Answer:

252

Step-by-step explanation:

t50 = t1 + (n - 1)(d)

= 7 + (50 - 1) (5)

= 7 + (49)(5)

= 7 + 245

= 252

Answer:

The 50ᵗʰ term of this sequence is 252

Step-by-step explanation:

Here,

First Term = a₁ = 7

Common Difference = (d) = 5

Now, For 50ᵗʰ term, n = 50

aₙ = a + (n - 1)d

a₅₀ = 7 + (50 - 1) × 5

a₅₀ = 7 + 49 × 5

a₅₀ = 7 + 245

a₅₀ = 252

Thus, The 50ᵗʰ term of this sequence is 252

The probability that a student scores between 450 and 600 on the SAT math section is approximately 0.4147 or 41.47%.

To find the probability that a student scores between 450 and 600 on the SAT math section, we need to use the properties of the normal distribution. We know that the mean is 511 and the standard deviation is 110.

First, we need to standardize the values of 450 and 600 using the formula:

z = (x - μ) / σ

where x is the value we want to standardize, μ is the mean, and σ is the standard deviation.

For 450:

z = (450 - 511) / 110 = -0.55

For 600:

z = (600 - 511) / 110 = 0.81

Next, we need to find the area under the normal curve between these two standardized values. We can use a table or a calculator to find that the area between z = -0.55 and z = 0.81 is approximately 0.4147.

The area of a semi circle is 19.25

We know that,

Area of semicircle = 1/2(πr²)

Therefore,

19.25 = 1/2 * 22/7 * r²

19.25 = 22/14 * r²

19.25 * 14/22 = r²

269.5/22 = r²

12.25 = r²

r = √12.25

r = 3.5 cm

Thus, The radius of the given semicircle is 3.5 cm

Therefore,

Diameter of the given circle = 2 * Radius

Diameter = 2 * 3.5 = 7 cm

Hence, The diameter of the given circle is 7 cm

To convert feet to meters, you will need to multiply the number of feet by 0.3048. This is because one foot is equal to 0.3048 meters.

For example, if you wanted to convert 5 feet to meters, you would multiply 5 by 0.3048. This would give you 1.524 meters. To make a more complex calculation, you can use a calculator or an online conversion tool. These tools allow you to input a value in feet and output the corresponding value in meters.

When dealing with large numbers of conversions, it is sometimes easier to use a conversion table. These tables show the values for feet and meters side-by-side, so you can easily reference the information. Additionally, you can use the table to convert any number of feet into meters.

The probability that John's store will blow up is 1 or 100%.

To calculate the probability of John's store blowing up, we need to consider the probability of drawing three matching balls from the urn filled with 100 numbered ping-pong balls, with replacement.

The probability of drawing a matching ball on the first draw is 1 since there are no restrictions. The second and third draws also need to match the first ball to satisfy the condition. Since we are drawing with replacement, each draw is independent, and the probability of drawing a matching ball on each subsequent draw is also 1.

Therefore, the probability of drawing three matching balls, and thus the store blowing up, is the product of the individual probabilities:

Probability = 1 * 1 * 1 = 1

Hence, this means that no matter which balls John draws, he is guaranteed to draw three matching balls due to the infinite supply of numbered ping-pong balls with replacement. Consequently, the store will always blow up according to the given scenario.

\(-4x^3y^6 + yc^{x^{5}}(ln(c) * 5x^{4}c{x^{4})) / 3y^2 + 6x^4y^5 - c^{x^{5}}\)is the expression for dy/dx for the given equation.

