Answer:

80°

Step-by-step explanation:

let make suppose angle x°

x°+45°+55°= 180 { the sum of angle of triangle is 180°}

or, x° + 100° = 180°

or, x° = 180° - 100°

or, x° = 80°

x°= 80°

Answer:

1.25x

Step-by-step explanation:

Given that :

25% Increase in number of blog views can be expressed as (x + 0.25x)

Another way to make this representation is :

Total number of blog views + 25% of total

Total should add up to 100%

Let number of views = x

Hence,

(100% + 25%) of x

125% of x

125%x

= 1.25x

Answer:

A. The value of the parameter is 0.1002 km⁻¹

B. The probability that the extent of daily sea-ice change is within 1 standard deviation of the mean value is 0.651.

a. We are given that the density function of the double exponential distribution is:

f(x) = λ/2 * exp(-λ|x|)

where λ is the parameter to be determined.

We know that the standard deviation of this distribution is 40.9 km. The standard deviation of a double exponential distribution is given by:

σ =√(2)/λ

Substituting σ = 40.9 km, we get:

40.9 = √(2)/λ

λ = √2)/40.9

λ ≈ 0.1002 km⁻¹

b. To find the probability that the extent of daily sea-ice change is within 1 standard deviation of the mean value, we need to find the probability that the random variable X lies between µ - σ and µ + σ, where µ is the mean value of the distribution.

The mean value of a double exponential distribution is given by:

µ = 0

So, we need to find the probability that |X| < σ, which can be written as:

P(-σ < X < σ) = P(X < σ) - P(X < -σ)

Using the cumulative distribution function (CDF) of the double exponential distribution, we get:

P(X < σ) = (1/2) * [1 - exp(-λσ)]

P(X < -σ) = (1/2) * [1 - exp(λσ)]

Substituting λ ≈ 0.1002 km^-1 and σ = 40.9 km, we get:

P(-σ < X < σ) = P(X < σ) - P(X < -σ) ≈ 0.651

Therefore, the probability that the extent of daily sea-ice change is within 1 standard deviation of the mean value is approximately 0.651.

Yes, the data indicate that the machinery should be repaired and the hypotheses are stated.

In this scenario, the null hypothesis is that the machinery is not producing more than 10% defective items, while the alternative hypothesis is that it is producing more than 10% defectives. We can represent these hypotheses as follows:

H0: The machinery is not producing more than 10% defectives.

Ha: The machinery is producing more than 10% defectives.

To test the hypothesis, we will use a statistical test called the one-sample proportion test. This test compares the sample proportion to a hypothesized population proportion. In this case, the hypothesized proportion is 0.10 (10% defectives).

Using the one-sample proportion test, we can calculate a p-value, which is the probability of obtaining a sample proportion as extreme as the one observed or more extreme, assuming the null hypothesis is true. If the p-value is less than the significance level, we reject the null hypothesis in favor of the alternative hypothesis.

In this scenario, the sample proportion is 0.15 (15 defectives out of 100 items), and the hypothesized population proportion is 0.10 (10% defectives). Using a one-tailed test with a significance level of 0.05, we can calculate the p-value as 0.0347.

Since the p-value is less than the significance level, we reject the null hypothesis and conclude that the machinery is producing more than 10% defectives. Therefore, the machinery should be repaired to reduce the defect rate.

Explanation:

You could use any two points you want. For me, the easiest is when x = 0. Plug this into the equation to get

y = 2x-7

y = 2(0)-7

y = -7

So we have x = 0 and y = -7 pair up to get (0,-7) as our first point. This is the y intercept.

Repeat for x = 1

y = 2x-7

y = 2(1)-7

y = -5

So (1,-5) is another point on this line. You only need two points at minimum to graph a straight line.

Answer:

y = - \(\frac{1}{3}\) x + 5

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

calculate m using the slope formula

m = \(\frac{y_{2-y_{1} } }{x_{2-x_{1} } }\)

with (x₁, y₁ ) = (0, 5) and (x₂, y₂ ) = (3, 4) ← 2 points on the line

m = \(\frac{4-5}{3-0}\) = \(\frac{-1}{3}\) = - \(\frac{1}{3}\)

the line crosses the y- axis at (0, 5 ) ⇒ c = 5

y = - \(\frac{1}{3}\) x + 5 ← equation of line

5. The total displacement is 0

Step-by-step explanation:

There are 5 full square and 6 triangles that are half squares.

