8/9 = 8/9
1/8 x 9 =9/8
18/16 =9/8
16/18 = 8/9
1/18 x 16 = 8/9

Answer: 21.4

Step-by-step explanation:

Area of a triangle = (1.7 * 2)/2=1.7 m2

Area of a rectangle = 3 * 2 = 6 m2

There are four colors in a bag containing 500 plastic chips. It is known that 28% of the chips are green. On average, how many c
larisa86 [58]

Answer:

14

Step-by-step explanation:

Total number of chips = 500

Percentage of green chips = 28%

P(green chips) = 0.28

Expected number of green chips from a simple of 50

Sample size, n = 50

p of green chips = 0.28

Recall:

Mean, m = n*p

Expected number of green chips = 50 * 0.28 = 14

14 green chips

What are the zeros of the quadratic function f(x) = 2x2 + 8x – 3? x = –2 – and x = –2 + x = –2 – and x = –2 + x = 2 – and x = 2
Scorpion4ik [409]
The given quadratic function is:

f(x)=2 x^{2} +8x-3

The zeros of the quadratic functions also known as its roots can be found using the quadratic formula.

According to the quadratic formula:

x= \frac{-b+- \sqrt{ b^{2}-4ac } }{2a}
here,
b = coefficient of x-term
a = coefficient of x²-term
c = costant term

For given function:
a = 2
b = 8
c = - 3

Using these values in the formula, we get:

x= \frac{-8+- \sqrt{64-4(2)(-3)} }{2(2)} \\  \\ 
x= \frac{-8+- \sqrt{88} }{4} \\  \\ 
x= \frac{-8+-2 \sqrt{22}}{4} \\  \\ 
x= \frac{-4+- \sqrt{22} }{2} \\  \\ 
x= \frac{-4+ \sqrt{22} }{2}, x= \frac{-4- \sqrt{22} }{2}

Thus, these values of x are the zeros of the given quadratic function f(x)=2x²+8x-3
