In which of the following ways are linear systems similar to quadratic systems? Select all that apply.
alex41 [277]

The <em>correct answers</em> are:


A) Both can be solved by graphing;

C) Both can be solved by substitution; and

D) Both have solutions at the points of intersection.


Explanation:


Just as a system of linear equations can be solved by graphing, a system of quadratic equations can as well. We graph both equations. We then look for the intersection points of the graphs; these intersection points will be the solutions to the system.


We can also solve the system by substitution. If we can get one variable isolated, we can substitute this into the other equation to solve.

.   Multiply (x + 3)(x – 3).
konstantin123 [22]
X × x = x^2
x × -3 = -3x
3 × x = 3x
3 × -3 = -9

x^2 + 3x - 3x - 9
So I would agree with C because the -3x and the 3x cancel each other out. I hope this helps!

The life expectancy in the US is 75 with a standard deviation of 7 years. A random sample of 49 individuals is selected. What is
victus00 [196]

Answer:

0.02275

Step-by-step explanation:

We use this z score formula to solve for this question

z-score is is z = (x-μ)/σ/√n

where x is the raw score

μ is the population mean

σ is the population standard deviation

From the above question,

x = 77

μ = 75

σ = 7

number of samples = 49

Hence, the z score = 77 - 75/ (7/√49)

= 2/(7/7)

= 2/1

= 2

Hence, the z score = 2

Using the z table to find probability

P(x<77) = 0.97725

P(x>77) = 1 - P(x<77)

= 1 - 0.97725

= 0.02275

Therefore, the probability that the same mean will be larger than 77 years

is 0.02275
