The probability of not drawing a 5 from the deck is 48/52.
What is probability?
Simply put, probability measures how probable something is to occur. We can discuss the probabilities of various outcomes, or how likely they are, whenever we are unsure of how an event will turn out. Statistics is the study of events subject to probability.
There are 4 number 5's in the deck of 52 cards.
They are as follows:
The 5 of clubs, the 5 of spades, the 5 of hearts, and the 5 of diamonds.
Using the formula,
Probability = (Number of possible outcomes)/(Total number of outcomes)

How many 1/2 cup servings are in a package of cheese that contains 5 1/4 cups altogether?
There are 10.5 1/2 cup servings in a package of cheese that contains 5 1/4 cups altogether.
How to calculate the number of cups?A ratio is the relationship or comparison between two numbers belonging to the same unit in order to determine how much larger one number is than the other.Because the numerator is a decimal value, the ratio 10.2/34 isn't one. This number can be expressed as a ratio by multiplying the numerator and denominator by the appropriate power of ten to get rid of the decimal point.To find the number of 1/2 cup servings in a package of cheese that contains 5 1/4 cups altogether, we first need to convert the total amount of cheese in cups to a number of 1/2 cup servings.
We can do this by dividing the total amount of cheese by the size of a 1/2 cup serving.
First, we need to convert the amount of cheese in cups to a decimal number. Since there are two 1/2 cups in a cup, the decimal equivalent of 1/2 cup is 0.5. Therefore, the decimal equivalent of 5 1/4 cups is 5.25 cups.
Next, we need to divide the total amount of cheese in cups by the size of a 1/2 cup serving. Since the size of a 1/2 cup serving is 0.5 cups,
we can divide 5.25 cups by 0.5 cups to find the number of 1/2 cup servings as follows:
5.25 cups / 0.5 cups = 10.5
Therefore, there are 10.5 1/2 cup servings in a package of cheese that contains 5 1/4 cups altogether.

2. It is false that the differential equation is non-linear.
The statement regarding the differential equation y''y + (y')² = sin(x) is false.
3. Statement 3: fourth order and nonlinear differential equation.
How to classify the differential equations?For a linear differential equation, the coefficients of y or the derivatives of y are either:
Constant terms.Other variables that are not y.Hence the differential equation for question 2 is linear, as the coefficients of the derivatives are x and -1, neither of which is y, hence the statement is false.
For the differential equation y''y + (y')² = sin(x), we have that:
It is non-linear, as y multiplies y''.It is of the second order, as the order of the highest derivative is of 2.For the differential equation in item 3, we have that:
It is of the fourth order, as the derivative of the third order multiplies the derivative of the first order.It is non linear, as the variable y multiplies the derivative of the third order of y.Hence statement 3 is correct.

What is a joint probability?Joint probability is the probability of two events happening simultaneously.
Let P(A) = probability that event A takes place and P(B) = probability that event B takes place. Then, probability of event A and B happening together i.e. P(A and B) is called joint probability.
What is the Calculation of joint probability?(1) When A and B are independent events: When event A has no impact on event B or vice versa, the two events are said to be independent. For independent events, formula for joint probability is:
P(A and B) = P(A) × P(B)
Example: I am performing two acts at a time (i) tossing a coin and (ii) throwing a dice. What is the probability that the coin shows up “head” and the dice shows up “3”?
There is no doubt that getting “head” on coin and getting “3” on dice are independent events.
Probability of the coin showing up “head” = 1/2
Probability of the dice showing up “3” = 1/6
Therefore, probability of getting “head” on coin and “3” on dice = (1/2)×(1/6) = 1/12
(2) When A and B are dependent events: If event A and event B cannot be considered independent, calculation of joint probability requires knowledge of conditional probability. For dependent events, formula for joint probability is:
P(A and B) = P(A) × P(B, given A) = P(B) × P(A, given B).

