ANSWER
No solution
EXPLANATION
The first equation is
[tex]y = {x}^{2} - 2x[/tex]
and the second equation is
[tex]y = - 2x - 1[/tex]
We equate the two equations to obtain;
[tex] {x}^{2} - 2x = - 2x - 1[/tex]
This implies that
[tex] {x}^{2} = - 2x + 2x - 1[/tex]
[tex] {x}^{2} = - 1[/tex]
There is no real number whose square is -1.
Therefore, the equation has no solution.

True or False: mean and median sometimes have the same values
Answer: True
For example, the mean and median of any arithmetic function is equivalent.
Answer:
True
Step-by-step explanation:
Averages are sometimes called "measure of central tendency". In a distribution with a positive skew, the median has a higher value than the mean. In a normal distribution, the mean, median and mode have the same value. The median has only 50% of the cases below it ONLY in a normal distribution.
15-1.3
[tex]15 - 1.3 = [/tex]
Answer:
13.7
Step-by-step explanation:
Rewrite 15 - 1.3 as 15.0 - 1.3.
Then rewrite this result as
15.0

Is a centimeter more or less then a meter
Answer:
A meter is 100 times larger than a centimeter
Step-by-step explanation:
A meter is larger than a cm. u can try it on a ruler. look at the cm notice how it is smaller than a meter.
Answer:
It depends.
Step-by-step explanation:
I won't say centimeter is less or more than a meter, because 1 meter is equal to 100 center centimeter. But when you compare different measurement it can, for example:
2 m = 200 cm (Both are same)
3 m > 250 cm (m is greater, actually 3m = 300 cm)
4 m < 450 cm (cm is greater, 4 m = 400 cm)

I have no clue!
Answer:
18
Step-by-step explanation:
Honestly you can just use a calculator for this.
But if you want to know how to actually do it, multiplying something by a fraction is just dividing it by its reciprocal (just flipping the numerator and the denominator).
Therefore...
72/4 is 18, 72 x 1/4 = 18
Answer:
without a calculator u can solve by divideing 72 by 4

Mr. Finch buys a pack of ground coffee. He uses the same amount of ground coffee for each cup of coffee he brews. The equation below describes the relationship between the number of cups brewed (x) and the ounces of coffee (y) remaining in the pack.
How much ground coffee, in ounces, was in the full pack?
A: 3
B: 6
C:15
D:18
I think it was C:15 but I am not exactly sure
The equation that relates the number of cups brewed to the ounces of coffee remaining is necessary to determine the initial amount of coffee in the pack, which is not provided in the question.
Explanation:The question does not provide the specific equation that describes the relationship between the number of cups brewed (x) and the ounces of coffee (y) remaining in the pack. However, the task is to determine how much ground coffee, in ounces, was in the full pack when Mr. Finch purchased it. To solve this, we would typically need to know how much coffee is used per cup and have an initial amount representing the full pack. If the equation was provided, we could use it to calculate the initial amount of the coffee. Without the equation, we cannot proceed with the calculation. Ensuring all critical information is provided in a word problem is crucial for solving it.

Find the sum of the even numbers shown below. 2+4+6+8+...+66+68+70
The sum its +2
2+2=4
4+2=6
6+2=8
8+2=10
And so on the numbers just keep sum for 2
Final answer:
To find the sum of even numbers from 2 to 70, we use the arithmetic sequence sum formula, resulting in a total sum of 1260.
Explanation:
The student's question is asking to find the sum of even numbers from 2 to 70. To do this, we can recognize that this is an arithmetic sequence, where the first term (a1) is 2, the last term (an) is 70, and the common difference (d) is 2, as we are stepping through even numbers only. This sequence has (70/2) terms, which gives us 35 terms.
The sum of an arithmetic sequence is given by the formula S = n/2 (a1 + an), where S is the sum, n is the number of terms, a1 is the first term, and an is the last term. By applying this formula, we can calculate the sum as follows: S = 35/2 (2 + 70) = 35 (72/2) = 35 (36) = 1260.
Therefore, the sum of the even numbers from 2 to 70 is 1260.

Which of the following options have the same value as 25% of 64?
Choose 2 answers:
A) 25 • 64
B) 25/100 • 64
C) .25 • 64
D) 64 divided by 25/100
E) 25 divided by 64/100
Answer:
A) 25 • 64
B) 25/100 • 64
C) .25 • 64
D) 64 divided by 25/100
E) 25 divided by 64/100
B and C i believe
The values that have the same value as 25% of 64 are Options B) 25/100 · 64 and C) .25 · 64, both yielding the correct value of 16 when calculated.
Explanation:To find the same value as 25% of 64, we need to express 25% in different formats and apply it to 64. Option B) 25/100 · 64 translates the percent into a fraction, then multiplies by 64. Option C) .25 · 64 converts the percentage directly into a decimal, again multiplying by 64. Both expressions will yield the same result, which is the value of 25% of 64.
Options A), D), and E) do not give the correct value. A) is simply multiplication without considering the percentage, D) is incorrect because dividing 64 by a fraction is equivalent to multiplying by its reciprocal, and E) is an incorrect fraction division that does not represent 25% of 64.
Therefore, the correct answers are B) and C).

