Which step is the most efficient way to find the solution of p+5>−13?

The probability of choosing the red card will be 0.03%

In this situation, Mickey should have drawn the first 7 cards that are not diamond and then on the 8th attempt she should draw an ace.

Let A be the event of drawing 7 cards which are not diamond and B the event of drawing an ace card. therefore the required probability is

P(A∩B)=P(A)*P(B)

Now, there are 13 diamonds and 39 other cards. Hence,

P(A)=(13/39)⁷=0.1335

After drawing 7 non-diamond cards, the 8th card must be a diamond. Hence,

P(B)=0.25

Hence, P(A∩B)=P(A)*P(B)=0.1335*0.25=0.033(approximately 0.03,i.e. 3%)

Therefore the probability that Mickey will draw her first red diamond on the 8th attempt is 0.03%

Percy solved the equation by expanding the expression on the left-hand side, and this is incorrect

The equation is given as:

x^2 + 7x + 12 = 12

The first step in solving the equation is to equate the equation to 0.

i.e.

x^2 + 7x + 12 - 12 = 0

This given

Answer:

Percy is not correct because he applied the zero product property to a factored expression that was not equal to 0. He should have subtracted 12 from both sides to get x2 + 7x = 0 before factoring. The correct solutions are 0 and -7.

In a quadrilateral ABCD, the measure of the length of the quadrilateral CD will be 25.98 cm.

The connection between the lengths and angles of a triangular shape is the subject of trigonometry.

The length of AD will be

tan θ = AB/AD

AD = 12/ tan 35

AD = 17.14 cm

Then the value of the BD will be given by the Pythagoras.

BD² = AB² + AD²

BD² = 12² + 17.14²

BD² = 144 + 239.78

BD² = 437.78

BD = 20.92 cm

Then operate the sine rule in triangle BCD, we have

[tex]\dfrac{BD}{\sin C} = \dfrac{CD }{\sin B}\\\\\\\dfrac{20.92}{\sin 52} = \dfrac{CD }{\sin 102}\\\\\\CD = \dfrac{20.92 \times \sin 102}{\sin 52}[/tex]

On further solving, the value of CD will be

Since vertically opposite angles are equal, y° = 60°.

[tex]\rule[225]{225}{2}[/tex]

Answer:

Vertical angles

Step-by-step explanation:

The 60° angle and the angle marked y° are vertical angles. Vertical angles are equal. They are formed by two lines crossing (intersecting lines) I like to think of them like a pair of scissors, opening and closing! The angles get bigger or smaller together. The angle marked x° and the unmarked angle are another pair of vertical angles.

Q2 is the median

Answer:

x=21

Step-by-step explanation:

For simplicity's sake, I started by naming the angles. Please reference the attachment.

For this, we're using parallel lines with one intersecting line (transversal) to give us valuable information about the angles.

First, based on the Corresponding Angles Theorem, corresponding angles, such as A and B, are congruent.

This means that angle B can also be represented by the expression 6x-19.

Furthermore, since angles B and C are on the same line, they must be supplementary, meaning that they add up to 180 degrees.

This said, we can set up an equation to solve for x because B+C=180

6x-19+3x+10=180

Combine Variables

9x+10-19=180

9x-9=180

Add 9 to both sides to isolate x

9x=189

Divide both sides by 9

x=21

This problem could have also been solved with various other theorems such as, but not limited to:

Keep in mind a prerequisite for all of these theorems except the vertical angles theorem are that it must be for a transversal cutting/intersecting 2 parallel lines.

The Alternate Exterior Angles Theorem states that alternate exterior angles are congruent (A and D)

The Alternate Interior Angles Theorem states that alternate interior angles are congruent (C and E)

The Vertical Angles Theorem states the vertical angles- angles across from each other- are congruent (B and D)

The Same Side Exterior Angle Theorem states that same side exterior angles supplementary (A and F)

The Same Side Interior Angle Theorem states that same side interior angles are supplementary (E and B)

The distance between a and b is 5 units.

An equilateral triangle has three sides that have the same length. The triangle is defined as the plane two-dimensional figure with three sides having the sum of the three angles of 180 degrees.

Since the figure is missing in the question so I have attached the figure of the points on the graph for better understanding.

The given coordinates are as follows:-

a (-3, 2)

b (-6, -2)

c (0, -2)

Use the distance formula,[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex] , to find ab.

ab  = √[(−6−(−3))² + (−2−2)²]

ab  = √25

ab  = 5 units

Therefore the distance between A and B is 5 units.

Step-by-step explanation:

Total tuition for the full four years = 11,800 + 11,900 + 12,000 + 12,100 = 47,800

Total money from scholarship = 1,500 × 4 = 6,000

Total income received = 2,500 × 4 = 10,000

Total money to borrow = 47,800 - 6,000 - 10,000 = 31,800

The cost of each bag of soil is $ 16.25 and the cost of each bag of fertilizer is $ 12.99.

A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.

Mr. Ellis has started a vegetable garden.

He bought 15 bags of soil and 3 bags of fertilizer for 282.72.

He realized he did not have enough supplies so he bought another 5 bags of soil and 2 bags of fertilizer for 107.23.

Let the cost of each bag of soil be x and the cost of a bag of fertilizer be y.

Then we have the linear equations,

15x + 3y = 282.72

5x + 2y = 107.23

On solving the equations 1 and 2, we have

x = 16.25 and y = 12.99

The cost of each bag of soil is $ 16.25 and the cost of each bag of fertilizer is $ 12.99.

Step-by-step explanation:

Sum of all angles of triangle = 180

    104 +52 +  ∠Z = 180

            156 + ∠Z = 180

                      ∠Z = 180 - 156

                      Z = 24

The sides opposite to the biggest is the longest side.

Angles in descending order: ∠X  >  ∠Y >  ∠Z

Find another angle

The best estimate of the profit when 350 pounds of food are produced is $5300

The quadratic regression is given as:

[tex]f(x) = -0.0817x^2 + 102.24x - 20421[/tex]

When 350 pounds are produced, it means that:

x = 350.

So, we have:

f(350) = -0.0817(350)^2 + 102.24(350) - 20421

Evaluate

f(350) = 5354.75
