Answer:

Step-by-step explanation:

Answer:

Almonds = 400grams

Cashew = 300 grams

Step-by-step explanation:

Let the grams of cashew be represented by = C

the grams of almonds be represented by = A

A 700 g dry fruit pack costs ₹216 .It contains some almonds and the rest cashew kernel

C + A = 700g ......Equation 1

C = 700 - A

If almonds cost ₹288 per kg and cashew kernel cost ₹336 per kg

Let's convert them to grams

1 kg = 1000grams

For almonds

= 288/1000 = 0.288g

For cashew

= 336/1000 = 0.336g

Hence,

0.288 × A + 0.336g × C = ₹216

0.288A + 0.336C = 216

From Equation 1, substitute 700 - A for C in Equation 2

0.288A + 0.336(700 - A) = 216

0.288A + 235.2 - 0.336A = 216

Collect like terms

0.288A - 0.336A = 216 - 235.2

- 0.048A = -19.2

A = -19.2/-0.048

A = 400 grams

Substitute 400g for a in Equation 1

C + A = 700g ......Equation 1

= C + 400g = 700g

C = 700g - 400g

C = 300g

Therefore, the number of grams of Almonds = 400grams

Cashew = 300 grams

In general, different refrigerants should not be mixed or recovered into the same cylinder.

Different refrigerants have unique chemical compositions and properties that make them incompatible with one another. Mixing different refrigerants can lead to unpredictable reactions, loss of refrigerant performance, and potential safety hazards. Therefore, it is generally recommended to avoid recovering different refrigerants into the same cylinder.

When recovering refrigerants, it is important to use separate recovery cylinders or tanks for each specific refrigerant type. This ensures that the refrigerants can be properly identified, stored, and recycled or disposed of in accordance with regulations and environmental guidelines.

The refrigerant recovery process involves capturing and removing refrigerant from a system, storing it temporarily in dedicated containers, and then transferring it to a proper recovery or recycling facility. Proper identification and segregation of refrigerants during the recovery process help maintain the integrity of each refrigerant type and prevent contamination or cross-contamination.

To maintain the integrity and safety of different refrigerants, it is best practice to recover each refrigerant into separate cylinders. Mixing different refrigerants in the same cylinder can lead to complications and should be avoided. Following proper refrigerant recovery procedures and guidelines helps ensure the efficient and environmentally responsible management of refrigerants.

The hare can afford to nap for approximately 3686.33 seconds if he does not want to lose the race.

We can use the time it takes the hare to run 100 m to determine how long he can afford to nap.

First, let's find the time it takes the hare to run the 100 m:

t = d / v

Where t is the time, d is the distance, and v is the velocity (speed) of the hare.

t = 100 m / 15 m/s

t = 6.67 s

Next, let's find the time it takes the tortoise to run 1 km (1000 m):

t = d / v

Where t is the time, d is the distance, and v is the velocity (speed) of the tortoise.

t = 1000 m / 0.27 m/s

t = 3700 s

So, the time it takes the tortoise to run the race is 3700 s. The time it takes the hare to run the first 900 m is 7 s. Therefore, the time the hare has left to nap is:

3700 s - 7 s = 3693 s

And the time it takes the hare to run the last 100 m is 6.67 s. Therefore, the hare can afford to nap for:

3693 s - 6.67 s = 3686.33 s

So, the hare can afford to nap for approximately 3686.33 seconds if he does not want to lose the race.

The volume of a solid right pyramid can be calculated using the formula \(V = (1/3) \times base area \times height\).

In this case, the base of the pyramid is a square with an edge length of x cm, which means the base area is \(x^2\)square cm. The height of the pyramid is y cm.

So, the expression that represents the volume of the pyramid is:

\(V = (1/3) * x^2 * y \text{cubic cm}\)

This formula calculates the volume of a solid right pyramid with a square base, where x is the length of the base edge and y is the height of the pyramid. To find the volume, you need to multiply the base area (\(x^2\)) by the height (y) and divide the result by 3. The volume will be expressed in cubic centimeters (\(cm^3\)).

For example, if the base edge length is 4 cm and the height is 6 cm, the volume would be:

\(V = (1/3) \times (4^2) \times 6 = (1/3) \times 16 \times 6 = 32 cm^3\)

So, the volume of the pyramid would be 32 cubic centimeters.

