Consequently, the solution of the given question of probability comes out to be P(x<5.67 = 0.63
What is probability?Probability fundamentals. A probability is a number that expresses the possibility or likelihood that a specific event will take place. Probabilities can be stated as proportions with a range of 0 to 1, or as percentages with a range of 0% to 100%.
Here,
we use the z-score algorithm to answer this query.
Score Z = x - 40/5
x = the raw score
population mean= μ
Population standard deviation is σ
Hence,
x = 40 μ = 5.67, σ =5
Z = 5.67 - 40/5
z=0.37
Probability based on the Z-Table:
P(x<5.67 = 0.63
Consequently, the solution of the given question of probability comes out to be P(x<5.67 = 0.63 .

Equilateral triangle T is inscribed in circle A , which has radius 10 . Circle B with radius 3 is internally tangent to circle A at one vertex of T . Circles C and D , both with radius 2, are internally tangent to circle A at the other two vertices of T. Circles B, C , and D are all externally tangent to circle E, which has radius m/n , where m and nare relatively prime positive integers. Find m+n
For the given figure, where m and nare relatively prime positive integers. The value of m+n is 32.
Explain Law of Cosines.The law of cosines, also known as the law of cosines, relates all three sides of a triangle to one angle of the triangle. Most useful for searching for missing information in triangles. For example, if you know all three sides of a triangle, you can use the law of cosines to find the measure of the angle. Similarly, if you know two sides and the angle between them, you can find the length of the third side by the law of cosines.
Let X be the intersection of the circles with centers B and E, and Y be the intersection of the circles with centers C and E.
Since the radius of B is 3, AX = 4.
Assume AE = p.
Then EX and EY are radii of circle E and have length 4 + p.
AC = 8, and ∠CAE = 60° because we are given that triangle T is equilateral.
Using the Law of Cosines on Δ CAE, we obtain
(6+p)² =p² + 64 - 2(8)(p) cos 60
The 2 and the cos 60 terms cancel out:
p² + 12p + 36 = p² + 64 - 8p
12p+ 36 = 64 - 8p
p = 28/20
= 7/5
The radius of circle E is 4 + (7/5)
= 27/5,
So, the answer is 27 + 5 = 32

The student is partially correct as -5 is less than -4 but ln |-5| is not less than ln |-4|.
What is reasoning?
We can ascertain the veracity of the supplied propositions using mathematical reasoning, often known as the mathematical reasoning principle.
A student said that -5 is less than -4.
This statement is correct and the reasoning is -
According to the number line, 0 is the midpoint.
From 0 to the right side of infinity the digits increases.
So, 1 is bigger than 0, 2 is bigger than 1, 3 is bigger than 2, and so on.
Similarly, from 0 to the left side of negative infinity the digits decreases.
So, -1 is smaller than 0, -2 is smaller than -1, -3 is smaller than -2, and so on.
The student also said that ln |-5| is less than ln |-4|.
This statement is false and the reasoning is -
First simplify ln |-5| and ln |-4| -
ln |-5| = ln (5)
ln (5) = 1.6094
ln |-4| = ln (4)
ln (4) = ln (2^2)
ln (2^2) = 2 ln (2)
2 ln (2) = 1.3862

Provide an answer accurate to the nearest tenth of a foot.
The height of the Building is 110.01 feet.
What is the Pythagorean theorem?The square of the hypotenuse side in a right-angled triangle is equal to the sum of the squares of the other two sides, according to Pythagoras' Theorem.
Given, Finn leaned a 100-foot ladder against the side of a building. The base of the ladder is 14 feet from the base of the building. The top of the ladder is 11 feet from the top of the building.
For the triangle made by ladder
hypotenuse = 100
base = 14
thus, from the Pythagorean theorem
hypotenuse² = base² + height²
100² = 14² + height²
height² = 10000 - 196
height = √9804
height = 99.01
total height of the wall = height of triangle + remaining height of the wall
Thus the total height of the wall = 99.01 + 11
the total height of the wall = 110.01
therefore, the building is 110.01 feet tall.

