five birds were perched on a branch could half of the fly away why or why not​

Answer:

8 weeks

Step-by-step explanation:

Ok, so the equation given is y=8x+40

If the school needs 104 cabinets in total, we have to find x, the number of weeks to complete this order.

We can input 104 as y as that's the total:

104=8x+40

We have to isolate x, so first, subtract 40 from both sides

64=8x

Next, divide both sides by 8

8=x

So, it will take 8 weeks to fulfill this order.

The experimental probability of drawing a spade is 0.2

When we perform an experiment N times, and we got a given outcome K times, the experimental probability of said outcome is given by the quotient:

P = K/N

The polynomial p(x) has option (c) three real zeros because it has a relative maximum at (-2, 4), a relative minimum at (1,1), a relative maximum at (5,7), and a negative leading coefficient.

Since p(x) has a relative maximum at (-2, 4), a relative minimum at (1,1), and a relative maximum at (5,7), it means that the degree of the polynomial must be odd and at least three.

Moreover, we know that p(x) has no other critical points. This means that p(x) does not change sign between these relative extrema, which in turn implies that there are no real zeros between these extrema.

Therefore, the number of real zeros of p(x) is either one or three. To determine the answer, we need to consider the leading coefficient of p(x).

If the leading coefficient is positive, then p(x) must eventually increase on both ends, since the degree is odd. This means that there is exactly one real zero.

If the leading coefficient is negative, then p(x) must eventually decrease on both ends. In this case, since there are three relative extrema, there must be three real zeros.

Thus, we need to find the sign of the leading coefficient of p(x). This can be done by looking at the relative extrema.

Since p(x) has a relative maximum at (-2, 4), we know that the leading coefficient is negative.

Therefore, the correct option is (c) three.

Answer:

We can start by calculating the total amount of money earned per week:

$12.50/hour x 25 hours/week = $312.50/week

To find out how many weeks it will take to earn $3,437.50, we can set up a proportion:

Total amount earned / Amount earned per week = Number of weeks

$3,437.50 / $312.50/week = 11 weeks

Therefore, it will take 11 weeks to earn $3,437.50 working 25 hours per week at a rate of $12.50 per hour.

Problem 1: The best approximation for finding the price of an individual product is (b) Marginal Cost. This is because marginal cost represents the cost of producing one additional unit of the product. Problem 2: You get profit when (c) Revenue is more than cost. When the revenue generated from selling products is greater than the cost of producing those products, you will have a positive profit.

For problem 1, the best approximation for finding the price of an individual product would be the Marginal Cost. This is because it takes into account the additional cost of producing one more unit of the product, which directly affects the price.

For problem 2, the correct answer would be c) When Revenue is more than cost. This is because profit is calculated by subtracting the cost of producing the product from the revenue earned from selling it. If the revenue is higher than the cost, then there is profit. If the cost is higher than the revenue, then there is a loss. When the cost is equal to the revenue, there is no profit or loss, just a break-even point.

A = 10ft

B = 13ft

height = 7ft

area of two trapezoid side = 2[1/2 × (10 + 13) ft × 7 ft = 161 ft²

area of rectangle with length 15ft and width 8ft = 8 ft × 15 ft = 120 ft²

area of rectangle with length 15ft and width ft = 15 ft × 105 ft = 105 ft²

area of rectangle with length 15ft and width 13ft = 15 ft × 13 ft = 195 ft²

area of rectangle with length 15ft and width 10ft = 15 ft × 10 ft = 150 ft²

surface area of the trapezoid = 161 ft² + 120 ft² + 105 ft² + 195 ft² + 150 ft² = 731 ft².

The proportion of cherry tomatoes that are rejected based on their diameter is 0.0033. (option a).

To use the CDF, we need to standardize the diameter values using the z-score formula:

z = (x - μ) / σ

where z is the z-score, x is the diameter value, μ is the mean diameter, and σ is the standard deviation.

For tomatoes with a diameter of at most 15 mm, we have:

z = (15 - 22) / 2.5 = -2.8

For tomatoes with a diameter of at least 30 mm, we have:

z = (30 - 22) / 2.5 = 3.2

Next, we use the z-table to find the area under the Normal distribution curve that corresponds to these z-scores. For a z-score of -2.8, the area is 0.0026. For a z-score of 3.2, the area is 0.9993.

