Bronson is ordering a sundae at a restaurant, and the server tells him that he can have up to four toppings: butterscotch sauce, caramel, peanuts, and strawberries. Since he cannot decide how many of the toppings he wants, he tells the server to surprise him. If the server randomly chooses which toppings to add, what is the probability that Bronson gets just butterscotch sauce, peanuts, and strawberries
Answer:
20%
Step-by-step explanation:
if zero toppings is an option, then there would be 5 possibilities for toppings
0,1,2,3,or 4
the server randomly chose 3 toppings so that would be one out of 5 or 20%.
(If the server did not have the option to put zero toppings on then there would be only 4 options 1,2,3, or 4 toppings and the correct answer would be one out of 4 or 25%.)

Calculate trend values by method of least squares
Answer:
It is a mathematical method and with it gives a fitted trend line for the set of data in such a manner that the following tow conditions are satisfied. The sum of the deviation of the actual values of Y and the computed values of Y is zero.
What are the ordered pairs of the
solutions for this system of equations?
f(x) = x2 – 5x + 3; f(x) = -3
Start by writing the system down, I will use [tex]y[/tex] to represent [tex]f(x)[/tex]
[tex]y=x^2-5x+3\wedge y=-3[/tex]
Substitute the fact that [tex]y=-3[/tex] into the first equation to get,
[tex]-3=x^2-5x+3[/tex]
Simplify into a quadratic form ([tex]ax^2+bx+c=0[/tex]),
[tex]x^2-5x+6=0[/tex]
Now you can use Vieta's rule which states that any quadratic equation can be written in the following form,
[tex]x^2+x(m+n)+mn=0[/tex]
which then must factor into
[tex](x+m)(x+n)=0[/tex]
And the solutions will be [tex]m,n[/tex].
Clearly for small coefficients like ours [tex]5,6[/tex], this is very easy to figure out. To get 5 and 6 we simply say that [tex]m=3, n=2[/tex].
This fits the definition as [tex]5=3+2[/tex] and [tex]6=2\cdot3[/tex].
So as mentioned, solutions will equal to [tex]m=3, n=2[/tex] but these are just x-values in the solution pairs of a form [tex](x,y)[/tex].
To get y-values we must substitute 3 for x in the original equation and then also 2 for x in the original equation. Luckily we already know that substituting either of the two numbers yields a zero.
So the solution pairs are [tex](2,0)[/tex] and [tex](3,0)[/tex].
Hope this helps :)

Patrick walked 3/5 miles on the first day, 5/7 miles on the second day, third day he walked half of the first day’s distance and the last day he walked the first two days' distance. How much distance Patrick has walked altogether?
After the total distance on the first, second and third days, Patrick had walked 3.45miles
Patrick walked altogether 3 miles.
What are fractions?
A fraction is referred to as the portion of a whole in mathematics. For instance, if a pizza is cut into four equal pieces, each one is represented by a quarter. Fractions make calculations quicker and easier by making it easier to distribute and judge numbers.
Solution:
First day patrick walked = 3/5 miles
Second day patrick walked = 5/7 miles
Third day he walked = half of first day
= 1/2 ×3/5
= 3/10 miles
fourth day he walked = first two days distances
= 3/5 ₊ 5/7
= 46/35 miles
Total distance he walked = 3/5 ₊ 5/7 ₊ 3/10 ₊ 46/35
= 3 miles
Hence total distance he walked is 3 miles.

Answer:
[tex]1,814,400[/tex]
Step-by-step explanation:
The number of ways to arrange a word with [tex]d[/tex] distinct digits is each to [tex]d![/tex]. Since there are 10 letters, there are [tex]10![/tex] permutations initially formed.
However, there is one letter that is repeated, S. We need to account for that fact that switching the placement of the S's does not change the word, as they still appear the same. Therefore, divide [tex]10![/tex] by the number of ways you can arrange the 2 S's, which is simply [tex]2![/tex]. Therefore, our answer is:
[tex]\frac{10!}{2!}=10 \cdot 9\cdot 8\cdot 7\cdot 6\cdot 5\cdot 4\cdot 3=\boxed{1,814,000}[/tex]

i don’t understand… but thank you if u do answer my question :))
Answer:
7/0
Step-by-step explanation:
This is because if a number is divided by 0 then there is no answer or it is undefined
Think of it like this,
You have 7 apples and wanted to give it to zero friends, is it possible?
Hope this helped :)
Answer:
Second option (7÷0)
Explanation:
Dividing by zero is considered undefined since you can't divide something by nothing. It's like saying you have a pizza and you want to divide it between 7 people but since you're dividing by zero, you're not splitting the pizza between anyone.

