The sample space for the suits of a standard 52-card deck of cards is {Hearts, Diamonds, Clubs, Spades}.
What is Probability?It is a branch of mathematics that deals with the occurrence of a random event.
The sample space for the suits of a standard 52-card deck of cards consists of four elements, one for each suit:
Hearts
Diamonds
Clubs
Spades
Each card in the deck belongs to one of these four suits. Therefore, the sample space for the suits of a standard 52-card deck of cards is {Hearts, Diamonds, Clubs, Spades}.
Hence, the sample space for the suits of a standard 52-card deck of cards is {Hearts, Diamonds, Clubs, Spades}.

A bank charges 12% simple interest p.a on cash loans to its clients. Titos has asked for a R10 000 loan amount and has promised to repay the loan over 4 years.. 1.4.Calculate the interest which Titos should pay for the loan? 1.1.5. Calculate the total amount tito must pay back after 4 years. 1.1.6. Give one reason why people loan money from banks?
Answer:
1.4. The interest Tito should pay would be R10000 * 12% = R1200 for his first year.
1.1.5. The total amount Tito must pay back after 4 years would be R10000 * (1 + 12%)^4 = R10000 * 1.57351936 = R15735.2 (cor. to 1 d. p.).

Answer:
4800
Explanation:
interest=principle × rate × time/100
interest=10000 ×12 × 4/100
interest= 480000/100
interest=4800
amount=interest+principle
amount=4800+10000
amount=14800
people loan money from banks because they need money at a particular point in time where they do not have it

what is there constant variation of y=kx through (5,8)
The value of constant of variation "k" is
Solution:
Given that the direct variation is:
y = kx ----- eqn 1
Where "k" is the constant of variation
Given that the point is (5, 8)
To find the value of "k" , substitute (x, y) = (5, 8) in eqn 1
Thus the value of constant of variation "k" is k = 8/5 or 1.6

c. 3/2 < x < 5
d. 5 < x < ∞
9514 1404 393
Answer:
a, c
Step-by-step explanation:
There are 3 linear factors, so the function is odd degree (cubic). The coefficients of x are all positive, so the function has the general shape of an increasing function, left-to-right. The three linear factors mean that the curve crosses the x-axis 3 times, changing sign each time.
The x-intercepts are the values of x that make the factors zero: -7, 3/2, 5. The shape of the function tells you it will be negative for x < -7. Between -7 and 3/2, it will be positive, since it changes sign at x=-7. It changes sign again at x=3/2, so will be negative for 3/2 < x < 5.
In short, the function will be negative at any point that has an odd number of function zeros to its right (taking multiplicity into account).
The function is negative on intervals (a) and (c).

Answer:
B.
C.
E.
F.
Step-by-step explanation:
A. no. any log(x) function is increasing. it says to what power I have to put the base to get x. and the bigger x, the bigger also that power number has to be. a log(x) increases much slower than x itself, but it increases.
B. any log(x) can only be calculated for positive x (and not 0).
C. of course. there are no gaps or breaks in a log(x) function. over time, with a growing x, we have to cover every possible y.
D. no. since (0,4) means x=0, this can't be true. as log(0) is power definition undefined (representing minus infinity).
E. yes. see A.
F. yes. for x=1 any log(x) function has to deliver 0 as functional value (to what power do I have to put my base to get 1 ? only base⁰ delivers 1. also 0.725⁰ = 1. therefore, (1,0) is a valid point on the graph.

asking how many combinations are possible is answered by the following expression:

the first step alone offers 14 choices, the second step offers 12 choices. so with these two choices alone there can be 168 different scenarios to choose one from. we just need to keep multiplying for the number of choices we got at each decision to get the number of possible outcomes/configurations

What is the fundamental principle of counting?In the above problem, we use the basic principle of counting to get the result. The principle of multiplication is that if event A can occur in different ways of x and another event B can occur in different ways of y, then there is an x × y way in which both events occur at the same time. is showing. If
events occur in different ways in m, followed by other events in different ways in n, the total number of events in the specified order is m × n. The basic principle of multiplication.

Given that a*b = 2ab - 3b. Determine 2*(3*5)
Answer:
15
Problem:
Given that a*b = 2ab - 3b. Determine 2*(3*5)
Step-by-step explanation:
First we find 3*5 using rule a*b = 2ab - 3b.
3*5=2(3)(5)-3(5)
3*5=30-15
3*5=15
Now we are left with 2*15 in which we will still use the rule a*b=2ab-3b.
2*15=2(2)(15)-3(15)
2*15=60-45
2*15=15
Therefore, 2*(3*5)=15.

Answer:
Step-by-step explanation:
By using linear regression calculator,
Linear regression equation representing the data set will be,
y = 7.79x + 34.27
Correlation coefficient of the line will be,
R = 0.98
Since, correlation coefficient of the line is (+0.98), relation between the two variables is a strong linear relationship.
That means hours spent studying has the strong relation with test scores obtained.
