Answer:
There are 2 complex roots:
3 - 4i, 3 + 4i.
Step-by-step explanation:
x^2 - 6x + 25 = 0
Using the quadratic formula:
x = [-(-6) ± √(-6)^2 - 4*1*25)] / 2
= (6 ± √-64)/2
= 3 ± 8i/2
= 3 ± 4i
Answer:
X=42
Step-by-step explanation:
when the question says that ABCD ~ EFGH that's just saying that they are equal.
AB = 16 FE = 10 the first shape has sides that are 6 longer than the second shape.
next, to find X in FG, it's going to be BC - 6 = X - 4 = FG (aka 30 - 6 = 42 - 4 = 20).
i hope thought this out right for you, and hope that helps. :)
Answer:
2
Step-by-step explanation:
Mean = sum of data/sample size
Sum of data = 22 + 18 + 2y+1 + 10 + 20
Sample size = 5
Mean = 15
Substitute
15 = 22 + 18 + 2y+1 + 10 + 20/5
15*5 = 22 + 18 + 2y+1 + 10 + 20
75 = 70+2y+1
2y = 75-71
2y = 4
y = 4/2
y = 2
Hence the value of y is 2
A.the scale factor is negative
I took the test
The value of for x = 5 is 0.06
<h3>How to solve the probability?</h3>
The expression is given as:
This means that:
n = 10
p = 0.75
The probability is then calculated as
This gives
Evaluate the combination expression
Evaluate
P(5)= 0.06
Hence, the value of for x = 5 is 0.06
