the sum of two numbers is 526, and their difference is 176. find the two numbers
Answers
Answer:
Step-by-step explanation:
We can write the information as equations. We will use variables x and y to find the two numbers
Equation 1: The sum of two numbers is 526
x + y = 526
Equation 2: The difference is 176
x - y = 176
With two variables and two equations, we can first find one variable by elimination:
(See image)
and then substitute y into either equation to find x:

Find the midpoint between the pair of points using the Midpoint
Formula. *
(7,-2) and (-4, 2)
Answers
Given parameters:
Coordinates = (7,-2) and (-4, 2)
The formula for the coordinate of the mid point is;
[tex]x_{m}, y_{m}[/tex] = ( [tex]\frac{x_{1} + x_{2} }{2} , \frac{y_{1} + y_{2} }{2}[/tex] )
where;
[tex]x_{m}, y_{m}[/tex] are the coordinates of the mid points
x₁ = 7 y₁ = -2
x₂ = -4 y₂ = 2
Input the parameters and solve;
[tex]x_{m}, y_{m} = \frac{7 + (-4)}{2} , \frac{-2 + 2}{2}[/tex]
[tex]x_{m}, y_{m}[/tex] = [tex]\frac{3}{2} , 0[/tex]
So the mid point is at [tex]\frac{3}{2} , 0[/tex]

D)

Answers
Answer:
b/a=c/d Two lines are parallel to each other if they have the same slope. So let's look at the options and see which one matches that statement. b/aâ‹…c/d=â’1 * This is checking to see if the two lines are perpendicular to each other. Almost the exact opposite of parallel. So this is the wrong answer. b/a=c/d * b/a is a legitimate slope. c/d is also a good slope. And they're being checked to see if they're equal to each other. So this is the correct answer. But let's see if the next two options will give us a chuckle or two. b/a=d/c * b/a is OK. d/c almost looks ok, check the figure. And d/c is NOT a slope. The slope is delta Y over delta X. And d/c is delta X over delta Y. The inverse of the slope. So comparing those two values is meaningless. So it's a wrong answer. b/aâ‹…d/c=â’1 * And they're trying the inverse of the slope trick again. WRONG. And they're checking if it's perpendicular. Also wrong. So definitely not a good choice.

if k-9=5(k-3)find k
Answers
Answer:
K = 3/2
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
k−9=5(k−3)
k+−9=(5)(k)+(5)(−3)(Distribute)
k+−9=5k+−15
k−9=5k−15
Step 2: Subtract 5k from both sides.
k−9−5k=5k−15−5k
−4k−9=−15
Step 3: Add 9 to both sides.
−4k−9+9=−15+9
−4k=−6
Step 4: Divide both sides by -4.
-4k/-4 = -6/-4
K = 3/2

If the Captain and the pirate each shoot once, and the pirate shoots first, what is the probability that both the pirate and the Captain hit each other's ships?
Answers
Answer:
0
Step-by-step explanation:
We are told that if the Captain's ship has been hit, he will always miss and since the pirate is shooting first, the captain's ship could be hit. So the probability that both of them hit each other's ship is 0 because if the pirate hits the Captain's ship, he will always miss. 1/2 * 0 = 0
There is no way for both of them to hit each other's ships because if their ships have been hit, they will always miss.

7. The graph of part of linear function g is shown on the grid. Which inequality best represents the domain of the part shown?
Answers
Answer:
a
Step-by-step explanation:
Domain means the change in x.
so the domain will be which values of x the fn goes through.
you can see the black line goes from -9 to 2 in x values.
the -9 isn't filled in, but the 2 is. filled in means it will be with an equals instead of without.
so x is between -9 and 2, 2 is with equals -9 is without,
so the first one.
The inequality best represents the domain of the part shown should be -9<x ≤2.
What is domain?Here domain means the change in the x. Here the domain should be the values of with respect to fn. Also, here we have to watch the blank line that goes from -9 to 2 in x values.
Since 9 should not be filled however 2 should be.
hence, The inequality best represents the domain of the part shown should be -9<x ≤2.

Find an equation of the line with slope m that passes through the given point. Put the answer in slope -intercept form.
(5, 3), m=-3/4
Answers
Answer:
y = -3/4x + 6.75
Step-by-step explanation:
Slope intercept form is y = mx + b, where m is the slope and b is the y intercept.
Plug in the given point and slope into the equation, then solve for b:
y = mx + b
3 = -3/4(5) + b
3 = -3.75 + b
6.75 = b
Then, plug in the slope and y intercept into the equation:
y = -3/4x + 6.75 is the equation of the line in slope intercept form

Matched pairs t test is used for paired data. Data sets are "paired" when the two sets have the same number of data points and each data point in a set is related to only one data point in the other set.
A good example is before/after data. Each set has the same number of data points, and each data point in the after set is related to one in the before set.
B is not an option because, although the samples are the same size, there is not a paired relationship between the sets.
C is not an option because the samples are not the same size.
