Options are;

A) the Normal distribution, with mean 2 and variance 1

B) the binomial distribution, with parameters n = 4 and p = 0.5

C) the poisson distribution, with parameters λ = 4/10

D) none of the above

Answer:

B) the binomial distribution, with parameters n = 4 and p = 0.5

Step-by-step explanation:

Number of times card is shuffled is 4 times. Thus; n = 4

X is the number of cards in the time shuffled that corresponds to a male.

We are told there are 10 students and 5 are male and 5 female.

Thus, probability that it corresponds to a male is;

P(corresponding to a male) = 5/10 = 0.5

According to binomial probability distribution, the parameters are;

p = 0.5

n = 4

q = 1 - 0.5 = 0.5

Answer:

c. Substitute

Step-by-step explanation:

A graph of the function on the left shows the parabola touches the x-axis at x = -8/3. That is, the vertex is on the x-axis. It crosses the y-axis at y = 64.

<h3>Show a value is a root</h3>

A given solution to an equation can be verified by substituting that value into the equation an showing the result is a <em>true statement</em>. Here, the value x=-8/3 is a root of the given equation because that value makes the equation true.

$9\left(-\dfrac{8}{3}\right)^2+48\left(-\dfrac{8}{3}\right)+64=0\\\\9\left(\dfrac{64}{9}\right)-\left(\dfrac{48\cdot8}{3}\right)+64=0\\\\64-\dfrac{3\cdot2\cdot8\cdot8}{3}+64=0\\\\64-2\cdot64+64=0\\\\0=0\qquad\text{True}$

Help me pls i’ll give you a kiss

Likurg_2 [28]

Answer: 152.46 squared centimeters.

Step-by-step explanation:

The equation to find the area of the trapezoid is A = ½ (6.6 + 16.5) 13.2
Distribute ½ into (6.6 + 16.5) . A = (3.3 + 8.25) 13.2.
Add the numbers inside the parenthesis. A = 11.55 * 13.2
Multiply 11.55 * 13.2. A = 152.46.

If BH = 3, BF = 10, GH = 2, find HD

s344n2d4d5 [400]

Answer:

HD = 10.5

Step-by-step explanation:

Given BH = 3, GH = 2, BF = 10

Step 1: To find HF:

HF = BF – BH

HF = 10 – 3

HF = 7

Step 2: To find HD:

We know that if two chords intersects inside a circle, the product of the lengths of the segments of one chord equals the product of the lengths of the segments of the other chord.

⇒ GH × HD = BH × HF

⇒ 2 × HD = 3 × 7

⇒ HD = 10.5

Hence, the value of HD = 10.5.

I hope this helps a little bit.

The inequalities is given by x + y ≤ 120, 4.75x + 7.5y > 690 and y ≥ 80. A possible solution is selling 10 tacos and 100 burritos

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more numbers and variables.

Independent variables represent function inputs that do not depend on other values, while dependent variables represent function outputs that depends on other values.

Let x represent the number of tacos and y represent the number of burritos sold, hence:

x + y ≤ 120 (1)

Also:

4.75x + 7.5y > 690 (2)

and:

y ≥ 80 (3)

The inequalities is given by x + y ≤ 120, 4.75x + 7.5y > 690 and y ≥ 80. A possible solution is selling 10 tacos and 100 burritos
