1 is the answer
Step-by-step explanation:
Number of possible outcomes = 10
Total number of outcome = 10
Probability = [tex] \frac{Number \: of \: possible \: outcomes}{Total \: number \: of \: outcome}[/tex]
[tex] = > \frac{10}{10}[/tex]
[tex] = > 1[/tex]
Hence, the probability of finding number less than or equal to 10 is [tex]1[/tex]

Answer:
option C.
Step-by-step explanation:
option C is the correct answer.
Direct variation: y = kx .........where k is constant.
10 = k * -5
k = -2
Then check if all are linear and matches.
y = -2 * -4
y = 8 ...matches.
then
y = -2 * -3
y = 6 ........matches
then
y = -2 * -2
y = 4 ........matches
then
y = -2*-1
y = 2 ......matches as well. so direct variation.

Answer:
f = 9.25 (I think but maybe I read f(4) wrong)
Step-by-step explanation:
so f(4) means x = 4.
The new equation is
f(4) = 2x4 ^2 - 4 + 9
you first do 2x4^2. The minus 4. The add 9.
the answer to that is 4f = 37
Then solve
F = 9.25

Solve log (x 1) = –x2 10 by graphing. Which equations should be graphed?.
Equal expressions can be taken as equal to some third quantity (which is not used previously, and is new). The equations for given equation to graph are: and
What is logarithm ?When you raise a number with an exponent, there comes a result.
Lets say you get
[tex]a^b = c[/tex]
Then, you can write 'b' in terms of 'a' and 'c' using logarithm as follows
[tex]b = \log_a(c)[/tex]
Log with base 10 is written as [tex]\log(x)[/tex] mostly.
For the given equation, using the above definition, we get:
[tex]log(x+1) = -x^2 + 10\\\\\\(x+1) = 10^{-x^2 + 10}\\x + 1 = 10^(-x^2} \times 10^10 = y\: \: \rm (say)\\[/tex]
Then we get two equations as:
[tex]y = x + 1\\y = 10^(-x^2} \times 10^10[/tex]
Graphing those equations and then getting their common intersection point will give us the solution, as plotted below in the attached graph.

A farmer owns a total of 19 ducks and horses.
The ducks and horses have 64 legs altogether.
How many horses are there?
Answer:
6 ducks and 13 horses
Step-by-step explanation:
Let H and D be the numbers of Horses and Ducks, respectively.
We are told that:
H + D = 19
Our biology book confirms that:
1 horse = 4 legs, and
1 duck = 2 legs
[In most cases on Earth]
So we can say that:
4H + 2D = 64 legs
Rewrite
H + D = 19 as: H = 19 - D
and then substitute:
4H +2D = 64 legs
4(19-D) +2D = 64 legs
76 - 4D + 2D = 64 legs
-2D = - 12
D = 6 [We have 6 ducks]
Then:
H + D = 19
H + 6 = 19
H = 13 [There are 13 horses]
=============================
Check:
Do 6 ducks and 13 horses have a total of 64 legs?
6*2 + 4*13 = 64?
12 + 52 = 64?

The parent function, f(x) = 5^x, has been vertically compressed by a factor of one-half, shifted to the left three units and down two unlts.
Choose the correct function to represent the transformation.
Answer: Choice C
[tex]\displaystyle g(x) = \left(\frac{1}{2}\right)5^{x+3}-2[/tex]
=====================================================
Explanation:
The 1/2 out front handles the vertical compression by 1/2. For example, if two points are vertically spaced by 10 units, then their new vertical distance is now (1/2)*10 = 5 units.
The x+3 in the exponent means "shift 3 units to the left". Effectively what's going on is that the old input x is now x+3, ie 3 units larger than before. This shifts the xy axis itself 3 units to the right. If we held the curve fixed in place while the xy axis moved like this, then it gives the illusion the curve is moving 3 units to the left.
Then finally the -2 at the very end shifts the curve down 2 units. This is because whatever the y coordinate is, we subtract 2 from it to do this vertical shifting. For example, the point (0,62.5) shifts 2 units down to (0,60.5)

Step-by-step explanation:
Let x represent the amount of matches she has in total then...
x-5=75
Add 5 to both sides
x=80
She has 80 matches in total. Now, assuming each box of matches has the SAME amount of matches then she has...

Delisile spends 30% of her income on rent and 50%of the remaining on food and travelling. she pays R2200,00 per month for education and now has R3120,00 left . her monthly income is
The total monthly income of Delisile including her spendings is R 1,520,000
How to find Delisile monthly incomeGiven:
x = Total monthly incomeAmount spent on rent = 39% of x= 0.30x
Amount remaining = x - 0.30x
= 0.70x
Amount spent on food and traveling = 50% of 0.70x
= 0.50 × 0.70x
= 0.35x
Amount spent on education = R 220,000Amount left = R 312,000Total = rent + food + education + amount left
x = 0.30x + 0.35x + 220,000 + 312,000
x = 0.65x + 532,000
x - 0.65x = 532,000
0.35x = 532,000
x = R 1,520,000

Identify the relation that is a function. city name to state name number of apples purchased to the cost of the apples days of the week to the months of the year last name to phone number
Answer:
number of apples purchased to the cost of apples
Step-by-step explanation
The only relation that is a function is number of apples purchased to the cost of the apples.
A relation is considered a function if each input (domain element) is associated with exactly one output (range element). Let's analyze the given relations:
City name to state name: This is not necessarily a function. Multiple cities can be in the same state.
Number of apples purchased to the cost of the apples: This is a function. Each number of apples purchased is associated with a single cost of apples.
Days of the week to the months of the year: This is not a function. Some days of the week might correspond to multiple months.
Last name to phone number: This is not necessarily a function. Different people with the same last name could have different phone numbers.
