Answer:
What does x=
Solve for x
x=25
Answer:
Step-by-step explanation:
(5x+10)+(2x-5)= 180°
first we simplify as much as possible
so, we can add 5x + 2x to get 7x
then we do 10-5 which equals 5.
now we have
7x+5=180
subtract 5 from both sides
7x= 175
x=25
now we input x into <ABD
5x+10
5(25)+10
125+10
130
<ABD=130°

A children's pony ride at a zoo has ponies attached to a carousel pole in the center of a circle. The diameter of a circle is 25 feet. How many feet does a pony walk to complete one trip around the circle?
A pony walks approximately 78.4 feet to complete one trip around the circular pony ride.
What is the distance around the circular pony ride?A circle is simply a closed 2-dimensional curved shape with no corners or edges.
The circumference of a circle or the distance around the circle is expressed mathematically as;
C = 2πr or C = πd
Where r is radius, d is diameter and π is constant pi ( π = 3.14 ).
The distance traveled by a pony to complete one trip around the circle is equal to the circumference of the circle.
Given that the diameter of the circle is 25 feet, we can calculate the circumference using the above formula as follows:
C = πd
C = 3.14 × 25 feet
C = 78.5 feet.
Therefore, the measure of the circumference is approximately 78.5 feet.

Answer:
$(80.5x + 69)
Step-by-step Explanation:
Recall, distributive property of multiplication can simply be expressed as follows, x(y + z) = xy + xz or x(y - z). Where x, y, and z could be any number.
Now, let's use the distributive property to show the total costs of plants Gloria decides to buy as an expression and also simplify it.
Thus, Gloria buys:
4 ferns = 4(0.5x - 3) = 4(0.5x) - 4(3) = $(2x - 12)
2 palms = 2(10x - 2.50) = 2(10x) - 2(2.50) = $(20x - 5.00)
10 lilies = 10(5 + 0.25x) = 10(5) + 10(0.25x) = $(50 + 2.5x)
8 shrubs = 8(4.50 + 7x) = 8(4.50) + 8(7x) = $(36 + 56x)
Total cost of the plants = (2x - 12) + (20x - 5) + (50 + 2.5x) + (36+ 56x)
Open the parentheses and then simplify:
Total cost = 2x - 12 + 20x - 5 + 50 + 2.5x + 36 + 56x
= 2x + 20x + 2.5x + 56x - 12 - 5 + 50 + 36
Total cost = $(80.5x + 69)

how to solve −13x + 46 > −45
Inequality: In mathematics, an inequality is a statement that compares two values, expressions, or quantities using a relation symbol such as "greater than" (>), "less than" (<), "greater than or equal to" (≥), "less than or equal to" (≤), or "not equal to" (≠). An inequality indicates that the values or expressions being compared are not equal.
Combining like terms: In algebra, combining like terms refers to the process of simplifying an expression by adding or subtracting terms that have the same variable raised to the same power.
Inverse operations to isolate: In algebra, inverse operations are operations that undo each other. For example, addition and subtraction are inverse operations, as are multiplication and division. To isolate a variable in an equation or inequality, you can use inverse operations to undo the operations that are being performed on the variable.
To solve the inequality -13x + 46 > -45, you need to isolate the variable (x) on one side of the inequality.
1. First, you can subtract 46 from both sides of the inequality to get:
\(-13x > -91\)
2. Then, divide both sides of the inequality by -13 (remember that when you divide or multiply by a negative number, you need to flip the inequality sign) to get:
\(x < 7\)
Therefore, the solution to the inequality is x < 7. To check, you can substitute any value less than 7 into the inequality to see if it's true. For example, if you plug in x = 5, you get:
\(-13(5) +46 > -45\)
\(-19 > -45\)
This is true, so x < 7 is indeed a valid solution to the inequality.
Which statement accurately describes the proportions in the tails of a normal distribution?
a. Proportions in both the left-hand and right-hand tails tend to be relatively small.
b. Proportions in both the left-hand and right-hand tails tend to be relatively large.
c. The proportion in the left-hand tail is larger than the proportion in the right-hand tail.
d. The proportion in the right-hand tail is larger than the proportion in the left-hand tail.
a. Proportions in both the left-hand and right-hand tails tend to be relatively small.
The correct answer is: a. Proportions in both the left-hand and right-hand tails tend to be relatively small. This is because a normal distribution is symmetric and bell-shaped, with the majority of the data concentrated around the mean. As a result, the tails of the distribution have fewer data points and smaller proportions compared to the center. This is because a normal distribution is symmetric and bell-shaped, with the majority of the data concentrated around the mean.
So, a. Proportions in both the left-hand and right-hand tails tend to be relatively small.

