Jackie is practicing free throws after basketball practice. She makes a free throw shot with probability 0.7. She takes 20 shots
Sergeu [11.5K]

Answer:

n = 20 q = 0.7, q = 0.3

Step-by-step explanation:

For each shot that she takes, there are only two possible outcomes. Either she makes or, she does not make is. The probability of making each shot is independent from other shots. So we use the binomial probability distribution to solve this problem.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

In which C_{n,x} is the number of different combinations of x objects from a set of n elements, given by the following formula.

C_{n,x} = \frac{n!}{x!(n-x)!}

And p is the probability of X happening.

We also ahve that q = 1-p.

Jackie is practicing free throws after basketball practice. She makes a free throw shot with probability 0.7.

This means that p = 0.7 and q = 1-p = 0.3

She takes 20 shots.

This means that n = 20

So the correct answer is:

n = 20 q = 0.7, q = 0.3

Hooke's Law. The distance d when a spring is stretched by a hanging object varies directly as the weight w of the object. If the
algol [13]

The distance is 52.5 cm when weight is 7kg

Step-by-step explanation:

Distance is 15 cm when weight is 2 kg

We need to find the distance d when weight is 7 kg

Since distance and weight varies directly so,

\frac{15}{2}=\frac{d}{7}

Solving the above expression:

\frac{15}{2}=\frac{d}{7}\\Cross\,\,multiply\\15*7=d*2\\105=d*2\\d=\frac{105}{2}\\d=52.5

So, The distance is 52.5 cm when weight is 7kg

Can you guys help me find the area of this shape. I've literally tried everything and got it wrong.
Ghella [55]

Answer:

110 square centimeters.

Step-by-step explanation:

The area for a trapezoid can be figured out with the equation (a + b)h/2.

(9 * 5) + (9 + 4)10/2 <em>{Work inside the parentheses first.}</em>

45 + (13)10/2 <em>{Divide 10 by 2 to get 5.}</em>

45 + 13(5) <em>{Multiply 13 by 5 to get 65.}</em>

45 + 65 <em>{Add 45 & 65 to get 110.}</em>

110 square centimeters.

The area of the figure is 110 square centimeters.
