Answer:
9/32 or 0.28125
Step-by-step explanation:
8 parents and 4 teachers
There are 12 possible outcomes.
probability = # of favorable outcomes / # of possible outcomes
Let's do the teachers first.
There are 4 teachers, and we are finding the probability for 3 of them being picked.
Therefore,
P = 3/4
Now let's do the parents.
There are 8 parents, and we want 3.
Therefore,
P = 3/8
Now, we do [tex]\frac{3}{4} *\frac{3}{8} = \frac{9}{32}[/tex]
Therefore, the chance of 3 teachers and 3 parents being picked out of 4 teachers and 8 parents is 9/32, or in decimal form 0.28125.
Hope this helped!

Answer:
1,304,0006Step-by-step explanation:
You may recall that when you learned multiplication of decimals, there were two facts involved:
the total number of decimal digits when two decimal numbers are multiplied is the sum of the numbers of decimal digits in each onemultiplying by 10 adds a zero on the right. (Multiplying by 10^n adds n zeros on the right.)__
Here, we combine these facts.
Multiplying the decimal number 1.304 by 1000000 will add 6 zeros to the right of 1304 to make it 1304000000. Placing the decimal point in this product so there are 3 decimal digits (as there are in 1.304) makes this number be ...
1,304,000.000 . . . . . . product of 1.304 and 1,000,000
You will notice the decimal point in 1.304 has effectively moved 6 places to the right.
Arrange these numbers in order from least to greatest.

jacob said the product of 8/9 and 2 and 3/4 is 3 and 1/4. how can you tell that his answer is wrong?
Answer:
he is wrong becuase 89 times a number greater than 0 cannot result in a product greater than the number
Step-by-step explanation:
Based on real algebra properties, we know that the product of 8/9 and 2 and 3/4 is not 3 and 1/4.
How to infer the correctness of a product?The multiplication of two positive integers equals another positive integer. Each term of a multiplication can be rewritten as sums of multiples of 10, which can be simplified by algebra:
Given; Definition of multiplication
8/9 and 2 = 26/9
3/4
The product is;
26/9 x 3/4
= 13 x 1/6
= 13/6
Based on real algebra properties, we know that the product of 8/9 and 2 and 3/4 is not 3 and 1/4.

Answer:
pretty sure it's 10 1/2
Answer:
I think the answer is D. 12 1/2
Step-by-step explanation:
If you add up the two thing it becomes: 15 cups of flour and 6 cups of milk. So if you divide 15 by 6, it's 2.5. Now all you have to do is 5 (since there are 5 cups of milk) times 2.5, and you get 12.5. And 12.5 is 12 1/2 in fraction form. Hence, the answer is D. 12 1/2.

What question?
Step-by-step explanation:
What is the equation written in vertex form of a parabola with a vertex of (9, -1) that passes through (7. 7)?
O
A. y = 2(x - 992 - 1
B. y = 2(x + 1)2 - 9
O C. y = 2(x - 7)2 + 7
D. y = 7(x - 9)2 - 1
Answer:
[tex]y = 2\, (x - 9)^{2} - 1[/tex].
Step-by-step explanation:
If the vertex of a parabola is [tex](h,\, k)[/tex], there would exist a constant [tex]a[/tex] ([tex]a \ne 0[/tex]) such that the following would be an equation for this parabola:
[tex]y = a\, (x - h)^{2} + k[/tex].
The equation above is in the vertex form.
In this question, the vertex of this parabola is [tex](9,\, -1)[/tex]. (Such that [tex]h = 9[/tex] and [tex]k = -1[/tex].) Therefore, the equation of this parabola in the vertex form would be:
[tex]\text{$y = a\, (x - 9)^{2} + (-1)$ for some $a \ne 0$}[/tex].
It was also given that the point [tex](7,\, 7)[/tex] is on the parabola. In other words, if [tex]x = 7[/tex] and [tex]y = 7[/tex], the equation of this parabola ([tex]\text{$y = a\, (x - 9)^{2} + (-1)$}[/tex]) should be satisfied. In other words:
[tex]7= a\, (7 - 9)^{2} + (-1)[/tex].
Solve this equation for [tex]a[/tex].
[tex]a = 2[/tex].
Therefore, the equation of this parabola in vertex form would be[tex]y = 2\, (x - 9) + (-1)[/tex], which is equivalently [tex]y = 2\, (x - 9)^{2} - 1[/tex].

In the school store, pencils cost 15 cents each and erasers cost 10 cents each. There is no tax. Gabby wants to spend exactly $2.00 on pencils and erasers.
How many of each can she buy? Provide detail explanation of your solution process and all possible strategies.
she bought 10 pencils and 5 erasers
Let x represent the number of pencils and y represent the number of erasers.
Gabby wants to spend exactly $2.00 on pencils and erasers, hence:
0.15x - 0.1y = 2 (1)
Therefore x = 10 and y = 5
Therefore she bought 10 pencils and 5 erasers.
