1 odd number

2 prime number

3 odd number and prime number

4 none (is out of the diagram)

5 odd number and prime number

Answer:

Ok here's the answer

Step-by-step explanation:

Odd numbers are whole numbers that cannot be divided exactly into pairs. Odd numbers, when divided by 2, leave a remainder of 1. 1, 3, 5, 7, 9, 11, 13, 15 … are sequential odd numbers. Odd numbers have the digits 1, 3, 5, 7 or 9 in their ones place.

Here are the first few prime numbers: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97, 101,

so you need to put 1 in the odd number section

put 2 in the prime number section

put 3 in the middle section which is the similarities

don't put 4 anywhere because it's neither an odd number nor a prime number

put 5 in the middle section which is the similarities

Answer:

Answer:

It is 4 feet below the tree limb now

step by step

it starts at -23 or 23 below and rises 19 or adds 19 to the -23

so -23+19=-4. or 4 feet below the tree limb

Final answer:

After floating up 19 feet from its initial position of 23 feet below the tree limb, the balloon is 4 feet below the limb.

Explanation:

The student's question pertains to finding out the position of a balloon relative to a tree limb if the balloon starts 23 feet below the tree limb and then floats up 19 feet. We begin by acknowledging that the balloon's initial position is -23 feet (since it is below the limb, we consider this as negative). Upon floating up 19 feet, we perform the arithmetic operation of adding +19 feet to the initial position.

The calculation is as follows: -23 feet + 19 feet = -4 feet.

Therefore, the balloon's final position relative to the tree limb is 4 feet below it, since the result is still negative, indicating that the balloon did not reach or surpass the height of the limb.

Answer:

I'm not sure how to answer is but i think its called   < CDE  or  < EDC  or it is an acute angle.

Step-by-step explanation:

The two ways of naming the given angle are:

There are two general ways of naming an angle.

First, we just call the angle as the vertex. For example, in this case the vertex is D, then the name of the angle would be D or ∠D, where the symbol ∠ is used for angles.

Now, there are another way of naming an angle, and it depends on the arms of the angle (in cases where a point is a common vertex for many angles, we need to specify the arms).

So the name would be:

EDC or ∠EDC

Where the vertex goes always in the middle.

Answer:

a = 3

b = 4

c = 5

Step-by-step explanation:

This is a rhombus. A property of a rhombus is that their diagonals perpendicularly bisect each other. In other words, if the point in the center is A, then HA = MA and EA = OA. So: 3 = a and 4 = b.

Since angle HAO forms a right angle, we can use the Pythagorean Theorem to say that HA^2 + AO^2 = OH^2: 3^2 + 4^2 = 9 + 16 = 25.

OH^2 = 25

OH = 5

Hope this helps!

Answer:

a = 3

b = 4

Answer:

The option which is an exception is;

c) The sample sizes are large

Step-by-step explanation:

Here the requirement to perform a two sample t procedure are as follows;

1. The two samples have equal variance, hence the variance should be known

2. The samples for which the two sample t procedure is performed must be independent

3. The data are in alignment with the normal distribution probability

4. The samples are random samples taken from the different respective population

Since the sample size is known, we do not assume that the sample size are large.

Therefore options a), b) and d) are all correct except option c).

Answer:

The deer population in 1920 is 104000

Step-by-step explanation:

Here we have the deer population is given approximately by the following equation;

Population of deer = -0.125·x⁵ + 3.125·x⁴ + 4000

Where x = number of years from 1900

Therefore, in 1920, we have x = 20

Hence, the deer population in 1920 is then

-0.125·20⁵ + 3.125·20⁴ + 4000

Which gives

-400000 + 500000 + 4000 = 104000

The deer population in 1920 is therefore, 104000.

We can begin by noting a few things:

• dB represents the sound intensity in decibels

• I represents intensity

• I0 represents reference intensity

Assuming the reference intensity (I0) is the base level of hearing represented by the equation 1 • 10^(-12) watts per meter^2, we can incorporate 100 into the equation.

