The absolute value of -19, expressed as |-19|, is +19. That of |+17| is 17. We are thus left with +19 - 17, or 2.
Whats The Answer And the Steps to Get the answer
The answer is 1 7/8. I got this by first looking at the two negatives. Negative times a negative is always a positive.So if you would write this expression again it would look like: -3 1/4 + 5 1/8
Now you find the common denominator which is 8. Convert -3 1/4 to have a denominator of 8: -3 2/8
Now you can convert both of those fractions into improper fractions: -26/8+41/8
Compute: 15/8
You can either leave your answer like that or you can change it into a mixed fraction :
1 7/8

meaning of mean medium and mode
The Mean is the value of all the numbers in a data set added together and divided by the amount of numbers there are for example the mean of the set 2,5,8,9 is 6.
The median is the middle values of all the numbers. If there are 2 medians, you usually have to add them both and divide by 2 to get the actual median
The mode is the number(s) that show up the most in the data set. for example, the mode of the data set 2,2,3,4,4,4,6,9 is 4, because it is repeated 3 times.

In a student opinion poll at Jump Middle School 27.5% of the students who responded chose football as their favorite sport. Basketball was chosen by 17.5% of the students who responded. The rest of the people chose “other” sports. “Other” sports were chosen by 44 people in the poll. What is the total number of the people who responded to the poll?
Answer-
The total number of the 80 students responded to the poll.
Solution-
The percentage of student who responded that football was their favorite sport = 27.5%
The percentage of student who responded that basketball was their favorite sport = 17.5%
As the remaining students opted for others, so the percentage of student who opted other sport = 100-(27.5+17.5) = 100-45 = 55%
The number of student who chose others, was found to be 44. If total number of student participated in the opinion poll was x, then
[tex]\Rightarrow x \times\frac{55}{100} =44[/tex]
[tex]\Rightarrow x=44 \times\frac{100}{55}=80[/tex]
∴ The total number of the people who responded to the poll was 80.

we know that
A quadratic function written in standard form is
[tex]y=ax^{2} +bx+c[/tex]
in this problem we have
[tex]y=2x^{2} +5x-1[/tex]
so
[tex]a=2\\b=5\\c=-1[/tex]
Final answer:
The function y = -2x² + 5x - 1 is written in standard form, which for a quadratic function is ax² + bx + c.
Explanation:
The function given is y = -2x² + 5x - 1. This function is written in standard form, which is characterized by the quadratic term, followed by the linear term, and then the constant term. The general form of a quadratic function is ax² + bx + c, where a, b, and c are constants, and in this case, a is -2, b is 5, and c is -1.

Elaine had m dollars in her checking account. On December 8, she deposited $1,200, r dollars, and $568.90. She also cashed a check for t dollars and one for $73.70. Write an algebraic expression that represents the amount of money in her account after the transactions.
Initial amount in Elaine's account = m dollars ---- (1)
On December 8, total money deposited by Elaine = 1200 + r + 568.9
= r + 1768.9 ----- (2)
Total money on her account now = m + r + 1768.9
Total money she cashed by cheques = t + 73.7.
Therefore, her current balance in her account = (m + r + 1768.9) - (t + 73.7)
= (m + r - t) + 1695.2.
Hence, the algebraic expression that represents the amount of money in her account after the transactions is (m + r - t) + 1695.2.
Final answer:
Elaine's checking account balance after her transactions is represented by the algebraic expression m + 1200 + r + 568.90 - t - 73.70, with m being her initial balance, r the amount deposited, and t the amount from the check that was cashed.
Explanation:
Elaine had m dollars in her checking account. After various transactions, we can represent the amount of money in her account with an algebraic expression. The transactions include deposits and cashed checks. The deposits add money to her account, while cashing checks subtract money from her account.
To calculate the new balance, the following expression can be used:
New Balance = original balance + sum of deposits - sum of cashed checks
In Elaine's case, her initial balance is m dollars. She deposited $1,200, r dollars, and $568.90, which are added to her account. She also cashed checks for t dollars and for $73.70, which are subtracted from her account. Therefore, the algebraic expression representing the new account balance after these transactions would be:
m + 1200 + r + 568.90 - t - 73.70

3. Edward tells Tom and his brother that any two different gym memberships will eventually have a month in which they are the same cost. So he believes any gym's membership will eventually have a month in which the cost is the same as Platinum Gym's. Describe a membership situation that will make Edward's statement untrue.
Answer:
Remember that: "Platinum Gym charges a one-time registration fee of $60, and membership is $20 a month."
We are solving for a membership that will make Edward's statement untrue, that the gym membership fee will NOT have a month where the cost is the same.
For example, I can say that:
" Bob's Gym charges a one-time registration fee of $50, and membership is $10 a month ".
In this case, the pricing is much lower than Platinum Gym's and would not have a chance of getting the same cost in the same month.
Another example can be:
" SuperSneaker's charges a one-time registration fee of $100, and membership is $30. "
Again, the cost is much more higher than Platinum Gym's and would not have a chance of getting the same cost in the same month.

