Amanda's average grade on a set of five test was 88%. She can remember only that the first four grade were 78%, 86%, 96%, and 94%. What was the grade on her fifth test ?

Answer:

2/3 probability

Step-by-step explanation:

less than 5 is 4. There are 6 sides, so its 4/6. 4 out of 6 simplifies to 2/3.

Answer:

as there are 2 six-sided dices so total cases = 6*6 = 36

products less than 5 are = (1,1) , (1, 2), (1, 3), (2,1), (2,2), (3,1)

so number of products less than 5 = 6

so the probability = 6/36 = 1/6

Step-by-step explanation:

Answer:

[tex]y = - \frac{4}{5} x + \frac{6}{5} [/tex]

Step-by-step explanation:

First subtract 4x on both sides in order to get -5y alone. Now you have -5y = 4x + 6 (since neither 6 nor 4x are like terms). Now divide -5 on both sides in order to get rid of it, so we can get y by its self. Now you have y = -4/5 x + 6/5

Hope this makes sense. Also please tell me if I'm wrong and I'll be happy to look at it again for ya :)

Answer:

[tex]p=(12.75+7.25)/8[/tex]

Step-by-step explanation:

The money she earned is the remaining money plus the board game price. With the total profit, you divide by the 8 puzzles

Brittany received an amount of $2.50 for each puzzle in her collection.

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

Let's assume the amount of money Brittany received for each puzzle in her collection is p dollars.

Then the total amount of money she received for 8 puzzles will be 8p dollars.

If she used $7.25 to buy a board game, then the amount of money she had before purchasing the board game was 12.75 + 7.25 = $20.

We know that the total amount of money Brittany received for 8 puzzles was 8p dollars. So we can write an equation:

8p = 20

Divide both sides by 8:

p = 2.5

Therefore, he received $2.50 for each puzzle in her collection.

Answer:

  $6307.95

Step-by-step explanation:

The compound interest formula can help with that.

  A = P(1 +r/n)^(nt) . . . . value of principal P at rate r for t years, compounded n times per year.

  P = A(1 +r/n)^(-nt) = $8000(1 +0.04/2)^(-2·6) = $8000(1.02^-12) = $6307.95

Answer:

Banks play an important role in the economy by offering a service for people wishing to save. Banks also play an important role in offering finance to businesses that wish to invest and expand. These loans and business investment are important for enabling economic growth.

The financial services sector is the primary driver of a nation's economy. It provides the free flow of capital and liquidity in the marketplace. When the sector is strong, the economy grows, and companies in this industry are better able to manage risk.

log ( x^2/(yz^2))

Step-by-step explanation:

2 log x - log y - 2 log z

We know a log b = log b^a

Rewriting

2 log x = log x^2  and 2 log z = log z^2

log x^2 - log y -  log z^2

Rewriting

log x^2 - (log y +  log z^2)

We know that log a + log b = log (a*b)

log x^2 - (log (y z^2))

And we know log a - log b = log (a/b)

log ( x^2/(yz^2))

Answer:

[tex]log\frac{x^2}{yz^2}[/tex]

Step-by-step explanation:

Simplify 2log(x) by moving 2

inside the logarithm.

Simplify 2log(x) by moving 2

inside the logarithm.

log(x^2)−log(y)−2log(z)

Simplify −2log(z)

by moving 2

inside the logarithm.

log(x^2)−log(y)−log(z^2)

Use the quotient property of logarithms, logb (x)−logb (y)=logb (x/y)

[tex]log\frac{x^2}{y} - log(z^2)[/tex]

Use the quotient property of logarithms, logb(x)−logb(y)=logb (x/y)

[tex]log (\frac{x}{y})/( \frac{1}{z^2}}][/tex]

Multiply the numerator by the reciprocal of the denominator.

[tex]log\frac{x^2\\ }{y}.\frac{1}{z^2}[/tex]

Combine.

[tex]log\frac{x^2*1\\ }{yz^2}[/tex]

Multiply [tex]x^{2}[/tex] by 1

[tex]log\frac{x^2}{yz^2}[/tex]

Answer:

Step-by-step explanation:

xy = 864

x + y = 60                     Solve for y in the second equation

y = 60 - x                      

x * (60 - x) = 864          Remove the brackets.

60x - x^2 = 864           Put in order of powers and subtract 864

-x^2 + 60x - 864 =0    Multiply through by -1

x^2 - 60x + 864 = 0

This factors

(x - 36)(x - 24) = 0

Either

x - 36 = 0    in which case

x = 36

or

x - 24 = 0

x = 24

The two numbers are x = 36 and y = 24

of x = 24 and y = 36

The 75 exhibits are in the reptile house.

we have given that,

A volunteer at the zoo is responsible for feeding the animals in 15 exhibits in the reptile house.

We have to determine how many exhibits are in the reptile house.

Therefore we have

if 15 exhibits = 20% of total exhibits,

A percentage is a number or ratio expressed as a fraction of 100.

then 15/20% = 75 total exhibits in the reptile house

We can check the answer,

75 x 20% = 15

Therefore the 75 exhibits are in the reptile house.

[tex]y = x + \pi[/tex]

Step-by-step explanation:

We need to find the slope of the line tangent to y at [tex]x=-\pi[/tex] and we can do that by calculating the derivative of y at that point. We know that

[tex]y'(x) = \dfrac{d}{dx}(\tan{x}) = \sec^2{x}[/tex]

and

[tex]y'(-\pi) = \sec^2(-\pi) = 1[/tex]

To find the equation of the tangent line, we know that the line passes through the point [tex](-\pi, 0)[/tex] so we can write the slope-intercept form of the line's equation as

[tex]0 = (-\pi) + b \Rightarrow b = \pi[/tex]

Therefore, the equation of the line tangent to the point [tex]x = -\pi[/tex] is

[tex]y = x + \pi[/tex]
