1 answer:
sasho [114]3 years ago
3 0

Answer:

Part 1) {0,1,2,3,4}

Part 2) {February, April, June,September, November}

Part 3) {L, M, N, P, Q, R, S, T, V, W,X,Y, Z}

Step-by-step explanation:

Part 1) List the elements of the set

x is an integer for the interval (-1/2,9/2)

Remember that

-1/2=-0.5

9/2=4.5

so

we know that

The integers in the given interval are

(-0.5,4.5)

therefore

The elements of the set are

{0,1,2,3,4}

Part 2) List the elements of the set

x is an month of the year which does not contain 31 days

The months which not contains 31 days are

February, April, June,September, November

therefore

The elements of the set are

{February, April, June,September, November}

Part 3) List the elements of the set

x is a consonant of English alphabet which comes before k

we know that

The 21 consonant letters in the English alphabet are

B, C, D, F, G, H, J, K, L, M, N, P, Q, R, S, T, V, W,X,Y, Z

so

The consonant of English alphabet which comes before k are

L, M, N, P, Q, R, S, T, V, W,X,Y, Z

therefore

The elements of the set are

{L, M, N, P, Q, R, S, T, V, W,X,Y, Z}

When you translate, (x, y+6) will move
Darya [45]

Answer:

(x, y+6) will vertically move 6 units up.

Step-by-step explanation:

If we move vertically 6 units up, 6 is added to the y-coordinate.

so

(x, y+6) will vertically move 6 units up.

For example, let suppose the point P(-2, 3). When we apply a translation of (x, y+6) to the point P(-2, 3), the coordinates of point P after the translation will be:

(x, y)              →                 (x, y+6)

P(-2, 3)          →                 P(-2, 9)             ∵ P(-2, 3+6)

Therefore, (x, y+6) will vertically move 6 units up.

natalie guessed on the last four true or false questions on her math quiz. what is the probability that she got all four quiz qu
Verizon [17]
Each question is either true or false, so the sample space is 2, true and false, two states only.

what's the probability she got one correct, well, the favorable outcomes is 1, possible outcomes is 2, so 1/2.

what's the probability that she got all four correct, we simply multiply the probability of each,


\bf \cfrac{1}{2}\cdot \cfrac{1}{2}\cdot \cfrac{1}{2}\cdot \cfrac{1}{2}\implies \cfrac{1}{16}\implies 0.0625\qquad or\qquad 6.25\%

An airline estimates that 94% of people booked on their flights actually show up. If the airline books 68 people on a flight for
Setler79 [48]

Answer:

0.0788

Step-by-step explanation:

In this case the final probability will be the sum of the probability of when there are 67 more reserves when there are 68.

That is to say:

P (f) = P (x = 67) + P (x = 68)

n = 68; p = 0.94

Now we calculate each one:

P (x) = nCx * (p ^ x) * [(1 - p) ^ (n-x)]

nCx = n! / (x! * (n - x)!)

Knowing the formula, we replace:

P (67) = 68C67 * (0.94 ^ 67) * [(1 - 0.94) ^ (68-67)]

nCx = 68! / (67! * (68 - 67)!) = 68! / 67! = 68

P (67) = 68 * (0.0158) * (0.06) = 0.064

Now for x = 68

P (68) = 68C68 * (0.94 ^ 68) * [(0.0641 - 0.94) ^ (68-68)]

nCx = 68! / (68! * (68 - 68)!) = 1

P (68) = 1 * (0.0148) * (1) = 0.0148

Then replacing in the main formula:

P (f) = P (x = 67) + P (x = 68)

P (f) = 0.064 + 0.0148

P (f) = 0.0788
