Answer:
a(217)=638
Step-by-step explanation:
a(n) = a +(n-1)d
a=-1
d=-7+10=-4+7=3
a(n) = -10 +(n-1)3
a(217) = -10 +(217-1)3
= -10+648
=638

If a certain medicine cures 85% of the people who take it,what is the probability that, if 6 people take the medicine, exactly 4 will be cured?
Answer:
if 6 people take the medicine, around 5 people will get cured if the cure probability is 85%.
Step-by-step explanation:
Given that a certain medicine cures 85% of the people who take it.
As 6 people take the medicine, we need to determine how many will be cured.
As
85% = 85/100 = 0.85
All we need is to multiply 6 with 0.85.
i.e. 6 × 0.85 = 5 (Rounded to the nearest 1 or the Ones Place)
Thus, if 6 people take the medicine, around 5 people will get cured if the cure probability is 85%.
The complex numbers z1 and z2 are graphed. Which point represents z1 – z2?

Step-by-step explanation:
I got it wrong twice and it gave me the answer :)
The point represents z₁ - z₂ will be A. Then the correct option is A.
What is a complex number?The complex number is the combination of the real part and the imaginary part. Then the complex number is given as
⇒ a+bi
The complex numbers z₁ and z₂ are graphed.
The expression of z₁ and z₂ are given below.
z₁ = 4 – i
z₂ = –3 – 2i
Then the difference between z₁ and z₂ will be
z₁ - z₂ = (4 – i) – (–3 – 2i)
z₁ - z₂ = 4 – i + 3 + 2i)
z₁ - z₂ = 7 + i
Then the correct option is A.

1. The base of an open rectangular tank is 3.2 m by 2.8 m. Its height is 2.4 m. It contains
water to a depth of 1.8 m. Cal culate the surface area inside the tank that is not in conta
with water.
Answer:
16.64 m
Step-by-step explanation:
Subtract the depth of the water from the height of the tank (0.6) and use this measurement for height instead. then calculate l•h•2+w•h•2+l•w
(we multiplied the length and height and the width and height by two since there’s two sides with the same measurement for each)
You are eating a slice of pizza that has 391 calories in it. Each time you dip the pizza into ranch dressing, though, you add 7 calories to the total. If your meal wound up being 454 calories in total, how many times did you dip the pizza into ranch dressing? I don't get it
Answer:I think it is about 55 times
Step-by-step explanation:
Answer:
9 times
Step-by-step explanation:
The pizza has 391 calories in it, and everytime you dip it into ranch, you add 7 calories to the 391.
454(calories in total) - 391(calories in the pizza)= 63
63 ÷ 7(calories everytime you dip into ranch) = 9
Buckeye truck rentals has a daily rate of $59.99 plus $0.34/mile. Goodyear truck rentals has the same size truck for 58.95 plus $0.36/mile. At how many mile will the cost be the same?
Answer:
52 miles
Step-by-step explanation:
Step one:
given data
Buckeye truck rentals
daily rate of $59.99
plus $0.34/mile
let the number of miles be x
and the total charge be y
so
y= 0.34x+59.99---------------1
Goodyear truck rentals
daily rate of 58.95
plus $0.36/mile
let the number of miles be x
and the total charge be y
so
y= 0.36x+58.95---------------2
Step two:
Equate the two equations above to find x
0.34x+59.99=0.36x+58.95
collect like terms
59.99-58.95=0.36x-0.34x
1.04=0.02x
divide both sides by 0.02
x= 1.04/0.02
x=52 miles

Answer:
CD = 7
Step-by-step explanation:
Given that the triangles are congruent, then corresponding sides are congruent, that is
CD = AB , substitute values
3y + 1 = 15 - 4y ( add 4y to both sides )
7y + 1 = 15 ( subtract 1 from both sides )
7y = 14 ( divide both sides by 7 )
y = 2
Thus
CD = 3y + 1 = 3(2) + 1 = 6 + 1 = 7

