A density curve for all the possible ages between 0 years and 50 years is in the shape of a triangle. What is the height of the triangle? O A. 0.04 O B. 0.02 O c. 0.01 O D. 0.08 SUBMIT
Answer:
0.04
Step-by-step explanation:
For a density curve, total area = 1
Probability lies in between 0 and 1
The Area of triangle :
Area = 1/2 base * height
Base = 0 - 50 = 50
Area = 1
Hence,
1 = 1/2 * 50 * h
1 = 50h / 2
2 = 50h
h = 2 / 50
h = 0.04

Answer:
sqrt = square root of
Cosecant of 0 = (sqrt 41) / 5
Cos of 0 = 4/(sqrt41)
Tan of 0 = 5/4
Step-by-step explanation:
In this case, the opposite is 5, the adjacent is 4 and the hypotenuse is C in 5^2+4^2 = C^2 (pythagorean theorem)
5^2 = 25, 4^2 = 16
25+16 = 41
sqrt 41 is the hypotenuse
cosecant is hypotenuse/opposite
cos is adjacent/hypotenuse
and

What is the difference in unit price between a 5 gallon bucket of paint for $97.45 and a 1 gallon bucket of paint for $21.95?
Answer: $2.46
Step-by-step explanation:
First, let's find the unit price for both buckets!
A 1 gallon bucket of paint is $21.95. But how much will a 1 gallon bucket of paint cost if it had origianlly been 97.45 for 5 gallons of paint?
We need to divide 97.45 by 5, and the answer will be the unit price.
97.45 ÷ 5 = 19.49.
A 1 gallon bucket of paint that was originally priced as $97.45 for 5 gallons of paint si now $19.49 per bucket.
But we're not done! We still need to find the difference in unit prince between a 5 gallon bucket of paint for $97.45 and a 1 gallon bucket of paint for $21.95.
21.95 - 19.49 = 2.46.
Therefore, the difference in unit price between a 5 gallon bucket of paint for $97.45 and a 1 gallon bucket of paint for $21.95 is $2.46.

An unconditional acceptance into a graduate program at a university will be given to students whose GMAT score plus 100 times the undergraduate grade point average is at least 1075. Robbin's GMAT score was 800. What must her grade point average be in order to be unconditionally accepted into the program?
Robbin's grade point average must be at least ___ in order to be unconditionally accepted into the program.
Answer:
Robbin's grade point average must be at least 2.75 in order to be unconditionally accepted into the program.
Step-by-step explanation:
An unconditional acceptance into a graduate program at a university will be given to students whose GMAT score plus 100 times the undergraduate grade point average is at least 1075.
This means that:
[tex]x + 100y \geq 1075[/tex]
In which x is the GMAT score and y is the GPA.
Robbin's GMAT score was 800.
This means that [tex]x = 800[/tex]
What must her grade point average be in order to be unconditionally accepted into the program?
We have to solve the inequality for y. So
[tex]x + 100y \geq 1075[/tex]
[tex]800 + 100y \geq 1075[/tex]
[tex]100y \geq 275[/tex]
[tex]y \geq \frac{275}{100}[/tex]
[tex]y \geq 2.75[/tex]
Robbin's grade point average must be at least 2.75 in order to be unconditionally accepted into the program.

9514 1404 393
Answer:
9 units
Step-by-step explanation:
The graph shows a vertical line at x = -1, with points at y=-4 and y=5. The distance between the points is the difference of their y-coordinates:
5 -(-4) = 5+4 = 9
You can count the grid squares between the points, if you like.
The distance between the points is 9 units.

What are derivatives?A technique for determining a function's derivative is differentiation. Mathematicians use a procedure called differentiation to determine a function's instantaneous rate of change based on one of its variables. The most prevalent illustration is the velocity or rate of change of displacement with respect to time.
We know, The tangent sum identity is tan(x + y).
We also know that tan(x + y) = (tanx + tany)/(1 - tanxtany).
Now, tan = sin.cos.
Therefore,
(tanx + tany)/(1 - tanxtany).
= [(sinx/cosx) + (siny/cosy)/(cosxcosy/cosxcosy) - (sinxsiny/cosxcosy)].
= sin(x + y)/cos(x + y).

The cost of a week long vacation in a city has a mean of 1000 and a variance of 1200. The city imposes a tax which will raise all tourism related costs by 10%. Find the coefficient of variation for the cost of a week long vacation in this city after the tax is imposed.
Answer:
The coefficient of variation after the tax is imposed is 0.033
Step-by-step explanation:
Given
[tex]\mu =1000[/tex] --- mean
[tex]\sigma^2 = 1200[/tex] --- variance
[tex]tax = 10\%[/tex]
Required
The coefficient of variation
The coefficient of variation is calculated using:
[tex]CV = \frac{\sqrt{\sigma^2}}{\mu}[/tex]
After the tax, the new mean is:
[tex]\mu_{new} = \mu * (1 + tax)[/tex]
[tex]\mu_{new} = 1000 * (1 + 10\%)[/tex]
[tex]\mu_{new} = 1100[/tex]
And the new variance is:
[tex]\sigma^2_{new} = \sigma^2 * (1 + tax)[/tex]
[tex]\sigma^2_{new} = 1200 * (1 + 10\%)[/tex]
[tex]\sigma^2_{new} = 1320[/tex]
So, we have:
[tex]CV = \frac{\sqrt{\sigma^2}}{\mu}[/tex]
[tex]CV = \frac{\sqrt{1320}}{1100}[/tex]
[tex]CV = \frac{36.33}{1100}[/tex]
[tex]CV = 0.033[/tex]

i need help with this question on my geometry homework
Answer:
x = 250°
Step-by-step explanation:
Inscribed angle = ½(intercepted arc measure) (inscribed angles theorem)
x is intercepted arc measure
125° is the inscribed angle
Therefore:
125° = ½(x)
Multiply both sides by 2
2*125° = x
250 = x
x = 250°
what is the value of the x in the given diagram?
Answer:
x = 79
Step-by-step explanation:
All triangles have a sum of 180°. Knowing this, we can solve for the unknown angle.
56 + 23 + ? = 180
79 + ? = 180
? = 101
The variable x is known as an exterior angle. That and the angle we just solved for are supplementary meaning they add up to 180°.
101 + x = 180
x = 79
Answer:
79 degrees
Step-by-step explanation:
56 + 23 = 79
The sum of an arithmetic sequence can be found by the formula Sn = n(2a
+ (n - 1)d). Use the formula to find the sum of first 10 terms of the sequence
{-3.2, 7, 12, 17. 22...)
Step-by-step explanation:
Hey there!
The given series: -3,2,7,12,17,22.....
Common ratio (d) = t2-t1
= 2+3
= 5
No of terms (n) = 10
First term (a) = -3
Now;
[tex]sn = \frac{n}{2} (2a + (n - 1)d)[/tex]
Keeping all values we get;
[tex]s10 = \frac{10}{2} (2 \times - 3 + (10 - 1)5)[/tex]
Simplify it.
[tex]s10 = 5( - 6 + 45)[/tex]
or, S10 = 195.
Therefore, S10 = 195.
Hope it helps!
