A company has two offices - one in Portlee and one in Queentown.
The ratio of the number of employees at Portlee to the number at Queentown is 3:4
20% of the employees at Portlee are part-time.
25% of the employees at Queentown are part-time.
Altogether the company has 32 part-time employees.
Work out the total number of employees the company has.
The company has the total number of employees as 140.
What is the ratio?It is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.
We are given that company has two offices - one in Portlee and one in Queentown.
The ratio of the number of employees at Portlee to the number at Queentown is given as;
3:4
Now we know that 20% of the employees at Portlee are part-time.
25% of the employees at Queentown are part-time.
Therefore, 3x of 20% are part- time
4x of 25%
Then we have 32 part-time employees.
0.6x + 1x = 32
1.6x = 32
x = 32/1.6
x = 20
Hence, the total number of employees the company has
3x + 4x = 7x
7(20) = 140

Solve the given initial-value problem. Give the largest interval I over which the solution is defined.
L di/dt +Ri =E, i(0)=i0 L, R, E, i0 constants
The solution to the given IVP is.[tex]$i(t)-\frac{E}{R}+\left(i_0-\frac{E}{R}\right) e^{-\frac{R}{L}}$[/tex]
Initial value problems describe a type of problem in calculus. Initial value problems in calculus concern differential equations with a known initial condition that specifies the value of the function at some point. The purpose of these problems is to find the function that describes the system, which can be done by integrating the differential equation.
Consider the initial value problem,
L [tex]\frac{d i}{d t}+R i=E \text {. }[/tex]
The initial condition is. [tex]$i(0)=i_0$[/tex]
Rewrite the DE as,
[tex]\begin{gathered}L \frac{d i}{d t}+R i=E \\\frac{d i}{d t}+\frac{R}{L} i=\frac{E}{L}\end{gathered}$$[/tex]
This is a linear DE.
Compare the DE [tex]\frac{d i}{d t}+\frac{R}{L} i=\frac{E}{L}$[/tex] with the general DE [tex]\frac{d i}{d t}+P(t) i=Q(t)$[/tex]. Then [tex]$P(t)=\frac{R}{L}$[/tex] and [tex]$Q(t)=\frac{E}{L}$[/tex].
Find the integrating factor (IF).
[tex]$$\begin{aligned}I F & =e^{\int P(t) \vec{t}} \\& =e^{\int\left(\frac{\pi}{\mathrm{I}}\right) \mathrm{A}} \\& =e^{\frac{\pi}{l^2}}\end{aligned}$$[/tex]
Thus, the integrating factor is [tex]$I F=e^{\frac{R^2}{2^2}}$[/tex].
Now multiply both sides of the DE with the IF.
[tex]$$\begin{array}{r}e^{\frac{R}{\bar{L}^t}}\left(\frac{d i}{d t}+\frac{R}{L} i\right)=\frac{E}{L} e^{\frac{R}{L^t}} \\\frac{d i}{d t} e^{\frac{\pi}{L^t}}+\frac{R}{L} e^{\frac{R}{\bar{L}^t}} i=\frac{E}{L} e^{\frac{\pi}{\bar{L}^t}} \\{\left[i e^{\frac{R}{L^2}}\right]=\frac{E}{L} e^{\frac{R^L}{L^t}}}\end{array}$$[/tex]
Integrate on both sides.
[tex]$$\begin{aligned}& \int\left[i e^{\frac{R}{L}}\right] d t=\int \frac{E}{L} e^{\frac{R}{L^t}} d t \\& i e^{\frac{R}{L^{\mathrm{r}}}}=\frac{E}{L} \int e^{\frac{\pi}{L^t}} d t \\& i e^{\frac{R}{\perp} r}=\frac{E}{L}\left[\frac{e^{\frac{R}{2}}}{\frac{R}{L}}\right]+C \\& i e^{\frac{R}{\Gamma}+}=\frac{E}{R} e^{\frac{R^2}{I^{+}}}+C \\& i(t)=\frac{\frac{E}{R} e^{\frac{R}{L^2}}+C}{e^{\frac{R}{D^2}}} \\& t(t)=\frac{E}{R}+C e^{-\frac{R}{L^t}} \\&\end{aligned}$$[/tex]
Thus, the general solution to the [tex]\mathrm{DE}[/tex] is [tex]$i(t)=\frac{E}{R}+C e^{-\frac{R}{t^*}}$[/tex].
Use the initial condition. [tex]$i(0)=i_0$[/tex]
Substitute [tex]$t=0$[/tex] and [tex]$i(0)=i_0$[/tex] in [tex]$i(t)=\frac{E}{R}+C e^{-\frac{R}{I^t}}$[/tex].
[tex]$$\begin{aligned}& i(0)=\frac{E}{R}+C e^{-\frac{R}{I}(0)} \\& i_0=\frac{E}{R}+C e^0 \\& i_0=\frac{E}{R}+C \quad \text { use } e^0=1 \\& C=i_0-\frac{E}{R}\end{aligned}$$[/tex]
Substitute [tex]$C=i_0-\frac{E}{R}$[/tex] in [tex]$i(t)=\frac{E}{R}+C e^{-\frac{R}{L^1}}$[/tex].
[tex]$$\begin{aligned}& i(t)=\frac{E}{R}+C e^{-\frac{R}{I}} \\& i(t)=\frac{E}{R}+\left(i_0-\frac{E}{R}\right) e^{-\frac{\pi}{t^t}}\end{aligned}$$[/tex]
Therefore, the solution to the given IVP is. [tex]$i(t)-\frac{E}{R}+\left(i_0-\frac{E}{R}\right) e^{-\frac{R}{L}}$[/tex].

