The probability of getting a red 7 would be; 1/26
What is the probability?Probability refers to a possibility that deals with the occurrence of random events.
The probability of all the events occurring need to be 1.
Given that the total number of cards is 52.
WE are asked to find the he probability of getting a red 7
Since there are 2 red 7 cards in the deck of cards.
So, the number of favourable outcomes would be 2.
n (E) = 2
The probability
P(E) = n (E) /n (S)
Therefore, the probability of getting a red 7 will be;
P(E) = n (E) /n (S)
P(E) = 2/52
P(E) = 1/26
Hence, The probability of getting a red 7 would be; 1/26

Which of the following ordered pairs represent a direct variation. Find the missing value. 1. (32, 80) and (x, 100) x = _____ 2. (-28,-7) and (20, y) y = _____
When having an ordered pair, we say they are in direct variation if the quotient:
[tex]\frac{y}{x}[/tex]is constant. For case 1 we have:
[tex]\frac{80}{32}=\frac{100}{x}[/tex]we can solve for "x" by multiplying by "x" on both sides:

A mother need 6 pieces of ribbon, with lengths of 25 cm each, for her daughter's hair. If the ribbon is only sold per full meter, how many meters does she need to buy?
Given:
The length of each ribbon is 25 cm.
The number of ribbon need by mother is 6.
Explanation:
Determine the length of ribbon for daughter's hair.
[tex]\begin{gathered} 25\cdot6=150\text{ cm} \\ =1.5\text{ m} \end{gathered}[/tex]Since length is in decimal so we need to find multiple of 25 such that it is more than 150 and multiple of 100.
The multiples of 25 are 25,50, 75, 100, 125, 150, 175, 200, ...
Since 200 is more than 150 and multiple of 100 also.
Determine the length of 200 cm in terms of meters.
[tex]200\text{ cm}\cdot\frac{1\text{ m}}{100\text{ cm}}=2\text{ m}[/tex]So mother needs to buy 2 meters of ribbon.

So, we are writing a function. c(x) is the manufacturing costs, and x is the amount of bikes manufactured. The y-intercept is 1908 because when no bikes are manufactured it still costs 1908 to run the factory. The slope is 75 because it costs $75 to create a bike. So, y = mx + b, where m is the slope and b is the y-intercept is:

Museum entrance tickets cost $25. Then each special exhibit a person wishes to visit costs an additional $4. Write an expression that represents the cost to enter the museum and visit any number of special exhibits. Then find the cost for a person to enter and visit three exhibits.
ANSWER
T = 4x + 25;
T = $37
EXPLANATION
Let the number of special exhibits to be visited be x.
The cost of the musuem entrance ticket is $25 and each special exhibit costs an additional $4.
This means that the cost of cisiting x additional exhibits is:
4 * x = $4x
Therefore, the total cost to enter the musuem and visit any number of special exhibits is:
T = 4x + 25
That is the expression that represents the total cost.
If a person wants to visit three exhibits, it means that:
x = 3
Therefore, the total cost, T, is:
T = 4(3) + 25
T = 12 + 25
T = $37
That is the total cost to enter and visit three exhibits.

We are given the following function
[tex]f(t)=\frac{2t}{3}[/tex]We are asked to find out the value of t which results in f(t) = 64
Let us substitute f(t) = 64 into the above function and solve for t
[tex]\begin{gathered} f(t)=\frac{2t}{3} \\ 64=\frac{2t}{3} \\ 3\cdot64=2t \\ 192=2t \\ \frac{192}{2}=t \\ 96=t \\ t=96 \end{gathered}[/tex]Therefore, the value of t is 96
Write the equation for f(x) and g(x). Then identify the reflection that transforms the graph of f(x) to the graph of g(x).
Given the figure of the functions f(x) and g(x)
The graph of the function is the shown lines
The equation of f(x):
As shown the line of f(x) passes through the points: (-2, 0) and (0, -1)
The slope of the line will be:
[tex]slope=\frac{rise}{run}=\frac{y_2-y_1}{x_2-x_1}=\frac{-1-0}{0-(-2)}=\frac{-1}{2}[/tex]The y-intercept = -1
so, the equation of f(x) =
[tex]f(x)=-\frac{1}{2}x-1[/tex]The equation of g(x):
As shown the line of g(x) passes through the points: (-2, 0) and (0, 1)
The slope of the line will be:
[tex]slope=\frac{rise}{run}=\frac{y_2-y_1}{x_2-x_1}=\frac{1-0}{0-(-2)}=\frac{1}{2}[/tex]The y-intercept = 1
So, the equation of g(x) will be:
[tex]g(x)=\frac{1}{2}x+1[/tex]Identify the reflection that transforms the graph of f(x) to the graph of g(x).
As shown, the functions are symmetric around the x-axis
And as we can see for the same value of x: g(x) = -f(x)
So, the type of transformation is: Reflection over the x-axis

