1/4 of the cupcakes are chocolate.
1/8 of the cupcakes are strawberry.
The remainder of the cupcakes are vanilla.

How many of the cupcakes are vanilla?

Answer:

8x+5005073

Step-by-step explanation:

The function f(x) = 5x^2 + 20x + 25 can be rewritten in vertex form as f(x) = 5(x + 2)^2 + 5, and its vertex is located at (-2, 5).

To rewrite the function f(x) = 5x^2 + 20x + 25 in vertex form, we complete the square. The vertex form of a quadratic function is given by f(x) = a(x - h)^2 + k, where (h, k) represents the vertex.

Let's complete the square:

f(x) = 5(x^2 + 4x) + 25

To complete the square, we need to add and subtract (4/2)^2 = 4 to the expression inside the parentheses:

f(x) = 5(x^2 + 4x + 4 - 4) + 25

Rearranging the terms:

f(x) = 5((x^2 + 4x + 4) - 4) + 25

Now we can factor the perfect square inside the parentheses:

f(x) = 5((x + 2)^2 - 4) + 25

Expanding and simplifying further:

f(x) = 5(x + 2)^2 - 20 + 25

f(x) = 5(x + 2)^2 + 5

Therefore, the function f(x) = 5x^2 + 20x + 25 in vertex form is f(x) = 5(x + 2)^2 + 5. The vertex is given by the coordinates (-2, 5).

The correct question should be :

What is the vertex form of the function f(x) = 5x^2 + 20x + 25? Identify the coordinates of the vertex.

Answer:

∠ W = 51°

Step-by-step explanation:

Since WX is the diameter , then

∠ WYX = 90° ( angle in a semicircle )

The sum of the 3 angles in a triangle = 180° , then

x + x + 12 + 90 = 180

2x + 102 = 180 ( subtract 102 from both sides )

2x = 78 ( divide both sides by 2 )

x = 39

Then

∠ W = x + 12 = 39 + 12 = 51°

Step-by-step explanation:

As the required line is perpendicular to y = (1/2)x + 5, product of slope of y = (1/2)x + 5 and required line should be - 1.

=> (1/2)m = - 1

=> m = - 2

Thus, required line is

=> y - (-8) = (-2)(x - 3)

=> y + 8 = -2(x - 3)

P(A) = 6/36 = 1/6, P(B) = 21/36 = 7/12, P(A|B) = P(A∩B) / P(B) = 6/36 / 21/36 = 6/21 = 2/7.  The outcomes in both A and B are: {(1,1), (2,2), (3,3), (4,4), (5,5), (6,6)}. The number of outcomes in A and B = 6.

4.1 Sample Space and Events in Set Notation:

When a blue and red die are thrown simultaneously, the sample space, denoted by S, consists of all possible outcomes. Since each die has six faces numbered 1 to 6, there are 36 possible outcomes in total.

Sample Space (S): {(1,1), (1,2), (1,3), (1,4), (1,5), (1,6), (2,1), (2,2), (2,3), (2,4), (2,5), (2,6), (3,1), (3,2), (3,3), (3,4), (3,5), (3,6), (4,1), (4,2), (4,3), (4,4), (4,5), (4,6), (5,1), (5,2), (5,3), (5,4), (5,5), (5,6), (6,1), (6,2), (6,3), (6,4), (6,5), (6,6)}

Event A represents the outcomes where the values on both dice are the same:

A = {(1,1), (2,2), (3,3), (4,4), (5,5), (6,6)}

Event B represents the outcomes where the value on the red die is greater than or equal to the value on the blue die:

B = {(1,1), (1,2), (1,3), (1,4), (1,5), (1,6), (2,2), (2,3), (2,4), (2,5), (2,6), (3,3), (3,4), (3,5), (3,6), (4,4), (4,5), (4,6), (5,5), (5,6), (6,6)}

4.2 Calculating Probabilities:

P(A): To find the probability of event A, we divide the number of favorable outcomes (6) by the total number of outcomes (36).

P(A) = 6/36 = 1/6

P(B): To find the probability of event B, we divide the number of favorable outcomes (21) by the total number of outcomes (36).

P(B) = 21/36 = 7/12

P(A|B): To find the conditional probability of event A given event B, we need to find the probability of A and B occurring together and divide it by the probability of event B.

The outcomes in both A and B are: {(1,1), (2,2), (3,3), (4,4), (5,5), (6,6)}

The number of outcomes in A and B = 6.

P(A|B) = P(A∩B) / P(B) = 6/36 / 21/36 = 6/21 = 2/7

Step-by-step explanation:

20% of 17= 3.4

Add it to the initial $17 and you get $20.4

Answer: $20.40

Step-by-step explanation:

Since you're giving a 20% tip, your total will be 120% the price of the shampoo and cut.

17 * 120%

= 17 * 1.2

= 20.4

The predicted value of y when x = 15 is given as follows:

15.8.

To find the regression equation, which is also called called line of best fit or least squares regression equation, we need to insert the points (x,y) in the calculator.

The points in this problem are given as follows:

(12, 18), (9, 35), (14, 12), (8, 40), (10, 31), (4, 33), (18,10).

Inserting these points into the calculator, the line of best fit is given as follows:

y = -2.28x + 50.

When the value of y when x = 15 is given as follows:

y = -2.28(15) + 50

y = 15.8.
