Answer:
The length of the midsegment is 9 ⇒ (B)
Step-by-step explanation:
In a triangle,
The midsegment is the segment which joining the midpoints of two opposite sides of itThe length of the midsegment is half the length of the third side in the triangle which opposite to itLet us use this rule to solve our question
In Δ AC
∵ DE is the midsegment of it
∵ DE is opposite to the side AC
∴ The length of DE = 1/2 the length of AC
∵ The length of AC = 18
∴ The length of DE = 1/2 × 18
∴ The length of DE = 9
∴ The length of the midsegment is 9
The correct answer is B

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.

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

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.

Answers
Answer: 1 15/100
Step-by-step explanation: 2 1/2- 1/2 = 2 - 3/4 = 1 3/4 - 3/5 = 1 15/100
Given parameters:
Total volume of milk Ruchi has = [tex]2\frac{1}{2}[/tex] liters
Amount used for curd = [tex]\frac{1}{2}[/tex] liters
Amount used for tea = [tex]\frac{3}{5}[/tex] liters
Amount used for coffee = [tex]\frac{1}{4}[/tex] liters
Unknown:
Quantity of milk used by the children for break fast = ?
Since this quantity is the remaining volume;
Remaining volume = Total volume - (Amount used for curd + amount used for tea + amount used for coffee)
Remaining volume = [tex]\frac{5}{2} - (\frac{1}{2} + \frac{3}{5} + \frac{1}{4} )[/tex]
Remaining volume = [tex]\frac{23}{20}[/tex]

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 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.

If a man earns $805 per week, in how many days he will earn $1,840?
Answers
Answer:
15.99 or rounded to 16 days
Step-by-step explanation:
1,840 divided by 805 = 2.28
2.28 times 7 = 15.99
Step-by-step explanation:
There are seven days in one week. To find out how much money this man earns in ONE day, you can divide $805 by 7 days like so:
$805 / 7 days = $115 per day
To find out how many days it takes for the man to earn $1,840, you must divide $1,840 by $115 to get the number of days like so:
$1,840 / 115$ = 16 days
Therefore, the man earns $1,840 in 16 days.

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
