Answer:
The value is c = 21.1445.
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
The weight distribution of parcels sent in a certain manner is normal with mean value 12lb and standard deviation 3.5 lb.
This means that [tex]\mu = 12, \sigma = 3.5[/tex]
What value of c is such that 99% of all parcels are at least 1 lb under the surcharge weight?
This 1 added to the value of X for the 99th percentile, which is X when Z has a p-value of 0.99, so X when Z = 2.327.
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]2.327 = \frac{X - 12}{3.5}[/tex]
[tex]X - 12 = 2.327*3.5[/tex]
[tex]X = 20.1445[/tex]
1 + 20.1445 = 21.1445
The value is c = 21.1445.

Answer:
Angle 2 = 124 degrees
Step-by-step explanation:
Angles 1 and 2 are corresponding angles since the two lines are parallel.
We can put both numbers into an equation.
3x + 25 = 2x + 58
Subtract both sides by 2x which will give:
x + 25 = 58
Now, we can solve for x, which is:
x = 58-25 = 33
Put back x = 33 into angle 2.
Hence, angle 2 is 2*33 + 58 = 124
Answer:
m∠2 = 124 degrees
Step-by-step explanation:
By the definition of "Same Side Corresponding Angles" the 2 angles given are congruent to each other, therefore we can say;
3x + 25 = 2x + 58
x + 25 = 58
x = 58 - 25
x = 33
Now that we have x = 33, we can substitute 33 in for x, in equation given for angle 2 to find it's measure;
∠2 = 2(33) + 58
∠2 = 66 + 58
∠2 = 124
Therefore m∠2 = 124 degrees.

4x-3=2x+7
Answer:
x = 5
Step-by-step explanation:
Note the equal sign, what you do to one side, you do to the other. Isolate the variable, x.
Add 3 and subtract 2x from both sides of the equation:
4x (-2x) - 3 (+3) = 2x (-2x) + 7 (+3)
4x - 2x = 7 + 3
2x = 10
Next, isolate the x by dividing 2 from both sides of the equation:
(2x)/2 = (10)/2
x = 10/2
x = 5
5 is your answer for x.

Answer:
x=5
Step-by-step explanation:
4x-3=2x+7
Subtract 2x from each side
4x-2x-3=2x-2x+7
2x -3 = 7
Add 3 to each side
2x-3+3=7+3
2x = 10
Divide by 2
2x/2 =10/2
x = 5

Perimeter of 30 ft in an area of 14 ft what is the length and the width
Answer:
14 and 1
Explanation:
14 + 14 + 1 + 1 = 30
14 x 1 = 14
The perimeter is the sum of all 4 sides. Divide the perimeter in half fo the some of one length and one width:
Length + width = 15
Area is length x width
Find 2 numbers that when added equal 15 but when multiplied equal 14
15 + 0 = 15, 15 x 0 = 0
14 + 1 = 15, 14 x 1 = 14
The answer is 14 ft long by 1 ft wide

Find f(-2) for f(x) = 5.34.
Answer:

A laundry basket contains 15 socks, of which 5 are yellow.
What is the probability that a randomly selected sock will be yellow?
Write your answer as a fraction or whole number.
Answer:
5/15
Step-by-step explanation:
Out of 15, 5 are yellow. Converted to a fraction this will be 5/15. Hope this helps!! :)
Answer:
1/3
Step-by-step explanation:
Take the total number of socks and compare it to the number of yellow socks. 15 and 5. Now divide the total by the specified group (yellow socks), by doing so, you get 3.
Every 1 in 3 socks is yellow, meaning the chance of picking a yellow sock at random is 1/3.

1. Write an equation to determine the height, h, of the building.
Answer: 5^2 +h^2 = 102
2. To the nearest tenth, determine the height of the
building.
Answer:
8.7 m
Step-by-step explanation:
Hi there!
[tex]5^2+h^2=10^2[/tex]
To find the height of the building, we need to isolate h on one side of the equal sign. We will do this by performing inverse operations to both sides (ex. the inverse of addition is subtraction, the inverse of multiplication is division, etc.)
Firstly, we can simplify both sides by squaring 5 and 10:
[tex]25+h^2=100[/tex]
Now subtract both sides by 25 to cancel it out on the left side and isolate h²:
[tex]25+h^2-25=100-25\\h^2=75[/tex]
Now, take the square root of both sides to isolate h:
[tex]\sqrt{h^2} =\sqrt{75} \\h=8.7[/tex]
Therefore, the height of the building is 8.7 m when rounded to the nearest tenth.

What are the zeros of the quadratic function f(x) = 6x2 + 12x-7?
Answer:
[tex]f(x) = 6x ^{2} + 12x - 7 \\ x = \frac{ - 6 + \sqrt{78} }{6} \: , - \frac{ - 6 - \sqrt{78} }{6} [/tex]
Given:
The quadratic function is:
[tex]f(x)=6x^2+12x-7[/tex]
To find:
The zeros of the quadratic function.
Solution:
Quadratic formula: If a quadratic equation is [tex]ax^2+bx+c=0[/tex], then zeros of the quadratic equation are:
[tex]x=\dfrac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]
We have,
[tex]f(x)=6x^2+12x-7[/tex]
For zeros, [tex]f(x)=0[/tex].
[tex]6x^2+12x-7=0[/tex]
Here, [tex]a=6,b=12,c=-7[/tex]. Using quadratic formula, we get
[tex]x=\dfrac{-12\pm \sqrt{(12)^2-4(6)(-7)}}{2(6)}[/tex]
[tex]x=\dfrac{-12\pm \sqrt{144+168}}{12}[/tex]
[tex]x=\dfrac{-12\pm \sqrt{312}}{12}[/tex]
[tex]x=\dfrac{-12\pm 17.6635}{12}[/tex]
Now,
[tex]x=\dfrac{-12+17.6635}{12}[/tex] and [tex]x=\dfrac{-12-17.6635}{12}[/tex]
[tex]x=0.47195833...[/tex] and [tex]x=-2.47195833...[/tex]
[tex]x\approx 0.472[/tex] and [tex]x\approx -2.472[/tex]
Therefore, the zeros of the given quadratic function are 0.472 and -2.472.

Answer:
x = 46.8
Step-by-step explanation:
I assume you are trying to find the value of x.
[tex]5x=234.[/tex]
To find x, divide the answer by the coefficient. The quotient is the value of 'x.'
[tex]234/5=46.8[/tex]
Therefore, 46.8 is the value of x.
