Answer:
The profit would be 7.7 million in 2007
Step-by-step explanation:
A veteran math teacher at a large high school claims that 93% of their students pass the state’s final exam. A random sample of 120 of the teacher’s students was chosen, and 108 passed the state’s final exam. Let p hat = the proportion of the random sample who passed the state’s final exam.
The probability that 90% or fewer of this teacher’s students passed the state’s final exam is 0.096. Does this result provide convincing evidence against the teacher’s claim?
Yes, it is expected that at least 90 of the students will pass the state’s final exam.
Yes, the probability of seeing the sample result is so far from what is expected that the probability of it occurring by chance alone is very unlikely.
No, there is a very small chance of seeing the sample result. It is unlikely to occur by chance alone.
No, the difference between the sample result and what is expected is not extreme enough. The probability of it occurring by chance alone is not unlikely.
Answer:
Yes, the probability of seeing the sample result is so far from what is expected that the probability of it occurring by chance alone is very unlikely.

Answer:
C x>3
Step-by-step explanation:
Answer:
The answer is (C) x>3
Step-by-step explanation:
Well first just solve it normally like an equation, ignore the sign for now.
-5x+20<5
Isolate the x so we subtract 20 on both sides
-5x<-15
Now divide by -5 to isolate 5 from X
x>3
You switch the sign because whenever you divide or multiply a negative number to isolate x, the sign reverses.
The circumference of a circular mirror is 31.4 cm. What is the area of the circular mirror in square centimeters? Use pi = 3.14 .
Answer : AREA OF A CIRCLE = PIR2 ( PI ×R ×R )
N.B = R MEANS RADIUS.
GIVEN THE CIRCUMFERENCE, WE WILL USE THE CIRCUMFERENCE TO FIND THE RADIUS.
FORMULA FOR FINDING RADIUS = CIRCUMFERENCE ÷ 2 × 3.142.
SO THAT IS : 31.4 ÷ 6.284 = 4.9. ROUND UP : 5. SO THE RADIUS IS 5. NOW WE CAN FINDING THE AREA. 3.14×5×5 = 78.5 . Say thanks Nique.HELP I NEED HELP ASAP

Answer:
You can narrow it down to A or D because it is clear that football gets more attendance. There is typically a large distance between the 2, for example the first 1 has a distance of 80 and second a distance of 44. This means the answer is likely D, that football averages 50 more people in attendance
Step-by-step explanation:
2 more than the product of 3 and a number is -10.
Answer:
-4
Step-by-step explanation:
2 more than the product of 3 and a number is -10 can be written as 3x+2=-10.
we can take this equation and solve it, first subtracting 2 from both sides to get 3x=-12.
now we divide both sides by 3 to get x=-4, so the answer is -4.

Beth pays for her phone each month based on the number of hours that she uses. Each month she pays $12 for her phone and $2.50 per hour she is using it. What is the total charge for a month in which Beth used the Internet for 90 hours?
Answer:
$237
Step-by-step explanation:
(# of hrs x $ per hr = total $ for all hrs)
90(hrs) x 2.5($ per hr) = 225(total $ fro all hrs)
(total $ for all hrs + initial payment per month = anwer)
225(total $ fro all hrs) + 12(initial payment per month) = 237(answer)

Ellie wanted to build a fence around her rectangular garden. The garden is 10 ft by 20 ft. A) What is the perimeter of the garden in feet?
Answer:
60 feet
Step-by-step explanation:
Perimeter is the sum of the four sides of a rectangle
the formula for the perimeter of a rectangle = 2 x (length + breadth)
2 x (10 + 20)
2 x (30)
= 60 feet
Alternatively, you can add the sides together : 10 + 10 + 20 + 20 = 60 feet

The value of y is directly proportional to the value of x If y=81 when x=54, what is the value of y when x=38
Answer:
y = 57
Step-by-step explanation:
y α x
y = kx ; k = Constant of proportionality
81 = k* 54
k = 81/54
k = 1.5
Value of y when x = 38
y = kx
y = 1.5 * 38
y = 57
Hence, y = 57 when x = 38

Answer:
1. 4x + 6
2. -15x + 11
5. -x + 4
6. -4x + 7
9. 5x - 2
12. x + 16
Step-by-step explanation:
Remove the parenthesis for each one so everything's out in the open. Next, you group like terms. The numbers with variables on one side, and the other numbers on the other side. For example:
x + 3x - 2 + 8
Then, you combine like terms:
4x + 6
That's mostly how you do each one.

which table shows a relationship that is directly proportional?
a b c d?
Answer:
A is the answer because...
Step-by-step explanation:
Let's narrow it down, so it is not D because 8/2=4 but 64/4=16, so already they don't share a slope. It is not B because the numbers don't work together like they should, since we are trying to prove proportionality. It is not C because we are not trying to square the numbers but find a similarity between the numbers, the same slope I mean. So that leaves A which has the slope of 2, test it out now. 0 and 0 are the same, 4/2=2, 8/4=2, 12/6=2. So now you know that A is the correct answer.
Hope you understand! :)

A high school coach wants to buy new athletic shorts for the 15 members of the basketball team. The coach must spend less than $200 on the shorts. Which inequality represents the maximum cost of each pair, s, the coach can buy? 15 s less-than 200 15 s greater-than 200 15 s less-than-or-equal-to 200 15 s greater-than-or-equal-to 200
Answer: 15s must be less than 200
Step-by-step explanation:
Given
A coach must spend $200 for 15 members
s denotes the cost of each short
i.e. cost of 15 shorts must be less than $200
[tex]\Rightarrow 15s<200[/tex]
15s must be less than 200
