Total number of marbles = 10

Number of red marbles = 4

Number of blue marbles = 6

Probability = [tex]\frac{number of favorable outcomes}{total number of outcomes}[/tex]

The probability that the first marble is blue = [tex]\frac{6}{10}[/tex]

The probability that the first marble is red = [tex]\frac{4}{9}[/tex] ; 9 because 1 marble has already been taken out.

Joint probability= probability of event A * Probability of event B

The 3 inside angles of a triangle need to equal 180 degrees.

You are given 28 for one.

The second on is adding 58 + 77 = 135 degrees.

X = 180 - 28 - 135 = 17 degrees

y = 4eˣ has a vertical stretch by a factor of 4 compared to the parent graph so the range is the same as it's parent graph.

Answer:

In order to keep up with rising cost carpenter needs to increase his $30.00 per hour rate to 35.40 $.

Explanation:

 To keep up with rising cost a carpenter needs to increase his $30.00 per hour rate by 18%.

So hour rate of carpenter = 30.00 $

Rate of increase = 18 % = 0.18

New hour rate = Initial hour rate + Rate of increase x Initial hour rate

                         = 30 + 0.18 x 30 = 30 + 5.4 = 35.40 $

So in order to keep up with rising cost carpenter needs to increase his $30.00 per hour rate to 35.40 $.

The carpenter's new hourly rate after an 18% increase on his current rate of $30.00 will be $35.40 per hour.

To calculate the new hourly rate with an 18% increase, first find 18% of the carpenter's current $30.00 per hour rate. The formula for calculating the percentage increase is:

Percentage increase in wage = (Current hourly rate) x (Percentage increase) / 100

In this case, the calculation would be: $30.00 x 18% / 100 = $5.40.

Next, add this increase to the current rate to find the new rate:

New hourly rate = Current hourly rate + Increase in wage

Applying the values:

New hourly rate = $30.00 + $5.40 = $35.40 per hour.

So, the carpenter needs to charge $35.40 per hour to achieve an 18% increase in his rate.

Final answer:

The price per pound of turkey is $7.98.

Explanation:

To find the price per pound, divide the total cost by the weight. In this case, Bryan paid $19.95 for 2.5 pounds of turkey. So, the price per pound is $19.95 divided by 2.5, which is $7.98 per pound.To calculate the price per pound of turkey that Bryan paid, we divide the total cost by the total weight. Bryan paid $19.95 for 2.5 pounds of turkey.

Divide the total cost by the total weight in pounds.

$19.95 ÷ 2.5 pounds = $7.98 per pound

Thus, the price per pound of turkey that Bryan paid is $7.98.

_____

= 1/9

Answer:

The answer is D . The means are equal and the standard deviation of Plot 1 is larger than the standard deviation of Plot 2.  

Step-by-step explanation:

The histogram gives you information about the number of times a specific number appears on your sample. Then you can construct your sample looking at each histogram. For example in Plot 1 the value -2 appears two times. If you this,  you obtain the following samples:  

Plot 1: -2, -2, -1, -1, 0, 0, 1, 1, 2, 2

Plot 2: -2, -1, -1, 0, 0, 0, 0, 1, 1, 2

If you calculate the means by adding and dividing by the number of obs you find equal means  (0) because the data is centered around 0. ( no deviations to left or right).  

Now the   standard deviation (sd) can be infered in the histogram. The sd measures the distance around the mean of the data. When data is concentrated very close to the mean, the sd is lower as in Plot 2 (More points are 0 or around zero in Plot 2). In plot 1 your points are farther apart from the mean of zero so the sd is higher.  

ANSWER

[tex]P(1<X<5)=0.51[/tex]

EXPLANATION.

The probability of selecting a number between 1 and 5 can be calculated by summing all probabilities between 1 and 5

[tex]P(1<X<5)=P(X=2)+P(X=3)+P(X=4)[/tex]

[tex]P(1<X<5)=0.07+0.22+0.22[/tex]

You originally had 30 canicas in your collection.

Let's denote the total number of canicas in your collection as C

According to the information provided:

1. Tales received 1/5 of the total:

  Tales received [tex]\( \frac{1}{5} \)[/tex] of C, which can be expressed as [tex]\( \frac{1}{5} \times C \).[/tex]

2. You received 1/3 of the rest:

  After giving Tales his share, there are [tex]\( \frac{4}{5} \)[/tex] of the canicas left. You received [tex]\( \frac{1}{3} \)[/tex] of this remaining amount. So, your share is [tex]\( \frac{1}{3} \times \frac{4}{5} \times C \)[/tex].

3. Pitagórica received the remaining 16 canicas:

  After Tales and you received your shares, Pitagórica received the remaining canicas, which is given as 16 canicas.

