if I have around 9 5-day weeks or 65 days to complete 116 assignments how many assignments do I do for every 5 day week, every day, even tell me how many to do every month
Answer:
You have:
9 weeks ⇒ 116 assignments ⇔ 116/9 ≈ 13 a week9*5= 45 days ⇒ 116 assignments ⇔ 116/45 ≈ 2.6 a day2.25 months ⇒ 116 assignments ⇔ 116/2.25 ≈ 52 a monthIf you consider working weekends as well:
9*7 = 63 days ⇒ 116 assignments ⇔ 116/63 ≈ 2 a dayFor assignments to do for every 5-day week :
9 weeks = 116 assignments
∴ For every week = 116/9 = 13 assignments
________________________________
For assignments to do for every day :
9 weeks = 116 assignments
We have 5 days in 1 week
∴ 9 weeks = 9 × 5 = 45 days
∴ For every day = 116/45 = 3 assignments (approx.)
________________________________
For assignments to do for every month :
1 month = about 30 days
∴ 65 days = 2 months 5 days = 2.2 months (approx.)
∴ For every month = 116/2.2 = 52 assignments (approx.)

Laura buys an unfair coin online. The coin is supposed to land heads up 75% of the time. If this is true, what is the
probability that in 20 flips, the first 15 land heads up and the last 5 land tails up?
Answer:
C . (0.75) 15 x (0.25) 5
Step-by-step explanation:
Took the assignment in edge, it’s right
Its based off of the rule P(A and B) = P(A) x P(B) from multiplication rule for independent events.
The probability that in 20 flips, the first 15 land heads up and the last 5 land tails up is 0.000390625.
What is probability?Probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.
If the coin is supposed to land heads up 75% of the time, then the probability of getting heads on a single flip is 0.75 and the probability of getting tails is 0.25.
To find the probability that in 20 flips, the first 15 land heads up and the last 5 land tails up, you can use the formula for the probability of independent events:
P(A and B) = P(A) × P(B)
where A and B are independent events, and P(A) and P(B) are the probabilities of events A and B occurring, respectively.
In this case, the probability of the first 15 flips landing heads up is P(A) = 0.75¹⁵, and the probability of the last 5 flips landing tails up is P(B) = 0.25⁵.
Therefore, the probability that in 20 flips, the first 15 land heads up and the last 5 land tails up is:
P(A and B) = P(A) × P(B) = (0.75¹⁵) × (0.25⁵) = 0.000390625

Step-by-step explanation:
what is the point-slope form of the equation for the line with a slope of -2 that passes through the point (4,-6)
Answer:
[tex]y + 6 = -2 (x-4)[/tex]
Step-by-step explanation:
Point-slope formula is represented by the equation [tex]y-y_1 = m (x-x_1)[/tex]. When knowing a point a line crosses through and its slope, you can write an equation in this form. Substitute the [tex]m[/tex], [tex]x_1[/tex], and [tex]y_1[/tex] for real values.
The [tex]m[/tex] represents the slope of the line. Since we know the slope is -2, substitute -2 for [tex]m[/tex]. The [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of the point the line passes through. Since the line passes through (4, -6), substitute 4 for [tex]x_1[/tex] and -6 for [tex]y_1[/tex]. This gives the following answer and equation:
[tex]y-(-6) = -2 (x - (4))\\y + 6 = -2 (x-4)[/tex]
Answer:
y=-2x+2
Step-by-step explanation:
y-y1=m(x-x1)
y-(-6)=-2(x-4)
y+6=-2(x-4)
y=-2x+8-6
y=-2x+2
A plane with the tailwind is 500 km/h. While going against the wind it is 410 km/h. What is the speed of the plane without wind?
Answer:
45
Step-by-step explanation:
Let the plane speed be x
Let the wind speed be y
x +y= 500.....equation 1
x -y= 410........equation 2
x + y= 500
-
x- y= 410
2x= 90
x= 90/2
x= 45
From equation 1, substitute 45 for x
x + y= 500
45 + y= 500
y = 500-45
x = 455
Hence the speed of the plane is 45

In a group of 100 politicians, 40 are in Party I and 60 are in Party II. Members of Party I are incapable of changing their minds about anything. Members of Party II change their minds completely randomly every day, independently of all others and also independently of all evidence. Tomorrow, the politicians are going to vote on Proposition 88. Here is a summary of their opinions today. Of the 40 members in Party I, 25 are in favor of Prop 88 and 15 are against. Of the 60 members in Party II, 10 are in favor and 50 are against. Assume that each member in Party II changes their mind based on the toss of a coin: if it lands heads they switch to the opposite opinion and if it lands tails they don't change their mind.
What is the distribution of the number of members in Party II who will favor Prop 88 tomorrow?
Answer:
30 members.
Step-by-step explanation:
Given that in a group of 100 politicians, 40 are in Party I and 60 are in Party II, and that the members of the latter Party change their minds completely randomly every day, independently of all others and also independently of all evidence, knowing that of the 60 members in Party II, 10 are in favor and 50 are against Proposition 88 and that each member in Party II changes their mind based on the toss of a coin: if it lands heads they switch to the opposite opinion and if it lands tails they don't change their mind, to determine the distribution of the number of members in Party II who will favor Prop 88 the following logical reasoning must be performed:
In every coin toss there is a 50% chance that it will come up heads, and a 50% chance that it will come up dry. Thus, we could affirm that each member of Party II has a 50% chance of changing their vote, that is, that an estimated half of the members will change their position. Thus, knowing that initially 10 are in favor and 50 are against Proposition 88, in case half changes their position, the 10 in favor would become 5 in favor and 5 against, and the 50 against would become 25 for and 25 against. In this way, some 30 members of Party II will favor Prop 88.
a circle has a radius of 2x inches. if the radius is multiplied by a factor of 3/8. what is the new area of the circle
Answer:
(PI x 3/4x square) inches
Step-by-step explanation:
A of a circle = pi times radius squared
A = pi times 3/4x - that is 2x times 3/8
A = 3.14 (or whatever you use for pi) x 3/4 x inches square

what is difference between point and dot
Answer:
A dot is a physical object, not a mathematical object. A dot has a size and is roughly circular, but the size is not defined. It’s a fuzzy concept; how big does it have to be before it’s no longer a dot but a blot? An how irregular can a dot be?
A point is a mathematical object in geometry. It has a position but no size. It has no definition because none of the basic objects of mathematics has a definition. The axioms of geometry give relationships between and properties of undefined terms such as point, line and plane.
