Answer:

Step-by-step explanation:

7+5

Answer:

.

Step-by-step explanation:

The distance between two points (x1, y1) and (x2, y2) is given by the formula:

d = sqrt((x2 - x1)^2 + (y2 - y1)^2)

Here, (x1, y1) = (-7, 3) and (x2, y2) = (5, 3).

Substituting these values, we get:

d = sqrt((5 - (-7))^2 + (3 - 3)^2)

= sqrt((12)^2 + (0)^2)

= sqrt(144)

= 12

Therefore, the distance between (-7, 3) and (5, 3) is 12 units.

Therefore , the solution of the given problem of triangle  comes out to be segments LM and MN have equal 10x measures.

A triangle is a polygon because it has two or more additional parts. It has the simple form of a rectangle. A triangle can only be distinguished from a conventional triangle by its three sides, A, B, but not C. So when borders are still not exactly collinear, Euclidean geometry results in a single area as opposed to a cube. Three edges and three angles are the characteristics of triangles.

Here,

Given that RS and LM are the respective sides of the two triangles, if we set x as the length of RS, then LM's length is 5x and ST's length is 2x. The duration of MN is five times that of ST, which is ten times longer.

We can now calculate the length of RS using the tangent of angle R:

=> tan R=RS/ST

=> 5/2.5=2

We thus have:

=> RS = 2

=> ST = 2x

We can determine the length of RT using the Pythagorean theorem:

=> RT/ST = sin R

=> RT = ST sin R

=>  2.5 (2/29) = 4.337 sin R = 2.5

We can now determine the lengths of LM and MN using the similarity of the triangles:

=> RM = 5 (2x) LM = 5 = 10

=> MN = 5 ST = 5 (two times) = 10

As a result, segments LM and MN have equal 10x measures.

The values of LM = 12.5 and MN = 25

A triangle is a closed geometric figure consisting of three line segments or sides, connected to each other at three endpoints or vertices. Each side of a triangle intersects with exactly two other sides, and the vertices are the points where the sides meet.

From the given figures, both the triangles are right angle triangle.

[tex]tan R=\frac{5}{2.5} = \frac{ST}{RS}[/tex]

So, ST = 5 and RS = 2.5

Since, ΔRST is 5th to create ΔLMN,

its corresponding sides are 5 times the length LM corresponding sides of RS. So, its length

LM = 5×2.5 = 12.5

LM = 12.5

MN corresponding sides of ST. So, its length

MN = 5×5 = 25

MN = 25

Therefore, The values of LM = 12.5 and MN = 25.

Answer: To estimate the mean score for all the students in the district, we can use a confidence interval. We are given that the sample size is 400, the sample mean is 110, the population means is 100, and the population standard deviation is 15. We are asked to find a 99% confidence interval for the population mean.

The formula for a confidence interval for the population mean with known population standard deviation is:

Confidence interval = sample mean ± z*(σ/√n)

where:

sample mean = 110 (given)

σ = 15 (given)

n = 400 (given)

z = the critical value from the standard normal distribution for a 99% confidence level, which is 2.576.

Substituting the values, we get:

Confidence interval = 110 ± 2.576*(15/√400)

Confidence interval = 110 ± 1.92

Therefore, the 99% confidence interval for the population mean score is (110 - 1.92, 110 + 1.92), or (108.08, 111.92). We can be 99% confident that the true population mean score for all the students in the district falls between 108.08 and 111.92.

Answer:

the length of IJ is 7.2 units.

Step-by-step explanation:

Since IJ is parallel to LM, we can use the property of similar triangles to solve for IJ.

Triangles KIJ and KLM are similar, so we have:

IJ/KL = KI/LM

Substituting the given values, we get:

IJ/8 = 18/20

IJ/8 = 9/10

Multiplying both sides by 8, we get:

IJ = (8)(9/10)

IJ = 7.2

Therefore, the length of IJ is 7.2 units.

