We can use sohcahtoa to solve this. First, we know that this triangle is a right triangle, as well as one angle and the opposite side to that angle. We are trying to find the hypotenuse.
Therefore, as sin takes opposite and hypotenuse into account, we can use that to get that sin(41°) = 2.5/x . Multiply both sides by x and divide both sides by sin(41°) to get x = 2.5/sin(41°) =3.8

A certain type of flashlight requires two type-D batteries, and the flashlight will work only if both its batteries have acceptable voltages. Suppose that 90% of all batteries from a certain supplier have acceptable voltages. Among twenty randomly selected flashlights, what is the probability that at least nineteen will work? What assumptions did you make in the course of answering the question posed? a. we have assumed here that the batteries' voltage levels are independent. b. we have assumed here that the batteries' voltage levels are dependent.
Answer:
a) 0.064
b) 0.002
Step-by-step explanation:
a) Assuming that the batteries' voltage levels are independent
Probability = 0.8 * 0.8 = 0.64
b) batteries' voltage levels are dependent
20/19 (0.064)^19 *0.036 + 20/20 (0.064)^20 *0.036^0
= 0.002

relationship between the number of pages, p, that Max can read and the number of
minutes, m?
Answer:
y represents the pages, while x represents the minutes. for every y, there is 9/10 x, therefore the equation is y=9/10x

A rectangle on a coordinate plane is translated 5 units up and 3 units to the left. Which rule describes the translation?
A) (x, y) → (x + 5, y – 3)
B) (x, y) → (x + 5, y + 3)
C) (x, y) → (x – 3, y + 5)
D) (x, y) → (x + 3, y + 5)
Answer:
C
Step-by-step explanation:
Any time you move up or down, it affects the "y" coordinate, and going up is positive so 5 units up is [tex]y + 5[/tex].
Moving left or right affects the "x" coordinate and moving left is negative so
[tex]x - 3[/tex]
[tex](x - 3, y + 5)[/tex]
Hence, C is the correct answer
The mean daily production of a herd of cows is assumed to be normally distributed with a mean of 36 liters, and standard deviation of 7 liters.
A) What is the probability that daily production is less than 23.4 liters? Use technology (not tables) to get your probability.
Answer=
(Round your answer to 4 decimal places.)
B) What is the probability that daily production is more than 45.7 liters? Use technology (not tables) to get your probability.
Answer=
(Round your answer to 4 decimal places.)
Answer:
A) 0.0359
B) 0.0829
Step-by-step explanation:
A) Using normalcdf on your calculator, or using something online, you can plug (-1000, 23.4, 36, 7) to represent the lower bound, upper bound, mean, and standard deviation respectively. The probability that daily production is less than 23.4 liters is 0.0359
B) Similarly, we can plug (45.7, 1000, 36, 7) in as the upper bound is infinity, and the lower bound if 45.7. Our answer is then 0.0829
A Fulcrum of a Pyramid is 6cm Square at the
top and 12cm square at the bottom and is loem highe
Calculate the volume of the fulcrum.
Answer:
288 cubic cm
Step-by-step explanation:
Volume of the pyramid = 1/3 * base area * height
Base area = 12 * 12
Base area - 144 sq. cm
Height = 6cm
Volume of the pyramid = 144 * 6/3
Volume of the pyramid = 144 * 2
Volume of the pyramid = 288 cubic cm

Which is the graph of the function: f(x) = x2 - 4x + 3
Answer:
Option 1
Step-by-step explanation:
To find the graph of the quadratic function, we find it's zeros.
Solving a quadratic equation:
Given a second order polynomial expressed by the following equation:
[tex]ax^{2} + bx + c, a\neq0[/tex].
This polynomial has roots [tex]x_{1}, x_{2}[/tex] such that [tex]ax^{2} + bx + c = a(x - x_{1})*(x - x_{2})[/tex], given by the following formulas:
[tex]x_{1} = \frac{-b + \sqrt{\Delta}}{2*a}[/tex]
[tex]x_{2} = \frac{-b - \sqrt{\Delta}}{2*a}[/tex]
[tex]\Delta = b^{2} - 4ac[/tex]
f(x) = x² - 4x + 3
This means that [tex]a = 1, b = -4, c = 3[/tex]
So
[tex]\Delta = b^{2} - 4ac = (-4)^2 - 4(1)(3) = 16 - 12 = 4[/tex]
[tex]x_{1} = \frac{-(-4) + \sqrt{4}}{2} = 3[/tex]
[tex]x_{2} = \frac{-(-4) - \sqrt{4}}{2} = 1[/tex]

