A study has shown that 23 % of all college textbooks have a price of $ 95 or higher. It is known that the standard deviation of the prices of all college textbooks is $ 8.50 . Suppose the prices of all college textbooks have a normal distribution. What is the mean price of all college textbooks? Round your answer to the nearest integer. μ =
Answer:
μ₀ = 89
Step-by-step explanation:
A study has shown that 23 % of all College textbook cost 95 $ or more, then if the area under the bell shape curve is 23 % in the right tail, then
z(score ) = 0,74 ( 0,23 ≈ 0,2296 from z table )
Then z(score) = ( x - μ₀ ) / σ
0,74 = ( 95 - μ₀ ) / 8,5
0,74*8,5 = 95 - μ₀
6,29 - 95 = - μ₀
μ₀ = 88,71
μ₀ = 89

Let s ( t ) = 6 t 3 − 9 t 2 − 360 t be the equation of motion for a particle. Find a function for the velocity.
Answer:
V(t) = 18t²-18t-360
Step-by-step explanation:
Given the equation of motion of particle expressed as:
s(t) = 6t³-9t²-360t
Velocity is the change in displacement of a body with respect to time.
V(t) = ds(t)/dt
V(t) = 3(6)t²-2(9)t¹-360
V(t) = 18t²-18t-360
Hence the function of the velocity is V(t) = 18t²-18t-360

Does this graph represent a proportional relationship(direct variation). Why?
Answer:
No.
It doesn’t pass through the origin point.
Step-by-step explanation:
Remember that for a graph to represent a proportional relationship, it must meet the following three criteria:
It must pass through the origin point.It must be a line. And it cannot be vertical or horizontal.Our graph is indeed a line.
It is also not vertical or horizontal.
However, it does not pass through the origin point (0, 0).
Therefore, this graph is not a proportional relationship.

O (0,-8). (4,0)
O Answer not given
Can someone help me with this
Answer:
X intercept: 8,0
Y intercept ( 0,-4)
Step-by-step explanation:
Answer:
(-8,0) , (0,4) and our answer is D which is not given in the choices i even attached the graph so you can double check.
Step-by-step explanation:
Arrange the equation into the standard form [tex]y=mx+c[/tex]
so,
[tex]3x-6y=-24\\3x+24=6y\\y=\frac{3x+24}{6} \\\\y=\frac{3x}{6} +\frac{24}{6} \\\\y=\frac{x}{2}+4[/tex]
[tex]y=mx+c[/tex]
if we compare we get c=4 where c is the y-intercept now for the x-intercept which means the coordinate should be (x,0) because x-intercept means the function cuts/intersects the x-axis at (x,0) so we put the coordinate and the value of m(slope) and c(y-intercept) in our equation.
[tex]y=\frac{x}{2}+4\\\\ put (x,0) in the function\\\\0=\frac{x}{2} +4\\\frac{x}{2}=-4 \\x=-8[/tex]
so finally our x-intercept is (-8,0) and y-intercept is (0,4)
1500 teams compete in a tournament. The organizers let the teams know that every game is played with exactly 2 teams and must have a winner and that the team that loses a game is immediately excluded from the tournament. How many games will be played until the champion is known? Show how to use the bijection rule to solve this problem and show a numeric answer.
Answer:
1499
Step-by-step explanation:
Given there are 1500 team in a tournament .
Game is played between exactly 2 team
And looser immediately exclude from tournament.
We calculate the number of game :
We constant divide the number of teams by 2 and the quotient is divided for the next division until we get quotient as 1 and the remainder as 0.
And each time we divide, if the divident is even add quotient to the number of game in tournament if add then quotient + 1 to the number of game in the tournament.

2 +5k = 3k -4 -2help piz
Answer:
k=−4
Step-by-step explanation:
Let's solve your equation step-by-step.
2+5k=3k−4−2
Step 1: Simplify both sides of the equation.
2+5k=3k−4−2
2+5k=3k+−4+−2
5k+2=(3k)+(−4+−2)(Combine Like Terms)
5k+2=3k+−6
5k+2=3k−6
Step 2: Subtract 3k from both sides.
5k+2−3k=3k−6−3k
2k+2=−6
Step 3: Subtract 2 from both sides.
2k+2−2=−6−2
2k=−8
Step 4: Divide both sides by 2.
2k/2=−8/2
k=−4
A cheetah's top speed is about 96 km/h.
A zebra's top speed is about 64 km/h.
If the animals both maintain their top speed for the entire race,
How much of a head start
would a zebra need to tie
a cheetah in a 5 km race?
Answer:
The zebra needs 1.66 Km of a head start to tie the cheetah in the race.
Step-by-step explanation:
The top speed of the cheetah is 96 Km/h.
If the cheetah ran for 5 Km, it would need
5 / 96 hours
The top speed of a zebra is 64 Km/h.
Running the same time, the zebra would travel a distance of:
5 / 96 * 64 = 3.33 Km
It would need an additional distance to tie the cheetah of 5 - 3.33 = 1.66 Km
The zebra needs 1.66 Km of a head start to tie the cheetah in the race.

passes through (6,-3) slope: -1/3 write in slope intercept form
Answer:
y = [tex]-\frac{1}{3}[/tex] x – 1 (see below)
Step-by-step explanation:
First, refer to the slope-intercept formula:
y = mx + b
The variable m represents the slope. The slope is the steepness of the line. The variable b represents the y-intercept. The y-intercept is the point where the line intersects the y-axis.
The slope is already given, so you can plug it in:
y = [tex]-\frac{1}{3}[/tex] x + b
To find the y-intercept, you will need a point on the line. Because there is already a point in which you are required to intersect, you might as well use that point. Also, keep in mind that it's the simplest way to get a line through that point.
First, plug in the point's values (6, –3) into your almost-complete formula:
y = [tex]-\frac{1}{3}[/tex] x + b
–3 = [tex]-\frac{1}{3}[/tex] (6) + b
–3 = –2 + b
–3 + 2 = b
b = –1
Now that you have your y-intercept, your equation is complete:
y = [tex]-\frac{1}{3}[/tex] x – 1

A store had 776 more diet sodas than regular. The ratio of diet sodas to regular sodas was 8:4. How many total sodas were there?
Answer:
1114 sodas
Step-by-step explanation:
If you simplify 8:4, you will get 2:1. Given that information, since there are twice as many diet sodas as regular sodas, all you have to do is divide 776 by 2. You should get 338. All you have to do now is add 776 and 338 to get 1114.

= 121 + 6x - 1 = 180
-121 -121
= 6x - 1 = 59
+1 +1

Check My Work:
65+56+60-1=180
121+60-1=180
120+60=180
180=180
Step-by-step explanation:
65 + 56 + 6x - 1 = 180 original equation
120 + 6x = 180 combine like terms
6x = 60 subtract 120 both sides
x = 10 divide by 6 on both sides
CHECK YOUR WORK:
65 + 56 + 6 (10) - 1 = 180
121 + 60 - 1 = 180
181 - 1 = 180
x = 10
