Find each angle measure
Answer:
angle 1 = 63°
angle 2 = 117°
angle 3 = 63°
Step-by-step explanation:
angle 2 = 117° (vert.opp.angles)
angle 1 = angle 3 (vert.opp.angles)
angle 1 + angle 2 + angle 3 + 117° = 360°
angle 1 + 117° + angle 3 + 117° = 360°
angle 1 + angle 3 = 360° - 117° - 117°
angle 1 + angle 3 = 126°
angle 1 = 63°
angle 3 = 63°
An article in a magazine discussed the length of time till failure of a particular product. At the end of theâ product's lifetime, the time till failure is modeled using an exponential distribution with a mean of thousand hours. In reliability jargon this is known as theâ "wear-out" distribution for the product. During its normalâ (useful) life, assume theâ product's time till failure is uniformly distributed over the range thousand to million hours. Complete parts a through c.
a. At the end of the productâs lifetime, find the probability that the product fails before 700 thousand hours.
b. During its normal (useful) life, find the probability that the product fails before 700 thousand hours.
c. Show that the probability of the product failing before 830 thousand hours is approximately the same for both the normal (useful) life distribution and the wear-out distribution.
Answer:
Step-by-step explanation:
From the missing information;
Lets assume that;
[tex]\text{the exponential distribution mean = 500 thousand naira}[/tex]
[tex]\text{Range 100 thousand}[/tex] → [tex]\text{1 million naira}[/tex]
∴
a)
[tex]X \sim exp (\dfrac{1}{500}) \\ \\ P( X \le x) = 1 - e^{\dfrac{-x}{500}} \\ \\ P(X < 700) = 1 - e^{\frac{-7}{5}} \\ \\ \mathbf{P(X< 700) = 0.75340}[/tex]
b)
[tex]Y \sim \cup (100,1000) \implies P(Y \le y ) = \dfrac{y - 100}{1000-100} \\ \\ P(Y < 700) = \dfrac{600}{900} = 0.67[/tex]
c)
[tex]P(X < 830)= 1 - e^{\frac{-830}{500}} \\ \\ P(X < 830)= 1 - 0.1901 \\ \\ P(X < 830)=0.8099 \\ \\ P(Y < 830) = \dfrac{730}{900} = 0.8111 \\ \\ Thus;\mathbf{ P(X < 0.8099) = P(Y< 0.8111)}[/tex]

What is the median of 6,14,2,7,12,3
Answer:
6.5
Step-by-step explanation:
First you make the list in ascending order.
2, 3, 6, 7, 12, 14
There are six numbers, therefore two numbers could qualify for the "middle number". So, 6 and 7 can qualify, therefore the average of those numbers would be the median. 6+7 = 13 and 13/2 is 6.5

|x+3|, if x>5
I really need help were supposed to be using the absolute value!! If you can add an explanation that would be great!!
Answer:
Step-by-step explanation:
Suppose x+3 < 0. Subtract 3 from both sides of the inequality.
x < -3
So, x+3 is negative when x < -3. When x>5,
x+3 > 8, which is positive, so the absolute value function has no effect.
|x+3| > 8

How do you convert a fraction or decimal to a percent?
Answer:
a
Step-by-step explanation:
Answer:
To convert a decimal to a percent, multiply it by 100 (move the decimal place two digits to the right) and add the "%" sign.
A fraction must be converted into a decimal first by dividing the denominator into the numerator, then converting that answer to a percent like above.

