Answer:

Choice C is correct answer.

Step-by-step explanation:

We have given a vertex of a equation.

vertex = (-1,5)

We have to find the quadratic in vertex form.

The equation in vertex form is:

y = (x-h)²+k where (h,k) is vertex.

Putting given values in above formula, we have

y =  (x-(-1))²+(5)

y =  (x+1)²+5 which is equation in vertex form that has a vertex of (-1,5).

Answer:

Third option

y = (x+1) ^ 2 + 5

Step-by-step explanation:

In this case we must write a quadratic equation in the vertex form.

We have the vertice. (-1, 5)

We know that the vertex form for a quadratic equation is:

y = (x-h) ^ 2 + k.

Where (h, k) is the vertex.

So if the vertex is (-1, 5), the equation sought is:

y = (x-(-1)) ^ 2 + 5

y = (x+1)) ^ 2 + 5

Therefore the answer is the Third option.

Among 21- to 25-year-olds, 29% say they have driven while under the influence of alcohol. Suppose that three 21- to 25-year-olds
Sophie [7]

Answer:

P(3) = 0.0244

P(3) = 2.44%

the probability that all three selected have driven while under the influence of alcohol is 2.44% or 0.0244

Step-by-step explanation:

Given;

The probability that they have driven while under the influence of alcohol is;

P = 29% = 0.29

the probability that all three selected have driven while under the influence of alcohol is;

P(3) = P × P × P

P(3) = 0.29 × 0.29 × 0.29

P(3) = 0.024389

P(3) = 0.0244

P(3) = 2.44%

the probability that all three selected have driven while under the influence of alcohol is 2.44% or 0.0244

How to solve this brainteaser
laila [671]

Answer:

last row equals 333

Step-by-step explanation:

The clock showing time 9:00 should be worth 9 points, and the clock showing 3:00 should be worth 3 points, giving for the first row:

9 + 9 + 3 = 21

the three equal calculators showing 1234 are worth 10 points each:

1+2+3+4 = 10

and 10 + 10 + 10 = 30

the light bulbs should be 15 points each then giving 15 + 15 - 15 = 130 - 15 = 15 Notice also that they all have 5 rays of light coming out (so a 3 points per ray)

Now for the bottom line we have:

9 + (1+2+2+4) times 3 * 12 (only four rays on each bulb thus 4 * 3 = 12)

Notice we added the figures that appear in the calculator.

9 + 9 * 36 = 333
