Probability[(X - μ) < 1.1] = 0.6046
Step-by-step explanation:
Given:
σ² = 64
Mean μ = 34
Find:
Probability[(X - μ) < 1.1]
Computation:
Standard deviation σ = √σ²
Standard deviation σ = √64
Standard deviation σ = 8
Probability[(X - μ) < 1.1] = Probability[-1.1 < (X - μ) < 1.1]
Probability[(X - μ) < 1.1] = Probability[-1.1/(8/√38) < (X - μ) < 1.1/(8/√38)]
Using z table
Probability[(X - μ) < 1.1] = 0.6046
Katja's grade was lowered 3 points every time she was late

number represents the change in Katja's grade?
Answers
Answer: -18
Step-by-step explanation:
We know that Kayla’s grade was lowered every time she was late to class. Taking this into consideration, we multiply -3 and 6 (beacuse she was late to class 6 times; 3 is negative because her grade is decreasing) which results in -18.

HURRYYYYYYYYYYYYYYYYY! Justin’s doctor said that the expression StartFraction x + y + 5 over 2 EndFraction, where x and y are his parents’ current heights in inches, gives an estimate of how tall Justin will be as an adult. Justin’s work evaluating the formula is shown below. Mom’s height = 54 inches Dad’s height = 71 inches StartFraction 71 + 54 + 5 over 2 EndFraction = 71 + 27 + 5 = 103 inches What error did Justin make? A. He should have made x equal 54 and y equal 71. B. He should have added the values in the numerator before dividing by 2. C. He should have divided the 71 by 2 instead of the 27. D. He should have made the numerator 76 + 59.
Answers
Given:
The expression is which gives an estimate of how tall Justin will be as an adult is
\(\dfrac{x+y+5}{2}\)
where, x and y are his parents’ current heights in inches.
Mom’s height = 54 inches Dad’s height = 71 inches.
His calculation:
\(\dfrac{71+54+5}{2}=71+27+5=103\ inches\)
To find:
Justin's mistake.
Solution:
Let x be Dad’s height and y be Mom’s height. So, correct estimation for his height is
\(\dfrac{71+54+5}{2}=\dfrac{130}{2}\)
\(\dfrac{71+54+5}{2}=65\)
He should have added the values in the numerator before dividing by 2.

So to find the missing side we can use the pythagorean formula to do this. It must be a right angle triangle if we want to use the formula. So we know two of the side lengths and that, that it has a right angle. Let's do it real quick! The formula is:
c^2=a^2+b^2 (c, the missing side, a is any side, b is the other side length)
So in this one we will find the missing side which is c . . . Place the formula!

The scale factor of two similar hexagons is 3:7.
The area of the smaller hexagon is 18 m2.
What is the volume of the larger hexagon?
Question 7 options:
5832 m2
36 m2
42 m2
324 m2
98 m2
Answers
Since the two hexagons are similar, their corresponding sides are in the same ratio as the scale factor.
Let x be the length of a side of the smaller hexagon, then the corresponding length of a side of the larger hexagon can be expressed as (3/7)x.
The area of a hexagon can be calculated using the formula: A = (3√3/2)s², where s is the length of a side.
Since the area of the smaller hexagon is 18 m², we can solve for x as follows:
18 = (3√3/2)x²
x² = 12/√3
x = 2√3
Now we can calculate the area of the larger hexagon:
Area of the larger hexagon = (3√3/2)(3/7x)² = (3√3/2)(3/7(2√3))² = 54/49 m²
Finally, we can calculate the volume of the larger hexagon, assuming it is a regular hexagonal prism:
Volume of the larger hexagon = Area of hexagon x Height
The height of the hexagonal prism is the same as the length of the side of the larger hexagon, which is (3/7)x:
Volume of the larger hexagon = (54/49) x (3/7)x = 54/343 x² ≈ 0.212 x²
Substituting the value of x, we get:
Volume of the larger hexagon ≈ 0.212 x (2√3)² = 1.272 m³
Therefore, the volume of the larger hexagon is approximately 1.272 m³.
Well, I'm not sure if it's correct but I got 42.
I got this by doing something along the lines of:
1) 18/x = 3/7
2) Cross multiply
3) 3x = 126
4) Divide both sides by 3
5) x = 42

