Answer:
1. 6 square feet 2. 32ft
Step-by-step explanation:
1. 2x3=6
2. 8 times how many sides so that would be 8x4 which would equal 32
Answer:
-2
Step-by-step explanation:
We have to multiply 10 and 
Here we have to distribute the negative sign.
Distributive property = -(a) = -a
Using the above property, we get = 
Now we have to multiply 10 and
= 10 ×
= 
= 
Now we have to divide -10 by 5.
= -2
Answer:
L= 10 in
W= 7 in
Step-by-step explanation:
Given data
let the widht be x
W= x
L= x+3
P=34 in
We know that
P=2L+2W
34= 2(x+3)+ 2(x)
34= 2x+6+2x
collect like terms
34= 4x+6
34-6= 4x
28= 4x
divide both sides by 4
x= 28/4
x=7
Put x= 7 in
L= x+3
L= 7+3= 10
Hence the width is 7in the length is 10 in
Answer:
a. answer to a can be found in the attached file
b. Pr[survival] = Pr[good&survive]+Pr[medium&survive]+Pr[low&survive]=
0.24+0.06+0.05 = 0.35
c. Assume that the seed has a 0.2 chance of dying before it lands in a habitat. What is its overall probability of survival?
Pr[survival] = Pr[survival|lands] * Pr[lands] = 0.35 * 0.2 = 0.07
Step-by-step explanation:
"A seed randomly blows around a complex habitat. It may land on any of three different soil types: a high-quality soil that gives a 0.8 chance of seed survival, a medium-quality soil that gives a 0.3 chance of survival, and a low-quality soil that gives only a 0.1 chance of survival. These three soil types (high, medium, and low) are present in the habitat in proportions of 30:20:50, respectively. The probability that a seed lands on a particular soil type is proportional to the frequency of that type in the habitat. a. Draw a probability tree to determine the probabilities of survival under all possible circumstances. b. What is the probability of survival of the seed, assuming that it lands"c. Assume that the seed has a 0.2 chance of dying before it lands in a habitat. What is its overall probability of survival?
a. Find the probability tree as attached below
b. Pr[survival] = Pr[good&survive]+Pr[medium&survive]+Pr[low&survive]=
0.24+0.06+0.05 = 0.35
c. Assume that the seed has a 0.2 chance of dying before it lands in a habitat. What is its overall probability of survival?
Pr[survival] = Pr[survival|lands] * Pr[lands] = 0.35 * 0.2 = 0.07
Answer:
5y - 2x = 0
Step-by-step explanation:
Equation of line is given by,
y - y1 = ( x - x1 ) ( y2 - y1)/ (x2 - x1 )
y - 0 = ( x - 0 ) ( 2 - 0 )/ ( 5 - 0 )
y = 2x /5
5y = 2x
5y - 2x = 0
This is the required equation.
