What is the probabilty of drawing a diamond from a standard deck of cards on a second draw, give that a diamond was drawn on the first draw and not replaced?

12/51
1/52
1/52
13/52

Answers

Answer 1
Answer:  12/51 (choice A)

===========================================================

Explanation:

"Given that a diamond was drawn on the first draw and not replaced" means we know 100% that there are P = 13 - 1 = 12 diamonds left out of Q = 52-1 = 51 cards overall.

The probability of picking another diamond card is therefore P/Q = 12/51

This only works if the card is not replaced. If the card is replaced, then the probability would be 13/52 = 1/4.

Jaden is comparing two cones. The radius of the base of cone AA is twice as large as the radius of the base of cone BB. The height of cone BB is twice the height of cone AA. The volume of cone AA is

Answers

Answer:

VA = 2/3πrB²hB

Step-by-step explanation:

Let the volume of cosA ad cone B be expressed as;

Va = 1/3πra²ha

Vb = 1/3πrb²hb

If the radius of the base of cone A is twice as large as the radius of the base of cone B

rA = 2rB

If the height of cone B is twice the height of cone A, then;

hB = 2hA

hA = hB/2

Recall that;

VA = 1/3πrA²hA

VA = 1/3π(2rB)²(hB/2)

VA = 1/3π*4rB²(hB/2)

VA = 2/3πrB²hB

This gives the volume of cone A

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

The number of pairs of pants = 2 pairs

The number of pairs of t-shirts = 8 pairs

The number of pairs of shoes = 2 pairs

And , the total number of outcomes A = 2 x 8 x 2

On simplifying the equation , we get

The different outfits does Joseph can choose A = 32 outfits

Hence , the equation is A = 32 outfits

find the coordinates of the intersection of the diagonals of parallelogram PQRS with vertical P(-5,5) Q(2,5) , R(4,-3) and S(-3,-3)

Answers

Given:

The vertices of parallelogram PQRS are P(-5,5) Q(2,5) , R(4,-3) and S(-3,-3).

To find:

The intersection of the diagonals of parallelogram PQRS.

Solution:

We know that the diagonals of a parallelogram bisect each other.

In parallelogram PQRS, PR and QS are the diagonals of the parallelogram.

It means the intersection of PR and QS is the midpoint of PR and QS.

Midpoint formula:

[tex]Midpoint=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)[/tex]

Midpoint of diagonal PR is:

[tex]Midpoint=\left(\dfrac{(-5)+4}{2},\dfrac{5+(-3)}{2}\right)[/tex]

[tex]Midpoint=\left(\dfrac{-1}{2},\dfrac{2}{2}\right)[/tex]

[tex]Midpoint=\left(-0.5,1\right)[/tex]

Therefore, the coordinates of the intersection of the diagonals of parallelogram PQRS are (-0.5,1).

in basketball, steph curry is a 90.31% free throw shooter. IN a random game, he attempted 12 free throws. What is the probability that he made at least10 out of the free throws

Answers

Answer:

0.8969

Step-by-step explanation:

This can be solved using the binomial probability relation :

P(x = x) = nCx * p^x * q^(n-x)

p = 0.9031

Number of trials, n = 12

q = 1 - p =0.0969

x ≥ 10

P(x ≥ 10) = P(x= 10) + p(x = 11) + p(x = 12)

P(x = 10) = 12C10*0.9031^10 * 0.0969^2 = 0.2236

P(x = 11) = 12C11 * 0.9031^11 * 0.0969^1 = 0.3790

P(x = 12) = 12C12*0.9031^12 * 0.0969^0 = 0.2943

P(x ≥ 10) = (0.2236 + 0.3790 + 0.2943)

P(x ≥ 10) = 0.8969

The ratio of the length of the toucan’s bill to the length of its body is 1 inch to 3.5 inches. If the bill is 7 inches, how long is the body?

Answers

Answer:

24.5 inches

Step-by-step explanation:

The ratio of the length of the toucan’s bill to the length of its body can be expressed as

(1: 3.5)

Then if the bill is 7 inches, then the Length of the body will be X

1: 3.5

7: X

If we cross multiply, we have

X= 7×3.5

X= 24.5

Hence, the Length of the body is 24.5 inches

A company that makes robotic vacuums claims their newest model of vacuum lasts, on average, two hours when starting on a full charge. To investigate this claim, a consumer group purchases a random sample of five vacuums of this model. They charge each unit fully and then measure the amount of time each unit runs. Here are the data (in hours): 2.2, 1.85, 2.15, 1.95, and 1.90. They would like to know if the data provide convincing evidence that the true mean run time differs from two hours. What are the appropriate hypotheses?

H0: μ = 2 versus Ha: μ < 2, where μ = the true mean run time for all vacuums of this model
H0: μ = 2 versus Ha: μ > 2, where μ = the true mean run time for all vacuums of this model
H0: μ = 2 versus Ha: μ ≠ 2, where μ = the true mean run time for all vacuums of this model
H0: μ ≠ 2 versus Ha: μ = 2, where μ = the true mean run time for all vacuums of this model

Drag the green point on the tape diagram to model a discount of 27%.

If the discount is 27%, then what percent of the original price do you pay?

Answers

Answer:

73%

Step-by-step explanation:

Let us have the original price as $100

A discount of 27% will be;

27/100 * 100 = $27

so, the value to be paid will be $100 - $27 = $73

Now, what percentage of $100 is the $73 that was paid

that would be;

73/100 * 100% = 73%
