2/5
If Kostya randomly chooses a number from 1 to 10 then 2/5 is the probability Kostya chooses a number less than 5.
What is Probability?It is a branch of mathematics that deals with the occurrence of a random event.
Given that Kostya randomly chooses a number from 1 to 10.
We have to find the probability he chooses a number less than 5
There are four numbers that are less than 5 .
The numbers less than 5 are 1, 2, 3, 4.
The probability that Kostya randomly chooses one of these numbers is 4/10,
Divide numerator and denominator by 2
We get 2/5
Hence, if Kostya randomly chooses a number from 1 to 10 then 2/5 is the probability he chooses a number less than 5.

Kesley graphed the equation y = 3x + 1 as shown below
First of all, what graph and second, what is "shown below"
The graph will be a line that passes through these points. In this case, the line will have a positive slope of 3 and a y-intercept of 1. None of the options is correct.
The graph of the equation y = 3x + 1 is a straight line.
To graph this equation, we need to plot points that satisfy the equation and then connect those points to create the line.
We can choose any values for x and calculate the corresponding y values using the equation. Let's choose a few x-values to get started:
When x = 0:
y = 3(0) + 1 = 1
So we have the point (0, 1).
When x = 1:
y = 3(1) + 1 = 4
So we have the point (1, 4).
When x = -1:
y = 3(-1) + 1 = -2
So we have the point (-1, -2).
We can continue this process and plot more points to have a clear representation of the line.
Once we have a few points, we can connect them with a straight line.
The resulting graph will be a line that passes through these points. In this case, the line will have a positive slope of 3 and a y-intercept of 1. Since Kesley draws the wrong x-intercept.
None of the given options is correct.

Dominic buys a 64-ounce container of salad mix. About how many ounces of romaine lettuce does the container have? 6 ounces 12 ounces 18 ounces 27 ounces
Hi! here's your answer!ヾ(￣▽￣)
Step-by-step explanation:
Your answer is 18 ounces of romaine lettuce!
Have a nice day/night~ (｡･∀･)ﾉﾞ
The correct option is 18 ounces. The weight of romaine lettuce in salad mix container is 17.28 ounces.
Given to us:
iceberg = 40%
romaine = 27%
spinach = 15%
arugula = 12%
carrots = 6%
The total weight of salad mix container = 64 ounces
Romaine lettuce the container have is 27% of the total weight of salad mix container Dominic buys. Therefore,
weight of romaine lettuce in salad mix container,
= 27% of the total weight of salad mix container
= 27% of 64 ounces
= [tex]\dfrac{27\times 64}{100}[/tex]
=17.28 ounces

The largest z-score available in most tables is 2.99, which corresponds to a probability of 99.86%. A fair coin is
tossed 200 times.
a) What number of heads observedžwould correspond to a z-score of 2.99? [2]
Answer:
The number of heads observed is 121.14 heads
Step-by-step explanation:
The formula for the z-score of a proportion is given as follows;
[tex]z=\dfrac{\hat{p}-p}{\sqrt{\dfrac{pq}{n}}}[/tex]
Where:
[tex]{\hat{p}[/tex] = Sample proportion
p = Population success proportion = 0.5
q = 1 - p = 1 - 0.5 = 0.5
n = Number in of observation = 200
z = 2.99
Hence, we have;
[tex]z=\dfrac{\hat{p}-0.5}{\sqrt{\dfrac{0.5 \times 0.5}{200}}} = 2.99[/tex]
Therefore;
[tex]{\hat{p}-0.5}{} = 2.99 \times \sqrt{\dfrac{0.5 \times 0.5}{200}} = 2.99 \times\dfrac{\sqrt{2} }{40}[/tex]
[tex]{\hat{p}[/tex] = 0.6057
[tex]Whereby \ \hat p = \dfrac{Number \ of \ heads}{Number \ of \ observation} = \dfrac{Number \ of \ heads}{200} = 0.6057[/tex]
∴ The number of heads observed = 200 × 0.6057 = 121.14 heads.
Find the value of x In this triangle
Answer:
x = 25
Step-by-step explanation:
The sum of the angles of a triangle are 180 degrees
2x+ x+15 +90 = 180
Combine like terms
3x+ 105 = 180
Subtract 105 from each side
3x+105-105 = 180-105
3x = 75
Divide each side by 3
3x/3 = 75/3
x = 25
The value of X is 25 degree.

