what is the name of this system? consistent and dependent, consistent and independent, or inconsistent?
Answers
If a system has at least one solution, it is said to be consistent .
For system to be independent,
If a consistent system has exactly one solution, it is independent .
For system to be dependent,
If a consistent system has an infinite number of solutions, it is dependent .
The graph is given in the question tab which has exactly one solution.

100% D IN Use the information to answer the question. A store sells jump ropes. Each jump rope costs the same amount. During a sale, the store reduces the price of each jump rope by $1.90. Ma spends $12.78 on 2 jump ropes at the sale price. What was the price of 1 jump rope before the sale? Enter the answer in the box. $
Answers
Answer : $8.29
A shop sells jump ropes
Ma spends $12.78 on 2 jump ropes after removing $1.90 on each jump rope
Since, she spents $12. 78 on two jump ropes
$1.90 is removed from each
For the two jump rope, we have
2 x 1.90 = $3.80
This means $3.80 is removed from the two jump ropes
The total amount spents on the two jump rope before the removal is
$12.780 + $3.80
The total amount = $16.58
The total amount spents on the two jump ropes before the sales is $16.58
Since each jump rope cost the same price
Then
16.58/2 = $8.29
Therefore, the price of each jump rope is $8.29

a student says that the solution of 375=x-28 is 347 explain the students error and find the correct answer
Answers
The given equation is:
375 = x - 28
To solve the equation:
Collect like terms
The -28 crosses the equality sign to the left and becomes 28
The equation then becomes:
375 + 28 = x
x = 403 (correct answer)
The students error is that when he collected like terms, he did not change the "-" sign in -28 to +
He did 375 - 28 = x
x = 347 (wrong)

The numeric sentence (A) 6 × (5 + 8) = (6 × 5) + 8 represents the distributive property of multiplication.
What is the distributive property of multiplication?The distributive property of binary operations in mathematics generalizes the distributive law, which states that in elementary algebra, equality is always true. According to the distributive property of multiplication, the first number can be distributed among both of the other numbers and multiplied by each of them independently before adding the results to produce the same outcome as multiplying the first number by the sum.So, the distributive property of multiplication:
a × (b + c) = (a + b) × cSo, in the given options, only option (A) is similar to the distributive property of multiplication.
Therefore, the numeric sentence (A) 6 × (5 + 8) = (6 × 5) + 8 represents the distributive property of multiplication.

Daniel took 12 index cards and wrote the number 1 through 12 on them 1 number of each card. he then collected the cards, shuffled them, and drew one card from the stack. what is the probability that the number on the card is greater than 0
Answers
We have 12 cards, each one with a different number, so the probability of each card being picked is 1/12.
Since all these cards have numbers that are greater than 0, all the 12 cards are correct options to being picked.
Adding the probability of all 12 cards, we have 12/12, that is, 1 or 100%.
So the probability of picking a card with a number greater than 0 is 1 or 100% (that is, every card has a number greater than 0).

We can create the solution with the following tree diagram:
Part 2
For this case we want this probability:
P(rain and accident)
And we can do this operation:
P(rain and accident) = 0.75 *0.5 = 0.375
Part 3
For this case we want this probability:
P( no rain and accident)
And we can do this operation:
P(no rain and accident) = 0.25 *0.25 = 0.0625
Part 4
P(Accident) = 0.5*0.75 + 0.25*0.25= 0.4375

Answers
7680 bats are expected to be in the colony after 8 years
What is Exponential Decay?A quantity is subject to exponential decay if it decreases at a rate proportional to its current value.
The formula for exponential growth
[tex]y=ab^{t}[/tex]
Given,
After 2 years, there were 120 bats.
120=ab²...1
After 5 years, there were 960 bats.
960=ab⁵....2
Hence:
120/960 = ab²/ab⁵
1/8 = b²/b⁵
1/8 = 1/ b³
1/2³ =1/ b³
2³=b³
b=2
We solve for a
120 = ab²...... Equation 1
120 = a × 2²
120 = 4a
a = 120/4
a = 30
Now put a, b and t value in the formula
y = 30 × 2⁸
y = 7680 bats
Hence, 7680 bats are expected to be in the colony after 8 years
