Step-by-step explanation:
Answer:
5) 10³: So you do 10* 10*10= 1,000
so 10³= 1,000
All you are doing is takeing the number and multiplying itself to the power.
6) (-7)⁴= so you are taking the -7 in parenthesis and making it positive, then you are taking the positive 7 and doing 7⁴. Once you do that you get positive 2401.
8) 3+6* (-5) to the second (i dont have the symbol) so you are going to do PEMDAS: Parenthesis, Expression, Multipulcation, Divison, Addition and Subtraction. so it would be 5+6*25to the second. So you do multipulcation first, so do 6*25=150. Then do addition and do 150+3=153
Step-by-step explanation:
5) 10³= 1,000
6)(-7)⁴= 7⁴= 2401
8)3+6* (-5) to the second= 3+6* (5) to the second= 3+6* 25= 6*25= 150+3= 153
Answer to 8 is= 153

Answer:
i got 21/1
Step-by-step explanation:
A trade school would like to measure the long-term success of their graduates after they leave the school. The school emais a survey requesting information from graduates about their work experience. One question asks graduates to share their annual salary, and the results of the question will be shared in a brochure for incoming
students. Is it likely that the survey results will provide an accurate estimate of mean annual salary for all of the
school's graduates?
The survey will provide a reasonable estimate of mean annual salary because all graduates were sent the email
survey
The survey will likely overestimate mean annual salary because those with higher salanes may be more likely to respond to the survey
The survey will likely underestimate mean annual salary because there may be more graduates with lower
salanes than higher salaries
The survey will likely overestimate the mean annual salary because the email was only sent to graduates with jobs in their chosen feld
Answer: The survey will likely overestimate mean annual salary because those with higher salanes may be more likely to respond to the survey.
Step-by-step explanation:
We should note that this is voluntary response because despite the fact that the email was sent to the students, a graduate can decide to be part of the sample or not.
In this case, those that have higher salaries will be more likely to respond to their emails than those that have lower salaries. Therefore, the survey will likely overestimate mean annual salary.

Answer:
4
Step-by-step explanation:
x² = 8x - 16

geometry thats finding x y and z of a triangle but my dum self doesn't know this so plz help
Answer:
[tex]x = \frac{48}{\sqrt{3}}[/tex]
[tex]y = \frac{24}{\sqrt{3} }[/tex]
[tex]z = 24[/tex]
Step-by-step explanation:
___________________________________________________________
FACTS TO KNOW BEFORE SOLVING :-
For a triangle with one of it's acute angle α (alpha) , the value of :-
[tex]\sin \alpha = \frac{Side \: opposite \: to \: \alpha }{Hypotenuse}[/tex][tex]\cos \alpha = \frac{Side \: adjacent \: to \: \alpha}{Hypotenuse}[/tex]___________________________________________________________
In the question , first of all lets find the value of z. So,
[tex]\cos 45 = \frac{z}{24\sqrt{2}}[/tex]
[tex]=> \frac{1}{\sqrt{2}} = \frac{z}{24\sqrt{2}}[/tex]
[tex]=> z = \frac{24\sqrt{2}}{\sqrt{2}} = 24[/tex]
Length of the altitude perpendicular to side (z + y) = [tex]\sqrt{(24\sqrt{2})^2 - 24^2} = 24[/tex]
Now , lets find the value x. So,
[tex]\sin 60 = \frac{24}{x}[/tex]
[tex]=> \frac{\sqrt{3}}{2} = \frac{24}{x}[/tex]
[tex]=> x = \frac{48}{\sqrt{3}}[/tex]
Also ,
[tex]\cos 60 = \frac{y}{x}[/tex]
[tex]=> \frac{1}{2} =\frac{y}{\frac{48}{\sqrt{3}}}[/tex]
[tex]=> y = \frac{48}{2\sqrt{3}} = \frac{24}{\sqrt{3}}[/tex]

Joan is trying to get through all 275 episodes of Cheers on DVD. She's already watched 83, and she figures she can get through 4 episodes per day if she really focuses. How many days will it take her to finish the series?
A) 48 days
B) 192 days
C) 50 days
D) 68.75 days
Answer: (a)-48 days
Step-by-step explanation:
Given
Joan is watching 275 episodes of Cheers and already watched 83
She can watch 4 episodes per day
Remaining episode 275-83=192
No of days required to finish Cheers
[tex]\Rightarrow n=\dfrac{192}{4}=48\ \text{days}[/tex]

in 1980, wind turbines in Europe generated about 5 gigawatt-hours of energy. Over the next 15 years, the amount of energy increase by about 59% per year.
NOT A MULTIPLE CHOICE
1a. Write a model giving the amount E of energy t years after 1980.
1b. Use your model determine how much wind energy was generated in 1984.
1c. Determine the year when 80 gigawatt-hours of energy were generated.
9514 1404 393
Answer:
1a. E = 5×1.59^t
1b. 32 GWh
1c. 1986
Step-by-step explanation:
1a. An exponential model looks like
f(t) = a·b^t
where 'a' is the value when t=0, and 'b' is the growth factor in the time period associated with t.
Here, 'a' is 5 (GWh), and 'b' is 1+59% = 1.59. Then the desired model is ...
E = 5·1.59^t . . . . . where t is years after 1980, and E is in GWh.
__
1b. For t=4, we have ...
E = 5·1.59^4 ≈ 31.96 ≈ 32
About 32 GWh was generated in 1984.
__
1c. The value of t for a given value of E is ...
E/5 = 1.59^t . . . . divide by 5
log(E/5) = t·log(1.59) . . . . take logarithms
t = log(E/5)/log(1.59) . . . . divide by the coefficient of t
For E = 80, the years after 1980 are ...
t = log(80/5)/log(1.59) ≈ 5.98
About 80 GWh were generated in 1986.

In the polyhedron above x=5 m and y==20 m. The volume of the polyhedron is _____ m3. Round your answer to the tenths place.
Answer:
523.6 m³
Step-by-step explanation:
The polyhedron is an oblique cone
Volume of oblique cone = ⅓πr²h
r = x = 5 m
h = y = 20 m
Volume = ⅓*π*5²*20
Volume = ⅓*π*25*20
Volume = 523.598777 ≈ 523.6 m³ (nearest tenth)

A roll of a six sided die
Required
Which of the options is true
A) P(Even) = 1/4 and P(Odd) = 3/4
In a die, we have:
[tex]S = \{1,2,3,4,5,6\}[/tex] -- sample space
[tex]E = \{2,4,6\}[/tex] --- Even
[tex]O = \{1,3,5\}[/tex] -- Odd
The probability of even is the number of even sides over total.
i.e.
[tex]P(Even) = 3/6[/tex]
[tex]P(Odd) = 3/6[/tex]
Hence, (a) is incorrect
(b) A) P(Even) = 1/2 and P(Odd) = 3/2
In (a), we have:
[tex]P(Even) = 3/6[/tex]
[tex]P(Odd) = 3/6[/tex]
Simplify each
[tex]P(Even) = 1/2[/tex]
[tex]P(Odd) = 1/2[/tex]
Hence (b) is true
Since (b) is true, (c) and (d) are false

Step-by-step explanation:
3x^3 +7x^2 -x
- ( x^3 -4x +2)
------------------------
The first step is to line up the variables by degree
3x^3 +7x^2 -x
- ( x^3 -4x +2)
----------------------------
Then distribute the minus sign
3x^3 +7x^2 -x
