A cell phone company expects that every 2 out of 25 cell phones will have some form of defect. At this rate, how many cell phones out of 500 will be expected to have a defect?
Answers
Answer:
40 phones
Step-by-step explanation:
The company expects that every 2 out of 25 phones will have some form of defect.
In percentage terms, this is:= 2 / 25 * 100%= 8%If there are 500 phones therefore,
the defected phones would still be the same percentage and the actual number would be:= 8 % * 500= 40 phones

A shipping company charges $6 to ship a package that weighs up to 1 pound and $2 for each additional pound or portion of a pound. which equation represents the cost, in dollars, of shipping a package that weighs x pounds?
Answers
The equation is 6(2x-1), where X is more than 0. When a shipping company charges $6 to ship a package that weighs up to 1 pound.
What is the equation?
In algebra, an equation can be defined as a mathematical statement consisting of an equal symbol between two algebraic expressions that have the same value.
A shipping company charges $6 to ship a package that weighs up to 1 pound and $2 for each additional pound or portion of a pound.
lets make an assumption that the total weight of the shipment is x pound and cost for shipping is y.
the shipping company charges $6 for the first pound.
Up to now, the charge is y=6
After 1 pound, i.e for the remaining (x-1) pounds, they charge $2 per pound.
So, the total charge will be, y=6+2(x-1)
weight is always starting from zero as there is no negative weight.so X>0
so the equation is 6(2x-1), where X is more than 0

A triangle with side lengths of 200 meters, 300 meters, and 250 meters is shown. a surveyor measures the lengths of the sides of a triangular plot of land. what is the measure of the angle of the triangular plot at which the surveyor stands? approximate to the nearest degree. cos–1(0.75) = 41° cos–1(0.125) = 83° cos–1(0.563) = 56° cos–1(0.15) = 89°
Answers
The angle of the triangular plot at which the surveyor stands is 83°
What is a triangle?A triangle is a shape with three sides and three angles. From the information given, the sides of the three angles are different, we can say the triangle is a scalene triangle since no sides are equal.
To determine the angle of the triangular plot at which the surveyor stands, we need to use the cosine formula.
Given that:
a = 300 mb = 250 mc = 200 mLet's assume that the angle at which the surveyor stands is ∠A, then:
[tex]\mathbf{a^2= b^2+c^2-2 bc \times Cos A}[/tex]
Making cos A the subject, we have:
[tex]\mathbf{cos \ A = \dfrac{ b^2+c^2-a^2}{2bc}}[/tex]
[tex]\mathbf{cos \ A = \dfrac{ 250^2+200^2-300^2}{2(250 \times 200)}}[/tex]
[tex]\mathbf{cos \ A = 0.125}[/tex]
A = cos⁻¹ (0.125) ≅ 83°

Answers
Answer:
y = (1/4)x + 20
Step-by-step explanation:
The general equation of a line is
y = mx+ b , where m is the slope of the line and b is the y-intercept of the line ( where the line intersects the vertical y-axis)
From the graph we can see that the line intersects the y-axis at 20, so our y- intercept is b = 20
Now will find the slope of the line, and for that we need any two points from the line.
For example let's pick points ( x1= 0, y1 = 20) and ( x2 = 4, y2 = 21)
the slope m = (y2-y1)/(x2-x1) = (21-20)/ (4-0) = 1/4
slope of the line is m = 1/4
The equation of the graph shown in the graph is
y = (1/4)x + 20

What is an Equation of a line?
The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the equation of line be represented as A
Now , the value of A is
Let the first point be P = P ( 3 , 0 )
Let the second point be Q = Q ( 8 , 35 )
Now , the slope of the line between the points is given by the formula
Slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Substituting the values in the equation , we get
Slope m = ( 35 - 0 ) / ( 8 - 3 )
Slope m = 35/5
Slope m = 7
Now , the equation of line is given by the formula ,
y - y₁ = m ( x - x₁ )
Substituting the values in the equation , we get
y - 0 = 7 ( x - 3 )
y = 7x - 21
Now , the initial value of y is calculated when x = 0
So , substituting the value of x = 0 in the equation , we get
y = 7 ( 0 ) - 21
y = -21
Therefore , the initial value of y = -21
Hence , the equation of line is y = 7x - 21

Multiplying a function by a constant has the effect of vertically scaling the graph of the function by a factor equal to that constant.

