Complete the inequality so that it represents the whole-number values that side a could be to create a triangle.

the equation √x = -7 has no real solutions.

Why it is?

There is no real number x that satisfies the equation √x = -7.

The square root of a non-negative real number is always non-negative. Therefore, √x is non-negative for all real numbers x, including x = 0. However, -7 is negative, so the equation √x = -7 has no real solutions.

An equation is a statement that asserts the equality of two mathematical expressions. It generally consists of two sides, left-hand side (LHS) and right-hand side (RHS), which are separated by an equal sign (=). An equation is true when both the LHS and RHS represent the same value or expression.

The perimeter of the triangle is 28.08 units, the area of the triangle is 8.49 square units, and the height of the triangle is 3.18 units.

The lengths of the triangle's sides must be determined using the distance formula in order to determine the triangle's perimeter:

Side X to Y length: [tex]\sqrt{(5-2)2 + (9-10)2}[/tex]]d(XY) equals sqrt[9+1] = sqrt (10)

Side Y to Z length: [tex]d(YZ) = \sqrt{[(1-9)2 + (6-5)2]} = \sqrt{65}[/tex]

Side Z to X length: [tex]\sqrt{(2-6)2 + (10-1)2]} = d(ZX) = \sqrt{16+81]} = \sqrt{97}[/tex]

Perimeter: (XY + YZ + d) (ZX)

Sqrt(10) + Sqrt(65) + Sqrt Equals the circumference (97)

Radius = 10.17 + 8.06 + 9.85

Diameter: 28.08

We can apply the following formula to determine the triangle's area:

(1/2) * Base * Height = Area

Every triangle side's length serves as the base. Using side YZ

sqrt = base (65)

We must drop a perpendicular from vertex X to side YZ in order to get the height. The height of the triangle equals the length of this perpendicular.

y - 9 = (1/5) is the equation of the line connecting points Y and Z. (x - 6)

y - 10 = (-5) is the equation for the line that is perpendicular to this line and passes through point X. (x - 2)

We may get the location of the perpendicular's intersection with side YZ by solving these two equations:

x = 3.08, y = 6.47

Hence, the distance between points X and the point of intersection on side YZ is the triangle's height:

height is equal to sqrt[(3.08-2)2 + (6.47-9)2] = sqrt[10.11] = 3.18.

Area = (1/2)*base*height*sqrt(65)*3.18 Area = (1/2)*base*height*area Area = 8.49

We can say that approximately 48 villagers (40% of 120) are under the age of 25. This means that just under half of the population in this village is under the age of 25.

According to the pie chart, we can see that the village of 120 people has 20% of its population over the age of 60. To determine the exact number of villagers over 60, we can multiply the total population by the percentage of people over 60:

120 x 20% = 24

So there are 24 villagers over the age of 60 in this village.

As for the percentage of villagers under the age of 25, we can see from the pie chart that 40% of the population falls into this category. However, it is important to note that the question mentions a village of 120 people, while the percentage given in the chart may not reflect this exact number.

Step-by-step explanation:

The cost of one package of tulip bulbs is 11, and the cost of one package of crocus bulbs is 16.

To find the cost of one package of tulip bulbs and one package of crocus bulbs, follow these steps:

Write two equations based on the given information:

Equation 1 (James): 3T + 7C = 145

Equation 2 (Kim): 10T + 14C = 334

Solve the system of equations using the substitution or elimination method. In this case, we'll use the elimination

method by multiplying Equation 1 by 2 to make the coefficients of C the same:

Equation 1 modified: 6T + 14C = 290

Subtract Equation 2 from the modified Equation 1:

(6T + 14C) - (10T + 14C) = 290 - 334
  -4T = -44

Divide both sides by -4 to find the value of T (tulip bulbs):
  T = 11

Substitute the value of T back into Equation 1 to find the value of C (crocus bulbs):
  3(11) + 7C = 145
  33 + 7C = 145

Subtract 33 from both sides:
  7C = 112

Divide both sides by 7 to find the value of C:
  C = 16

So, the cost of one package of tulip bulbs is 11, and the cost of one package of crocus bulbs is 16.

To find the inverse of the function y = 3x, we need to swap the positions of x and y and then solve for y.

Step 1: Swap the positions of x and y

x = 3y

Step 2: Solve for y

Divide both sides by 3

x/3 = y

So the inverse function of y = 3x is x/3.

We can also verify that this is the inverse function by plugging in x/3 for y in the original equation and confirming that we get x:

y = 3x

x/3 = 3x/3

x/3 = x

Therefore, the inverse function of y = 3x is x/3.

Answer:

Step-by-step explanation:

The given function is y = 3x.

To find its inverse, we start by swapping x and y in the equation to get:

x = 3y

Next, we solve this equation for y to isolate it:

y = x/3

Therefore, the inverse of y = 3x is y = x/3.

After 3 weeks, the dog consumed 3 pounds of food, leaving 7 pounds of food left. Subtracting the amount of food consumed from the initial amount, 10 pounds - 3 pounds = 7 pounds.

After 3 weeks, the dog would have consumed 3 pounds of food (1 pound per week x 3 weeks = 3 pounds).

To find out how many pounds of food are left, we can subtract the amount of food consumed from the initial amount:

10 pounds - 3 pounds = 7 pounds

So there are 7 pounds of food left after 3 weeks.

Expressed in decimal form, it would be 7.0 pounds.