Answer:
9. B. 32 millimeters
10. C. 7 inches
11. C. 56.24 millimeters
13. B. 14.13 square feet
Step-by-step explanation:
9. Radius of a circle or any circular shape = ½ of its diameter
Diameter of the disk = 64 millimeters
Radius of the disk = ½(64) = 32 millimeters
10. Width of the cooler = 6 in.
Length = 8 in.
Volume = 336 in.³
Height = ?
Formula for volume of a rectangular prism = L*W*H
Plug in the values
336 = 8*6*H
336 = 48*H
Divide both sides by 48
336/48 = H
H = 7 inches

c reflexive property
if you look at it it's reflecting
=============================================================
Explanation:
For statement 1, we'll have angle O congruent to angle M. This is visually given by the angle arcs that are the same.
For statement 2, we'll have segment OL congruent to segment LM. This is also given because of the tickmarks on the segments to show they are the same length.
In statement 3, angle KLO is congruent to angle MLN. The reason for this is they are vertical angles. So if your teacher was asking about what goes for reason 3, then you would be correct in selecting choice A.
The actual answer is choice B) ASA because we have two pairs of congruent angles (refer to statements 1 and 3 mentioned earlier); between those angles for each triangle we have a pair of congruent segments (refer to statement 2). So that's why we go for ASA. As you can probably guess, "A" stands for "angle" and "S" stands for "side". The order matters. The side must be between the angles in question. This means AAS is slightly different than ASA.
Side note: The reflexive property is the idea that any segment or angle is congruent to itself. It's not used at all here, but it's useful in other situations.
Another side note: CPCTC stands for "corresponding parts of congruent triangles are congruent". It basically means that if two triangles are congruent, then the pieces that match up together are congruent as well.
Suppose that a cylinder has a radius of r units, and that the height of the cylinder is also r units. The lateral area of the cylinder is 338 square units. Find the value of r.
Answer:
r = 7.33 units
Step-by-step explanation:
Given that,
A cylinder has a radius of r units, and that the height of the cylinder is also r units.
The lateral area of the cylinder is 338 square units.
We need to find the value of r.
The formula for the lateral area of the cylinder is given by :
[tex]A=2\pi rh[/tex]
Put all the values,
[tex]2\pi r^2=338\\\\r=\sqrt{\dfrac{338}{2\pi}} \\\\r=7.33\ unit[/tex]
So, the value of r is equal to 7.33 units.

a bag contains 1 red beads,2 yellow beads,2 green beads and 1 blue beads
a bead is chosen at random
a)what is probability that it is green ?
b)what probability that it is green or yellow
Answer:
a) 2/6 b) 4/6
Step-by-step explanation:
You add the amount of beads: 1+2+2+1= 6
And take the amount of green beads and put it over the total amount so 2/6
For b you do the same but add the green and yellow beads and put that over the total amount 4/6
Answer:
Step-by-step explanation:
a) 2/6 = 1/3
b) green or yellow = (2/6 x 1/5) + (2/6 x 1/5) = 1/15 x 1/15 = 1/225

Step 1: Simplify both sides of the equation.
y+4=10.7
Step 2: Subtract 4 from both sides.
y+4−4=10.7−4
y=6.7
Answer: The subtraction property of equality or move the 4 to the other side using subtraction.
Step-by-step explanation:
4+y = 10.7

You can change mixed numbers by changing it into an improper fraction.
Step-by-step explanation:
g A mid-sized tech company believes that 60% of its employees get no regular exercise, 25% exercise sporadically, while 15% engage in regular exercise. You suspect that this numbers may have changed due to a recent exercise campaign targeting the company employees. From a random sample of 470 employees, you find that 255 do not engage in regular exercise, 125 exercise sporadically, and 90 engage in regular exercise. Based on this data, is there enough evidence to suggest that the numbers have changed
Answer:
Based on this sample data, there is enough evidence to suggest that the numbers have changed.
The number of those who do not do regular exercise has reduced from 60% to 54%. The number of those who do sporadic exercise has increased from 25% to 27%. The number of those who engage in regular exercise has increased from 15% to 19%.
So the numbers have changed much.
Step-by-step explanation:
No Regular Sporadic Regular
Exercise Exercise Exercise Total
Estimated proportion 60% 25% 15% 100%
Random sample 255 125 90 470
Random proportion 54% (255/470) 27% (125/470) 19% (90/470) 100%
