seraphim [82]
<h2>Answer: He makes 261 baskets to earn 45 points.</h2>

Step-by-step explanation:

Since we have given that

Number of points = 2 + 3 = 5

Number of baskets = 29

if he makes 45 points,

We need to find the number of baskets.

According to question, we get that

\dfrac{5}{29}=\dfrac{45}{x}\\\\5x=45\times 29\\\\x=\dfrac{45\times 29}{5}\\\\x=261

Hence, he makes 261 baskets to earn 45 points.

a football is fired upward with an initial speed of 800 feet per second. It is given that h=-12t^2+360t (h is the height of the
tangare [24]

Answer:

30 s

Step-by-step explanation:

When the ball hits the ground h=0. To find the time t when this happens we must solve the equation h=0.

●h= 0

● -12t^2+360t =0

● t(-12t +360) = 0

● t = 0 or -12t +360 =0

● t=0 or -12t = -360

● t=0 or 12t =360

● t=0 or t=360/12

● t=0 or t= 30

The equation has two solutions.

The ball was fired with an initial speed of 800 feet per second so it cannot hit the ground at t=0.

So the ball hits the ground after 30 s.

marusya05 [52]

Answer:

Step-by-step explanation:

Given that there is a t distribution with 7 degrees of freedom.

P(-1.29 < t < 1.29)=1-0.2380

=0.7620

b) Now there is a different t distribution with 18 df.

When P(t\leq c)=0.05

c=-1.733