Answer:
A.) The sum will be an even integer.
Step-by-step explanation:
The conjecture that can be made about the sum of two even integers and one odd integer is that the sum will be an even integer. This is because even integers are numbers that are divisible by 2, and odd integers are numbers that are not divisible by 2.
For example, consider the sum of the even integer 6 and the odd integer 7. The sum of these two numbers is [tex]6 + 7 = 13[/tex], which is an odd integer. However, if we add another even integer to the sum, such as 4, the resulting sum is [tex]13 + 4 = 17[/tex], which is an even integer. This shows that the sum of two even integers and one odd integer is always an even integer.
This conjecture can be proven using mathematical induction. We can start by showing that the sum of any two even integers and one odd integer is always an even integer. Then, we can assume that the sum of any n even integers and one odd integer is also an even integer. Finally, we can show that the sum of n+1 even integers and one odd integer is also an even integer, using the assumption that the sum of n even integers and one odd integer is even. This will prove that the conjecture is always true.
a candy distributor needs to mix a 10% fat content chocolate with a 30% fat content chocolate to create 100 kg of at 18% fat content chocolate. how many kilograms of each kind of chocolate must they use?
Solving a system of equations we will see that they need to use:
40 kg of the 30% fat content chocolate.60 kg of the 10% fat content chocolate.How many kilograms of each kind of chocolate must they use?Let's define the variables:
x = kilograms of the 10% fat-content chocolate.
y = kilograms of the 30% fat-content chocolate.
We know that they want to create 100kg, then:
x + y =100
And the fat content must be 18%, then we can write the concentration equation:
0.1*x + 0.3*y = 0.18*100 = 18
The coefficients are the percentages in decimal form.
Now we have a little system of equations:
x + y =100
0.1*x + 0.3*y = 18
Isolating x on the first one we get:
x = 100 - y
Replacing that in the other equation we get:
0.1*(100 - y) + 0.3*y = 18
10 + 0.2*y = 18
0.2*y = 18 - 10 = 8
y = 8/0.2 = 40
They need to use 40kg of the 30% chocolate and 60kg of the 10% chocolate.

Time can be described in mathematics as an ongoing and continuous series of events that take place one after another, from the past through the present, and into the future. The duration of events or the gaps between them can be measured, compared, or even ordered using time.
Time is the ongoing progression of existence and things that happen in what seems to be an irrevocable order from the past, present, and forward into the future.
Time is defined by physicists as the flow of events from the past through the present and into the future. In essence, a system is timeless if it is unchanging. When describing events that take place in three-dimensional space, time can be thought of as the fourth dimension of reality.

The equation or tape diagram could be used to represent the context if j represents each bottle of juice costs is; Option D tape diagram
How to Represent Algebraic equations?We are told that;
1 bag of popcorn costs $1.59
She bought a 5-pack of juice bottles
Total cost before tax = $13.34
Now, we are told that j represents each bottle of juice costs. Thus;
Cost of the 5 packs of juice = 5j
Thus, the equation of the total cost before tax is;
1.59 + 5j = 13.34
Looking at the options, only the tape diagram in option D correctly represents the required equation.

Alex learned 80 new vocabulary words for his English exam. The following function gives the number of words he remembers after t days: W(t) = 80(1 - 0.1t)^3 What is the instantaneous rate of change of the number of words Alex remembers after 5 days? Choose 1 answer: A. 10 days B. 10 words per day C. -6 days D. -6 words per day
The instantaneous rate of change is -6 words per day,
the number of words Alex remembers after 5 days, option (D).
What is the instantaneous rate of change ?
An instantaneous rate is the rate at some instant in time. An instantaneous rate is a differential rate: -d[reactant]/dt or d[product]/dt. We determine an instantaneous rate at time t: by calculating the negative of the slope of the curve of concentration of a reactant versus time at time t.
Have given,
Alex learned 80 new vocabulary words
and after t days he learned,
W(t) = [tex]80 (1-0.1t)^{3}[/tex]
differentiate respect of t
W'(t) = [tex]80 \frac{d}{dt} (1-0.1t)^{3}[/tex]
W'(t) = [tex]80 * 3(1-0.1t)^{2} \frac{d}{dt}(1-0.1t)[/tex]
W'(t) = [tex]240(1-0.1*5)^{2} (0.1)[/tex]
W'(t) = 6
That's mean , the instantaneous rate of change is -6 words per day.