Finally, we add these two areas together to get the total proportion of rejected tomatoes:

proportion = 0.0026 + (1 - 0.9993) = 0.0033

According to the given information, we know that:

Force (F) is constant

Mass (m) of the first object is 4 kg, and its acceleration (a) is 13 m/s².

Using Newton's second law of motion, we know that:

F = m*a

Solving for the force (F) acting on the first object:

F = m*a = 4 kg * 13 m/s² = 52 N

Now, if the same force acts upon an object with a mass of 26 kg, we can use the same equation to find its acceleration (a):

F = m*a

a = F/m

a = 52 N / 26 kg = 2 m/s²

Circle with center C and point D. Triangle CDE and triangle CDF are both equilateral, and we have DE = EF = FD.

What is construction?

In the context of geometry, construction refers to the process of creating geometric figures or shapes using only a compass and straightedge (also called a ruler). The goal of construction is to create accurate and precise geometric figures using only these two tools and a given set of instructions.

To construct an equilateral triangle DEF with points E and F on circle C, we will follow the following steps:

Step 1: Draw a circle with center C and point D on it.

Step 2: Draw a line through points C and D. This line will be the base of our equilateral triangle DEF.

Step 3: Construct the perpendicular bisector of line CD. This can be done by drawing two circles with centers at C and D, both with radius greater than half the length of CD. The two circles will intersect at two points, and the line passing through these two points will be the perpendicular bisector of CD.

Step 4: Let G be the intersection point of the perpendicular bisector and circle C that is closest to point D. Draw lines from G to points C and D. These lines will intersect circle C at points E and F, respectively.

Step 5: Check that the length of CE is equal to the length of CF. This can be done using a compass and ruler.

Step 6: Finally, draw lines from points E and F to point D. The resulting triangle DEF will be equilateral.

To prove that triangle DEF is equilateral, we can show that DE = EF = FD. We already know that CE = CF from step 5. Since C is the center of the circle, CE = CF = CD. By construction, angle ECD and angle FCD are both 60 degrees, since they are inscribed angles that intercept the same arc.

Therefore, triangle CDE and triangle CDF are both equilateral, and we have DE = EF = FD.

Skewness measures the magnitude, degree, and direction of asymmetry in a distribution. It is an important tool for describing and understanding the shape of data distributions.

Skewness is a measure of the asymmetry of a distribution. It is a statistical measure that indicates the degree to which a distribution deviates from the symmetry of a normal distribution. Skewness can be either positive or negative, or it can be zero, indicating no skewness.

Magnitude, The magnitude of skewness is determined by the degree of asymmetry in the distribution. The larger the magnitude of skewness, the more asymmetrical the distribution is. A small magnitude indicates a distribution that is close to symmetric.

Degree, The degree of skewness is the extent to which the distribution deviates from symmetry. Positive skewness indicates a distribution with a longer right tail than left, while negative skewness indicates a distribution with a longer left tail than right.

Direction, The direction of skewness is the direction of the longer tail of the distribution. If the tail is to the right, the distribution is positively skewed, and if the tail is to the left, the distribution is negatively skewed.

The probability of rolling an even number on a dice is 1/2, since there are three even numbers (2, 4, and 6) out of a total of six possible outcomes (1, 2, 3, 4, 5, and 6).

The probability of landing on tails when flipping a coin is also 1/2, since there are only two possible outcomes (heads or tails) and they are equally likely.

To find the probability of both events happening together, we need to multiply their probabilities:

1/2 (probability of rolling an even number) x 1/2 (probability of landing on tails) = 1/4

Therefore, the probability of rolling an even number on a dice and landing on tails when flipping a coin is 1/4 or 0.25 (25%).

Equation for Angle 3- 90-38=52

Angle 3= 52

Angle 5= 38

Angle 6= 52

Step-by-step explanation:

Angle is 90 degrees.

Angle 2 is 38 degrees.

If you are just looking at the bottom half(Angle 6, Angle 1, and Angle 2) They are all supposed to add up to equal 180 degrees because it is a supplementary angle.

So you add 90 and 38 and it gives you 52(Angle 6).
90+38+52=180

Then a complementary angle is two angles that equal 90 degrees.

So if you take Angle 2(38 degrees) and subtract it from 90, you get 52. Which is Angle 3.

You do the same with Angle 6 and Angle 5.

Angle 6(52 degrees) subtract from 90 and you get 38.

Then you add 38 and 52 and you get 90.

Then 180-90=90, so Angle 4 is 90 degrees.
