Answer:
B) [tex]f(2)=5[/tex]
Step-by-step explanation:
1. Write the function given:
[tex]f(x)=2x+1[/tex]
2. Find f(2) means to evaluate the function when x=2, so you need to replace x with the number 2, that is:
Replacing x with the number 2:
[tex]f(2)=2*(2)+1[/tex]
Multypling numbers:
[tex]f(2)=4+1[/tex]
Adding the numbers:
[tex]f(2)=5[/tex]
Therefore the answer is B) 5
If you pick a card at random from a well shuffled deck, what is the probability that you get a spade or a king
The probability of drawing a spade or a king from a shuffled 52-card deck is calculated by adding the individual probabilities of drawing a spade and drawing a king, then subtracting the probability of drawing a king that is also a spade. The resulting probability is approximately 0.308, or 30.8%.
Explanation:To answer the question of what is the probability of drawing a spade or a king from a well-shuffled 52-card deck, we need to identify the possible successful outcomes and divide them by the total number of outcomes. A standard deck consists of four suits: clubs, diamonds, hearts, and spades. Each suit consists of 13 cards, so there are 13 spades. Four of these are kings because there's one king in each suit.
First calculate the probability of drawing a spade:
P(spaes) = Number of spades / Total cards in deck = 13/52 = 1/4 = 0.25
Next calculate the probability of drawing a king:
P(king) = Number of kings / Total cards in deck = 4/52 = 1/13 ≈ 0.077
However, we have a slight overlap because a king could also be a spade. Hence, we subtract the probability of drawing a card which is both king and spade:
P(king and spade) = Number of king of spades / Total cards in deck = 1/52 ≈ 0.019
Thus, the probability of drawing a spade or a king is given by the equation:
P(spade or king) = P(spade) + P(king) - P(spade and king) = 0.25 + 0.077 - 0.019 = 0.308
So, the probability of drawing a spade or a king from a shuffled 52-card deck is approximately 0.308, or 30.8%.

Write each ratio as a fraction in simplest form. Then explain its meaning. 4 flutes and two drums
The ratio as a fraction in its simplest form for the Number of drums and flutes is 1:2.
What is a Ratio?A ratio expresses the number of times one number contains another. For example, if a dish of the fruit contains eight oranges and six lemons, the orange-to-lemon ratio is eight to six.
A ratio shows us the number of times a number contains another number. Given the following details:
Number of drums = 2
Number of flutes = 4
The ratio for the number of drums to the number of flutes in its simplest form can be written as,
Number of drums / Number of flutes = 2 / 4
Dividing both the numerator and the denominator of the fraction by 2, we will get,
Number of drums / Number of flutes = 1/2
Hence, the ratio as a fraction in its simplest form for the Number of drums and flutes is 1:2.

For each handmade card Jacquie sells, she makes a profit of $0.35. In one week she made a profit of $42. she sells the cards for $0.75 Part 1 : about how many greeting cards do she sell that week? Part 2 : about how much did she earn before paying expenses?
Answer:
A) 120 cards; and
B) $90.
Explanation: Let x be the number of greeting cards sold that week. She earns $0.35 per card and earned $42; this gives us the equation 0.35x = 42 Divide both sides by 0.35: 0.35x/0.35 = 42/0.35 x = 120 She sold 120 cards. She sells each card for $0.75. This means she earned 0.75(120) = $90.
