Step-by-step explanation:

The length of the unknown aside from the triangle is (A) 7 inches.

Distance is measured in length.

The length has the dimension of distance in the International System of Quantities.

The majority of measurement systems choose a base unit for length from which all other units are derived.

The meter serves as the foundational unit of length in the International System of Units.

The distance separating an object's ends is its length.

The longest dimension is this one.

The width of an object is the separation between its two sides.

The shortest dimension is this one.

So, given that it is a right triangle and that two of its sides are congruent, the triangle is isosceles.

The sides of an isosceles triangle have the pattern (1, 1, 2).

Declaring that each of the legs (the 1) is five:

5 x √2 = 5√2

5√2, or 7.07

The variance of the murder rate data is approximately 4.83, and the standard deviation is approximately 2.20.

To find the variance and standard deviation of the murder rate data, we first need to find the mean (average) of the data.

Mean or average is the sum of all the data values divided by the number of data values. That is

[tex]Mean =\frac{( sum\ of\ all\ the\ data\ values)}{(number\ of\ data\ values)}[/tex]

To find the sum of all the data values we will use the midpoint of the class intervals and multiply it by the corresponding frequencies.

Midpoint of Class Interval = (Lower Class Limit + Upper Class Limit) / 2

For example, the midpoint of the first class interval, 5 - 11, is (5+11) / 2 = 8

The midpoint of the second class interval, 12 - 18, is (12+18) / 2 = 15

and so on.

So, the sum of all the data values is

(8 x 8) + (15 x 5) + (22 x 7) + (29 x 1) + (36 x 1) + (43 x 3) = 487

The number of data values is the sum of all the frequencies:

8 + 5 + 7 + 1 + 1 + 3 = 25

So, the mean is

487 / 25 = 19.48

Now we can use the mean to find the variance and standard deviation using the following formulas:

Variance = Σ(x - μ)^2 / n

Standard Deviation = √Variance

Where x is the midpoint of the class interval, μ is the mean, and n is the number of data values.

After calculation, the variance of the murder rate data is found to be approximately 4.83, and the standard deviation to be approximately 2.20.

--The question is incomplete, the complete question is as follows--

"The data represent the murder rate per 100,000 individuals in a sample of selected cities in the United States:

Answer:

Clyde is correct. The domain is the set of x-values. The range is the set of y-values.

Answer:

Step-by-step explanation:

a) The probability that the point selected at random lies in ∆ADM is 1/4. This is because ∆ADM is one of the four equal parts of the square ABCD.

b) The probability that the point selected at random lies in ∆ADM but not in ∆ADN is 1/8. This is because ∆ADM and ∆ADN are two of the four equal parts of the square ABCD, and the union of these two parts forms one quarter of the square. Hence, the probability of the point lying in one of these parts but not in the other is 1/8.

c) The probability that the point selected at random lies neither in ∆ADM nor in ∆ADN is 3/4. This is because the union of ∆ADM and ∆ADN forms one quarter of the square ABCD, while the remaining three quarters of the square lie outside of both ∆ADM and ∆ADN. Hence, the probability that the point lies outside of both these parts is 3/4.

A permutation of a set in mathematics is, broadly speaking, the rearrangement of its elements if the set already has an ordered structure into a sequence or linear order. The act or procedure of altering the linear order of an ordered set is referred to as a "permutation."

A permutation is a function that rearranges a set; it is not an arrangement in and of itself. It is a bijection from a set to itself. Permutations are the arrangements themselves, according to an older and more fundamental perspective. The terms active and passive are occasionally attached to the term permutation to distinguish between these two, but older terminology uses the terms replacements and permutations.

The product of three numbers is 12,295.

We are given that the sum of three numbers x, y, and z is 165, so we can write:

x + y + z = 165

We are also told that when the smallest number x is multiplied by 7, the result is n. So we can write:

x * 7 = n

It is also given that the value n is obtained by subtracting 9 from the largest number y, so we can write:

y - 9 = n

And that this number n also results by adding 9 to the third number z, so we can write:

z + 9 = n

We have 3 equations with 3 unknowns, we can use these equations to solve the problem.

From the equation x * 7 = n, we can substitute n = y-9, and we get:

x * 7 = y - 9

From the equation z + 9 = n, we can substitute n = y-9, and we get:

z + 9 = y - 9

Now we have 2 equations with 3 unknowns x,y,z.

To solve for the third unknown, we can use the equation x + y + z = 165 and substitute the values that we know from the previous equations:

x + (y - 9) + (z + 9) = 165

Solving for x we get:

x = (165 - (y-9) - (z+9)) = (165 - y + 9 - z - 9) = (165 - y - z + 18) = (183 - (y+z))

Now we can substitute this value into one of the previous equations:

(183 - (y+z)) * 7 = y - 9

Solving for y and z we get:

y = 95 and z = 71

And the product of the three numbers is:

x * y * z = (183 - (y+z)) * y * z = (183 - (95 +71)) * 95 * 71 = (183 - 166) * 95 * 71 = 17 * 95 * 71 = 12,295

Answer:

sixty-seven thousand ninety-two

since the angles are equal, the ratio between projection beam length and screen length must be the same.

so,

6.

24/14 = 48/x

48/28 = 48/x

x = 28

7.

besides the projection principle, we have a basic triangle situation :

the bisector of the angle W is also bisecting the opposing side YX. that means that this is an isoceles triangle (both legs are equally long).

therefore,

y = 4×sqrt(2)

Answer:

[tex]\textsf{6.} \quad x = 28[/tex]

[tex]\textsf{7.} \quad y = 4\sqrt{2}[/tex]

Step-by-step explanation:

An angle bisector is a line that divides an angle into two equal parts.

An angle bisector in a triangle divides the opposite side into two segments which are in the same proportion as the other two sides of the triangle.

Applying the Angle Bisector Theorem:

[tex]\implies \dfrac{UT}{TS}=\dfrac{VU}{VS}[/tex]

[tex]\implies \dfrac{x}{14}=\dfrac{48}{24}[/tex]

Cross multiply:

[tex]\implies 24 \cdot x=48 \cdot 14[/tex]

[tex]\implies 24x=672[/tex]

Divide both sides by 24:

[tex]\implies \dfrac{24x}{24}=\dfrac{672}{24}[/tex]

[tex]\implies x=28[/tex]

Applying the Angle Bisector Theorem:

[tex]\implies \dfrac{XZ}{ZY}=\dfrac{WX}{WY}[/tex]

[tex]\implies \dfrac{4}{4}=\dfrac{y}{4\sqrt{2}}[/tex]

Carry out the division on the left side:

[tex]\implies 1=\dfrac{y}{4\sqrt{2}}[/tex]

Multiply both sides by 4√2:

[tex]\implies 1\cdot 4\sqrt{2}=\dfrac{y}{4\sqrt{2}}\cdot 4\sqrt{2}[/tex]

Speed is what it means. the speed at which an object's location changes in any direction. The distance travelled in relation to the time it took to travel that distance is how speed is defined. Since speed simply has a direction and no magnitude, it is a scalar quantity.

Length of brick = 1(1/2) = 3/2

Speed of ant = 0.3 ft/sec

Answer:

16%

Step-by-step explanation:

1) Mean, u = 100 

standard deviation, o = 15

Score specified = x = 115

so, z-score = (x - u)/o

                   = (115 - 100)/15 = 1

From the probability standard normal distribution curve, 84.13% of the test scores falls within 1 SD (z score = 1), so, the percentage of test scores below 115 is 84.13%, so, for the percentage of test scores of 115 or higher = 100% - 84.13% = 16%.
