Answers

Film cameras allow a limited number of shots per role. 36 images can a photographer typically shoot on a roll. Thus, option A is the correct option.

The most cost-effective per shot is the roll, which typically yields 36 exposures. The 35mm format comes in a few different forms. On a roll of 35mm film, half-frame cameras may capture twice as many images at a smaller size.

Rolls of film typically have 24 or 36 exposures. The number of pictures you may take before loading a new roll may be limited as a result. However, some photographers view this as a benefit since it forces them to be more deliberate and exact when creating their images.

The point (2, 5) is a solution to the system of equations: y = x + 2.

Let's test each system of equations:

y = x - 8

2x + y = 7

Substituting x = 2 and y = 5 into the equations:

5 = 2 - 8 (not true)

2(2) + 5 = 7 (not true)

The point (2, 5) is not a solution to this system of equations.

y = x + 2

y = x + 5

y = -1/2 * x + 6

y = 3x - 1

y = 2/3 * x + 6

Substituting x = 2 and y = 5 into the equations:

5 = 2 + 2 (true)

5 = 2 + 5 (not true)

5 = -1/2 * 2 + 6 (not true)

5 = 3 * 2 - 1 (not true)

5 = 2/3 * 2 + 6 (not true)

The point (2, 5) is a solution to the equation y = x + 2.

The estimate obtained from a sample of which of the following sizes would
most likely be closest to the actual parameter value of a population?
K
A. 75
OB. 15
O C. 150
OD. 45

Answers

The sample that would have an estimate that is likely closest to the actual value of the population is C. 150.

Why would this sample be better ?

The size of the sample has a direct impact on the likelihood of obtaining an estimate that closely approximates the actual parameter value of the population.

In this context, a larger sample size, such as the one in option C with a magnitude of 150, is more inclined to yield an estimate that is nearest to the true parameter value. The rationale behind this lies in the fact that a larger sample size mitigates the effects of sampling error, resulting in a more accurate and representative depiction of the entire population. Consequently, the estimate derived from a sample of 150 would be expected to offer a higher level of precision and proximity to the actual parameter value.

What is the radius of a circle of circumference 2,74m​

Answers

Answer:

Step-by-step explanation:

The formula to calculate the circumference of a circle is given by C = 2πr, where C represents the circumference and r represents the radius. Rearranging the formula, we have r = C / (2π).

Substituting the given circumference of 2.74 m into the formula, we get:

r = 2.74 m / (2π) ≈ 0.4367 m

Therefore, the radius of a circle with a circumference of 2.74 m is approximately 0.4367 meters.

Find the component form of AB with initial point A(8, -2) and terminal point B(-2, -2).

Answers

The component form of AB with initial point A(8, -2) and terminal point B(-2, -2) is (-10, 0).

To find the component form of vector AB with initial point A(8, -2) and terminal point B(-2, -2), we need to subtract the coordinates of point A from the coordinates of point B.

Let's calculate the components:

The x-component of AB is obtained by subtracting the x-coordinate of point A from the x-coordinate of point B:

x-component = x-coordinate of B - x-coordinate of A

= -2 - 8

= -10

The y-component of AB is obtained by subtracting the y-coordinate of point A from the y-coordinate of point B:

y-component = y-coordinate of B - y-coordinate of A

= -2 - (-2)

= -2 + 2

= 0

In vector notation, we can represent vector AB as AB = (-10, 0), where the x-component represents the horizontal displacement and the y-component represents the vertical displacement from point A to point B.

Geometrically, the vector AB can be visualized as the directed line segment from point A to point B, with a horizontal displacement of -10 units and no vertical displacement (0 units). The negative sign indicates that the direction of AB is from right to left along the x-axis.

Volume of 90% mixture = y

Percentage of alcohol solution needed = 40%

300(0.3) + y(0.9) = 40%

300(0.3) + 0.9y = 0.4(300)

90 + 0.9y = 120

Collect like terms

0.9y = 120 - 90

The equation representing the number of kilograms of oranges that the store needs to sell is: Remaining kilograms = -7 kg.

To determine the number of kilograms of oranges that the store still needs to sell, we can subtract the amount of oranges already sold from the target amount of oranges.

Let's denote the target amount of oranges as T and the amount of oranges already sold as S.

According to the information given, the store wants to sell 5 kilograms of oranges in one week, so T = 5 kg.

The store has already sold 12 kilograms of oranges, so S = 12 kg.

To find the remaining amount of oranges that the store needs to sell, we subtract S from T:

Remaining oranges = T - S

Substituting the values, we have:

Remaining oranges = 5 kg - 12 kg

Calculating the difference, we get:

Remaining oranges = -7 kg

The result is -7 kg, indicating that the store has sold more oranges (12 kg) than the target amount (5 kg). Therefore, the store needs to sell an additional 7 kilograms of oranges to reach its target.

