The system of equations 4x-y=4(x+1) , y = 6 has:
A. one solution
B. infinitely many solutions
C. no solution

Answers

Answer 1

The system of equations 4x-y=4(x+1) and y=6 has no solution.

To determine the solution(s) of the system of equations, let's analyze each equation:

Equation 1: 4x - y = 4(x + 1)

Equation 2: y = 6

To simplify Equation 1, we can distribute 4 on the right side:

4x - y = 4x + 4

By rearranging terms, we have:

- y = 4

Comparing Equation 2 with this result, we see that the two equations are contradictory. Equation 2 states that y = 6, while the modified Equation 1 states that y = -4. This means there is no value of y that can simultaneously satisfy both equations.

Thus, the system of equations has no solution.

Therefore, the correct answer is C. no solution.

Carlos’s hockey team has ten players, not counting the goalie.Five non goalie players need to be selected for a starting line-up.

A)How many different starting lineups are possible if positions are not assigned?

B)How many starting lineups are possible if positions are assigned?

Answers

Final answer:

There are 252 different starting lineups possible if positions are not assigned, and 30,240 starting lineups are possible if positions are assigned.

Explanation:

For part A of the question, where positions are not assigned, we can calculate the number of different starting lineup combinations by using the combination formula. Since we are choosing 5 players out of 10 without regard to order, we use:

C(n, k) = n! / (k!(n-k)!)

Where n is the total number of players to choose from, and k is the number of players we want to choose. Therefore, we have:

C(10, 5) = 10! / (5! (10-5)!) = 252

There are 252 different starting lineups possible if positions are not assigned.

For part B, where positions are assigned, we use the permutation formula because the order in which we select the players matters. This formula is:

P(n, k) = n! / (n-k)!

Since the order in which the players are chosen matters, we have:

P(10, 5) = 10! / (10-5)! = 30,240

There are 30,240 different starting lineups possible with positions assigned.

A cardboard sheet is cut in the shape of a triangle, with vertices at (0,0), (20,0), and (3,4) units. the thickness of the sheet is uniform. what is the x-coordinate of its center of mass?

Answers

This problem can be solved in two ways, the long way, or the short way.

1. The long way
We know that the base of the triangle is along the x-axis, and the length of the base is 20.
The centre of mass is located at 2/3 of the distance from vertex (3,4) along the median, which cuts the base at (10,0).
Therefore the centre of mass is located at
x=3+(10-3)*2/3=23/3
y=4/3

2. The short way
It turns out that the centre of mass of a triangle sheet is located at the mean of the coordinates of the three vertices, i.e.
CG=((0+20+3)/3, (0+0+4)/3)=(23/3, 4/3)  as before.

A gardener crosses tall true-breeding pea plants with short true-breeding ones. Tall plants are dominant to short ones. He collects the seeds to grow F1 plants and then allows them to self-pollinate to form an F2 generation. Which of the following describes the traits of the offspring correctly?

Answers

The responses given are as follows;
a) Three–fourths of the F1 and one–half of the F2 plants will be tall.
b) All of the F1 and three–fourths of the F2 plants will be tall.
c) Three–fourths of the F1 and all of the F2 plants will be tall.

Let’s name tall as T and short as t
Since both are true breeding plants
Tall plants have the genotype TT and short plants have the genotype tt
Tall plants will make gametes of type T only
Short plants make gametes of type t only
After cross breeding the offspring would all be of genotype Tt as they’re made of T and t gametes
F1 generation formed have the genotype Tt
Since T is dominant all F1 plants are tall
When F1 self pollinates
F1 * F1
Tt *Tt
Gametes are
T t T t
F2 population offspring genotypes are as follows;
TT -1/4 tall
Tt -1/4 tall
Tt -1/4 tall
tt - 1/4 short
3/4 of the plants are tall
Remaining 1/4 is short

Therefore response b is correct
All f1 plants are tall and 3/4 of f2 plants are tall

If the APY of a savings account is 5.3%, and if the principal in the savings account is $5100 for an entire year, what will be the balance of the savings account after all the interest is paid for the year?
A. $5300.00
B. $5127.03
C. $5100.00
D. $5370.30

Answers

the answer is D. hope this helps

Answer:

Option D - $5370.30

Step-by-step explanation:

Given : If the APY of a savings account is 5.3%, and if the principal in the savings account is $5100 for an entire year.

