The value of the unknown variable is 12.6.

A triangle is a two - dimensional figure with three sides and three angles.

The sum of the angles of the triangle is equal to 180 degrees.

∠A + ∠B + ∠C = 180°

Given is a right angled triangle as shown in the image.

There are six major trigonometric functions as -

We can write the relation between them as -

We can write the value of the unknown variable {x} as -

sin(57°) = x/15

sin(57°) = x/15

x = 15 sin(57°)

x = 15 x 0.838

x = 12.6

So, we can conclude that the value of the unknown variable is 12.6.

Therefore, the value of the unknown variable is 12.6.

Answer:

Just a rough try of the STRUCTURE, not the actual. Use a protractor.

Answer:

The radius (r) of a soccer ball with a volume of 288 cm3 is 6 cm.

Step-by-step explanation:

the total angles in the triangle are 180°

so,

63° + 57° + ∠2 = 180°

120° + ∠2 = 180°

∠2 = 180° - 120°

∠2 = 60°

Answer:

C. No, the Normal/large sample condition is not met.

Step-by-step explanation:

There is only 20 cup and for a sample to meet the Normal/large sample condition it must be greater than 30 samples or have a normal distribution or have no skewness or outliers  

No, the Normal/large sample condition is not met.

Option C is the correct answer.

A t-test is a statistical test used to determine whether there is a significant difference between the means of two groups or samples.

It is used when the sample size is small or the population standard deviation is unknown.

We have,

The conditions for inference in a t-test are:

Random condition:

The sample should be selected randomly from the population to ensure that the sample is representative of the population.

Normal/large sample condition:

The population should be normally distributed, or the sample size should be large enough to assume normality. A commonly used rule of thumb is that the sample size should be at least 30.

Independence condition:

The observations in the sample should be independent of each other.

In this case,

The random condition is met as the sample was selected randomly. However, the normal/large sample condition is not met since the sample size is only 20, and it's not clear if the population of coffee temperatures is normally distributed.

Therefore, the conditions for inference are not met, and a t-test for the population mean temperature of all cups of coffee served at this restaurant cannot be conducted.

Thus,

No, the Normal/large sample condition is not met.

The image of the hexagon is missing, so i have attached it.

Answer:

∠1 = 36°

Step-by-step explanation:

From the image attached, we can see that the polygon is regular and has 10 sides.

Formula for an interior angle of a regular polygon is;

θ = 180(n - 2)/n

Where n is the number of sides of the polygon.

Thus;

θ = 180(10 - 2)/10

θ = 144°

Now, ∠1 forms a straight line with one of the interior angles of the polygon.

Thus, θ + ∠1 will be equal to 180° because sum of angle on a straight line is 180°

Thus;

144° + ∠1 = 180°

∠1 = 180° - 144°

∠1 = 36°

Answer:

[tex]6.3m/s[/tex]

Step-by-step explanation:

Note: We will take g as 9.8 in this question.

The two equations we will use for this questions are:

[tex]G.P.E = mgh[/tex], m = mass, g = acceleration due to gravity

and the SUVAT equation: [tex]v^2=u^2+2as[/tex]

First, let's start out by finding the height from which the object is being dropped. We can do this by using the gravitational potential energy formula.

Subbing the values we have:

[tex]50 = 2.5*9.8*h[/tex]

[tex]h = 2.04[/tex] - re-arranging for the height we get a height of 2.04.

Now we will use the SUVAT equation. Let's set out the variables we have:

[tex]S=2.04\\U=0\\V=?\\A=9.8\\T=N/A[/tex]

U (initial speed) is equal to 0 because we are dropping the object from rest. Acceleration is equal to 9.8 as that is the acceleration due to gravity. The displacement (S) is the height we just worked out.

Now let's put them into one of the SUVAT equations:

[tex]v^2=u^2+2as[/tex]

[tex]v^2=(0)^2+2(9.8)(2.04)[/tex]

[tex]v^2=39.984[/tex]

[tex]v=6.3 m/s[/tex]

Answer:

6^6 = 36 (squared my radius in order to find the area of one circle)

36 x 3.14(multiplied my radius by pi to find the area) = 113.04

Now we multiply the area of one circle with the height since it is a prism throughout the whole shape.

113.04 x 9 = 1,017.36 in^3 is your answer.

Step-by-step explanation:

Formula of area of a circle:

pi(3.14 or 22/7 depending on what they tell you to use for pi) x radius squared(your radius is half of your diameter or given radius, your radius should be squared in order to find the area).

Answer: $826.8

Step-by-step explanation:

First, we add the amount of money that the machines sold for:

$420 + $360 = $780

Next, we multiply it by the sales tax, 6%,

$780 x 6%(0.06) = $46.80

Finally, we add this to the total:

$780 + $46.80 = $826.80

Alternatively, you can add the total sales and multiply by 106% using the 2-step method.
