On solving the provided question, we can say that the spherical balloon's initial radius is 7 cm.; the final radius is 14 cm. ratio =  (7/14) ^2 = 1:4

The length of a circle or sphere, in more contemporary use, is the same as its radius in classical geometry, which is one of the line segments from its center to its circumference. The Latin word radius, which also refers to the spokes of a wagon wheel, gave rise to the term. The distance a circle's center is from any point on its perimeter is its radius. Usually, "R" or "r" is used to indicate it. A radius is a line segment that has one endpoint in the center and one on the circumference of a circle. Circular diameter equals radius The diameter of a circle is the segment that traverses its center and has ends that are on the circle.

The spherical balloon's initial radius is 7 cm.

The final radius is 14 cm.

Answer:

A. 6.25x + 30 > 9.75x+12

Step-by-step explanation:

This is because we know from the problem that x is the minimum number of t-shirts. We also know Company D charges a 6.25 fee for each tee, while Company E charges a 9.75 fee per tee.  Based on the information we know, we can choose the problem.

The decision regarding H0 is to reject it, and we can conclude that there are more defects produced on the day shift.

To determine whether there are more defects produced on the day shift, we can conduct a one-tailed paired t-test based on the given null and alternative hypotheses:

H0: μd ≤ 0 (There are fewer or equal defects on the day shift)

H1: μd > 0 (There are more defects on the day shift)

Where μd represents the population mean difference between the day shift and afternoon shift.

We have the following sample information:

Day 1 2 3 4

Day shift 10 12 15 18

Afternoon shift 8 9 13 17

To perform the test, we need to calculate the differences between the day shift and afternoon shift for each day:

d = (Day shift) - (Afternoon shift)

d = 10-8, 12-9, 15-13, 18-17

d = 2, 3, 2, 1

Now, let's calculate the mean and standard deviation of the differences:

Mean (xbar d) = (2 + 3 + 2 + 1) / 4 = 2.00

Standard Deviation (s) = √[(∑(d - x bar d)^2) / (n-1)]

= √[\(( (2-2)^2 + (3-2)^2 + (2-2)^2 + (1-2)^2) / (4-1)\)]

= √[(0 + 1 + 0 + 1) / 3]

= √(2/3)

≈ 0.816

Next, we can calculate the test statistic t using the formula:

t = (x bar d - μd) / (s / √n)

For our case:

x bard = 2.00

μd (from the null hypothesis) = 0

s ≈ 0.816

n = 4

t = (2.00 - 0) / (0.816 / √4)

 = 2.00 / (0.816 / 2)

 ≈ 4.90 (rounded to 3 decimal places)

To determine the p-value, we need to find the area under the t-distribution curve to the right of the test statistic (t = 4.90) with (n-1) degrees of freedom.

Using a t-table or statistical software, we find that the p-value is between 0.001 and 0.005.

Since the p-value (between 0.001 and 0.005) is less than the significance level of 0.050, we reject the null hypothesis (H0).

The decision rule is as follows: If the p-value is less than the significance level, we reject H0; otherwise, we do not reject H0.

Therefore, the decision regarding H0 is to reject it, and we can conclude that there are more defects produced on the day shift.

Step-by-step explanation:

When there is a negative exponent like x^-2 it equals 1/(x^2) the negative puts the number as a fraction so continuing...

-12(x^-2) (y^-2) can be rewritten as

-12 (1/x^2) (1/y^2) now we plug in x = -2 and y = 4

Answer: 32 matches

Step-by-step explanation:

Let the games in total that the baseball team played be represented by x.

Based on the information given in the question, we can form an equation as:

62.5% × x = 20

62.5/100 × x = 20

0.625 × x = 20

0.625x = 20

x = 20/0.625

x = 32

The team played a total of 32 matches.

The count of letter f (any case) in ' if fred is from a part of france, then of course fred's french is good', is 8.

A word, phrase, or sentence in which no letter of the alphabet appears more than once is known as a heterogram (from the prefix hetero-, meaning "different," and the suffix -gram, meaning "written"). The same idea has also been denoted by the phrases isogram and nonpattern word.

