a: 550-n×55
Step-by-step explanation:
because she withdraws every week 55 then the equation is that
Answer:
a. A = 550 - (n55)b. $165.00Explanation:
a. Amount of remaining dollars = $550 (the initial amount) - (numbers of weeks times $55 that she withdraws weekly)so the equation is: A = 550 - (n55)
b. using the equation in (a) we can determine the amount of money in Shirley's account after 7 weeks.A = 550 - (7×55)
A = 550 - 385
A = $165.00
What value of x will make the equation below true?

sara compares to phone plans. plan A charges $99 for the phone plus $25 per month. plan B charges $39 for a phone and a $35 per month. at what month will the plans cost the same?
Answer: 6th month
Step-by-step explanation:
Let the month where the plans cost the same be represented by x.
Plan A charges $99 for the phone plus $25 per month. This can be written as:
= 99 + 25x
Plan B charges $39 for a phone and a $35 per month. This can be written as:
= 39 + 35x
We then equate both equations and this will be:
99 + 25x = 39 + 35x
Collect like terms
99 - 39 = 35x - 25x
60 = 10x
x = 60/10
x = 6
The plan will cost the same in the 6th month.

Step-by-step explanation:
if the tip amount is around $28.55 and your putting 20% it would $171.29 but it would determine how many people they are.
Alice is a good gambler and always knows when to stop. Suppose in a game, in each round she has a winning probability of 0.8 and she will stop at the first loss. Try to find the upper bound on the probability that she can win at least 10 rounds using Markov's inequality.
Answer:
The answer is "0.500".
Step-by-step explanation:
The chance that round will be won, [tex]P (win) =0.8[/tex]
The likelihood of losing round by complementary law
[tex]P(loss) = 1 -P(win)\\\\[/tex]
[tex]=1-0.8\\\\=0.2\\\\[/tex]
Let X be the number of rounds to the first loss played.
Here, [tex]X \sim Geometric (p=0.2)[/tex]
The PMF of X is the following:
[tex]P(X=x)=p(1-p)^x\\\\[/tex]
[tex]=(0.2)(1-0.2)^x\\\\=(0.2)(0.8)^x, \ \ \ \ \ x=1,2,.....[/tex]
The mean of X is the geometric random variable property, [tex]E(X) =\frac{1}{P}= \frac{1}{0.2}=5\\\\[/tex]
Markov's Inequality:
Suppose X is any random variable that has no negatives. So,
[tex]P(X \geq s)\leq \frac{E(X)}{s} for s >0\\\\[/tex]
Find the upper bound of [tex]P (X \geq 10)[/tex]
[tex]P(X \geq 10) \leq \frac{E(X)}{10}[/tex]
[tex]=\frac{5}{10}\\\\=\frac{1}{2}\\\\=0.5\\\\[/tex]
The highest probability is, therefore, that Markov's inequality will win at least ten rounds: 0.500
Which of the following number cannot represent the 3 sides of a triangle?
{14,28,39}
{4,16,19}
{4,11,13}
{5,16,21}
PLEASE HELP I WILL GIVE BRAINLIEST
Answer:
d 5,16,21 Am sure I think
Step-by-step explanation:
Answer:
{5,16,21}
Step-by-step explanation:
sides of triangle: the sum of every two sides must be greater than the third sides.
{14,28,39}
=> 14 + 28 > 39, 14 + 39 > 28, 28 + 39 > 14 (correct)
{4,16,19}
=> 4 + 16 > 19, 4 + 19 > 16, 16 + 19 > 4 (correct)
{4,11,13}
=> 4 + 11 > 13, 4 + 13 > 11, 11 + 13, > 4 (correct)
{5,16,21}
5 + 16 not > 21 (wrong)

