A basketball player has made 70% of his foul shots during the season. Assuming the shots are independent, find the probability

bija089 [108]

Answer:

a) 0.07203

b) 0.0189

c) 0.973

Step-by-step explanation:

Probability of making one shot, for the player = 70% = 0.70

Probability of NOT making a shot = 1 - 0.70 = 0.30

Assuming that the shots are independent

a) Misses for the first time on his fifth attempt

For him to miss on his for the first time on his fifth attempt, he has to make the first four shots

The required probability = (0.7)⁴(0.3) = 0.07203

b) Makes his first basket on his fourth shot

For him to make his first basket on the fourth shot, he has to miss the first three shots.

Required probability = (0.3)³(0.7) = 0.0189

c) Makes his first basket on one of his first 3 shots

This is a sum of probabilities; that is, he could make the first basket on the first shot, or miss on the first shot and make the second shot or miss on the first two shots and make the basket on the third shot.

Required probability

= (0.70) + (0.3×0.7) + (0.3×0.3×0.7)

= 0.70 + 0.21 + 0.063 = 0.973

Which answer would go with this problem (match the quadratic graph to an equation)

lara31 [8.8K]

Answer:

Second (middle) option

Step-by-step explanation:

You can clearly tell from the graph that the y intercept is at 0,0

in $ax^2+bx+c$ , c is always the y value of the y-intercept

in this case the value is 0 so there shouldn't be a visible "c" in the equation, which is why the answer is the middle option

Find the value of y.

Leno4ka [110]

Answer:

$\sqrt{55}$

Step-by-step explanation:

Based off of what we do know, if we can find length DB we can use the pythagorous theorem (I will be assigning the variable z)

$x^{2} =36+z^{2} \\\\y^{2}=25+z^2\\\\x^{2} +y^2=121\\\\$

First equation is for triangle ABD

Second is for BCD

And the last one is for ACD

Substitute $x^{2}$ and $y^2$

$36+z^2+25+z^2=121\\\\61+2z^2=121\\\\2z^2=60\\\\z^2=30\\\\z=\sqrt{30}$

As discovered before

$y^2=25+z^2\\\\y^2=25+30\\\\y^2=55\\\\y=\sqrt{55}$

The answer is B : the square root of 25 is 5, because 5x5=25. So it's 18-5.... Hope I helped :)
