Answer:
y=9.75x+60
Step-by-step explanation:
We want our equation to look like y=mx+b
Let's start out by calculating the slope
[tex]\frac{118.5-89.25}{6-3}=9.75[/tex]
we have
y=9.75x+b
we know that when x= 3 y= 89.25
89.25=9.75(3)+b
solve for b = 60

Given triangle QRS with:
∠Q = 100° is opposite to q = 20∠R = ? is opposite to r = 10Use the law of sines to solve:
sin 100 deg / 20 = sin x / 100.98 / 2 = sin ∠R (rounded)sin x∠R = 0.49∠R = arcsin 0.49∠R = 29.3° (rounded)Answer:
29.5
Step-by-step explanation:
original had 29.3 which is not an option. 29.5 is right.
Can someone explain step by step how to do this?
Answer: use the app photomath. its free. you take a picture and it will show you all the steps in depth
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

Given
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

Suppose a large labor union wishes to estimate the mean number of hours per month a union member is absent from work. The union decides to sammple 348 of its members at random and monitor the working time of each of them for 1 month. At the end of the month the total number of hours absent from work is recorded for each employee . if the mean and standard deviation of the sample are x = 7.5 hours and s = 3.5 hours, find a 99% confidence interval for the true mean number of hours a union member is absent per month. Round to the nearest thousandth.
A) 7.5 ± .258
B) 7.5 ± .186
C) 7.5 ± .026
D) 7.5 ± .483

Please Answer!!
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]
In the first week of July, a record 1,100 people went to the local swimming pool. In the second week, 100 fewer people went to the pool than in the first week. In the third week, 130 more people went to the pool than in the second week. In the fourth week, 350 fewer people went to the pool than in the third week. What is the percent decrease in the number of people who went to the pool over these four weeks?

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.
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]
