Answer:

-2x + 3y + 4 = 0

Step-by-step explanation:

ax + by + c = 0 if a = -2, b = 3, c = 4

Just replace the letters with numbers :)

-2x + 3y + 4 = 0

Enter the patriot equivalent to Tan (A) <br><br> And<br><br> Enter the ratio equivalent to cos (B)

PolarNik [594]

Answer:

$(a)\ \tan A = \frac{5}{12}$

$(b)\ \cos B = \frac{5}{13}$

Step-by-step explanation:

Given

See attachment for triangles

Solving (a)

$\tan(A)$

The tan of an angle is:

$\tan(\theta) = \frac{Opposite}{Adjacent}$

From the given triangle.

$Opposite = 5$

$Adjacent = 12$

So, we have:

$\tan A = \frac{5}{12}$

Solving (b)

$\cos(B)$

The cos of an angle is:

$\cos(\theta) = \frac{Adjacent}{Hypotenuse}$

From the given triangle.

$Adjacent = 5$

$Hypotenuse = 13$

So, we have:

$\cos B = \frac{5}{13}$

A random sample of size 100 was taken from a population. A 94% confidence interval to estimate the mean of the population was co

Firlakuza [10]

Answer:

Step-by-step explanation:

1) The z value was determined using a normal distribution table. From the normal distribution table, the corresponding z value for a 94% confidence interval is 1.88

The correct option is D

2) if 70% of all internet users experience e-mail fraud. It means that probability of success, p

p = 70/100 = 0.7

q = 1 - p = 1 - 0.7 = 0.3

n = number of selected users = 50

Mean, u = np = 50×0.7 = 35

Standard deviation, u = √npq = √50×0.7×0.3 = 3.24

x = number of internet users

The formula for normal distribution is expressed as

z = (x - u)/s

We want to determine the probability that no more than 25 were victims of e-mail fraud. It is expressed as

P(x lesser than or equal to 25)

The z value will be

z = (25- 35)/3.24 = - 10/3.24 = -3.09

Looking at the normal distribution table, the corresponding z score is 0.001

P(x lesser than or equal to 25) = 0.001

In 25 minutes, Jay can run 10 laps around the track. Write an equation to represent the relationship.

Inessa [10]

Answer:

The equation is $y=\frac{2}{5} x$ .

Step-by-step explanation:

Let $y$ represent the number of laps Jay run, and $x$ the number of minutes it takes him to run those laps.

We know that it it takes Jay 25 minutes to run 10 laps; therefore, the number of laps jay runs per minute is:

$\frac{10\:laps}{25\:minutes} =\frac{2}{5}\:laps/min$

So, if Jay runs for $x$ minutes, the number of laps $y$ he will run be:

$\boxed{y=\frac{2}{5}x}$
