5. On Monday the price of a company's
stock is $25 per share. On Tuesday the
price drops S2, on Wednesday it rises
S6, on Thursday it rises S3, and on
Friday it drops S4. What was the price at
the end of the week?
Please help meeee
Answer:
$28 per share
Step-by-step explanation:
Monday: $25
Tuesday: "Drops $2" "drops" is a key word for minus. So, 25-2 is 23.
Wednesday: "rises" is a key-word for addition. So, 23 + 6 is 29.
Thursday: "rises" again, is a key-word for addition. So, 29 +3 = 32.
Friday: D= "drops" is a key-word for minus. So your last step is subtracting. 32-1=28.

What is the Next-Now rule and function rule for this table? 50 POINTS! BRAINLIEST TO CORRECT ANSWER.
Any unrelated answer is subject to getting their IP found and get reported.
Answer:
Step-by-step explanation:
I'm not sure what the next now rule but I can give you the function.
y = 5 * 2^x
So the table is constructed by letting 0<=x<=8
For example if x is 3
y = 5 * 2^3
y = 5 * 8 = 40
When x = 3 does y come to 40? According to the chart it does.
Try another one
y = 5 * 2*6
y = 5 * 64
y = 320 Is that what the chart records? Yes it does.
If what the text now rule means is that from the current value of y, you can get the next value, then the formula would be
y_n = 2 * y_(n - 1)
y_7 = 2 * y_6
y_7 = 2 * 320
y_7 = 640
A bottled water company bottles varying sizes of water, from 8-ounce to 1-gallon containers. The company has
determined that the mean quantity in their 20-ounce bottles is 20.8 ounces with a standard deviation of 0.6 ounces. The
bottling plant manager believes his machines are overfilling the bottles. A random sample of 30 bottles is taken, and the
mean number of ounces of water is recorded. Which of the following values of the mean of the sample is most likely to
occur if the true mean number of ounces is 20.8?
19.8
20.4
20.9
21.2
Answer:
No, since a sample mean of 20.9 or more occurred 19 out of 100 times, there is insufficient evidence that the true mean ounces of the bottles of water is greater than 20.8
Step-by-step explanation:

Sandhya secured 630 marks out of 900 and Monica secure 650 marks out of 1300 whose performance is better
Answer:
Sandhya performed better.
Step-by-step explanation:
You can either or simplify the fractions:
[tex]\frac{630}{900}[/tex] and [tex]\frac{650}{1300}[/tex] to simpler forms like [tex]\frac{7}{10}[/tex] and [tex]\frac{1}{2}[/tex] from there you can make the [tex]\frac {1}{2}[/tex] and multiply it by [tex]\frac{5}{5}[/tex] to get [tex]\frac{5}{10}[/tex] and then from there you can see Sandya performed better.
OR
You can divide 630 by 900 and 650 by 1300
630/900 gives you 70
and
650/1300 gives you 50
Clearly, once again Sandhya performed better.

bob is picking randomly from a bag containing tiles member 1 to 10. write down the probability that the number he picks is 7
Answer:
Step-by-step explanation:
a) No of outcomes= 7
total no of outcomes= 10
probability = no of outcomes/total no of outcomes
=7/10
b) 4/10 ( since the outcomes could be 1,2,3,4)
c) no 1 to 10 has 5 odd numbers
so, probability = 5/10 = 1/2
d) multiples of 3 from 1 to 10 are :-
3,6,9= 3 no's
so probability = 3/10

Answer:
2199.11 (with pi)
2198 (with 3.14)
Step-by-step explanation:
A=2πrh+2πr²
A=2π(14)(11)+2π(14)²
A=2π(154)+2π(196)
A=2(483.56)+2(615.44)
A=967.12+1230.88
Juan plans to build a ramp from his window to the sidewalk so he can skateboard right out his window on his way to school. His window is 5ft off the ground and the sidewalk is 12ft from his house.
Given :
Height of the window, h = 5 ft.
Distance of the sidewalk from the house, d = 12 ft.
To Find :
The length of the slope.
Solution :
We know, angle between wall and the floor is 90°.
So, we can say that the system makes an right angle triangle.
Let, length of the ramp is x.
So, Applying Pythagoras theorem in the triangle is :
[tex]x^2 = 5^2 + 12^2 \\\\x^2 = 25 + 144\\\\x^2 = 169\\\\x = 13\ m[/tex]
Therefore, the length of the ramp is 13 m.

Determine whether the system of equations has one solution, no solution, or infinitely many solutions. 4x=10+4y and 2x-2y=15
Answer:
infinitely many solutions
Step-by-step explanation:
Given the simultaneous equation
4x=10+4y... 1
2x-2y=15 .... 2
_____________
4x-4y = 10 * 1
2x-2y = 15 * 2
__________--
4x-4y = 10
4x-4y = 30
Add both equation
8x - 8y = 10+30
8x-8y = 40
Divide though by 8
x-y = 5
x = 5 + y
Since the result gave 1 equation and 2 unknowns, then we will let x =k
k = 5 + y
y = k -5
k can be any integer
(x,y) = (k, k-5)
This show that the equation has infinitely many solutions
A college has a student to teacher ratio of 35 to 2. If there are 170 teachers at the college, how many students attend the
college?
Answer: 2,975

Last year, Amy had $20000 to invest. She invested some of it in an account that paid 8% simple interest per year, and she invested the rest in an account that paid 9% simple interest per year. After one year, she received a total of $1690 in interest. How much did she invest in each account?
Answer:
Amount invested at 8% rate of interest = $11000
Amount invested at 9% rate of interest = $9000
Step-by-step explanation:
Let Amy invested amount in a account with 8% simple interest = $a
Then the interest gained after one year = [tex]\frac{\text{Principal amount}\times \text{Rate of interest}\times \text{Time}}{100}[/tex]
= [tex]\frac{a\times 8\times 1}{100}[/tex]
= 0.08a
Remaining amount for the investment = $(20000 - a)
Interest earned after one year with rate of interest 9%
= [tex]\frac{(20000-a)\times 9\times 1}{100}[/tex]
= $(1800 - 0.09a)
Total interest earned after 1 year = $1690
0.08a + (1800 - 0.09a) = 1690
1800 - 0.01a = 1690
0.01a = 110
a = $11000
Amount invested at 8% rate of interest = $11000
Amount invested at 9% rate of interest = $(20000 - 11000) = $9000

[tex]\therefore 2\dfrac{1}{3} \div \left ( -3\dfrac{2}{3} \right ) = -\dfrac{7}{11}[/tex]
Step-by-step explanation:
The question relates to dividing a fraction by proper and another fraction
The given expression is presented as follows;
[tex]2\dfrac{1}{3} \div \left ( -3\dfrac{2}{3} \right )[/tex]
We rearrange the fractions as improper fractions for easier division as follows;
[tex]2\dfrac{1}{3} = \dfrac{7}{3}[/tex]
[tex]-3\dfrac{2}{3} = -\dfrac{11}{3}[/tex]
Therefore, we have;
[tex]2\dfrac{1}{3} \div \left ( -3\dfrac{2}{3} \right ) = \dfrac{7}{3} \div \left (-\dfrac{11}{3} \right ) = \dfrac{7}{3} \times \left (\dfrac{1}{-\dfrac{11}{3} } \right ) = \dfrac{7}{3} \div \left (-\dfrac{3}{11} \right ) =-\dfrac{7}{11}[/tex]
[tex]\therefore 2\dfrac{1}{3} \div \left ( -3\dfrac{2}{3} \right ) = -\dfrac{7}{11}[/tex]
