a 3 pound bag of apples cost $6. if ther is approximately 8 apples in a pound how much would one apple cost?

The probability of the sixth child being born as a boy is 0.5 or 50%. It is irrespective to the five boys born previously.

Since probability of a girl or boy being born is 50%,

Probability of Girl being born, P(G) = ½

Probability of boy being born, P(B) = ½

When one is calculating the probability of any one of the two events occurring or both evens have a chance of occurring, considering the events are non-mutually exclusive, the rule of addition is used.

Rule of addition: P(A or B)= P(A) + P(B) –P(A+B)

Where P(A)- probability that event A takes place

P(B)- Probability that event B takes place

P(A+B)-  probability of both events taking place.

In this case, both events cannot take place simultaneously, i.e., they are mutually exclusive, hence,

P(G or B)= ½ + ½ = 2/4 = ½ = 0.5.

Therefore, Probability of boy being born is 0.5

The distribution appears to be approximately bell-shaped and symmetric. The majority of the data falls between 40 and 80 units of hand grip strength, with the highest frequency occurring around 60 units.

The data appears to be unimodal, with a single clear peak in the middle. The distribution does not appear to be skewed to the left or right.

Overall, the distribution appears to be relatively normal, with the majority of the data falling within one or two standard deviations of the mean. This suggests that the data is relatively normally distributed and that the mean and standard deviation would be appropriate measures of central tendency and variability, respectively.

Overall, the histogram suggests that the data is relatively normally distributed. This means that the mean and standard deviation would be appropriate measures of central tendency and variability, respectively. Additionally, because the distribution appears to be relatively symmetrical, the median would also be a reasonable measure of central tendency.

The value of z that corresponds to 68% of the observations falling below is 0.84, and the value of z that corresponds to 75% of the observations falling above is 1.15.

A. To find the value of z that corresponds to 68% of the observations falling below, we can use the z-score formula. The z-score formula is z = (x-μ)/σ, where x is the value we are looking for, μ is the mean of the normal distribution, and σ is the standard deviation. Using this formula and a standard normal table, we can find that the value of z is 0.84. This means that 68% of the observations fall below z = 0.84. We can sketch a standard normal curve with this value of z marked on the axis by drawing a bell-shaped curve with the value of 0.84 marked on the x-axis.

B. To find the value of z that corresponds to 75% of the observations falling above, we can use the same formula and a standard normal table. We can find that the value of z is 1.15. This means that 75% of the observations fall above z = 1.15. We can sketch a standard normal curve with this value of z marked on the axis by drawing a bell-shaped curve with the value of 1.15 marked on the x-axis.

The system of equations are solved and the number of regular and premium cards are 9 and 16 respectively

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , let the regular cards be x

And , the premium cards be y

The cost of one regular card x = $ 0.40

The cost of one premium card y = $ 0.65

The total cost = $ 14

The total number of cards = 25

Substituting the values in the equation , we get

x + y = 25   be equation (1)

0.40x + 0.65y = 14   be equation (2)

Multiply by 100 on both sides of equation (2) , we get

40x + 65y = 1400

Divide by 5 on both sides of the equation , we get

8x + 13y = 280   be equation (3)

Multiply equation (1) by 8 , we get

8x + 8y = 200   be equation (4)

Subtracting equation (4) from equation (3) , we get

13y - 8y = 280 - 200

5y = 80

Divide by 5 on both sides of the equation , we get

y = 16

So , the number of premium cards is 18

Substitute the value of y in equation (1) , we get

Answer:A linear model is appropriate because the scatterplot shows a strong, positive linear relationship.

Step-by-step explanation:

The new length of the living room floor would be 14.4 meters and the new width would be 6 meters.

1. Original Length = 12 meters  

2. Original Width = 5 meters

3. Increase by 20%

4. New Length = 12 + (20% of 12) = 12 + 2.4 = 14.4 meters

5. New Width = 5 + (20% of 5) = 5 + 1 = 6 meters

The original length of the living room floor was 12 meters and the original width was 5 meters. The owner decided to increase the living room dimensions by 20%, so the new length of the living room floor is 14.4 meters and the new width is 6 meters. This is calculated by adding 20% of the original length and width to the original values. For the length, this is 12 + (20% of 12) which is 12 + 2.4 = 14.4 meters. For the width, this is 5 + (20% of 5) which is 5 + 1 = 6 meters. The increase of 20% in the dimensions of the living room floor makes it look more spacious and inviting.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

10 dimes = $1

1 dime = $0.1

4 quarters = $1

1 quarter = $0.25

Now,

Number of dimes = x

Number of quarters = (5/6)x

Now,

Duretta has collected $7.40 in all.

This means,

0.1x + 0.25(5/6)x = 7.40

0.1x + 0.21x = 7.40

0.31x = 7.40

x = 7.40/0.31

x = 23.87

x = 24

And,

(5/6)x

= 5/6 x 24

= 20

We can cross-check.

24 x 0.1 + 20 x 0.25 = 7.40

2.4 + 5 = 7.40

7.40 = 7.40

Thus,