If the sound intensity of rustling leaves (I) is 100 times the reference intensity (I0), we can set up an equation to solve:

I = 100 • 10^(-12)

Now to calculate the intensity of rustling leaves in decibels:

dB = 10 • log10(100 • (1 • 10^(-12)) / (1 • 10^(-12)))

dB = 10 • log10(100) = 10 • 2 = 20 dB

Therefore, the sound intensity of rustling leaves is 20 decibels.

Answer:

See below.

Step-by-step explanation:

Write the sec's as 1 / cos  and the tan's as sin / cos

I will write sin as s and cos as c:

Left side  =  1 / ( cos)a - b)  =     1  / (ca cb + sa sb)

Right side =    1  /  (  ca cb ( 1 + sa sb / ca cb))

The 'ca cb' cancels out so

Right side = 1 / (ca cb + sa sb)  = left side..

Answer:

P=x/2.2

Step-by-step explanation:

We can create an equation to solve this.

Let the number of pounds be P

Let the number of kilograms be X

Now, we know that for 1 kilogram, there is 2.2 pounds.

Therefore if we have 1 kilogram (X) then we will have 2.2 pounds (P).

X=2.2P

All you have to do now is rearrange the equation to find the number of pounds in x kilograms. To do this divide both sides by 2.

Therefore you will get P=x/2.2

The number of pounds in X kilograms can be obtained by using the proportional relationship, Hence, the number of pounds in X kilograms is 2.2X pounds

Given the Parameters :

Creating the proportional expression thus :

1 kilogram = 2.2 pounds

X kilograms =?

Cross multiply :

Number of pounds = 2.2X

Therefore, there will be 2.2X pounds in 1 kilogram.

Step-by-step explanation:

Both x and y have the exponent 1, and therefore this is a LINEAR equation.  NO, it is not an exponential function.

Final answer:

The function y=7x-3 is not an exponential function; it is a linear function with a slope of 7 and a y-intercept of -3.

Explanation:

The function given is y=7x-3. To determine whether this function is exponential, we should look at the form of the function. An exponential function has the form y = abˣ, where a is a constant, b is the base of the exponential (which is a positive real number other than 1), and x is the exponent. The given function, however, is a linear function because it can be rewritten in the form y = mx + b, where m is the slope and b is the y-intercept. In this case, m (the slope) is 7, and b (the y-intercept) is -3. Therefore, y=7x-3 is not an exponential function; it is linear.

Answer: (a) 12.44 - 3.11h = 0

(b) 4in²

Step-by-step explanation:

Area of a triangle = (1/2)bh, where b is the base and h is the height.

Now from the question, Area = 6.22in² and the base is 3.11inches.

Therefore, the equation that relates the area to the height and the base wiil be

Area = (3.11)h/2

6.22 x 2 = 3.11 x h

12.44 = 3.11h

12.44 - 3.11h = 0

(b) to find the value of h from the equation, make h the subject of the formula by solving for h

12.44 = 3.11h

h = 12.44/3.11

Step-by-step explanation:

In a perfectly competitive market, Andy will produce two basketballs in the short run, as this is the quantity at which the marginal cost equals the equilibrium price of $2.50.

In a perfectly competitive market, a firm like Andy's basketball business should continue to produce and sell its product as long as the marginal cost (MC) of producing an additional unit is less than or equal to the market price, and stop at the point where MC equals the market price. Given that the equilibrium price of basketballs is $2.50, and looking at the provided information where various costs are outlined, we can determine how many basketballs Andy should produce.

Andy should look at the marginal cost for each output level and compare it to the equilibrium price. He will produce up to the point where marginal cost equals the equilibrium price. The table shows the last unit he should produce at a marginal cost of $2.50 is the second basketball. Producing the third basketball would have a marginal cost of $5.00, which is higher than the equilibrium price, indicating that producing the third basketball would lead to a loss. Therefore, in the short run, Andy will produce two basketballs per day.
