Answer:
<h2>The probability is

+

+

.</h2>
Step-by-step explanation:
The probability of having high blood pressure is 17%.
We need to find the probability of 2 or fewer have high blood pressure.
Possibility 1: No one have high blood pressure.
The probability is
.
Possibility 2: Only one have high blood pressure.
The probability is
.
Possibility 3: 2 among the 10 have the high blood pressure.
.
Any of the possibilities can happen.
Hence, the required probability is
+
+
.
note that the zeroes should be x = 1 and x = - 2 not x = - 1 and x = 2
the factors are then ( x - 1 ) and (x + 2)
and x³ - 4x² - 7x + 10 = (x - 1 )(x + 2) = x² + x - 2
thus x² + x - 2 is a factor
dividing x³ - 4x² - 7x + 10 by x² + x - 2 gives x - 5
the third zero is x = 5
check : (5)³ -4(5)² - 7(5) + 10 = 125 - 100 - 35 + 10 = 0
Answer:
D
Step-by-step explanation:
Hey There!
To find the area of a rectangle we do length times width
17 is the width and 4 is the length
so area is equal to 17x4
17x4=68 so your answer would be D
Y = x + 5....so we sub in x + 5 for y in the other equation
4x + y = 20
4x + x + 5 = 20
5x + 5 = 20
5x = 20 - 5
5x = 15
x = 15/5
x = 3
y = x + 5
y = 3 + 5
y = 8
solution is (3,8)