RNA's capability to self-replicate and catalyze chemical reactions make it the best candidate for the first life-form.

According to the scientists, RNA is considered the best candidate for the first life-form due to the fact that RNA is capable of self-replication and catalysis. This is possible because RNA can act both as a template to produce copies of itself and also as an enzyme to accelerate chemical reactions. These abilities suggest that RNA could have played a role in the emergence of the first living organisms on Earth.

An RNA molecule has the ability to catalyze reactions, which means that it can speed up chemical reactions without itself being altered. Thus, it is capable of serving as an enzyme. Scientists believe that the first life-form must have been capable of self-replication and catalysis, and RNA is capable of both functions.

This capability is significant because it is fundamental for the origin of life. Hence, RNA is believed to have played a significant role in the emergence of the first living organisms on Earth.

To conclude, RNA's capability to self-replicate and catalyze chemical reactions make it the best candidate for the first life-form.

answer:

sum: 19 + 7 = 26

difference: 19 - 7 = 12

step-by-step explanation:

the sum of x and y is 26. in other words, x plus y equals 26 and can be written as equation a:

x + y = 26

the difference between x and y is 12. in other words, x minus y equals 12 and can be written as equation b:

x - y = 12

now solve equation b for x to get the revised equation b:

x - y = 12

x = 12 + y

then substitute x in equation a from the revised equation b and then solve for y:

x + y = 26

12 + y + y = 26

12 + 2y = 26

2y = 14

y = 7

now we know y is 7. this means that we can substitute y for 7 in equation a and solve for x:

x + y = 26

x + 7 = 26

X = 19

Step-by-step explanation:

You want an expression equivalent to p/6 +(7 +8).

The associative property of addition lets you move the parentheses in a sum. This means ...

  \(\dfrac{p}{6}+(7+8)\equiv\boxed{\left(\dfrac{p}{6}+7\right)+8}\)

__

Additional comment

The sum (7+8) is not 1, so the first answer option doesn't apply.

8 is not a factor in the expression, so the second answer option doesn't apply.

p/6 is not the same as 6p, so the last answer option doesn't apply.

The given distribution is not a probability distribution, since the sum of probabilities is not equal to 1 and since at least one of the probabilities is greater than 1 or less than 0. Therefor, the correct answer is B and D.

A probability distribution is a statistical function that shows the possible values of a random variable and their associated probabilities. Probability distributions are divided into two types: discrete and continuous. A probability distribution is also known as a probability density function or a probability mass function, and it can be graphically represented as a histogram, bar graph, or line chart.

A probability distribution for a random variable is a set of probabilities and their respective probabilities. The sum of the probabilities in a probability distribution must be equal to 1.

The sum of the probabilities is not equal to 1 i.e., 0.05 + 1.05 + 0.35 + 0.55 = 2

Another condition of probability distribution is that probability of any random variable should not be greater than 1 or less than zero. At least one of the probabilities is greater than 1 (1.05 > 1), which violates the condition for a probability distribution.

When the sum of probabilities is not equal to 1, it means that the given distribution is not a probability distribution (Option B). When at least one of the probabilities is greater than 1 or less than 0, it means that the given distribution is not a probability distribution (Option D).

Note: The question is incomplete. The complete question probably is: Determine whether or not the distribution is a probability distribution and select the reason(s) why or why not. Select all that apply.

The values of the t statistic that are statistically significant at the α=0.005 level are t < -2.977 or t > 2.977.

To determine the values of the t statistic that are statistically significant at the α=0.005 level, we need to find the critical values of the t-distribution with 14 degrees of freedom (df = n - 1 = 15 - 1 = 14).

Using a t-table or a calculator, we can find that the critical values for a two-tailed test with α=0.005 are -2.977 and 2.977. This means that any t statistic less than -2.977 or greater than 2.977 would be considered statistically significant at the α=0.005 level.

In other words, if the calculated t statistic falls within the range of -2.977 to 2.977, we would fail to reject the null hypothesis (H0: μ=10) and conclude that there is not enough evidence to suggest that the population mean is different from 10. However, if the calculated t statistic falls outside of this range, we would reject the null hypothesis and conclude that there is evidence to suggest that the population mean is different from 10.

So, the values of the t statistic that are statistically significant at the α=0.005 level are t < -2.977 or t > 2.977.