write a real world division problem for which you would drop the remainder
MEANING THERE WOULD BE NO REMAINDER!!!
Answer:
No remainder: Ana has 49 chocolate bars and she wants to give the same amount to each of her seven friends. How many chocolate bars would each friend get?
You have a remainder but don't use it: Ana has a 498 sticker pack. She wants to divide them amongst her 7 friends. How many stickers would each friend get if they all get the same amount?
Step-by-step explanation:
In the first one if you divide 49 by 7 you will get no remainder but in the second one you will
I didn't know what your question meant so I answered it if the problem had no remainder or if the problem did have a remainder but it is not used
Hope this helped :)
Answer:
You are a teacher holding a competition amongst your students. In your class, you have 31 children competing. The prizes that you give them are chocolates. Beforehand, you bought 2 bags of Hershey's Kisses. Inside one bag, there are 70 Hershey's Kisses. In the end of the competition, you teach your students that in your classroom, there are no winners or losers; just learners. You spread the Hershey's Kisses evenly amongst all of your students. You keep the remaining ones left. How many Hershey's Kisses do your students get?

Find the value of x 6x+2
Help Due in 30 mins!
Answer:
Step-by-step explanation:
(6x + 2)° + 42° + 58° = 180°
6x + 2 = 180 - 100
6x = 78
x = 13
Answer:
13
Step-by-step explanation:
There are 180 degrees in a triangle
58 + 42 + (6x +2 ) = 180
98 + (6x + 2) = 180
Subtract 98 from 180.
6x +2 = 82
Subtract 2 from 82
6x = 80
x = 13.333 or 40/3

G varies directly as the square of j and inversely as m. If g=0.05 when j = 0.4 and m=1.6, what is g when j =6 and m=4
Answer: The value of G = 4.5
Step-by-step explanation:
As per given,
[tex]G\propto \dfrac{j^2}{m}[/tex]
When we replace proportional sign with an equal to sign, we get
[tex]G=k\dfrac{j^2}{m}[/tex], where k = constant
If G=0.05 when j = 0.4 and m=1.6, then
[tex]0.05=k\dfrac{0.4^2}{1.6}\\\\ 0.05=k(0.1)\\\\ k=0.5[/tex]
Now,
[tex]G=0.5\dfrac{j^2}{m}\\\\\Rightarrow\ G=0.5\dfrac{6^2}{4}\\\\\Rightarrow\ G=4.5[/tex]
hence, when j =6 and m=4, the value of G = 4.5

help! i just need the answers. maybe some explanations would be good too :)
For Number one: -xy + 2x = 20, x = 5
To solve this, all we need to do is plugin 5 for every place we have x. So...
- (5)y + 2(5) = 20
-5y + 10 = 20
-5y = 10
y = -2
For number two: 4x - 3y - 10 = 1, x = -1
To solve this, we need to plugin -1 for all of the x variables. So...
4 (-1) - 3y - 10 = 1
-4 - 3y - 10 = 1
-14 - 3y = 1
-3y = 15
y = -5
For number three: 5x + 7y = -1, x = 4
We need to plugin -4 for all of the x variables. So...
5 (4) + 7y = -1
20 + 7y = -1
7y = -21
y = -3
For number four: x = 6 + xy, x = -3
Same as the other ones, just plugin -3 for all of the x variables. So...
-3 = 6 + (-3)y
-3 = 6 - 3y
-9 = -3y
3 = y
I hope this helps :)

Answer:
22/75
Step-by-step explanation:
To find the average add up the values and divide the sum by the number of values.
Rewriting all values as fractions, rewriting any negatives if necessary and, setting up as an addition problem
=1/2+1/5+1/5+1/10+7/15
The least common denominator (LCD) is: 30.
Rewriting as equivalent fractions with the LCD:
=15/30+6/30+6/30+3/30+14/30
Rewriting numerators over the common denominator,
=15+6+6+3+1430
Totaling the numerator:
=44/30
Reducing the fraction:
=22/15
Dividing by the number of values: 5
22/15÷5=22/15×15=22/75
Average of the fractions is:
Average=22/75
