1\dfrac{1}{2}  \text{hours} \longrightarrow 120 \text{miles}

<u>Find 1 hour:</u>
1\text{ hour} \longrightarrow 120 \div 1\dfrac{1}{2} \text{ miles}

1\text{ hour} \longrightarrow 120 \div \dfrac{3}{2} \text{ miles}

1\text{ hour} \longrightarrow 120 \times \dfrac{2}{3} \text{ miles}

1\text{ hour} \longrightarrow 80 \text{ miles}

<u>Find 6 hours:</u>
6\text{ hours} \longrightarrow 80 \times 6 \text{ miles}

6\text{ hours} \longrightarrow 480 \text{ miles}

The time it takes a student to walk from the dorm to the chemistry lab follows roughly a Normaldistribution with a mean of 20 mi
creativ13 [48]

Answer:

95.15%

Step-by-step explanation:

We have that the mean (m) is equal to 20, the standard deviation (sd) 3

They ask us for P (x <25)

For this, the first thing is to calculate z, which is given by the following equation:

z = (x - m) / sd

We have all these values, replacing we have:

z = (25 - 20) / (3)

z = 1.66

With the normal distribution table (attached), we have that at that value, the probability is:

P (z <1.66) = 0.9515

Which means that the probability that it arrives before 25 minutes is 95.15%

What is the value of c such that the line y=2x+3 is tangent to the parabola y=cx^2
satela [25.4K]

The value of c such that the line y = 2\cdot x + 3 is tangent to the parabola y = c\cdot x^{2} is -\frac{1}{3}.

If y = 2\cdot x + 3 is a line <em>tangent</em> to the parabola y = c\cdot x^{2}, then we must observe the following condition, that is, the slope of the line is equal to the <em>first</em> derivative of the parabola:

2\cdot c \cdot x = 2 (1)

Then, we have the following system of equations:

y = 2\cdot x + 3 (1)

y = c\cdot x^{2} (2)

c\cdot x = 1 (3)

Whose solution is shown below:

By (3):

c =\frac{1}{x}

(3) in (2):

y = x (4)

(4) in (1):

y = -3

x = -3

c = -\frac{1}{3}

The value of c such that the line y = 2\cdot x + 3 is tangent to the parabola y = c\cdot x^{2} is -\frac{1}{3}.

The equation p=100−4t represents the percent p of battery power remaining in an MP3 player after t hours.
fenix001 [56]

Answer:

Step-by-step explanation:

Here time (t) is the independent variable; power (p) is the dependent one.

The graph of p = 100 - 4t is a straight line with slope -4.  100 is the vertical intercept.  Battery power begins at 100 and steadily decreases after that.