The p-value of 0.017 suggests that there is a statistically significant difference in the proportion of high school seniors who own their own cars, indicating that more high schoolers now have cars than before.
The p-value of 0.017 indicates that there is a statistically significant difference between the proportion of high school seniors who own their own cars today compared to a decade ago. This suggests that there is a real, measurable difference in the number of high school seniors who own cars, meaning that it is reasonable to conclude that more high schoolers have cars now than they did a decade ago. This conclusion is supported by the statistical significance of the data, which indicates that the difference between the proportions is not likely due to chance. It is also likely that changes in technology and access to transportation options have contributed to the increase in the proportion of high school seniors who own cars.

iq scores have a mean of 100 and standard deviation of 16. sat scores have a mean of 1000 with a standard deviation of 100. which is probably less likely, randomly meeting someone whose IQ is under 80 or someone who obtained a SAT score of over 1150
It is less likely to randomly meet someone who obtained a SAT score of over 1150.
What is Z score?Z score or standard score is defined as the number of standard deviations by which the observed value is above or below the mean value.
The formula for calculating z score is,
z = (x - μ) / σ
where x is the observed value, μ is the population mean and σ is the population standard deviation.
For IQ scores,
z = (80 - 100) / 16 = -1.25
For SAT scores,
z = (1150 - 1000) / 100 = 150/100 = 1.5
z score is closer to 0 for IQ scores and far to 0 for SAT scores.
Hence it is less likely to meet someone who obtained a SAT score of over 1150.

A car is rolling south at 8 miles per hour, and a man pushes the car north at 10 miles per hour. What is the resultant vector on the car
The resultant vector on the car would be a vector pointing north with a magnitude of 2 miles per hour.
The resultant vector is the net effect of two or more individual vectors on an object. It is the overall force or movement that is produced when all the individual vectors are combined. To find the resultant vector, you would add together all of the individual vectors using vector addition. The resultant vector would be represented by a single vector with a certain magnitude and direction.
If a car is rolling south at 8 miles per hour, and a man pushes the car north at 10 miles per hour, subtract the southward velocity from the northward velocity.
10 mph northward - 8 mph southward= 2 mph northward

Using the velocity of 64 meters per second, we know that the air pressure is 910 millibars.
What is air pressure?Everything you touch is pressed upon by the weighty air that surrounds you.
This pressure is referred to as air pressure or atmospheric pressure.
It is the force that the air above a surface applies to it while gravity pulls the surface toward Earth.
A barometer is frequently used to measure atmospheric pressure.
So, we know that:

64 M/s is the average sustained wind speed.
The equation for mean sustained wind speed:
v = 6.3√1013 - p
Hurricane's means sustained wind speed is 64 m/s,
With the help of the following equation, we can determine the air pressure.
v = 6.3√1013 - p
64/6.3 = √1013 - p
Making both sides square:
(10.1587)² = 1013 - p

Does a triangle have 3 equal angles?
Yes, a triangle can have three equal angles. The term "equilateral triangle" is used to describe this.
A 60-degree equilateral triangle has the same length for all three angles. This is due to the fact that all three angles in a triangle have to add up to 180 degrees, and when three angles are equal, the sum is divided equally between them.
An equiangular triangle is another name for an equilateral triangle. An equilateral triangle takes on the form of an equilateral triangle because all of its sides are equally angled. The term "congruent" refers to the fact that all three sides of the triangle are the same length.
Numerous mathematical disciplines, including geometry and trigonometry, make use of equilateral triangles. They are often used to show how other shapes, like parallelograms and rhombi, work. Additionally, they are utilized in the process of determining the perimeter, angles, and area of a triangle.

The average value of f(x) = 8x sec^2(x) on the interval [0, π/4] is -4/3.
To find the average value of a function f(x) on an interval [a, b], we need to evaluate the definite integral of the function over that interval and divide it by the length of the interval.
The definite integral of f(x) = 8x sec^2(x) over the interval [0, π/4] is given by:
∫[0,π/4] 8x sec^2(x) dx
This integral can be evaluated by substitution. Let u = sec(x) and du = sec(x)tan(x)dxmthen the integral becomes:
∫[0,π/4] 8x sec^2(x) dx = ∫[1,sec(π/4)] 8xu^2du
= 8/3u^3 evaluated at u = sec(π/4) - 8/3u^3 evaluated at u = 1
= 8/3sec^3(π/4) - 8/3 = 8/3(1/cos^3(π/4)) - 8/3 = 8/3*(1/1/2) - 8/3 = 4/3 - 8/3 = -4/3
