Answer:

m + 3.4 kilograms.

Step-by-step explanation:

Let's call the mass of an average man's brain "m" kilograms.

According to the information given, the mass of an average elephant's brain is 3 4/10 kilograms greater than an average man's brain. This means that the mass of an average elephant's brain can be calculated as:

m + 3 4/10 = m + 3.4

So, the mass of an average elephant's brain is 3.4 kilograms greater than the mass of an average man's brain, which is m kilograms.

Therefore, the mass of an average elephant's brain is m + 3.4 kilograms.

Based on the RHS rule of congruency of triangles, APC and APB are congruent, therefore, P lies on the bisector of BAC.

To prove that  P lies on the bisector of BAC:

Based on two equal angles (the bisected angle), right angles, and a similar side, the two triangles are said to be congruent (RHS congruence rule). As a result, the perpendiculars are of equal length, and the angle's bisector is equally spaced from its sides.

Answer:

x = (10.392)

y = 12

Step-by-step explanation:

Trigonometric Functions are special functions relating to the ratio of the sides of triangles. There are 6 primary ones known as sin, cos, tan, csc, sec, cot which all have definitions relating to the sides of a triangle.

We want to use one where it's defined using the adjacent side and opposite side since we know the adjacent side (the side 6) we just don't know the opposite side (the x side).

Luckily we have a function tan which is defined as: [tex]tan(\theta) = \frac{\text{opposite}}{\text{adjacent}}[/tex]

We can plug in values we know: [tex]tan(60) = \frac{x}{6}[/tex] now just multiply both sides by 6 to solve for the x value: [tex]tan(60) * 6 = x[/tex] and then using a calculator we get approximately: ​10.392 and now from here we can use Pythagorean Theorem:

[tex](10.392)^2 + 6^2 = y^2\\\\107.994 + 36 = y^2\\\\143.994=y^2\\\\12=y[/tex]

The domain of the given inequality is y>1.

What do you mean by inequality?

A fundamental idea in social justice theories is inequality, which is the state of not being equal, especially with regard to status, rights, and opportunities.

                              Due to the fact that it frequently has diverse meanings to different people, it can become confusing in public discourse. But there are some similarities as well.

y<√x+3+1

This equation is defined if

    x + 3 ≥ 0

     x ≥ -3

So, the domain of the given inequality is x>-3.

     √x+3 ≥ 0

     √x+3 + 1 ≥ 0 + 1

             y ≥ 1

The points on the boundary line are not included in the solution set. Thus, 1 is not included in the range.

Marshall's total cost number of calls made after 20 days of telemarketing is 1,430, which is the sum of the sequence of 24 calls made on the first day and 119 calls made on the twentieth day.

Marshall has a goal of making 24 calls on the first day of telemarketing and increasing the number of calls by 5 each day for 20 days. This creates an arithmetic sequence which increases by 5 each day. The formula for the sum of an arithmetic sequence is (n/2) × (a + l), where n is the number of terms in the sequence, a is the first term and l is the last term. In this case, n = 20, a = 24, and l = 119. Plugging these values into the formula yields (20/2) × (24+119)= 1,430. This means that Marshall's total number of calls made after 20 days of telemarketing is 1,430, which is the sum of the sequence of 24 calls made on the first day and 119 calls made on the twentieth day.

Answer:

Step-by-step explanation:

Find the probability that X is less than 92:

We can use the cumulative distribution function (CDF) of a normal distribution to find the probability that X is less than 92. The CDF of a normal distribution with mean μ and standard deviation σ is given by:

F(x) = (1/2) * [1 + erf((x-μ)/(σ * sqrt(2)))]

Where erf is the error function.

So, the probability that X is less than 92 can be calculated as:

P(X < 92) = F(92) = (1/2) * [1 + erf((92-108)/(17 * sqrt(2)))]

This value can be calculated using a calculator or statistical software.

Find the probability that X is between 92 and 126:

We can use the CDF to find the probability that X is between 92 and 126. The probability that X is between 92 and 126 is equal to the difference between the CDF values at 126 and 92:

P(92 < X < 126) = F(126) - F(92)

This value can also be calculated using a calculator or statistical software.

Find the IQ of an individual that is in the top 10% of the population:

To find the IQ of an individual that is in the top 10% of the population, we need to find the value of X that corresponds to a cumulative probability of 0.9. This can be done by solving for X in the CDF equation:

F(X) = 0.9

X = μ + σ * inverse_CDF(0.9)

Where inverse_CDF is the inverse cumulative distribution function and can be calculated using a calculator or statistical software. The value of X that corresponds to a cumulative probability of 0.9 is the IQ of an individual that is in the top 10% of the population.

Quantitative data is data that is measured on a naturally occurring numerical scale.

This can be seen in the data input as 1, 2, 3, 4, which can be meaningfully added, subtracted, multiplied, or divided. Qualitative data, on the other hand, is data that cannot be meaningfully added, subtracted, multiplied, or divided. The data set consisting of classifications AB, C, and D is qualitative because it can only be classified into categories and cannot be meaningfully added, subtracted, multiplied, or divided. To illustrate this further, let’s take an example. If the categories are colours (A = Red, B = Blue, C = Green, and D = Yellow), the data set AB, C, and D cannot be meaningfully added, subtracted, multiplied, or divided, and therefore is qualitative.

Therefore, the annual simple interest rate charged by the pawnbroker is 5%

To determine simple interest, divide the balance by the cost of borrowing, the amount of time left, and other factors. Principal plus interest plus hours is the straightforward return strategy in marketing. The simplest approach to calculate interest is to use this method. The most popular method of calculating revenue is as a percent of the principal amount.

Here,

To find the annual simple interest rate, we need to use the formula:

Simple interest = Principal x Rate x Time

where Principal is the amount borrowed, Rate is the interest rate, and Time is the time period in years.

In this case, the Principal is $270, and the amount paid back is $276.75, which means the interest paid is:

Interest = Amount paid back - Principal = $276.75 - $270 = $6.75

The time period is 5/360 years, since there are 360 days in a year and Elisa had the loan for 5 days.

Plugging these values into the formula, we get:

$6.75 = $270 x Rate x 5/360

Solving for Rate, we get:

Rate = $6.75 / ($270 x 5/360) = 0.05 or 5%

Therefore, the annual simple interest rate charged by the pawnbroker is 5%

When you borrow money, you must pay interest, and you need to lend money when you lend it. Typically, interest is determined as an indicator of the overall of the loan total. The loan's interest is the term given to this percentage.

A = P(1 + r)ⁿ

A is the sum, P is the sum at the beginning, r is the interest rate, and n is the number of years.

Jo took out a four-month loan from a bank for 3,800. The bank applied a 5.5% discount to the loan.

The true interest rate is going to be

r = 5.5% / 12

r = 0.458%

When this happens, the money the bank gets is equivalent to what Jo paid in interest.

I = P(1 + r)ⁿ - P

I = 3800 (1 + 0.055/12)⁴ - 3800

I = $3870.14 - $3800
