<h3>5 of the 6 vaccinated people will be protected from the virus</h3>
<em><u>Solution:</u></em>
Given that,
Suppose that a vaccine is 85% effective against the flu
You vaccinated 6 people
To find: Number of people you expect will be protected from the virus
From given,
85 % of 6 people are effective against the flu
Which means,
Thus, 5 of the 6 vaccinated people will be protected from the virus
2+1=3
I hope this helped! :)
To covert degrees Fahrenheit (F) to degrees Celsius (C) we use the equation C<span> = (</span>F<span> - 32) × 5/9</span> . To convert degrees Celsius (C) to degrees <span>Fahrenheit (F) we have to rewrite the equation.
First step: Divide both sides by 5/9. The equation would look like this:
</span>C(9/5) = (F - 32)
Second step: Add 32 on both sides.
32 + (9/5)C = F or F = <span>32 + (9/5)C</span>
Answer:
x = 1.47 or x = -7.47
Step-by-step explanation:
x²+6x+9=20
This is a quadratic equation
x²+6x+9-20=0
x²+6x-11=0
Step 1 : Write the quadratic formula
x = <u>-b±√b²-4(a)(c)</u>
2a
Step 2 : Substitute values in the formula
a = 1
b = 6
c = -11
x = <u>-6±√6²-4(1)(-11)</u>
2(1)
x = <u>-6±√80</u>
2
x = -3 + 2√5 or x = -3 - 2√5
x = 1.47 or x = -7.47