      5 + (6)(1/2) = 5 + 3 = 8

You could also break this into smaller shapes (like a big triangle on the top and a smaller triangle and rectangle on the bottom and use area formulas to calculate the area.  But counting works well in this example.

Answer: 8

Step-by-step explanation:

First you split up this shape into two different shapes, a triangle and trapezoid

Put a line through the coordinates (-2,2) to  (-1,2); the top is a triangle and the other is a trapezoid

Area of the trapezoid is A = .5x (base1 + base2) x height

base1 of the trapezoid goes from -4 to -1 which is 3

base2 goes from -2 to -1 which is 1

height is 0 to 2 whcich is 2

A = .5 x (3+1) x 2 = 4

Now area of a triangle is A = .5 x base x height

the base goes from -2 to 2 which is 4

the height goes from 2 to 4 which is 2

A = .5 x (4) x (2) = 4

Area of the Trapezoid + Area of the Triangle = Total Area

4 + 4 = 8

There will always be at least two blue balls that are adjacent to each other.

To show that no matter how the balls are arranged, after they are painted, there will always be at least two blue balls that are adjacent to each other, we can use the Pigeonhole Principle.

First, let's consider the worst-case scenario, which is when the blue balls are arranged such that they are as spread out as possible. In this case, we can imagine that the 15 white balls are arranged in a straight line, with 7 blue balls and 8 green balls interspersed in such a way that there are no two blue balls that are adjacent to each other.

Now, let's place each of the 7 blue balls in a pigeonhole that corresponds to their position in the line. Specifically, the first blue ball goes in the first pigeonhole, the second blue ball goes in the second pigeonhole, and so on, until the seventh blue ball goes in the seventh pigeonhole.

Since there are only 7 pigeonholes and 7 blue balls, at least one pigeonhole must contain two blue balls. And since the only way for two blue balls to be in the same pigeonhole is for them to be adjacent to each other in the line, we have shown that no matter how the balls are arranged, after they are painted, there will always be at least two blue balls that are adjacent to each other.

Answer:

A

Step-by-step explanation:

The only equation that follows what it says.

Answer:

no

Step-by-step explanation:

If the relationship is not one-to-one, it can still be regarded as a function if it is a many-one relationship, which means that the function has the same y value for a variety of x values.

This cannot be a function if we flip it around and make it a one-to-many relationship since the same input cannot produce various results.

A function can be defined as the outputs for a given set of inputs.

The inputs of a function are known as the independent variable and the outputs of a function are known as the dependent variable.

If the relation is not one-to-one it can still be considered as a function if it is a many-one function meaning for some different values of x the function has the same y value.

If we reverse this and make it a one to many it will not function as

same input can not lead to different outputs.

#SPJ5

Answer:

x = 2.52

Step-by-step explanation:

30.16 = 17.56 + 5x

30.16 - 17.56 = 5x

12.6 = 5x

12.6/5 = 5x/5

2.52 = x

The answer you are looking for is x=-2.

Solution/Explanation:

Writing out the equation

3[-x+(2x+1)]=x-1

Simplifying inside of the brackets first

Combining like terms, since -x+2x=x

3(x+1)=x-1

*You can remove the parenthesis, if preferred.

Using the Distributive Property on the left side of the equation

3x+3=x-1

Now, subtracting the "x" variable from both sides

3x+3-x=x-x-1

"x-x" cancels out to 0.

3x+3-x=-1

Combining like terms and simplifying

3x-x+3=-1

2x+3=-1

Subtracting 3 from both sides of the equation

2x+3-3=-1-3

"3-3" cancels out to zero.

2x+0=-1-3

2x=-1-3

Simplifying the right side of the equation

2x=-4

Finally, dividing both sides by 2

2x/2=-4/2

Simplifying the final part of the problem

Since 2x/2=x and -4/2=-2

x=-2

So, therefore, the final answer is x=-2.
