Answer:

Another way to calculate the correlation coefficient (r) is to multiply the slope of the regression line by the standard deviation of X and then divide by the standard deviation of Y.

The values of the missing angles and sides after dilation are:

m∠C'B'D' = 95°,  CQ = 6 and  B'D' = 11.

m∠C'B'D = 180° - m∠B'C'D' - m∠B'D'C'

m∠B'C'D = m∠BCD, m∠B'D'C' = m∠BDC  (dilation)

m∠C'B'D = 180° - 34° - 51° = 95°

Thus, by way of scale factor we can say that:

BC/B'C' = BD/B'D' = 36/18 = 2

B'D' = ¹/₂BD = ¹/₂ * 22 = 11

ΔC'P'Q ∼ ΔCPQ

Thus:

C'Q'/CQ = C'D'/CD = D'Q'/DQ

CQ = 2C'Q' = 2 * 3 = 6

Therefore, m∠C'B'D' = 95°,  CQ = 6 and  B'D' = 11.

Step-by-step explanation:

Because the people were randomly assigned to one of the two groups, there is a randomness to both groups making them the same. The group that doesn't get the cream is a control group so any differences observed between the control and the group being tested would be due to the cream.

Answer:

B. The variability between each subject would be evenly distributed between the two groups, so any observed differences in the level of irritation between the two groups are more likely due to the new cream.

The inequality that correctly describes the number of ounces of water, w, that tom drinks each day is d. 64<w.

Amount of water that the bottle can hold = 32 ounces

Bottles of water consumed = 2

A mathematical comparison and representation of the connection between two expressions is known as an inequality. It can be regarded as a generalisation of an equation and is denoted by signs such as <, > and =.

Tom consumes more than two complete bottles of water every day. Since each bottle can carry up to 32 ounces of water, we can describe Tom's daily water consumption as -

= w > 2 × 32

Therefore,

Simplifying the right side of the inequality:

w > 64

Complete Question:

Answer:

Since pitch is such a close proxy for frequency, it is almost entirely determined by how quickly the sound wave is making the air vibrate and has almost nothing to do with the intensity, or amplitude, of the wave. That is, "high" pitch means very rapid oscillation, and "low" pitch corresponds to slower oscillation.

Denia's score will be \(+5\).

Steve's score is 5 points away from zero.

This means it may be \(+5\) or \(-5\)

Denia's score is opposite of Steve's.

This means Steve's score is opposite of Denia's.

Denia's score is positive.

3/4y+6=0

Step 1: Subtract 6 from both sides :

3/4y + 6 - 6 = 0 - 6

3/4y = -6

Answer:

The estimated probability that Ginger will eat a a pizza everyday of the week is;

D. 8/10 = 80%

Step-by-step explanation:

The given parameters are;

The frequency with which Ginger buys launch = Everyday

The percentage of the time the cafeteria has pizza out = 80%

The outcome of 0 and 1 = No pizza available

The outcome of 2, 3, 4, 5, 6, 7, 8, and 9 = Pizza available

Therefore, we have the;

Group number  \({}\)                          Percentage of time pizza available

1                     \({}\)                          80%

2                     \({}\)                          80%

10                     \({}\)                          80%

Therefore, the sum of the percentages outcome the days Ginger eats pizza = 0.8 + 0.8 + 0.8 + 0.8 + 0.4 + 1 + 0.8 + 1 + 0.8 + 0.8 = 8

The number of runs of simulation = 10 runs

The estimated probability that Ginger will eat a a pizza everyday of the week = (The sum of the percentages outcome the days Ginger eats pizza)/(The number of runs of simulation)

∴ The estimated probability that Ginger will eat a a pizza everyday of the week = 8/10

The distance between points (1,3) and (9,18) is 17.

Step-by-step explanation:

Here's the required formula to find distance between points (1,3) and (9,18) :

\(\star{\small{\underline{\boxed{\sf{Distance = \sqrt{\Big(x_{2} - x_{1} \Big)^{2} + \Big(y_{2} - y_{1} \Big)^{2}}}}}}}\)

Here, we have provided :

\(\begin{gathered}\begin{gathered} \footnotesize\rm {\underline{\underline{Where}}}\begin{cases}& \sf x_2 = 9\\ & \sf x_1 = 1\\ & \sf y_2 = 18\\& \sf y_1 = 3\end{cases} \end{gathered}\end{gathered}\)

Substituting all the given values in the formula to find the distance between points (1,3) and (9,18) :

\(\implies{\small{\sf{d = \sqrt{\Big(x_{2} - x_{1} \Big)^{2} + \Big(y_{2} - y_{1} \Big)^{2}}}}}\)

