Answer:

  yes, ∆RST ~ ∆XYZ

Step-by-step explanation:

You want to know if ∆RST is similar to ∆XYZ when RS=6, ST=14, XY=9, YZ=21 and ∠S≅∠Y.

Two triangles are similar by the SAS theorem if corresponding sides have the same ratio, and the angles between them are congruent.

Corresponding sides are ...

  RS : XY = 6 : 9 = 2 : 3

  ST : YZ = 14 : 21 = 2 : 3 . . . . same ratio

The angles between them are ...

  ∠S, ∠Y . . . . . given as congruent

Corresponding sides have the same ratios, and the angles between them are congruent, so the triangles are similar.

How to interpret a standard deviation?

The term "standard deviation" (or "") refers to the degree of dispersion of the data from the mean.

            Data are grouped around the mean when the standard deviation is low, and are more dispersed when the standard deviation is high.

X = ∑x/n

   = 3 + 4 + 2 + 7 + 1/5

    = 20/5 = 4

s² = [∑(Xi - x)²/N-1]

   = (6-4)² + ( 4 - 4 )²+ ( 4 - 4 )² + ( 7 - 4 )² + ( 1 - 4 )²/5 - 1

    = 26/4

    = 6.50

3/5 is the quotient of these fractions in lowest form when 3/10 divides by 2/4

When two fractions are divided, the first fraction is multiplied by the second fraction's reciprocal. Finding the reciprocal of the second fraction and this can be obtained by reversing its numerator and denominator—is and then dividing the  fractions. Multiply the two numerators after that. Multiply the two denominators after that, After that we need to simplify the fraction to its lowest form.

so in order to find quotient when 3/10 is divided by 2/4 we get:

quotient = (3/10) / (2/4)

=> (3/10) * (4/2)

=> 12/20

so the quotient of this division is 12/20

now we have to find the lowest form of quotient

so gcd(12,20) = 4

where gcd is greatest common divisor

so lowest form of 12/24 = (12/4) / (20/4)

=> 3 /5

so lowest form of the quotient is 3/5

Therefore , squaring a number and taking the square root of a number  is an opposite operation as we can see in the following explanation.

A number's square root, which is the result of multiplication by itself, yields the original number. Some examples of exponents are squares and square roots. Imagine the number twenty five. Additionally, this can be expressed as expression of  5x5.

Here,

In order to square an integer, you must multiply it by itself.

The opposite of squaring a number is the act of getting the square root.

Calculating the side length of a square whose area is a certain number can be compared to finding the square root of that number.

For example: √25=  √5*5 = 5

Without spectacles, Witney Pete has a 5/10 chance of hitting the bullseye. Witney Pete could strike the bullseye with his spectacles 0.7 of the time. This likelihood is far higher than hitting the bullseye without glasses. the probability that Pete hits five or fewer of his next ten shots is approximately 2.487.

Generally, To find the probability that Pete hits five or fewer of his next ten shots, we need to find the probability that he hits exactly 0, 1, 2, 3, 4, or 5 bull's eyes.

The probability that Pete hits exactly k bull's eyes in n throws is given by the binomial distribution:

P(k bull's eyes in n throws) = (n choose k) * p^k * (1-p)^(n-k)

where p is the probability of hitting a bull's eye on a single throw and n choose k is the binomial coefficient, which is equal to n!/(k!(n-k)!).

Substituting the given values, we get:

P(0 bull's eyes in 10 throws) = (10 choose 0) * (0.7)^0 * (0.3)^10 = 0.028 P(1 bull's eyes in 10 throws) = (10 choose 1) * (0.7)^1 * (0.3)^9 = 0.189 P(2 bull's eyes in 10 throws) = (10 choose 2) * (0.7)^2 * (0.3)^8 = 0.462 P(3 bull's eyes in 10 throws) = (10 choose 3) * (0.7)^3 * (0.3)^7 = 0.605 P(4 bull's eyes in 10 throws) = (10 choose 4) * (0.7)^4 * (0.3)^6 = 0.501 P(5 bull's eyes in 10 throws) = (10 choose 5) * (0.7)^5 * (0.3)^5 = 0.302

The probability that Pete hits five or fewer bull's eyes in his next ten shots is the sum of the probabilities of hitting exactly 0, 1, 2, 3, 4, or 5 bull's eyes:

P(hitting 5 or fewer bull's eyes in 10 shots) = 0.028 + 0.189 + 0.462 + 0.605 + 0.501 + 0.302 = 2.487

Answer:

(1.5, -3)

Step-by-step explanation:

Both equations are in slope intercept form which means that:

for y = mx + b

m = slope

b = y-intercept

The slope can help us go from the y-intercept to the next point on the graph to make the line

For the equation

y = 2x - 6

the y-intercept is -6, so plot a point there.

The slope is 2 which means you will go up 2 then to the right by 1  to the next point on the graph.

Use the same process to find the line for y = -4x + 3, but you have to keep in mind that when the "m" value is negative, that means the line will point to the left of the graph instead of the right.

Once the lines are draw, the point where they intercept will be the solution.

In the following we make multiple not sum to the power

Answer:

3.82 km

Step-by-step explanation:

Assuming that the change in elevation is linear, we can calculate the elevation change per km traveled.  The known values are the start (0km) and the sign (3km).  The elevation gain over that interval is (0.95-9.0)km = 0.5km.  That was for an distance interval of  3km, so we can write:

(0.5km elevation gain)/(3km distance)

We can use this as a rate change and and use it in a linear equation to predict the elevation as a function of distance.

Let y be the elevation and x the distance, both in km.

y = (0.183)(x)+b, where b is the elevation at the start of the trail.  We can find b by using this equation and entering one of the two data points.  Lets use the elevation of 0.95m at 3km distance:

y = (0.183)(x)+b

0.95 = (0.183)(3)+b

b = 0.4km

The full equation is :

y = (0.1833)X + 0.4

Enter 1.1 km for y and calculate x, the distance to reach 1.1 km altitude.

1.1 = (0.1833)X + 0.4

X = 3.82 km

The notation f (x) = y means that the functional value at the point x is y.

In the notation f (x) = y, we understand that the value x is to be plugged in the function given to us (which is f here) which on solving gives y as the answer or solution 'y' of that function at a point x.

For example, let us consider the function f (x) = 2x + 3 = y

Then if we find f (2), then 2 will be plugged in the function 2x +3 such that

f (2) = 2(2) + 3 = 7,

which means that 7 is the functional value, 'y' at the point 2 which is considered as x.

Answer:3 and  10 and 3/10

Step-by-step explanation:

To determine whether an inequality represents a relationship of "greater than" or "less than" by looking at a graph, you can look at the direction of the solid line. If the line is pointing upwards towards the right, it represents a "greater than" relationship. If the line is pointing downwards towards the right, it represents a "less than" relationship.

For example, consider the graph of the inequality "y > x + 2." The points on the graph that satisfy this inequality are those that are above the line "y = x + 2." This line represents the values of y that are equal to x + 2. The points above the line are greater than the values on the line, so the inequality "y > x + 2" represents a "greater than" relationship.

On the other hand, consider the graph of the inequality "y < x + 2." The points on the graph that satisfy this inequality are those that are below the line "y = x + 2." This line represents the values of y that are equal to x + 2. The points below the line are less than the values on the line, so the inequality "y < x + 2" represents a "less than" relationship.
