[tex]\qquad\displaystyle \tt \dashrightarrow \: x = 20[/tex]

Value of x = 20°

Hey! there . Thanks for your question :)

Answer:

Step-by-step explanation:

In this question we are given with two interior angles of the triangle that are 40° and 70° , also we are given an exterior angle that is (5x + 10)°. And we are asked to find the value of angle x.

Solution :-

For finding the value of angle x , we have to use exterior angle property of triangle which states that sum of opposite interior angles of triangle is equal to the given exterior angle. So :

Step 1: Making equation :

[tex] \longmapsto \: \sf{40 {}^{°} + 70 {}^{°} = (5x + 10) {}^{°} }[/tex]

Solving :

[tex] \longmapsto \: \sf{110 {}{°} = (5x) {}^{°} +10 {}^{°} }[/tex]

Step 2: Subtracting 10 on both sides :

[tex] \longmapsto \sf{ 110 {}^{°} - 10 {}^{°} = 5x + \cancel{10 {}^{°}} - \cancel{10 {}^{°} } }[/tex]

We get ,

[tex] \longmapsto \sf{(5x ){}^{°} = 100 {}^{°} }[/tex]

Step 3: Dividing both sides by 5 :

[tex] \longmapsto \dfrac{ \cancel{5}x {}^{°} }{ \cancel{5}} = \dfrac{ \: \: \: \: \cancel{ 100} {°}^{} }{ \cancel{5} }[/tex]

On cancelling , we get :

[tex] \longmapsto \underline{\boxed{\red{\sf{ \bold{ x = 20 {}^{°} }}}}} \: \: \bigstar[/tex]

Verification :-

For verifying sum of both the interior angles is equal to given exterior angles. As we get the value of x as 20 we need to substitute it's value in place x and then L.H.S must be equal to R.H.S :

Therefore , our answer is correct .

Teresa's result of 95 heads is slightly higher than what she would have expected, it is still reasonably close to the expected value based on the theoretical probability of getting a head when flipping a fair coin.

Teresa's result of 95 heads in 150 coin flips is slightly higher than what she would have expected if the theoretical possibility of getting a head when flipping a coin was exactly 1/2.

When flipping a fair coin, the probability of getting a head is indeed 1/2, and the probability of getting a tail is also 1/2. Therefore, if we assume that the coin is fair and unbiased, we can use the concept of expected value to determine what Teresa would have expected.

The expected value of a single coin flip can be calculated as follows:

Expected value = (Probability of an outcome) * (Value of the outcome)

In this case, the probability of getting a head is 1/2, and the value of getting a head is 1 (since we are interested in the number of heads). Therefore, the expected value of a single coin flip is:

Expected value = (1/2) * 1 = 1/2

To determine what Teresa would have expected in 150 coin flips, we can multiply the expected value of a single coin flip by the number of flips:

Expected number of heads = (Expected value) * (Number of coin flips)

Expected number of heads = (1/2) * 150 = 75

So, if Teresa had flipped the coin 150 times and the coin was fair, she would have expected to get approximately 75 heads.

However, Teresa obtained 95 heads in her actual experiment. This result is slightly higher than the expected value of 75 heads. It's important to note that, due to the inherent randomness of coin flips, there will always be some variation between the expected and actual results. Flipping a coin 150 times is a relatively small sample size, and it is within the realm of possibility to deviate from the expected outcome.

Therefore, while Teresa's result of 95 heads is slightly higher than what she would have expected, it is still reasonably close to the expected value based on the theoretical probability of getting a head when flipping a fair coin.

The area under the curve y = x² + 5x + 4 and the x-axis is [tex]1\frac{2}{3}[/tex] square units.

To find the area under the curve y = x² + 5x + 4 and the x-axis, we need to integrate the given function over a specific interval.

We need to find the definite integral of the function over a suitable interval.

Let's find the definite integral of the function from its roots (where the curve intersects the x-axis).

First, let's find the roots of the function by setting y = 0:

x² + 5x + 4 = 0

Factoring the quadratic equation:

(x + 1)(x + 4) = 0

Setting each factor equal to zero:

x + 1 = 0 => x = -1

x + 4 = 0 => x = -4

The roots of the function are x = -1 and x = -4.

