dominic is buying candy by the pound for a party. for every 10 pounds of candy he buys, he pay $12. What is the cost of the candy, per pound, for the candy?

Answer: 1/3 must be divided into fourths

Step-by-step explanation:

Answer:

[tex]\frac{-1.1x^{25} }{-1.1x^{11} }[/tex]     [tex]\frac{mx^{67} }{mx^{37} }[/tex]

Step-by-step explanation:

Sine (-1.1) is the same as (-1.1) you just put them together and if the numbers are by each other you just add up the exponents. But if the question says this [tex]\frac{-1.1x^{2} }{-1.1x^{3} }[/tex] than you subtract the exponents.

·[tex](-1.1)x^{13}X (-1.1)x^{12} = add\\\frac{-1.1x^{2} }{-1.1x^{2} } = subtract[/tex]

Hope this helps. Have a blessed day :)

Answer:

-√5/2

Explanation: I took the quiz.

Answer:

Option A

Step-by-step explanation:

It's given that cosθ = [tex]-\frac{2\sqrt{5} }{5}[/tex]

Since, cosθ = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex] = [tex]-\frac{2\sqrt{5} }{5}[/tex]

                                        = [tex]\frac{2}{\sqrt{5}}[/tex]

By applying Pythagoras theorem in the right triangle,

(Hypotenuse)² = (Opposite side)² + (Adjacent side)²

(√5)² = (Opposite side)² + (2)²

5 = (Opposite side)² + 4  

Opposite side = √(5 - 4)

                       = 1

Since, sinθ = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]

                  = [tex]\frac{1}{\sqrt{5}}[/tex]

Since, sine is positive in IInd quadrant,

sinθ = [tex]\frac{1}{\sqrt{5}}[/tex]

Therefore, option A will be the answer.

Step-by-step explanation:

Arc Length of CD: 1/8 (36π)= 36/8π = 9/2 π cm.

Answer:

3

Step-by-step explanation:

1 hour = 60 minutes.

1/4 of an hour = 60 minutes / 4 = 15 minutes.

15 minutes / 5 minutes segments = 3

There are 3 five-minute segments in 1/4 of an hour

Answer:

C.

Step-by-step explanation:

Answer is C. because there are a total of 60 minutes in 1 hour. We know that there is 30 minutes in half a hour. Half of 30 minutes is 15 minutes and it takes 3 five minute segments to get 15 minutes.

You can do it like this 60 * 1/4 = 60/4

60/4 = 15/1

15 = 5 * 3

hello your question is incomplete, the missing part of the question is attached below

answer :

1) β1 = 0.25

  β2 = 4.85

2)  40.55 + 0.25 ( math score ) + 4.85 ( hours )

Step-by-step explanation:

1) The estimate for β1 and β2

From the attached excel result the estimates are ;

β1 = 0.25 : This shows the change in the mean value of the  final score in relation to the change in math score while the time is kept constant

β2 = 4.85 : This represents the change in the mean value of the final score in relation to the change in time while the math score is held constant

2) sample regression equation

The Final sample regression equation = 40.55 + 0.25 ( math score ) + 4.85 ( hours )

Step-by-step explanation:

  This is a ratio problem

  Vol cone = 1/3 π r² h

Cone S is 768pi cm3

Cone T is 6144pi cm3

Cone S and cone T are similar I think this means they have the same radius

      Vol cone S  =  1/3 π r² hs    Vol cone T  =  1/3 π r² ht

     Vol  Cone S /  Vol Cone T    =    1/3 π r² hs / 1/3 π r² ht

    Vol  Cone S /  Vol Cone T    =     hs /  ht                                  

               768 / 6144   =  hs / 24       (note the π cancelled out

               h cone s = 768(24) / 6144

               h cone s =   3 cm

The minimum z-score that a data point could have to remain in the top 30% of the data is 0.52.

We have,

To find the minimum z-score that a data point could have to remain in the top 30% of a set of data, we need to find the z-score that corresponds to a cumulative probability of 0.70 (since the top 30% is equivalent to the cumulative probability of 0.70).

Using a standard normal distribution table or a statistical calculator, we can find that a cumulative probability of 0.70 corresponds to a z-score of approximately 0.52 (rounded to two decimal places).

Therefore,

The minimum z-score that a data point could have to remain in the top 30% of the data is 0.52.

Step-by-step explanation:

you said in the comment we need to find the gallons so if we have the cost  10$ per 2 gallons then 20$ per 4 gallons. Then technicly 1 gallon will be 0 $

But if we need to find the value of the red dots it's starting from the top

40$ for the value of 8

30$ for the value for 6

20 $ for the value of 4

10$ for the value of 2

Answer:

Triangle 2

Step-by-step explanation:

5, 12, 13

Use the Pythagorean Theorem

a^2 + b^2 = c^2

a = 5

b = 12

c = 13

25 + 144 = 169

a and b are side lengths

c is the hypotenuse

The theorem states that the square of the side lengths of a right triangle added together equals the square of the hypotenuse

Answer:

B is the right triangle because the sum of the square of each of the two shortest sides will equal the square of the longest side.

Step-by-step explanation:

Pythagorean Theorem says if a triangle is a right triangle with side lengths a, b, and c, then a^2 + b^2 = c^2 where c is the length of the longest side.

So, A. 16^2= 7^2 + 12^2  256 does not = 193 NOT a right triangle

      B. 13^2= 5^2 + 12^2  169 = 169 Yes this is a right triangle

      C. 9^2= 4^2 + 5^2  81 does not = 41 NOT a right triangle

      D. 19^2= 8^2 + 15^2  361 does not = 289 NOT a right triangle

Answer:

0.0668 = 6.68% probability that the average price change of this sample is less than 1.0.

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

Central Limit Theorem

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

Mean µ = 1.1 and variance σ2 = 0.16. You collect a sample of 36 such price changes.

So the standard deviation is:

[tex]\sigma = \sqrt{\sigma^2} = \sqrt{0.16} = 0.4[/tex]

Sample of 36:

This means that [tex]s = \frac{0.4}{\sqrt{36}} = 0.0667[/tex]

Probability that the average price change of this sample is less than 1.0.

This is the pvalue of Z when X = 1. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{1 - 1.1}{0.0667}[/tex]

[tex]Z = -1.5[/tex]

[tex]Z = -1.5[/tex] has a pvalue of 0.0668

0.0668 = 6.68% probability that the average price change of this sample is less than 1.0.
