1      2     3      4    5     6     7    8     11     12      

Frequency:    5    16    20   14      3    5     4     4    2      1       1

The probability of an events, say E is the ratio of the number of favorable outcomes to the total number of outcomes.

[tex]P(E)=\frac{n(E)}{N}[/tex]

Compute the probabilities of 0 - 12 hurricanes each season as follows:

Number Frequency Probability

     0       5             0.07

     1              16                   0.21  

     2     20             0.27

You track inventory at a furniture store. On Monday, the delivery truck delivers 15 new mattresses. Your team sells seven mattresses on Monday, two mattresses on Tuesday, zero on Wednesday, and five on Thursday. You receive a new order Friday morning of 15 mattresses. How many mattresses do you now have available?

Answers

Answer: 16

Step-by-step explanation: You started with 15 , you lose 7 Monday which leaves you with 8 , 2 on Tuesday which leaves you with 6 , 5 on Thursday which leaves you with 1 and then you received 15 on Friday which brings you to 16

The number of mattresses available now is 16.

Given that, On Monday, the delivery truck delivers 15 new mattresses. Number of mattresses sold on Monday=7, number of mattresses sold on Tuesday=2, number of mattresses sold on Wednesday=0, and number of mattresses sold on Thursday=5.

What is an equation?

Equations are mathematical statements containing two algebraic expressions on both sides of an 'equal to (=)' sign. It shows the relationship of equality between the expression written on the left side with the expression written on the right side. In every equation in math, we have, L.H.S = R.H.S (left hand side = right hand side). Equations can be solved to find the value of an unknown variable representing an unknown quantity.

Let number of mattresses do you now have available be x.

Given that, receive a new order Friday morning of 15 mattresses.

So, x=15-(7+2+0+5)+15

=30-14=16

Therefore, the number of mattresses available now is 16.

Daniel has to carry 32 boxes to his room. He can
carry 4 boxes on each trip. How many trips will
Daniel take? Show your work?

Answers

32 divided by 4= 8
So 8 trips in total

Daniel will take 8 trips.

What is division?

The division is one of the four basic mathematical operations, the other three being addition, subtraction, and multiplication.

Now it is given that,

Number of boxes = 32

Number of boxes can be carried in each trip  = 4

So, Number of trips = Number of boxes / Number of boxes can be carried in each trip

⇒ Number of trips = 32/4

⇒ Number of trips = 8

this is the required number of trips Daniel will take.

Thus, Daniel will take 8 trips.

Answer:

0<y<8

Step-by-step explanation:

So, as you can see by the graph, the y axis has a plot as low as 0. soo it would be 0. Then the highest plot is marked as high as 8. Therefore its 0<y<8.

The range of the function will be; Range = {y | 0<y<8 }. Then the correct option is A.

What is a function?

A statement, principle, or policy that creates the link between two variables is known as a function. Functions are found all across mathematics and are required for the creation of complex relationships.

We know that domain means all the possible values of x and the range means all the possible values of y.

So, as we can see by the graph, the y axis has a plot as low as 0. it would be 0. Then the highest plot is marked as high as 8.

The domain of the function is (0, 8] and the range of the function will be

Range = {y | 0<y<8 }

Then the correct option is A.