\(\implies{\small{\sf{d = \sqrt{\Big(9 - 1\Big)^{2} + \Big(18 - 3\Big)^{2}}}}}\)

\(\implies{\small{\sf{d = \sqrt{\Big( \: 8 \: \Big)^{2} + \Big( \: 15 \: \Big)^{2}}}}}\)

\(\implies{\small{\sf{d = \sqrt{\Big( 8 \times 8\Big) + \Big( 15 \times 15\Big)}}}}\)

\(\implies{\small{\sf{d = \sqrt{\big( \: 64 \: \big) + \big( \: 225 \: \big)}}}}\)

\(\implies{\small{\sf{d = \sqrt{64 + 225}}}}\)

\(\implies{\small{\sf{d = \sqrt{289}}}}\)

\(\implies{\sf{\underline{\underline{\red{d = 17}}}}}\)

Hence, the distance between points (1,3) and (9,18) is 17.

The number of adults in the museum, using the fractional value of girls and boys, is 75.

A fractional value refers to a portion of the total value.

A fractional value can be depicted in fractions, decimals, or percentages.

A fractional value can also be represented as a ratio or proportion.

In this situation, the fractional number of adults is determined using subtraction.

The total number of people in a museum = 250

The fraction of girls in the museum = 2/5

2/5 of 250 = 100 girls

The fraction of boys in the museum = 3/10

3/10 of 250 = 75

Alternatively:

2/5 + 3/10 = 7/10

7/10 of 250 = 175

Therefore, the number of adults = 75 [250 - (100 + 75)]

A. approximately Normal, with a mean of 1100 and a standard error of 204.12.

This is because the Central Limit Theorem (CLT) states that the sampling distribution of the sample mean tends towards a normal distribution with a mean equal to the population mean and a standard error equal to the population standard deviation divided by the square root of the sample size.

In this case, the sample size is 24, so the standard error is 1000/sqrt(24) = 204.12. Therefore, the sampling distribution of the sample mean is approximately normal with a mean of 1100 and a standard error of 204.12.

The required solution to the given inequality is x > 16, as shown in the graph.

In mathematics, an inequality is a statement that two values or expressions are not equal. An inequality uses one of the comparison symbols: "<" (less than), ">" (greater than), "≤" (less than or equal to), "≥" (greater than or equal to), or "≠" (not equal to). For example, "x + 3 < 10" is an inequality that states that the value of x plus 3 is less than 10.

Here,
As mentioned in the question,
To graph, the solution of the inequality (x+8) > 2 (2.0 + 10).

Simplifying the given inequality:
(x+8) > 2 (2.0 + 10)

x+ 8 > 2(12)
x > 24 - 8
x > 16

Answer:

  q = 2

Step-by-step explanation:

You want to find q such that the difference between the two roots of 3x²-5x+q is 1/3.

In quadratic ax²+bx+c, the sum of the roots is (-b/a). For roots p and s, this tells us ...

  p + s = -(-5)/3 = 5/3

The problem statement tells us the difference is ...

  p - s = 1/3

Adding these two equations gives ...

  2p = (5+1)/3 = 2

  p = 1 . . . . . . . . . . . . . divide by 2

  s = p -1/3 = 2/3 . . . . find the smaller root

The product of the two roots is (c/a) = (q/3):

  ps = (1)(2/3) = q/3

  q = 2 . . . . . multiply by 3

The value of q is 2.

Answer and Explanation:

Volume of a cylinder is given by

V= Pi*r²*h

where v= volume of the cylinder

Pi is constant = 22/7 or 3.14159

r= radius of the circle of the cylinder

h= height of the cylinder

If two cylinders are measured proportionally to the other based on radius and height of each cylinder, we look at the proportional equality of the ratio of the radius and height of one cylinder to the other. If one cylinder for example has ratio of radius and height =2/4 then it is proportional to the other cylinder with ratio 1/2

Answer: One of the cylinders is short and wide, while the other is tall and thin.

Owners equity is defined as the proportion of the total asset value of the company

Owner's equity at the end of the year = (Income for the year - Expenses for the year) + capital invested at the beginning of year.

(A) (a) = (180,000 - 60,000) + 100,000

          = 220,000

(B) (b) = (150,000 - 170,000) + 250,000

          = 230,000

(C) (145,000 - c) + 320,000 = 300,000

145,000 - c = 300,000 - 320,000

145,000 - c = -20,000

c = 145,000 + 20,000

c = 165,000

(D) (d - 200,000) + 700,000 = 840,000

d - 200,000 = 140,000

d = 140,000 + 200,000

d = 340,000

(E) (640,000 - 270,000) + e = 800,000

e = 800,000 - (640,000 - 270,000)
