What type of line is PQ¯¯¯¯¯¯¯¯?
A. altitude
B. median
C. side bisector
D. angle bisector
The line PQ is altitude of the triangle. This can be obtained by understanding what an altitude is.
What is altitude of a triangle?Altitude of a triangle: the perpendicular drawn from the vertex of the triangle to the opposite side.Commonly known as height of the triangle.Properties of altitude of a triangle:
A triangle has 3 altitudes from the three vertices of the triangle.The 3 altitudes intersect at a point known as the orthocenter of the triangleThe altitude of the triangle is the shortest distance from the vertex to the opposite side.In the given triangle,
it is clear that angle Q is 90° and therefore PQ is a perpendicular line from the point P.
Since the perpendicular line, which is PQ, is drawn from the vertex, which is P of the triangle to the opposite side, which is SR.
Thus PQ is the altitude of the triangle.
Hence in the given figure, the line PQ is the altitude of the triangle.

10 workers can finish the job in 15 days. For the first 5 days, only 6 workers worked on the job. Then for the next 3 days 2 more workers joined them. To finish the job, 4 more workers joined
them. After how many days was the whole job done?
A. 8days
B. 12days
C. 16days
D. 18days
Answer:
C. 16 days
Step-by-step explanation:
Let´s say each worker does 1 ¨work¨, for each day, in order to complete the job in 15 days. That´s a total of 150 work.
If only 6 workers worked for the first 5 days, then we only do 30 by Day 5.
2 more workers join, so they do 8 work each day, 24 work in 3 days, 54 work by Day 8.
4 more workers join to complete the job, so we now do 12 work each day.
150 - 54 = 96
96 work is left to do, which would be done in 8 days by 12 workers.
8 days + 8 days = 16 days
In a mid-size company, the distribution of the number of phone calls answered each day by each of the 12 receptionists is bell-shaped and has a mean of 46 and a standard deviation of 5. Using the empirical rule, what is the approximate percentage of daily phone calls numbering between 36 and 56?
The approximate percentage of daily phone calls numbering between 36 and 56 by the receptionists is 95.44%.
In a mid-size company, the distribution of the number of phone calls answered each day by each of the 12 receptionists is bell-shaped and has a mean of 46 and a standard deviation of 5.
Hence, Mean,μ=46 and Standard deviation,σ=5.
To find the probability of daily phone calls numbering between 36 and 56,
P(36≤X≤56)
To convert the X score to Z score, use the formula, Z=(X-μ)/σ
Then we get,
P((36-46)/5 ≤ Z ≤ (56-46)/5) = P(-2 ≤ Z ≤ 2)
By using the property of the normal bell curve, we get
P(-2 ≤ Z ≤ 2) = P(2 ≤ Z) - P(-2 ≤ Z)
As per the normal distribution table,
P(2 ≤ Z) - P(-2 ≤ Z) = 0.9772-0.0228
∴ P(36≤X≤56) = 0.9544
Hence, the approximate percentage of daily phone calls numbering between 36 and 56 by the receptionists is 95.44%.

(x, y) = (r · cos t, r · sin t), where t is in radians.
If we assume that r = 1, then we proceed to determine the location of the seven points remaining:
(x₁, y₁) = (cos π/2, sin π/2)
(x₁, y₁) = (0, 1)
(x₂, y₂) = (cos 3π/4, sin 3π/4)
(x₂, y₂) = (- √2 /2, √2 /2)
(x₃, y₃) = (cos π, sin π)
(x₃, y₃) = (- 1, 0)
(x₄, y₄) = (cos 5π/4, sin 5π/4)
(x₄, y₄) = (- √2 /2, - √2 /2)

29) Selecting a blue marble, a white marble, and then a red marble.
O a.) 4/19
Ob.) 4/91
Oc.) 3/19
Od.) 7/91
Answer:
4/91
Step-by-step explanation:
There are a total of 15 marbles. In the first selection there are 15 marbles and 6 are blue. That would be 6/15.
Since we are not replacing marbles, we now have 14 marbles and we want to select one of the 5 white marbles. That would be 5/14.
Lastly we now only have 13 marbles and of those we want to select one of the 4 red ones. That would be 4/13.
Now we take these 3 fractions and multiply them together.
6/15(5/14)(4/13). I am going to try to make this a little easier and see if I can find any factors that any top number shares with any bottom number.
I see 5 on the top shares a common factor with 15 on the bottom. I will divide these numbers by 3, so now I have
6/3(1/14)(4/14). I think that I can do better than that. I see that 6 on the top and 3 on the bottom share a common factor of 3. I will divide both of these numbers by 3. Which will give me:
2/1(1/14)(4/13) I see a 4 on top and a 14 on the bottom. Those are both divisible by 2 so, I will divided them both by 2 and that leaves me with
2/1(1/7)(2/13) That is a lot easier, now I will just multiple the top numbers and multiply the bottom numbers to get
4/91
Evaluate:
(3,251)(30)
Answer: 97350
Step-by-step explanation:
The numbers (3251)(30) are separated by using parentheses by multiplying the numbers we get 97350.
What is multiplication?
When we notice two or more numbers together that exist divided by parentheses, then the parentheses exist pointing us to multiply. In math, multiplying indicates adding equivalent groups. When we multiply, the number of things in the group rises. The two elements and the product exist as regions of a multiplication problem.
Given: (3251)(30)
Here, the numbers are separated by using parentheses, then the parentheses exist pointing us to multiply.
Therefore, by multiplying the numbers we get
(3,251)(30) = 97350
Therefore, the correct answer is 97350.

The equation of the line of best fit using the slope-intercept formula y=mx+b is y = x - 5
Equation of the line of best fitA line is the shortest distance between two points. The equation in point-slope form is expressed as:
y =. mx + b
m is the slope
b is the y intercept
Using the coordinate points (25, 20) and (60, 55)
Slope = 55-20/60-25
Slope = 35/35
Slope = 1
For the intercept
20 = 1(25) + b
b = 20 - 25
b = -5

y = x + (-5)
y = x - 5

The solution of the differential equation y(3)=29/9.
Given a differential equation y'+(y/x)=x for y(1)=1.
A differential equation is an equation that contains at least one derivative of an unknown function, either a normal differential equation or a partial differential equation.
We will solve this differential equation by using the integrating factor method.
Firstly, we will find the integrating factors by using the formula, we get
[tex]I.F=e^{\int Pdx}[/tex]
Here P=1/x and substitute this in the formula, we get
[tex]\begin{aligned}I.F.&=e^{\int \frac{1}{x}dx}\\ &=e^{\log x}\\ &=x\end[/tex]
Now, we will substitute the values in the formula
[tex]y\times I.F.=\int Q\times I.F.dx[/tex]
Here Q=x an substitute this in the above formula, we get
[tex]\begin{aligned}y\times x&=\int x\times xdx\\ yx&=\int x^{2} dx\\ yx&=\frac{x^3}{3}+C\end[/tex]
Further, we will divide both sides with x, we get
y=(x²/3)+(C/x) ......(1)
Given that y(1)=1 means when x=1 then y=1 so substitute this in equation (1) to find the value of C, we get
1=(1/3)+C
1-(1/3)=C
2/3=C
Substitute the value of C in equation (1), we get
y=(x²/3)+(2/(3x))
Now find the value of y when x=3, we get
y=(9/3)+(2/9)
y=3+(2/9)
y=29/9
Hence, in the differential equation y'+(y/x)=x for y(1)=1 then y(3) is 29/9.
