Quadrilateral PQRS (shown below) is an isosceles trapezoid. If RP = 12, then SQ = ?
Answer: SQ = 12
Step-by-step explanation: A trapezoid is a quadrilateral with two opposite parallel sides, called bases. The trapezoid is an isosceles trapezoid when the non-parallel sides have the same length.
One property of isosceles trapezoid is that its diagonals are congruent, i.e., have the same length.
In the picture, segment RP is one of the trapezoid's diagonal. It is asking the measure of SQ, which is the other diagonal. So:
SQ = RP
SQ = 12
Segment SQ of isosceles trapezoid PQRS is 12 units.
Answer:
if quadrilateral PQRS is an isosceles trapezoid if RP=12 then SQ= 12

Answer:
x = 30
Step-by-step explanation:
well the two agnles are congruent so they have to equal the same angle
x+ 90 = 4x
solve for x bye subtracting x from 90
90 = 3x slove by dividing 90 by 3 getting x alone
90/3 = x
a hungry statistician analyzed nutritional information from 77 food items available for purchase at a popular coffee shop (seattle's worst). the statistician produces a multiple regression model with response variable calories, and three predictors.
For given regression model, the number 59.89 in the table tells us that for every food item which is sandwich there is a corresponding 59.89-unit increase in Calories.
In this question we have been given a summary of regression model.
We need to explain the meaning of the number 59.89 in the table.
For given regression model, to view the results of the model, we can use the summary() function in R programming.
In given summary consider the 'Coefficients' table.
The first row gives the estimates of the y-intercept, and the second row gives the regression coefficient of the model.
The 'Estimate' column is the estimated effect, also called the regression coefficient or r² value.
The number 59.89 in the table is coefficient for IsSandwich.
This number tells us that for every food item which is sandwich there is a corresponding 59.89-unit increase in Calories.
Therefore, the meaning of the number 59.89 in the table: for every food item which is sandwich there is a corresponding 59.89-unit increase in Calories.

if sin a = 7/25, cos a = 24/25, sin b = 3/5 and cos b= 4/5, find cos (a-b)
Answer:
\(cos(a-b) = \frac{117}{125}\)
Step-by-step explanation:
Explanation
Given that
\(sina = \frac{7}{25} , cos a = \frac{24}{25} , sinb =\frac{3}{5} and cosb =\frac{4}{5}\)
Cos(a-b) = cosa cosb + sina sinb
\(cos(a-b) = \frac{24}{25} \frac{4}{5} +\frac{7}{25} \frac{3}{5}\)
\(cos(a-b) = \frac{96}{125} +\frac{21}{125} = \frac{117}{125}\)
Final answer:-
\(cos(a-b) = \frac{117}{125}\)

Rae leaves a party and heads north
walking at 2 km/hr. Dana leaves the same
party one hour later and heads south at
pace of 3 km/hr. How many hours will it
take the friends to put 7 km between
them?
The required it will take 2 hours for the friends to put 7 km between them.
What are equation models?The equation model is defined as the model of the given situation in the form of an equation using variables and constants.
Let's call the number of hours it takes the friends to be "x". During that time, Rae will have traveled 2x km. And Dana will have traveled 3(x-1) km (since she left an hour later).
We can now set up an equation:
2x + 3(x-1) = 7
Expanding the second term:
2x + 3x - 3 = 7
Combining like terms:
5x - 3 = 7
Adding 3 to both sides:
5x = 10
Finally, dividing both sides by 5:
x = 2
So it will take 2 hours for the friends to put 7 km between them.

Step-by-step explanation:
Find the path of a heat-seeking particle placed at point P on a metal plate with a temperature field T(x,y). Temperature Field: T(x,y)= 100 - x^(2) - 2y^(2).
As a result, the following parametric equations describe the motion of the heat-seeking particle: x = a - 2t and y = b - 4t
As per the question given,
To find the path of a heat-seeking particle placed at point P on a metal plate with a temperature field T(x,y) = 100 - x^(2) - 2y^(2), we need to use the gradient vector of T(x,y).
The gradient of T(x,y) is given by:
∇T(x,y) = (-2x, -4y)
The heat-seeking particle moves in the direction of maximum increase of temperature, so it moves in the direction of the gradient vector, that is, (-2x, -4y).
To find the path of the particle, we need to integrate the gradient vector starting at point P = (a,b), where a and b are the coordinates of the point on the metal plate where the particle is placed.
So the path of the heat-seeking particle is given by the following parametric equations:
x = a - 2t
y = b - 4t
where t is the parameter that represents time.
These equations represent a straight line in the direction of the gradient vector of T(x,y). The particle moves from point P in the direction of the gradient vector, with a speed proportional to the magnitude of the gradient vector.

Answer:
x < - 2Step-by-step explanation:
\(-8x - 10 > 7x + 20\)
First subtract 7x from both sides of the inequality
That's
\( - 8x - 7x - 10 > 7x - 7x + 20 \\ - 15x - 10 > 20\)
Add 10 to both sides of the inequality
\( - 15x + 1 0 - 10 > 20 + 10 \\ - 15x > 30\)
Divide both sides by - 15
\( \frac{ - 15x}{ - 15} > - \frac{30}{15} \)

Answer:
\(\textsf{Choice A } \quad y = \dfrac{5}{3}x + 1\)
Step-by-step explanation:
Slope intercept form of a line equation is
y = mx + b
where
m = slope
b = y-intercept
A perpendicular line to y = mx + b will have a slope of -1/m
Let's first find the equation for line z in slope-intercept form
Slope m for a line = (y2- y1)/(x2 - x1) where x1, y1 and x2, y2 are two points on the line
Slope of line z is
\(m = \dfrac { 2 - (-1) }{-2 - 3} = \dfrac{3}{-5} = - \dfrac{3}{5}\)
So line z will have an equation of the form
\(y = -\dfrac{3}{5}x + b\)
We know that a line perpendicular to this line will have a slope of
\(- \dfrac{1}{-\dfrac{3}{5}} = \dfrac{5}{3}\)
So the equation of the perpendicular line is
\(y = \dfrac{5}{3}x + b\)
Only one of the 4 choices, name choice A has this slope of 5/3
Therefore the correct answer choice is A
There is no need to compute b, the y intercept but if you wanted to, this is how you would do it:
The perpendicular line passes through (3, 6). This means when x = 3, y =6
Substitute these values of x, y into the equation for the perpendicular line and solve for b
\(y = \dfrac{5}{3}x + b\\\\\text{When x = 3, y = 6}:\\\\6 = \dfrac{5}{3} \cdot 3 + b\\\\6 = 5 + b\\\\b = 6 - 5 = 1\\\\\text{So, the equation of the perpendicular line is }\\y = \dfrac{5}{3}x + 1\)
This corresponds to Choice A

What percentage of lottery winners are 70 years or older? % What is the relative frequency of ages under 40? What is the cumulative relative frequency of lottery winners younger than 50?
Answer and Step-by-step explanation:
a. The computation of the frequency of lottery winners from 19 age to 40 age is
Given that
From [20,29] , the frequency is 3
And, from [30,39] , the frequency is 10
So, the total frequency is 13
b. The percentage of lottery winners who has 70 years or older is
Here we considered the relative frequency
= 0.1 + 0.0333
= 0.1333
= 13.33%
c. The relative frequency of ages under 40 is
= 0.1 + 0.3333
= 0.43333
= 43.33%
d. The cumulative relative frequency younger than 50 is
= 0.1 + 0.3333 + 0.0667
