For numbers 3-6 state if the triangles are congruent and if so what method proves they are congruent?​

The symbol for the common normal CDF is. The function represents the CDF of the standard normal distribution.

What is CDF?

The probability function that X will have a value less than or equal to x is known as the Cumulative Distribution Function (CDF) of a real-valued random variable X, evaluated at x. It is employed to describe a table's random variables' probability distribution. And using these data, we can quickly make a CDF plot in an Excel spreadsheet.

So, CDF determines the cumulative probability for the specified value. Under specific circumstances, it is used to compare the probability between values and to ascertain the probability of a random variable. For continuous distribution functions, CDF provides the area under the probability density function up to the specified value, and for discrete distribution functions, it provides the probability values up to what we specify.

F(x)=P(X≤x)=x∫−∞f(t)dt, for x∈R, In other words, integrating the pdf yields the cdf for a continuous random variable. It should be noted that the Fundamental Theorem of Calculus implies that cdf differentiation can be used to determine the pdf of a continuous random variable.

Answer:

9x+15

Step-by-step explanation:

Answer:

Andre has more money in his savings account.

Step-by-step explanation:

  We need to have equations for both Andre and Elena. Andre starts with $100 in his savings and adds $5 per week.  Based on this, Andre's equation will be y = 5x + 100. Elena starts with $10 and adds $20 per week. Based on this, Elena's equation will be y = 20x + 10.

Andre: y = 5x + 100

Elena: y = 20x + 10

We have to figure out who will have more money in their account after 4 weeks. To do that, we plug in 4 into x because x is the number of weeks.

Andre: y = 5(4) + 100

          y = 20 + 100

          y = 120

Andre has $120 after 4 weeks.

Elena: y = 20(4) + 10

         y = 80 + 10

         y = 90

Elena has $90 after 4 weeks.

Which is greater? $120 or $90? That's right, its $120. Andre has more money in his savings account. I hope this helps!

Since 4.286766 is closer to 4 than it is to 8, we can write the final result as: 4.286766 ≈ 2²

We can start by evaluating each bracketed expression first:

{(67)3} = 67 * 67 * 67 = 42,949,769

{(67)2} = 67 * 67 = 4489

Next, we evaluate the first part of the expression:

Rounding to the nearest dollar, Joshua would have $4,129 more in his account than Josiah after 18 years.

To find the amount of money in the account after 18 years,

We can use the formula:

A = P * (1 + r/n)^(nt),

where A is the amount of money in the account,

P is the principal amount ($750),

r is the interest rate (3% or 25%),

n is the number of times the interest is compounded per year (4 or 1), and t is the number of years (18).

For Joshua's account:

A = 750 * (1 + 0.03/4)^(4 * 18)

= 750 * (1.0075)^72

= $1417.15

For Josiah's account:

To solve for t in the equation G = -4t + 100, we need to isolate t on one side of the equation. To do this, we start by subtracting 100 from both sides:

G - 100 = -4t + 100 - 100

Simplifying the right side:

G - 100 = -4t

To find the sum of the digits of all possible values of 'a', we need to add the sum of the digits of each value of abc. The sum of the digits for all possible values of a would be 8 + 7 + 15 + ... + 27, which can be calculated further.

The divisibility rule for 125 states that a number is divisible by 125 if the last three digits are divisible by 125. In the case of 24687abc, we know that the last three digits (abc) must be divisible by 125. This means that abc must be a multiple of 125. The smallest multiple of 125 is 125, and the largest is 999, so the possible values of abc are 125, 250, 375, 500, ..., 999.

The sum of the digits of each possible value of a can be calculated by adding the individual digits of each value of abc. For example, for the value 125, the sum of the digits is 1 + 2 + 5 = 8. For the value 250, the sum of the digits is 2 + 5 + 0 = 7. For the value 375, the sum of the digits is 3 + 7 + 5 = 15.

Therefore , the solution of the given problem of percentage comes out to be 32 liters after 60% increased.

Any value that may be expressed as a fraction of 100 is referred to as a percentage in mathematics. The acronyms "pct.," "pct," or "pc" are also occasionally used. However, the "%" symbol is typically used to denote it. The proportional amount has no dimensions and is flat. Percentages can be viewed as fractions because their numerator is 100. To indicate that a number is a percent, it needs to be followed by the percent symbol (%).

Here,

Given:

=> 20 liters is the given volume

It is increased by 60% ,

then the final volume is :

=> 20 + 60/100 *20

=> 20 + 0.6*20

What is simplification?

Rules are typically rewritten to achieve this simplicity. Systems for computer algebra use them in a methodical way. Associative operations, such as addition and multiplication, can be challenging. It is common practice to approach associativity by assuming that addition and multiplication can have any number of operands, such that the symbol for a + b + c is "+." (a, b, c). It follows that a + (b + c) and (a + b) + c are both condensed to "+"(a, b, c), which is shown as a + b + c.

A zero matrix is a matrix which has all its elements equal to zero. It has a number of special properties that make it useful in linear algebra. For instance, the sum of any two zero matrices is a zero matrix, and any scalar multiple of a zero matrix is a zero matrix. Additionally, the product of two zero matrices is a zero matrix, and the product of a zero matrix and an identity matrix is a zero matrix.

In this instance, the cost of taxi ride is determined by the number of minutes that are used.

For this reason, we design the graph so that the horizontal axis receives values for x (the amount of minutes elapsed) and the vertical scale receives values for c(x), which is the cost.

The number of mins can be any amount over zero but cannot be lower than zero.

The required graph will be produced by calculating c(x) for the at least one or two values and combining the line segment that does not extend below x= 0.

=> x c(x) = 2x + 2

The slope of the secant line over the interval [3, t] for the curve Q(t) = t² is given by the formula m = (t² - 9) / (t - 3).

The slope of a line is a measure of how steep the line is. It tells us how much the line is rising or falling as we move from left to right.

The secant line is a line that passes through two points on a curve. In this case, the curve is Q(t) = t².

To find the slope of the secant line over the interval [3, t], we need to find the slope of the line that passes through the points (3, 9) and (t, t²).

The slope of the line passing through two points (x1, y1) and (x2, y2) is given by the formula:

m = (y2 - y1) / (x2 - x1)

So, using this formula, we can find the slope of the secant line over the interval [3, t]:

m = (t² - 9) / (t - 3)

Answer:

(y + 8)^2

Step-by-step explanation:

To factor the perfect square trinomial "y^2-16y+64" into two binomials, we need to find two binomials that multiply to give the trinomial.

Let's use the formula (y + n)(y + m), where n and m are integers.

If we set n = 8 and m = 8, we get:

(y + 8)(y + 8) = y^2 + 16y + 64

Kareem make muffin using a ratio of 3. 5 cup of flour for every 1. 75 cup of sugar. If he ha 3. 5 cup of sugar, flour doe he need to make the muffin is 7 cups.

The ratio that Kareem uses to make the muffin is 3.5 cups of flour for every 1.75 cups of sugar .

let the number of cups of flour be "y" and

the number of cups of sugar be "x" .

So , y ∝ x ,

y = k*x , where k is the constant of proportionality .

From the given data ,

3.5 = k*1.75

k = 3.5/1.75

k = 2 .

we have to find the cups of flour that Kareem needs , if he has 3.5 cups of sugar .

the equation becomes ,

y = 2*3.5

y = 7

Therefore , Kareem needs 7 cups of flour .
