a parking lot can hold cars and small trucks. the scatter plot shows how many cars and trucks parked at the parking lot each day for a week. What is the daily average number of trucks at the lot that week? round to the bearest tenth if neccessary.
Answers
the answer to your question that is above is 3.3
Answer:
Daily average number of trucks at the lot that week are 3.3
Step-by-step explanation:
Given a parking lot which can hold cars and small trucks. The scatter plot show parking lot each day for a week in the given graph. We have to find the daily average number of trucks at the lot that week.
In order to find the daily average we have to add the no. of trucks park daily in a week the take the average dividing by 7.
No. of trucks park in a parking lot day-by-day in week are
2, 3, 3, 4, 6, 2, 3
We take the average as
[tex]\frac{2+3+3+4+6+2+3}{7}=\frac{23}{7}=3.28\sim3.3[/tex]
Hence, daily average number of trucks at the lot that week are 3.3

The perimeter, P, of a rectangle is the sum of twice the length and twice the width.
P = 2(l+w) units
P = 2(5)+2(9) units
P = 4x units
P = (l+l)+(w+w) units
P = 2(x+3) units
Answers
This is because when you let the perimeter of the rectangle be P, the length of the rectangle be l and the width of the rectangle be w.
The information above can be expressed as the following equation,
P = 2l + 2w
You can then factorise out the common factor, 2.
P = 2(l+w)
Thus, the answer is P = 2(l+w) units.
Answer:
P=2(l+w)
Step-by-step explanation:
It is given that perimeter, P, of a rectangle is the sum of twice the length and twice the width.
Let length of rectangle is l and width of the rectangle is w.
Perimeter = 2 × Length + 2 × Width
[tex]P=2\times l+2\times w[/tex]
[tex]P=2l+2w[/tex]
Taking out common factors.
[tex]P=2(l+w)[/tex]
[Note: (l+l)+(w+w) units is also true but according to the statement only option 1 is true]
Therefore, the correct option is 1.
the population pf a city is 2,500. if the number of males is 240 more than the number of females how many males and females are there in the city
Answers
You need to represent the number of males in terms of females.
Explanation:Since you know the number of males relative to females, it makes sense to represent the number of females as a variable, let's say f.
So then the number of males is f+240 and we know that the number of males plus the number of females is 2500. Knowing this, we can write an equation: f+(f+240)=2500. I put the number of males in brackets there just to make it easy to recognize.
This equation can be condensed into 2f+240=2500 and then solved:
2f=2500−240
f=2500−2402
f=1130
Then, we know the number of females, and we can solve for the number of males from here using our male formula: males=f+240. You should then get 1370 as the number of males.
Checking this answer, we see that 1130 + 1370 does equal 2500.

If p(a|b) = 0.35, p(b) = 0.75 and p(a) = 0.44 are the events a and b independent ?
Answers
Final answer:
Two events A and B are considered independent if the probability of A given B (P(A|B)) is equal to the probability of A, and the probability of B given A (P(B|A)) is equal to the probability of B. In this case, events a and b are not independent.
Explanation:
Two events A and B are considered independent if the probability of A given B (P(A|B)) is equal to the probability of A, and the probability of B given A (P(B|A)) is equal to the probability of B.
In this case, if p(a|b) = 0.35, p(b) = 0.75, and p(a) = 0.44, we can determine if events a and b are independent by comparing the given probabilities.
To check if events a and b are independent, we need to find p(a|b) and compare it to p(a), and find p(b|a) and compare it to p(b).
p(a|b) = 0.35 means that the probability of event a occurring given that event b has occurred is 0.35. Since p(a|b) is not equal to p(a), events a and b are not independent.

Hence, we will see at which point the graph of:
[tex]y=-x^2+4x[/tex]

Suppose that water is stored in a cylindrical tank of radius 5 m. if the height of the water in the tank is h, then the volume of the water is v = Ïr 2h = (25m2)Ïh = 25Ïh m2. if we drain the water at a rate of 250 liters per minute, what is the rate at which the water level inside the tank drops?
Answers
To calculate the rate at which the water level drops, use the formula dh/dt = dV/dt / (25Ï) and the given drainage rate of 250 liters per minute. The resulting rate is -0.01/Ï meters per minute, which represents the speed of the water level decreasing.
Explanation:To determine the rate at which the water level inside the cylindrical tank drops, we use the given volume formula of the cylinder, V = 25Ï h, where V is volume in cubic meters, h is height in meters, and Ï is the constant pi (approximately 3.14159).
Draining the tank at a rate of 250 liters per minute corresponds to a volume rate of 0.25 cubic meters per minute (since 1 cubic meter equals 1000 liters). Using the formula dV/dt = 25Ï dh/dt, we want to find the rate dh/dt at which the height of the water decreases.
Rearranging for dh/dt gives us dh/dt = dV/dt / (25Ï). Substituting the known rate of volume change, dV/dt = -0.25 m³/min (negative because the volume is decreasing), we get dh/dt = -0.25 / (25Ï), which simplifies to dh/dt = -0.01 / Ï meters per minute. Therefore, the rate at which the water level drops is -0.01/Ï meters per minute.

Determine the amount of an investment if 5000 is invested at an interest rate of 4.5% compounded monthly for 10 years. Round your answer to the nearest whole dollar
Answers
The amount of an investment of $5,000 at an interest rate of 4.5% compounded monthly for 10 years will be $7,847, rounded to the nearest whole dollar.
Explanation:To determine the amount of an investment that starts at $5,000, with an interest rate of 4.5% compounded monthly for 10 years, we use the formula for compound interest:
A = P(1 + r/n)^(nt)
Where:
A is the amount of money accumulated after n years, including interest.P is the principal amount (the initial amount of money).r is the annual interest rate (decimal).n is the number of times that interest is compounded per unit t.t is the time the money is invested for in years.Plugging the values into the formula:
A = 5000(1 + 0.045/12)^(12*10)
A = 5000(1 + 0.00375)^(120)
A = 5000(1.00375)^(120)
A = 5000 * 1.569463137
A = $7,847 (rounded to the nearest whole dollar)
The amount of the investment after 10 years, compounded monthly at 4.5% interest, will be $7,847.
A company is creating a box without a top from a piece of cardboard, but cutting out square corners with side length x.

Answers
----------------------------------------------------
----------------------------------------------------
The original width is 10 inches. The width reduces to 10-2x inches after we cut off the top two corners of the rectangle. We can think of it as taking 10 and subtracting off two copies of x like so: 10-x-x = 10-2x
Similarly, the length goes from 30 inches to 30-2x inches. This time we're taking off the top and bottom corners (focus on either side it doesn't matter).
The height of the box is x inches due to this portion being folded up.
Volume of box = (width)*(length)*(height)
Volume of box = (10-2x)(30-2x)x
Note: the units for the answer are in cubic inches which can be written as "in^3" (inches cubed).

Given:
6 consecutive integers are x − 2, x − 1, x, x + 1, x + 2, x + 3
