Answer:
1- false; 2- true; 3- true; 4-false
Final answer:
The statements about drawing a card higher than 6 and certain to draw an even or odd number are true. It's false that drawing a multiple of 3 is unlikely and that drawing a card less than 8 is unlikely.
Explanation:
The question involves determining the likelihood of drawing a specific card from a shuffled deck of 10 cards numbered 1-10. Let's assess each of the four statements provided.
Card greater than 6: There are 4 cards greater than 6 (7, 8, 9, 10), so the probability is 4 out of 10 or 0.4. This means it is likely, making the statement true.
Multiple of 3: There are 3 multiples of 3 (3, 6, 9), so the probability is 3 out of 10 or 0.3. This is less than half, but not very small, so the statement is subjective; however, we would not generally describe a 30% chance as 'unlikely', hence the statement might be considered false.
Even or odd number: Every card is either even or odd, so it is certain that an even or odd card will be drawn, making the statement true.
Number less than 8: There are 7 cards less than 8 (1 through 7), so the probability is 7 out of 10 or 0.7. This means it's more likely to draw a card less than 8, which means the statement is false.

Answer:
3/5
Step-by-step explanation:
Answer:
slope = [tex]\frac{3}{5}[/tex]
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
y + 4 = [tex]\frac{3}{5}[/tex](x - 7) ← is in point- slope form

Luke sells you cars for $12 each. His expenses are $3.50 per car, plus $34 for tools. How many cars must he sell for his revenue to equal his expenses?
Answer:
Step-by-step explanation:
x = number of cars
12x = 3.50x + 34
12x - 3.50x = 34
8.5x = 34
x = 34/8.5
x = 4 <=====he would have to sell 4 cars
In this case, Luke must sell [tex]\(\boxed{4}\)[/tex] cars for his revenue to equal his expenses.
To determine how many cars Luke must sell for his revenue to equal his expenses, let's define the variables and set up the equation.
Let x be the number of cars Luke sells.
Revenue:
Luke sells each car for $12, so his revenue for selling x cars is:
[tex]\[ \text{Revenue} = 12x \][/tex]
Expenses:
Luke's expenses include $3.50 per car and a fixed cost of $34 for tools. So his total expenses for x cars are:
[tex]\[ \text{Expenses} = 3.50x + 34 \][/tex]
We need to find the number of cars x such that his revenue equals his expenses:
12x = 3.50x + 34
To solve for x subtract 3.50x from both sides:
12x - 3.50x = 34
8.50x = 34
Now, divide both sides by 8.50:
[tex]\[ \text{Expenses} = 3.50x + 34 \][/tex]
x = 4
Therefore, Luke must sell [tex]\(\boxed{4}\)[/tex] cars for his revenue to equal his expenses.

Suppose that y varies inversely with x, and y=2 when x=10.
(A) write an inverse variation equation that relates x and y
(b) find y when x= 4
Answer:
see explanation
Step-by-step explanation:
Given that y varies inversely with x then the equation relating them is
y = [tex]\frac{k}{x}[/tex] ← k is the constant of variation
(A)
To find k use the given condition y = 2 when x = 10
k = yx = 2 × 10 = 20, thus
y = [tex]\frac{20}{x}[/tex] ← equation of variation
(B)
When x = 4, then
y = [tex]\frac{20}{4}[/tex] = 5
Isabel will rent a car for the weekend. She can choose one of two plans. The first plan has an initial fee of $46 and costs an additional $0.13 per mile driven.
The second plan has an initial fee of $55 and costs an additional $0.11 per mile driven.
For what amount of driving do the two plans cost the
To compare the two plans and find the amount of driving for which they cost the same, we can set up an equation and solve for x. The two plans cost the same for 450 miles of driving.
Explanation:To compare the two plans and find the amount of driving for which they cost the same, we need to set up an equation. Let's assume the amount of driving is represented by the variable x. The total cost for Plan 1 can be calculated as:
Total cost = $46 + $0.13x
The total cost for Plan 2 can be calculated as:
Total cost = $55 + $0.11x
We can set the two equations equal to each other and solve for x:
$46 + $0.13x = $55 + $0.11x
$0.02x = $9
x = $9 / $0.02 = 450
Therefore, the two plans cost the same for 450 miles of driving.

