If the mean is 87, that means the sum of the grades is 6*87= 522. If the lowest grade is dropped that leaves 5 grades with an averagve of 89. SO the sum of those 5 is 5*89= 445. To find the grade subtracted, you find the difference of theses sums which is 522-445= 77 which is your answer.

Hope it helps!

but could u show ur work for others if they need the solution

The question basically asks for the median of the data which is 2.

Hope it helps!

yes it definitely does

If four six-sided dice are rolled, then there are 6^4=1296 possible outcomes. Of those outcomes, the only way to get a prime number by multiplication is to have 3 of the numbers equal to 1 and the fourth number equal a prime. 

1, 1, 1, 2
1, 1, 1, 3
1, 1, 1, 5
1, 1, 2, 1
1, 1, 3, 1
1, 1, 5, 1
1, 2, 1, 1

1, 3, 1, 1
1, 5, 1, 1
2, 1, 1, 1
3, 1, 1, 1
5, 1, 1, 1

These are the 12 cases which means 12/1296=1/108 is your answer.

100 ( .50) (.70) =   $35

We know that 360 degrees is a full circle

Since \(\frac{72}{360}\) degrees of the circle's yellow

We can simplify that to \(\frac{1}{5}\)

One-fifth of the students favorite color is yellow

That means that \(10\) students favorite color is yellow

Hope this helps!!!

72 degress of a 360 degree circle are shaded. That equals 1/5. So 1/5 of the 50 students has yellow as their favorite color which makes 1/5*50= 10 students your answer.

Hope it helps!

yes it does thx both of u

We have 3 different combinations we can make

1.) White and Brown: \(4\cdot4=16\) ways

2.) Brown and Blue:\(4\cdot2=8\) ways

3.) White and Blue: \(4\cdot2=8\) ways

So if we add all of the ways we get \(16+8+8=32\) different ways

Hope this helps!

Welcome! 

Can you find the error? Hint: It's the value of k

If you don't realize, it is the second question answered.

hey thank u man i appreciate it

Thanks!

So of the 5 primes given in the other question, 41+12= 53, 47+12= 59, and 59+12= 71. Three out of the five primes when added to 12 equal another prime. So your answer is 3/5.

Hope it helps!

i posted a new question which is the same as this one but fixed

This question doesn't exactly make sense, F(X)=X^3=(7-2x^9). If there is anything wrong with the question could you please correct it?

Thanks!

This question is missing some  info.....

You are missing parts of your question. 

But... there are 5 primes 41, 43, 47, 53, and 59 between 40 and 60 inclusive, with this information, can you solve your problem?

This question is a little off... a power function by definition is in the form Y=X^N. Since it isn't in that form, I'm assuming you mean what is the degree of the function. The degree is the value of the highest exponent of the equation and in this case, it would be 8.

Hope it helps!

This is a correction nobody will care about but this question is in Algebra 1 not precalc.

If there are 5 bags of apples with 8 apples in each, that means that there are 5*8= 40 apples. Since there are 3 more apples next to the bags, then the answer is 40+3= 43 apples.

Hope it helps!
