Answer:
yes they both are wrong
Step-by-step explanation:
Center of the Circle is (h,I) which is (4,-3)
so h= 4 and k = -3
radius is 4 units (3+1)
Equation for circle
substitute all the values in this equation

Answer: The price of system at extreme electronics is $570 and the price of system at ultra electronics is $395.
Step-by-step explanation:
Let the price of the system at the ultra electronics be u
Let the price of the system at extreme electronics be e
According to question, we have
Now, using the substitution method, we will solve the above system of equations.
Now, put the value of u in the first equation :
Now, we put the value of u in the equation which is given by:
Hence, the price of system at extreme electronics is $570 and the price of system at ultra electronics is $395.
Answer:
Step-by-step explanation:
2x + 1 - 4x = 7x +5
First, take 7x to the left side.
2x + 1 - 4x - 7x = 5
Now take 1 to the right side.
2x - 4x - 7x = 5 - 1
Now combine like terms.
-2x - 7x = 4
-9x = 4
Now divide both sides by -9.
<u>x = - 4/9</u>
Answer:
AB =7 and CD = 7
BC =4 and AD =4
Step-by-step explanation:
A( 1,3)
B (1,10)
C (5,10)
D (5,3)
As we can see in the graph, the AB = CD and BC = AD
AB = the distance between the y points since the x values are the same
AB = 10-3 = 7
AB =7 and CD = 7
BC = the distance between the x points since the y values are the same
BC = 5-1 =4
BC =4 and AD =4
Answer:
a)
b) 0.75 = 75% probability that he makes no more than one of the shots
Step-by-step explanation:
We have these following probabilities:
64% = 0.64 probability that he misses both shots, that is, makes none of them.
11% = 0.11 probability that he makes one shot.
25% = 0.25 probability that he makes both shots.
a. Construct the appropriate probability distribution. (Round your answers to 2 decimal places.)
Binomial probability distribution, in which P(X = x) is the probability of making x shots. So
b. What is the probability that he makes no more than one of the shots? (Round your answer to 2 decimal places.)
0.75 = 75% probability that he makes no more than one of the shots
