Answer:
a)
Step-by-step explanation:
he drives every workday of the week 10 miles for work.
that is 5 data every week. so the total miles driven for work during the week is
5×10 = 50 miles.
he can drive with a full tank 100 miles.
so, the remaining miles for the weekend are
100 - 5×10 = 50 miles
A train travels at 100 mph right in equation that compares a time (t) with a distant (d)
Answer:
answer is 2
Step-by-step explanation:
as you know the speed is calculated by dividing the distance travelled by time spent (s=d/t)
so we can write this as d/t=100
when u make d as the subject u get d=100t

3. The carrying capacity of a drain pipe is directly proportional to the area of its cross- section. If a cylindrical drain pipe can carry 36 litres per second, determine the percentage increase in the diameter of the drain pipe necessary to enable it to carry 60 litres per second.
The percentage increase in the diameter of the drain pipe necessary to enable it to carry 60 litres per second is 28.87%.
Given that the carrying capacity is directly proportional to the area, we can write:
C1 ∝ A1 = πr₁²
Since the carrying capacity is directly proportional to the area, we have:
C2 ∝ A2 = πr₂²
To find the percentage increase in diameter, we need to find the ratio of the increased area to the initial area and then express it as a percentage. Let's calculate this ratio:
(A2 - A1) / A1 = (πr₂² - πr₁²) / (πr₁²) = (r₂² - r₁²) / r₁²
We can also express the ratio of the increased carrying capacity to the initial carrying capacity:
(C2 - C1) / C1 = (60 - 36) / 36 = 24 / 36 = 2 / 3
Since the area and the carrying capacity are directly proportional, the ratios should be equal:
(r₂² - r₁²) / r₁² = 2 / 3
Now, let's substitute r = D/2 in the equation:
((D₂/2)² - (D₁/2)²) / (D₁/2)² = 2 / 3
(D₂² - D₁²) / D₁² = 2 / 3
Cross-multiplying:
3(D₂² - D₁²) = 2D₁²
3D₂² - 3D₁² = 2D₁²
3D₂² = 5D₁²
Dividing by D₁²:
3(D₂² / D₁²) = 5
(D₂² / D₁²) = 5 / 3
Taking the square root of both sides:
D₂ / D₁ = √(5/3)
To find the percentage increase in diameter, we subtract 1 from the ratio and express it as a percentage:
Percentage increase = (D₂ / D₁ - 1) × 100
Percentage increase = (√(5/3) - 1) × 100
Percentage increase = 28.87%

Guys, I’m back from nearly a year later went on hiatus on The Brainly because of myself as an anxiety and a very stressful year with A.D.H.D., and I really need help from my own schoolwork from my own school about, “A Perimeter Of The Composite Figures” with only 2 more perimeter questions left to go as soon as possible before it’s too late, please! :O
Please read it as soon as possible before answering to 2 of my own perimeter questions and thank you guys. :)
There’s only 55 points for you to answer to my own 2 of my own perimeter questions, guys! :D
Well good luck, guys! :D
Answer:
2. 26.2 m
3. 117.2 cm
Step-by-step explanation:
You want the perimeters of two figures involving that are a composite of parts of circles and parts of rectangles.
2. Semicircular archThe circumference of a circle is given by ...
C = πd . . . . . where d is the diameter
The length of the semicircle of diameter 12.6 m will be ...
1/2C = 1/2(π)(12.6 m) = 6.3π m ≈ 19.8 m
The two lighted sides of the rectangle have a total length of ...
3.2 m + 3.2 m = 6.4 m
The length of the light string is the sum of these values:
19.8 m + 6.4 m = 26.2 m
The length of the string of lights is about 26.2 meters.
3. Fan shapeThe perimeter of the figure is the sum of four quarter-circles of radius 11.4 cm, and 4 straight edges of length 11.4 cm.
Four quarter-circles total one full circle in length, so we can use the formula for the circumference of a circle:
C = 2πr
C = 2π·(11.4 cm) = 22.8π cm ≈ 71.6 cm
The four straight sides total ...
4 × 11.4 cm = 45.6 cm
The perimeter of the figure is the sum of the lengths of the curved sides and the straight sides:
71.6 cm + 45.6 cm = 117.2 cm
The design has a perimeter of about 117.2 cm.
__
Additional comment
The bottom 12.6 m edge in the figure of problem 2 is part of the perimeter of the shape, but is not included in the length of the light string.