To find dy/dx for the equation y³ + x⁴y⁶ = 5 + ycˣ^⁵, we'll use implicit differentiation. Let's go step by step:

Start by differentiating both sides of the equation with respect to x. d/dx(y³) + d/dx(x⁴y⁶) = d/dx(5) + d/dx(ycˣ^⁵)

Apply the chain rule to each term on the left side of the equation. 3y²(dy/dx) + (4x³y⁶ + 6x⁴y⁵(dy/dx))

= 0 + \((c^{x^{5}}(dy/dx) + yc^{x^{5}}(ln(c) * 5x^{4}c{x^{4}))\)

Simplify the equation:

3y²(dy/dx) + 4x³y⁶ + 6x⁴y⁵(dy/dx) =\((c^{x^{5}}(dy/dx) + yc^{x^{5}}(ln(c) * 5x^{4}c{x^{4}))\)

Group the terms containing dy/dx:

3y²(dy/dx) + 6x⁴y⁵(dy/dx) - \((c^{x^{5}}(dy/dx)\) = -4x³y⁶ + \(yc^{x^{5}}(ln(c) * 5x^{4}c{x^{4}))\)

Factor out dy/dx:

(3y² + 6x⁴y⁵ - \((c^{x^{5})\))(dy/dx) = -4x³y⁶ + \(yc^{x^{5}}(ln(c) * 5x^{4}c{x^{4}))\)

Finally, divide both sides by (3y² + 6x⁴y⁵ - cˣ^⁵) to solve for dy/dx:

dy/dx =\(-4x^3y^6 + yc^{x^{5}}(ln(c) * 5x^{4}c{x^{4})) / 3y^2 + 6x^4y^5 - c^{x^{5}}\)

Therefore, \(-4x^3y^6 + yc^{x^{5}}(ln(c) * 5x^{4}c{x^{4})) / 3y^2 + 6x^4y^5 - c^{x^{5}}\)is the expression for dy/dx for the given equation.

The numerical or verbal descriptions that usually result from measurements are called data or observations.

When measurements are conducted, whether in scientific experiments, surveys, or other data collection processes, the outcome is typically a set of data or observations.

These measurements can be represented numerically, such as numerical values or quantities, or verbally, using descriptive terms or categories.

Numerical descriptions provide precise quantitative information, such as measurements of length, weight, temperature, time, or any other measurable attribute. These measurements are often expressed using numbers or units of measurement.

Verbal descriptions, on the other hand, use words or qualitative descriptions to convey information about the observations.

For example, when conducting a survey, respondents might provide verbal responses that describe their opinions, preferences, or experiences.

To find the unit rate that compares the length of the couch in the dollhouse to the length of the couch in the real living room, we need to convert the measurements to the same unit of measurement. Let's convert the length of the couch in the real living room from feet to centimeters:

1 foot = 30.48 centimeters

So, the length of the couch in the real living room is:

8 feet x 30.48 centimeters/foot = 243.84 centimeters

Now we can calculate the unit rate:

Unit rate = length of couch in dollhouse / length of couch in real living room

Unit rate = 6 centimeters / 243.84 centimeters

Unit rate = 0.0246

Therefore, the unit rate that compares the length of the couch in the living room to the length of the couch in the dollhouse is 0.0246 cm/cm.

Identify the slope and y-intercept of the following equation:

Answer:

x = 7

Step-by-step explanation:

Since the two sides (9x - 25) of the triangle are congruent to each other, we can add them together

(9x - 25) + (9x - 25)

18x - 50

A triangle is 180 degrees when adding all three sides

So if 2 sides together equal 18x - 50 and the last side equals 104, then they should equal 180 total

18x - 50 + 104 = 180

Combine like terms

18x + 54 = 180

Subtract both sides by 54 to isolate the variable

18x + 54 - 54 = 180 - 54

18x = 126

Divide both sides by 18 to isolate the variable

18x ÷ 18 = 126 ÷ 18

x = 7

Check your work by plugging in the x value for the expression and adding all three sides to equal 180 degrees

9(7) - 25 + 9(7) - 25 + 104 = 180

Pemdas says to multiply first

63 - 25 + 63 - 25 + 104 = 180

38 + 38 + 104 = 180

76 + 104 = 180

180 = 180