B-p=pw
Divide each side by p
(B-p) /p = pw/p
(B-p) /p = w
B/p -1 =w
Jack is mowing lawns. He mows lawns at a constant rate of 1/3 acre every 3/4 hour. At this rate, which fraction represents the acres Jack can mow per hour?
Answer:
1/4 acre every 1 hour
Step-by-step explanation:
divide 1/3 with 3/4 to find unit rate
Answer:
[tex]\frac{4}{9}acres/hr[/tex]
Step-by-step explanation:
Givens
The constant rate is 1/3 acre per every 3/4 hour.To find the fraction that represents the constant per hour, we just need to divide both expression, like this
[tex]\frac{1}{3}acre \div \frac{3}{4}hr=\frac{1}{3}\times \frac{4}{3} =\frac{4}{9}acres/hr[/tex]
Therefore, the expression that represents the acres Jack can mow per hour is
[tex]\frac{4}{9}acres/hr[/tex]

How much money will you have if you started with $1250 and put it in an account that earned 6.7% every year for 14 years?
Answer:
$3098.93
Step-by-step explanation:
We can use the formula for compound growth to solve this. The formula is:
[tex]F=P(1+r)^t[/tex]
Where
F is the future value (the value at end of 14 years, our answer)
P is the initial amount invested ($1250)
r is the interest rate, in decimal (6.7% is 0.067)
t is the time in years (14, in our case)
Plugging in all the information we have:
[tex]F=P(1+r)^t\\F=1250(1+0.067)^14\\F=1250(1.067)^14\\F=3098.93[/tex]
The account will accrue $3098.93 after 14 years.
event q is more likely to occur then event t. the probability of event t is 1/2. what is a possible probability of event q?
Among the given options, option C) 2/3 is a possible probability for event Q that is greater than 1/2. Therefore, the correct answer is C) 2/3.
If event Q is more likely to occur than event T and the probability of event T is 1/2, then a possible probability of event Q could be any value greater than 1/2.
Let's dive deeper into the concept of probability and explore why option C) 2/3 is a possible probability for event Q.
When we say that event Q is more likely to occur than event T, it means that the probability of event Q is greater than the probability of event T. In this case, we are given that the probability of event T is 1/2.
To find a possible probability for event Q, select a value greater than 1/2. Option C) 2/3 fits this criterion. It indicates that event Q has a probability of 2/3, which is greater than 1/2.
Complete question
Event Q is more likely to occur than Event T. If P(Event T) = 1/2, what is a possible probability of Event Q? A)1/4 B)1/2 C)2/3 D)It cannot be determined.
The possible probability of event q is is [tex]\(\frac{3}{4}\).[/tex]
Since event Q is more likely than event T, the probability of event Q must be greater than the probability of event T.
The probability of event T is [tex]\(\frac{1}{2}\),[/tex] so the probability of event Q must be greater than [tex]\(\frac{1}{2}\).[/tex]
This satisfies the condition that event Q is more likely than event T because [tex]\(\frac{3}{4}\) (or 0.75)[/tex] is greater than [tex]\(\frac{1}{2}\) (or 0.5).[/tex]
It is important to note that there are infinitely many probabilities that are greater than [tex]\(\frac{1}{2}\)[/tex] and less than or equal to 1 (the maximum probability for any event).
However, the question asks for a possible probability, and [tex]\(\frac{3}{4}\) is[/tex] a valid example that meets the given criteria.
Is this True or False ?
Answer:
Option B True
Step-by-step explanation:
we know that
A function relates each element of a set (input) with exactly one element of another set (output)
1) "...each element..." means that every element in X (input) is related to some element in Y (output)
2) "...exactly one..." means that a function is single valued. It will not give back 2 or more results for the same input
therefore
f(x) is a function

Which are solutions to 3sin^2 θ - 2sin θ = 0, 90°≤θ≤90°
Answer:
The solutions of the equation are -41.8° , 0.0° , 41.8°
Step-by-step explanation:
∵ 3 sin²Ф - 2 sinФ = 0 is a quadratic function
∵ The domain of the function is -90° ≤ Ф ≤ 90°
- Lets take sinФ as a common factor
∴ sinФ (3 sinФ - 2) = 0
- Two terms multiplied by each other = 0
∴ One of them must be equal zero
∴ sinФ = 0 or 3 sinФ - 2 = 0
- If sinФ = 0 ⇒ Ф = 0.0°
- If 3 sinФ - 2 = 0 ⇒ 3 sinФ = 2 ⇒ sin Ф = 2/3
∵ sinФ 2/3
∴ Ф = 41.8° ⇒ Ф ≤ 90° (in first quadrant)
∵ -90° ≤ Ф ≤ 90°
∴ Ф = -41.8° ⇒ Ф ≥ -90° (in fourth quadrant)
∴ The solutions of the equation are -41.8° , 0.0° , 41.8°
Step-by-step explanation:
Correct Answer is B and C 0.0, and 41.8
