Find the graph to the equation below plz 20 POINTS
Answer:
the last one option 4
Step-by-step explanation:
Write a system of equations with the
solution (2, 1, 0).
The system of equations with the solution are 2x + y - z = 5, 5x - 3y + 4z = 7 and -6x -7y + 2z = -19.
What is a system of equations?A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.
Solution to this system will give us the solution to the considered equation.
Solution to an equation is finding values of the variable included in the considered equation for which the equation considered evaluates to be true.
The system of equations with the solution (2, 1, 0) is;
2x + y - z = 5
The system of equations with the solution (5, -3, 4) is;
5x - 3y + 4z = 7
The system of equations with the solution(-6 , -7, 2) is;
-6x -7y + 2z = -19
The complete question is
"Write a system of equations with the solution (2, 1, 0) is 5, (5, -3, 4) is 7 and (-6 , -7, 2) is -19."

You would burn about 200 calories by walking for 1 hour. About how many calories would you burn if you walk for 15 minutes? PLS HELP ME!!!
Answer:
50
Step-by-step explanation:
So first just sort the times, and the number of calories:
200 calories -> 1hr
x -> 15 mins
So an hour is 4 times the amount of 15 mins, so all you need to do is divide 200 by 4. The answer is 50

Answer:
[tex]-\frac{\sqrt{21}}{2}[/tex]
Step-by-step explanation:
ASTC (I use a sentence to memorize: All Students Take Calculus):
Q1 - All functions are positive
Q2 - Sine is positive (Cosecant is positive as well) (all others negative)
Q3 - Tangent is positive (Cotangent is positive as well) (all others negative)
Q4 - Cosine is positive (Secant is positive as well) (all others negative)
Applying ASTC:
Secant is negative, so it can't be in quadrant 1, and quadrant 4.
Quadrant 2 - Sine and Quadrant 3 - Tangent are left.
Cosecant is positive so it can't be in quadrant 3.
Therefore, angle x is in Quadrant 2 or QII
Secant is hypotenuse / adjacent
5 = hypotenuse (hypotenuse is never a negative number)
-2 = adjacent
use pythagorean theorem to solve for opposite (bc tan = opp / adj)

Find the interquartile range.
A. 3 - 3 = 0
B. 10 - 7 = 3
C. 7 - 3 = 4
D. 10 - 3 = 7
Answer:
C. 7 - 3 = 4
Step-by-step explanation:
Given
[tex]Dataset: 3, 3, 4, 5, 6, 7, 10[/tex]
Required
The IQR
The IQR is calculated using:
[tex]IQR = Q_3 - Q_1[/tex]
Where:
[tex]Q_3 \to[/tex] Median of the upper [tex]half[/tex]
[tex]Q_1 \to[/tex] Median of the lower [tex]half[/tex]
The dataset has 7 values, so the median is: (7 + 1)/2 =8/2 = 4th position.
Split to two, we have:
[tex]Lower \to 3, 3, 4[/tex]
[tex]Median \to 5[/tex]
[tex]Upper \to 6, 7, 10[/tex]
The lower half has 3 data; So, the median is the 2nd position.
Hence:
[tex]Q_1 = 3[/tex]
The upper half has 3 data; So, the median is the 2nd position.
Hence:
[tex]Q_3 = 7[/tex]
So, the IQR is:
[tex]IQR = Q_3 - Q_1[/tex]
[tex]IQR = 7 - 3[/tex]
[tex]IQR = 4[/tex]

Which statement best describes the association between variable X and variable Y?
Answer:
weak, negative association
Step-by-step explanation:
If variables have a strong association, the points will form a clear line/curve. Since the graph's points are scattered and fairly chaotic, we can say the association is weak.
Positive associations trend upwards and negative associations tend downwards. This graph seems to overall tend downwards, so we can say the association is negative.

