Answer:

you owe $5

Step-by-step explanation:

65% wins means $65

35% losses means -$70

Answer:

You owe 5 cents.

Step-by-step explanation:

(the amount of money won)(the number of successful rolls)+(the amount of money lost)(the number of unsuccessful rolls)=expected value

65% of rolls are successful which means that  13/20 of the rolls are successful (simply convert to a fraction).

35% of the rolls are unsuccessful which means that 7/20 of the rolls are unsuccessful.

Using the equation above we can use,

(1)(13/20)+(-2)(7/20)

to find the expected value.

(1)(13/20)+(-2)(7/20)=0.05

Answer:

cost price of a table=$9000

profit%=20%

Let profit be x

to find profit use formula,

profit%=profit/cost price*100

20%=x/$9000*100

20*$9000=100x

$180000/100=x

$1800=x

Now to find selling prie os a table use formula,

cost price +profit

$9000+$1800

$91800

therefore selling price of a table is $91800

Step-by-step explanation:

An employee has a probability of 0.19706 to make between $70,000 and $80,000

Probability is the potential for an event to occur or occur, and it indicates the likelihood that a statement is true. It is a field of mathematics where the probabilities of experiments happening are computed. We can determine everything from the likelihood of getting heads or tails when tossing a coin to the likelihood of making a research error, for instance, using a probability. It's formula is = number of favorable outcomes/total number of outcomes

Let X be the annual salary of employees in a large company.

Given the mean salary is $65,000 and the standard deviation is $6,000, the probability of making between $70000 and 80000 can be calculated as:

[tex]P(70000 < X < 80000)[/tex] = [tex]P(\frac{70000 - 65000}{6000} < z < \frac{80000 - 65000}{6000} )[/tex]

[tex]P(0.833 < z < 2.5)[/tex]

= 0.99379 - 0.79673 (from normal distribution table)

= 0.19706

Hence, the probability that an employee makes between $70,000 and $80,000 is 0.19706

Answer:

[tex]f(x) = 63000(0.97)^x[/tex]

Step-by-step explanation:

Given

[tex]f(0) = 63000[/tex] ---x = 0, in 2012

[tex]f(5) = 54100[/tex] -- x = 5, in 2017

Required

Select all possible equations

Because there is a reduction in the population, as time increases; the rate must be less than 1.

An exponential function is represented as:

[tex]f(x) = ab^x[/tex]

Where

[tex]b = rate[/tex]

rate > 1 in options (a) and (b) i.e. 1.03

This implies that (a) and (b) cannot be true

For option (c), we have:

[tex]f(x) = 63000(0.97)^x[/tex]

Set x = 0

[tex]f(0) = 63000(0.97)^0 = 63000*1=63000\\[/tex]

Set x = 5

[tex]f(5) = 63000(0.97)^5 = 63000*0.8587=54098.1 \approx 54100[/tex]

This is true because the calculated values of f(0) and f(5) correspond to the given values

For option (d), we have:

[tex]f(x) = 52477(0.97)^x[/tex]

Set x = 0

[tex]f(0) = 52477(0.97)^0 - 52477* 1 = 52477[/tex]

This is false because the calculated value of f(0) does not correspond to the given value

For option (e), we have:

[tex]f(x) = 63000(0.97)^\frac{1}{5x}[/tex]

Set x = 0

[tex]f(0) = 63000(0.97)^\frac{1}{5*0} = 63000(0.97)^\frac{1}{0} =[/tex]undefined

This is false because the f(x) is not undefined at x = 0

For option (f), we have:

[tex]f(x) = 52477(0.97)^{5x[/tex]

Set x = 0

[tex]f(0) = 52477(0.97)^{5*0} = 52477(0.97)^0 =52477*1= 52477[/tex]

This is false because the calculated value of f(0) does not correspond to the given value

From the computations above, only (c) [tex]f(x) = 63000(0.97)^x[/tex] is true

Answer:

33.8

Step-by-step explanation:

a²+b²=c²

15²+b²=37²

225+b²=1369

-225     -225

b²=1144

√1144

b=33.8

The distance from the bottom of the ladder to the bottom of the building would be 33.8 foot.

If ABC is a triangle with AC as the hypotenuse and angle B with 90 degrees then we have:

|AC|^2 = |AB|^2 + |BC|^2    

where |AB| = length of line segment AB. (AB and BC are rest of the two sides of that triangle ABC, AC being the hypotenuse).

If you place a 37-foot ladder against the top of a 15-foot building.

Let BC be the distance from the bottom of the ladder to the bottom of the building.

[tex]|AC|^2 = |AB|^2 + |BC|^2 \\15^2+BC^2=37^2\\225 + BC^2=1369\\BC^2 = 1369 - 225\\\\BC^2 = 1144\\\\BC = 33.8[/tex]

Answer:

3 [tex]\frac{7}{8}[/tex]

Step-by-step explanation:

To find the largest number add the value of the range to the smallest number.

- 2 [tex]\frac{3}{8}[/tex] + 6 [tex]\frac{1}{4}[/tex] ( change to improper fractions )

= - [tex]\frac{19}{8}[/tex] + [tex]\frac{25}{4}[/tex]

= - [tex]\frac{19}{8}[/tex] + [tex]\frac{50}{8}[/tex]

= [tex]\frac{31}{8}[/tex]

= 3 [tex]\frac{7}{8}[/tex]

Answer:

50

Step-by-step explanation:

Alright, so two of the points are: (0,25) (1,75)

Now we line them up:

(0,25)

(1, 75)

And, 0 to 1 has "1" as a difference.

That'll go on the bottom.

25 to 75 has a "50" difference.

That goes on top.

And then we get the slope of 50.

Hope this helped! :)

Answer:

Slope = 50

Step-by-step explanation:

[tex]\frac{y2-y1}{x2-x1}[/tex]

125 - 75/2-1

125-75 = 50

Answer:

y-intercept is (0,5)

Step-by-step explanation:

When a graph passes through (0,a), that's y-intercept. y-intercept is a point on y-plane that a graph passes through.

For Ex. If a graph passes through (0,4) then the y-intercept would be (0,4).

But remember that it must be (0,a) for it to be y-intercept (Because it has to intersect the y-plane)

Answer:

When we have a point (x, y), the angle that defines this point in polar coordinates is given by:

Tan(θ) = y/x

In this case, we know that θ = 195°

Then replacing that, we get:

Tan(195°) = y/x

0.268 = y/x

Now, there is a problem, we have a single equation and two variables.

So we will get:

y = (0.268)*x

This equation defines all the possible values that x and y could take such the angle in standard position is 195°.

So we only can conclude that:

x and y have the same sign.

For a given value of x, the correspondent y-value is:

y =  (0.268)*x