The population of a city has increased by 33% since it was last measured. If the current population is 39,900, what was the previous population?
=___
Answer:
26,733
Step-by-step explanation:
39,900 - Percentage decrease =
39,900 - (33% × 39,900) =
39,900 - 33% × 39,900 =
(1 - 33%) × 39,900 =
(100% - 33%) × 39,900 =
67% × 39,900 =
67 ÷ 100 × 39,900 =
67 × 39,900 ÷ 100 =
2,673,300 ÷ 100 =
26,733

Let Z be the standard normal random variable. Use a probability calculator to answer the following questions: What is the probability Z will be within one standard deviation of average?
Answer:
0.6826 = 68.26% probability Z will be within one standard deviation of average.
Step-by-step explanation:
Normal Probability Distribution
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
What is the probability Z will be within one standard deviation of average?
This is the p-value of Z = 1 subtracted by the p-value of Z = -1.
Z = 1 has a p-value of 0.8413.
Z = -1 has a p-value of 0.1587.
0.8413 - 0.1587 = 0.6826
0.6826 = 68.26% probability Z will be within one standard deviation of average.

Answer:
x ∈ {-35, 0, 35}
Step-by-step explanation:
We can solve for x and equate those values to find corresponding y-values. Substituting into the original expressions for x gives the possible x-values.
[tex]x+xy^2=250y\ \Rightarrow\ x=\dfrac{250y}{1+y^2}\\\\x-xy^2=-240y\ \Rightarrow\ x=\dfrac{-240y}{1-y^2}\\\\\dfrac{250y}{1+y^2}+\dfrac{240y}{1-y^2}=0\\\\\dfrac{25y(1-y^2)+24y(1+y^2)}{(1+y^2)(1-y^2)}=0\\\\y(-y^2+49)=0=y(7-y)(7+y)\ \Rightarrow\ y\in\{-7,0,7\}\\\\x=\dfrac{250(\pm 7)}{1+(\pm7)^2}=\pm35,\quad=\dfrac{250(0)}{1+0^2}=0\\\\\boxed{x\in\{-35,0,35\}}[/tex]
If two angles are complementary, find the measure of each of angle.
Answer:
here's the answer to your question
Answer:
One angle is 70 degrees and the other one is 20 degrees
Step-by-step explanation:
If two angles are complementary, that means that they both add up to 90 degrees.
You have to use algebra to solve this bc you don't have the actual numbers.
So you can use the equation...
7f + 2f = 90
Solve for f, and then substitute the f back into the equation to find the measure of each angle.
7f + 2f = 90
9f = 90
f = 10
Substituting the 10 back in
7f = 7(10) = 70
2f = 2(10) = 20
Solve the right triangle given that mZA= 30°, mZC = 90°, anda = 15. Round your result to one decimal place.
Answer:
[tex]\angle B = 60^o[/tex]
[tex]b =17.3[/tex]
[tex]c = 20[/tex]
Step-by-step explanation:
Given
[tex]a= 15[/tex]
[tex]\angle A = 30^o[/tex]
[tex]\angle C = 90^o[/tex]
See attachment for illustration
Required
Solve the triangle
First, we calculate the measure of B
[tex]\angle A + \angle B + \angle C = 180^o[/tex] --- angles in a triangle
[tex]30^o + \angle B + 90^o = 180^o[/tex]
Collect like terms
[tex]\angle B = 180^o-90^o-30^o[/tex]
[tex]\angle B = 60^o[/tex]
Solve for (c) using sine function
[tex]\sin(30) = \frac{a}{c}[/tex]
Make c the subject
[tex]c = \frac{a}{\sin(30)}[/tex]
Substitute known values
[tex]c = \frac{10}{0.5}[/tex]
[tex]c = 20[/tex]
Solve for (b) using Pythagoras
[tex]c^2 = a^2 + b^2[/tex]
This gives:
[tex]20^2 = 10^2 + b^2[/tex]
[tex]400 = 100 + b^2[/tex]
Collect like terms
[tex]b^2 =400 - 100[/tex]
[tex]b^2 =300[/tex]
Take square roots
[tex]b =17.3[/tex]

point (10,-1) will be in quadrant
Answer:
4
Step-by-step explanation:
The first value (10) is the x value. 10 is positive so the point is on your right. The second value (-1) goes down below the x axis. because it is minus. right and down means you are in the 4th quadrant.
Answer:
IV
Step-by-step explanation:
In the picture below, it shows the model of all quadrants. Since the point (10, -1) has a positive as the x, you can eliminate quadrant II and III. The ones left are I and IV. Since y is a negative, you eliminate I because it is only positives while IV has a negative as it's y.

What is an equation of the line that passes through the points (4,-2) and (8,-7)?
Answer:
the slope-intercept form for any line is y = mx + b, where m is the slope and b is the y-intercept.
now, let's calculate the slope:
=
here is the equation we currently have solved: y = x + b
now we have to solve for the y-intercept. to do this, we substitute one of the given points into the equation, and solve for b.
let's use (8, 2). in this ordered pair, the 8 is the x, and the 2 is the y.
2 = 8 + b
2 - 8 = b
b = -6
and now we have our final equation!
y = x - 6

Step-by-step explanation:
Answer:
y = -5/4x + 3Step-by-step explanation:
Find the slope first:
m = (y2 - y1)/ (2 - x1)m = (-7 + 2)/(8 - 4) = -5/4Use point-slope form and the coordinates of one of the points:
y - y1 = m(x - x1)y - (-2) = -5/4(x - 4)y + 2 = - 5/4x + 5y = -5/4x + 3
