Answer:
They are all in standard form
Step-by-step explanation:
For any nonnegative real number.
Answer:
A
Step-by-step explanation:
We know that [tex]\sqrt{b}=b^{1/2}[/tex].
We also know that [tex](a^b)^c=a^{bc}[/tex].
We can combine these facts to get [tex](\sqrt{b})^2=(b^{1/2})^2=b^{1/2*2}=b^{1}=b[/tex].
So, the answer is [tex]\boxed{A}[/tex] and we're done!
Note: the non-negative part or the equation comes from the fact that you assume the square root of a negative number doesn't exist. You will change this assumption later in the year, or in further years.

What do you add to
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)

Which statements are true about tthe function represented by the graph?
Select all that apply.
The y-interceptis (0.-2).
The x-interceptis (0,5).
The domain of the function is (-3.3)
The domain of the function is all real numbers.
Answer:
The domain of the function is all real numbers.
Step-by-step explanation:
The answer is not A because the y-axis is the vertical (straight up and down) axis, and it crosses of that at positive 5.
The answer is not B because the x-axis is the horizontal axis, and it crosses that at negative 2.
Don't let them confuse you by saying the intercepts of one is the other!
It is also not C because the answer is D, we know this because the arrows at each end of the arrow signify that the line keeps going infinitely in each direction.
Hope this helps!
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.

The teacher-student ratio at Dunn Middle School is 1 to 23. If there are 966 students, how many
teachers are there?
Answer:
42 teachers
Explanation:
Teacher to student ratio is 1:23
If there are 966 students, then divide by 23 to get how many teachers their are.
966/23=42
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
