Two symptoms are associated with a certain disease. There is a 95% probability that at least one of the symptoms occurs; in addi

tion, the first symptom occurs with 50% probability, the second symptom occurs with 45% probability. Based on these probability results, answer the following two questions 1) Are the two events "first symptom occurs" and "second symptom occurs" mutually exclusive (i.e. disjoint)? 2) Are the two events "first symptom occurs" and "second symptom occurs" independent? For each question, clearly state YES or NO and provide a brief written explanation that includes the appropriate numerical support.

Write the equation of the line that passes through the point (-2,-3) and has a slope of 5.
kolezko [41]

Answer: y=5x+7

Step-by-step explanation:

Since we are given the slope, all we have to do is plug in the given point and solve for the y-intercept.

-3=5(-2)+b             [multiply]

-3=-10+b                [add both sides by 10]

b=7

Now, we know the equation is y=5x+7.

Please help, don’t understand. For #14 what would the input of the function be?
Goryan [66]

a)

h(t) , namely "h" variable is being represented in terms of "t".

h = dependent variable, depends on the value of "t", output.

t = independent variable, takes on values freely, input.


b)

\bf \stackrel{\stackrel{h(t)}{t=1.4}}{h(1.4)} = \stackrel{h=12.8}{12.8}~~ \begin{cases} t=1.4~~&\textit{after 1.4 seconds}\\ h=12.8~~&\textit{the ball is 12.8 meters up} \end{cases}


c)

\bf h(2)=-5(2)^2+14(2)+3\implies h(2)=-20+28+3\implies h(2)=11

after 2 seconds, the ball is 11 meters high up.

Step-by-step explanation:

Using proportion,

If Out of 550 calculators = 6 are defective,

Then out of 12000 calculators = ? are defective

\frac{12000 calculators}{550calculators} * 6

= 21.8 * 6

= 130.8 ≈ 131

∴ Approximately 131 calculators are defective
