Answer:

The vertex is [3,0]

Step-by-step explanation:

y=a(x−h)2+k , where ( h,k ) is the vertex of the parabola. By comparing the two equations, we see that h=3 and k=0 . The vertex is at ( 3,0 ).

If the area is 64 inches squared, what is the missing length ?

Igoryamba

The area of a parallelogram is equal to the base multiplied by the height. Since we can see that this is a parallelogram (because of the two pairs of parallel sides), we now know how to find the area. Since we already know the height and the area, we can substitute their values into the formula to solve for the base.

8 * (the base) = 64

Divide each side by 8 to figure out the length of the base

the base = 8 in.

In a true-false test containing 50 questions, a student is to be awarded 2 marks for every correct answer and -2 for every incor

BlackZzzverrR [31]

Answer:

1. 47 correct, 0 wrong and 3 unanswered

2. 48 correct, 1 wrong and 1 unanswered

Step-by-step explanation:

Given;

Total number of questions = 50

For correct answers = 2

For wrong answers = -2

Unanswered questions = 0

Yash scored 94 marks

Let c, w and u represent the number of correct, wrong and unanswered questions

2×c - 2 × w + 0×u = 94

2c -2w = 94 .....1

And;

c + w + u = 50 .....2

We have 2 equations and 3 unknowns

By observing the problem, we can see two possible solutions;

Case 1: Assuming he did not miss (get wrong) any answer;

He needs to score 47 answers right;

47 × 2 = 94

Then;

c = 47 w = 0 and u = 50 - (47+0) = 3

47 correct, 0 wrong and 3 unanswered

Case 2: Assuming he got one answer wrong;

He would need to score one more answer right compared to the first case;

(47+1) × 2 - 1 × 2 = 96 - 2 = 94

c = 47+1 = 48

w = 1

u = 50 - (48+1) = 1

So he need to score 48 correct answers, 1 wrong answer and 1 unanswered.

Alison has all her money invested in two mutual funds, A and B. She knows that there is a 40% chance that fund A will rise in pr

alisha [4.7K]

Answer:

24% probability that both fund A and fund B will rise in price

Step-by-step explanation:

We have these following probabilities:

40% probability that fund A will rise in price.

If fund B rises in price, 60% probability that fund B does.

What is the probability that both fund A and fund B will rise in price

40% of A, and if A rises, 60% is B. Since the only outcome that interests us is both rising in price, we multiply these probabilities

$P = 0.4*0.6 = 0.24$

24% probability that both fund A and fund B will rise in price