( y- y1) = m(x - x1)
y - 8 = -7( x - 4)
y- 8 =-7x +28
y = -7x +36

The width of a rectangle measures (4d – 8) centimeters, and its length measures
(7d – 3) centimeters. Which expression represents the perimeter, in centimeters, of
the rectangle?
Answer:
(22d-22) cm
Step-by-step explanation:
perimeter= 2×(4d-8+7d-3)
= 2× (11d-11)
(22d - 22) cm
Answer:
(22d-22)cm
Step-by-step explanation:
Perimeter = 2 x (width + Length)
= 2 x [(4d – 8) + (7d – 3)]
= 2 x (11d-11)
= (22d-22)cm
Two fair dice are rolled. Determine the following probability

The probability that one number is a multiple of 3 and the other is a multiple of 5 is
For a given day, temperature can be recorded as hot, mild and cold while weather can be sunny or cloudy. The probability that the temperature is hot, mild and cold are .15, .55 and .30, respectively. Probability that the weather is sunny if the temperature is hot is .67, if the temperature is recorded mild is.36, and if the temperature is cold is.33. Show all the steps including identification of what formulas/properties you used. Points will be deducted from answers if only the final answer is provided.
(a) List all probabilities given in this problem, expressed in terms of events that you define.
(b) What is the probability that it is a sunny day?
(c) Given that the weather is sunny, what is the probability that the temperature is hot? mild? cold?
(d) Given that the weather is cloudy, what is the probability that the temperature is hot? mild? cold?
(e) Is the cloudy weather independent of hot weather?
Answer:
a) p(H) = 0.15
, p(M) = 0.55
, p(C) = 0.30,
p(S | H) i.e. sunny and hot = 0.67
P(c | H) i.e. cloudy and hot = 1 - 0.67 = 0.33
P( S | M) i.e. sunny and mild = 0.36
P(c | M) i.e. cloudy and mild = 1 - 0.36 = 0.64
P( S | C )i.e. sunny and cold = 0.33
P( c | C) = 1 - 0.33 = 0.67
b) ≈ 0.40
c) P ( H | S ) = 0.2513
P( M | S ) = 0.495
P(C | S) = 0.2475
d) P( H I c ) = 0.0825
Probability of mild and cloudy= 0.587
Probability of cold and cloudy = 0.335
e) No
Step-by-step explanation:
a) List All probabilities given in this problem
lets represent each condition with the first letter
Temperature : Hot ( H ) , mild ( M ) , cold ( C )
weather : Sunny ( S ) and cloudy ( c )
hence the probabilities are ;
p(H) = 0.15, p(M) = 0.55, p(C) = 0.30,
p(S | H) i.e. sunny and hot = 0.67
P(c | H) i.e. cloudy and hot = 1 - 0.67 = 0.33
P( S | M) i.e. sunny and mild = 0.36
P(c | M) i.e. cloudy and mild = 1 - 0.36 = 0.64
P( S | C )i.e. sunny and cold = 0.33
P( c | C) i.e. cloudy and cold = 1 - 0.33 = 0.67
b) probability of a sunny day
P ( s ) = P( H ) * P( S | H ) + P( M ) * P( S | M ) + P(C) * P( S | C)
= (0.15 * 0.67) + ( 0.55 * 0.36 ) + ( 0.30 * 0.33 )
= 0.3975 ≈ 0.40
c) Given the weather is sunny ( application of Bayes theorem = P(A and B) / P(B) )
P ( H | S ) = ( 0.15* 0.67 ) / 0.4
= 0.2513
P( M | S ) = 0.55 * 0.36 / 0.3975
= 0.198 / 0.4
= 0.495
P(C | S) = 0.3 * 0.33 / 0.4
= 0.099 = 0.2475
D) Given that the weather is cloudy
P( c ) = 1 - 0.4 = 0.6
P( H I c ) = ( 0.15*0.33) / 0.6
= 0.0825
Probability of mild and cloudy = (0.55*0.64) / 0.6 = 0.587
Probability of cold and cloudy = ( 0.30 * 0.67) / 0.6 = 0.335
e) The cloudy weather ( c ) is not Independent of the hot weather
because condition for independency ( P(c) x P( H ) = P( c and H) ) is not fulfilled.
