For what values of h and k does the linear system have infinitely many solutions? 2x1 + 5x2 = −1 hx1 + kx2 = 7
Answer:
The values of [tex]h[/tex] and [tex]k[/tex] for a linear system with infinitely many solutions are -2 and 5, respectively.
Step-by-step explanation:
Let [tex]2\cdot x_{1}+5\cdot x_{2} = -1\cdot h\cdot x_{1} + k\cdot x_{2} = 7[/tex], if this linear system has infinitely many solutions, then the following conditions must be met:
[tex]-1\cdot h = 2[/tex] and [tex]k = 5[/tex].
[tex]h = -2[/tex] and [tex]k = 5[/tex]
The values of [tex]h[/tex] and [tex]k[/tex] for a linear system with infinitely many solutions are -2 and 5, respectively.

A medical device company knows that 11% of patients experience injection-site reactions with the current needle. If 3 people receive injections with this type of needle, what is the probability that the first person has an injection-site reaction, but the next two do not?
Answer:
0871
Step-by-step explanation:
Using geometric distribution, the probability that the first person has an injection-site reaction, but the next two do not is 0.087131.
What is geometric distribution?Geometric distribution is "a discrete probability distribution that represents the probability number of successive failure before a success obtained in a Bernoulli trial".
According to the question,
Patients experience injection-site reactions with current needle is 11%.
Number of people receive injections with this type of needle is 3.
The probability mass function of Geometric distribution (PMF) is given as
[tex]P(1 - p)^(x-1)[/tex].
P = 11 % = 0.11
In order to find the probability that the first person has an injection-site reaction, but the next two do not
= [tex]0.11(1-0.11)^(3-1)[/tex]
= [tex]0.11(0.89)^2[/tex]
=0.11(0.7921)
=0.087131
Hence, using geometric distribution, the probability that the first person has an injection-site reaction, but the next two do not is 0.087131.

Kayla used 4 isosceles triangles and one square to build a pyramid each edge of the square was 10 inches the two congruent sides of the triangles are 13 inches long the slant height of the triangles is 12 inches why is the surface area of a figure
Kayla constructed a square pyramid.
The area of the square is 10*10 = 100.
The area of each of the triangles are 12*5/2 = 30.
In total, we get 30*4 + 100 = 220.

Is x = –4 a valid solution this linear equation?
2x + 9(x – 1) = 8(2x + 2) – 5
Answer:
Yes it is!
Step-by-step explanation:
All you have to do is plug in -4 in place of all the x’s. You should get
-8x - 36 - 9 = -64x + 16 - 5
Simplified: -8x - 45 = -64x + 11
+45. + 45
-8x = -64x + 56
+64 +64
56 = 56
Answer = True
So yes -4 is a correct solution!
