ok i have 2 questions first one, is 12.01 larger than 11.999? second question is 0.57 equal to 0.573?
Answer yes, no
Step-by-step explanation:
for number one, 12.01 and 11.999 are being compared
let’s start by looking at the non decimal digits
12 is bigger than 11, so we can assume that anything bigger than 12 is less than anything less than twelve, so the answer is yes
for number two, they are 2 different numbers, so they are not equal
I dont know this no links though

y = |x – 11 – 2
Answer:Correct option is
A
10
Given y=(x−11)
2
⇒y=x
2
−22x+121
After substitute y=25. we get,
x
2
−22x+121−25=0
⇒x
2
−22x+96=0
⇒(x−16)(x−6)=0
⇒x=16,x=6
∴ two points are A,B are (16,25),(6,25).
Distance between A and B is
(16−6)

−(25−25)

=10
Hence, option A is correct.

If -13(q+4) is equal to 7q+16 what’s is q
Answer:
q = - 3.4
Step-by-step explanation:
- 13(q + 4) = 7q + 16 ← distribute parenthesis on left side
- 13q - 52 = 7q + 16 ( subtract 7q from both sides )
- 20q - 52 = 16 ( add 52 to both sides )
- 20q = 68 ( divide both sides by - 20 )
q = - 3.4

2 1/5 to make 5
Answer:
Another 2 1/5
Step-by-step explanation:
2.5 + 2.5 = 5.0 (You don't have to put the .0)
Another example would be:
5.5 + 5.5 = 11.0 (Again, you do not have to put the .0)

Use the probability distribution to complete parts (a) and (b) below.
The number of school-related extracurricular activities per student
Activities 0 1 2 3 4 5 6 7
Probability 0.059 0.121 0.164 0.179 0.212 0.127 0.086 0.052
(a) Find the mean, variance, and standard deviation of the probability distribution.
The mean is 3.3
(Round to one decimal place as needed.)
The variance is
(Round to one decimal place as needed.)
this could take a while to think about but uhh i dont know,
The variance of the probability distribution is 3.4.
To find the variance of the probability distribution, calculate the following:
1. The squared deviation of each activity value from the mean.
2. The product of each squared deviation and its corresponding probability.
3. The sum of these products.
1. Calculate the squared deviation of each activity value from the mean (3.3):
[tex]\[ (0 - 3.3)^2 = 3.3^2 = 10.89 \]\\[/tex]
[tex]\[ (1 - 3.3)^2 = (-2.3)^2 = 5.29 \][/tex]
[tex]\[ (2 - 3.3)^2 = (-1.3)^2 = 1.69 \][/tex]
[tex]\[ (3 - 3.3)^2 = (-0.3)^2 = 0.09 \][/tex]
[tex]\[ (4 - 3.3)^2 = (0.7)^2 = 0.49 \][/tex]
[tex]\[ (5 - 3.3)^2 = (1.7)^2 = 2.89 \][/tex]
[tex]\[ (6 - 3.3)^2 = (2.7)^2 = 7.29 \][/tex]
[tex]\[ (7 - 3.3)^2 = (3.7)^2 = 13.69 \][/tex]
2. the product of each squared deviation and its corresponding probability:
[tex]\[ 0.059 \times 10.89 = 0.64351 \][/tex]
[tex]\[ 0.121 \times 5.29 = 0.63909 \][/tex]
[tex]\[ 0.164 \times 1.69 = 0.27716 \][/tex]
[tex]\[ 0.179 \times 0.09 = 0.01611 \][/tex]
[tex]\[ 0.212 \times 0.49 = 0.10388 \][/tex]
[tex]\[ 0.127 \times 2.89 = 0.36703 \][/tex]
[tex]\[ 0.086 \times 7.29 = 0.62814 \][/tex]
[tex]\[ 0.052 \times 13.69 = 0.71188 \][/tex]
3. Sum up these products to get the variance:
[tex]\[ \text{Variance} = 0.64351 + 0.63909 + 0.27716 + 0.01611 + 0.10388 + 0.36703 + 0.62814 + 0.71188[/tex]
= [tex]3.38680 \][/tex]
=3.4
So, the variance is 3.4.

Check your work
Write A(x) as the product of linear factors.
Answer:
(x - 7)(x - 4)(x + 4).
Step-by-step explanation:
A(x) = x3 – 7x² – 16x +112
Dividing by x-7:
x^2 - 16 <-------- Quotient
-----------------------------
x-7)x^3 - 7x^2 - 16x + 112
x^3 - 7x^2
0 - 16x + 112
- 16x + 112
..............
so A(x) = (x - 7)(x^2 - 16) x^2 - 16 is the difference of 2 squares so we have:
(x - 7)(x - 4)(x + 4).
Checking by expanding the brackets:
(x - 7)(x - 4)(x + 4)
= x(x - 4)(x + 4) - 7(x - 4)(x + 4)
= x(x^2 - 16) - 7(x^2 - 16)
= x^3 - 16x - 7x^2 + 114
= x^3 - 7x^2 - 16x + 112