ANSWER
EXPLANATION
Let the length of the rectangle be L.
Let the width of the rectangle be w.
The length of the rectangle is 3 more than twice the width.
This means that:
L = 3 + (2 * w)
L = 2w + 3
The perimeter of a rectangle is given as:
P = 2w + 2L
The perimeter of the rectangle is 96 inches. This means that:
96 = 2L + 2w
Recall that: L = 2w + 3
=> 96 = 2(w) + 2(2w + 3)
=> 2(w) + 2(2w + 3) = 96
Latoya opened a savings account and made an intial deposit. After the intial deposit, she added money into the account each week she added the same amount each week with out any withdrawals after the forth week she had $450 by the ninth week she had $825 what was latoya's intial deposit?
She made an initial deposit that we will call "D", as it is one of the unknowns.
We know that she made a weekly deposit (lets call this amount "w").
After 4 weeks she had $450 in the account balance and this is the sum of the initial deposit and 4 weekly deposits, so we can write:
[tex]D+4w=450[/tex]At the ninth week she had $825, that correspond to the initial deposit and 9 weekly deposits. This can be written as:
[tex]D+9w=825[/tex]We have a system of linear equations that we will solve by elimination: we will substract the first equation from the second and then find w.
[tex]\begin{gathered} (D+9w)-(D+4w)=825-450 \\ 5w=375 \\ w=\frac{375}{5} \\ w=75 \end{gathered}[/tex]Now that we know "w", we can calculate D with any of the two equations:
[tex]\begin{gathered} D+4w=450 \\ D+4\cdot75=450 \\ D+300=450 \\ D=450-300 \\ D=150 \end{gathered}[/tex]Answer: the initial deposit was $150.

Use the graph to answer the following questions.how much does the cost of cheese and crease for each ounce Milan buys? What is the slope of the line?
The graph given is a linear graph,
so that means that the cost of cheese is linearly related to the weight of cheese bought.
The increase in the cost of cheese increase for each ounce Milan buys is, therefore, the slope of the graph;
to find the slope of the graph, we use any two points on the line; i'll be using (4,96) and (2,48)
[tex]\text{slope}=\frac{96-48}{4-2}=\frac{48}{2}=24[/tex]This means that the cost of cheese increases by 24 cents for each ounce Milan buys.
Suppose that the relationship between the tax rate t on imported shoes and the total sales S (in millions of dollars) is given by the function below. Find the tax rate t that maximizes revenue for the government. (Round your answer to three decimal places.)
The given function for the sales of [tex]S(t) = 7 - 6 \cdot \sqrt[3]{t} [/tex], gives the tax rate that maximizes government revenue as t = 343/512
What is a government tax rate?The tax rate is the percentage of an amount that is paid to the government as tax.
The given function is presented as follows;
[tex]S(t) = 7 - 6 \cdot \sqrt[3]{t} [/tex]
Where;
t = The tax rate on imported shoes
S = The total sales

Explanation
[tex]g-0.6\leq3.172[/tex]
Step 1
To solve the inequality means to find a range, or ranges, of values that an unknown g can take and still satisfy the inequality.
so
[tex]\begin{gathered} g-0.6\leq3.172 \\ \text{add 0.6 in both sides} \\ g-0.6+0.6\leq3.172+0.6 \\ g\leq3.772 \end{gathered}[/tex]it means the solution is the set of values equal or smaller than 3.772,so
Part A:
[tex]g\leq3.772[/tex]Step 2
Part B:the graph of the inequality looks like a marked line in the number line, from3.772 to negative infinite, as the symbol is smaller or equal, the number3.772 is part of the set , so we use a filled circle
Step 3
in step 1 we used the addition property of inequality to isolate x, then in step 2 we draw the set solution .