Answer:
Step-by-step explanation:
In a parallelogram, opposite angles are equal.
∠G = ∠E
5x - 9 = 3x + 11
Add 9 to both sides
5x = 3x + 11 + 9
5x = 3x + 20
Subtract 3x from both sides
5x- 3x = 20
2x = 20
Divide both sides by 2
x = 10
∠G = 5x - 9
= 5*10 - 9
= 50 - 9
∠G = 41°
∠G = ∠E = 41°
In parallelogram, adjacent angles are supplementary.
∠G + ∠D = 180
41 + ∠D = 180
∠D = 180 - 41
∠D = 139
∠D = ∠F = 139°
the total mass of 6 rugby players is 540kg and the mean mass of 14 ballet dancers is 40kg. Find the mean mass of the group of 20 rugby players and ballet dancers
Answer:
Mean mass of 20 rugby player = 55
Step-by-step explanation:
Given:
Mass of 6 rugby players = 540 kg
Mean mass of 14 ballet dancer = 40 kg
Find:
Mean mass of 20 rugby player
Computation:
Total mass of ballet dancer = 14 x 40
Total mass of ballet dancer = 560 kg
Total mean mass of 20 rugby player = [540 + 560] / [6 + 14]
Mean mass of 20 rugby player = 1100 / 20
Mean mass of 20 rugby player = 55

Find the equation for the circle with center (-1, - 4) and passing through (-5,5).
Answer:
[tex](x+1)^2+(y+4)^2=97[/tex]
Step-by-step explanation:
Hi there!
Equation of a circle centered at (h,k):
[tex](x-h)^2+(y-k)^2=r^2[/tex] where r is the radius
1) Plug in the center
[tex](x-(-1))^2+(y-(-4))^2=r^2\\(x+1)^2+(y+4)^2=r^2[/tex]
2) Plug in the given point and solve for r²
[tex](x+1)^2+(y+4)^2=r^2[/tex]
Plug in (-5,5)
[tex](-5+1)^2+(5+4)^2=r^2\\(-4)^2+(9)^2=r^2\\16+81=r^2\\r^2=97[/tex]
3) Plug r² back into the equation
[tex](x+1)^2+(y+4)^2=r^2\\(x+1)^2+(y+4)^2=97[/tex]

Answer:
The possible solutions are -4 and -12
Step-by-step explanation:
(C+8)^2=16
Take the square root of each side
sqrt((C+8)^2)=sqrt(16)
C+8 = ±4
C+8 = 4 C+8 = -4
Subtract 8 from each side
C+8-8 = 4-8 C+8-8 = -4-8
C = -4 C = -12
The possible solutions are -4 and -12

Gary went to dinner with his friends. The total bill comes to $135.00 before tax. He wants to leave a 15% tip before tax. He also must pay an 8% tax on the bill. How much does Gary spend in total?
No links or I will report!
Answer:
Gary spends a total of $166.05
Step-by-step explanation:
15% tip: would be 15% of 135, so 0.15 times 135, which would be $20.25 for the tip before tax
8% tax: would be 8% of 135, so 0.08 times 135, which would be $10.8
Then we add $20.25+$10.8+$135= $166.05
Hope I helped, please correct me anywhere you think I may have messed up if I did make mistakes.
Use a linear approximation (or differentials) to estimate the given number. (Round your answer to two decimal places.) (32.03)4/5
Answer:
16.024
Explanation:
Using linear approximation:
We breakdown the numbers in order to solve thus:
[32(1 + 0.1875)]^0.8
= (32^0.8)*(1 + 0.001875)^0.8
= 16* (1 + 0.8*0.001875)
= 16*(1.0015)
= 16.024
The estimated value of the given number is 16.02
What is linear approximation?A linear approximation is an approximation of a general function using a linear function. They are widely used in the method of finite differences to produce first order methods for solving or approximating solutions to equations.
[tex]f(x) = x^{4/5}[/tex] at [tex]x_o = 32\\[/tex] [tex]\Delta\ x = 0.05[/tex]
[tex]f(x) = 32^{4/5} = 16[/tex]
[tex]f'(x) = (4/5)x^{-1/5}\\\\f'(32) = (4/5)32^{-1/5}\\\\= 0.4[/tex]
[tex]L(x) = 0.4(x-32)+16 = x^{4/5}\\\\L(32.05) = 0.4(32.05-32)+16\\\\= 16.02 \\\\= (32.05)^{4/5}[/tex]
Hence, the estimated value of the given number is 16.02
