Answer:
The answer is option C
Step-by-step explanation:
x² - 7x + 10
To factor the expression rewrite - 7x as a difference
That's
x² - 5x - 2x + 10
<u>Factor out x from the expression</u>
x( x - 5) - 2x + 10
<u>Factor - 2 from the expression</u>
x(x - 5) - 2( x - 5)
Factor out x - 5 from the expression
The final answer is
<h3>( x - 2)(x - 5)</h3>

Answer:
y = −4x + 2
Step-by-step explanation:
The slope intercept form of the equation for a line is ...
y = mx + b . . . . . . where m is the slope and b is the y-intercept (0, b)
Here, you are given a slope of -4 (m=-4) and a y-intercept of (0, 2), so b=2. When you put these values in place of the corresponding variables, you get ...
y = -4x +2
Answer:
a) P(X=41)= 0.0086 = 0.86%
b) P(36≤X≤38)== 0.1215 = 12.15%
c) would be unusual that fewer that 20 murders were cleared because P(X≤20) = 0.000081 =0.0081%
Step-by-step explanation:
if the random variable X= number of cleared murders , then X follows a binomial distribution:
P(X=x)= n!/[(n-x)!*x!]*p^x*(1-p)^(n-x)
where P(X=x)= probability of x cleared murders, n= number of murders selected=50 , p= probability for a murder to be cleared (67%)
therefore
a) P(X=41)=50!/[(50-41)!*41!]*0.67^41*0.33^(50-41)= 0.0086
b) P(36≤X≤38)= P(X≤38) - P(X≤36) = 0.9371- 0.8156 = 0.1215
c) P(X≤20) = 0.000081
therefore would be unusual that fewer that 20 murders were cleared
