In a particular lottery, 5 winning numbers are drawn from a set of 37 numbers. What is the probability of picking exactly 2 of the winning numbers in this lottery? Round your answer to the nearest
thousandth (three decimal places).
Since 5 winning numbers are draw and there are exactly 2 winning numbers, the other 3 numbers chosen have to be incorrect.
The 2 numbers picked right, there are 5C2=10 different possibilities.
The other 3 numbers are just picked from the rest of the 32 numbers. Getting there are 32C3=4960 different possibilities.
For each set of 2 correct winning numbers, you could have the 4960 different losing numbers to match up to make a unique set. This meant that there are 4690*10=46900 different total possibilities.
Now the total different outcomes of how you can choose the numbers are 37C5=435897 outcomes.
Now the way to find probabilities is want/total
The want is 46900 and the total is 435897
Doing the division you get the number rounded to the nearest thousandths as 0.107 or in percent form as
10.759% chance of picking exactly 2 winning numbers.
This seems like a competition problem of some sort therefore I assume that you already know what combinations in form nCk and permutation in form nPk means.

Please help! I filled in a little circle bc i thought it was right XDD
determine an equation and the radius for the circle that has its centre at the origin (0,0) passes through the point A 4-3
Given:
The center of the circle is at (0,0).
The circle passes through the point A(4,-3).
To find:
The radius and the equation of the circle.
Solution:
Distance formula:
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
The radius of the circle is the distance between the points (0,0) and (4,-3).
[tex]r=\sqrt{(4-0)^2+(-3-0)^2}[/tex]
[tex]r=\sqrt{(4)^2+(-3)^2}[/tex]
[tex]r=\sqrt{16+9}[/tex]
[tex]r=\sqrt{25}[/tex]
[tex]r=5[/tex]
So, the radius of the circle is 5 units.
The standard form of a circle is
[tex](x-h)^2+(y-k)^2=r^2[/tex]
Where, (h,k) is center of circle and r is the radius.
Putting h=0, k=0, r=5, we get
[tex](x-0)^2+(y-0)^2=5^2[/tex]
[tex]x^2+y^2=25[/tex]
Therefore, the radius of the circle is 5 units and the equation of the circle is [tex]x^2+y^2=25[/tex].

find the value of x in each triangle with the given angle measures
Answer:
10 - 104
11 - 25
12 - 64
13 - 109
14 - 33
15 - 90
Step-by-step explanation:
For the first 3 triangles u must add the two angles and minus it from 180
Q number 13 do the same thing then minus the number u got by 180
Q number 14 .... 66 - 180 = 33
Q number 15 it is a right angle so it is 90

A study was conducted to investigate whether the mean price of a dozen eggs was different for two different grocery stores, Store A and Store B, in a large city. A carton of one dozen eggs from each store was randomly selected for each of 35 weeks, for a total sample size of 35 cartons from each store. The mean price of the 35 cartons was recorded for each store. The difference in the mean carton price for the stores will be calculated.
Which of the following is the appropriate test for the study?
A one-sample z -test for a population proportion
A one-sample t -test for a sample mean
A matched-pairs t -test for a mean difference
A two-sample t-test for a difference between population means
A two-sample z-test for a difference between population proportions
Answer:
A two-sample t-test for a difference between population means
Step-by-step explanation:
Answer:
D) A two-sample t -test for a difference between population means
Step-by-step explanation:
Two random samples are selected on a quantitative variable, and the difference in the sample means will be calculated. The appropriate test is the two-sample t-test for a difference in population means.