Now, we can set up an equation to represent this situation:

[tex]\[ \frac{1}{5} \times C + \frac{1}{3} \times \frac{4}{5} \times C + 16 = C \][/tex]

Now, let's solve for C:

[tex]\[ \frac{1}{5}C + \frac{4}{15}C + 16 = C \][/tex]

Combine the terms with C:

[tex]\[ \frac{3}{15}C + \frac{4}{15}C + 16 = C \][/tex]

Combine the terms on the left side:

[tex]\[ \frac{7}{15}C + 16 = C \][/tex]

Subtract [tex]\( \frac{7}{15}C \)[/tex] from both sides:

[tex]\[ 16 = \frac{8}{15}C \][/tex]

Now, solve for C:

[tex]\[ C = \frac{15}{8} \times 16 \][/tex]

[tex]\[ C = 30 \][/tex]

Therefore, you originally had 30 canicas in your collection.

Complete question:

He divided my collection of dogs among my three best friends. A Tales to him he gave 1/5 of the total, a Here to me 1/3 of the rest, and lastly to Pitagórica, he gave me the 16 canicles that I sobraron.

How many canicas do I have in my collection?

Answer:

148.8

Step-by-step explanation:

The original price of the necklace before the 20% increase was approximately £155 (£186 / 1.20).

To find the original price of the necklace before the 20% increase, we can use the formula:

Original Price = Final Price / (1 + Percent Increase)

Given that the final price is £186 and the increase is 20%, we substitute these values into the formula:

Original Price = £186 / (1 + 0.20)

Calculating inside the parentheses first:

1 + 0.20 = 1.20

Now, divide the final price by 1.20:

Original Price = £186 / 1.20 ≈ £155

So, the original price of the necklace before the increase was approximately £155.

The statement "a cone is a polyhedron" is false. The correction option is B.)False

A polyhedron is a three-dimensional shape with flat polygonal faces, straight edges and sharp corners or vertices.

Whereas, a cone is a three-dimensional geometric figure that has a flat surface and a curved surface, and is pointed towards the top.

From the above definitions, we can infer that a cone is not a polyhedron.

Hence, the statement "a cone is a polyhedron" is false. The correction option is B.)False

the question in English

Mateo will reproduce a photo measuring 5 cm per side on a scale of 3/4

How much will the square side of the copy measure?

Will the size of the copy be larger or smaller than the original?

we know that

the scale factor is equal to [tex]\frac{3}{4}[/tex]

Let

x----------> the original length side

y--------> the copy length side

[tex]y=\frac{3}{4}*x[/tex]

we have that

[tex]x=5\ cm[/tex]

substitute the values

[tex]y=\frac{3}{4}*5=3.75\ cm[/tex]

therefore

the answer Part a) is

the length side of the copy measure is [tex]3.75\ cm[/tex]

Part b)

we know that

the size of the original photo is------> [tex]5*5=25\ cm^{2}[/tex]

the size of the copy is------> [tex]3.75*3.75=14.06\ cm^{2}[/tex]

so

[tex]14.06\ cm^{2} < 25\ cm^{2}[/tex]

Answer:

- The error is: [tex](\frac{31}{4})(\frac{1}{3})[/tex]

- The correct solution is:  [tex]\frac{93}{4}=23^{\frac{1}{4}}[/tex] (Carla can make approximately 23 recipes with the clay).

Step-by-step explanation:

1. Carla must divide [tex]\frac{31}{4}[/tex] ÷ [tex]\frac{1}{3}[/tex] as following:

- Take the reciprocal of [tex]\frac{1}{3}[/tex].

- Multiply the numerators and the denominators.

Then:

[tex](\frac{31}{4})(\frac{1}{3})=\frac{(31)(3)}{(4)(1)}=\frac{93}{4}[/tex]

2. As a mixed number:

[tex]\frac{93}{4}=23^{\frac{1}{4}}[/tex]

3. Therefore, Carla can make approximately 23 recipes with the clay.

Carla can make 23 full modeling clay recipes with 7 3/4 cups of salt, with a quarter cup of salt remaining.

To find out how many recipes of modeling clay Carla can make with 7 3/4 cups of salt, we need to divide the total amount of salt she has by the amount required for one recipe. Since one recipe requires 1/3 cup of salt, we will perform the following division: 7 3/4 divided by 1/3.

To simplify this, first, convert 7 3/4 to an improper fraction, which is (7 × 4 + 3)/4, or 31/4. Now, dividing by a fraction is the same as multiplying by its reciprocal. Therefore, we multiply 31/4 by the reciprocal of 1/3, which is 3/1.

31/4 × 3/1 = 93/4, which simplifies to 23 1/4.

This means Carla can make 23 full recipes with a little salt left over.