In the equation form, we can write it as:

Remaining kilograms = Target kilograms - Sold kilograms

= 5 kg - 12 kg

= -7 kg

1.1.3. How many litres of milk does Lihle need to make 120 cupcakes? (2)​

Answers

Lihle would need 30 liters of milk to make 120 cupcakes.

To determine the amount of milk Lihle needs to make 120 cupcakes, we can calculate the total milk requirement by multiplying the milk quantity per cupcake by the number of cupcakes.

Given that the recipe requires 250 milliliters (ml) of milk per cupcake, we can proceed with the calculation:

Convert milliliters to liters:

Since there are 1,000 milliliters in a liter, we divide 250 ml by 1,000 to get the milk quantity per cupcake in liters, which is 0.25 liters.

Multiply the milk quantity per cupcake by the total number of cupcakes: Multiply 0.25 liters (milk per cupcake) by 120 cupcakes.

0.25 liters/cupcake [tex]\times[/tex] 120 cupcakes = 30 liters.

Therefore, Lihle would need 30 liters of milk to make 120 cupcakes in a US curriculum class.

It's important to note that this calculation assumes the given milk requirement of 250 milliliters per cupcake and does not consider any other ingredients or variations in the recipe.

Which transformation represents a reflection over the y = × line?
A. (x, y) - (-x, y)
B. (x, y) -+ (-x, -y)
C. (x,y) → (y, x)
D. (x, y) -+ (y, -x)

Answers

The transformation represents a reflection over the y = × line.

A. (x, y) → (-x, y)

A reflection over the y-axis is a transformation that flips a point or shape across the vertical line y = 0.

This means that points on the right side of the y-axis will be reflected to the left side, and vice versa.

Let's examine each option to determine which one represents a reflection over the y-axis.

A. (x, y) → (-x, y):

This transformation reflects the point across the y-axis.

For example, if we have a point (3, 2), after applying this transformation, it becomes (-3, 2).

This represents a reflection over the y-axis.

B. (x, y) → (-x, -y):

This transformation not only reflects the point across the y-axis but also flips it vertically.

For example, if we have a point (3, 2), after applying this transformation, it becomes (-3, -2).

This represents a reflection over the y-axis.

C. (x, y) → (y, x):

This transformation swaps the x and y coordinates of a point, which does not represent a reflection over the y-axis.

Instead, it represents a 90-degree rotation of the point.

D. (x, y) → (y, -x):

This transformation swaps the x and y coordinates of a point and negates the new x-coordinate.

It does not represent a reflection over the y-axis.

Instead, it represents a 90-degree rotation of the point in the counterclockwise direction.

Based on the explanations above, both options A and B represent a reflection over the y-axis.

According to census the total number of male and female was 88,51,84,692, if number of male was 45,40,34,570 the number of female population is 43,11,50,122.

To find the wide variety of girl population, we will subtract the quantity of male population from the full population.

Total population = 88,51,84,692

Number of male = 45,40,34,570

Number of female = Total population - Number of male

= 88,51,84,692 - 45,40,34,570

= 43,11,50,122

I like to use the FOIL method! I've attached a quick picture of how it works below, but basically you multiply the first terms. Next, multiply the outside/outer terms. Then, multiply the inside/inner terms. Lastly, you multiply the last terms.

In this question, the binomial is (x + 2)².

You can expand this to be (x + 2)(x + 2).

When you expand it using the FOIL method, you get x times x, which is .

Next, the outside/outer terms are x and 2, which is 2x.

Then, you multiply the inside/inner terms 2 and x, which is 2x.

Last, you multiply the last terms, which are 2 and 2, which is 4.

When you put them together, it looks like this:

x² + 2x + 2x + 4.

You can simplify this to x² + 4x + 4.

The value of segment SP in the circle is 13.4.

Given is a circle with chords OP and QR, intersecting S, where QS = 19, QS = 15 and SR = 17 we need to find the value of SP,

To find the value of SP, we can use the property of intersecting chords in a circle, which states that when two chords intersect inside a circle, the product of the segments of one chord is equal to the product of the segments of the other chord.

In this case, we have two chords OP and QR intersecting at point S. Let's denote the lengths of the segments as follows:

QS = 19

QS = x (where S is the intersection of QR and OP)

SR = 17

SP = y (the segment we want to find)

According to the property mentioned above, we have:

QS × QS = QR × SR

15 × 17 = 19 × SP

SP = 15 × 17 / 19

SP = 13.4

Hence the value of segment SP in the circle is 13.4.
