Answer:
This is a normal distribution and we can use the standard score to compute for probabilities. We compute the standard score of the given.
Explnation:
z = (x - mu)/sd
z = (2625 - 2600)/50 = 25/50 = 0.5.
Consulting the z-table, P(z <= 0.5) = 0.6915.
P(z > 0.5) = 1 - P(z <= 0.5) = 1 - 0.6915 = 0.3085.

Simplify the following rational expression. Be sure to state the condition.
The simplified form of the rational expression (x²+5x+6)/(3x+6) is (x+3)/2.
And we used factorization to find the simplified form.
What is factorization?Factorization is a process to simplify the expression by finding the factors of that expression.
And to find the same expression from factors, you have to reverse the process.
Given:
The rational expression,
(x²+5x+6)/(3x+6).
Simplifying,
the expression using factorization method.
First, (x²+5x+6),
= x²+2x+3x+6
= x(x+2)+3(x+2)
= (x+2) (x+3)
And 3x+6 = 3(x+2)
Substituting the simplified values to the given expression,
(x²+5x+6)/(3x+6),
= (x+2) (x+3) / {3(x+2)}
Factor out the common factor,
= (x+3)/2
Therefore, the simplified form is (x+3)/2.

Step-by-step explanation:
From the question, we can deduce that the algebraic expression is a multiplication of a number and a variable.
First instance;
Number = +1
variable= x
Output = -4
+1 * x = -4
x = -4/1 = -4
Second instance;
Let the unknown number be y.
Number = y

Find the equation of the line in slope-intercept form through the point (-6,4) and Perpendicular to the line y = -1/2x + 8
Answer:
y = 2x + 16
Step-by-step explanation:
Remember: The slope of perpendicular lines are negative reciprocals of each other.
1. Find the slope using the given equation.
y= -1/2x + 8 Using the slope- intercept form y = mx + b, the slope is -1/2 because it is the coefficient of the x-term .
The new line is perpendicular to the given line and their slopes are negative reciprocals of each other. You will use a slope = 2
2. Substitute into the slope intercept form y = mx +b , the value of the slope, "m" and the given point (-6, 4) and solve for "b"
y = mx + b
4 = 2(-6) + b
4 = -12 + b
16 = b
3. General form of slope intercept form: y = 2x +16

The value of X when <1 = 3x+15 = 25. Then the value of the missing part of the sides of the kite (KITE) is given as follows;
X = 25
a.) ET = 60
b.) KE = 20
How to calculate the missing parts of the KITE?One of the properties of a kite is that it has two pairs of adjacent equal sides and the longer diagonal bisects the shorter one with the formation of angle 90°.
Therefore to calculate for X when <1 = 3x+15 is as follows;
<1 = 90°
90= 3x+15
3x = 90-15
3x = 75
X = 75/3
X = 25
But IT = ET
Given IT = 2x +20
X = 25
IT = ET = 2(20)+20
= 40+20 = 60
But KI = KE
Given that KI = 2x-30
X = 25
KI= KE = 2(25)-30
= 50-30 = 20

a. The center of the circle is (-2, -1).
b. The radius of the circle is √136.
c. The equation of the circle is (x + 2)^2 + (y + 1)^2 = 136.
a. To find the center of the circle, we can use the midpoint formula, which states that the midpoint of a line segment with endpoints (x1, y1) and (x2, y2) is given by:
Midpoint = ((x1 + x2)/2, (y1 + y2)/2)
In this case, the endpoints of the diameter are P(-7, -4) and Q(3, 2).Applying the midpoint formula:
Midpoint = ((-7 + 3)/2, (-4 + 2)/2)
= (-4/2, -2/2)
= (-2, -1)
Therefore, the center of the circle is at the coordinates (-2, -1).
b. To find the radius of the circle, we can use the distance formula, which calculates the distance between two points (x1, y1) and (x2, y2). The radius of the circle is half the length of the diameter, which is the distance between points P and Q.
Distance = √\([(x2 - x1)^2 + (y2 - y1)^2]\)
Using the distance formula:
Distance = √[(3 - (-7))^2 + (2 - (-4))^2]
= √\([(3 + 7)^2 + (2 + 4)^2]\)
= √\([10^2 + 6^2\)]
= √[100 + 36]
= √136
Therefore, the radius of the circle is √136.
c. The equation for a circle with center (h, k) and radius r is given by:
\((x - h)^2 + (y - k)^2 = r^2\)
In this case, the center of the circle is (-2, -1), and the radius is √136. Substituting these values into the equation:
\((x - (-2))^2 + (y - (-1))^2\) = (√\(136)^2\)
\((x + 2)^2 + (y + 1)^2 = 136\)
Therefore, the equation of the circle is (x + 2)^2 + (y + 1)^2 = 136.

A shipping company charges an oversize package fee if the sum of the
dimensions of the package are more than 60 in. The length of the package you
want to send must be twice its width. What are the dimensions of a package
with maximum volume that avoids the oversize fee?
Answer: Length = 40 inches
Width = 20 inches
Step-by-step explanation:
Let the width of the package be represented by x.
Since the length of the package must be twice its width, therefore the length will be: = 2 × x = 2x
Since the sum of the dimensions equals 60 inches. This will then be:
x + 2x = 60.
3x = 60
x = 60/3
x = 20
Therefore, the width = 20 inches
Length = 2x = 2 × 20 = 40 inches
The dimensions should be 40 by 20 inches.

a. m<A = 38°; b. m(CE) = 56°; c. m<C = 38°; d. m<D = 39°;
e. m<ABE = 67°
How to Find Each Indicated Measure for the Circle?In order to find the indicated measures in the circle, recall that the measure of an inscribed angle is half of the measure of the intercepted arc based on the inscribed angle theorem.
Thus, we have:
a. m<A = 1/2(m(BD))
Substitute:
m<A = 1/2(76)
m<A = 38°
b. m(CE) = 2(m<CBE))
Substitute:
m(CE) = 2(28)
m(CE) = 56°
c. m<C = 1/2(m(BD))
Substitute:
m<C = 1/2(76)
m<C = 38°
d. m<D = 1/2(m(AC))
Substitute:
m<D = 1/2(78)
m<D = 39°
e. m<ABE = 1/2(m(ACE))
m<ABE = 1/2(m(AC) + m(CE))
Substitute:
m<ABE = 1/2(78 + 56)
m<ABE = 67°

b. 150 milliliters of the first brine solution, 850 milliliters of the second brine solution
Oc. 100 milliliters of the first brine solution, 900 milliliters of the second brine solution
O d. 200 milliliters of the first brine solution, 1,000 milliliters of the second brine solution
e. 900 milliliters of the first brine solution, 100 milliliters of the second brine solution
Using proportions, it is found that the correct option is:
c. 100 milliliters of the first brine solution, 900 milliliters of the second brine solution
The 1-liter solution, with 23.5% salt, is composed by:
x liters of the first brine solution, with 10% salt.1 - x liters of the second brine solution, with 25% salt.Hence, the combined equation is:
\(0.1x + 0.25(1 - x) = 0.235\)
\(0.1x + 0.25 - 0.25x = 0.235\)
\(0.15x = 0.015\)
\(x = \frac{0.015}{0.15}\)
\(x = 0.1\)
Hence, 0.1L = 100 mL of the first solution, 900 mL of the second, and option c is correct.

First, subtract both sides by 10x.
\( \displaystyle \large{10x - 10x+ 8 = 11x - 10x - 8} \\ \displaystyle \large{8= x- 8}\)
Then add both sides by 8 to isolate x-term.