what is the slope intercept form for 2x+8y=32
the slope is 1/4
and the y intercept is -4
Hope this helps
Answer:
y = -1/4x +4
Step-by-step explanation:
Slope intercept form of a line will have y on the left and mx+c on the right.
y = mx+c
Here m is the slope and c is the intercept
Any form of line can be brought to slope intercept form
Given that 2x+8y =32
We have to keep y along on left side
Hence subtract 2x first
8y =-2x+32
Now divide by 8
y = -1/4x +4 is the equation in slope intercept form

What are the coordinates for the center of the circle and the length of the radius ?
the answer to your question is D
Answer: the correct option is
(D) (-7, -1), 6 units.
Step-by-step explanation: We are given to find the co-ordinates of the center and the length of the radius of the following circle :
[tex]x^2+y^2+14x+2y+14=0~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)[/tex]
We know that
the STANDARD equation of a circle with center at the point (h, k) and radius of length r units is given by
[tex](x-h)^2+(y-k)^2=r^2.[/tex]
From equation (i), we have
[tex]x^2+y^2+14x+2y+14=0\\\\\Rightarrow (x^2+14x+49)+(y^2+2y+1)+14-49-1=0\\\\\Rightarrow (x+7)^2+(y+1)^2-36=0\\\\\Rightarrow (x+7)^2+(y+1)^2=36\\\\\Rightarrow (x-(-7))^2+(y-(-1))^2=6^2.[/tex]
Comparing the above equation with the standard equation of a circle, we get
center, (h, k) = (-7, -1) and radius, r = 6 units.
Thus, (D) is the correct option.
How many integers n leave remainder 4 when divided by 7, if n satisfies the given inequality?
|−n|<46
PLEASE SHOW YOUR WORK
The integer n can take any value between -45 and 45, satisfying the given inequality |−n| < 46 and leaving a remainder of 4 when divided by 7.
Explanation:An integer n leaves a remainder of 4 when divided by 7 if it satisfies the given inequality |−n| < 46.
To find the possible values of n, we can solve the inequality.
|-n| < 46 → -n < 46 and -n > -46 → 46 > n > -46.
Therefore, n can take any integer value between -45 and 45, with the condition that it leaves a remainder of 4 when divided by 7.

The cube root of 50 is between which two integers.
The two integers between which the cube root of 50 lies are 3 and 4.
To find the two integers between which the cube root of 50 lies, we can start by evaluating the cube roots of consecutive integers until we find the two integers that enclose the cube root of 50.
Let's calculate the cube roots of some consecutive integers:
Cube root of 1: 1
Cube root of 2: 1.25992
Cube root of 3: 1.44225
Cube root of 4: 1.58740
Cube root of 5: 1.70997
Cube root of 6: 1.81712
Cube root of 7: 1.91293
Cube root of 8: 2
Cube root of 9: 2.08008
Cube root of 10: 2.15443
We can observe that the cube root of 50 is greater than the cube root of 27 (which is approximately 3), and less than the cube root of 64 (which is 4). Therefore, the cube root of 50 lies between 3 and 4.
Hence, the two integers between which the cube root of 50 lies are 3 and 4.

Point B has coordinates (5,2). The x-coordinate of point A is negative 7. The distance between point A and point B is 13 units. What are the possible coordinates of point A?
Final answer:
To find the possible coordinates of point A with a known x-coordinate of -7 and a distance of 13 units from point B (5, 2), we used the distance formula and found two possible y-coordinates for point A, which are -3 and 7. Hence, the possible coordinates for point A are (-7, -3) and (-7, 7).
Explanation:
The question asks for the possible coordinates of point A given that point B has coordinates (5, 2), the x-coordinate of point A is -7, and the distance between points A and B is 13 units. To find the y-coordinate of point A, we can use the distance formula d = √((x2 - x1)^2 + (y2 - y1)^2). Substituting the known values, we have:
13 = √((5 - (-7))^2 + (2 - y1)^2)
Squaring both sides of the equation, we get:
169 = (12)^2 + (2 - y1)^2
This simplifies to:
169 = 144 + (2 - y1)^2
Subtract 144 from both sides:
25 = (2 - y1)^2
Now, taking the square root of both sides, we get two possible solutions for the y-coordinate:
y1 = 2 ± 5
Thus, the possible y-coordinates of point A are -3 and 7. Therefore, the possible coordinates for point A are (-7, -3) and (-7, 7).
you roll a six sided die three times. what is the size of the sample space after those three rolls?
The answer is 216 because we will compute 6^3 = 6*6*6 = 36*6 = 216
If we had 2 dice rolled out, then it would be 6^2 = 6*6 = 36. For each die added, we multiply another 6 because the die has 6 sides.
Visually, 2 dice form a 2D table of 36 possible outcomes. Three dice form a 3D cube of possible outcomes (a 6 by 6 by 6 cube with volume 216). You can think of it like a rubix cube. Each sub-block would house a possible combo such as {2,1,7} meaning that you rolled a '2' on the first die, a '1' on the second die, and a '7' on the third die.
Note: rolling a single die 3 times will produce the same sample space as rolling three separate dice 1 time.
216 is the answer to it
