A point P os equi distant from R(-2,4) and S(6,-4) and its x co ordinate is twice its Y co ordinate find co ordinates of P
Answer: [tex]P(-4,-2)[/tex]
Step-by-step explanation: Distance between two points is calculated as
[tex]d=\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}[/tex]
Equidistant means the same distance, i.e., the distance between points P and R is equal to the distance between points P and S.
Suppose P's y-coordinate is a. If its x-coordinate is double, then
(x,y) = (2a,a)
Thus
[tex]\sqrt{(2a+2)^{2}+(a-4)^{2}} =\sqrt{(2a-6)^{2}+(a+4)^{2}}[/tex]
Solving
[tex]4a^{2}+8a+4+a^{2}-8a+16=4a^{2}-24a+36+a^{2}+8a+16[/tex]
[tex]5a^{2}+20=5a^{2}-16a+52[/tex]
[tex]-16a=32[/tex]
[tex]a=-2[/tex]
y-coordinate is [tex]-2[/tex], then x-ccordinate is
2a = 2(-2) = [tex]-4[/tex]
Coordinates of point P equidistant for R and S is [tex](-4,-2)[/tex].
Enter 2/5 and 1/3 as a pair of equivalent fractions with the least common denominator between the two fractions.
Answer:
2/5 = 6/15
1/3 = 5/15
Step-by-step explanation:
LCD of 5 and 3 is 15.
So 2/5 = 2*3/15 = 6/15
and
1/3 = 5*1 / 15 = 5/15

Which table and graph represent the equation y = 3X?
—————————
a.table B and graph A
b.table B and Graph B
c.table A and graph B
d.table A and graph A
Answer:
d. table A and graph A
Step-by-step explanation:
y=3x
y = 3X is represented by graph B .
y = 3X is represented by table A .
Hence option C is correct .
Given, Equation : y = 3X
Now, to get the values of y substitute x.
Firstly table A:
y = 3X
x = 1 : y = 3
x = 2 : y = 6
x = 3 : y = 9
Thus table A represents the equation .
Next graph B :
Starting point of graph B is origin.
Coordinates of origin : (0,0)
Equation of graph B : y = 3X
Thus graph B represents the equation .
Therefore option C is correct .

Drew has more than 4 times as many baseball cards as mark. Katie has fewer than half as many cards as mark. Mark has m baseball cards
Answer:
Cards with Mark = 30
Cards with Drew = 120
Cards with Katie = 12
Step-by-step explanation:
The complete question is
Drew has 4 times as many baseball cards as Mark. Katie has 3 fewer than than half as many cards as Mark. In all they have 162 baseball cards. How many does each have?
Solution -
Let the number of cards with Mark be "X"
Number of cards with Drew = 4 *X = 4X
Number of Cards with Katies = 0.5 X -3
Sum of all the cards is equal to 162
X+4X + 0.5 X -3 = 162
5.5 X = 165
X = 30
Cards with Mark = 30
Cards with Drew = 4 * 30 = 120
Cards with Katei = 15-3 = 12

Step-by-step explanation:
You conduct a simulation regarding students scores on a physics test. Your null hypothesis is
that the mean score on the test is less than or equal to 80 points. Your alternative hypothesis is
that the mean score is greater than 80 points.
You determine that the results of your simulation have a p-value of 0.06. What does this mean?
Under the tested hypothesis, the outcome of the simulation has a probability of 6%. With a significance level of 5%, you should FAIL to reject the null hypothesis.
The p-value is the probability of getting true null hypothesis.
What is Null Hypothesis and Alternative Hypothesis?Null hypothesis is a hypothesis of a test which assumes that there is no statistical relationship between two variables. This is the hypothesis which is being testes.
Alternative hypothesis assumes that there is a relationship between two variables.
Given that,
You conduct a simulation regarding students scores on a physics test.
Null hypothesis is that the mean score on the test is less than or equal to 80 points.
Alternative hypothesis is that the mean score is greater than 80 points.
p value = 0.06 = 6%
This means that there is only a 6% that the null hypothesis of yours is true.
So the p value tells you the probability of getting a true null hypothesis.
Hence the p value is the probability of getting true null hypothesis.

Han's family got a solar panel. Each month they get a credit to their account for the electricity that is generated by the solar panel. The credit they receive varies based on how sunny it is. In January they used $83.56 worth of electricity and generated $6.75 worth of electricity. Here is their electricity bill from January. Current charges: $83.56 Solar Credit: -$6.75 Amount due: $76.81 1) In July they were traveling away from home and only used $19.24 worth of electricity. Their solar panel generated $22.75 worth of electricity. What was their amount due in July?
Answer:
-$3.51
Step-by-step explanation:
Given that :
Current charges:
$83.56 Solar Credit: -$6.75
Amount due: $76.81
July they were traveling away from home and only used $19.24 worth of electricity. Their solar panel generated $22.75 worth of electricity. What was their amount due in July
Worth of electricity used in July = $19.24
Worth of electricity generated by solar = - $22.75
Electricity used in July + solar credit charge
$19.24 - $22.75
= -$3.51

Answer:
A+6+A = 20
A = 7
Step-by-step explanation:
J = number of problems Juana completed
A = number of problems Andy completed
J+A=20
J = A + 6
Replace J with A+6 in the first equation
A+6+A = 20
2A +6 = 20
Subtract 6 from each side
2A +6-6 = 20-6
2A =14
Divide by 2
2A/2 = 14/2
A = 7
Answer:
7
Step-by-step explanation:
set up your two equations.
j + a = 20. equation 1
j = a + 6. equation 2
since you know that j = a + 6, you can substitute a + 6 into the place of j. this is because you want to isolate a in order to find out how many problems andy completed.
j + a = 20
a + 6 + a = 20
now solve.
2a + 6 = 20
2a = 14
a = 7
andy has completed 7 problems. if juana completed 6 more than andy, then she has completed 13. 13 + 7 = 20.
