Answer:
7a^2b-4ab^2-ab+10a
Step-by-step explanation:
(12a^2b+8a-5a^2b+2ab)-(4ab^2+6ab-2a-3ab)
12a^2b+8a-5a^2b+2ab-4ab^2-6ab+2a+3ab
(12a^2b-5a^2b)+(-4ab^2)+(2ab+3ab-6ab)+(8a+2a)
7a^2b-4ab^2-ab+10a

For problems 11 and 12, find the area of the figure. Round your answer to the nearest tenth, if necessary.
Answer:
Step-by-step explanation:
11)
A= (B x H)/2
A= (2.9x3.2)/2= 4.64cm²
12)
A= (B+b)H /2
A= (12+10)5.6 /2 = 61.6in
Answer:
I think that the answer might be 9.30 for the first one and the second one I think is 670.
Step-by-step explanation:
To find the area, you have to multiply the height and width for the two figures.
3.2 × 2.9 = 9.28
12 × 10 × 5.6 = 672
I think you round those to the nearest tenth. 9.28 would be 9.30 and 672 would be 670. I hope this answers your question.
What is 2/5% as a fraction?
33% of US adults say they are more likely to make a purchase during a sales tax holiday you randomly select 10 adults find the probability that the number of adults who say they are more likely to make purchases during the sales tax holiday is exactly 2
Answer:
0.199
Step-by-step explanation:
p = 33% = 0.33
1 - p = 1 - 0.33 = 0.67
Using binomial distribution formula :
P(x =x) = nCx * p^x * (1 - p)^(n - x)
P(x = 2) = 10C2 * 0.33^2 * 0.67^8
P(x = 2) = 45 * 0.1089 * 0.0406067677556641
P(x = 2) = 0.19899346538663192205
P(x = 2) = 0.1989
P(x = 2) = 0.1990

۔what set builder notation is = (2,3,5,7,11)this p
Given:
The set is:
[tex]\{2,3,5,7,11\}[/tex]
To find:
The set builder notation for the given set.
Solution:
Consider the given set:
[tex]S=\{2,3,5,7,11\}[/tex]
The element of given set are 2, 3, 5, 7, 11 and so on. These area the prime numbers.
If x defines each element of the set then x must belongs to P which is the set of prime numbers. So, the given set can be written as
[tex]S=\{x|x\in P\}[/tex]
Therefore, the set builder notation for the given set is [tex]\{x|x\in P\}[/tex].

On a hospital floor, 16 patients have a disease with a mortality rate of 0.1. Find the probability that two of them die. Round to three decimal places
Answer:
The probability that two of them
die is 0.257
Step-by-step explanation:
From the question, we have that the mortality rate is 0.1
So the probability that they will survive is 1-0.1 = 0.9
Now, we want to check that two will die
We are going you use the Bernoulli approximation of the Binomial theorem as follows
= nCr * p^n * q^(n-r)
where n = 16
r = 2
P = 0.1
q = 0.9
Substituting these values;
14 C 2 * 0.1^2 * 0.9^12
= 0.257

there were 64 basketball games during the NCAA tournament 16 of those games were decided by 3 points or less what percentage of games were decided by 3 points or less
Answer:
25%
Step-by-step explanation:
We can use a proportion to answer this question:
64 represent the 100% of the games
so:
x : 100 = 16 : 64
x = (16*100)/64 = 1600/64 = 25%

12÷8=1.50Sammy won 40 bouncy balls at the fall festival. Later, she gave two to each of her friends. She has 8 remaining. How many friends did she give the balls to.
Answer:
Sammy would have 16 friends.
Step-by-step explanation:
Let total number of friends be x, each friend gets 2 balls, this can be denoted as 2x balls.
The final relation can be expressed as:
40 (total number) =2x+8 , here 8 is the remainder after distribution.
Now we can solve for x
40=2x+8
40−8=2x
32=2x
x=16
Answer:
16 friends
Step-by-step explanation:
40 balls - 8 remaining = 32 balls in total
32 b in total / 2 balls each = 16 friends

What is the equation of a line with a slope of 2, that goes through the point (12,5)?
Answer:
[tex] y = 2x-19 [/tex]
Step-by-step explanation:
Line passes through the point [tex] (12,\: 5) =(x_1,\: y_1) [/tex] and has a slope (m) = 2
Equation of line in point slope form is given as:
[tex] y - y_1 = m(x-x_1) [/tex]
[tex]\therefore y - 5 = 2(x-12) [/tex]
[tex]\therefore y = 2x-24+5 [/tex]
[tex]\therefore y = 2x-19 [/tex]
