The lifetime of meson according to laboratory clocks would be 14 μs.
In this question,
Meson decay, Δt = 2μs
Velocity, y = 0.99C, where C is the speed of the light
Time measurement depends on the reference frame of clock.
Time dilation, Δt' = y Δt
⇒ [tex]\frac{\Delta t }{\sqrt{1-\frac{v^{2} }{c^{2} } } }[/tex]
⇒ [tex]\frac{2(10^{-6} ) }{\sqrt{1-\frac{(0.99c)^{2} }{c^{2} } } }[/tex]
⇒ [tex]\frac{2(10^{-6} ) }{\sqrt{1-0.99^{2} } } }[/tex]
⇒ [tex]\frac{2(10^{-6} ) }{\sqrt{1-0.9801 } } }[/tex]
⇒ [tex]\frac{2(10^{-6} ) }{\sqrt{0.0199} } }[/tex]
⇒ [tex]\frac{2(10^{-6} ) }{0.1410} } }[/tex]
⇒ 14.18 × 10⁻⁶ ≈ 14 μs
Hence we can conclude that the lifetime of meson according to laboratory clocks would be 14 μs.

If amy cuddy and her research team originally established a sample size of n=200 (100 in each group) and then discovered that 86% of the high-power group (86 of 100) took a gambling risk while 60% of the low-power group (60 of 100) took the risk, then the p-value would have been much lower than that originally found in question 1. this p-value would have been less sensitive and would have provided stronger evidence for the researcher's hypothesis. state the p-value, rounding to 5 decimal places.
The p-value that would be given as the evidence would be given as p-value = 0.00002 and also P value = 0.00003
How to solve for the p valueThe sample size of the first sample = 100
x1 = success 0f 86%
We have to find the proportion of this = 0.86
The sample size of the second sample n2 = 100
x12 = success 0f 60%
We have to find the proportion of this = 60/100
= 0.6
The difference = 0.86-0.6= 0.26
Next we have to find the pooled proportion. This is taken given as p = (x1+x2)/(n1+n2) this gives us 0.73
Next we have to find the standard error
= √(p*(1-p)*(1/n1+ 1/n2)= 0.06279
Z stat = (0.26-0)/0.0628= 4.1411

Amanda would use 3 planks of lengths 3 feet, 5 feet, and 6 feet.
What is a triangle?A triangle is a three-edged polygon with three vertices. It is a fundamental shape in geometry. Triangle ABC denotes a triangle with vertices A, B, and C. In Euclidean geometry, any three non-collinear points define a unique triangle and, by extension, a unique plane.To determine which planks Amanda should use to build the triangular-shaped kennel:
To build a kennel for dog, we would try to make it the largest possible with what we have.So, we would go with the 3 longest planks: 3ft, 5ft, and 6ft.By looking at the length, we see that we could make something very close to a right triangle since we could use the 6ft as a hypotenuse, and have the two other sides as 3ft and 5 ft (6² is almost 3²+5², which equals 34).That means our corner angle would be slightly over 90 degrees.Therefore, Amanda would use 3 planks of lengths 3 feet, 5 feet, and 6 feet.

An architectural drawing lists the scale as 1/4" = 1'. If a bedroom measures 634" by 412" on the drawing, how large is the bedroom?
For a bedroom measuring 6 3/4" by 4 1/2" on the drawing, the dimensions of the bedroom are 18 ft. by 27 ft.
Option (C) is correct.
In mathematics, a dimension is the length or width of an area, region, or space in one direction. It is just the measurement of an object's length, width, and height.
According to the question,
The scale of an architectural sketch is 1/4" = 1'. If, according to the drawing, a bedroom has the dimensions 6 3/4 by 4 1/2 inches.
Then, the dimensions of the bedroom in feets are calculated as follows:
As 1/4" = 1'
6 3/4" = 27'= 27 ft.
Similarly,
4 1/2" = 18' =18 ft.

Answer:
○ [tex]3x + 4y = 7[/tex]
Step-by-step explanation:
The general form of the equation of a straight line is as follows:
[tex]\boxed{y = mx + c}[/tex],
where:
m = slope
c = y-intercept.
This means that m, which is the coefficient of [tex]x[/tex], needs to be [tex]-\frac{3}{4}[/tex].
Therefore we have to rearrange each equation given to make y the subject, and then check if the coefficient of [tex]x[/tex] becomes [tex]-\frac{3}{4}[/tex].
• First option:
[tex]4x - 3y = 7[/tex]
⇒ [tex]-3y = -4x + 7[/tex]
⇒ [tex]y = \frac{4}{3}x -{ \frac{7}{3}[/tex]
∴ 'm' is [tex]\bf \frac{4}{3}[/tex], not [tex]-\frac{3}{4}[/tex], therefore this option is incorrect.
• Second option:
[tex]4x + 3y = 7[/tex]
⇒ [tex]3y = -4x + 7[/tex]
⇒ [tex]y = -\frac{4}{3}x + \frac{7}{3}[/tex]
∴ 'm' is [tex]\bf -\frac{4}{3}[/tex], not [tex]-\frac{3}{4}[/tex], therefore this option is incorrect.
• Third option:
[tex]3x + 4y = 7[/tex]
⇒ [tex]4y = -3x + 7[/tex]
⇒ [tex]y = -\frac{3}{4}x + \frac{7}{3}[/tex]
'm' is [tex]\bf -\frac{3}{4}[/tex], therefore this option is correct.
Note:
You can rearrange the equation given in the last option, and see that 'm' comes out to be [tex]\frac{3}{4}[/tex], thereby making it incorrect.

What is the maximum value of the transformed function, y = -3cos (2x - 8) + 5
A. 3 units
B. 5 units
C. 8 units
D. 11 units
Answer:
C. 8 units.
Step-by-step explanation:
The maximum value of the cosine ( cos) function is 1
So, for y = 3cos(2x - 8) + 5
Maximum value is 3 *1 + 5 = 8.
y = -3cos(2x - 8) + 5 is the above graph reflected in the y axis so the maximum value is also 8.

Statistics refers to the method of collecting data for the purpose of analysis, making of inferences and drawing of conclusions about the data collected.
Statistics usually involve numerical data in large quantities.
Statistical data can be used to make predictions about future events. They are also used to make decisions. For example, the statistical data of soccer players such as games/goal ratio, number of complete dribbles per match, number of successful take-ons, number of tackle or interceptions per game can be used in deciding which soccer player a football team should buy.
In the given scenario, Coach Salinas wants to compare the kicking statistics for kickers on their team in order to find the kicker with the greatest goal success rate.

The double number lines show the ratio of yards to miles.How many yards are in 4 miles?
Using proportions, considering the ratio given in the double number line, it is found that there are 7.04 yards in 4 miles.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.
Researching the problem on the internet, it is found that there are 3.52 yards in 2 miles. Hence the following rule of three is used to find the number of yards in 4 miles.
2 miles - 3.52 yards
4 miles - n yards
Applying cross multiplication:
2n = 4 x 3.52
Simplifying by 2:
n = 2 x 3.52
n = 7.04 yards.