Which of the following statements best describes the effect of replacing the graph of y = f(x) with the graph of y = f(x + 6)? The graph of y = f(x) will shift up 6 units. The graph of y = f(x) will shift down 6 units. The graph of y = f(x) will shift left 6 units. The graph of y = f(x) will shift right 6 units.
Answer:
The graph of y = f(x) will shift left 6 units, as shown in figure a.
Step-by-step explanation:
A translation means we are able to move the graph of a function up or down - normally called Vertical Translation - and right or left - commonly called Horizontal Translation.
If we replace the graph of y = f(x) with the graph of y = f(x + 6). It means we have added 6 units to the input, meaning the graph y = f(x) will shift left by 6 units as 6 is being added directly to the x, so it is f(x + 6).
For example, if y = x² is the original function and of 6 is directly added to x i.e. f(x + 6), making it y = (x + 6)². So, we can easily observe that there will be a horizontal translation left of 8 units, as shown in figure a.
So, the graph of y = f(x) will shift left 6 units.

The graph of y = f(x) will shift left 6 units. The correct option is the third one.
Which is the effect of replacing the graph of y = f(x) with the graph of y = f(x + 6)?For any function y = f(x), we define an horizontal translation of N units as:
y = f(x + N)
Where if:
N > 0, the translation is to the left.
N < 0, the translation is to the right.
Here we have:
y = f(x + 6)
So this is a translation of 6 units to the left.

Which equation represents the amount of minutes ( m) that it will take to fill the pool?
The equation which represents the amount of minutes.m that it will take to fill the pool is 200 = 60 + 10m
Which equation represents the amount of minutes ( m) that it will take to fill the pool?
Let
m = amount of minutes that it will take to fill the pool
Gallons of water in the pool = 60 gallons
Capacity of the pool = 200 gallons
Additional gallons added per minutes = 50 gallons / 5
= 10 gallons per minutes
The equation:
200 = 60 + 10m
200 - 60 = 10m
140 = 10m
Divide both sides by 10
m = 140/10
m = 14 minutes
Therefore, it takes Anita 14 minutes to fill the pool.

The price of a train ticket consists of an initial fee plus a constant fee per stop.
The table compares the number of stops and the price of a ticket (in dollars).
Stops Price (dollars)
3 6.50
7 12.50
11 18.50
What is the initial fee?
The initial fee of a train ticket, given a constant fee per stop, can be calculated by finding the constant fee per stop and subtracting the total of this fee for a given number of stops from the total price for those stops. By this calculation, the initial fee is $2.50.
Explanation:To determine the initial fee that is related to the price of a train ticket, which consists of an initial fee plus a constant fee per stop, we should first calculate the cost per stop. We can do this by subtracting the price of a ticket for 3 stops from the price of a ticket for 7 stops. So, we get $12.50 - $6.50 = $6.00. We find the difference in the number of stops, which is 7 - 3 = 4 stops. Divide the total price difference by the difference in the number of stops to get the constant fee per each stop: $6.00 / 4 stops = $1.50 per stop. Now we know the constant fee for each stop, so we subtract that from the total price for 3 stops to find the initial fee: $6.50 - ($1.50 * 3) = $2.50. So, the initial fee is $2.50.
To find the initial fee, we need to determine the additional cost per stop. We can do this by using the formula y = mx + b, where y represents the price of the ticket, x represents the number of stops, m represents the constant fee per stop, and b represents the initial fee.
Using the given data, we can set up two equations using the points (3, 6.50) and (7, 12.50).
By subtracting these two equations, we can determine the value of b, which represents the initial fee. Thus, the initial fee is $3.

[tex]4(p^4) > 2p -3[/tex]
Step-by-step explanation:
Here, the given expressions are:
[tex](4p^4 ), (2p-3)[/tex]
Now, substitute the value of p = 5 in both the given expressions, we get:
[tex]4(p^4) = 4(5^4) = 4 (625) = 2,500\\\implies 4(p^4) = 2,500[/tex]
Similarly,
[tex](2p-3) = 2(5) - 3 = 10 -3 = 7\\\implies 2p - 3 = 7[/tex]
So,now comparing both the values at p = 5, we get:
2,500 > 7