Language on Vacation: An Olio of Orthographical Oddities, written by Dmitri Borgmann in 1965, mentions the idea, however he refers to it as an isogram. Borgmann asserts that he "introduced" the term "isogram" in a 1985 essay.

(−1,0)∪(0,1).

The function in this problem is defined as follows:

h(x) = 5x³ - 3x^5.

To obtain the intervals for increase of decrease, the critical points of the function need to be obtained, which are the values of x for which the derivative is of zero.

The derivative of the function in this problem is given as follows:

h'(x) = 15x² - 15x^4.

Hence the critical points of the function are given as follows:

15x² - 15x^4 = 0

15x²(1 - x²) = 0.

Answer:

A) at (5, 4.5) diving the cost by the number of songs purchased gets you $0.9 per song which is your constant

B) y = x(.9) ; x= number of songs purchased & y= total cost

C) using the equation to find the cost of buying each separatly

60 (.9) = $54

$54 is less than $58, So Susan should buy the songs seperatly.

A) Constant of Proportionality for the given situation is;

Constant of Proportionality = $0.9

B) The equation to represent the relationship in the question is;

y = 0.9x

C) Cost of 60 songs individually = $54. Thus, Susan is advised to pay individually and not with flat fee.

A) To get the constant of proportionality, let us pick a point coordinate on the graph. Let's pick (20, 18). This means;

Number of songs purchased = 20

Total Cost of 20 songs = $18

Constant of proportionality would be the cost per song; k = 18/20 =

$0.9 per song

B) Since the y-axis represents Total Cost and the x-axis represents number of songs purchased, then we can develop the relationship;

y = kx

where k is constant of proportionality which we have seen to be $0.9.

Thus, the equation to represent the relationship is;

y = 0.9x

C) Using the equation above, since she downloads 60 songs a month, then the total cost for this would be;

Total cost = 60 x 0.9

Total cost = $54

This cost of $54 is less than flat fee of $58 offered by another company. Thus, i would advice Susan to pay for each song separately instead of the flat fee.

x = 6

Step-by-step explanation:

Line segment SU is a bisector of angle <TSV which means it divided the angle into two equal parts:

The measure of <TSV = 62 in this case the measure of <VSU = 62/2 = 31

we can write the following equation to find the value of x

5x + 1 = 31 subtract 1 from both sides

5x = 30 divide both sides by 5

x = 6

The X value corresponding to z = -2.00 is 60. The X value corresponding to z = -2.00 is 60. This means that the observation with a z-score of -2.00 is 60 units below the population mean of 80.

To find the X value corresponding to z = -2.00, we can use the formula:
z = (X - µ) / σ
Substituting the given values, we get:
-2.00 = (X - 80) / 10
Solving for X, we get:
X = (-2.00 x 10) + 80
X = 60

The z-score measures the number of standard deviations an observation is from the mean. In this case, the given z-score of -2.00 indicates that the observation is 2 standard deviations below the mean.
To find the corresponding X value, we use the formula:
z = (X - µ) / σ
Where z is the standard normal distribution value, X is the corresponding raw score, µ is the mean of the population, and σ is the standard deviation of the population.
Substituting the given values, we get:
-2.00 = (X - 80) / 10
Solving for X, we get:
X = (-2.00 x 10) + 80
X = 60

Step-by-step explanation:

The average hourly change in tub fullness is ₋1/13.

Jenna she starts her shift, the tub of chocolate ice cream is 2/3 full.

After she finishes her shift 6 1/2 hours , there is only 1/6 of tub left.

the average hourly change in tub fullness = ?

subtract the initial quantity from the quantity left after 6 1/2 hours.

⇒ 2/3 ₋ 1/6

= 1/2

Divide the quantity by 6 1/2 hours.

time is represented in improper fraction, convert it into proper fraction.

6 1/2  = 12 ₊ 1/2

= 13/2

⇒ 1/2 ÷ 13/2

= 1/13
