Answer:

205 because 8.4% of 17.22 is 205

The correct option is, Mickey should have added –4 and 2 when combining the coefficients of the x terms.

Given,

The expression;  2x² - 4x - 9 - x² + 2x + 3

We have to simplify the expression;

To group and arrange an expression in such a way that it is easier to understand and solve is to simplify the expression.

We first group and find like terms and then add and cancel out

2x²-x²- 4x+2x - 9+ 3

=x²-2x-6

Mickey did not add the coefficients -4 and +2 for x terms in the expression, instead it looked like he added 4+2 as the coefficients

Therefore the correct option is

Mickey should have added –4 and 2 when combining the coefficients of the x terms.

Using the Uniform Distribution and the Z- distribution, it is found that 1591 specimens should be tested.

Uniform Distribution: It refers to a type of probability distribution in which all outcomes are equally likely.

Z- Distribution: The standard normal distribution, also known as z distribution, is a special normal distribution where the mean is 0 and standard deviation is 01.

For an uniform distribution of bounds a & b the standard deviation is given by:  α = √ (b-a)²÷12

here, α= standard deviation.

in this problem, a = 45 and b = 750, thus the estimate is:

α = √(750-45)² ÷ 12

  = √497025 ÷ 12

  = 203.5

the margin of error of a Z confidence interval is given by:

                  M = z (α ÷√n)

where, z is the critical value

            α is the population Standard deviation

             n is the sample size.

Now, finding the critical value which is z with a p - value of (1+∝ )÷2, where ∝ is confidence level.

here, ∝ = 0.95, thus z with a p-value of (1+0.95)÷ 2 = 0.96

∴ z= 0.96

standard deviation estimates is 203.5.

now, we want sample for a margin of error of 10, then,

               M= z( α ÷ √n)

         ⇒ 10 = 1.96 ( 203.5 ÷ √n)

         ⇒ 10√n = 1.96 (203.5)

         ⇒ √n = 0.196 (203.5)

         ⇒ (√n)² = [0.196(203.5)]²

         ⇒ n = 1590.89

Round up the value 1590.89 by:

Step-by-step explanation: You can find the final equation for the segment of a circle area: A segment = A sector - A isosceles triangle = (0.5 × r² × α) - (0.5 × r² × sin(α)) = 0.5 × r² × (α – sin(α)) Formula given radius and height. A segment = r² × Arcos((r-h)/r) - (r-h) × √ (2 × r × h - h²) where h is the height of a segment, also known as sagitta.

The image point of (-9, -5) after applying this translation rule (T₋₅, ₀) and dilation (D₂) is (-28, -10).

In Mathematics, the translation of a geometric figure to the left simply means subtracting a digit from the value on the x-coordinate (x-axis) of the pre-image of a function while a geometric figure that is translated up simply means adding a digit to the value on the y-coordinate (y-axis) of the pre-image or parent function.

Mathematically, a horizontal translation to the left is modeled by this mathematical expression g(x) = f(x + N) while a vertical translation to the positive y-direction (upward) is modeled by this mathematical expression g(x) = f(x) + N.

Where:

By applying the transformation rule T₋₅, ₀ to the pre-image point (-9, -5), we have:

(x, y)                      →              (x − 5, y + 0)

(-9, -5)                   →              (-9 − 5, -5 + 0) = (-14, -5)

Next, we would apply a dilation (D₂) by using a scale factor of 2:

(x, y)        →    (kx, ky)  = (2x, 2y)

(-14, -5)    →    (2(-14), 2(-5))  = (-28, -10).

The distance at which the ladder slips down the wall is equal to 5cm.

As given in the question,

figure of the given situation attached.

Length of the ladder AD or BE = 3m

                                                  = 300cm

Distance between base of wall and ladder before slipping 'DC'= 60cm

Distance after slipping 'EC' = 80 cm

In ΔADC,

AC =√AD² -CD²

     = √ 300² - 60²

     = √86400

     = 293.9

     = 294 cm ( nearest cm)

BC = √ BE² - EC²

     = √300² -80²

    = √ 83600

    = 289.1

    = 289 cm ( nearest cm)

Distance AB = AC - BC

                     = 294 - 289

                     = 5cm

Therefore, distance between the ladder before and after slipping on the wall is 5cm.  

The complete question is :

At the start of the day , a decorator rested a 3m ladder against a vertical wall so that the foot of the ladder was 60cm away from the base of the wall.

Using the probability, if you choose two cards out of a deck of cards, then the chances one is a red face card and the other is a black non-face card is 1/2.

In the given question,

If you choose two cards out of a deck of cards, then we have to find the chances one is a red face card and the other is a black non-face card.

As we know that in a deck having 52 cards. In which 26 are red and 26 are black.

We have to choose a red face card.

As we know that in a deck have 12 face cards. In which 6 red face cards and 6 black face cards.

So the chance of getting red face card is

P(R)=Total number of red face cards/Total number of cards

P(R)=6/52

We have to choose a black non-face card.

We know that in a deck have 6 black face cards and total black cards are 26. So the non face cards are 20.

So the chance of getting black non-face card is

P(B)=Total number of black non-face cards/Total number of cards

P(B)=20/52

Now the chances of getting one is a red face card and the other is a black non-face card is

P(R or B)=P(R)+P(B)

P(R or B)=6/52+20/52

P(R or B)=(6+20)/52

P(R or B)=26/52

P(R or B)=1/2

Hence, if you choose two cards out of a deck of cards, then the chances one is a red face card and the other is a black non-face card is 1/2.

Step-by-step explanation:

Answer:

y = [tex]\frac{5}{3}[/tex] x -9

Step-by-step explanation:

Put both equations in the slope intercept form

y =mx + b

5x - 3y = 7  Subtract 5x from both sides

-3y = -5x + 7  Divide both sides by -3

y = [tex]\frac{-5}{-3}[/tex] x + [tex]\frac{7}{-3}[/tex]  Cleaned up

y = [tex]\frac{5}{3}[/tex] x - [tex]\frac{7}{3}[/tex]

4x -y = 9  Subtract 4x from both sides

-y = -4x + 9  Divide all the way through by -1

y = 4x - 9

To make a line parallel to the first equation, we need the same slope.  The slope of the first equation is [tex]\frac{5}{3}[/tex].  We are also told to have the same y intercept as the second equation which is -9

y = [tex]\frac{5}{3}[/tex] x  - 9

Value for multiplication of 6.75 x 10⁶ and 1.2 × 10⁶ : 8.1 x 10¹²

What is Multiplication?

The process of finding the sum of two or more numbers is known as multiplication. It is a fundamental operation in mathematics that is frequently utilized in everyday life. When we need to combine groups of the same size, we employ multiplication.

The fundamental concept of repeatedly adding the same number is represented by the process of multiplication. The results of multiplying two or more numbers are known as the product of those numbers, and the factors that are multiplied are referred to as the factors. Repeated addition of the same number is made easier by multiplying the numbers.

We have the given values to multiply:

6.75 x 10⁶ and 1.2 × 10⁶

Now,

= 6.75 x 10⁶ x 1.2 × 10⁶

= (6.75 x 1.2) x (10⁶ x 10⁶)

= (8.1) x 10⁽⁶⁺⁶⁾

= 8.1 x 10¹²