To find : What will be the balance of the savings account after all the interest is paid for the year?          

Solution :

First we find the interest he paid.

The interest formula is [tex]I=P\times R\times T[/tex]

Where, P is the principal P=$5100

R is the rate of interest R=5.3%=0.053

T is the time T=1 year

Substituting the values,

[tex]I=5100\times 0.053\times 1[/tex]              

[tex]I=\$270.3[/tex]                  

The balance of the saving account is the sum of interest paid and principal value.

Amount = Interest +Principal

Amount = $270.3 +$5100          

Amount = $5370.3

Therefore, Option D is correct.

The length, l, of the garden is twice its width w.
Three of these equations give the correct value for w.

Which equation does NOT?



2 • w + 2 • 2w = 60


2 • (2w + w) = 60


w + 2w = 60


w + 2w + w + 2w = 60

Answers

w + 2w = 60 would be your answer.

Answer:

w + 2w = 60

Step-by-step explanation:

w + 2w = 60

This equation will not give you the correct value for W because W is the siez or represents the size of the smaller side, since you have 4 sides, 2 small and 2 big, the sum of this 4 sides will be the perimeter, or the total meters of fence needed, since the total meter of fence need is 60 and in the equation you just have 2 sides, the value for W will be double than the real.

Noel is playing a game where he draws one playing card each out of two stacks of 5 cards. The table below shows all possible sums for the two numbers on the cards.

Answers

Noel is more likely to draw two cards with a sum that is greater than 13.

To determine which outcome is more likely, let's count the number of combinations that meet each criterion.

1. **Sum that is a multiple of 3**:

  - Possible sums: 3, 6, 9, 12

  - Counting the combinations:

    - 3: 1 combination

    - 6: 2 combinations

    - 9: 3 combinations

    - 12: 4 combinations

  - Total combinations: 1 + 2 + 3 + 4 = 10 combinations.

2. **Sum greater than 13**:

  - Possible sums: 14, 15, 16, 17, 18, 19, 20, 21, 22, 23

  - Counting the combinations:

    - 14: 1 combination

    - 15: 2 combinations

    - 16: 2 combinations

    - 17: 3 combinations

    - 18: 2 combinations

    - 19: 3 combinations

    - 20: 2 combinations

    - 21: 3 combinations

    - 22: 1 combination

    - 23: 1 combination

  - Total combinations: 1 + 2 + 2 + 3 + 2 + 3 + 2 + 3 + 1 + 1 = 20 combinations.

Comparing the total combinations, we see that there are more combinations with a sum greater than 13 (20 combinations) than there are combinations with a sum that is a multiple of 3 (10 combinations). Therefore, Noel is more likely to draw two cards with a sum that is greater than 13.

The probable question may be:

Noel is playing a game where he draws one playing card each out of two stacks of 5 cards. The table below shows all possible sums for the two numbers on the cards.

3, 6, 7, 9, 1

1 = 4, 7, 8, 10, 12

4 = 7, 10, 11, 13, 15

6 = 9, 12, 13, 15, 17

8 = 11, 14, 15, 17, 19

12 = 15, 18, 19, 21, 23

Is Noel more likely to draw two cards with a sum that is a multiple of 3 or two cards with a sum that is greater than 13?

Noel is more likely to draw two cards with a sum greater than 13, as there are 37 combinations compared to 11 combinations for multiples of 3.

To determine whether Noel is more likely to draw two cards with a sum that is a multiple of 3 or two cards with a sum that is greater than 13, we can analyze the table provided.

