25 Points I guess.
Answers
Answer:
11 weeks
Step-by-step explanation:
$165 / 15 = 11 weeks
11 weeks
Hope that helps!
The equation of line is given by y = 15x and the number of weeks to save enough money is 11 weeks
What is an Equation of a line?The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the number of weeks be x
Let the cost of trip be y
Let the equation of line be represented as A
Now , the value of A is
Let the first point be P ( 4 , 60 )
Let the second point be Q ( 8 , 120 )
Now , the slope of the line between the two points is
Slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Substituting the values in the equation , we get
Slope m = ( 120 - 60 ) / ( 8 - 4 )
On simplifying the equation , we get
Slope m = 60 / 4
Slope m = 15
Now , the equation of line is y - y₁ = m ( x - x₁ )
Substituting the values in the equation , we get
y - 60 = 15 ( x - 4 )
On simplifying the equation , we get
y - 60 = 15x - 60
Adding 60 on both sides of the equation , we get
y = 15x
Now , the cost of the camping trip is $ 165
Substitute the value of y = 165 , we get
165 = 15x
Divide by 15 on both sides of the equation , we get
x = 165/15
x = 11 weeks
Therefore , the value of x is 11 weeks
Hence , the equation is y = 15x

Patryk has 7 cards.

Patryk takes two of the cards at random.
He works out the product of the numbers on the two cards.
Work out the probability that the product is an odd number.
Answers
Answer:
Probability that the product is an odd number = [tex]\frac{1}{7}[/tex]
Step-by-step explanation:
Given - Patryk has 7 cards. There is a number on each card. 2 3 4 5 6 7 8
Patryk takes two of the cards at random. He works out the product
of the numbers on the two cards.
To find - Work out the probability that the product is an odd number.
Proof -
As we know that Product of two numbers is odd iff both the numbers are odd.
So, we have to find the probabilty that both the card that Patryk choose is odd
Now,
Total number of cards = 7
Total number of odd cards = 3
So, Probability = ³C₂ / ⁷C₂
= [tex]\frac{3!}{2! (3-2)!}. \frac{2! (7 - 2)!}{7!}[/tex]
= [tex]\frac{3!}{2! (1)!}. \frac{2! (5)!}{7!}[/tex]
= [tex]\frac{3!}{(1)!}. \frac{ (5)!}{7.6.5.4.3!}[/tex]
= [tex]\frac{ 5.4.3.2.1}{7.6.5.4}[/tex]
= [tex]\frac{1}{7}[/tex]
∴ we get
Probability that the product is an odd number = [tex]\frac{1}{7}[/tex]

A book cost $10 at one book store.About how much more does the book cost when the book store increase it prices 18%.
Answers
Answer:
11.8
Step-by-step explanation:
18% of 10 so more the decimal only one time because you only have one 0 and you get 1.8. ok then 1.8 to 10 =11.8
The book cost $11.8 when the book store increases its prices by 18%.
What is the percentage?A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.
Given, A book cost $10 at one book store which is 100% of its price.
Now, The book store increases its prices by 18%.
Therefore, The new price of the book is (100 + 18) = 118% of $10 which is,
= (118/100)×10.
= 1.18×10.
= $11.8

If you toss a coin and spin the spinner, what is the probability of landing on heads and spinning blue?
Answers
Answer:
Step-by-step explanation:
There are two sides on a coin, heads and tails. So, the probability of flipping heads is going to be 1/2, as there is one chance out of the two options that you will flip a head. As for spinning blue, there are 3 options that are blue out of the four color options given. So, the probability of spinning blue would be 3/4. Hope this helped :) Take this with a grain of salt, though. It's been a while since I reviewed probabilities.
The required probability of landing on heads and spinning blue is 3/4.
What is probability?Probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.
There are two sides to a coin, heads, and tails.
So, the probability of flipping heads is going to be half, as there is one option out of the two options that you will flip a head.
As for spinning blue, there are three choices that are blue out of the four color options given.
So, the required probability = favorable outcomes / total outcomes
So, the required probability = 3/4
Hence, the probability of spinning blue would be 3/4.
