Volume of a Cone = (1/3)*(pi)*(radius)*(radius)*(height)
we are given:
pi = 3.14
height = 6
Volume = 8(3.14)
plug in
8(3.14) = (1/3)*(3.14)*(radius)^2 *(6)
8 = (1/3)*(6)*(radius)^2 [divided both sides by 3.14]
8 = (2)*(radius)^2 [simplified (1/3)*(6)]
4 = (radius)^2 [divided 2 from both sides]
radius = 2 [square rooted both sides (sqrt(4))=2]
therefore the radius = 2 ft
Answer:
The solution to the inequality 89 – 9.8t < 10.6 is ?
t > 8
The solution to the inequality 89 – 9.8t > 20.4 is?
t < 7
To determine when the projectile hits the ground, solve 89 – 9.8t = 0 for t.
t = 9.08163265306
Rounding to the nearest whole second, t is about ?
9 seconds.
The viable solution set is ?
[0, 7) or (8, 9]
Answer:
Option D. -0.901
Step-by-step explanation:
we know that
<u>The correlation coefficient</u> r measures the strength and direction of a linear relationship between two variables. The value of r is always between +1 and –1
Using a Excel tool (Correl function)
The value of coefficient r is -0.9006876
Round to three decimal places
r=-0.901
see the table attached

Answer:
<h2>1/5</h2>
Step-by-step explanation:
The sample space for pens is
5 red pens, 6 blue pens, 3 black pens,(5+6+3)= 14pens
The sample space for paper is
4 silver paper clips and 16 white (4+16)=20 papers
The probability of selecting a black pen and white paper
Pr(black pen)*Pr(white paper)
=3/14*16/20
=48/280
= 14/70
= 2/10
= 1/5
