Complete Question
Engineers must consider the breadths of male heads when designing helmets. The company researchers have determined that the population of potential clientele have head breadths that are normally distributed with a mean of 6.4-in and a standard deviation of 0.9-in.If you were to draw samples of size 47 from this population, in what range would you expect to find the middle 50% of most averages for the breadths of male heads in the sample
Answer:
The range is from [tex] \=x_1 = 6.312 [/tex] to [tex] \=x_2 = 6.488 [/tex]
Step-by-step explanation:
From the question we are told that
The mean is [tex]\mu = 6.4 \ in[/tex]
The standard deviation [tex]\sigma = 0.9 \ in[/tex]
The sample size is n = 47
Generally the standard error is mathematically represented as
[tex]\sigma_{\= x} = \frac{0.9}{\sqrt{47} }[/tex]
=> [tex]\sigma_{\= x} = 0.13128 [/tex]
Generally the proportion where the middle 50% of most average for the breaths of male heads in the sample is mathematically evaluated as
[tex]P(\= x_1 < \= X < \= x_2 ) = P(\frac{\=x_1 - \mu }{\sigma_{\= x} } < \frac{\= X - \mu }{\sigma_{\= x} } < \frac{\=x_2 - \mu }{\sigma_{\= x} } ) = 0.5[/tex]
Generally [tex]\frac{\= X - \mu }{\sigma_{\= x} } = Z(The \ standardized \ value \ of \ \= X )[/tex]
So
[tex]P(\= x_1 < \= X < \= x_2 ) = P(\frac{\=x_1 - 6.4}{ 0.13128 } <Z < \frac{\=x_2 - 6.4 }{0.13128} ) = 0.5[/tex]
From the z table the z-score of 0.5 is
[tex]z-score = \pm 0.674[/tex]
So
[tex]\frac{\=x_1 - 6.4}{ 0.13128 } = -0.674[/tex]
[tex] \=x_1 = 6.312 [/tex]
and
[tex]\frac{\=x_2 - 6.4}{ 0.13128 } = 0.674[/tex]
[tex] \=x_2 = 6.488 [/tex]

To trisect an ___ angle you first construct an equilateral triangle.
A. Acute
B. Right
C. 60-degree
D. Obtuse
To trisect a 60-degree angle you first construct an equilateral triangle.
Option C is the correct answer.
What is an angle?The angles between two lines are the angles formed by two intersecting lines, measured in degrees or radians.
Several different types of angles can be formed between two lines, including acute angles, right angles, and obtuse angles.
We have,
To trisect a 60-degree angle, we can use the fact that an equilateral triangle has three 60-degree angles.
The steps to trisect a 60-degree angle using an equilateral triangle are as follows:
Draw an equilateral triangle with one of its vertices at the angle to be trisected.
Draw a line from the vertex of the angle to the opposite side of the triangle, dividing the angle into two 30-degree angles.
Draw a line from the vertex of the angle to the point where the opposite side intersects the circle centered at the vertex with a radius equal to the length of one side of the equilateral triangle. This will divide one of the 30-degree angles into two 15-degree angles.
Draw a line parallel to the opposite side of the triangle from the point where the 15-degree angle is divided to the adjacent side of the triangle. This will trisect the 60-degree angle into three 20-degree angles.
Thus,
By constructing an equilateral triangle, we can trisect a 60-degree angle.

Can zero be a solution of a quadratic equation? Explain
- tysm pooo
Answer:
If the discriminant is less than 0, the equation has no real solution. Looking at the graph of a quadratic equation, if the parabola does not cross or intersect the x-axis, then the equation has no real solution. And no real solution does not mean that there is no solution, but that the solutions are not real numbers. The Zero-Product Property states that for all real numbers a and b, if [tex]ab=0[/tex], then a=0 or b=0.
We can The Zero-Product Property to solve a quadratic equation when we can factor the standard form of the equation. Because when we apply The Zero-Product Property to a factored quadratic equation we can find the x-intercepts of the graph of the related functions. Respectively we can find the solutions to the quadratic equation.

