Josh used a standard deck of 52 cards to conduct an experiment. Half of the cards in the deck were red. The other half were black. Josh predicted that he would choose a red card in 4 out of 8 trials. When he conducted the experiment, he actually chose a red card 6 out of 8 times. Which explains the most likely reason for the discrepancy between Josh’s predicted and actual results?He incorrectly predicted the number of times he would choose a red card. He incorrectly determined the actual number of times he chose a red card. He used too few trials for the sample space. He used too many trials for the sample space.

Answer A

Is it right The question
The function f(t) = t2 + 4t − 14 represents a parabola.

Part A: Rewrite the function in vertex form by completing the square. Show your work. (6 points)

Part B: Determine the vertex and indicate whether it is a maximum or a minimum on the graph. How do you know? (2 points)

Part C: Determine the axis of symmetry for f(t). (2 points)

Answers

f(t) = t2 + 4t − 14

y + 14 + 4 = ( t2 + 4t +4)

y + 18 = ( t + 2)^2

so the vertex of the parabola is ( -2 , -18)

the axis of symmetry is y = -18

Choose the correct mixed number for the quotient. 38 ÷ 5 = 7 R3

A)7 5/3

B)7 3/38

C)9 4/85

D)7 3/5

Answers

That would be D. 7 3/5 because 7 is the answer but 3 isn't greater than 5 so it cant make a whole so it makes a fraction of 7 3/5.

Bryan purchased two triangular wall shelves. The sides of each shelf are 8 inches, 10 inches, and 12 inches. He's trying to build a similar, larger triangular shelf to hang between the smaller ones. Which of the dimensions can Bryan use for the larger shelf so that it is similar to the ones he purchased? Justify why the three triangles are similar.A) 4 inches, 5 inches, and 6 inches; All of the side lengths of the smaller triangles have been multiplied by 1/2 which guarantees side-side-side similarity
.
B) 16 inches, 20 inches, and 24 inches; All of the side lengths of the smaller triangles have been multiplied by 2, which guarantees side-side-side similarity.
C) 16 inches, 20 inches, and 24 inches; All of the side lengths of the smaller triangles have been multiplied by 2, which guarantees side-angle-side similarity.
D) 16 inches, 20 inches, and 24 inches; All of the side lengths of the smaller triangles have been multiplied by 2, which guarantees angle-angle-side similarity.

Answers

The correct answer is letter B) 16 inches, 20 inches, and 24 inches; All of the side lengths of the smaller triangles have been multiplied by 2, which guarantees side-side-side similarity. Similar angles shows congruence when their sides are proportional.

Answer:

(B) 16 inches, 20 inches, 24 inches; All the side lengths of the smaller triangles have been multiplied by 2, which guarantees side-side-side similarity.

Step-by-step explanation:

The sides of the triangular wall shelves are given as 8 inches, 10 inches and 12 inches. In order to build a larger, similar triangle he must multiply the sides of the triangle wall by 2 so that it follows the similarity conditions,that is:

$(16)/(8) =(20)/(10)=(24)/(12) =(2)/(1)$

Since, we were given the sides of the triangular wall shelves, therefore the new triangle formed will also be formed of three sides.

Hence, Option (B) is correct in which all the sides of smaller triangles are multiplied by 2 which guarantees side-side-side similarity.