1. Sum that is a multiple of 3:

  - There are several combinations of card values that result in a sum that is a multiple of 3. We can count these combinations from the table:

    - (3, 4), (3, 7), (3, 9), (3, 12)

    - (6, 7), (6, 10), (6, 12)

    - (7, 8), (7, 11)

    - (9, 10), (9, 13)

    - (11, 12)

2. Sum greater than 13:

  - We need to count the combinations of card values that result in a sum greater than 13:

    - (6, 8), (6, 10), (6, 11), (6, 12), (6, 13), (6, 15), (6, 17)

    - (7, 8), (7, 9), (7, 10), (7, 11), (7, 12), (7, 13), (7, 15), (7, 17), (7, 19)

    - (9, 10), (9, 11), (9, 12), (9, 13), (9, 15), (9, 17), (9, 19)

    - (11, 12), (11, 13), (11, 15), (11, 17), (11, 19)

    - (12, 13), (12, 15), (12, 17), (12, 19)

    - (13, 15), (13, 17), (13, 19)

    - (15, 17), (15, 19)

    - (17, 19)

After counting the combinations, we can compare the number of combinations in each category:

1. Sum that is a multiple of 3:

  - Total combinations: 11

2. Sum greater than 13:

  - Total combinations: 37

Comparing the totals, we can see that Noel is more likely to draw two cards with a sum that is greater than 13, as there are more combinations resulting in this outcome.

Write the following decimal number in its equivalent fraction form. Show all work for full credit.
0.8(repeating)

Answers

Let x=0.8888... 

x=0.8888 Start with the given equation 

10x=8.8888 Multiply both sides by 10. The goal is to move the decimal point to the next repeating portion (which is just one spot to the right) 



 Now subtract the equation x=0.8888 from 10x=8.8888 to get 
10x-x=8.8888-0.8888 

9x=8 Combine like terms. Notice how the decimal portions cancel out. 

x=8/9 Divide both sides by 9 to isolate x 

So the answer is x=8/9 which means that 8/9=0.8888 (where the 8's repeat)
 
Final answer:

To write the decimal number 0.8(repeating) as a fraction, use the concept of an infinite geometric series and convert it to an equation. Multiply both sides of the equation by 10 to eliminate the decimal point and subtract the original equation to eliminate the repeating part. Finally, divide by 9 to get the equivalent fraction form.

Explanation:

To write the decimal number 0.8(repeating) as a fraction, we can use the concept of an infinite geometric series. Let's assume the repeating decimal as x: x = 0.8(repeating). Now, multiply both sides of the equation by 10 to remove the decimal point: 10x = 8(repeating). Next, subtract the original equation from this new equation to eliminate the repeating part: 10x - x = 8(repeating) - 0.8(repeating). Simplifying these expressions gives us: 9x = 7.2. Finally, divide both sides of the equation by 9: x = 7.2/9. Therefore, the equivalent fraction form of 0.8(repeating) is 7.2/9.

How many 4-sequences on {0..9} do not begin with 0?

Answers

I take a [tex]n[/tex]-sequence to mean any permutation of the digits 0-9 of length [tex]n[/tex]. Furthermore, I'm assuming no number can be repeated.

If that's the case, then for any 4-sequence, the first digits place (leftmost) has 9 possible choices (1-9). Once that number is used up, we have 9 numbers left in the pool of digits, from which we select a 3-sequence. The number of possible 3-sequences would be [tex]\dfrac{9!}{3!}=60,480[/tex]. Multiply this by 9 (to account for the first digit's possibilities) and we get a grand total of [tex]\dfrac{9\times9!}{3!}=544,320[/tex] possible 4-sequences on [tex]\{0,\ldots,9\}[/tex].

There are 9000 possible 4-sequences that do not begin with the digit 0.

The question asks how many 4-sequences on the set {0..9} do not begin with 0. To solve this, we need to consider the number of possible options for each of the four positions in the sequence, knowing that the first digit cannot be 0.

For the first position, there are 9 options (1-9), since 0 is not allowed. For the next three positions, each can be any of the 10 digits (0-9), since there are no restrictions. Thus, the total number of such sequences is the product of the number of options for each position.

9 options (1st position) x 10 options (2nd position) x 10 options (3rd position) x 10 options (4th position) = 9 x 10 x 10 x 10 = 9000.

So, to find how many 4-sequences do not begin with 0, multiply the number of choices for each position: 9 (first position, cannot be 0) x 10 (second position) x 10 (third position) x 10 (fourth position), resulting in 9000 such sequences.
