y = 3x - 1

y = x - 4

y = 5x + 6

Answer:

Answer:

Step-by-step explanation:

Point-slope form:-

step1:-

The standard of point - slope form is

Give equation is Y-5=6(x+1)

simplification is

This is the form of slope-intercept form

here m is the slope of the line

and y - intercept is c

so m=6 and y- intercept is 11

Step 2:-

Given option

here the y- intercept is 11

so final answer is

Answer: The first choice, y=kx*11, should be the answer.

Slope intercept form can be shown as y=Mx+b. Do tho this first you want to distribute on the left side of the equation so that you get y-5=6x+6. Next you want to add by 5 on both sides to isolate y which will give you y=6x+11

Pleaseeeee Helpppppppp!!!!!A bag contains five green marbles and seven yellow marbles. You randomly select three marbles. What is the probability that all three marbles are green when (a) you replace each marble before selecting the next marble, and (b) you do not replace each marble before selecting the next marble? Write each probability as a decimal rounded to the nearest thousandth. Then compare the probabilities.I don't know how to do this please help me!!!!

P(selecting three green marbles after replacing )=0.072

P(selecting three green marbles without replacing )=0.045

probability of selecting three green marbles after replacing is greater than the probability of selecting three green marbles without replacing

Given :

A bag contains five green marbles and seven yellow marbles. You randomly select three marbles.

There are 5 green marbles and seven yellow marbles.

Total marbles = 5+7=12 marbles

we need to select 3 marbles from 12 marbles

(a) all the three marbles are green and you replace each marbles before selecting the next marble

Probability of an event = number of events occurred by total outcomes

P(selecting first green )=

P(selecting second green )=

P(selecting third green )=

P(selecting three green marbles )=

(b) you do not replace each marble before selecting the next marble

P(selecting first green)=

P(selecting second green )=

P(selecting third green)=

P(selecting 3 green without replacing)=

Answer:

(a) = 0.072 (b) = 0.045

Step-by-step explanation:

(a). The probability of picking a green marble is 5/12 because there are 5 green marbles and 12 marbles in total. Because we replace the marble, this is the probability for all three times we pick a marble. Now to find the total probability we need to times them together. We multiply because the two probabilities are independent of each other, one probability doesn't depend on another probability.

So the answer for (a) = 5/12 × 5/12 × 5/12 = 125/1728 = 0.072

(b). The probability that a green marble is picked the first time is 5/12, the probability that a green marble is picked the 2nd time is 4/11 because we don't replace the marble now we have one less green marble and one marble less in total. The probability that we pick a green marble the 3rd time is 3/10 again because we don't replace the marble. Again, these probabilities are independent so we multiply them.

So the answer for (b) = 5/12 × 4/11 × 3/10 = 60/1320 = 0.045

Find a close estimate for square root of 45. (without a calculator) Round your answer two decimal places

You know that 7*7 is 49, and 6*6 is 36. Now you know it will be 6._. 6*7 is 42, so think of that as 6.5^2. You know that it will most likely be less than 6.8 since it is so close to being 7*7, which is 4 above your desired number. This leaves 6.6 to 6.8 as your estimate. Personally, I would go straight in the middle and choose 6.7.

I hope this helps!

A gift box in the shape of a rectangular prism measures 8 inches by 8 inches by 10 inches. What is the least amount of wrapping paper needed to wrap the gift box?

You need to calculate the total surface area of the rectangular prism. There are 6 faces total, the two on the top and the bottom will be the same while the area of the other four sides will be the same. Starting with the top and bottom, 8x8=64in^2. Now multiply this by two to get 128in^2. Now the sides will be 8x10=80in^2. Multiply this by four to get 320in^2. Now add 128in^2 plus 320in^2 to get 448in^2.

Harry the hippo is munching on the lily pads in his pond. When he arrived at the pond, there were 20 lily pads, but he is eating 4 lily pads an hour. Heinrick the hungrier hippo found a better pond with 29 lily pads! He eats 7 lily pads every hour. Part A.) If Harry and Heinrick start eating at the same time, when will their ponds have the same number of lily pads remaining?

(PLEASE ANSWER THIS ONE)

Part B.) How many lily pads will be left in each pond at the same time.

Answer:

After the 3rd hour

8 lily pads

Step-by-step explanation:

This is quite straight forward and require no deep mathematics.

Harry has 20 lily pads to eat and he eats 4 per hour. After the first hour, he eats 4 and he has 16 left. After second hour, he eats another 4 and he has 12 left. After third hour, he eats four and has eight left.

For Hennrick, he has 29 lily pads and he eats 7 per hour. After first hour, he has 22 left. After second hour, he eats another 7 and have 15 left. After 3rd hour, he eats another 7 and has just 8 left.

8 lily pads will be left at the same time