Write a function that models the following description: A man drove a total of 40 miles over a 2-hour period. (1 point)
Answer:
The function is Speed, f(t) = x/t
Step-by-step explanation:
The given information are;
The distance the man drove = 40 miles
The duration of time the man drove = 2-hours
Given that a function maps each item of the input domain to a single item of the output domain, we can have the following relation for the above parameters;
Speed = (Distance travelled)/(Time taken)
Where, speed f(t), is a function of the time taken, t, to travel a distance x
The function is therefore;
Speed, s = f(t) = x/t
Speed = 40/2 = 20 mile per hour.
Answer:
The function is Speed, f(t) = x/t

Diego's club earns money for charity when members of the club perform community service after school,each student who does community service, the club earns $5. There are 12 students in the club,The total dollar amount earned, E. Is a function of the number of members who perform communityservice, n. Is 24 a possible output
Answer:
No
Step-by-step explanation:
Given that:
Amount earned when a student does comminty service = $5
Number of students in club = 12
Amount earned E, is a function of number of members (n) who does community service.
Hence,
E = n * amount earned per member
Is 24 a possible output?
To test, then E = 24
24 = n * 5
24 = 5n
24/5 = 5n/5
4.8 = 5
Hence, 24 is not a possible output, be use number of membwra cannot be a decimal

Solve for x.
50x + 54 = 34x + 46
Answer:
x = -1/2
Step-by-step explanation:
50x + 54 = 34x + 46
Subtract 34x from each side
50x-34x + 54 = 34x-34x + 46
16x +54 = 46
Subtract 54 from each side
16x+54-54 = 46-54
16x = -8
Divide by 16
16x/16 = -8/16
x = -1/2
Answer:
[tex]x=-\frac{1}{2}[/tex]
Step-by-step explanation:
So we are given an equation and we are asked to solve for x.
50x + 54 = 34x + 46
Subtract 54 from both sides.
50x = 34x - 8
Subtract 34x from both sides.
16x = -8
Divide both sides by 16.
[tex]x=-\frac{1}{2}[/tex]
So now we have solved for x. We have found that [tex]x=-\frac{1}{2}[/tex].

A truck is leaving a post office and heading out to deliver mail. The table shows the truck's distance d from the post office at time t. Calculate the average rate of change over the interval from 8 to 15 minutes.
Answer:
1km per minute
Step-by-step explanation:
Given the table in the picture :
The average rate of change over the interval from 8 to 15 minutes will be :
Change in distance / change in time
Change in distance between 8 and 15 minutes :
Distance d1 at 8 minutes t1 = 7km
Distance d2 at 15 minutes t2 = 14km
Average rate of change = (d2 - d1) / (t2 - t1)
Average rate of change = (14 - 7)km / (15 - 8)min
Average rate of change = 7km / 7minutes
Average rate of change = 1km per minute
Answer:
The rate of change is 1 kilometer per minute

The value of the function when x = -2 then g(-2) = 4.
What is a function?A function is defined as a relation between the set of inputs having exactly one output each. The Numbers constants, variables, operations, functions, brackets, punctuation, and grouping can be represented by mathematical symbol.
WE have been given an function as g(x) = 2x² - 4
Now plug the value x = -2 in the given function;
g(-2) = 2(-2)² - 4
g(-2) = 2 x 4 - 4
g(-2) = 8 - 4
g(-2) = 4
Therefore, the value of the function when x = -2 then g(-2) = 4.

Answer:

Step-by-step explanation:
Given
17 ≤ - 3x + 2 ≤ 26 ( subtract 2 from each of the 3 intervals )
15 ≤ - 3x ≤ 24
Divide the 3 intervals by - 3, reversing the symbols as a result of dividing by a negative quantity.
- 5 ≥ x ≥ - 8 , that is
- 8 ≤ x ≤ - 5 → D
[tex]17 \leqslant - 3x + 2 \leqslant 26[/tex]
Subtract sides -2
[tex]17 - 2 \leqslant - 3x + 2 - 2 \leqslant 26 - 2 \\ [/tex]
[tex]15 \leqslant - 3x \leqslant 24[/tex]
Divided sides by -3
=======================================
Point :
When the sides of a inequality multiply or divided by an negative number It changes direction and returns them.
=======================================
Thus ;
[tex] \frac{15}{ - 3} \geqslant \frac{ - 3}{ - 3}x \geqslant \frac{24}{ - 3} \\ [/tex]
[tex] - 5 \geqslant x \geqslant - 8[/tex]
[tex] - 8 \leqslant x \leqslant - 5[/tex]
Thus the correct answer is (( D )) .

Answer:
47°
Step-by-step explanation:
a staight angle equals 180 degrees
180=6x+29+3x+124
x=3
18+29=boc
boc=47
btw, if u know how to do my question could u plz help
thx
Answer: angle BOC is 47°
Step-by-step explanation:
Supplementary angles add to 180°
6x + 29 + 3x + 124 = 180
6x + 3x + 29 + 124 = 180
9x + 153 = 180
9x = 180 -153
9x = 27
x = 3
Substitute 3 for x in ∠BOC = 6x +29
6(3) + 29 = ∠BOC
18 + 29
47° =m∠BOC