Answer:

Step-by-step explanation:

Let the age of the son be $s$ and the age of the father be $f$. From the first equation, we have $2s + f = 56$, and from the second equation, we have $f + 2s = 82$. Solving this system of equations, we get $s = 12$ and $f = 32$, so the son is 12 years old and the father is 32 years old.

Let the two-digit number be $10t+u$, where $t$ is the tens digit and $u$ is the units digit. We are given that $t+u=13$ and $2t-u=1$. Solving this system of equations, we get $t=7$ and $u=6$, so the two-digit number is $76$.

Let the two-digit number be $10x+y$, where $x$ is the tens digit and $y$ is the units digit. We are given that $2(10+x+y) = 27(10x+y)$, or $20+2x+2y = 270x+27y$. Simplifying this equation, we get $268x-25y = 10$. Since $y$ is a digit, we know that $0 \leq y \leq 9$. We can check that $x=1$ is too small, so we try $x=2$. Plugging in $x=2$, we get $536-25y=10$, which gives $y=21/5$, which is not a digit. Thus, there is no solution for a two-digit number.

A three-dimensional object's volume, which is expressed in cubic units, indicates how much space it takes up. The symbols cm3 and in3 are two examples of cubic measures. However, the bulk of an item may be employed to estimate its size. Usually, the weight of an item is converted into mass measures like grams and kilos.

The formula: gives the capacity of a pyramid.

=> V = (1/3)Bh

where B is the base's size and h is the pyramid's height.

The ratio of the volumes of the dilated pyramid to the initial pyramid is (1/4)3 = 1/64 if the scale factor of dilation is 1/4. In other terms, pyramid B's volume is 1/64 that of pyramid A's.

Let V(A) represent the pyramid A's volume. Then:

Thus, we can be 90% confident that the true proportion of men in the college is between 8.8% and 14.0%.

Percent, denoted by the symbol "%", is a way of expressing a number as a fraction of 100. For example, 50% is equivalent to the fraction 50/100, which can be simplified to 1/2. Percentages are commonly used to express ratios, proportions, or rates in various contexts such as finance, statistics, and everyday life. For instance, an interest rate of 3% means that for every $100 borrowed, the borrower will be charged $3 per year. Similarly, a score of 80% on an exam means that the student has answered 80 out of 100 questions correctly.

by the question.

To find the confidence interval of the true proportion of men in the college, we need to use the formula:

where p is the sample proportion (80/700 = 0.114), z is the z-score associated with the confidence level (90% in this case), and n is the sample size (700).

To find the z-score, we can use a standard normal distribution table or a calculator. For a 90% confidence level, the z-score is approximately 1.645.

Answer: Since the alloy is made up of 93.5 parts aluminum, 5 parts zinc, and 1.5 parts copper, we can express the weight of zinc and copper needed to make the alloy as a ratio to the weight of aluminum needed. Let x be the weight of aluminum needed in pounds, then we have:

Weight of aluminum: Weight of zinc: Weight of copper = 93.5: 5 : 1.5

We know that the foundry has 164 pounds of aluminum available, so we can substitute x = 164 into the above ratio and solve for the weights of zinc and copper:

164: Weight of zinc: Weight of copper = 93.5: 5 : 1.5

Cross-multiplying, we get:

164 × 5 = 93.5 × Weight of zinc

Weight of zinc = (164 × 5) / 93.5

Weight of zinc = 8.76 pounds (rounded to two decimal places)

Similarly, cross-multiplying the above ratio gives us:

164: Weight of zinc: Weight of copper = 93.5: 5 : 1.5

164 × 1.5 = 93.5 × Weight of copper

Weight of copper = (164 × 1.5) / 93.5

Weight of copper = 2.63 pounds (rounded to two decimal places)

Therefore, the weight of zinc needed to make the alloy is 8.76 pounds and the weight of copper needed is 2.63 pounds.