Here, you're multiplying by 2/3, so each y-value is 2/3 of its previous distance from the x-axis. The effect on the graph of a parabola is to make it "flatter", hence wider in appearance. This does not change the direction in which it opens.

what is the y-intercept of the line given by the equation y=8x +75?
Answers
Answer:
(0, 75)
Step-by-step explanation:
The y-intercept is the y-coordinate of a function when x is equal to 0. In other words, it is the point at which the function crosses the y-axis.
For the equation y = 8x + 75, you plug in x = 0 to get:
y = 8(0) + 75 = 75, meaning that y = 75 when x = 0.
This gives you the y-intercept (0, 75).

You have noticed that because of the pandemic, cycling became popular again
as it became one of the means of transportation for many especially those who
lost their jobs and it became a hobby for some. You became a fan of cycling due
to its influence, so you decided to build your own Mountain bike. You have many
choices to make. First, you must choose the color of your bike from 4 colors (red,
blue, orange, black), second is the seat either normal or with extra cushion and
the last is the handlebar if you want to have a straight one or a curve.
Using the fundamental counting principle, count the number of choices you have
in building your mountain bike?
Answers
Using the Fundamental Counting Theorem, it is found that you have 16 choices in building your bike.
What is the Fundamental Counting Theorem?It is a theorem that states that if there are n things, each with [tex]n_1, n_2, \cdots, n_n[/tex] ways to be done, each thing independent of the other, the number of ways they can be done is:

In this problem:
For the color, there are 4 outcomes, hence [tex]n_1 = 4[/tex].For the seat, there are 2 outcomes, hence [tex]n_2 = 2[/tex].For the handebar, there are 2 outcomes, hence [tex]n_3 = 2[/tex].Thus, the total number of choices is given by:

This is one of those questions where you could solve for h in the formula and then just put values in for all the other variables. Since you have posted this on Brainly, I'll just use the formula given and my last step will be one of division
Formula
S = 2 * pi * r^2 + 2 * pi * r * h Put the givens into the formula
Givens
S = 175 in^2
pi = 3.14
r = 6
h = ?
Solution
175 = 2 * 3.14 * 6^2 + 2 * 3.14 * 6 * h Combine
175 = 226.08 + 37.68*h Subtract 226.08 from both sides
175-226.08 = 37.68*h Combine
-51.08 = 37,68*h Divide by 37.68
h = - 51.08/37.68

PLEASE HELP Evan earned a score of 610 on Exam A that had a mean of 650 and a standard deviation of 40. He is about to take Exam B that has a mean of 600 and a standard deviation of 50. How well must Evan score on Exam B in order to do equivalently well as he did on Exam A? Assume that scores on each exam are normally distributed.
Answers
Using z-scores, it is found that he must score 550 on Exam B order to do equivalently well as he did on Exam A.
What is the z-score formula?The z-score of a measure X of a distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The z-score measures how many standard deviations the measure is above or below the mean.
For Exam A, we have that the parameters are [tex]X = 610, \mu = 650, \sigma = 40[/tex], hence his grade had a z-score given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{610 - 650}{40}[/tex]
[tex]Z = -1[/tex]
In Exam B, with [tex]\mu = 600, \sigma = 50[/tex], we want the grade X with the same z-score of Z = -1, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]-1 = \frac{X - 600}{50}[/tex]
X - 600 = -50
X = 550.
He must score 550 on Exam B order to do equivalently well as he did on Exam A.
