Answer:
plug the 5 into the function
f(5)=(5)^2-5
f(5)= 25-5
f(5)=20
Step-by-step explanation:
Answer:
f(5) = 20
Step-by-step explanation:
so, we're going to plug in 5 as our x value, and the equation becomes:
f(5) = [tex](5)^{2}[/tex] - (5)
now we'll simplify
f(5) = 25 - 5
now solve...
f(5) = 20

Milani's teacher draws students names at random, calls on the student, and replaces the name so that students know they should always be prepared to respond. There are 202020 students in Milani's class. Let XXX be the number of names it takes for the teacher to draw Milani's name.
Find the probability that the teacher first draws Milani's name as the 7^{\text{th}}7
th
7, start superscript, start text, t, h, end text, end superscript name.
You may round your answer to the nearest hundredth.
P(X=7)=P(X=7)=
Using the binomial distribution, it is found that there is a 0.0368 = 3.68% probability that the teacher first draws Milani's name as the 7th student.
What is the binomial distribution formula?The formula is:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
The parameters are:
x is the number of successes.n is the number of trials.p is the probability of a success on a single trial.In this problem, there are 20 students, hence in each question the probability that Milani's name is called is p = 1/20 = 0.05.
The probability that the teacher first draws Milani's name as the 7th student is P(X = 0) when n = 6(none during the first six) multiplied by 0.05(called during the seventh), hence:
P(X = 7) = (0.95)^6 x 0.05 = 0.0368.
0.0368 = 3.68% probability that the teacher first draws Milani's name as the 7th student.

Consider the right triangle shown.
What is the length of the other leg?
Round your answer to the nearest tenth
These are the three basic trigonometric ratios:
The sine ratio: [tex]\sin(\theta)=\dfrac{opposite}{hypotenuse}[/tex]The cosine ratio: [tex]\cos(\theta)=\dfrac{adjacent}{hypotenuse}[/tex]The rangent ratio: [tex]\tan(\theta)=\dfrac{opposite}{adjacent}[/tex]Here, 'opposite' or adjacent are referring to the legs in relation to one of the interior angles of the triangle, θ.
We can use these ratios to help us solve for side lengths or angles, depending on what information is given to us and what information we must solve for.
Solving the QuestionWe're given:
The indicated angle (θ) measures 70° The adjacent side measures 5.7 unitsWe must solve for the other leg, which is the 'opposite' sideBecause this question involves the adjacent and the opposite, we can use the tangent ratio to find the answer.
[tex]\tan(\theta)=\dfrac{opposite}{adjacent}[/tex]
⇒ Plug in the given information:
[tex]\tan(70^\circ)=\dfrac{opposite}{5.7}[/tex]
⇒ Multiply both sides by 5.7 to isolate 'opposite:
[tex]5.7\tan(70^\circ)=opposite\\opposite = 15.66062\dots[/tex]
⇒ Round to the nearest tenth:
[tex]opposite=15.7[/tex]
AnswerThe length of the other leg is 15.7 units.
Which equation represents the graph below?
Answer:
y = cos(2x)
Step-by-step explanation:
This is equation must be a cosine function because it starts at a nonzero number. We can conclude that the final answer is D because the amplitude is 1 not 2. Also, the period (2π/k) is equal to 2π/π = 2.
See the image below for the different parts of a cosine/sine function.

