Answer:
-1 and -2
Step-by-step explanation:
f(x) = 4x² − 8kx + 8x −9
f(x) = 4x² − 8(k−1)x − 9
If one root of f(x) is the opposite of the other, then f(x) must be a difference of squares, which means -8(k−1) = 0.
-8(k−1) = 0
k = 1
Therefore, the other polynomial is:
x² + 3x + 2
(x + 1) (x + 2)
The zeros are -1 and -2.
Answer:
2 fifths 2/5
Step-by-step explanation:
10 sided dice has 10 possibilities so 7 8 9 10 are even or greater than 7 that's 4 out of 10 numbers but in simplest form would be 2/5 (2 fifths)
Answer:
7 goldfish
Step-by-step explanation:
10-3=7
Answer:
0.952
Step-by-step explanation:
we know that
here standard error =std deviation÷(n)^1/2
=15/(25)^1/2 =15/5=3
Assuming that IQ scores are normally distributed
Now, probability of a Type II error
=P(X<110) = P(Z<(110-105)/3)=P(Z<1.67)
=0.952
the power of the test if the true population mean is 105 = 0.952

We have: 0.034 and 3.40
Required
The relationship between them
3.40 can be expressed as:
This means that 3.40 is 100 of 0.034
Similarly, 0.034 can be expressed as:
This means that 0.034 is 1/100 of 3.40
