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.

It would be 6 km because 4 1/2 divided by 3 = 1.5x4=6

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

Let us say original price of the laptop was x dollars.

Price paid by Tom for the laptop = $245.97

Now this price paid by tom was 3/5 of the original price.

So we can make an equation using this information as :

[tex]\frac{3}{5}x=245.97[/tex]

So here 3/5 is in multiplication on the left, so dividing it on the right side we have:

x=409.95

So the original price of the laptop was $409.95

Answer: The original price of the laptop was 409.95 dollars.

Answer:

$409.95

[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]

Final answer:

The sampling distribution of the sample mean will be approximately normally distributed with a mean of 64 and a standard error calculated by dividing the population standard deviation (25) by the square root of the sample size (155).

Explanation:

The student's question involves the concept of the sampling distribution of the sample mean. Given a population with a mean (μ) of 64 and a standard deviation (σ) of 25, and drawing samples of size 155, the sampling distribution of the sample mean will have a mean equal to the population mean, which is 64. The standard deviation of the sampling distribution (σx), known as the standard error, will be the population standard deviation (σ) divided by the square root of the sample size (n), thus σx = 25/ √155. As the sample size is large, according to the central limit theorem, this sampling distribution will be approximately normal.

Therefore, the sampling distribution of the sample mean will be approximately normally distributed with a mean (μx) of 64 and a standard error (σx) which can be calculated as mentioned above.

5y    +     6      −(10y    +    3)

Distribute the Negative Sign:

=        5y     +     6    +    −1(10y     +    3)

=        5y     +     6    +    −1(10y)     +     (−1)(3)

=        5y     +    6    +    −10y     +      −3

Combine Like Terms:

Answer:

Distance from chin to forehead is 1.5 times the distance between ears.

Step-by-step explanation:

We are told that distance from chin to forehead for the average person is 9 inches and distance between a person's ears is 6 inches. We are supposed to compare the ratio of a person's chin to forehead distance with respect to the distance between his ears.

We can present our given information as: [tex]\frac{9}{6}[/tex]

[tex]\frac{9}{6} =1.5[/tex]

Therefore, distance from chin to forehead is 1.5 times the distance between ears.

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]

therefore

the answer part b) is

The size of the copy be smaller than the original

The given formula is A= bh/2

First multiply both sides by 2:

2A = bh

Now divide both sides by b:

h = 2A/b

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.

Step-by-step explanation:

[tex]\text{ Total inches of snow town got in a week }=5\frac{1}{3}=\frac{16}{3}[/tex]

[tex]\text{ Amount of snow it is receiving on Monday}=2\frac{3}{4}=\frac{11}{4}\text{ inches }[/tex]

[tex]\text{Amount it is receiving in remaining week is given by}[/tex]

[tex]\frac{16}{3}-(\frac{11}{4}+\frac{3}{2}+\frac{7}{8})\\\\=\frac{16}{3}-\frac{22+12+7}{8}\\\\=\frac{16}{3}-\frac{41}{8}\\\\=\frac{128-125}{8}\\\\=\frac{5}{24}\text{ inches }[/tex]

So, the amount of snow the town get the rest of the week is given by

[tex]\frac{5}{24}\text{ inches }[/tex]

(1) .20 (2) .40 (3) .12 (4) Less than

Step-by-step explanation:

You have to look at the table.  There are 5 columns with 10 rows.  5x10=50

Then simply count the boxes that have the correct number of currency for instance, if they are asking for EXACTLY 1 dime then you rule out the ones that have 2 or 3 dimes and only the count the ones that have a single dime.   So you count PDN but you would not count PDD.  There are 20 boxes that have a single dime in them.  20 out of the 50 boxes. 20/50=.40 (answer 2)

The estimated probability that exactly two of the three coins Avery randomly picked are nickels is . 20

The estimated probability that exactly one of the three coins Avery randomly picked is a dime is . 40

The estimated probability that all three coins Avery randomly picked are pennies is . 12

The answer to #1 is .20 or 20% and the answer to #2 is .40 or 40%.  20% is less than 40% so...

The estimated probability that exactly two of the three coins Avery randomly picked are nickels is  LESS THAN the estimated probability that exactly one of the three coins Avery randomly picked is a dime.

Answer:

The answer to #1 is .20 or 20% and the answer to #2 is .40 or 40%.  20% is less than 40% so...
