Think about Digit's game of spinning the spinner.
He wants to know the probability of the following events happening on two separate spins.
A: spinning praline wafer
B: spinning oven-baked apple & lavender calzone
Which formula should Digit use to find the probability?
P(A∩B)=P(A)⋅P(B|A)
P(A∪B)=P(A)+P(B)
P(A∪B)=P(A)+P(B)−P(A∩B)
P(A∩B)=P(A)⋅P(B)
Answer:
Should be P(A∩B)=P(A)⋅P(B)

4. Which pair of trig functions are equivalent?
sin 23, sin 67
COS 41, sin 41
cos 58, sin 122
cos 76, sin 14
The pair of trigonometric functions that are equivalent is cos76°, sin14°.
What are trigonometric ratios in terms of a right-angle triangle?We know a right-angled triangle has three sides they are -: Hypotenuse,
Opposite and Adjacent.
We can remember SOH CAH TOA which is,
sin = opposite/hypotenuse, cos = adjecen/hypotenuse and
tan = opposite/adjacent.
We know sin(π/2 - Ф) = cosФ and cos(π/2 - Ф) = sinФ.
sin23° = cos(90° - 23°) = cos67°.
cos41° ≠ sin41°.
cos58° = cos(180° - 58°) = cos122°.
cos76° = sin(90° - 76°) = sin14°.

At the grocery store, sliced turkey deli meat is on sale for $11 for 2 pounds. a. What is the cost per pound of sliced turkey deli meat? b. Write an equation to represent the cost "y" of sliced turkey deli meat measured in "x" pounds. *
Answer:
- $5.5 per pound
- [tex]y = 5.5x[/tex]
Step-by-step explanation:
Given
$11 for 2 pounds
Solving (a): Cost per pound
This is calculated by dividing $11 by 2 pounds
[tex]Cost\ per\ pound = \frac{\$11}{2\ lb}[/tex]
[tex]Cost\ per\ pound = \$5.5/\ lb[/tex]
Hence, the cost per pound is $5.5 per pound
Solving (b): Represent as an equation.
If 1 pound costs $5.5 (as shown in (a))
Then
x pounds costs $5.5 * x
[tex]Cost = 5.5 * x[/tex]
[tex]Cost = 5.5x[/tex]
This cost is represented with y
[tex]y = 5.5x[/tex]

Dave ran from one corner of a field to the opposite corner , a distance of 100 meters . Then he ran along its length, a distance of 96 meters . How wide is the field
Answer:
28 meters wide
Step-by-step explanation:
This involves using the Pythagorean Theorem.
We know: a (the length)=96, b (the width)=?, c (diagonal distance)=100
a^2+b^2=c^2
96^2+b^2=100^2
9216+b^2=10000
b^2=784
b=28
The field is 28 meters wide

Step-by-step explanation:
The segment AC is the angle bisector of angle BAD and angle BCD.
What is an angle bisector?A ray, segment, or line that divides a given angle into two equal angles is known as an angle bisector.
When something is bisected or bisected, it is split into two equal sections. In geometry, an angle bisector is a line or ray that divides a triangle into two equal angles.
here, we have,
Given that ΔABC ≅ ΔADC Prove: AC bisects ∠BAD and AC bisects ∠BCD
From the given data it is concluded that all the corresponding angles of the triangle are equal to each other.
In the triangle ABC and ADC:-
∠BAC = ∠DAC
∠BCA = ∠DCA
From the above proof, it is concluded that the AC bisects ∠BAD and ∠BCD.
Therefore, the segment AC is the angle bisector of angle BAD and angle BCD.