Identify the two factors that were multiplied together to form the array of tiles. Then identify the product of the two factors. Use the variable x in your expressions.
Answer:
[tex]Terms: 3\ and\ x + 2[/tex]
[tex]Product = 3x + 6[/tex]
Step-by-step explanation:
See attachment for complete question.
From the attachment, there are 3 columns and 3 rows
The 3 columns represent the first factor
To get the second factor, we have to analyze the 3 rows in the attachment.
Notice that the first row is bigger than the other two rows.
This big row will be represented with variable x
Notice that the boxes in second row are smaller than the first row and the + sign is written on each of the boxes.
This is represented with + 1
Also, notice that the boxes in third row are smaller than the first row and the + sign is written on each of the boxes.
This is also represented with + 1
Hence, the expression for the rows is x + 1 + 1 = x + 2
The product is then calculated as:
[tex]Product = 3 * (x + 2)[/tex]
[tex]Product = 3 * x + 3*2[/tex]
[tex]Product = 3x + 6[/tex]

Express your answer as a fraction in simplest form.
The solution is
Note: The expression you have written sounds a little unclear, but I am assuming your expression is (27)-2-2/3.
So, I am solving the question based on assuming the expression as (27)-2-2/3, which would still clear your concept.
Answer:
The expression in the simplest form is:
[tex]\left(27\right)-2-\frac{2}{3}=\frac{73}{3}[/tex]
Step-by-step explanation:
Given the expression
[tex]\left(27\right)-2-\frac{2}{3}[/tex]
simplifying the expression in the simplest form
[tex]\left(27\right)-2-\frac{2}{3}[/tex]
[tex]=25-\frac{2}{3}[/tex]
[tex]=\frac{25\cdot \:3-2}{3}[/tex]
[tex]=\frac{73}{3}[/tex]
Thus, the expression in the simplest form is:
[tex]\left(27\right)-2-\frac{2}{3}=\frac{73}{3}[/tex]

your answer.
Answer:
Yes
Step-by-step explanation:
Plug in 4 for x, 5 for y. if it equals, then its a point
5 = -2(4) + 13
5 = -8 + 13
5 = 5
it equals so (4,5) is a point

For each question, solve for the length of the unknown side, as
denoted by the variable. You may round your answers to the nearest
tenth, if necessary. Make sure you show all steps needed to solve the
problem.
Answer:
[tex]a=9[/tex]
Step-by-step explanation:
In this problem, you can use the Pythagorean Theorem ([tex]a^{2} +b^{2} =c^{2}[/tex]) to find what a is. The steps are shown below:
Steps (variables a, b, and c are in italics):
-You can rearrange the formula from the Pythagorean Theorem, which is[tex]a^{2} +b^{2} =c^{2}[/tex] to only get a because we want to know what a is.
Rearranged: [tex]a=\sqrt{c^{2}-b^{2} }[/tex] or [tex]a=-\sqrt{c^{2}-b^{2} }[/tex] It has to ways/options for a because when finding the square root of a number, it can be either positive or negative. But in this problem, it’s going to be positive because we’re finding the length of something.
-Since we know what c and b are, you can plug them into the new formula:
[tex]a=\sqrt{15^{2}-12^{2} }[/tex]
-Simplify it:
[tex]a=\sqrt{225-144}[/tex]
-Subtract inside the radical:
[tex]a=\sqrt{81}[/tex] Then simplify it to get [tex]a=9[/tex].
You can check your answer by putting a back into the original Pythagorean Theorem formula ([tex]a^{2} +b^{2} =c^{2}[/tex]):
Steps
-Plug a, b, and c into the formula [tex]a^{2} +b^{2} =c^{2}[/tex]:
[tex](9)^{2} +(12)^{2} =(15)^{2}[/tex]
-Simplify to get:
[tex]81+144=225[/tex]
-Add:
[tex]225=225[/tex] This is very true. So our answer is correct.
ANSWER: [tex]a=9[/tex]
Sorry for the long explanation, but I hope you understand and that this helps with your question! :)
Answer:
a = 9Step-by-step explanation:
lets make is short and simple
Pythagorean theorem: a² + b² = c²
a² + 12² = 15²
a² = 15² - 12²
a = √81
a = 9