Ixl dilations-find the scale factor and center dilation
The scale factor is 2 and center dilation is reduced.
The scale factor is a ratio that describes how much a figure has been enlarged or reduced. It is calculated by dividing the length of the corresponding sides of the original and dilated figures. If the scale factor is greater than 1, then the figure is enlarged, and if it is less than 1, then the figure is reduced.
To find the scale factor in an IXL dilations problem, you need to compare the corresponding sides of the original and dilated figures.
If the original figure has a side length of 4 units, and the dilated figure has a corresponding side length of 8 units, then the scale factor is 8/4=2. This means that the dilated figure is twice as large as the original figure.
The center of dilation is the point about which the figure is enlarged or reduced. It is the fixed point that remains unchanged during the dilation process.

use the product, quotient, and power rules of logarithms to rewrite the equation as a single logarithm.
We are given the following expression:
\(\log a-3\log b+4\log c\)we are asked to simplify this expression. To do that we will first use the following property:
\(a\log b=\log ^{}b^a\)we will apply this to the second and third terms, like this:
\(\log a-\log b^3+\log c^4\)Now we will use the following property:
\(\log a-\log b=\log (\frac{a}{b})\)we will use this property for the first and second terms:
\(\log (\frac{a}{b^3})+\log c^4\)Now we will use the following property:
\(\log a+\log b=\log ab\)We will use the property in the last two terms, like this:
\(\log (\frac{ac^4}{b^3})\)And thus, we have simplified the logarithmic expression into one single logarithm
Which of the following characteristics does not apply to a theoretical normal distribution? A) It is never negative. B) It is bell-shaped. C) It is bimodal. D) The mean, median, and mode are equal.
The characteristic that does not apply to a theoretical normal distribution is C) It is bimodal.
The main answer is C. An explanation for this is that a normal distribution has a single peak at the mean, and as we move away from the mean in either direction, the frequency of occurrence decreases.
Therefore, a normal distribution can never have two distinct peaks, making it impossible for it to be bimodal. All other options are characteristics of a normal distribution. In conclusion, a theoretical normal distribution is never negative, bell-shaped, and has equal mean, median, and mode, but it is not bimodal.

A rectangle has sides of length 4cm and 8cm. What is the dot
product of the vectors that represent the diagonals?
The dot product of the vectors representing the diagonals is -16. Answer: -16.
Let A and C be the two endpoints of the rectangle. Then, AC = 8 cm is the longer side. The midpoint of AC is M, which is the intersection of its perpendicular bisectors.
Therefore, the length of the shorter side of the rectangle is half of the length of AC, i.e.,
MC = 4 cm.
Now, let's move on to calculate the dot product of the vectors representing the diagonals. AD and CB are the two diagonals of the rectangle that pass through its midpoint M.
Then, the vector representing the diagonal AD can be written as the difference between its two endpoints A and D, i.e.,
AD = D - A = (MC + AB) - A
= C - M + B
= CB + BA - 2MC,
where AB is the vector that points from A to B.
Similarly, the vector representing the diagonal CB can be written as
CB = A - M + D
= BA + AD - 2MC.
Substituting for AD and CB in the dot product, we get AD .
CB = (CB + BA - 2MC) . (BA + AD - 2MC)
= CB . BA + CB . AD - 2CB . MC + BA . AD - 2BA . MC - 4MC²
= (A - M + D) . (B - A) + (A - M + D) . (D - A) - 2(A - M + D) . MC + (B - A) . (D - A) - 2(B - A) . MC - 4MC²
= AB² + CD² - 4MC² - 2(A - M) . MC - 2(D - M) . MC
= AB² + CD² - 4MC² - 2AM . MC - 2DM . MC.
Since the diagonals of a rectangle are equal, we have AD = CB. Therefore, AD . CB = AB² + CD² - 4MC² - 2AM . MC - 2DM . MC
= 64 + 16 - 16 - 2(4)(4) - 2(8)(4)
= - 16.
The dot product of the vectors representing the diagonals is -16. Answer: -16.

For fixed population standard deviation and level of significance, the minimum sample size needed to guarantee a given margin of error ___________- as the margin of error increases.
For fixed population standard deviation and level of significance, the minimum sample size needed to guarantee a given margin of error decreases as the margin of error increases.
The square root of the variance for the given set of numbers is what the standard deviation examines. It is employed to compute a confidence interval for making judgments (such as accepting or rejecting a hypothesis).
Here, the population standard deviation, and level of significance are the same.
As the margin of error increased.
So, with the increase in the value of the margin of error, there will surely decrease in the value of the sample size
\($$\begin{aligned}&\mathrm{MOE}_\gamma=z_\gamma \times \sqrt{\frac{\sigma^2}{n}}\\&\begin{aligned}\mathrm{MOE} & =\text { margin of error } \\\gamma & =\text { confidence level } \\z_\gamma & =\text { quantile } \\\sigma & =\text { standard deviation } \\n & =\text { sample size }\end{aligned}\end{aligned}$$\)
