Answer:

The (prediction) for the number of times the spinner <u>wont</u> land on green is 14 times.

Step-by-step explanation:

First you need to find the possibility it will land on green. since there are 2 green spaces out of 9 possible spaces, there is a 2/9 chance you <u>will</u> get green from spinning. <u>This means there is a 7/9 chance you won't get green from spinning once.</u> By multiplying the fraction by the number of times you will spin, it is most likely you will get green 14 times out of 18 spins.

Musya8 [376]

Answer:

a) P(NP/L) = 0.1

b) P(P/L) = 0.9

c) P(P) = 0.666

d) P(L/P) = 0.945

e) P(NL U NP) = 0.37

Step-by-step explanation:

given that;

P = passing the course, NP = Not passing the course, L = Using lab, NL = not using Lab

P(L) = 70% = 0.7, P(NL) = 30% = 0.3

P(P/L) = 90% = 0.9

P(P/NL) = 12% = 0.12

the probability of not passing the course given that the student went to the Learning Lab

P(NP/L) = 1 - P(P/L)

P(NP/L) = 1 - 0.9

P(NP/L) = 0.1

the probability of using the Learning Lab and passing the course

P(P/L) = 0.9

the probability of passing the class

P(P) = P(P/L) * P(L) + P(P/NL) * P(NL)

= (0.9 * 0.7) + (0.12 * 0.3)

P(P) = 0.666

the probability that a student utilized the Learning Lab given the condition that the student passed the class

P(L/P) = [P(P/L) * P(L)] / P(P)

P(L/P) = (0.9 * 0.7) / 0.666 = 0.63/0.666

P(L/P) = 0.945

the probability of not using the Learning Lab or not passing the class

P(NL U NP) = P(NL) + P(NP) - P(NP n NL)

= 0.3 + 0.334 - (0.88 * 0.3 )

= 0.634 - 0.264

P(NL U NP) = 0.37

An aquarium has a base in the shape of a trapezoid. The base is 100

Nat2105 [25]

Answer:

$Volume = 210L$

Step-by-step explanation:

Given

Base:

$Front = 100cm$

$Back = 50cm$

$Width = 40cm$

$Height = 70cm$

Required

Determine the volume (in litres)

First, we need to calculate the area;

Base on the parameters given, we have:

$Area = \frac{1}{2}(Front + Back) * Width$

$Area = \frac{1}{2}(100cm + 50cm) * 40cm$

$Area = \frac{1}{2}(150cm) * 40cm$

$Area = 75cm * 40cm$

$Area = 3000cm^2$

$Volume = Area * Height$

$Volume = 3000cm^2 * 70cm$

$Volume = 210000cm^3$

$1cm^3 = 0.001L$

So:

$Volume = 210000 * 0.001L$

$Volume = 210L$

REPRESENT A PROBLEM: Six friends share 5 meat pies. Each friend first eats half of a meat pie. How much more meat pie does each

lord [1]

I cannot draw a picture, you can.

6 friends multiplied by 1/2 a pie each is 3 pies. That leaves 2 pies to divide evenly among 6 friends. 2/6 = 1/3. One third more pie more for everyone.

two concentric circular regions have radii of $1$ inch and $10$ inches. what is the area, in square inches, outside the smaller

Llana [10]

The area, in square inches, outside the smaller region, but inside the larger region is 99π

<h3>How to determine the area, in square inches, outside the smaller region, but inside the larger region?</h3>

The given parameters are:

Radius, r1 = 1 inch

Radius, r2 = 10 inches

The area, in square inches, outside the smaller region, but inside the larger region is calculated as

Area = π(R^2 - r^2)

This gives

Area = π(10^2 - 1^2)

Evaluate the difference

Area = 99π

Hence, the area, in square inches, outside the smaller region, but inside the larger region is 99π
