20. GEOMETRY The measures of two sides of a triangle are given. If p isthe perimeter, and p=10x+5y, find the measure of the thir

algol [13]

The perimeter of any shape is a measure of the length of the peripheral of that shape.

For a triangle, it is an addition of the length of the 3 sides.

P = a + b + c where a, b, c are the lengths of the individual sides.

p = 10x + 5y = (3x + 4y) + (5x - y) + c

Collecting like terms on the RHS, we have

p = 10x + 5y = 8x + 3y + c

Subtracting 8x + 3y from both sides to give c leaves us with

10x + 5y - (8x + 3y) = c

c = 10x - 8x + 5y - 3y

c = 2x + 2y

The price-to-earning ratio for firms in a given industry is distributed according to normal distribution. In this industry, a fi

dmitriy555 [2]

Answer:

Option a) Has an above average price-to-earning ratio

Step-by-step explanation:

We are given the following in the question:

The price-to-earning ratio for firms in a given industry is distributed according to normal distribution.

For a particular firm the ratio x has a standard normal variable has a value,

z = 1

Formula:

$z_{score} = \displaystyle\frac{x-\mu}{\sigma}$

$1 = \dfrac{x - \mu}{\sigma}\\\\\sigma = x - \mu\\x = \mu + \sigma$

Thus, the firm has an above average price-to-earning ratio as the ratio is one standard deviation above the mean.

Option a) Has an above average price-to-earning ratio

For a trapezoid, the following formula relates the area a, the two bases a and b, and the height h. a= g (a

Dovator [93]

A - area of a trapezoid;
a, b - two bases.
A = h * ( a + b ) / 2 / * 2 ( we have to multiply both sides by 2 )
2 A = h *( a + b )
2 A = h a + h b
h b = 2 A - h a
b = ( 2 A - h a ) / h
b = 2 A/h - a
Answer: D )

The manager of a factory wants to compare the mean number of units assembled per employee in a week for two new assembly techniq

antoniya [11.8K]

Answer:

The most appropriate inferential statistic test in the present situation is the;

b. Two-sample t-test

Step-by-step explanation:

From the question, we have;

The number of subjects in each sample, n₁ = 100

The number of samples = 2

The nature of the test = To compare the two means

The value of the population standard deviation, σ = Unknown

From the given parameters, we have;

The t-test is a method of inferential statistics for determining whether the difference between the mean of two groups is significant, that is if the observed difference are due to chance, where the groups are likely to have some characteristics that are related

The t-test is utilized when testing an hypothesis, and it is used for small samples, where the population standard deviation is unknown

The types of t-test used are;

a) One-sample t-test

b) Two-sample t-test

c) Paired Sample t-test

Therefore, a two-sample t-test is most appropriate.
