\bf{Hey\ there!}

\bf{For:\ 4d

\bf{\underline{REVERSE}\ the\ equation:4d

\bf{First\ the\ term\ 3d\ on\ each\ of\ your\ sides!\downarrow}

\boxed{\boxed{\bf{Thus\ the\ answer\ is:d

\bf{For:8-3d>11}

\bf{\underline{REVERSE}\ the\ equation:-3d+8>11}

\bold{First\ you\ have\ to\ subtract\ by\ 8\ on\ your\ sides!\downarrow}

\bf{-3d+8-8>11-8}

\bf{Cancel:8-8\ because\ 8-8\ equals\ 0}

\bf{Keep:11-8\ because\ that\ helps\ us\ solve\ for\ our\ answer}

\bf{11-8=3}

\bf{New\ problem:-3d>3}

\bf{Divide\ each\ of\ your\ sides\ by\ -3}

\bf{\frac{-3d}{-3}>\frac{3}{-3}}

\bf{Cancel\ out:\frac{-3d}{-3}\ because\ it\ equals\ 1}

\bf{Keep:\frac{3}{-3}\ because\ it\ helps\ us\ solve\ for\ your\ answer}

\bf{\frac{3}{-3}=-1}

\boxed{\boxed{\bf{Thus\ your\ answer\ is:d

\bf{Good\ luck\ on\ your\ assignment\ and\ enjoy\ your\ day!}

Which function has a horizontal asymptote equal to 2?
Slav-nsk [51]

ANSWER

f(x) = 4( {3}^{x} ) + 2

EXPLANATION

The exponential function in the form

f(x) = a( {b}^{x} ) + c

has a horizontal asymptote of

y = c

The given exponential function is:

f(x) = 4( {3}^{x} ) + 2

The horizontal asymptote is therefore

y = 2

It is said that sufferers of a cold virus experience symptoms for 7 days. However, the amount of time is actually a normally dis
AlexFokin [52]

Answer:

a) 0.18% of cold sufferers experience fewer than 4 days of symptoms

b) 64.40% of cold sufferers experience symptoms for between 7 and 10 days.

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean \mu and standard deviation \sigma, the zscore of a measure X is given by:

Z = \frac{X - \mu}{\sigma}

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this problem, we have that:

\mu = 7.5, \sigma = 1.2

a. What proportion of cold sufferers experience fewer than 4 days of symptoms?

This is the pvalue of Z when X = 4. So

Z = \frac{X - \mu}{\sigma}

Z = \frac{4 - 7.5}{1.2}

Z = -2.92

Z = -2.92 has a pvalue of 0.0018.

So 0.18% of cold sufferers experience fewer than 4 days of symptoms.

b. What proportion of cold sufferers experience symptoms for between 7 and 10 days?

This is the pvalue of Z when X = 10 subtracted by the pvalue of Z when X = 7. So

X = 10

Z = \frac{X - \mu}{\sigma}

Z = \frac{10 - 7.5}{1.2}

Z = 2.08

Z = 2.08 has a pvalue of 0.9812.

X = 7

Z = \frac{X - \mu}{\sigma}

Z = \frac{7 - 7.5}{1.2}

Z = -0.42

Z = -0.42 has a pvalue of 0.3372.

So 0.9812 - 0.3372 = 0.644 = 64.40% of cold sufferers experience symptoms for between 7 and 10 days.

7x-6y=9<br> 5x+2y=19 Solve the system using elimination.
ikadub [295]

Step-by-step explanation:

multiply 5x+2y=19 by 3 youll get 15x+6y=57

eliminate y

7x-6y=9

<u>15x+6y=57</u><u> </u> +

22x=66

x=3

substitute x to 5x+2y=19

15+2y=19

2y=4

y=2