You are standing on a ledge and throw a ball from 10 feet above the ground. The speed the ball leaves your hand is 16 feet per second and the acceleration of gravity is -16 feet per second squared.
1. How many seconds does it take to reach the highest point (vertex)?
Answers
It takes 1 second for the ball to reach its highest point.
What is acceleration of gravity?Acceleration of gravity is the acceleration by which earth pulls
objects towards itself. Acceleration is the rate of change of speed.
Given,
The initial velocity of the ball = 16 feet/second
The initial height of the ball = 10 feet
The ball will first travel upward with an initial velocity of 16 feet/second
and the ball will reach a height of x feet from the point of release. After
that the ball will travel a total downward distance of (10+16) = 26 feet.
At highest point, velocity=0.
Applying, v = u + at
0 = 16 + (-16)t
t = 16/16
t = 1 second
Hence, the ball will take 1 second to reach the highest point.

ou need to rent a truck for one day to move to a new house. uhaul charges $50 a day plus $0.99 per mile. to rent the same size truck from penske will cost $350 a day with no mileage charge. at how many miles will both companies have the same total cost? round your answer to the nearest whole number if needed.
Answers
The miles will be around 303 miles, both Uhaul and Penske will have the same total cost.
To determine at what point both companies have the same total cost, we need to set up an equation.
Let x be the number of miles driven.
For Uhaul, the cost will be $50 + $0.99x.
For Penske, the cost will be $350.
Setting these two expressions equal to each other, we get:
$50 + $0.99x = $350
Simplifying this equation, we get:
$0.99x = $300
U-Haul: Cost_UH = 50 + 0.99 * miles
Penske: Cost_P = 350
Set the equations equal to each other to find the number of miles where the costs are equal.
50 + 0.99 * miles = 350
Solve for the number of miles.
0.99 * miles = 350 - 50 0.99 * miles = 300 miles = 300 / 0.99
Calculate the number of miles and round to the nearest whole number if needed.
miles ≈ 303
So,
At approximately 303 miles, both companies will have the same total cost for renting a truck for one day.
Dividing both sides by $0.99, we get:
x ≈ 303.03
It is important to note that this calculation assumes that the only cost for Uhaul is the rental fee and mileage charge, and does not include any additional fees or charges that may be incurred during the rental period.
It is also important to consider other factors such as the availability of trucks, customer service, and any additional services offered by the rental companies before making a final decision.

Write the equation of the line that goes through (4,5)
and (8,7).
a)x+5 a) y = 1/2x+4,5
b) y = /2x+3
c) y=2x-4.5
d) y=2x-3
Answers
To find the equation of a line that goes through two points, you can use the slope-intercept form of the equation of a line, which is:
y = mx + b
where "m" is the slope of the line and "b" is the y-intercept (the point where the line crosses the y-axis).
To find the slope of the line, you can use the formula:
m = (y2 - y1) / (x2 - x1)
where (x1, y1) and (x2, y2) are two points on the line.
In this case, we are given the points (4, 5) and (8, 7), so we can plug these values into the formula for the slope:
m = (7 - 5) / (8 - 4)
= 2 / 4
= 1/2
Now that we know the slope of the line, we can use the point-slope form of the equation of a line to find the equation of the line:
y - y1 = m(x - x1)
where (x1, y1) is any point on the line and "m" is the slope of the line.
In this case, we are given the point (4, 5), so we can plug these values into the formula:
y - 5 = (1/2)(x - 4)
y = (1/2)x + 3
So, the equation of the line that goes through (4,5) and (8,7) is y = (1/2)x + 3.
Therefore, the correct answer is (b) y = /2x+3.
