How do you solve this problem
(2x+8)2=64
Answer:
12
Step-by-step explanation:
If (2x+8)2 = 64, then I would solve it by making sure the numbers in the parentheses equal 32. This is because it would get multiplied by 2 after you find the answer and 32 x 2 is 64. So what times 2 is 24? 12. 12 x 2 is 24, plus 8 is 32, and multiply 32 by 2 and you get 64 :) I'm not the best at explaining btw ;-;

What is the side length of a rectangular prism with a volume of 8 ft3?
Answer:
The side length of the rectangular prism is 2 feet
Step-by-step explanation:
The volume of the rectangle prism = L × W × H, where
L is its lengthW is its widthH is its heightIf the 3 dimensions of the rectangular prism are equal, then its
volume = L × L × L = L³
In the question
∵ The rectangular prism has a volume = 8 ft³
∵ The question asks for its side length
→ That means all dimensions are equal
∴ V = L³
→ Substitute V by 8
∴ 8 = L³
→ Take cube root for both sides
∴ ∛8 = ∛(L³)
∴ 2 = L
∴ L = 2 ft
The side length of the rectangular prism is 2 feet
Find the range of the function
g(x) = 5 + / 4 - x
Answer:
The range of g(x) is [5, ∞) ⇒ (a)
Step-by-step explanation:
The range of the function is the values of y which corresponding to the values of x (domain)
∵ [tex]g(x)=5+\sqrt{4-x}[/tex]
∵ There is no square root for negative values
∴ 4 - x ≥ 0
→ Add x to both sides
∴ 4 - x + x ≥ 0 + x
∴ 4 ≥ x
→ that means x is smaller than or equal to 4
∴ x ≤ 4
→ The greatest value of x = 4
∴ The domain of g(x) = {x : x ≤ 4} ⇒ (-∞, 4]
→ At x = 4
∵ g(4) = 5 + [tex]\sqrt{4-4}[/tex]
∴ g(4) = 5 + 0
∴ g(4) = 5
→ That means the smallest value of y = 5 because [tex]\sqrt{4-x}[/tex] is always
give a positive value which add to 5
∴ The range of g(x) is {y : y ≥ 5} ⇒ [5, ∞)
The right answer is (a)

What is the probability that the true proportion of time spent mowing is exactly equal to the sample proportion
This question is incomplete, the complete question is;
The manager of Lawn and Garden Services would like to estimate the proportion of her employees' time spent performing various gardening and lawn care activities. She has made 400 random observations of a typical worker, with the following results:
Activity Time Observed
Mowing 200
Trimming 80
Raking 40
Miscellaneous 80
What is the probability that the true proportion of time spent mowing is exactly equal to the sample proportio;
Multiple Choice
a) 1
b) 0
c) 5
d) 2
e) 1
Answer:
b) 0
Step-by-step explanation:
Given that;
Activity Time Observed
Mowing 200
Trimming 80
Ranking 40
Miscellaneous 80
Total 400
Now since proportion of time spent on mowing will be
200 / 400 = 0.5
there will be no chance that the true proportion of time spent mowing is exactly equal to the sample proportion.
Where true proportion is 200 and sample is 400
So the probability is 0.

What is this expanded
Im not sure how to expand the negative
Do i do it like -4x-4 and so on or just 4x4. And so on
Answer:
as cheecks
Step-by-step explanation:
Answer:
you should multiply 4 by -5, 5 times, so 4 times -5 = -20 then multiply by -5 = 100 then multiply y -5 = -500 then multiply by -5 = 2,500 then multiply by -5 equals = -12,500
or just 4 times -5 = -20 because I don't know how they teach you.
So if you will expand it it will be eaither-12,500 or -20, it's how they teach you.

Philip went on a 4 day bike trip and rode the following distance. 36.8 miles, 29.67 miles, 38.99 miles and 43.3 miles. what was the average distance he rode every day?
Answer:
37.19
Step-by-step explanation:
36.8+29.67+38.99+43.3= 148.76
148.76 divided by 4(thats how you get the average you add all of them up then divide by the amount of numbers you have)= 37.19

Answer:
Follows are the solution to this question:
Step-by-step explanation:
The missing data is defined in the attached file please find it.
Given:
Admission Status
[tex]\left\begin{array}{ccccc}Ethnography &Acceptable \ Approval &Waitlisted & Turned \ Away & Total\\\\ Hispanic/ Black & 51 &206&143 & 400 \\Asia &57&289&100&446\\White& 62&222&145&429\\ Total & 170& 717& 388& 1275\end{array}\right \\\\\\[/tex]
In point A:
The overall percent of applicants, which is Asia:
[tex]= \frac{446}{1275} \\\\ = 0.3498039 \approx 34.98 \%[/tex]
In point B:
The overall percent of the students, who admitted to Asia:
[tex]P(accepted\ Asian) = P( \frac{Placcepted \ Asian}{Asian})[/tex]
[tex]= \frac{\frac{57}{1275}}{\frac{446}{1275}} \\\\= \frac{57}{1275} \times \frac{1275}{446} \\\\= \frac{57}{446} \\\\= 0.1278027\approx 12.78 \%[/tex]
In point C:
The Asian percentage approved:
[tex]P(Asian/accepted) =\frac{P(accepted, Asian)}{P(accepted)}\\[/tex]
[tex]=\frac{\frac{57}{1275}}{\frac{170}{1275}} \\\\= \frac{57}{1275} \times \frac{1275}{170} \\\\= \frac{57}{170} \\\\= 0.3352941\approx 33.52%[/tex]
In point D:
The number of all students admitted:
[tex]=\frac{170}{1275}\\\\= 0.13333 \\\\= 13.33%[/tex]

f(x) = 2x2 + 20x – 10
Answer:
x = 0.3
Step-by-step explanation:
f(x) = 2x2 + 20x – 10
0 = 4 + 20x - 10
0 = - 6 + 20x
- 20x = - 6
=
x= 3/10 =
x = 0.3
solve 2x+5=12
