Sales fall from 300 per week to 270 per week what’s the percentage change

Answers

Answer 1

Hi there!

Your question:

Sales fall from 300 per week to 270 per week what's the percentage change?

My answer:

The formula for calculating percent change is as follows:

[(y2 - y1)/y1]*100=your percent change

y2= first value
y1=second value

Plug the numbers in:

[(300-270)/300]*100

[30/300]*100

0.1*100

10

Therefore, the percent change is 10%

Hope this helps! Let me know if it's incorrect so I can fix it:)

ΔRST is dilated about the origin, O, to create ΔR'S'T'. Point R is located at (3, 9), and point R' is located at (1.2, 3.6). Which scale factor was used to perform the dilation?

Answers

a scale factor is a number that u multiply one set of points by to get to the other set...

(3,9)....to (1.2,3.6)

so what are we gonna multiply 3 by to get to 1.2 ? And what are we gonna multiply 9 by to get to 3.6 ? It should be the same number

3x = 1.2 9x = 3.6
x = 1.2/3 x = 3.6 / 9
x = 0.4 x = 0.4

so 3 * 0.4 = 1.2
and 9 * 0.4 = 3.6

so ur scale factor is 0.4 or 2/5

At rugby practice, a group of 8 players stands in a circle and throws the ball from one person to the next. another player is trying to run faster than the ball moves around the circle as it is thrown from one player to the next. After 24 throws, the runner is right next to the ball. If the radius of the circle is 9yd, how many yards has the runner traveled? round your answer to the nearest tenth

Answers

diameter is the radius times 2, which is 18. 18 x 24 = 432 yards

Final answer:

The runner traveled approximately 45.1 yards around the circle during 24 throws at rugby practice.

Explanation:

The runner traveled approximately 45.1 yards.

To solve this, we can consider the circumference of the circle formed by the players, which is 2π times the radius. After 24 throws, the runner would have traveled a distance equivalent to 24 times the circumference of the circle.

So, the total distance the runner traveled would be 24 * (2π * 9) = 24 * 56.5487 = approximately 1357.2yd. Rounding to the nearest tenth, the runner traveled approximately 45.1 yards.

Assume that a researcher randomly selects 14 newborn babies and counts the number of girls selected, x. the probabilities corresponding to the 14 possible values of x are summarized in the given table. find the probability of selecting exactly 4 girls..

Answers

The number of girls in the 14 newborn babies selected is a binomially distributed random variable with n = 14 and p = 0.5. And we know that the binomial probability distribution is given by

P(X = k) = (nCk) p^k (1–p)^(n-k)

So, P(X = 0) = (14C0) • 0.5^0 • (1–0.5)^(14-0) = 0.000

P(X = 1) = (14C1) • 0.5^1 • (1–0.5)^(14–1) = 0.001

And so on.

Thus, P(X = 4) = (14C4) • 0.5^(4 • (1–0.5)^(14–4) = 0.061

So the probability of selecting exactly 4 girls is 0.061.

or, we can write,

= (i^2)^15 . i

Since i^2 = -1

Therefore we can write,

Answers

Final answer:

The slope of 3.41 in the least-squares regression line y = 10.53 + 3.41x indicates that for every one degree Fahrenheit increase in temperature above 50°, the number of cricket chirps per minute is expected to increase by an average of 3.41 chirps.

Explanation:

The slope of the least-squares regression line in the relationship between the number of chirps per minute for crickets (y) and temperature is 3.41. This number represents the average increase in the number of chirp per minute for every degree Fahrenheit that the temperature is above 50°. Therefore, if the temperature increases by one degree Fahrenheit, the expected number of cricket chirps per minute increases by an average of 3.41 chirps.

The slope of the least-squares regression line, which is 3.41, indicates that for every degree Fahrenheit the temperature exceeds 50°, the number of chirps per minute for crickets increases by 3.41 chirps.

In a linear regression equation of the form y = a + bx, the slope (b) represents the change in the dependent variable (y) for a one-unit change in the independent variable (x).

