AlexFokin [52]

Answer:

19.38 Months, so 1.6 years

Step-by-step explanation:

6.5% compounded monthly is $325 a month (5,300*.065) so if you subtract 11,300-5,000 you get $6,300. You divide that by 325 and you get 19.38 (months) divide that by 12 months and you get 1.6 (years)

I need help now plz​
Romashka-Z-Leto [24]

Answer:

C

Step-by-step explanation:

The picture is a bit blurry, but from what i can see, i'd say C (whichever one has -4 x 3 x 1 under the square root.)

So for this, you need to know the quadratic formula, which is:

\frac{-b ± \sqrt{b^{2} -4ac} }{2a}

<em>*ignore the weird capital A, it keeps coming up when i try to use the ± symbol</em>

They have given you the equation of a quadratic, so the first thing you have to do is rearrange it, so that x^{2} comes first.

<u>So now we have the equation: 3</u>x^{2}<u> - 2x +1</u>

*the quadratic formula uses a, b and c, but they are specific. a is always the coefficient of x^{2} , b is always the coefficient of x and c is always the constant (number without an x)

<u>So, i can find that, in this case:</u>

a = 3      b= -2    c=1

<u>Now substitute each of those values it into the original quadratic equation:</u>

<u />

\frac{-(-2) ± \sqrt{(-2)^{2} -4(3)(1)} }{2(3)}

<em>*again, ignore the weird capital A. </em>

That's how you find the answer, which from what i can tell in the picture is C.

Hope that helped : )

"Use the following information to answer the question. The mean age of lead actresses from the top ten grossing movies of 2010 w
julia-pushkina [17]

Answer:

a) 10.6; 48.7; within

Step-by-step explanation:

The Empirical Rule states that, for a normally distributed random variable:

68% of the measures are within 1 standard deviation of the mean.

95% of the measures are within 2 standard deviation of the mean.

99.7% of the measures are within 3 standard deviations of the mean.

In this problem, we have that:

Mean = 29.6

Standard deviation = 6.35

"According to the Empirical Rule, the ages of nearly all lead actresses will be between______________and_____________ years.

Nearly all(99.7%) will be within 3 standard deviations from the mean.

So from 29.6 - 3*6.35 = 10.6 years to 29.6 + 3*6.35 = 48.7 years.

Anna was 11-years old, so she was within this range.

So the correct answer is

a) 10.6; 48.7; within
