Trucks in a delivery fleet travel a mean of 120 miles per day with a standard deviation of 24 miles per day. The mileage per day is distributed normally. Find the probability that a truck drives between 108 and 153 miles in a day. Round your answer to four decimal places.
Answer:
0.6069
Step-by-step explanation:
Trucks in a delivery fleet travel a mean of 120 miles per day with a standard deviation of 24 miles per day. The mileage per day is distributed normally. Find the probability that a truck drives between 108 and 153 miles in a day. Round your answer to four decimal places.
We solve using z score formula
z = (x-μ)/σ, where x is the raw score, μ is the population mean, and σ is the population standard deviation.
For x = 108 miles
z = ( 108 - 120)/24
z = -0.5
Probability value from Z-Table:
P(x = 108) = 0.30854
For x = 153 miles
z = (153 - 120) /24
= 1.375
Probability value from Z-Table:
P(x = 153) = 0.91543
The probability that a truck drives between 108 and 153 miles in a day is
P(x = 153) - P( x = 108)
0.91543 - 0.30854
= 0.60689
Approximately = 0.6069

Jane needs to solve this equation for x.
2x - 8= 20
Which would be the BEST first step Jane could make to solve the
equation?
A. Add 8 to both sides of the equation
> C. Divide 2x by 2
B. Subtract 8 from the left side of the equation
D. Divide both sides of the equation by 20
Answer:
a
Step-by-step explanation:
because you can't divide by 2 yet
The first step is Add 8 to both sides of the equation
What is equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given:
2x - 8= 20
Now, first step to solve the equation is
Add 8 on both side
2x- 8 +8 = 20 + 8
2x= 28
and, divide both side by 2
x= 28/2
x= 14
Hence, the first step is Add 8 to both sides of the equation

You have $350 to buy 26 tickets for a baseball game. You need to buy some of each kind of seat. You want to spend most of the money. How many of each type of ticket can you buy? Find two different solutions to the problem. Use an equation to show each solution.
Answer:
it would be 700
Step-by-step explanation:
because if you are adding 350 plus 350 then you would get 700
When a number is divided by another number then it gives a quotient and a remainder. The two different solutions to the given problem is given as 26 tickets of one kind and one ticket of the remaining $12.
What is Euclid's division lemma?Euclid's division lemma can be written in mathematical form as
P = QS + R, where a number P divided by number s gives a quotient Q and a remainder R.
It is applicable to both numbers and algebraic expressions.
Given that,
Total amount for buying tickets is $350
Total number of tickets to be bought is 26.
Since the total money available is $350 for 26 tickets, the expression for price of each ticket can be written as,
P = 26t + r
Here, t is the amount for one type of ticket and r is money remained after buying tickets.
The solution to the given division gives quotient as 13 and remainder as 12.
It implies to buy tickets of each kind, 26 tickets can be bought.
And, in order to utilize the amount completely the remaining $12 can be used to buy another kind of ticket.
Hence, the two different solutions to this problem are 26 tickets of one kind and one ticket of another kind for the remaining $12.

Help with trigonometry homework
By definition of tangent,
tan(A - π/4) = sin(A - π/4) / cos(A - π/4)
Expand the numerator and denominator using the angle sum identities for sin and cos:
tan(A - π/4) = (sin(A) cos(π/4) - cos(A) sin(π/4)) / (cos(A) cos(π/4) + sin(A) sin(π/4))
Divide through everything on the right by cos(A) cos(π/4):
tan(A - π/4) = (sin(A) / cos(A) - sin(π/4) / cos(π/4)) / (1 + (sin(A) sin(π/4)) / (cos(A) cos(π/4)))
Simplify the sin/cos terms to tan:
tan(A - π/4) = (tan(A) - tan(π/4)) / (1 + tan(A) tan(π/4))
tan(π/4) = 1, so we're left with
tan(A - π/4) = (tan(A) - 1) / (1 + tan(A))
Replace tan(A) with -√15:
tan(A - π/4) = (-√15 - 1) / (1 - √15)
Then the last option is the correct one.

unit 8 right triangles and trigonometry homework 1
Answer:
x = 31.8
Step-by-step explanation:
From the picture attached,
By applying Pythagoras theorem in right ΔADC,
AC² = AD² + CD²
(22)² = AD² + (16)²
AD² = 484 - 256
AD = √228
= 2√57
Now we apply Pythagoras theorem in right ΔADB,
AB² = AD² + DB²
x² = 228 + (44 - 16)²
x² = 228 + 784
x² = 1012
x = √1012
= 31.81
≈ 31.8
The side x is an hypotenuse side to one of the right triangles formed by
altitude of the given triangle that has solid lines.
x is approximately 31.812
Reasons:
The figure shows a triangle with an altitude that forms two triangles inside
the main triangle.
By Pythagoras's theorem, we have;
For the right triangle on the left;
22² = h² + 16²
h² = 22² - 16² = 228
h² = 228
h = √228 = 2·√57
h = 2·√57
In the right triangle to the right, we have;
The length of the top base, b = 44 - 16 = 28
The square of the hypotenuse, x² = h² + b²
∴ x² = 228 + 28² = 1012
x = √(1012) = 2·√253
x = 2·√253 ≈ 31.812

i will give lots of points and brainly please help asap What is the equation of the quadratic of the quadratic graph with a focus of (1,3) and a directex of y= 1 show your work please
check the picture below.
now, we know the directrix is at y = 1, and the focus point is at 1,3, well, notice the picture, the distance between those fellows is just 2 units.
the vertex is half-way between those fellows, therefore, the vertex will be at 1,2.
the distance "p", from the vertex to either the directrix or focus, is really just 1 unit. Since the focus point is above the directrix, is a vertical parabola, and it opens upwards, like in the picture, and since it opens up, the "p" value is positive, or +1.

A cheetah runs at an average speed of 50 mph between two jungles that are 150 miles apart. An antelope runs at an average speed of 30 mph, a lion runs at an average speed of 25 mph, and an elephant runs at an average speed of 15 mph.
How long does it take each animal to run to the second jungle?
Answer:
cheetah, 3 hours antelope, 5 lion, 6 elephant, 10
Step-by-step explanation:
The time taken by each animal to reach another jungle are:
Cheetah = 3 hours
Antelope = 5 hours
Lion = 6 hours
Elephant = 10 hours
What is speed?Speed is a scalar quantity that refers to how fast an object is moving.
Given are the speeds of different animals,
Cheetah = 50 mph
Antelope = 30 mph
Lion = 25 mph
Elephant = 15 mph
Speed = distance/time.
Time = distance/speed
Distance = 150 miles
Time taken by each :
Cheetah = 150/50 = 3 hours
Antelope = 150/30 = 5 hours
Lion = 150/25 = 6 hours
Elephant = 150/15 = 10 hours
Hence, The time taken by each animal to reach another jungle are:
Cheetah = 3 hours
Antelope = 5 hours
Lion = 6 hours
Elephant = 10 hours