In this context, the slope (b) is 3.41, which means that for each additional degree Fahrenheit above 50°, the model predicts an increase of 3.41 chirps per minute by the crickets.

The intercept of the regression line is 10.53, which represents the baseline number of chirps per minute when the temperature is exactly 50°F.

The complete question is:

A wildlife biologist is interested in the relationship between the number of chirps per minute for crickets (y) and temperature. Based on the collected data, the least-squares regression line is yˆ = 10.53 + 3.41x, where x is the number of degrees Fahrenheit by which the temperature exceeds 50°. Give a sentence that describes the meaning of the slope of the least-squares regression line.

the difference between the measures of two complementary angles is 46. determine the measures of the two angles?

Answers

Let the angle be x . Then its complement is 90-x. So we have

x - (90- x) = 46
x - 90 + x = 46
2x = 46 + 90 = 136
x = 136/2 = 68

x = 68 degrees and its complement = 22 degrees

Final answer:

To determine the measures of two complementary angles with a 46-degree difference, you can set up an equation and solve for the angles, resulting in approximately 22.0 degrees and 68.0 degrees.

Explanation:

Complementary angles are two angles that add up to 90 degrees. If the difference between them is 46 degrees, we can set up an equation to find their measures:

Let one angle be x. The other angle would then be 90 - x.

Given that the difference between them is 46, we have the equation: 90 - x - x = 46.

Solving the equation, the angles are approximately 22.0 degrees and 68.0 degrees.

Find the value of x if C is the midpoint of AB, AC=4x+5, and AB=78

Answers

Do 78=4x+5 and then subtract 5 from 5 and 5 from 78 and use that that answer and divide it by 4 and that equals x

I hope this helps

Final answer:

Given that AC = 4x+5, and C is the midpoint of AB, meaning AC = CB, then AB = 2*(4x+5). Given that AB = 78, we can solve the equation 8x + 10 = 78 to find x = 8.5.

Explanation:

The subject matter of this question is geometry, specifically concerning line segments and midpoints. If C is the midpoint of AB, then segments AC and CB are equal. This is a fundamental characteristic of midpoints.

Since AC = 4x + 5 and CB = AC, it also means that CB = 4x + 5. This implies that the total length of AB (which is the sum of AC and CB) equals 2 * (4x + 5). Therefore, AB equals 8x + 10.

We are given that AB = 78. So, we can set up and solve the equation 8x + 10 = 78. Subtracting 10 from both sides of the equation gives us 8x = 68. Dividing each side by 8 gives us x = 8.5. Therefore, the value of x that satisfies the given conditions is 8.5.

[tex]\displaystyle{ \frac{3x}{x}+\frac{4}{x}- \frac{x+2}{x} \geq 0 [/tex].

Draw the graph of a rational function that is increasing for x<-4 and decreasing for x>-4 on the coordinate plane below

Answers

For a function to be increasing, as x goes up (to the right) the y value must go up at the same time (meaning that as the function goes to the right, the line goes up). Conversely, when a function is decreasing, as x goes up the y value must go down (as the line goes to the right, the line goes down). We can draw a line at x=-4 (one to the right of -5) and to the left of it, we can draw a line going up as x goes to the right and to the right of x=-4 we can draw a line going down. If you'd like a real example, take |1/(x+4)|. This works due to that since we know that 1/x decreases when x<0 (and is negative) and decreases when x>0, we can get the absolute value of it to make the side left of x=0 flip-flop to make it go up instead of down. In addition, the (x+4) makes the turning point at x=-4 due to that if we plug in x=-4, x+4=0

so the graph will just touch the x axis at x = 1

Answer:

The graph has:

One zero with multiplicity 2.

Step-by-step explanation:

We are given a quadratic function in terms of the variable x as:

[tex]y=2x^2-4x+2[/tex]

The number of zeros of this function is equal to the number of points where the graph of this quadratic function intersects the x axis and the corresponding value of x is the root of this quadratic equation.

Hence, after plotting the graph of this quadratic function we observe that the graph meets the x-axis at just one point.

Hence, the number of zeros of the graph is:
