Captain Ben has a ship, the H.M.S Crimson Lynx. The ship is four furlongs from the dread pirate Umaima and her merciless band of thieves.
If his ship hasn't already been hit, Captain Ben has probability \dfrac{3}{4}

start fraction, 3, divided by, 4, end fraction of hitting the pirate ship. If his ship has been hit, Captain Ben will always miss.
If her ship hasn't already been hit, dread pirate Umaima has probability \dfrac{1}{2}
2
1
start fraction, 1, divided by, 2, end fraction of hitting the Captain's ship. If her ship has been hit, dread pirate Umaima will always miss.
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?
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.

A class of 27 students had a mean of 83 on a math quiz. The 12 girls in the class had a mean of 80.5 on the quiz. What was the mean of the boys’ scores?
a. 77
b. 77.5
c. 85
d. 85.5
Answer:
D
Step-by-step explanation:
It would most likely have to be above 83 to bring the average down, so A and B are out. It would most likely be D, since it would equally be 5 between 80.5 and 85.5 to get an even 83.

Ruchi had 2 1/2 litres of milk. She used 1/2 litre for curd, 3/5 litre for tea, 1/4 litre for coffee, and the remaining she gave to her children in the breakfast. How much milk was used by the children for breakfast?
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]
The remaining volume used by the children is [tex]\frac{23}{20}[/tex]

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
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

in this diagram/picture, which equation could you prove to be true in order to conclude that the lines are parallel?
Answer Choices:
A)
[tex] \frac{c - a}{b} \times \frac{d}{e } = - 1[/tex]
B)
[tex] \frac{c - a}{b} \times \frac{ - d}{e} = - 1[/tex]
C)
[tex] \frac{c - a}{b} = \frac{ - d}{e} [/tex]
D)
[tex] \frac{c - a}{b} = \frac{d}{e} [/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.

7. The graph of part of linear function g is shown on the grid. Which inequality best represents the domain of the part shown?
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.

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.

0/4 06 Fill in the Blank Text The ratio of the number of people who own a smartphone to the number of people who own a flip phone is 6:4. If 200 more people own a smartphone than a flip phone, how many people own each type of phone?
9514 1404 393
Answer:
smart phone: 600flip phone: 400Step-by-step explanation:
The difference in ratio units is 6-4 = 2, which corresponds to 200 people. So, each ratio unit corresponds to 200/2 = 100 people. Then the ratio 6 : 4 corresponds to 600 : 400 = smart : flip owners.
The number of phone owners is ...
600 smart phone
400 flip phone
If a man earns $805 per week, in how many days he will earn $1,840?
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 the distance between the points (13,19) and (13,-14)
Answer:
[tex]d = 33[/tex]
Step-by-step explanation:
Distance Formula: [tex]d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Simply plug in the 2 coordinates into the distance formula to find distance d:
[tex]d = \sqrt{(13-13)^2+(-14-19)^2}[/tex]
[tex]d = \sqrt{(0)^2+(-33)^2}[/tex]
[tex]d = \sqrt{(-33)^2}[/tex]
[tex]d = 33[/tex]
Answer:
the distance between the two points is 33 units.
Step-by-step explanation:
because the two points have the same x value, we only need to consider the y values.
find the difference to solve for the distance.
[tex]19-(-14)\\19+14\\33[/tex]
the answer is 33 units.