Using the radians we know that the length of the arc in terms of π is s = 1.53 * π * 12 ft or s = 57.60 ft.

All points in a plane that are at a specific distance from a specific point, the center, form a circle.

In other words, it is the curve that a moving point in a plane draws to keep its distance from a specific point constant.

So, the central angle of degrees must first be converted to radians.

θ(rad) = 275/180 * π = 1.53 rad

Then, by multiplying the Central angle (in rad units) by the circle radius r, the arc length may be determined:

s = θ * r

Changing the θ and r values:

s = 1.53 * π * 12 ft

s = 57.60 ft

y = - 2x + 12

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = [tex]\frac{1}{2}[/tex] x + 1 ← is in slope- intercept form

with slope m = [tex]\frac{1}{2}[/tex]

given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{\frac{1}{2} }[/tex] = - 2 , then

y = - 2x + c ← is the partial equation

to find c substitute (6, 0 ) , the point it crosses on the x- axis into the partial equation.

0 = - 2(6) + c = - 12 + c ( add 12 to both sides )

12 = c

It is given to us that Jordan received $100 for a graduation present and deposited it in a savings account. Each week thereafter, he added $15 to the account but no interest was earned.

We need to write an equation represents the relationship between w, the number of weeks Jordan kept his money in the account, and t, the total amount in the savings account:

Graduation present = $100

Amount deposited per week = $15

Let, w be the number of weeks, and t, the total amount in the savings account, therefore, the function is:

Step-by-step explanation:

Sophie deposited approximately $16,516.

The digits 0, 1, 2, 3, 4, 5, 6, 7, 8, and so forth are known as whole numbers. They are the figures we use to measure things, such as the quantity of pencils in a box or apples in a basket. In computations like addition, subtraction, multiplication, and division, whole numbers are also employed.

Let's call the amount Sophie deposited "P". After 9 years, the investment would have gone through 18 compounding periods (2 per year for 9 years).

The formula for calculating the future value (FV) of an investment with compound interest is:

[tex]FV = P(1 + r/n)^{(nt)[/tex]

where:

P = the principal (the initial amount invested)

r = the annual interest rate (as a decimal)

n = the number of times the interest is compounded per year

t = the number of years

In this case, we have:

P = unknown (what we're trying to find)

r = 4.2% = 0.042

n = 2 (since the interest is compounded semiannually, or twice a year)

t = 9

So the formula becomes:

[tex]24,575.22 = P(1 + 0.042/2)^{(2*9)[/tex]

Simplifying the right side of the equation:

24,575.22 = P(1.021)¹⁸

24,575.22 = 1.485P

Dividing both sides by 1.485:

P ≈ $16,516

The probability of running out of anchovies before the evening is over is approximately 0.058, or 5.8%. We must presume that the number of pizzas ordered with anchovies follows a binomial distribution with parameters n = 60 (the total number of pizzas) and p = 0.08 in order to answer this issue using the normal approximation for the binomial distribution. (the probability of ordering anchovies on a pizza). 

The standard deviation of this binomial distribution is given by = sqrt(np(1-p)) = sqrt(60 x 0.08 x 0.92) = 2.03, and the mean is given by = np = 60 x 0.08 = 4.8.

Now, we need to determine the likelihood that we will need to prepare more than eight anchovy-topped pies before the evening is through in order to determine the likelihood that we will run out of anchovies. (since we only have enough anchovies for 8 pizzas).

This is equivalent to finding the probability that the number of pizzas with anchovies is greater than 8, or P(X > 8), where X is the number of pizzas with anchovies.

To use the normal approximation for the binomial distribution, we need to standardize the variable X using the standard normal distribution. This gives us:

z = (X - μ) / σ = (8 - 4.8) / 2.03 = 1.57

Using a standard normal table or calculator, we can find the probability that z is greater than 1.57, which is approximately 0.058. Therefore, the probability of running out of anchovies before the evening is over is approximately 0.058, or 5.8%.

The 95% confidence interval for the mean difference in the amount absorbed is (0.01, 3.25) ml, with a df of 28. Yes, the interval does not contain zero, suggesting that there is a significant difference between the two brands in the amount absorbed.

To find the 95% confidence interval for the mean difference in the amount absorbed, we can use the formula:

CI = (x1 - x2) ± tα/2 * SE

where x1 - x2 is the difference in means, tα/2 is the critical value from the t-distribution table for a 95% confidence interval with degrees of freedom (df) = 30 - 2 = 28 (assuming equal variances), and SE is the standard error of the difference in means:

SE = sqrt[(s1^2/n1) + (s2^2/n2)]

Plugging in the values, we get:

x1 - x2 = 15.63 - 14 = 1.63

s1 = 3.12, n1 = 16

s2 = 2.53, n2 = 16

SE = sqrt[(3.12^2/16) + (2.53^2/16)] = 0.974

tα/2 for df = 28 and α = 0.05 is 2.048.

CI = (1.63) ± (2.048 * 0.974) = (0.01, 3.25)

Therefore, the 95% confidence interval for the mean difference in the amount absorbed is (0.01, 3.25), with df = 28.

This interval suggests that there is a significant difference between brands in the amount absorbed, since the interval does not include 0. This means that we can reject the null hypothesis that the means are equal at a 5% significance level and conclude that the mean amount of water absorbed for brand A is significantly greater than brand B.