A 2-column table with 4 rows. The first column is labeled x with entries negative 4, negative 1, 3, 5. The second column is labeled f of x with entries negative 2, 5, 4, negative 8.
What is f(5)?
–8
–1

8
Answer:
The value of f(5) is:
-8
Step-by-step explanation:
Lets make table which represents the function.
Th table has 2 columns, first column contains values for x, second column contains values of y
The table has 4 rows, which means that there are 4 values of x, which corresponds to 4 values of y.
The table is given as:
x f(x)
-4 -2
-1 5
3 4
5 -8
We need to find the value of f(5).
We can get the value of f(5) if we substitute x = 5 into f(x)
We can see in the table, that if we substitute x=5 in f(x), we get the value of f(5) = -8

standard form of a pythagorean triplet is 2m, m²+1, m²-1
let us take 2m as 36. so
2m=36, m=36/2
therefore m=18
m²+1 =18²+1 = 324+1 =325
m²-1 =18²-1 = 324-1 =323
therefore 36,325,323 form a pythagorean triplet.
For checking, 36²+323² should be equal to 325²

Step-by-step explanation:
The Pythagorean theorem states that a^2 + b^2 = c^2, where a and b are the legs of the triangle and c is the hypotenuse (diagonal, longest side) of the triangle.
We can see that the legs are labeled 15 (blue) and 8 (red). Substitute that into the equation.
(8)^2 + (15) ^2 = c^2
From there, we can simplify and solve for c.
64 + 225 = c^2. Add.
289 = c^2. Take the square root.
c = 17.

Answer: 17
Pro tip: 3/4/5, 5/12/13 and 8/15/17 are the first three Pythagorean Triples on the list and teachers like to use them for problems. The multiples also come up, like 6/8/10. Learn these and save yourself some calculation down the road.
Let's do it like they want
a² + b² = c²
8² + 15² = c²
64 + 225 = c²
289 = c²
√289 = √c²
17 = c

One light year is equal to 9,460,730,472,580.8 kilometers. Enter this number below in exponential notation. The tolerance on this question is 5%.
________km
Answer:
[tex]9*10^{12}km[/tex]
Step-by-step explanation:
[tex]9,460,730,472,580.8 km[/tex]
First, we can work out 5% of our number, by multiplying it by 0.05
[tex]9,460,730,472,580.8 * 0.05 = 473,036,523,629[/tex]
Now, if we add and subtract our 5% calculated from our original number, we can work out the minimum and maximum value that our final answer can be in the range of.
[tex]9,460,730,472,580.8 + 473,036,523,629 = 9.933767*10^{12}\\9,460,730,472,580.8 - 473,036,523,629 =8.98769395*10^{12}[/tex]
We can see that [tex]9*10^{12}[/tex] is in the range of valid answers, as:
[tex]8.9*10^{12} \leq 9*10^{12} \leq 9.9 * 10^{12}[/tex]
So, our final answer is:

Samantha and Luis are attempting to determine the average number of library books that seventh-grade students check out at one time. Samantha surveys every other seventh grade student leaving the library. She samples a total of 40 of the 200 seventh graders. Luis samples 30 of the 200 seventh grade students at random in the school cafeteria. Whose sample is the most random? Luis because his sample is taken from the population of all seventh graders Luis because he samples fewer students Samantha because she samples more students Samantha because her sample is taken from the population of students who use the library
Answer:
Luis, because his sample is taken from the population of all seventh graders. However, Samanthan has the advantage of having a bigger sample, and that makes it more representative.
Taking the sample of the library as Samantha did, is biased, because most of the students there is checking a book, and the aim of the study is not only the ones that use the library, but in general the seventh grade students.

5. A silo was constructed at a farm in the shape of a right circular cylinder. It was built with an
approximate volume of 842,411 cubic meters and a height of 85 meters. What was the length of the diameter
of the base, to the nearest meter?
Answer: 112 meters
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Volume of a cylinder (V) : π x radius ² x heightReplacing with the values given :
842,411 = π x r ² x 85
Solving for r:
842,411 / (π x 85) = r²
3,154.67 = r²
√3,154.67 = r
56.16 m = r
Finally, we have to multiply the radius by 2 to obtain the diameter:
56.16 x 2 = 112 meters
