Answer:

5 is the *estimate*

Answer: Choice D

Step-by-step explanation:

When we think of proportional relationships, we can think of ratios. The x and y value will be multiplied by the same ratio throughout the table to create equivalent points. The easiest way to do this is to turn the points into fractions and see if they all simplify to the first point, which in this case is 2/3.

4/6 / 2/2 = 2/3

6/9 / 3/3 = 2/3

8/12 / 4/4 = 2/3

2 is being added to the x value each time and 3 is being added to the y value each time. hope this helps!

The angle made by the ladder with the truck is 61.78°

Trigonometric Ratios are defined as the values of all the trigonometric functions based on the value of the ratio of sides in a right-angled.

Given that, The ladder of a fire truck is extended to reach a window of an apartment complex. The ladder is extended to a length of 55 feet and is attached to the truck bed which is 26 feet from the building.

The situation is creating a right triangle, hence, using trigonometric ratio,

Since, we know, the cosine of an angle is the ratio of adjacent side to hypotenuse.

Therefore, cosx = 26 / 55

x = cos⁻¹(26 / 55)

x = 61.78°

Hence, the angle made by the ladder with the truck is 61.78°

Answer:

[tex]92.0 in.^{2}[/tex]

Step-by-step explanation:

To do this, we will use the following equation:  [tex](A_{I}) = \frac{598}{6.5} \frac{cm^{2}}{cm^{2} /in.^{2} }[/tex]

where [tex]A_{I}[/tex] represents the area of the paper in inches.\

Next, divide the numerical value of 598 by 6.5, receiving the quotient [tex]\frac{598}{6.5} \frac{cm}{cm/in.^{2} } = 92.0 \frac{cm}{cm/in.^{2} }[/tex].

Cancel the [tex]cm^{2}[/tex] (square centimeters unit) existing in both the numerator and the denominator, thereby leaving [tex]92.0 \frac{1}{1/in.^{2} }[/tex].

Finally, since the inverse of the inverse of a number is that same number itself ([tex]\frac{1}{1/b} = b[/tex]), we rewrite the measuring units of this quotient as [tex]92.0 in.^{2}[/tex].

Now our answer is clean and finalized for submission.

If probability  each parent is heterozygous for both features, determine the likelihood that a child will only have cystic fibrosis or sickle-cell anaemia.

P(Sickle-cell Anemia)

= 0.25

P(Cystic Fibrosis)

= 0.25

P(Sickle-cell Anemia or Cystic Fibrosis) = P(Sickle-cell Anemia) + P(Cystic Fibrosis)

P(Sickle-cell Anemia or Cystic Fibrosis)

= 0.25 + 0.25

P(Sickle-cell Anemia or Cystic Fibrosis)

= 0.5

The likelihood that a child will have either cystic fibrosis or sickle-cell anaemia is 0.5 or 50%. This is because both parents are heterozygous for both features. This means that each parent has a 25% chance of passing on either one of the conditions to their child. The probability of having either one of the conditions is the sum of the individual probabilities, which is 0.25 + 0.25 = 0.5 or 50%.

Using the unitary approach, an issue can be resolved by first figuring out the value of a single unit, then multiplying that value by the number of units needed to solve the problem. The unitary technique is sometimes useful for multiplying and dividing by fractions because it makes sense immediately and can be done mentally if the numbers add up. This makes it a good method for defending or explaining frequently employed written fractional algorithms, like division by a fraction. The unitary technique has a formula that involves finding the value of a single unit, multiplying it by the quantity of units, and then finding the desired value.

given

For his 10-gallon punch, Matt uses gallons of orange juice, which adds up to 3x=3*2 = 6.

Using the formula Jan uses gallons of orange juice to create 10 gallons of punch and Matt uses gallons of orange juice to make 10 gallons of punch, we can calculate that Jan uses 2 gallons more orange juice than Matt.

We can multiply both the numerator and denominator by 12.5 to get the equivalent fraction:

5/8 = 62.5/100

We want to rewrite 5/8 as an equivalent fraction with a denominator of 100.

Remember that if we multiply both the numerator and denominator of a fraction by the same number, then we will get an equivalent fraction.

So if that number is x, we can write:

5/8 = (5*x)/(8*x)

First, we want a denominator of 100, then the value of x must be such that:

8*x = 100

x = 100/8

x = 12.5

Answer: ahh.

Step-by-step explanation:

Answer:

To find the volume of the gas at a pressure of 0.40 atm if the temperature is held constant, we can use the ideal gas law:

PV = nRT

Where P is the pressure of the gas, V is the volume of the gas, n is the number of moles of gas, R is the ideal gas constant, and T is the temperature of the gas.

Since the number of moles and the temperature of the gas are constant, we can rearrange the equation to solve for V:

V = (nRT)/P

Plugging in the given values, we have:

V = (nRT)/P = (nRT)/(0.40 atm)

We know that the original volume of the gas was 0.50 L, so the new volume will be:

V = (0.50 L)(0.20 atm)/(0.40 atm) = 0.50 L / 2 = 0.25 L

So the volume of the gas at a pressure of 0.40 atm will be 0.25 L. The correct answer is A) 0.25 L.

Answer:

A) 0.25 L

Step-by-step explanation:

Use Boyle's Law:

[tex] P_1V_1 = P_2V_2 [/tex]

[tex] 0.20~atm \times 0.5~L = 0.40~atm \times V_2 [/tex]

[tex] V_2 = \dfrac{0.20~atm \times 0.5~L}{0.40~atm} [/tex]

[tex] V_2 = 0.25~L [/tex]

The chance that you will get a heads or tails when you flip a coin once (option A) is not mutually exclusive.

Mutually exclusive events are events that cannot occur at the same time, or that do not have any overlap. In the case of flipping a coin, the possibility of getting a head and the possibility of getting tails are independent of each other, and both can occur simultaneously. Therefore, the chance that you will get heads or tails when you flip a coin once is not mutually exclusive.

On the other hand, the other events listed (B, C, and D) are mutually exclusive. The chance that you will only study for the test alone or with a friend cannot occur simultaneously, as you can either study alone or with a friend, but not both. Similarly, the chance that you will meet your friends for pizza or at a Chinese restaurant for dinner today at 6 cannot occur at the same time, as you can either go to the pizza place or the Chinese restaurant, but not both.

this question is related to probability.

mutually exclusive

Mutually exclusive events are those events that do not occur at the same time.

For example, when a coin is tossed then the result will be either head or tail, but we cannot get both the results. Such events are also called disjoint events since they do not happen simultaneously.

The function is increasing on the open interval (0, 2Ï€) and decreasing on the open interval (-2Ï€, 0).

The derivative of a function tells us the slope of the function at any given point, and the sign of the derivative tells us whether the function is increasing or decreasing at that point. If the derivative is positive, the function is increasing at that point, and if the derivative is negative, the function is decreasing at that point.

The function f(x) = sin(x) + 9 is increasing on the interval (0, 2π) because the derivative of sin(x) is positive on this interval. The derivative of sin(x) is cos(x), which is positive for all values of x except for multiples of π.

The length of the shadow when the sun altitude is 60 degrees is 8.7 feet.

The clock tower is 15 feet tall. The length of the shadow when the sun is at an altitude of 60 degrees can be calculated as follows:

This situation forms a right angle triangle.

Hence, using trigonometric ratios,

tan 60 = opposite / adjacent

where

opposite side = 15 feet

adjacent side = x

tan 60 = 15 / x

cross multiply

x tan 60° = 15

divide both sides by tan 60

x = 15 / tan 60

x = 15 / 1.73205080757

x = 8.65800865801

x = 8.7 feet