a) Bearing from A to B is 253°.
b) Bearing from B to A is 287°.
What is a bearing?
A bearing is an angle measured clockwise from north in mathematics. Typically, bearings are expressed as a three-figure bearing.
a)
The bearing of 73° and the co-interior angle formed must total 180°. The counter-clockwise angle from B to A is 107°.
However a bearing must always be measured clockwise from north. 107° is counter-clockwise from north.
The clockwise angle on the other side is needed. Use the angle fact that angles in a full turn add to 360°.
To work the bearing, subtract 107° from 360°.
360° – 107° = 253° and so, the bearing of A from B is 253°.
b)
The bearing of 107° and the co-interior angle formed must total 180°. The counter-clockwise angle from A to B is 73°.
However a bearing must always be measured clockwise from north. 73° is counter-clockwise from north.
The clockwise angle on the other side is needed. Use the angle fact that angles in a full turn add to 360°.
To work the bearing, subtract 73° from 360°.

Please Simplify the phrase the first two and find the last one
Answer:
1) 23x + 6y
2) 8x - 4y
3) 4x - x² + 7
Step-by-step explanation:
Simplify:
Multiply each term of (3x + 6y) by 5 and multiply each term of (2x - 6y) by 4.
5(3x + 6y) + 4 (2x - 6y) = 5*3x + 5*6y + 4*2x - 4*6y
= 15x + 30y + 8x - 24y
Now, combine like terms. Like terms have same variable with same power.
= 15x + 8x + 30y - 24y
= 23x + 6y
2) 3(4x - 2y) - 2*(2x -y) = 3*4x + 3*(-2y) + (-2)* 2x + (-2)*(-y)
= 12x - 6y - 4x + 2y
= 12x - 4x - 6y + 2y
= 8x - 4y
3) f(x) = 3x + 2
To find f(x +1), replace x with (x +1)
f(x +1) = 3*(x + 1) + 2
= 3*x + 3*1 + 2
= 3x + 3 + 2
=3x + 5
f(2x) = 3*(2x) + 2
= 6x + 2
f(2x) + h(x) = 6x + 2 - x² - 2x + 5
= 6x - 2x - x² +2 + 5

10. Jim estimates the width of his wall to be 7.5 feet. The actual wall measures 8.25 feet wide. What is
Jim's percent error?
Answer:
Below
Step-by-step explanation:
Error : (8.25 - 7.5)
% error : ( 8.25-7.5) / 8.25 * 100% = 9.1 %
Jim's percent error is 9.09%.
What is the percentage error?
The percentage error is given as the difference between the actual value and the estimated value divided by the actual value, multiplied by 100%.
The percentage error is a relative value that compares the actual value and the estimated value to explain any deviations.
Estimated width of wall = 7.5 feet
The actual width of the wall = 8.25 feet
The difference in estimate = (8.25 - 7.5) = 0.75 feet
Percentage Error = (0.75/8.25 x 100) = 9.09%
Thus, we can conclude that Jim made a percentage error of 9.09% in his estimate of the width of the wall.
How I find a area of triangle when 3 equation of sides are given?
The area of a triangle when three side lengths are calculated by Heron's Formula. Heron's Formula states that the area of a triangle is equal to the square root of s(s-a)(s-b)(s-c)
To calculate the area of a triangle when three side lengths are given, we can use Heron's Formula. Heron's Formula states that the area of a triangle is equal to the square root of s(s-a)(s-b)(s-c) where s is half the perimeter of the triangle and a, b, and c are the lengths of the sides of the triangle.
To calculate the area of the triangle given three side lengths, we first need to calculate the perimeter (p) of the triangle. The formula for the perimeter is p=a+b+c.
Then, use this formula to calculate s, which is half the perimeter.
s = p/2
Once s is calculated, plug it into Heron's Formula to calculate the area of the triangle.
Area = √s(s-a)(s-b)(s-c)

John invests $25,000 in an account that pays 4.75% annual interest compounded continuously. How many years, to the nearest tenth, will it take for John’s investment to triple?
Answer:
The equation you would use to solve this problem is:
A = P * e^(rt)
Where A is the final amount, P is the initial amount, r is the interest rate, and t is the number of years.
We can rearrange the equation to solve for t:
t = (ln(A/P)) / r
Plugging in the values we know:
t = (ln(3*25000/25000)) / (0.0475)
t = (ln(3)) / (0.0475)
t = 4.93 years
So it will take about 4.9 years for John's investment to triple, to the nearest tenth.