6 blue chips 13 pink chips 7 white chips Vicky takes out a chip from the bag randomly without looking. She replaces the chip and then takes out another chip from the bag. What is the probability that Vicky takes out a blue chip in both draws? PLEASE HELLPP
Answer:
9/169Step-by-step explanation:
Total number of chips
6 + 13 + 7 = 26Probability of a blue chip
P(blue) = blue / total = 6 / 26 = 3/13The subsequent blue has same probability as the chip is replaced.
Probability of two blue chips is
P(blue, blue) = 3/13*3/13 = 9/169Answer:
[tex]\sf \dfrac{9}{169}[/tex]
Step-by-step explanation:
The bag has:
6 blue chips13 pink chips7 white chips⇒ Total number of chips = 6 + 13 + 7 = 26
Probability Formula
[tex]\sf Probability\:of\:an\:event\:occurring = \dfrac{Number\:of\:ways\:it\:can\:occur}{Total\:number\:of\:possible\:outcomes}[/tex]
Probability of choosing a blue chip from the first draw:
[tex]\implies \sf P(Blue)=\dfrac{6}{26}[/tex]
As the chips are replaced, the probability of choosing a blue chip from the second draw is the same as the first.
Therefore, the probability of taking out a blue chip in both draws is:

Answer:
2√3
Step-by-step explanation:
root 27

= 3√3
12 upon root 3
= 12 / √3
= ( 12 / √3 ) x ( √3 / √3 )
= ( 12 x √3 ) / ( √3 x √3 )
= 12√3 / 3
= 4√3
6 upon √3
= 6 / √3
= ( 6 / √3 ) x ( √3 / √3 )

at which point do the two equations 3x+5=y+4x and y=x2 intersect? problem is the picture below, the choices are there.
Answer:
A. and D.
Step-by-step explanation:
Hey there!
In order to to find the point at which these two equations intersect at, you need to first rewrite the equations if needed so that they are in the form:
[tex]y=mx+b[/tex]
or
[tex]y=ax^2+bx+c[/tex]
The first equations needs to be rewritten
[tex]3x+5=y+4x[/tex]
make [tex]y[/tex] by itself
[tex]3x+5-4x=y[/tex]
Simplify LHS
[tex]y=-x+5[/tex]
Now we have it in slope-intercept form
Looking at the equation, we can tell that the slope of the line is [tex]-1[/tex] and the y-intercept is 5
Now you can graph this equation easily (image down below)
The second equation is already in form so there is no need to rewrite anything
We can go straight to graphing (image down below)
Now plot both equations on the same graph (image down below)
Stephen borrows $10,000 from his uncle at a simple interest rate of 2%. He repays the loan in full after 3 years. How much money did Stephen pay his uncle back in total?
The total amount of money that Stephen would pay his uncle is equal to $10,600.
How to calculate simple interest.Mathematically, simple interest is calculated by using this formula:
I = PRT
Where:
I is the simple interest.P is the principal.R is the interest rate.T is the time measured in years.Given the following data:
Interest rate = 2% = 0.02.
Principal = $10,000.
Time = 3 years.
Substituting the given parameters into the formula, we have;
I = 10000 × 0.02 × 3
I = $600.
Amount of balance;
A = I + P
A = 600 + 10,000
A = $10,600.

Dan and Paul went shopping at a department store
Dan spent $4 more than Paul spent
Dan spent $24 at the store
Which equation could be used to calculate p, the amount Paul spent?
A. P-4=24
B. 4p=24
C. 4+24=p
D. 4+p=24
Answer:
D 4+p=24
Step-by-step explanation:
So P stands for Paul & how much he spent.
Dan spent $24 at the store & he spent $4 more than Paul, so Paul only spent $20. So P = $20
So which equation would work if you substituted $20 for P?
4 + P = 24
4 + 20 = 24

A water tank is in the shape of a cylinder with a height of 21 feet and a diameter of 8 feet. What is the volume, in cubic feet, of the water tank?
Answer:
1,055.04
Step-By-Step explanation:
Volume equals pi times radius squared times the hight.
You first calculate what the radius will be by dividing the diameter by two and then you procede to multiply the radius to a power of two which is the equvialent as multiplying it to the base number and then you multiply the then squared radius to pi and lastly multiply it by the hight and you have your answer.
[tex]\pi * (8x^{2}) * 21 \\\pi * (4x^{2}) * 21\\\pi * 16 * 21\\50.24 *21\\=1,055.04[/tex]