Find the smallest number such that the remainder is 3 when it is divided by 16,20 or 24.
(step required,thank you)
Answer: 123
Step-by-step explanation:
Foe us to solve this, we have to find the lowest common multiple of 16, 20 and 24 first and then add 3 to the LCM. This goes thus:
Multiples of 16 = 16, 32, 48, 64, 80, 96, 112, 128, 144, 160
Multiples of 20 = 20, 40, 60, 80, 10, 120, 140, 160
Multiples of 24 = 24, 48, 72, 96, 120
Therefore, the Lowe's common multiple is 120.
We then add the remainder of 3 and this will give:
= 120 + 3
= 123

Put the following equation of a line into slope-intercept form, simplifying all fractions. x + 2y = 16
Answer:
x + 2y = 16The slope-intercept form is y=mx+b, where m is the slope and b is the y-intercept.
y=mx+b
Rewrite in slope-intercept form.
y= −1/2x+8
Step-by-step explanation:
Hope it is helpful...
Hey there!
The answer is y = [tex]\frac{-1}{2}[/tex]x + 8
To put it into slope-intercept form, we must get "y" by itself on one side of the equation. First, to do this, we will subtract "x" from both sides.
2y = -x + 16
Lastly, we divide both sides by 2
y = [tex]\frac{-1}{2}[/tex]x + 8

Trigonometry help finding the value of x
Answer:
[tex]5\sqrt{3}[/tex] or 8.66
Step-by-step explanation:
use tan:
tan = [tex]\frac{opposite}{adjacent}[/tex]
⇒ tan 60 = [tex]\frac{x}{5}[/tex]
tan of 60 is 1.73
⇒ 1.732 = [tex]\frac{x}{5}[/tex]
multiply 5 on both sides
⇒ 1.732 x 5 = [tex]\frac{x}{5}[/tex] x 5
⇒ 8.66
Answer:
[tex]\boxed {\boxed {\sf D. \ 5 \sqrt 3 \ or \ 8.66}}[/tex]
Step-by-step explanation:
Remember the 3 main trigonometric ratios:
sinθ= opposite/hypotenuse cosθ= adjacent/hypotenuse tanθ= opposite/adjacentWe are given the 60 degree angle. 5 is adjacent to the angle and x is opposite. Therefore, we must tangent.
[tex]tan \theta= \frac {opposite}{adjacent}[/tex]
[tex]tan60=\frac {x}{5}[/tex]
Since we are solving for x, we must isolate that variable. It is being divided by 5 and the inverse of division is multiplication. Multiply both sides by 5.
[tex]5(tan60)=\frac {x}{5} *5[/tex]
[tex]5(tan60)=x\\5*$$1.73205080757= x\\8.66025403784=x[/tex]
If we round to the nearest hundredth, the 0 in the thousandth place tells us to leave the 6.
[tex]8.66 \approx x[/tex]
x is about 8.66 or 5√3, which is choice D.

second choice has 1 column and 2 rows can't multiple this one
third choice has 2 columns and 1 row can't multiple this one
fourth choice has 1 column and 1 row This one can be multiplied

Write an equation that represents the line. (Use exact numbers)
Answer (assuming it can be in slope-intercept form):
[tex]y = \frac{3}{4} x+2[/tex]
Step-by-step explanation:
When knowing the y-intercept and a slope of a line, you can write its equation in slope-intercept form, or y = mx + b format.
1) First, find the slope. Use two points from the graph. We can see that the points (0,2) and (4,5) are on the line, therefore substitute their x and y values into the slope formula [tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex] and solve:
[tex]m = \frac{(5)-(2)}{(4)-(0)} \\m = \frac{5-2}{4-0} \\m = \frac{3}{4}[/tex]
Thus, the slope is [tex]\frac{3}{4}[/tex].
2) Next, find the y-intercept of the line by looking at the graph. The y-intercept is the point at which the line intersects the y-axis. By reading the graph, we can see that that point is (0,2), thus 2 is the y-intercept.
3) Now, using the slope-intercept formula [tex]y = mx + b[/tex], substitute the found values for the [tex]m[/tex] and the [tex]b[/tex] to write the equation of the line.
Since [tex]m[/tex] represents the slope, substitute [tex]\frac{3}{4}[/tex] in its place. Since [tex]b[/tex] represents the y-intercept, substitute 2 in its place. This gives the following answer and equation:
[tex]y = \frac{3}{4} x+2[/tex]