Let X denote the proportion of allotted time that a randomly selected student spends working on a certain aptitude test. Suppose the pdf of X is 0 ≤ x ≤ 1 f(x; 0) (0+1)x 0 otherwise where -1 < 0.
The given pdf is not valid, and it cannot represent a probability distribution.
The given probability density function (pdf) for X is:
f(x; θ) = (0 + 1) * x for 0 ≤ x ≤ 1
0 otherwise
Here, θ represents a parameter in the pdf, and we are given that -1 < θ.
To ensure that the pdf is valid, it needs to satisfy two properties: non-negativity and integration over the entire sample space equal to 1.
First, let's check if the pdf is non-negative. In this case, for 0 ≤ x ≤ 1, the function (0 + 1) * x is always non-negative. And for values outside that range, the function is defined as 0, which is also non-negative. So, the pdf satisfies the non-negativity property.
Next, let's check if the pdf integrates to 1 over the entire sample space. We need to calculate the integral of the pdf from 0 to 1:
∫[0,1] (0 + 1) * x dx
Integrating the function, we get:
[0.5 * x^2] evaluated from 0 to 1
= 0.5 * (1^2) - 0.5 * (0^2)
= 0.5
Since the integral of the pdf over the entire sample space is 0.5, which is not equal to 1, the given pdf is not a valid probability density function. It does not satisfy the requirement of integrating to 1.
Therefore, the given pdf is not valid, and it cannot represent a probability distribution.

Consider what you know about the sampling distribution of the sample proportion. This sampling distribution has a shape that is skewed to the right, regardless of sample size. is a collection of the parameters of all possible samples of a particular size taken from a particular population. Will become more variable as the sample size increases. will have a center equal to the population proportion, orp. Will be Normal in shape only if the sample size is at least 100 .
As per the sampling technique, consider the sampling distribution of the sample proportion. this sampling distribution will have a center equal to the population proportion, or p.
The sampling distribution of the sample proportion. This sampling distribution will become more variable as the sample size increases.
Here for the given question, let us check all the given statements in the options
Here we know that the shape is approximately normal. Then the given option will be false.
Next, it is the collection of all samples taken from the population, So the given option will be false
Standard Deviation
A standard deviation (or σ) is a measure of how dispersed the data is in relation to the mean. Low standard deviation means data are clustered around the mean, and high standard deviation indicates data are more spread out.
Now, the sample size increases, the value of n increases. where n is the value on the denominator of the equation of standard deviation.
Therefore, due to an increase in the value of n, then there will be decreases in the standard deviation.
Then the less standard deviation means a small variance.
Therefore, as a result, as the sample size grows, the variation will be minimal.
So, the center is the same as the sample proportion p.
Therefore, this is correct.

How do I solve this question 5x - [7 - (2x - 1)] = 3(x - 5) + 4(x + 3)
Answer:
x = 6/4, or x = 3/2, OR x = 1 1/2
Step-by-step explanation:
5x - [7 - (2x-1)] = 3(x-5) + 4(x+3)
Pick one side to work on first, I will chose the right side,
Distribute on the right side.
5x - [7 - (2x-1)] = 3x - 15 + 4x + 3
Now, add like terms on the right side.
5x - [7 - (2x-1)] = 7x - 12
Now, to isolate 7 - (2x -1), subtract 5x from both sides.
so now,
-7 - (2x-1) = 2x - 12
Now, we can add 7 to both sides of the equation to isolate -(2x-1)
we add instead of subtract because the seven is a negative.
-(2x-1) = 2x - 5
Now, there is still a negative sign in front of the (2x-1), so we distribute the - to the equation.
-2x + 1 = 2x - 5
Now, we can isolate the variable and numbers bu adding five to both sides, and adding 2 to both sides. This is to make the equation easier by removing any negative terms.
6 = 4x
Divide both sides by 4
x = 6/4, or x = 3/2, OR x = 1 1/2