To find the area under the curve, we integrate the function from x = -4 to x = -1:

∫[x=-4 to -1] (x² + 5x + 4) dx

Integrating the function:

∫[x=-4 to -1] (x² + 5x + 4) dx = [1/3x³ + (5/2)x² + 4x] from -4 to -1

Substituting the limits:

[1/3(-1)³ + (5/2)(-1)² + 4(-1)] - [1/3(-4)³ + (5/2)(-4)² + 4(-4)]

Answer:

0.15 flowers/ ft²

Step-by-step explanation:

area = 12 X 18 = 216.

population density = population/area

= 32/216

= 0.148

= 0.15 flowers/ ft²

Answer:

A. 0.15 flowers/ft²

Step-by-step explanation:

The population density of flowers is the number of flowers per square foot.

To find the population density, we need to know the area of the garden and the number of flowers.

The area of the garden is 12 feet*18 feet =216 square feet.

The number of flowers is 32.

The population density is 32flowers/216square feet = 0.15 flowers/ft².

Therefore, the answer is (A).

The length of PQ in circle R is given as follows:

C) 3.14 m.

The circumference of a circle of radius r is given by the equation presented as follows:

C = 2πr.

The radius for the circle in this problem is given as follows:

r = 3 m.

Hence the circumference for the entire circle is given as follows:

C = 2 x 3.14 x 3

C = 18.84 m.

The sector has an angle measure of 60º, while the entire circumference is of 360º. hence the measure of arc PQ is given as follows:

PQ = 60/360 x 18.84

PQ = 3.14 m.

The phrase "it will be tacitly understood that each such formula can be written in a form that only involves ∈ and = as nonlogical symbols" implies that although we may use certain symbols such as defined predicates, operations, and constants in our formulas, the underlying assumption is that these symbols can ultimately be expressed or defined using the fundamental symbols of set membership (∈) and equality (=).

Symbols can always be represented using set membership and equality symbols. We simplify formulas by eliminating unnecessary symbols through this convention.

If we define predicate "P," any formula with "P" can be expressed using set membership and equality. We can translate any formula with "P" into one using only ∈ and =. By adopting this convention, we ensure clear and precise communication, with a well-defined language and logical structure for formulas.

Answer: B

Step-by-step explanation:

The coefficients 9 & 6, divided by 3, equal 3 & 2.

For the exponents, if you divide the entire equation by xy, you need to subtract the corresponding exponents of x and y. Subtract the denominator's exponent from the numerator's exponent.

So, for the first part x^8/x^1=x^7

y^2/y^1=y

For the second part: x^3/x=x^2

y^4/y=y^3

So, if you put the coefficients and both parts of the equation together, you get 3x^7y - 2x^2y^3 (answer letter B).

The product of the fractions is 1/[(x - 5)(x + 7)]

From the question, we have the following parameters that can be used in our computation:

Fraction 1 = (x + 1)/(x² - 25)

Also, we have

Fraction 2 = (x + 5)/(x² + 8x + 7)

So, we have

Product = (x + 1)/(x² - 25) * (x + 5)/(x² + 8x + 7)

When factored, we have

Product = (x + 1)/(x - 5)(x + 5) * (x + 5)/(x + 1)(x + 7)

Evaluate the products

Product = 1/(x - 5) * 1/(x + 7)

This gives

Product = 1/[(x - 5)(x + 7)]

Hence, the product of the fractions is 1/[(x - 5)(x + 7)]

|−25| = 25

|−1.23| = 1.23

|0.45| = 0.45

Now, let's identify whether the following numbers are rational or irrational:

234: This is a rational number because it can be expressed as a fraction (e.g., 234/1).

5–√: This is an irrational number because it cannot be expressed as a fraction or a ratio of integers. The square root of 5 is not a perfect square, so it is irrational.

To convert the decimal 0.44444... to a fraction, we can set it as the variable x and solve the equation:

x = 0.44444...

Multiply both sides by 10 to move the decimal point:

10x = 4.44444...

10x - x = 4.44444... - 0.44444...

9x = 4

The meaning of "The field of a relation R" is a constraint on the values that can be stored in that attribute.

We are given that;

The statement The field of a relation R

Now,

According to the web results, the field of a relation R is the set of all values that appear in the relation R. In other words, it is the union of all the attributes (columns) of R. For example, if R is a relation with attributes A, B, and C, then the field of R is the set of all values that appear in A, B, or C. The field of R can also be denoted by F.

The field of a relation is different from the domain of an attribute, which is the set of all possible values that an attribute can take. For example, if A is an attribute that can only take integer values, then the domain of A is the set of all integers. The domain of A may be larger than the field of A, which is the set of all values that actually appear in A. The domain of an attribute defines a constraint on the values that can be stored in that attribute.

Therefore, by the domain the answer will be a constraint on the values that can be stored in that attribute.
